Detailed Description

The utility model discloses at first provide a fluidic device that is used for wall-hanging air conditioning indoor set. A wall-mounted indoor air conditioner is an indoor air conditioner that is generally hung on a wall or other support location. Fig. 1 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, and the wall-mounted air conditioner indoor unit 1 according to the present invention includes a casing 10 on which a heat exchange airflow outlet 11 (the heat exchange airflow outlet is not shown in fig. 1, and the heat exchange airflow outlet in fig. 1 is covered by an air deflector) is provided along a lateral direction.

Fig. 2 is a schematic block diagram of a fluidic device according to one embodiment of the present invention. Referring to fig. 2, the jet device 100 of the present invention is applied to the wall-mounted air conditioner indoor unit 1, and includes a jet air duct 40 and a jet fan 50. The jet air duct 40 is provided with a jet air outlet 41 extending along the transverse direction. The jet fan 50 is communicated with the jet air duct 40 to controllably drive the air flow outside the jet device 100 to enter the jet air duct 40 and to be discharged from the jet air outlet 41, so that the natural air which flows out through the jet air outlet 41 and is not subjected to heat exchange is mixed with the heat exchange air flow discharged through the heat exchange air flow outlet 11.

Fig. 3 is a schematic cross-sectional view of a longitudinal section of the jet air duct extending in the front-rear direction according to an embodiment of the present invention, and referring to fig. 3, an air outlet chamber 43 communicating with the jet air outlet 41 is defined inside the jet air duct 40, and the air outlet chamber 43 is tapered in the airflow flowing direction therein.

The utility model discloses a fluidic device 100 is compared in utilizing the passive drainage's of negative pressure mode among the prior art in penetrating into efflux wind channel 40 with the outside air initiatively through efflux fan 50, and this application is through setting up efflux fan 50 initiative efflux, and the efflux amount of wind improves greatly, and the air supply distance increases. And, the air outlet chamber 43 that prescribes a limit in the efflux wind channel 40 reduces in the air current flow direction in it, and the accessible air outlet chamber is to the air current of flow direction efflux air outlet with higher speed, has further improved the air current flow speed, and the natural air who avoids efflux fan 50 to jet into diminishes and leads to the problem that the air supply distance is shorter when reaching efflux air outlet 41. When the jet device 100 is integrated in the wall-mounted air conditioner indoor unit 1, the natural air flowing out of the jet air duct 40 without heat exchange can be mixed with the heat exchange air flowing out of the heat exchange air flow outlet 11 to form softer mixed air, so that the air outlet of the wall-mounted air conditioner indoor unit 1 is prevented from being too cold or too hot, the whole air supply amount is increased, the air supply range is expanded, and the use experience of a user is improved.

Meanwhile, the jet air outlet 41 and the heat exchange airflow outlet 11 both extend along the transverse direction, that is, the shapes of the two air outlets are matched, so that the mixing effect between the two airflows sent out from the two air outlets is better.

In some embodiments, the jet outlet 41 is a strip outlet extending in the transverse direction. The jet fan 50 is located at one of the lateral outer sides of the jet air duct 40 and communicates with the lateral end of the jet air duct 40 adjacent to the jet fan 50 to convey natural air laterally into the jet air duct 40. Thereby, the thickness of the jet device 100 in the front-rear direction is reduced, and the width thereof in the lateral direction is made slightly wider, thereby making it more suitable for the wall-mounted air conditioning indoor unit 1. When the jet device 100 is integrated in the wall-mounted air conditioning indoor unit 1, the thickness of the wall-mounted air conditioning indoor unit 1 in the front-rear direction is not increased, the width of the wall-mounted air conditioning indoor unit 1 in the transverse direction is slightly longer than that of a conventional hanging machine, and the wall-mounted air conditioning indoor unit 1 is not different from the conventional hanging machine in other aspects and is still very light.

In some embodiments, the jet outlet 41 is opened at the front side of the jet duct 40 to facilitate the forward air supply, so that the jet device 100 is suitable for most wall-mounted air conditioning indoor units supplying air forward.

Further, the outlet chamber 43 tapers from the rear to the front. That is, the flow direction of the air flow in the outlet chamber 43 is generally in the front-rear direction from the rear. When the airflow passes through the air outlet cavity 43, the flow area is gradually reduced, and the flow speed is gradually increased, so that the flow speed of the airflow sent by the jet device 100 is increased.

Because the jet air outlet 41 is located at the front side of the jet air duct 40 and extends along the transverse direction, and the jet fan 50 is communicated with one of the transverse end portions of the jet air duct 40, the flow direction of the air flowing into the jet air duct 40 is perpendicular to the flow direction of the air flowing out of the jet air duct 40. That is, the air flow needs to be reversed within the jet duct 40 by approximately 90 degrees.

For this purpose, in some embodiments, the jet air duct 40 further defines a gas collecting chamber 44 communicated with the jet fan 50, and the gas collecting chamber 44 is located at the rear side of the air outlet chamber 43, so that the natural air flowing into the jet air duct 40 flows through the gas collecting chamber 44 and the air outlet chamber 43 in sequence and then is discharged from the jet air outlet 41. It should be noted that the natural air in the present invention means air that has not undergone heat exchange.

This application air-out chamber 43 rear side in efflux wind channel 40 is equipped with gas collecting chamber 44 specially, the natural air of efflux fan 50 driven flows into gas collecting chamber 44 earlier, then flow to air-out chamber 43, accessible gas collecting chamber 44 increases the static pressure, thereby will follow the air current flow direction correction that transversely flows in gas collecting chamber 44 when guaranteeing great induced air volume and flow out gas collecting chamber 44 and air-out chamber 43 along the fore-and-aft direction, thereby be convenient for the air current to send out through the efflux air outlet 41 that is in the front side, the air current flow resistance has been reduced, also be convenient for efflux air outlet 41 department forms comparatively even air-out.

In some embodiments, the jet air duct 40 is a horizontally disposed flat air duct, and the air collecting chamber 44 defined inside the jet air duct 40 is a horizontally disposed flat cavity, on one hand, the air collecting chamber 44 can provide a flow space with a larger cross section for natural air flowing into the jet air duct 40 from one of the lateral ends of the jet air duct 40, so that the natural air flows to the other lateral end of the jet air duct 40 under the condition of smaller flow resistance, thereby facilitating the formation of more uniform outlet air in the lateral direction of the jet air outlet 41; on the other hand, the flow area of the front opening of the air collecting chamber 44 is relatively small, so that the natural air flowing from the air collecting chamber 44 to the air outlet chamber 43 has a relatively high flow speed.

In some embodiments, the duct wall 40a of the jet duct 40 defining the top of the duct chamber 43 extends straight from the rear to the front, and the duct wall 40b of the jet duct 40 defining the bottom of the duct chamber 43 extends obliquely upward from the rear to the front. Thereby, the defined outlet chamber 43 is tapered from the rear to the front. The air duct wall 40a for defining the top of the air cavity 43 extends straightly from back to front, which facilitates the abutting of the jet air duct 40 with the casing 10 of the wall-mounted air conditioning indoor unit 1, thereby enabling the jet air outlet 41 of the jet air duct 40 to be disposed adjacent to the heat exchange air flow outlet 11 after the jet device 100 is integrated in the wall-mounted air conditioning indoor unit 1, and enabling the structure of the wall-mounted air conditioning indoor unit 1 to be more compact.

In some alternative embodiments, the outlet chamber 43 may also have another taper shape that tapers from back to front. For example, the air duct wall 40a for defining the top of the air chamber 43 is obliquely extended downward from the rear to the front, and the air duct wall 40b for defining the bottom of the air chamber 43 is straightly extended from the rear to the front. For another example, the duct wall 40a defining the top of the wind chamber 43 extends obliquely downward from the rear to the front, and the duct wall 40b defining the bottom of the wind chamber 43 extends obliquely upward from the rear to the front.

In some embodiments, the jet fan 50 may include a centrifugal fan 51 and a centrifugal volute 52 located outside the centrifugal fan 51, and the centrifugal volute 52 and the jet duct 40 are in sealed communication through a wind guide passage 60. Because the centrifugal volute 52 is oriented downward, the transverse end of the jet air duct 40, which is in communication with the jet fan 50, is oriented horizontally, and the two are oriented vertically, which is not favorable for airflow if directly communicated. The air guide channel 60 is arranged between the two to be used as a section for buffering and reversing the air flow, so that the flow resistance of the air flow can be reduced.

Further, the air guide passage 60 extends from top to bottom, first, to be bent toward the lateral outer side of the casing 10, and then, to be bent toward the lateral inner side of the casing 10, so as to smoothly communicate with the centrifugal scroll 52 and the jet air duct 40 at the same time. Therefore, the airflow is reversed under the premise of small flow resistance by slightly prolonging the airflow flow path between the centrifugal volute 52 and the jet flow air duct 40, and the high flow speed of the airflow is ensured. The extension of the airflow path between the centrifugal volute 52 and the jet duct 40 is very small and has little effect on the airflow velocity.

In order to further improve the air outlet uniformity of the jet air outlet 41 in the transverse direction, in some embodiments, a plurality of flow guiding ribs 42 arranged at intervals in the transverse direction may be disposed on the inner side of the jet air outlet 41 to guide the natural air flowing in the transverse direction in the jet air duct 40 to the jet air outlet 41. That is to say, the natural air flowing transversely in the jet air duct 40 can be guided to the jet air outlet 41 relatively uniformly by the guide rib 42, so that the heat exchange airflow flowing out from any position of the heat exchange airflow outlet 41 can be mixed with the natural air flowing out from the jet air outlet 41, and the outlet uniformity of the wall-mounted air conditioner indoor unit 1 in the transverse direction is improved in two aspects of outlet air temperature and outlet air quantity.

Further, the flow guiding rib 42 may be disposed in the air outlet cavity 43. That is, the length of the flow guiding rib 42 extending in the front-back direction is less than or equal to the length of the air outlet cavity 43 extending in the front-back direction, so as to avoid the problem that the amount of natural air flowing to the other lateral end of the jet air duct 40 is too small due to the fact that the length of the flow guiding rib 42 extending to the air collecting cavity 44 generates a large resistance to the natural air flowing laterally.

Fig. 4 is a schematic cross-sectional view of a jet stack taken along a horizontal cross-sectional plane according to some embodiments of the present invention, with the dashed arrows in fig. 4 indicating the direction of airflow into the jet stack. In some embodiments, referring to fig. 4, the air guiding rib 42 may have a shape that is convexly curved toward a side facing away from the windward side thereof, so that the air guiding rib 42 may have a capability of retaining a preset amount of air flow on the windward side (the side where the windward side is located) thereof, and the preset amount of air flow flows forward to the jet outlet 41 under the guiding action of the air guiding rib 42, thereby achieving uniform air outlet of the jet outlet 41 in the transverse direction by cooperation of the plurality of air guiding ribs 42.

Fig. 5 is a schematic enlarged view of a portion a in fig. 4. In some embodiments, the air guiding rib 42 may include a first straight section 421 extending along the preset direction, an arc section 422 extending from the end of the first straight section 421 to protrude from the rear to the front in the preset direction, and a second straight section 423 extending from the end of the arc section 422 to the front of the jet outlet 41. That is, the first flat section 421 and the second flat section 423 are perpendicular to each other, and the central angle of the arc-shaped section 422 is 90 °. The extending direction of the first straight section 421 is the same as the direction of the airflow flowing into the jet air duct 40, which not only can keep a preset amount of airflow below the first straight section 421 so as to guide the airflow to the jet air outlet 41 through the arc-shaped section 422 and the second straight section 423, but also can reduce the flow resistance of the airflow after encountering the arc-shaped section 422.

Further, the depths of the plurality of air guide ribs 42 arranged in order in the above-described preset direction in the front-rear direction increase in order. That is, the depths of the plurality of air guide ribs 42 in the front-rear direction are increased in a step-like manner in the preset direction. Therefore, the preset air flow remained on the windward side of each flow guiding rib 42 can be basically the same, and the air outlet uniformity of the jet device 100 in the transverse direction is further improved. Since the front end of the second straight section 423 of each flow guiding rib 42 extends to the jet outlet 41, the front ends of the flow guiding ribs 42 are flush, and the rear ends of the plurality of flow guiding ribs 42 sequentially arranged along the preset direction extend backward to a greater depth.

In some embodiments, the end portion of the jet outlet 41 adjacent to the jet fan 50 is provided with an end portion flow guiding rib 45, and the end portion flow guiding rib 45 is located on the upstream side of each flow guiding rib 42 in the preset direction. That is, after the airflow flows into the jet air duct 40, the airflow is guided by the end guide ribs 45 and then by the plurality of guide ribs 42.

Further, the end deflector rib 45 has a shape convexly curved toward the windward side thereof, that is, the end deflector rib 45 has an arc shape convexly curved and extended from the rear to the front in the direction opposite to the preset direction. Therefore, part of the air flow flowing to the end diversion rib 45 can be guided backwards, so that the air flow and other air flows jointly flow along the preset direction, and the phenomenon that the air flow flowing into the jet air duct 40 is seriously uneven due to the fact that the air flow of the jet air outlet 41 is seriously uneven because the air flow of the majority of the air flow is sent out through the end part, close to the jet fan 50, of the jet air outlet 41 is avoided. In addition, the protruding direction of the end diversion rib 45 can reduce the flow resistance of the end diversion rib 45 to the air flow, and avoid the adverse phenomena of vortex and the like caused by the formation of a concave cavity on the windward side of the end diversion rib 45.

Further, in order to ensure the air outlet uniformity of the jet outlet 41 in the transverse direction, the depth of the end diversion rib 45 in the front-rear direction is set to be smaller than the depth of any one of the diversion ribs 42 in the front-rear direction. If the depth of the end diversion rib 45 in the front-rear direction is too large, the airflow at the plurality of diversion ribs 42 adjacent to the end diversion rib 45 may be small, and the plurality of diversion ribs 42 cannot retain a sufficient amount of airflow on the windward side thereof, so that the uniformity of the air outlet of the jet air outlet 41 in the transverse direction cannot be ensured.

In other embodiments, the air guiding ribs 42 may be straight air guiding ribs extending in the front-back direction, and the design is simple and easy to arrange.

The utility model also provides a wall-hanging air conditioning indoor unit 1, it includes casing 10, offers on the casing 10 along transversely extending in order to be used for seeing off the heat transfer air current export 11. Fig. 6 is a schematic cross-sectional view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention, and fig. 7 is a schematic structural view of a wall-mounted air conditioner indoor unit according to an embodiment of the present invention with a casing thereof hidden. Referring to fig. 1, 6 and 7, the interior of the cabinet 10 may be provided with a heat exchanger 20 and a fan 30, and the heat exchanger 20 may exchange heat with an air flow passing therethrough to generate a heat exchange air flow. The fan 30 may cause the heat exchange air flow in the cabinet 10 to be sent out through the heat exchange air flow outlet 11. The top of the housing 10 defines a main air inlet 12, and the heat exchanger 20 may be disposed in an airflow path between the main air inlet 12 and the fan 30 to exchange heat with an airflow entering the housing 10 through the main air inlet 12. The casing 10 may include a cover 13 at a rear side and a front panel 14 at a front side, and two end panels 16 at lateral sides, the cover 13, the front panel 14 and the two end panels 16 being coupled in a mating manner.

In particular, the wall-mounted air conditioning indoor unit 1 further includes the fluidic device 100 described in any of the above embodiments. The jet device 100 is used for controllably causing the air flow outside the wall-mounted air conditioner to flow into the wall-mounted air conditioner and to be sent out through the jet air outlet 41, and mixing the air flow sent out through the jet air outlet 41 with the heat exchange air flow flowing out through the heat exchange air flow outlet 11, so that softer mixed air is formed, the air outlet of the wall-mounted air conditioner indoor unit 1 is prevented from being too cold or too hot, and the comfort experience of the wall-mounted air conditioner indoor unit is improved.

In some embodiments, the heat exchange airflow outlet 11 is a strip-shaped outlet that is opened at the bottom of the front side of the casing 10 and extends along the transverse direction of the casing 10, and the jet air outlet 41 of the jet device 100 is a strip-shaped air outlet that is opened at the front side of the jet air duct 40 of the jet device 100 and extends along the transverse direction, so as to enlarge the air supply range of the wall-mounted air conditioning indoor unit 1 in the transverse direction, and further, the heat exchange airflow outlet 11 and the jet air outlet 41 can be arranged adjacent to each other, so that the heat exchange airflow sent out from the heat exchange airflow outlet 11 and the natural air sent out from the jet air outlet 41 can be better mixed, and the air outlet. The heat exchange airflow outlet 11 and the jet outlet 41 extend substantially the same length in the transverse direction to further enhance the mixing effect between the two airflows delivered from the two outlets.

Further, the jet fan 50 of the jet device 100 is disposed at one of the lateral sides in the cabinet 10. Therefore, only a space for accommodating the jet fan 50 needs to be left in one of the lateral side portions in the housing 10, and the housing 10 does not occupy the space in the front-rear direction and does not need to be provided with a fan shielding device. On the one hand, the casing 10 of the whole wall-mounted air conditioner indoor unit 1 is ensured to be still complete, so that the whole wall-mounted air conditioner indoor unit 1 can keep a good attractive effect, on the other hand, the width of the wall-mounted air conditioner indoor unit 1 is only slightly longer than that of the traditional hanging machine in the transverse direction, the shape of the wall-mounted air conditioner indoor unit is consistent with that of the traditional hanging machine, and the wall-mounted air conditioner indoor unit is not different from that of the traditional hanging machine in other aspects.

In some embodiments, a lateral side plate of the casing 10 adjacent to the jet fan 50 is provided with a jet air inlet 15 communicated with an airflow inlet of the jet fan 50, so as to allow air outside the wall-mounted air conditioner indoor unit 1 to flow to the jet fan 50 through the jet air inlet 15. In particular, the jet intake 15 may be formed in the end plate 16 and in part of the housing 13. The airflow inlet of the jet fan 50 may be directed toward the jet intake opening 15, i.e., the airflow inlet of the jet fan 50 is directed toward the lateral outside of the cabinet 10. So set up, efflux air intake 15 and main air intake 12 are in two different sides of casing 10 respectively, and on the one hand, the air inlet of two air intakes is mutual noninterference, and on the other hand, the setting of efflux air intake 15 can not reduce the size of main air intake 12, has increased the total flow area of air intake of wall-hanging air conditioning indoor set 1, has improved its intake.

In some embodiments, the jet stack 40 is disposed adjacent to the cabinet 10 at the bottom of the cabinet 10. That is, the jet air duct 40 is disposed at the bottom of the casing 10 and abuts against the bottom surface of the casing 10, so that the heat exchange air flow outlet 11 at the bottom of the front side of the casing 10 is disposed adjacent to the jet air outlet 41 at the front side of the jet air duct 40.

Fig. 8 is a schematic structural view of a wall-mounted air conditioner indoor unit according to another embodiment of the present invention. In other embodiments, the jet air duct 40 is disposed below the casing 10 at a distance from the casing 10 to form a guide air duct 80 between the heat exchange air flow outlet 11 and the jet air outlet 41. That is to say, the both sides in drainage wind channel are heat transfer air outlet 11 and efflux air outlet 41 respectively, along with the air supply of heat transfer air outlet 11 and efflux air outlet 41, the both sides in drainage wind channel 80 all can produce the negative pressure, consequently, the air flow volume of introducing in drainage wind channel 80 under the negative pressure effect of both sides is bigger, the natural air that introduces through drainage wind channel 80 mixes with the natural air that sends out through efflux air outlet 41 and the heat transfer air that sends out through heat transfer air outlet 11, the whole induced air volume and the whole air supply volume of wall-hanging air conditioning indoor set have further been improved.

In some embodiments, the cabinet 10 further includes a frame 70 for supporting the heat exchanger 20 and the fan 30, and the jet fan 50 is disposed at one of lateral outer sides of the frame 70, so that the arrangement between the jet fan 50 and other structures inside the cabinet 10 is more compact, thereby reducing the volume of the wall-mounted air conditioning indoor unit 1. Specifically, the jet fan 50 may be fixedly supported on the frame 70, thereby avoiding additional arrangement of other fan support structures and simplifying the structure of the wall-mounted air conditioner indoor unit 1.

Further, in order to improve the structural stability of the jet air duct 40, the other transverse end of the jet air duct 40 may be fixedly connected to the frame 70, so as to avoid the inclination or shaking of the jet air duct 40 caused by the suspended arrangement of the other transverse end of the jet air duct 40.

In some embodiments, the fan 30 is a cross flow fan having a rotation axis extending in a lateral direction of the casing 10, and the air supply amount is large and the air supply range in the lateral direction is large.
