Description

Technical Field

[0001] The present disclosure belongs to the field of air conditioners, and particularly relates to a filter element and a subcooled liquid receiver. Background Art

[0002] A subcooled liquid receiver is a common liquid receiver and is one of the important components of an air conditioner. It is arranged on one side of the inlet end of a compressor and is used to store the unvaporized refrigerant to avoid the liquid hammer problem caused by the entry of unvaporized refrigerant into the compressor.

[0003] In the related art, in order to prevent impurities in the refrigerant from entering the compressor, a filter element is usually arranged in the tank body of the liquid receiver. When installing the filter element, the filter element is forcibly pushed into the tank body from one end of the tank body until it moves to the other end of the tank body, so that the outer flange on the outer wall of the filter element can be clamped into the groove on the inner wall of the tank body.

[0004] However, due to the narrow internal space of the tank body and the tight fit between the filter element and the tank body, it is very difficult to replace the filter element. Summary of the Invention

[0008] The hook portion is connected to the end of the first end of the core body;

[0009] The sealing ring is sleeved on the outer wall of the core body and is close to the first end of the core body;

[0013] In another implementation manner of the present disclosure, the flanging has a plurality of notches, and the notches are arranged at equal intervals along the circumferential direction of the flanging.

[0014] In yet another implementation manner of the present disclosure, the notch is triangular, and one height of the notch extends along the radial direction of the flanging and coincides with the center point of the flanging.

[0015] In yet another implementation manner of the present disclosure, the core body includes a first support plate and a second support plate, the first support plate and the second support plate are cross-connected, and the first ends of the first support plate and the second support plate extend in the same axial direction of the sealing ring to form the hook portion.

[0016] In yet another implementation manner of the present disclosure, the first support plate has hook holes near its first end, and the hook holes are respectively located on both sides of the second support plate.

[0017] In yet another implementation manner of the present disclosure, the second support plate has a support protrusion near its first end, the support protrusion extends radially outward along the sealing ring, and the orthographic projection of the support protrusion on the plane where the sealing ring is located is located inside the sealing ring.

[0018] In yet another implementation manner of the present disclosure, the outer edge of the support protrusion is arc-shaped.

[0019] In yet another implementation manner of the present disclosure, the filter element further includes a guide ring, the guide ring is sleeved on the outer wall of the core body and is located between the flanging and the sealing ring, and the orthographic projection of the guide ring on the plane where the sealing ring is located is located inside the sealing ring.

[0020] On the other hand, an embodiment of the present disclosure provides a subcooled liquid storage device, including an input port, an output port, a tank body, and the filter element according to any one of claims 1-9;

[0021] The input port and the output port are located on the tank body, and the input port and the output port are arranged at intervals along the axial direction of the tank body, and both the input port and the output port penetrate through the peripheral wall of the tank body;

[0026] That is to say, the filter element provided by the embodiment of the present disclosure can be quickly disassembled and installed in the tank body of the subcooled liquid receiver, so as to facilitate the replacement of the filter element in the subcooled liquid receiver.

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe in detail the embodiments of the present disclosure in conjunction with the accompanying drawings.

[0038] An embodiment of the present disclosure provides a filter element, which can be applied to various devices that need to filter impurities, such as the liquid reservoirs of various air conditioners. In this embodiment of the present disclosure, it is introduced by taking its application to a subcooled liquid reservoir as an example.

[0039] Figure 1 For the structural schematic diagram of this filter element, see Figure 1 , this filter element includes a filter screen 1, a hook part 2, a sealing ring 3, a flange 4, and a core body 5.

[0040] The filter screen 1 is sleeved on the core body 5 and is located between the first end and the second end of the core body 5. The hook part 2 is connected to the end of the first end of the core body 5. The sealing ring 3 is sleeved on the outer wall of the core body 5 and is close to the first end of the core body 5. The flange 4 is connected to the outer wall of the core body 5 and is close to the second end of the core body 5. The connection between the flange 4 and the core body 5 has elasticity. The end of the first end of the core body 5 has a liquid inlet 51, and the liquid inlet 51 is communicated with the inner space of the filter screen 1.

[0041] When installing the filter element provided by this embodiment of the present disclosure in the subcooled liquid reservoir, the filter element is pushed in from one end of the tank body 100 of the subcooled liquid reservoir. Since the connection between the flange 4 and the core body 5 has elasticity, during the movement of the filter element, the flange 4 will tilt adaptively away from the moving direction of the filter element to provide sufficient space for the movement of the filter element in the tank body 100, so that the filter element can move smoothly in the tank body 100 (see Figure 2 ). As the filter element moves, the filter element will move onto the installation groove 110 on the inner wall of the tank body 100. When the flange 4 passes through the installation groove 110, the flange 4 will fall into the installation groove 110 and reset under its own elasticity, so that the flange 4 is perpendicular to the moving direction of the filter element again, thereby realizing the installation of the filter element in the tank body 100 (see Figure 3 ).

[0042] When disassembling the filter element provided by the embodiment of the present disclosure in a subcooled liquid receiver, the hook is inserted into one end of the tank body 100 of the subcooled liquid receiver and hooked on the hooking part 2. Then, the filter element is pulled outwards through the hook. Since the connection between the flanging 4 and the core body 5 is elastic, during the movement of the filter element, the flanging 4 will adaptively tilt away from the moving direction of the filter element so that the flanging 4 slides out of the installation groove 110, and thus it can be smoothly disassembled from the tank body 100 (see Figure 4 ).

[0043] That is to say, the filter element provided by the embodiment of the present disclosure can be quickly disassembled and assembled in the tank body 100 of the subcooled liquid receiver, so as to facilitate the replacement of the filter element in the subcooled liquid receiver.

[0044] As can be seen from the foregoing, the flanging 4 is an important component for the filter element to be quickly replaced in the subcooled liquid receiver. Therefore, the flanging 4 will be further introduced below.

[0045] In order to ensure that the flanging 4 can swing adaptively, the material of the flanging 4 can be elastic metal, such as steel sheet, etc.

[0046] Referring again to Figure 1 , in this embodiment, the flanging 4 is an annular member, the flanging 4 extends circumferentially around the axis of the core body 5, and the outer diameter of the flanging 4 is larger than the outer diameter of the sealing ring 3.

[0047] In order to facilitate assembly, the inner walls of the tank bodies 100 of the vast majority of subcooled liquid receivers are cylindrical. Therefore, designing the flanging 4 as an annular member can make the flanging 4 applicable to the vast majority of subcooled liquid receivers to improve the applicability of the filter element. Of course, if there is a special tank body 100 with other shapes, such as square, then the flanging 4 can also be correspondingly designed as square, and the present disclosure does not limit this.

[0048] In addition, in order to ensure the filtering performance of the filter element, there must be a tight sealing fit between the outer edge of the sealing ring 3 and the inner wall of the tank body 100. In this case, since the outer diameter of the flanging 4 is larger than the outer diameter of the sealing ring 3, there is an interference fit between the outer edge of the flanging 4 and the inner wall of the tank body 100, ensuring that the outer edge of the flanging 4 is in close contact with the inner wall of the tank body 100. In this way, when the flanging 4 moves to the position of the installation groove 110, it can fall into the installation groove 110, thereby realizing the stable installation of the filter element in the tank body 100.

[0049] Of course, the outer diameter of the flanging 4 cannot be too large so as not to affect the sealing between the sealing ring 3 and the inner wall of the tank body 100. Therefore, the difference between the outer diameter of the flanging 4 and the outer diameter of the sealing ring 3 does not exceed 10 mm. In other embodiments, the difference between the outer diameter of the flanging 4 and the outer diameter of the sealing ring 3 can also be adjusted according to the actual situation, and the present disclosure does not limit this.

[0050] During the installation of the filter element, the flanging 4 swings with the connection between itself and the core body 5 as the basis. To facilitate the above-mentioned swing, in this embodiment, the flanging 4 has a plurality of notches 41, and the notches 41 are arranged at equal intervals along the circumference of the flanging 4.

[0051] It is easy to understand that since there are notches 41 on the flanging 4, the flanging 4 is equivalent to being separated into multiple small pieces. During the movement of the filter element, the small pieces are separated by the notches 41, so they swing independently and are not affected by other small pieces.

[0052] Optionally, the number of notches 41 can be selected according to actual needs. For example, it can be 3 - 5. In this embodiment, the number of notches 41 is 4. In other embodiments, it can also be other numbers, and the present disclosure does not limit this.

[0053] Exemplarily, the notch 41 is triangular, and one height of the notch 41 extends along the radial direction of the flanging 4 and coincides with the center point of the flanging 4.

[0054] That is to say, the notch 41 gradually expands from the inner edge of the flanging 4 to the outer edge of the flanging 4, which can ensure that each small piece has enough space when swinging, avoid interference between the small pieces when swinging, and improve the reliability of the filter element during disassembly and assembly.

[0055] Of course, in other embodiments, the notch 41 can also be other shapes, such as trapezoidal. When the notch 41 is trapezoidal, the top side of the trapezoid is close to the inner edge of the flanging 4, and the bottom side of the trapezoid is close to the outer edge of the flanging 4.

[0056] Figure 5 For the structural schematic diagram of the core body 5, the core body 5 will be introduced below in combination with Figure 5 Refer to

[0057] See Figure 5 , in this embodiment, the core body 5 includes a first support plate 52 and a second support plate 53. The first support plate 52 and the second support plate 53 are cross - connected, and the first ends of the first support plate 52 and the second support plate 53 extend in the same axial direction of the sealing ring 3 to form the hook - mounting part 2.

[0058] In the above implementation, the cross - connected first support plate 52 and second support plate 53 can make the core body 5 form a stable structure, ensuring the structural strength and structural stability of the core body 5. Moreover, since the hook - mounting part 2 is formed by the extension of the first ends of the first support plate 52 and the second support plate 53, the hook - mounting part 2 and the first support plate 52 and the second support plate 53 are of an integral structure. In this way, when disassembling the filter element, it is beneficial for the hook - mounting part 2 to apply a pulling force to the core body 5 to more smoothly achieve the disassembly of the filter element.

[0059] Optionally, both the first support plate 52 and the second support plate 53 are rectangular plates. The first end and the second end of the first support plate 52, and the first end and the second end of the second support plate 53 are respectively the two ends in their respective length directions. The first ends of the first support plate 52 and the second support plate 53 extend in the same direction, and the second ends of the first support plate 52 and the second support plate 53 extend in the same direction.

[0060] Optionally, the first support plate 52 and the second support plate 53 are perpendicular to each other, so that the cross-connected first support plate 52 and second support plate 53 form a cross-shaped structural member. Moreover, the distances from the first support plate 52 to the two long sides of the second support plate 53 are equal, and the distances from the second support plate 53 to the two long sides of the first support plate 52 are equal, which can further ensure the structural strength and structural stability of the core body 5.

[0061] In order to improve the structural stability of the core body 5, in this embodiment, the core body 5 further includes an end plate 54. The end plate 54 is perpendicular to the length directions of the first support plate 52 and the second support plate 53 and is connected to the second ends of the first support plate 52 and the second support plate 53.

[0062] In the above implementation manner, the end plate 54 is used to fix the second ends of the first support plate 52 and the second support plate 53, making the first support plate 52 and the second support plate 53 more stable and improving the reliability of the filter element.

[0063] Optionally, the end plate 54 can be circular, and the outer edge of the end plate 54 is flush with the outer sides of the first support plate 52 and the second support plate 53 to better match the cross-shaped first support plate 52 and second support plate 53 connected together. Of course, the end plate 54 can also be designed into other shapes according to actual needs, such as a quadrilateral, etc., and the present disclosure does not limit this.

[0064] When there is an end plate 54 at the second ends of the first support plate 52 and the second support plate 53, the flanging 4 is circumferentially connected to the outer edge of the end plate 54, that is, the inner edge of the flanging 4 is connected to the outer edge of the end plate 54. At this time, the end plate 54 is used to provide an installation base for the flanging 4, so that the flanging 4 can be stably installed on the core body 5 through the end plate 54, ensuring that the flanging 4 can stably realize the installation between the filter element and the tank body 100.

[0065] As can be seen from the foregoing, when disassembling the filter element, it is necessary to use a hook to pull the filter element outwards. Then, in order to achieve a stable hook between the hook and the hook portion 2, in this embodiment, the first support plate 52 has a hook hole 21 near its first end, and the hook holes 21 are respectively located on both sides of the second support plate 53.

[0066] In the above implementation, the hook holes 21 are used to receive the hooks. When disassembling the filter element, the hook is inserted into one end of the tank body 100 until the hook catches the hook hole 21, and then the hook is pulled to move the entire filter element outward by the hook portion 2, thereby realizing the disassembly of the filter element.

[0067] Moreover, since the hook holes 21 are respectively located on both sides of the second support plate 53, the hook can catch the hook holes 21 from both sides of the second support plate 53, reducing the operation difficulty of disassembling the filter element.

[0068] It is easy to understand that in order to more conveniently catch the hook hole 21, the size of the hook hole 21 can be designed as large as possible, but it should not affect the structural strength of the hook portion 2. Figure 6 is the front view of the core body 5, combined with Figure 6 , to achieve the above effect, the hook hole 21 is a strip-shaped hole, and the length direction of the hook hole 21 is the same as the length direction of the first support plate 52, so as to avoid the first end of the first support plate 52 being weak due to the outer edge of the end of the hook hole 21 being too close to the first end edge of the first support plate 52. For the same reason, the hook hole 21 is arranged close to the second support plate 53, that is, close to the middle of the first support plate 52, so as to avoid the side edge of the first support plate 52 being weak due to the outer edge of the side of the hook hole 21 being too close to the side edge of the first support plate 52.

[0069] Next, continue to combine Figure 5 to introduce the core body 5.

[0070] In this embodiment, the core body 5 further includes a support ring 55. The support ring 55 is sleeved on the first support plate 52 and the second support plate 53 near the first end, and the axis of the support ring 55 is parallel to the length direction of the first support plate 52.

[0071] In the above implementation, the support ring 55 is used to fix the first ends of the first support plate 52 and the second support plate 53, making the first support plate 52 and the second support plate 53 more stable and improving the reliability of the filter element.

[0072] When there is a support ring 55 at the first ends of the first support plate 52 and the second support plate 53, the sealing ring 3 is coaxially sleeved on the support ring 55, that is, the inner edge of the sealing ring 3 is connected to the outer edge of the support ring 55. At this time, the support ring 55 is used to provide an installation base for the sealing ring 3, so that the sealing ring 3 can be stably installed on the core body 5 through the support ring 55, ensuring that the sealing ring 3 can achieve good sealing.

[0073] In this embodiment, the second support plate 53 has a support protrusion 56 near its first end. The support protrusion 56 extends radially outward along the sealing ring 3, and the orthographic projection of the support protrusion 56 on the plane where the sealing ring 3 is located is within the sealing ring 3.

[0074] In the above implementation, the support protrusion 56 is used to support the first end of the core body 5 to avoid unnecessary shaking during the movement of the core body 5 within the tank 100. Moreover, since the orthographic projection of the support protrusion 56 on the plane where the sealing ring 3 is located is within the sealing ring 3, the support protrusion 56 does not protrude beyond the outer edge of the sealing ring 3, thus ensuring that the support protrusion 56 does not affect the sealing effect of the sealing ring 3 and improving the reliability of the filter element.

[0075] Optionally, the outer edge of the support protrusion 56 is arc-shaped.

[0076] As can be seen from the foregoing, the inner walls of the tanks 100 of the vast majority of subcooled liquid storage devices are cylindrical. Therefore, designing the outer edge of the support protrusion 56 to be arc-shaped can enable the support protrusion 56 to be applicable to the vast majority of subcooled liquid storage devices to improve the applicability of the filter element. Of course, if there is a special tank 100 with other shapes, such as square, then the outer edge of the support protrusion 56 can also be correspondingly designed to be square, and the present disclosure does not limit this.

[0077] In addition, the number of the support protrusions 56 can be adjusted according to actual needs. For example, when the axial length of the filter element is relatively large, a larger number of support protrusions 56 can be configured to enable the filter element to move smoothly. When the axial length of the core body 5 is relatively small, a smaller number of support protrusions 56 can be configured to reduce the manufacturing cost of the filter element.

[0078] A plurality of support protrusions 56 are respectively located on both side edges of the second support plate 53, and the support protrusions 56 are arranged in sequence along the length direction of the second support plate 53, thereby ensuring the stable support of the support protrusions 56 for the filter element. Moreover, in order to further improve the supporting ability of the support protrusions 56 for the filter element, the support protrusions 56 located on both side edges of the second support plate 53 are symmetrically arranged with respect to the first support plate 52.

[0079] It can be seen that the support protrusions 56 provide good support for the first end of the core body 5. In order to further ensure the stability of the filter element during movement, a guide ring is also configured in the filter element provided in the embodiment of the present disclosure to support the middle part of the filter element.

[0080] In this embodiment, the filter element further includes a guide ring 6. The guide ring 6 is sleeved on the outer wall of the core body 5 and is located between the flanging 4 and the sealing ring 3. The orthographic projection of the guide ring 6 on the plane where the sealing ring 3 is located is within the sealing ring 3.

[0081] In the above implementation, the outer edge of the guiding ring 6 is used for sliding cooperation with the inner wall of the tank body 100, so as to guide and support the middle part of the filter element. Since the orthographic projection of the guiding ring 6 on the plane where the sealing ring 3 is located is within the sealing ring 3, the guiding ring 6 will not protrude beyond the outer edge of the sealing ring 3, thus ensuring that the guiding ring 6 will not affect the sealing effect of the sealing ring 3 and improving the reliability of the filter element.

[0082] Optionally, the guiding ring 6 includes a square main body frame 61, and the four outer corners 62 of the main body frame 61 are arc corners for sliding cooperation with the inner wall of the tank body 100. For the same reason as that of the supporting protrusion 56, designing the four outer corners 62 of the main body frame 61 as arc corners can make the guiding ring 6 applicable to most subcooled liquid storage devices, so as to improve the applicability of the filter element. Of course, if there is a special tank body 100 with other shapes, such as square, then the four outer corners 62 of the main body frame 61 can also be correspondingly designed as square, and the present disclosure does not limit this.

[0083] In addition, since the main body frame 61 is square, when the four outer corners 62 slide in contact with the inner wall of the tank body 100, an overflow gap can be formed between the part of the main body frame 61 between two adjacent outer corners 62 and the inner wall of the tank body 100. This overflow gap is used for the refrigerant to flow through.

[0084] In other embodiments, the main body frame 61 can also be a polygon with other shapes, such as a triangle, a pentagon, etc. When the main body frame 61 is a triangle, the three outer corners 62 of the main body frame 61 are arc corners; when the main body frame 61 is a pentagon, the five outer corners 62 of the main body frame 61 are arc corners. The present disclosure does not limit this. It is easy to understand that on the basis of ensuring that the outer corners 62 of the main body frame 61 can slide in cooperation with the inner wall of the tank body 100, the more the outer corners 62 of the main body frame 61 are, the smaller the overflow gap formed between it and the inner wall of the tank body 100 is. Therefore, in order to ensure the normal circulation of the refrigerant, the number of the outer corners 62 of the main body frame 61 does not exceed 6.

[0085] The embodiment of the present disclosure also provides a subcooled liquid storage device, see Figure 7 , this subcooled liquid storage device includes an input port 200, an output port 300, a tank body 100 and Figure 1 the filter element shown.

[0086] The input port 200 and the output port 300 are located on the tank body 100, and the input port 200 and the output port 300 are arranged at intervals along the axial direction of the tank body 100, and both the input port 200 and the output port 300 penetrate through the peripheral wall of the tank body 100.

[0087] The inner diameter of the tank body 100 is not greater than the outer diameter of the sealing ring 3. An annular mounting groove 110 is provided on the inner peripheral wall of the tank body 100. The mounting groove 110 is arranged circumferentially around the axis of the tank body 100. The mounting groove 110 is used to accommodate the flanging 4. When the flanging 4 is inserted into the mounting groove 110, the sealing ring 3 is located between the input port 200 and the output port 300. The input port 200, the liquid inlet 51, the inner space of the filter screen 1, the outer space of the filter screen 1, and the output port 300 are communicated in sequence.

[0088] When installing the filter element provided in the embodiment of the present disclosure in the subcooled liquid storage device, the filter element is pushed into one end of the tank body 100 of the subcooled liquid storage device. Since the connection between the flanging 4 and the core body 5 is elastic, during the movement of the filter element, the flanging 4 will adaptively tilt away from the moving direction of the filter element to provide sufficient space for the movement of the filter element in the tank body 100, so that the filter element can move smoothly in the tank body 100 (see Figure 2 ). As the filter element moves, the filter element will move onto the mounting groove 110 on the inner wall of the tank body 100. When the flanging 4 passes through the mounting groove 110, the flanging 4 will fall into the mounting groove 110 and reset under its own elasticity, so that the flanging 4 is perpendicular to the moving direction of the filter element again, thereby realizing the installation of the filter element in the tank body 100 (see Figure 3 ).

[0089] When disassembling the filter element provided in the embodiment of the present disclosure from the subcooled liquid storage device, the hook is inserted into one end of the tank body 100 of the subcooled liquid storage device and hooked on the hooking portion 2. Then, the filter element is pulled outwards through the hook. Since the connection between the flanging 4 and the core body 5 is elastic, during the movement of the filter element, the flanging 4 will adaptively tilt away from the moving direction of the filter element, so that the flanging 4 slides out of the mounting groove 110, and thus can be smoothly disassembled from the tank body 100 (see Figure 4 ).

[0090] That is to say, the filter element provided in the embodiment of the present disclosure can be quickly disassembled and installed in the tank body 100 of the subcooled liquid storage device, so as to facilitate the replacement of the filter element in the subcooled liquid storage device.

[0091] Next, in conjunction with Figure 7 , a brief introduction to the working process of the subcooled liquid storage device provided in the embodiment of the present disclosure is given:

[0092] As shown by the arrow, the coolant enters the tank body 100 through the input port 200 on the tank body 100. The coolant in the tank body 100 enters the inner space of the filter screen 1 through the liquid inlet 51 of the filter element. Then, the coolant passes through the filter screen 1 to flow to the outer space of the filter screen 1. During this process, the refrigerant is filtered through the filter screen 1. Finally, the refrigerant in the outer space of the filter screen 1 flows out through the output port 300 on the tank body 100.

[0093] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present disclosure shall be included within the protection scope of the present disclosure.
