Description

Technical Field

[0001] The invention relates to the technical field of air conditioners, and in particular to a valve body assembly applied to an air conditioner refrigeration cycle system. 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. Air conditioning generally includes several major parts such as cold source and heat source equipment, cold and hot medium distribution systems, terminal devices, and other auxiliary equipment, mainly including refrigeration hosts, water pumps, fans, and piping systems. The terminal device is responsible for utilizing the distributed cold and heat to specifically process the air state so that the air parameters of the target environment meet certain requirements.

[0003] The air conditioning refrigeration cycle system refers to a system that uses external energy to transfer heat from a substance with a lower temperature to a substance with a higher temperature. In this process, the system uses refrigerant as the working medium and performs physical changes of absorbing and releasing heat in the cycle to achieve the refrigeration effect. The four-way valve assembly mainly plays the role of a refrigerant conversion intermediate station in the air conditioning refrigeration cycle system. When the air conditioner compressor discharges huge energy, the four-way valve assembly provides it with an intermediate transfer platform.

[0004] However, after the four-way valve assembly has been used in the air conditioner for a long time, dust will be deposited in the flow channels of multiple connecting pipes on the four-way valve, causing the flow channels to narrow or even become blocked, which will reduce the flow velocity of the refrigerant gas and increase the flow resistance, thereby affecting the refrigeration cycle system of the air conditioner.

[0005] Furthermore, during the energy transfer and conversion process of the four-way valve assembly, the flow rate of the refrigerant gas inside the connecting pipe used to connect the four-way valve with the air-conditioning compressor, condenser and evaporator cannot be adjusted and cannot be changed according to the flow demand, which is not conducive to use.

[0032] The outlet pipe 1 7 is provided with a regulating component for controlling the flow rate of the refrigerant gas in the flow passages of the outlet pipe 1 7 , the outlet pipe 2 6 and the outlet pipe 3 5 ;

[0033] The cleaning tube 12 is provided with a cleaning component, and the cleaning tube 12 is also provided with an auxiliary component.

[0034] Capillary 1 8, capillary 2 9, capillary 3 10 and capillary 4 11 are provided on the pilot valve seat 2. The end of capillary 1 8 is fixedly connected to the incoming pipe 4, capillary 2 9 is fixedly connected to the outgoing pipe 2 6, and capillary 3 10 and capillary 4 11 are fixedly connected to the two sides of the four-way valve body 1 respectively.

[0035] The inlet pipe 4 and the outlet pipe 2 6 are connected to the air conditioner compressor, the outlet pipe 1 7 is connected to the air conditioner evaporator, and the outlet pipe 3 5 is connected to the air conditioner condenser.

[0036] In this embodiment, the four-way valve body 1 is connected to the air conditioner compressor through the access pipe 4, and is used to receive the high-temperature and high-pressure refrigerant gas discharged from the compressor, and returns the low-temperature and low-pressure refrigerant gas to the compressor for re-compression through the access pipe 2 6, and is connected to the air conditioner evaporator through the access pipe 1 7 to realize the cooling or heating function of the indoor unit, and is connected to the air conditioner condenser through the access pipe 3 5 to realize the condensation heat release of the outdoor unit, and then through the capillary 1 8, the capillary 2 9, the capillary 3 10 and the capillary 4 11, the refrigerant gas is transmitted between the four-way valve body 1 and the pilot valve seat 2 to complete the refrigeration cycle of the air conditioner. This is a relatively mature existing technology in the field of air conditioners and will not be described in detail here.

[0037] Further, the adjustment component includes a limit frame 35 fixedly mounted on the surface of the outlet pipe 7, the inner wall of the limit frame 35 is fixedly connected to two symmetrically arranged limit rods 34, the surfaces of the two limit rods 34 are slidably connected to a mounting plate 31, a motor 30 is fixedly mounted on the end of the mounting plate 31, a controller 29 is arranged on the surface of the motor 30, and a sleeve 33 is fixedly connected to the output shaft of the motor 30;

[0038] The inner walls of the access tube 1 7, the access tube 2 6 and the access tube 3 5 are connected to a rotating rod 19 for fixed axis rotation. The surface of the rotating rod 19 is fixedly connected to a plurality of arc-shaped protrusions 32 distributed in a circular array.

The motor 30 can drive the sleeve 33 to rotate. Since the inner wall of the sleeve 33 is provided with a plurality of arc-shaped protrusions 32 and slots for the rotating rod 19 to slide and fit, the rotation of the sleeve 33 can drive the rotating rod 19 to rotate synchronously, and the rotation of the rotating rod 19 will drive the three adjusting disks 20 to rotate with the rotating rod 19 as the axis, so as to be able to change the flow rate in the outlet pipe 1 7, the outlet pipe 2 6 and the outlet pipe 3 5 according to the real-time use needs.

Figure 2 In the state shown, the inclined adjustment disk 20 can block the circulation of most of the refrigerant gas in the pipeline to reduce the flow rate, thereby reducing energy consumption and achieving energy-saving effects.

[0040] Embodiment 2, based on the above embodiment:

[0041] Furthermore, the cleaning components and auxiliary components in the first embodiment are disclosed as follows: the cleaning components include a connecting piece 13 fixedly connected to the lower surface of the cleaning pipe 12, the connecting piece 13 is arranged in an inverted convex shape, and the lower surface of the connecting piece 13 is fixedly connected to a connecting pipe 17, on which a solenoid valve is arranged, and an end of the connecting pipe 17 extends out of the outside of the air conditioner, and a pump body 14 is arranged on the connecting pipe 17, and a fixing plate 16 is arranged on the pump body 14 at any time, and a mounting hole 15 is opened on the surface of the fixing plate 16.

[0042] The auxiliary component includes a mounting block 40 fixedly connected to the surface of the cleaning tube 12, a protective shell 22 is fixedly mounted on the upper surface of the mounting block 40, a rotating shaft 24 is fixedly connected to the inner wall of the cleaning tube 12, an impeller 26 is arranged at one end of the rotating shaft 24 extending into the cleaning tube 12, an end of the rotating shaft 24 extending out of the cleaning tube 12 is fixedly connected to the protective shell 22, a disc 25 is fixedly connected to the surface of the rotating shaft 24, and a plurality of triangular teeth 38 distributed in a circumferential array are arranged on the surface of the disc 25;

[0043] The inner wall of the protective shell 22 is also rotatably connected to the second rotating shaft 23, the surface of the second rotating shaft 23 is fixedly connected to the connecting disk 18, the surface of the connecting disk 18 is fixedly connected to the lever 37, the surface of the connecting disk 18 is also fixedly connected to the swing rod 27, the end of the swing rod 27 is provided with a knocking ball 28, and the outer surface of the knocking ball 28 is provided with a rubber layer.

[0044] The circular housing 21 is fixedly mounted on the inner wall of the protective housing 22 , and a coil spring 39 is disposed at the end of the second rotating shaft 23 extending into the circular housing 21 .

[0045] In the present embodiment, when the four-way valve body 1 needs to be cleaned after being used for a long time, the air conditioner is first turned off to stop the generation of refrigerant and the refrigeration cycle of the air conditioner. Then, the solenoid valve on the surface of the connecting pipe 17 is opened, and then the pump body 14 is opened. As the pump body 14 is opened, the dust and impurities accumulated on the inner walls of the outlet pipe 1 7 , the outlet pipe 2 6 and the outlet pipe 3 5 can be sucked into the connecting piece 13 through the three cleaning pipes 12 under the action of the suction force of the pump body 14. The dust and impurities will finally be discharged to the outside of the air conditioner through the connecting pipe 17. The dust cleaning work in the multiple connecting pipes on the four-way valve body 1 can be completed without opening the entire air conditioner, thereby avoiding the problem that the flow channel in the pipe becomes narrower or even blocked due to dust accumulation, reducing the flow resistance, facilitating the flow of the refrigerant gas in the pipe, ensuring the operation of the refrigeration cycle system after the air conditioner is turned on, and extending the service life of the air conditioner.

[0046] After long-term use, the adjustment disks 20 in the outlet pipe 1 7, the outlet pipe 2 6 and the outlet pipe 3 5 will also be adhered to some dust and impurities on their surfaces. Before the dust is cleaned, the motor 30 will drive the adjustment disk 20 to rotate to the position as shown in FIG. Figure 2 In the state shown, under the action of the suction force of the pump body 14, the dust and impurities on the upper surface of the adjusting disk 20 can be sucked into the cleaning tube 12 along the adjusting disk 20 and the inner wall of the pipe, and the dust attached to the other side of the adjusting disk 20 will be directly adjusted into the inner wall of the pipe under the action of gravity, and will also be sucked into the cleaning tube 12 along the inner wall of the pipe, so that the dust on the inner walls of the three pipes of the connecting pipe 1 7, the connecting pipe 2 6 and the connecting pipe 3 5 can be cleaned at the same time, and the dust on the adjusting disk 20 can be effectively cleaned synchronously, which is more practical.

[0047] It is worth noting that as the pump body 14 is turned on, the air in the cleaning pipe 12 will drive the impeller 26 to rotate, and as the impeller 26 rotates, the shaft 1 24 will be driven to rotate synchronously. Figure 2 , Figure 5 and Figure 6 As shown, with the rotation of the rotating shaft 1 24, the disc 25 and the plurality of triangular teeth 38 are driven to rotate synchronously. With the rotation of the plurality of triangular teeth 38, when one triangular tooth 38 contacts the lever 37, the lever 37 is pushed to move a short distance. With the movement of the lever 37, the connecting disc 18 and the rotating shaft 23 are driven to rotate a short distance. At the same time, the coil spring 39 connected to one end of the rotating shaft 23 extending into the circular shell 21 also begins to wind up and store force. With the rotation of the connecting disc 18, the swing rod 27 is caused to rotate synchronously a short distance, so that the knocking ball 28 can knock the outer wall of the receiving tube 1 7 once. With the continued rotation of the triangular teeth 38, when the triangular teeth 38 are disengaged from the lever 37, the elastic potential energy of the coil spring 39 drives the rotating shaft 23 and the connecting disc 18 to reset, so that the lever 37 can be reset, until the next triangular tooth 38 contacts the lever 37 again, and the above operation is repeated.

[0048] That is, after the pump body 14 is turned on, as the impeller 26 rotates, the striking ball 28 at the end of the swing rod 27 will reciprocately hit the outer wall of the outlet pipe 1 7. When the vibration is transmitted to the inner wall of the outlet pipe 1 7, the dust and impurities on the inner wall of the outlet pipe 1 7 can be better shaken off, so that the dust in the outlet pipe 1 7 can be better cleaned. Similarly, the outlet pipes 2 6 and 3 5 will also vibrate, and the cleaning effect is better.

[0049] Furthermore, buffer springs 36 are disposed between the mounting plate 31 and the inner wall of the limiting frame 35 . There are two groups of buffer springs 36 symmetrically distributed on the mounting plate 31 .

[0050] As the outlet pipe 7 vibrates, the motor 30 will inevitably vibrate slightly. By providing two sets of buffer springs 36, the vibration force on the motor 30 can be buffered, thereby reducing the impact of the vibration force on the motor 30 and extending the service life of the motor 30.

[0051] Working principle: This valve body assembly used in the air-conditioning refrigeration cycle system is connected to the compressor, condenser and evaporator in the air conditioner through the connecting pipe 4, the connecting pipe 2 6, the connecting pipe 1 7 and the connecting pipe 3 5 when in use, and then the refrigerant gas is transmitted between the four-way valve body 1 and the pilot valve seat 2 through the capillary tube 1 8, the capillary tube 2 9, the capillary tube 3 10 and the capillary tube 4 11, thereby completing the refrigeration cycle of the air conditioner.

[0052] The controller 29 on the motor 30 is connected to the control terminal of the air conditioner. The motor 30 drives the sleeve 33 and the rotating rod 19 to rotate synchronously, and the rotation of the rotating rod 19 drives the three adjusting disks 20 to rotate with the rotating rod 19 as the axis, so that the flow rate in the outlet pipe 1 7, the outlet pipe 2 6 and the outlet pipe 3 5 can be changed according to the real-time refrigeration temperature in the air-conditioning refrigeration cycle. For example, when a higher refrigeration capacity is required, the adjusting disk 20 is rotated to a position parallel to the inner wall of the pipe to increase the flow rate, thereby accelerating heat exchange and improving the efficiency of the air-conditioning refrigeration cycle; conversely, when the load is small, the adjusting disk 20 is rotated to a position parallel to the inner wall of the pipe to increase the flow rate. Figure 2 In the state shown, the inclined adjustment disk 20 in this state can block the circulation of most of the refrigerant gas in the pipeline, so as to reduce the flow rate, thereby reducing energy consumption and achieving energy-saving effect.

[0053] When the four-way valve body 1 needs to be cleaned after long-term use, the air conditioner is turned off to stop the generation of refrigerant and stop the refrigeration cycle of the air conditioner. Then, the solenoid valve on the surface of the connecting pipe 17 is opened, and then the pump body 14 is opened. With the opening of the pump body 14, the dust and impurities accumulated on the inner walls of the receiving pipe 1 7, the receiving pipe 2 6 and the receiving pipe 3 5 can be sucked into the connecting piece 13 through the three cleaning pipes 12. The dust and impurities will finally be discharged to the outside of the air conditioner through the connecting pipe 17. With the opening of the pump body 14, the impeller 26 will be driven to rotate under the action of the flow of air in the cleaning pipe 12, so as to drive the knocking ball at the end of the swing rod 27. 28 reciprocates and strikes the outer wall of the outlet pipe 1 7. When the vibration is transmitted to the inner wall of the outlet pipe 1 7, the dust and impurities on the inner wall of the outlet pipe 1 7 can be shaken off better. Similarly, the outlet pipes 2 6 and 3 5 will also vibrate, and the dust cleaning effect in the pipeline is better. It is not necessary to open the entire air conditioner to complete the dust cleaning work in multiple connecting pipes on the four-way valve body 1, avoiding the problem of the flow channel in the pipeline becoming narrower or even blocked due to dust accumulation, reducing the flow resistance, and being beneficial to the flow of refrigerant gas in the pipeline. After the air conditioner is turned on, the operation of the refrigeration cycle system is guaranteed, and the service life of the air conditioner is extended.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
