As shown in connection with fig. 1-5, an embodiment of the present disclosure provides an electronic expansion valve assembly 100 comprising an electronic expansion valve, a throttling element 20, and a filter 30.

The electronic expansion valve comprises a valve core 10, one end of a throttling element 20 is connected with the valve core 10, and the opening degree of the electronic expansion valve is controlled through the valve core 10.

The other end of the throttling element 20 is connected with the filter 30, and the filter 30 can block impurities in the refrigerant circulation loop so that the impurities cannot pass through, thereby preventing dirty blockage in the refrigerant circulation loop.

As shown in fig. 5, taking an example of an application of the electronic expansion valve assembly 100 to an air conditioner, the air conditioner includes an indoor unit including an indoor heat exchanger 80 and an outdoor unit including an outdoor heat exchanger 90, and the electronic expansion valve assembly 100 is connected between the indoor heat exchanger 80 and the outdoor heat exchanger 90.

As shown in fig. 5, the air conditioner further includes a compressor 60, the compressor 60 is disposed in the outdoor unit, and the compressor 60, the indoor heat exchanger 80, the electronic expansion valve assembly 100 and the outdoor heat exchanger 90 are connected to form a refrigerant circulation loop, so as to implement cooling and heating functions of the air conditioner.

As shown in fig. 1 to 4, the electronic expansion valve assembly 100 further includes a sleeve assembly 40, and the sleeve assembly 40 is at least partially sleeved outside a connection portion between the other end of the throttling element 20 and the filter 30.

In the embodiment, the sleeve assembly 40 is at least partially sleeved outside the joint of the throttling element 20 and the filter 30, and the sleeve assembly 40 can circumferentially share the force borne by the joint of the throttling element 20 and the filter 30, so that the force borne by the joint of the throttling element 20 and the filter 30 is reduced. Thereby preventing the electronic expansion valve assembly 100 from being subjected to a risk of breakage due to longitudinal vibration and circumferential inclination during transportation.

In the related art, in order to prevent the connection between the throttling element 20 and the filter 30 from being broken, the throttling element 20 is generally thickened or the throttling element 20 is integrally formed by stretching. However, although the risk of breakage of the connection between the throttling element 20 and the filter 30 is reduced, the opening range of the electronic expansion valve is affected, and when the electronic expansion valve assembly 100 is applied to an air conditioner, abnormal noise of refrigerant flow is generated when an indoor unit operates, and the use effect is affected.

With the electronic expansion valve assembly 100 of the present embodiment, the structures of the throttling element 20 and the filter 30 do not need to be changed, and the opening degree of the electronic expansion valve is not affected, so that the throttling and sound effects of the throttling element 20 can be retained.

The sleeve assembly 40 at least partially covers the outside of the connection between the other end of the throttling element 20 and the filter 30: the sleeve assembly 40 may be completely sleeved outside the connection between the other end of the throttling element 20 and the filter 30, or the sleeve assembly 40 may be partially sleeved outside the connection between the other end of the throttling element 20 and the filter 30.

Alternatively, the throttling element 20 comprises a capillary tube, which may significantly reduce the cost of the throttling element 20.

It will be appreciated that the throttling element 20 may take other forms than a capillary tube, such as a manual expansion valve, a ball float expansion valve, or a thermostatic expansion valve.

Alternatively, as shown in fig. 3, the sleeve assembly 40 includes a rubber pad 50 and a sheath 502, the rubber pad 50 being sleeved outside the other end of the throttling element 20; one end of the sheath 502 is connected to the rubber pad 50 and at least partially covers the outside of the connection between the other end of the throttling element 20 and the filter 30.

In this embodiment, the rubber pad 50 has elasticity, and can buffer the force applied to the throttling element 20 in the circumferential direction, and prevent the throttling element 20 from being broken by the force inclined in the circumferential direction. One end of the sheath 502 is connected with the rubber pad 50 and sleeved outside the joint of the other end of the throttling element 20 and the filter 30, so as to further protect the joint of the throttling element 20 and the filter 30 in the circumferential direction, buffer the force applied to the joint in the circumferential direction and avoid the joint from being broken due to circumferential inclination.

The rubber pad 50 is annular so that the rubber pad 50 can cushion the force received by the throttling element 20 from the circumferential direction. The jacket 502 is also annular in shape to allow the jacket 502 to cushion forces experienced at the junction of the other end of the throttling element 20 and the filter 30.

When the electronic expansion valve assembly 100 is used in an air conditioner, the electronic expansion valve assembly 100 is disposed in an outdoor unit, and the electronic expansion valve assembly 100 is generally in a vertical state when in use. The spool 10, the throttling element 20, and the filter 30 are sequentially disposed in this order from top to bottom.

Optionally, the shroud assembly 40 extends in a vertical direction so as to fit over the connection of the other end of the restriction element 20 and the filter 30.

Optionally, the rubber pad 50 is disposed in a vertical direction with the sheath 502, specifically, the rubber pad 50 is located above the sheath 502.

Due to the connection of the rubber pad 50 and the sheath 502, the rubber pad 50 can share the longitudinal force applied to the sheath 502, so that the longitudinal force applied to the joint of the throttling element 20 and the filter 30 is reduced, the impact force of the longitudinal vibration force on the joint is reduced, and the joint is prevented from being broken due to the longitudinal vibration force.

Optionally, the sheath 502 extends in a direction from the throttling element 20 to the filter 30, and after the sheath 502 passes over the outside where the other end of the throttling element 20 is connected to the filter 30, the other end of the sheath 502 is sleeved outside the filter 30 and connected to the filter 30.

In this embodiment, the sheath 502 is extended over the outside of the junction of the other end of the restriction member 20 and the filter 30, and the other end of the sheath 502 is connected to the outside of the filter 30, thereby increasing the area of the sheath 502 around the outside of the restriction member 20 and the filter 30. That is, the sheath 502 not only circumferentially protects the connection between the other end of the restriction element 20 and the filter 30 (hereinafter, collectively referred to as the connection), but also further protects the connection in the longitudinal direction, thereby enabling greater sharing of the force received at the connection between the restriction element 20 and the filter 30.

In the case where the restrictive element 20 and filter 30 extend in a vertical direction, the sheath 502 extends in a vertical direction as well to increase the area of the sheath 502 that fits over the outside of the restrictive element 20 and filter 30.

Optionally, one end of the sheath 502 is sleeved outside the rubber pad 50; one of the inner wall surface of one end of the sheath 502 and the outer wall surface of the rubber pad 50 is provided with a groove 501, the other of the inner wall surface of one end of the sheath 502 and the outer wall surface of the rubber pad 50 is provided with a first protrusion 5021 matched with the groove 501, and when one end of the sheath 502 is connected with the rubber pad 50, the first protrusion 5021 is located in the groove 501.

In this embodiment, one end of the sheath 502 is sleeved outside the rubber pad 50, that is, the inner diameter of one end of the sheath 502 is greater than or equal to the outer diameter of the rubber pad 50, so that the sheath 502 is conveniently sleeved outside the rubber pad 50. One end of the sheath 502 is connected with the rubber pad 50 through the groove 501 and the first protrusion 5021, so that the processing is convenient, the cost is low, and the connection between the sheath 502 and the rubber pad 50 is more stable.

In a specific embodiment, an inner wall surface of one end of the sheath 502 is provided with a first protrusion 5021, an outer wall surface of the rubber pad 50 is provided with a groove 501, wherein the first protrusion 5021 extends along the circumferential direction of the sheath 502, the groove 501 extends along the circumferential direction of the rubber pad 50, and the first protrusion 5021 is matched with the groove 501.

Since the inner diameter of one end of the sheath 502 is greater than or equal to the outer diameter of the rubber pad 50, the one end of the sheath 502 is provided with a first opening so that the rubber pad 50 penetrates into the sheath 502 through the first opening.

Optionally, a first protrusion 5021 is formed by extending a side wall of the sheath 502 corresponding to the first opening toward the inside, and when one end of the sheath 502 is connected with the rubber pad 50, the first protrusion 5021 is located inside the groove 501. This reduces the material of the sheath 502, reduces the cost, increases the aesthetic appeal, and facilitates handling the rubber pad 50 in connection with the sheath 502.

It can be understood that the inner wall surface of one end of the sheath 502 may also be provided with a groove 501, and the outer wall surface of the rubber pad 50 is provided with a first protrusion 5021, wherein the groove 501 extends along the circumferential direction of the sheath 502, the first protrusion 5021 extends along the circumferential direction of the rubber pad 50, and the first protrusion 5021 is also matched with the groove 501.

Optionally, the part of the outer wall surface of the throttling element 20 inside the sheath 502 protrudes outwards to form a second protrusion 203, and the second protrusion 203 abuts against the rubber pad 50.

In the present embodiment, the throttling element 20 forms the second protrusion 203, and the second protrusion 203 abuts against the rubber pad 50, on one hand, the second protrusion 203 can prevent the rubber pad 50 from moving; on the other hand, the sectional area of the second protrusion 203 is larger, so that the contact area between the throttling element 20 and the rubber pad 50 is increased, and when the throttling element 20 is stressed, the rubber pad 50 can share more force, so as to further avoid the fracture of the joint of the throttling element 20 and the filter 30.

Optionally, the second protrusion 203 extends in the circumferential direction of the throttling element 20.

In this embodiment, the second protrusion 203 extends in the circumferential direction of the throttling element 20, so that the contact area between the second protrusion 203 and the rubber pad 50 in the circumferential direction is increased, the sharing force of the rubber pad 50 on the second protrusion 203 is more uniform, and the fracture at the joint between the throttling element 20 and the filter 30 caused by the uneven force or force applied to the throttling element 20 is avoided.

Optionally, the second protrusion 203 is annular, so as to further increase the contact area between the rubber pad 50 and the second protrusion 203.

Optionally, second projection 203 is in an upset configuration.

In the present embodiment, the upset structure is a forging step for enlarging the cross section of the billet. When the local cross section of the billet is increased, the local upset is called local upsetting. In this embodiment, localized upset is applied to the throttling element 20, which upset acts to improve the transverse mechanical properties of the forging and reduce anisotropy.

Optionally, the length of rubber pad 50 extending outside of sheath 502 is greater than the length of rubber pad 50 within sheath 502.

In this embodiment, the length of the rubber pad 50 extending out of the sheath 502 is greater than the length of the rubber pad 50 located in the sheath 502, so that on one hand, the space occupied by the rubber pad 50 in the sheath 502 can be reduced, and sufficient space for the arrangement of the second protrusion 203 and the connection between the throttling element 20 and the filter 30 can be ensured. On the other hand, the length of the rubber pad 50 can be increased, and since the rubber pad 50 is sleeved outside the throttling element 20, the length of the rubber pad 50 is longer, so that the circumferential direction of the throttling element 20 can be protected, the circumferential force of the throttling element 20 can be shared, and the risk of fracture of the other end of the throttling element 20 and the filter 30 can be reduced.

Alternatively, the outer wall surface 5022 of the other end of the sheath is inclined toward the inside in the direction from the throttle element 20 to the filter 30.

In this embodiment, the outer wall 5022 at the other end of the sheath is inclined, which can reduce the diameter of the other end of the sheath 502, reduce the production cost of the sheath 502, and facilitate the installation of the electronic expansion valve assembly 100.

When the orifice element 20 and the filter 30 are vertically disposed, since both the refrigerant flows through the orifice element 20 and the filter 30, condensed water is easily generated on the outer wall surface of the sheath 502 even when the temperature of the refrigerant changes. The outer wall surface of the other end of the sheath 502 is connected to the outer wall surface of the filter 30 by slant filtration. When condensed water exists on the outer wall surface of the sheath 502, the condensed water can flow down along the inclined surface under the action of gravity.

Alternatively, as shown in FIG. 4, the other end of the throttling element 20 is located inside the filter 30; one of the outer wall surface of the other end of the throttling element 20 and the inner wall surface of the filter 30 is provided with a limiting part, the other of the outer wall surface of the other end of the throttling element 20 and the inner wall surface of the filter 30 is provided with a limiting matching part matched with the limiting part, and when the other end of the throttling element 20 is connected with the filter 30, the limiting part is matched with the limiting matching part.

In this embodiment, the depth of the other end of the throttling element 20 inserted into the filter 30 can be ensured through the limiting part and the limiting matching part, so that the other end of the throttling element 20 is stably connected with the filter 30, the flowing of the refrigerant in the throttling element 20 and the filter 30 is further ensured, and the refrigerant is prevented from overflowing.

Optionally, one of the limiting part and the limiting matching part comprises a limiting protrusion 204, the other of the limiting part and the limiting matching part comprises a limiting groove, and the limiting protrusion 204 and the limiting groove are simple in structure, so that the other end of the throttling element 20 can be effectively connected with the filter 30 in place.

Optionally, the other end of the throttling element 20 is fixedly connected to the filter 30.

Through fixed connection, can further guarantee the stability of being connected of throttling element 20 and filter 30 junction, improve the atress condition of junction, avoid the junction fracture.

The other end of the restriction member 20 is welded to the filter 30, but may be attached in other ways, such as by adhesive bonding.

The electronic expansion valve assembly 100 is integrated by inserting the filter 30 and the valve cartridge 10 into the restriction member 20 and welding the filter 30 and the valve cartridge 10 to each other.

Optionally, the other end of the sheath 502 is fixedly attached to the filter 30.

Through fixed connection, can guarantee the connection stability of throttling element 20 and filter 30 junction, improve the atress condition of junction, avoid the junction fracture. Moreover, since one end of the sheath 502 is connected with the rubber pad 50, the rubber pad 50 abuts against the second protrusion 203, and the other end of the sheath 502 is fixedly connected with the filter 30, one end of the sheath 502 can press the rubber pad 50, which can alleviate the impact of the longitudinal vibration on the connection between the other end of the throttling element 20 and the filter 30.

Optionally, an end of the filter 30 facing away from the throttling element 20 is provided with a refrigerant outlet to facilitate outflow of the refrigerant.

Alternatively, the throttling element 20 includes a first throttling element 201 and a second throttling element 202, and one end of the first throttling element 201 and one end of the second throttling element 202 are both connected to the spool 10.

The filter 30 includes a first filter 301 and a second filter 303.

One end of the first filter 301 is connected to the other end of the first throttling element 201, and the first filter 301 can block impurities in the refrigerant circulation circuit so that the impurities cannot pass through, thereby preventing dirty blocking in the refrigerant circulation circuit. Similarly, one end of the second filter 303 is connected to the other end of the second throttling element 202, and the second filter 303 can block impurities in the refrigerant circulation circuit so that the impurities cannot pass through, thereby preventing dirty blocking in the refrigerant circulation circuit.

The sleeve assemblies 40 are equal in number and correspond one-to-one to the throttling elements 20. The shroud assembly 40 includes a first shroud assembly 401 and a second shroud assembly 402, the first shroud assembly 401 at least partially surrounds a connection between the other end of the first throttling element 201 and the first filter 301, and the second shroud assembly 402 at least partially surrounds a connection between the other end of the second throttling element 202 and the second filter 303.

Taking the electronic expansion valve assembly 100 as an example of an application to an air conditioner, in a usage state of the electronic expansion valve, the first filter 301 is located below the first throttling element 201, and the second filter 303 is located below the second throttling element 202.

In the cooling mode and the heating mode of the air conditioner, the flow directions of the refrigerant in the refrigerant circulation circuit are different, taking as an example that the refrigerant sequentially flows through the first filter 301, the first throttling element 201, the second throttling element 202 and the second filter 303 in the electronic expansion valve assembly 100 in the cooling mode, the refrigerant sequentially flows through the second filter 303, the second throttling element 202, the first throttling element 201 and the first filter 301 in the electronic expansion valve assembly 100 in the heating mode.

Taking the example that the refrigerant sequentially flows through the second filter 303, the second throttling element 202, the first throttling element 201 and the first filter 301 in the electronic expansion valve assembly 100 in the heating mode, the refrigerant is pressurized by the compressor 60 to become high-temperature high-pressure gas, and the high-temperature high-pressure gas enters the indoor heat exchanger 80 after passing through the four-way reversing valve 70, is condensed, liquefied and released heat to become high-pressure normal-temperature liquid, and heats indoor air at the same time, so that the purpose of increasing the indoor temperature is achieved. The refrigerant passes through the second throttling element 202 and the valve core 10 in sequence to be throttled and decompressed to become low-pressure low-temperature liquid, enters the outdoor heat exchanger 90, is evaporated to absorb heat to become gas, absorbs heat of outdoor air to become gaseous refrigerant, and enters the compressor 60 again to start the next cycle.

As shown in fig. 5, an embodiment of the present disclosure further provides an air conditioner including an indoor unit, an outdoor unit, and the electronic expansion valve assembly 100 according to any one of the above embodiments.

The air conditioner provided by the embodiment of the present disclosure includes the electronic expansion valve assembly 100 in any one of the above embodiments, so that all the beneficial effects of the electronic expansion valve assembly 100 in any one of the above embodiments are achieved, and details are not repeated herein.
