The wall-mounted air conditioning indoor unit 100 according to the embodiment of the present invention generally includes a casing 10, a volute tongue 20, a structural member 22, and a baffle member 30. A first air supply outlet 11 is opened at the front side of the casing 10. The first air blowing port 11 is used for blowing an air flow in the casing 10 into a room to condition indoor air. The air flow may be cold air produced by the wall-mounted air conditioner indoor unit 100 in a cooling mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode. The number of the first blowing ports 11 may be one or more. Correspondingly, the number of the flow guide members 30 may be one or more. As shown in fig. 2, a plurality of first blowing ports 11 are provided at the front side of the casing 10 at intervals in the longitudinal direction of the casing 10. The first air supply outlet 11 can be oval, rugby-ball, rectangular, square, etc., and a horizontal grid, a vertical grid, a micropore form, etc. can be matched with the first air supply outlet 11. The housing 10 may be provided with an intake vent to allow indoor air to enter the housing 10 through the intake vent. As shown in fig. 4, the housing 10 may be formed by combining a front frame 101, a rear frame 102, and side covers 90 (only one is shown in fig. 4), and a front fascia 103 may be further provided on the front side of the housing 10. The volute tongue 20 is disposed in the casing 10, and a front end of the volute tongue 20 extends to an upper portion adjacent to the first blowing port 11. The structural member 22 is disposed in the casing 10, a front end of the structural member 22 is close to a lower portion of the first air supply outlet 11, so that the structural member 22 and the volute tongue 20 jointly define an air outlet duct (not numbered in the figure), and an inner wall of the air outlet duct close to the first air supply outlet 11 is tapered, where an overcurrent cross section of the inner wall gradually decreases along an airflow direction. The flow guiding element 30 is disposed in the air outlet duct and defines an air outlet gap 23 with the tapered portion thereof, and the flow guiding element 30 is configured to guide the airflow to the air outlet gap 23, so that the airflow is gradually and convergently blown out of the first air supply opening 11 toward the airflow center direction under the guidance of the inner wall of the air outlet duct.
In the wall-mounted air conditioner indoor unit 100 according to the embodiment of the present invention, the volute tongue 20 and the structural member 22 are arranged, and the front end of the volute tongue 20 and the front end of the structural member 22 are respectively extended to be close to the first air supply outlet 11, so that an air outlet duct is defined between the structural member 22 and the volute tongue 20, and the inner wall of the air outlet duct close to the first air supply outlet 11 is tapered, so that the flow cross section gradually decreases along the airflow direction. And, an air outlet gap 23 is defined by the guiding element 30 inside the air outlet duct and the tapered portion of the inner wall of the air outlet duct. In this way, the air flow (heat exchange air flow, fresh air flow, etc.) entering the air outlet duct flows forward, and is guided by the flow guiding member 30 to blow toward the inner wall of the air outlet duct, and finally flows into the air outlet gap 23. Because the air outlet section of the air outlet gap 23 is smaller, the air outlet speed is higher. The high-speed air flow is gradually converged towards the center of the air flow in the outward flowing process under the guidance of the tapered inner wall of the air outlet duct to form a convergence effect, so that the wind power is stronger, the air supply distance is longer, the air supply distance of the wall-mounted air conditioner indoor unit 100 is longer, and the air supply capacity is stronger.
In the wall-mounted air conditioner indoor unit 100 according to the embodiment of the present invention, the flow guiding member 30 not only defines the air outlet gap 23 with the inner wall of the air outlet duct, so as to achieve the effect of increasing the air speed, but also can guide the air flow to the air outlet gap 23, or force the air flow to flow toward the air outlet gap 23, so as to force the air flow to be guided by the converging inner wall, thereby forming the final converging air outlet effect. The existing hanging machine is also provided with a volute tongue, namely the invention can realize a very good polymerization air supply effect only by additionally arranging the structural member 22 and the flow guide member 30, has very simple structure and lower cost, is easy to realize mass production and popularization and has very ingenious conception.
In some embodiments, the outer surface of the baffle 30 includes an outer end surface 31 and a wind-guiding surface 32. The outer end surface 31 faces the first air blowing port 11, and the air guide surface 32 extends obliquely from the edge of the outer end surface 31 in a direction away from the first air blowing port 11 and toward the central axis of the first air blowing port 11. The wall-mounted air conditioner indoor unit 100 of the embodiment of the invention specially designs the appearance of the flow guide member 30, so that the flow guide member 30 comprises the outer end surface 31 and the air guide surface 32, and the obliquely extending air guide surface 32 is used for guiding the air flow, so that the air flow flows to the inner wall of the air outlet duct more stably and smoothly, and the resistance loss is reduced.
In some embodiments, the volute tongue 20 and the structure 22 are configured to make the upward angle of the airflow at the bottom section of the air outlet gap 23 greater than the downward angle of the airflow at the top section thereof, so that the airflow at the bottom section of the air outlet gap 23 drives the airflow at the rest sections to flow upward and forward together. The wall-mounted air conditioner indoor unit 100 of the embodiment of the invention limits the structures of the volute tongue 20 and the structural member 22, so that the shape of the air outlet duct meets the condition that the uplift angle of the airflow at the bottom section of the air outlet gap 23 is larger than the declination angle of the airflow at the top section. Because the rising angle of the air flow rising part is larger than the declining angle of the sinking part, the air flow mixed by the plurality of air flows integrally rises and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance. As shown in fig. 4 and 5, the volute tongue 20 is disposed along the length direction of the housing 10, and the front end is substantially horizontal; the structural member 22 is provided along the length of the housing 10, and has an arc-shaped surface gradually curved upward from rear to front. That is, the airflow at the top section of the air outlet gap 23 hardly declines, and the airflow at the bottom section of the air outlet gap 23 rises along the arc-shaped surface, so that the upward air outlet is realized.
Referring to fig. 4 and 5, the wall-mounted type air conditioning indoor unit 100 further includes a scroll casing 21 and a heat exchanger 50. The volute 21 is formed in the housing 10 behind the volute tongue 20, and defines a main air duct (not numbered) with the volute tongue 20. The volute 21 may be integrated on the rear frame 102. The heat exchanger 50 is disposed in the casing 10, the main air duct is configured such that an inlet faces the heat exchanger 50, and an outlet is communicated with the air outlet duct, so that the air flow heat-exchanged by the heat exchanger 50 reaches the first air supply outlet 11 through the main air duct and the air outlet duct. The structure of the volute tongue 20 and the volute 21 of the wall-mounted air-conditioning indoor unit 100 of the embodiment of the invention can be similar to the structure of the volute tongue and the volute of the existing on-hook machine. The volute casing 21 and the volute tongue 20 form a main air duct, so that the air flow subjected to heat exchange by the heat exchanger 50 is guided to the air outlet duct through the main air duct.
With continued reference to fig. 5, a second air supply outlet 12 is opened at the lower front side of the casing 10; the main duct is also configured to have an outlet communicating with the second supply outlet 12 so that the air exchanged heat by the heat exchanger 50 reaches the second supply outlet 12 through the main duct. The wall-mounted air-conditioning indoor unit 100 of the embodiment of the invention further comprises a second air supply outlet 12 arranged at the upper part of the front side of the shell 10, and the main air duct is communicated with the air outlet duct and the second air supply outlet 12, so that the wall-mounted air-conditioning indoor unit 100 has multiple air outlet forms, meets various different requirements of users, and can supply air only through the first air supply outlet 11, or only through the second air supply outlet 12, or simultaneously supply air through the first air supply outlet 11 and the second air supply outlet 12.
In some embodiments, the wall-mounted air conditioning indoor unit 100 further includes: and the air deflector 40 is rotatably arranged at the second air supply outlet 12 and is used for adjusting the proportion of the air flow of the main air duct flowing to the first air supply outlet 11 and the second air supply outlet 12 and adjusting the front and back air outlet direction of the second air supply outlet 12. As shown in fig. 5 to 7, the air flow direction of the air deflector 40 is shown by arrows at different angles. In fig. 5, the air deflector 40 is horizontally disposed, the second air supply outlet 12 is closed, and the air flow heat-exchanged by the heat exchanger 50 flows through the main air duct and the air outlet duct and then flows to the first air supply outlet 11. In fig. 6, the air deflector 40 rotates by a first angle, a small gap is formed between the upper end of the air deflector 40 and the volute tongue 20, a large part of the air flow which is subjected to heat exchange by the heat exchanger 50 flows to the second air supply outlet 12 through the main air duct, and a small part of the air flow flows to the first air supply outlet 11 through the main air duct and the air outlet duct. In fig. 7, the air guide plate 40 rotates by the second angle, and the upper end of the air guide plate 40 has a larger gap from the volute tongue 20, so that the amount of air flowing into the first air blowing port 11 is increased as compared with the state of fig. 6. Generally, in view of the comfort of the upward air outlet during refrigeration, the air outlet form shown in fig. 5 is preferably adopted during refrigeration; the downward blowing is more comfortable during heating, and the air-out form shown in fig. 6 is preferably adopted during heating; the air-out form shown in fig. 7 can be adopted when the air supply is carried out at a longer distance, the air is exhausted at a stronger strength and the air supply angle is wider, so that different air-out forms correspond to different requirements, and the user experience comfort is better.
As shown in fig. 4, the wall-mounted air conditioning indoor unit 100 according to the embodiment of the present invention may further include a plurality of swing blades 41 rotatably disposed at the second air blowing opening 12 for adjusting the left and right wind direction of the second air blowing opening 12. The specific structure of the swing blade 41 may adopt a structure that can realize left and right air outlet wind direction adjustment in the prior art, and details are not described here.
Referring to fig. 1 to 5, a first air inlet 13 is opened at the top of the housing 10, and a second air inlet 14 is opened at the front side. The wall-mounted air conditioning indoor unit 100 may further include a sliding plate 70 movably disposed at a front side of the casing 10 to open and close the first air supply outlet 11 and the second air intake inlet 14. In some embodiments, the first air supply outlet 11 is located below the second air inlet 14; the slide plate 70 is configured to move forward and upward to expose the first air supply outlet 11 and form an air inlet gap 72 with the housing 10 to allow air to enter through the second air inlet 14. The heat exchanger 50 generally includes a first heat exchange section 51, a second heat exchange section 52 and a third heat exchange section 53 which are connected in a bent manner. Through setting up slide 70, when realizing the outward appearance differentiation, also can increase effective air inlet area. According to simulation and actual measurement, the first heat exchange section 51 belongs to a high-speed area, and due to the influence of a front panel of a traditional hanging machine, the air inlet space of the traditional hanging machine is limited, available air inlet is less, and air inlet efficiency is lower. In the wall-mounted air conditioner indoor unit 100 according to the embodiment of the present invention, the sliding plate 70 is disposed at the front side of the front frame 101, and the sliding plate 70 moves forward and upward, so that the air intake gap 72 is defined between the sliding plate 70 and the front frame 101, and the second air intake 14 at the front side of the front frame 101 can also intake air, so as to meet the requirement of large air intake, and meanwhile, the air flow entering the casing 10 through the second air intake 14 can more effectively utilize the first heat exchange section 51, thereby improving the heat exchange efficiency of the heat exchanger 50. The sliding plate 70 may be moved by a driving mechanism (not shown), and a limiting rod 71 may be disposed on the side cover plate 90 along the up-down direction to limit the moving direction of the sliding plate 70 and support the sliding plate 70.
As shown in fig. 4 and 5, the wall-mounted air conditioning indoor unit 100 further includes a cross-flow fan 60 installed in the casing 10 and located in front of the heat exchanger 50, for promoting indoor air to enter the casing 10 through the first air inlet 13 and the second air inlet 14, so that heat exchange is completed between the indoor air and the heat exchanger 50, and then blowing the air flow to the main air duct. The wall-mounted air conditioning indoor unit 100 may further include an electric heater 80.
