An unloading solenoid valve assembly for an air conditioner

Abstract

This invention discloses an unloading solenoid valve assembly for air conditioners, relating to the field of unloading solenoid valve technology. It includes a valve pipe and a valve body, with a valve seat fixedly installed on the inner wall of the valve pipe. During operation, this unloading solenoid valve assembly allows the flow of fluid to drive a turbine to rotate, thereby enabling several cleaning brushes to clean and agitate the interception holes of the filter screen. This prevents the flow rate within the unloading solenoid valve from being affected. Furthermore, as impurities accumulate and the filter screen becomes increasingly clogged, the gradually increasing fluid pressure causes the filter screen to rise. This not only increases the turbine's rotational speed but also gradually closes the distance between the filter screen and the cleaning brushes, thereby enhancing the cleaning intensity of the interception holes and ultimately improving the stable operation of the refrigeration system.

Description

Technical Field

[0001] This invention relates to the field of unloading solenoid valve technology, specifically to an unloading solenoid valve assembly for air conditioners. Background Technology

[0002] An air conditioner, commonly known as an air conditioner, is an air conditioning device used to regulate indoor air temperature, humidity, airflow, and other parameters. It comes in various forms, including wall-mounted, floor-standing, window-mounted, and built-in types. It mainly consists of four parts: a refrigeration system, an air circulation system, an electrical control system, and a housing system. It has multiple functions such as cooling, heating, dehumidification, air supply, and air purification. Air conditioners are widely used in modern life. They can be seen in homes, offices, shopping malls, and other public places. They not only provide people with a comfortable indoor environment but also improve indoor air quality and enhance people's quality of life through air purification and other functions.

[0003] The unloading solenoid valve is a key component in the air conditioning refrigeration system. It can regulate the pressure in the refrigeration system by controlling the opening and closing state of the valve. When the system pressure reaches the preset value, the unloading solenoid valve will automatically open or close to adjust the cooling capacity, thereby keeping the system pressure within a reasonable range. Because it can adjust the cooling capacity in a timely manner according to changes in the refrigeration system pressure, it can prevent the refrigeration system from malfunctioning due to pressure fluctuations. Therefore, the unloading solenoid valve helps maintain the stable operation of the refrigeration system and plays a vital role in the refrigeration system.

[0004] During the use of unloading solenoid valves, metal components in the refrigeration system, such as copper pipes, steel pipes, and aluminum pipes, will accumulate metal particles and other impurities due to corrosion and wear over long periods of use. These particles will spread throughout the system with the refrigerant flow, causing the flow port of the unloading solenoid valve to narrow or become blocked. Therefore, a filter screen is currently installed at the flow point of the unloading solenoid valve to intercept these particles. However, impurities can still clog the filter screen pores, and the pores cannot be cleaned in time. Since the unloading solenoid valve requires precise control of the refrigerant flow rate and direction, the control accuracy of the unloading solenoid valve is affected, making it impossible to ensure the stable operation of the refrigeration system. Summary of the Invention

[0005] The purpose of this invention is to provide an unloading solenoid valve assembly for an air conditioner to solve the problems mentioned in the background art.

[0007] The bottom of the valve seat is provided with a self-controlled cleaning mechanism, which uses the flow of fluid to clean and agitate the blockage impurities when the unloading solenoid valve is running, and increases the cleaning force of impurities as the amount of impurities increases.

[0008] The inner wall of the valve tube is provided with a vibration-following mechanism so that when the unloading solenoid valve is running, it can collide and vibrate to clear the blockage of impurities.

[0009] Preferably, the self-controlled cleaning mechanism includes an installation ring, and the top of the installation ring is fixedly connected to the bottom of the valve seat corresponding to the flow port. The bottom of the installation ring has a sliding cavity, and the inner wall of the sliding cavity is slidably connected to a connecting ring. The bottom of the connecting ring is fixedly connected to a filter screen, and the filter screen is semi-circular in shape. The outer wall of the filter screen has interception holes that are evenly spaced through it.

[0010] Preferably, the valve tube has an internal cavity, and the inner wall of the valve tube has a second through groove, the inner wall of the second through groove being connected to the inner wall of the cavity. The bottom outer wall of the filter screen has a through groove, and the inner wall of the cavity is rotatably connected to a rotating rod, the top of which extends through the inner wall of the first through groove and into the interior of the filter screen.

[0011] Preferably, a turbine is fixedly connected to the outer wall of the extension end of the rotating rod, and an arc-shaped strip is fixedly connected to the outer wall of the extension end of the rotating rod. Cleaning brushes are fixedly connected to the outer wall of the arc-shaped strip at equal intervals corresponding to the interception holes. An adaptive spring is provided on the inner wall of the sliding cavity. One end of the adaptive spring is fixedly connected to the top of the connecting ring, and the other end of the adaptive spring is fixedly connected to the inner wall of the sliding cavity.

[0012] Preferably, the following vibration mechanism includes a slide cylinder, and a sliding hole is provided through the interior of the slide cylinder. The inner wall of the sliding hole slides in contact with the outer wall of the rotating rod. An annular groove is provided on the outer wall of the slide cylinder, and a slider is slidably connected to the inner wall of the annular groove. The outer wall of the slider is fixedly connected to the inner wall of the through groove.

[0013] Preferably, a return spring is fitted to the inner wall of the annular groove. One end of the return spring is fixedly connected to the top of the slider, and the other end of the return spring is fixedly connected to the inner wall of the annular groove. The bottom of the slide cylinder extends through the inner wall of the through groove to the inner wall of the cavity, and a support plate is fixedly connected to the bottom of the slide cylinder. The outer wall of the support plate slides in contact with the inner wall of the cavity.

[0014] Preferably, the inner wall of the valve pipe is symmetrically provided with a sliding groove with the through groove two as the vertical line, and the inner wall of the sliding groove is connected to the inner wall of the cavity. The inner wall of the sliding groove is slidably connected with a collision column, and the bottom of the collision column is in contact with the top end face of the support plate.

[0016] Preferably, the inner wall of the second through groove is fixedly connected with a ball bearing corresponding to the spiral groove, and the outer wall of the ball bearing slides in contact with the inner wall of the spiral groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. When the unloading solenoid valve is running, the flow of fluid drives the turbine to rotate, which in turn allows several cleaning brushes to clean and agitate the interception holes of the filter screen, preventing the flow rate within the unloading solenoid valve from being affected. Simultaneously, as impurities accumulate and the filter screen becomes increasingly clogged, the gradually increasing fluid pressure causes the filter screen to rise. This not only increases the turbine's rotational speed but also gradually closes the distance between the filter screen and the cleaning brushes, thereby enhancing the cleaning intensity of the interception holes and ultimately improving the stable operation of the refrigeration system.

[0019] 2. When the solenoid valve is running, the gradual rise of the filter screen and the synchronous rotation of the slide cylinder by the cooperation of the ball bearings and the spiral groove allow the three guide blocks to continuously guide the collision column that is in contact with the filter screen. This results in continuous collision and vibration of the filter screen during the rising process, which helps to improve the unblocking efficiency of the filter screen and thus improves the stable operation of the refrigeration system.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1, please refer to Figure 1-6 The present invention provides an unloading solenoid valve assembly for an air conditioner, including a valve pipe 1 and a valve body 2. A valve seat 3 is fixedly installed on the inner wall of the valve pipe 1, and a flow port 4 is provided through the middle of the valve seat 3.

[0029] A self-cleaning mechanism 5 is provided at the bottom of the valve seat 3.

[0030] Furthermore, the self-control cleaning mechanism 5 includes an installation ring 501, and the top of the installation ring 501 is fixedly connected to the bottom of the valve seat 3 corresponding to the flow port 4. The bottom of the installation ring 501 is provided with a sliding cavity 502, and the inner wall of the sliding cavity 502 is slidably connected to a connecting ring 503. The bottom of the connecting ring 503 is fixedly connected to a filter screen 504, and the filter screen 504 is semi-circular in shape. The outer wall of the filter screen 504 is provided with interception holes 505 at equal intervals.

[0031] In this embodiment, when adjusting the fluid flow rate of the air conditioner's refrigeration system, the flow rate of the flow port 4 can be adjusted by using the electromagnet inside the valve body 2 to control the raising and lowering of the valve stem, thereby controlling the pressure of the refrigeration system and protecting the normal operation of the air conditioner.

[0032] Next, with the flow port 4 in the open state, the refrigerant in the valve pipe 1 will flow from left to right. At this time, the top of the mounting ring 501 is fixedly connected to the bottom of the valve seat 3 corresponding to the flow port 4. The bottom of the mounting ring 501 is provided with a sliding cavity 502, and the inner wall of the sliding cavity 502 is slidably connected to a connecting ring 503. At the same time, the bottom of the connecting ring 503 is fixedly connected to a filter screen 504. The filter screen 504 is semi-circular in shape, and the outer wall of the filter screen 504 is provided with interception holes 505 at equal intervals. Thus, the impurity particles in the fluid can be blocked through the interception holes 505 of the filter screen 504 and intercepted outside the filter screen 504.

[0033] Next, when the refrigerant fluid flows normally through the flow port 4, a rotating rod 506 is rotatably connected to the inner wall of the cavity 7. The top of the rotating rod 506 extends through the inner wall of the through groove 8 to the inside of the filter screen 504. A turbine 507 is fixedly connected to the outer wall of the extended end of the rotating rod 506. The flow of fluid drives the turbine 507 to rotate, which in turn drives the rotating rod 506 to rotate. Then, an arc-shaped strip 508 is fixedly connected to the outer wall of the extended end of the rotating rod 506. A cleaning brush 509 is fixedly connected to the outer wall of the arc-shaped strip 508 at equal intervals to the interception hole 505. The arc-shaped strip 508 drives several cleaning brushes 509 to clean and agitate the impurities blocking the interception hole 505 from the inside of the filter screen 504, thereby clearing the filter screen 504, ensuring the flow of fluid, and thus ensuring the stable operation of the refrigeration system.

[0034] Furthermore, under normal conditions, i.e. when the filter screen 504 is less clogged, an adaptation spring 510 is provided on the inner wall of the sliding cavity 502. One end of the adaptation spring 510 is fixedly connected to the top of the connecting ring 503, and the other end of the adaptation spring 510 is fixedly connected to the inner wall of the sliding cavity 502. Thus, the elastic resistance of the adaptation spring 510 can keep the inner wall of the filter screen 504 and the cleaning brush 509 at a suitable distance. That is, the inside of the filter screen 504 and the end of the cleaning brush 509 are in contact and agitated. In this way, while maintaining a suitable cleaning and agitation effect, the friction and wear between the cleaning brush 509 and the inside of the filter screen 504 can be reduced, thereby improving the service life of this component.

[0035] As impurities gradually increase, the degree of blockage in the filter screen 504 will increase. As the number of flowable interception holes 505 decreases, the flow pressure of the fluid in the valve pipe 1 increases, thereby increasing the thrust on the filter screen 504 and causing it to rise. As the filter screen 504 rises, its interior will come into contact with and agitate the middle or even near the root of the cleaning brush 509. Compared to the agitation at the end of the cleaning brush 509, the agitation force in the middle and root of the cleaning brush 509 will be greater and stronger, thereby gradually improving the cleaning and agitation effect of the cleaning brush 509 on the interception holes 505. At the same time, the increased fluid pressure can increase the rotation speed of the turbine 507, thereby improving the cleaning and agitation efficiency of the cleaning brush 509 on the filter screen 504, so as to achieve the effect of automatically controlling the cleaning and unblocking intensity.

[0036] As described above, during the operation of the unloading solenoid valve, the flow of fluid drives the turbine 507 to rotate, thereby enabling several cleaning brushes 509 to clean and agitate the interception holes 505 of the filter screen 504, preventing the flow rate within the unloading solenoid valve from being affected. Simultaneously, as impurities accumulate and the filter screen 504 becomes increasingly clogged, the gradually increasing fluid pressure causes the filter screen 504 to rise. This not only increases the rotational speed of the turbine 507 but also gradually closes the distance between the filter screen 504 and the cleaning brushes 509, thereby enhancing the cleaning intensity of the cleaning brushes 509 in clearing the interception holes 505, ultimately contributing to the stable operation of the refrigeration system.

[0037] In Example 2, based on the above examples, the inner wall of the valve pipe 1 is provided with a vibration-following mechanism 6.

[0038] Furthermore, the following vibration mechanism 6 includes a slide cylinder 601, and a sliding hole 602 is provided through the inside of the slide cylinder 601. The inner wall of the sliding hole 602 slides against the outer wall of the rotating rod 506. An annular groove 603 is provided on the outer wall of the slide cylinder 601, and a slider 604 is slidably connected to the inner wall of the annular groove 603. The outer wall of the slider 604 is fixedly connected to the inner wall of the through groove 8.

[0039] In this embodiment, under normal conditions, an annular groove 603 is provided on the outer wall of the slide cylinder 601, and a slider 604 is slidably connected to the inner wall of the annular groove 603. The outer wall of the slider 604 is fixedly connected to the inner wall of the through groove 8. At the same time, a return spring 605 is provided on the inner wall of the annular groove 603, and one end of the return spring 605 is fixedly connected to the top of the slider 604, and the other end of the return spring 605 is fixedly connected to the inner wall of the annular groove 603. Thus, the filter screen 504 can support the slide cylinder 601 through the fixed connection between the filter screen 504 and the slider 604.

[0040] Next, the elastic resistance of the reset spring 605 causes the slider 604 to be located in the lower inner wall of the annular groove 603, that is, the filter screen 504 has a certain upward space through the slider 604. Then, the bottom of the slide cylinder 601 extends through the inner wall of the through groove 11 to the inner wall of the cavity 7, and the bottom of the slide cylinder 601 is fixedly connected to the support plate 606. The outer wall of the support plate 606 slides against the inner wall of the cavity 7. At the same time, the inner wall of the slide groove 10 is slidably connected to the collision post 607, and the bottom of the collision post 607 is in contact with the top end face of the support plate 606. Thus, under normal conditions, the bottom outer wall of the filter screen 504 is in contact with the top of the two collision posts 607 and can move synchronously with the filter screen 504.

[0041] As the filter screen 504 gradually rises, it simultaneously drives the slide cylinder 601 to rise as well. A spiral groove 609 is correspondingly formed on the outer wall of the slide cylinder 601, and a ball bearing 9 is fixedly connected to the inner wall of the through groove 11 corresponding to the spiral groove 609. The outer wall of the ball bearing 9 slides in contact with the inner wall of the spiral groove 609. Therefore, during the rising process of the slide cylinder 601, the cooperation between the ball bearing 9 and the spiral groove 609 allows the slide cylinder 601 to rotate synchronously during the rise. Then, the top end face of the support plate 606 is fixed at equal intervals to the collision post 607. The guide block 608 is fixedly connected, and the two side walls of the guide block 608 are set in an inclined shape corresponding to the collision column 607. This allows the three guide blocks 608 to move in a circle by rotating the support plate 606, and the inclined surface drives the collision column 607 to rise quickly to lift the filter screen 504. At the same time, when it is not in contact with the guide block 608, the return spring 605 can drive the filter screen 504 to fall back to its original position. This allows the filter screen 504 to be continuously impacted and vibrated during the rising process, which helps to improve the unblocking efficiency of the filter screen 504.

[0042] As described above, during the operation of the unloading solenoid valve, the gradual rise of the filter screen 504, combined with the cooperation of the ball bearing 9 and the spiral groove 609, synchronously drives the slide cylinder 601 to rotate. This allows the three guide blocks 608 to continuously guide the collision column 607 that is in contact with the filter screen 504, resulting in continuous collision and vibration of the filter screen 504 during the rising process. This improves the unblocking efficiency of the filter screen 504 and, consequently, enhances the stable operation of the refrigeration system.

[0043] Working principle: First, when adjusting the fluid flow rate of the air conditioner's refrigeration system, the flow rate of the flow port 4 can be adjusted by using the electromagnet in the valve body 2 to control the raising and lowering of the valve stem, thereby controlling the pressure of the refrigeration system and protecting the normal operation of the air conditioner.

[0044] Next, with the flow port 4 in the open state, the refrigerant in the valve pipe 1 will flow from left to right. At this time, the top of the mounting ring 501 is fixedly connected to the bottom of the valve seat 3 corresponding to the flow port 4. The bottom of the mounting ring 501 is provided with a sliding cavity 502, and the inner wall of the sliding cavity 502 is slidably connected to a connecting ring 503. At the same time, the bottom of the connecting ring 503 is fixedly connected to a filter screen 504. The filter screen 504 is semi-circular in shape, and the outer wall of the filter screen 504 is provided with interception holes 505 at equal intervals. Thus, the impurity particles in the fluid can be blocked through the interception holes 505 of the filter screen 504 and intercepted outside the filter screen 504.

[0045] Next, when the refrigerant fluid flows normally through the flow port 4, a rotating rod 506 is rotatably connected to the inner wall of the cavity 7. The top of the rotating rod 506 extends through the inner wall of the through groove 8 to the inside of the filter screen 504. A turbine 507 is fixedly connected to the outer wall of the extended end of the rotating rod 506. The flow of fluid drives the turbine 507 to rotate, which in turn drives the rotating rod 506 to rotate. Then, an arc-shaped strip 508 is fixedly connected to the outer wall of the extended end of the rotating rod 506. A cleaning brush 509 is fixedly connected to the outer wall of the arc-shaped strip 508 at equal intervals to the interception hole 505. The arc-shaped strip 508 drives several cleaning brushes 509 to clean and agitate the impurities blocking the interception hole 505 from the inside of the filter screen 504, thereby clearing the filter screen 504, ensuring the flow of fluid, and thus ensuring the stable operation of the refrigeration system.

[0046] Furthermore, under normal conditions, i.e. when the filter screen 504 is less clogged, an adaptation spring 510 is provided on the inner wall of the sliding cavity 502. One end of the adaptation spring 510 is fixedly connected to the top of the connecting ring 503, and the other end of the adaptation spring 510 is fixedly connected to the inner wall of the sliding cavity 502. Thus, the elastic resistance of the adaptation spring 510 can keep the inner wall of the filter screen 504 and the cleaning brush 509 at a suitable distance. That is, the inside of the filter screen 504 and the end of the cleaning brush 509 are in contact and agitated. In this way, while maintaining a suitable cleaning and agitation effect, the friction and wear between the cleaning brush 509 and the inside of the filter screen 504 can be reduced, thereby improving the service life of this component.

[0047] As impurities gradually increase, the degree of blockage in the filter screen 504 will increase. As the number of flowable interception holes 505 decreases, the flow pressure of the fluid in the valve pipe 1 increases, thereby increasing the thrust on the filter screen 504 and causing it to rise. As the filter screen 504 rises, its interior will come into contact with and agitate the middle or even near the root of the cleaning brush 509. Compared to the agitation at the end of the cleaning brush 509, the agitation force in the middle and root of the cleaning brush 509 will be greater and stronger, thereby gradually improving the cleaning and agitation effect of the cleaning brush 509 on the interception holes 505. At the same time, the increased fluid pressure can increase the rotation speed of the turbine 507, thereby improving the cleaning and agitation efficiency of the cleaning brush 509 on the filter screen 504, so as to achieve the effect of automatically controlling the cleaning and unblocking intensity.

[0048] As the filter screen 504 gradually rises, the slide cylinder 601 will rise synchronously. During the rise of the slide cylinder 601, the cooperation between the ball bearing 9 and the spiral groove 609 allows the slide cylinder 601 to rotate synchronously during the rise. This rotation of the support plate 606 drives the three guide blocks 608 to move in a circle, and the inclined plane drives the collision column 607 to rise quickly, lifting the filter screen 504. At the same time, when it is not in contact with the guide blocks 608, the return spring 605 can drive the filter screen 504 to fall back to its original position. This allows the filter screen 504 to be continuously impacted and vibrated during the rise, which helps to improve the unblocking efficiency of the filter screen 504.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
