Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and particularly relates to a distributor for an air conditioner. Background Art

[0002] The distributor is widely used in the pipeline of the air conditioner and is used to shunt the refrigerant in the pipeline. It has an inlet end and at least two outlet ends. The refrigerant flows into the refrigerant distributor from the inlet end, is fully mixed, and then flows out from at least two outlet ends, so as to realize the shunt after the refrigerant is evenly mixed. In the related art, when distributing multiple flow paths, a distributor is usually used to distribute the flow paths. In order to avoid system blockage affecting the uniformity of distribution, a filter is usually welded at the upstream end of the distributor. However, adding a filter at the upstream end of the distributor will increase the processing time and processing cost. Moreover, the welding process is also prone to problems such as welding blockage, welding slag, and welding tumors.

[0003] The existing Chinese utility model patent with the application number 202322000891.8 discloses an air conditioner distributor, including: a distributor body, which is composed of an integrally formed liquid inlet part and a shunt part, has high structural strength and a long service life. An inlet channel is arranged in the liquid inlet part, a shunt cavity communicated with the inlet channel is arranged in the shunt part, and a shunt component is arranged in the shunt cavity to achieve the effect of evenly distributing the refrigerant. A plurality of shunt channels communicated with the shunt cavity are arranged at one end of the shunt part far away from the liquid inlet part. The above-mentioned existing air conditioner distributor also discloses a filter component, including a filter screen. However, the filtering effect of the flat filter screen is limited, and after long-term use, even if structures such as fan blades are used for cleaning, impurities will still accumulate at the filter screen, causing the filter screen to be blocked and affecting the liquid flow in the distributor. Summary of the Utility Model

[0004] In view of this, the utility model aims to provide a distributor for an air conditioner to solve the problem that impurities are likely to accumulate at the flat filter screen in the existing air conditioner distributor, affecting the liquid flow in the distributor.

[0005] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] A distributor for an air conditioner comprises a shell, one end of the shell is provided with an inlet, the other end is provided with an outlet, at least two outlets are provided, a filter assembly is provided at a position on the shell corresponding to one end of the inlet; the filter assembly comprises a limiter and a filter basket, one end of the filter basket is provided with a positioning ring, and the other end extends into the shell, and a protrusion cooperating with the positioning ring is provided at a position on the shell corresponding to one end of the inlet; the end of the limiter extending into the filter basket is provided with a limit plate for limiting the filter basket, and the other end is provided with a limit ring for limiting the positioning ring, a through hole is provided between the limiter and the limit ring for facilitating the passage of liquid, a conical air guide cover is provided on the limiter at a position corresponding to between the limit ring and the limit plate, the conical end of the air guide cover is arranged toward the limit ring, and a passing gap is provided between the air guide cover and the inner wall of the filter basket.

[0007] Furthermore, the limiting member and the limiting ring are connected via a connecting strip.

[0008] Furthermore, at least two connecting strips are evenly arranged along the circumference of the limiting member, and there is a liquid-passing gap between two adjacent connecting strips.

[0009] Furthermore, the connecting strip is obliquely arranged on the limiting member.

[0010] Furthermore, the end of the limiting ring facing the filter basket is provided with a protrusion that can cooperate with the inner side of the filter basket.

[0011] Furthermore, there is a receiving gap between the air guide cover and the limiting plate for receiving impurities, the receiving gap is connected with the passing gap, and a receiving groove connected with the receiving gap is provided on the side of the air guide cover facing the limiting plate.

[0012] Furthermore, a limiting groove cooperating with the filter basket is provided at a position corresponding to one end of the outlet on the shell.

[0013] Compared with the prior art, the air conditioner distributor described in the utility model has the following advantages:

[0014] (1) The air conditioner distributor described in the utility model has the advantages of simple structure, easy assembly and use, good diversion effect, and not easy to be blocked. By arranging a limit plate on the limit member and using the limit plate to support the inner side of the filter basket, the filter basket can be effectively limited, which is conducive to preventing the filter basket from being deformed during installation or use, and ensuring that the filter assembly can continuously and stably filter the liquid entering the distributor.

[0015] (2) For a distributor for an air conditioner according to the present utility model, by providing a conical flow guide cover on the limiting member, the liquid entering through the housing inlet can flow towards the outlets around under the guidance of the flow guide cover. The flow guide cover can play a good role in diverting and guiding the refrigerant, guiding the refrigerant to flow quickly towards the outlets on the housing, which is beneficial to improving the distribution effect of this distributor. At the same time, by providing a receiving groove communicating with the receiving gap on one side of the flow guide cover facing the limiting plate, the impurities moving downward along the surface of the flow guide cover to the gap between the flow guide cover and the limiting plate can be collected in the receiving gap and the receiving groove. Since the flow guide cover can play a good shielding role, the impurities are less likely to be driven and diffused by the liquid flow, thereby reducing the possibility of the impurities blocking the filter basket.

[0016] (3) For a distributor for an air conditioner according to the present utility model, by using a plurality of connecting strips to connect the limiting member and the limiting ring, it is beneficial to improve the structural strength of the connection between the limiting member and the limiting ring, thereby ensuring that the limiting member can continuously and stably limit the filter basket. At the same time, by arranging the connecting strips obliquely on the limiting member, when the refrigerant entering through the housing inlet flows through the limiting ring, it will flow and disperse along the obliquely arranged connecting strips, thereby forming a spiral flowing liquid flow in the filter basket. Then, under the guidance of the flow guide cover, it can be more quickly and evenly distributed to each outlet through the filter basket. In addition, the spiral flowing liquid flow can also make the impurities in the liquid move away from the filter basket under the action of centrifugal force, and finally move downward along the surface of the flow guide cover to the gap between the flow guide cover and the limiting plate for collection, and the impurities are less likely to accumulate on the inner wall of the filter basket.

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] A distributor for an air conditioner, as Figures 1 to 5As shown, it includes a shell 1, one end of which is provided with an inlet, and the other end is provided with an outlet 2, at least two of which are provided, and a filter assembly is provided at a position corresponding to one end of the inlet on the shell 1; the filter assembly includes a stopper 13 and a filter basket 3, one end of the filter basket 3 is provided with a positioning ring 4, and the other end extends into the shell 1, and a protrusion 7 cooperating with the positioning ring 4 is provided at a position corresponding to one end of the inlet on the shell 1; the end of the stopper 13 extending into the filter basket 3 is provided with a stopper plate 11 for limiting the filter basket 3, and the other end is provided with a stopper ring 5 for limiting the positioning ring 4, a through hole is provided between the stopper 13 and the stopper ring 5 for facilitating the passage of liquid, a conical flow guide cover 9 is provided at a position corresponding to between the stopper ring 5 and the stopper plate 11 on the stopper 13, the conical end of the flow guide cover 9 is arranged toward the stopper ring 5, and a passing gap is provided between the flow guide cover 9 and the inner wall of the filter basket 3.

[0030] Exemplarily, the housing 1 and the filter basket 3 are cylindrical structural members, and the two are coaxially arranged. Correspondingly, the limiting plate 11 is also a circular structural member. By arranging the limiting plate 11 on the limiting member 13 and using the limiting plate 11 to support the inner side of the filter basket 3, the filter basket 3 can be effectively limited, which is conducive to preventing the filter basket 3 from being deformed during installation or use, and ensuring that the filter assembly can continuously and stably filter the liquid entering the dispenser.

[0031] In actual application, the operator can first install the filter basket 3 in the housing 1, and use the protrusion 7 in the housing 1 to cooperate with the positioning ring 4 on the filter basket 3 to limit the filter basket 3. After that, the operator can insert the limiting member 13 into the filter basket 3, use the limiting plate 11 on the limiting member 13 to support the bottom of the filter basket 3, and use the limiting ring 5 on the limiting member 13 to support the positioning ring 4 of the filter basket 3, so as to achieve stable assembly of the filter basket 3 on the housing 1, which is easy to operate and is conducive to improving the stability of the filter basket 3 in the housing 1.

[0032] Optionally, the limiting member 13 is connected to the limiting ring 5 via a connecting strip 12. Exemplarily, one end of the connecting strip 12 is fixed to the limiting member 13, and the other end is fixed to the limiting ring 5, and the air guide cover 9 and the limiting plate 11 are also fixed to the limiting member 13.

[0033] In actual application, two, four or more outlets 2 on the shell 1 can be evenly arranged around the corresponding guide covers 9. By arranging a conical guide cover 9 on the limiter 13, the liquid entering through the inlet of the shell 1 can flow to the outlets 2 around under the guidance of the guide cover 9. The guide cover 9 can play a good role in diverting and guiding the refrigerant, guiding the refrigerant to flow quickly to the outlets 2 on the shell 1, which is conducive to improving the distribution effect of this distributor.

[0034] Optionally, at least two connecting bars 12 are evenly arranged circumferentially along the limiting member 13, and there is a liquid passage gap between two adjacent connecting bars 12. Exemplarily, two, four or more connecting bars 12 can be provided. By providing a plurality of connecting bars 12, it is beneficial to improve the structural strength of the connection between the limiting member 13 and the limiting ring 5, so as to ensure that the limiting member 13 can continuously and stably limit the filter basket 3.

[0035] In the actual application process, each connecting bar 12 is inclined on the limiting member 13 to form a flow guiding vane structure. By inclining the connecting bar 12 on the limiting member 13, when the refrigerant entering through the inlet of the housing 1 flows through the limiting ring 5, it will flow and disperse along the inclined connecting bar 12, so as to form a spiral liquid flow in the filter basket 3. Then, under the guidance of the flow guiding cover 9, it can pass through the filter basket 3 more quickly and be evenly distributed to each outlet 2.

[0036] In addition, the spiral liquid flow can also make the impurities in the liquid move away from the filter basket 3 under the action of centrifugal force, and finally move downward along the surface of the flow guiding cover 9 to the gap between the flow guiding cover 9 and the limiting plate 11 for collection, and the impurities are less likely to accumulate on the inner wall of the filter basket 3.

[0037] Optionally, one end of the limiting ring 5 facing the filter basket 3 is provided with a protrusion 8 that can cooperate with the inner side of the filter basket 3. Exemplarily, the protrusion 8 is an annular structure, and the protrusion 8 is coaxially arranged with the filter basket 3. By providing the protrusion 8 on the limiting ring 5 that cooperates with the inner side of the filter basket 3, the protrusion 8 can play a good limiting role at the open end of the filter basket 3. Cooperating with the limiting plate 11 provided on the limiting member 13, the two ends of the filter basket 3 can be limited, which is beneficial to further improve the stability of the filter basket 3 in the housing 1 and ensure the filtering effect of the filter assembly.

[0038] Optionally, there is an accommodation gap for accommodating impurities between the flow guiding cover 9 and the limiting plate 11, and the accommodation gap communicates with the passage gap. One side of the flow guiding cover 9 facing the limiting plate 11 is provided with an accommodation groove 10 communicating with the accommodation gap. By providing the accommodation groove 10 communicating with the accommodation gap on one side of the flow guiding cover 9 facing the limiting plate 11, the impurities moving downward along the surface of the flow guiding cover 9 to the gap between the flow guiding cover 9 and the limiting plate 11 can be collected in the accommodation gap and the accommodation groove 10. Since the flow guiding cover 9 can play a good shielding role, the impurities are less likely to be driven and diffused by the liquid flow, thereby reducing the possibility of the impurities blocking the filter basket 3.

[0039] Optionally, a position on the housing 1 corresponding to one end of the outlet 2 is provided with a limit groove 6 that cooperates with the filter basket 3. By providing the limit groove 6, the end of the filter basket 3 can be further limited to prevent the filter basket 3 from deforming or moving during use. In actual use, the limit plate 11 can also drive the filter basket 3 to cooperate with the limit groove 6, and the limit plate 11 cooperates with the inner wall of the limit groove 6 to achieve clamping and limiting of the filter basket 3.

[0040] The air conditioner distributor described in the utility model has the advantages of simple structure, easy assembly and use, good diversion effect, and not easy to be blocked. By arranging a limit plate on the limit member and using the limit plate to support the inner side of the filter basket, the filter basket can be effectively limited, which is beneficial to avoid deformation of the filter basket during installation or use, and ensures that the filter assembly can continuously and stably filter the liquid entering the distributor. In addition, by arranging a conical guide cover on the limit member, the liquid entering through the shell inlet can flow to the surrounding outlets under the guidance of the guide cover, and the guide cover can play a good diversion and guiding role for the refrigerant, guiding the refrigerant to flow quickly to the outlet on the shell, which is beneficial to improve the distribution effect of this distributor.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
