Description

Technical Field

[0001] The utility model relates to the technical field of high-performance fixed-frequency air conditioner maintenance, in particular to a high-performance fixed-frequency air conditioner that is easy to maintain. Background Art

[0002] Air conditioning, or air conditioner, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate of the ambient air in a building or structure. Existing air conditioners are generally divided into fixed-frequency air conditioners and variable-frequency air conditioners. A high-efficiency fixed-frequency air conditioner refers to an air-conditioning system in which the compressor runs at a fixed frequency and cannot automatically adjust power according to actual demand. This type of air-conditioning system will run at full power when working and cannot be adjusted according to changes in indoor temperature. Therefore, when the indoor temperature reaches the set value, the fixed-frequency air conditioner will automatically shut down, and it will need to reach the set temperature again to start again. This type of air conditioner often requires maintenance due to its high energy consumption when in use.

[0003] In the prior art, such as the Chinese patent number: CN219572123U "an air conditioner that is easy to maintain", includes an air conditioner outdoor unit, a mounting mechanism is provided at the bottom of the air conditioner outdoor unit, a base is provided at the bottom of the mounting mechanism, and a positioning mechanism is provided on the top of the base located outside the mounting mechanism. Although this technology reduces the time and danger of workers disassembling the air conditioner outdoor unit through the installation mechanism, this technology still has some defects in actual use: the existing high-performance fixed-frequency air conditioner outdoor unit and the indoor unit are connected by a copper tube to transport refrigerant (Freon). When the air conditioner outdoor unit needs to be disassembled and maintained, the copper tube needs to be disassembled first. In this process, the Freon needs to be collected first to ensure that the Freon in the indoor unit is completely collected in the outdoor unit. To this end, it is necessary to first open the return fluorine pipe to allow the Freon to flow to the outdoor unit, and then close the fluorine outlet pipe , so that the Freon is completely collected in the outdoor unit, and then the return fluorine pipe is closed, and the copper pipe can be removed. However, this technology only simply disassembles the base of the air-conditioning outdoor unit and cannot cause the air-conditioning outdoor unit to be completely separated from the fixing frame. The copper pipe needs to be disassembled. When disassembling the copper pipe, the valves in the existing return fluorine pipe and the fluorine outlet pipe need to be opened and closed using a hexagonal wrench. Since the hexagonal wrench is relatively small, it is inconvenient to use, which leads to the problem of inadequate closure when closing the valve, which leads to the problem of refrigerant loss when collecting fluorine, which in turn causes problems that affect the use of the air conditioner in the later stage. At the same time, since the copper pipe connection is fixed with a hexagonal nut and the copper pipe connection is close to the outdoor unit casing, the wrench operation space is relatively small, making it more difficult to disassemble and maintain. Therefore, these factors cause the problem of inconvenience in disassembly and maintenance of high-performance fixed-frequency air conditioners, which increases the difficulty and time-consuming maintenance.

[0029] The blocking component can replace the traditional valve to block the pipeline, thereby avoiding the problem of refrigerant loss when the traditional hexagonal wrench is used to close the valve. At the same time, it can also quickly block the inside of the fluorine return pipe 2 and the fluorine outlet pipe 3, so as to achieve the purpose of quickly disassembling the copper tube 27, thereby facilitating the maintenance and repair of the air conditioner outdoor unit 1. When collecting fluorine, first use the thread to open the protective cap 18, and press the pressing bolt 17 at the same time. At this time, the bottom of the pressing bolt 17 will push the top of the clamping bolt 14, thereby causing the clamping bolt 14 to shrink to the inside of the pushing bolt 12. At this time, the return force of the positioning spring 13 is used to When the fluorine is completely collected, the push pin 17 on the blocking tube 5 corresponding to the return fluorine tube 2 is pressed, thereby prompting the blocking plug 11 to block the outlet of the return fluorine tube 2, thereby preventing the loss of fluorine.

[0031] By means of the blocking plug 11 and the pushing bolt 12, the blocking plug 11 can be caused to block the inside of the fluorine return tube 2 and the fluorine outlet tube 3, thereby achieving the effect of closing the outlets of the fluorine return tube 2 and the fluorine outlet tube 3, thereby facilitating the later disassembly of the copper tube 27. Meanwhile, by means of the provided clamping bolt 14, the rebound spring and the clamping hole, when opening the inside of the fluorine return tube 2 and the fluorine outlet tube 3, one end of the pushing bolt 12 can be pulled out, causing the clamping bolt 14 to utilize the effect of the rebound spring to be stuck in the clamping hole, thereby achieving the effect of fixing the position of the pushing bolt 12.
