Detailed Description
The embodiment of the invention provides an indoor unit of a vertical air conditioner, which is an indoor part of a split air conditioner and is used for conditioning indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like.

Fig. 6 is a cross-sectional view of the duct 20 and the baffle 30 of the indoor stand air conditioner shown in fig. 5. Fig. 7 is an exploded view of the indoor unit of the floor type air conditioner shown in fig. 1.
As shown in fig. 1 to 4, the indoor unit of a floor air conditioner according to an embodiment of the present invention may generally include a case 10, a duct 20, and a baffle 30. The casing 10 has a blower port 11. The air blowing port 11 is used to blow an air flow inside the casing 10 toward the room to condition the indoor air. The air flow can be cold air produced by the indoor unit of the vertical air conditioner in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like. The number of the air blowing ports 11 may be one or more. The housing 10 may further have an air inlet 12 for introducing indoor air. The housing 10 may be defined by a front cabinet 101 and a rear cabinet 102.
The air duct 20 is disposed in the casing 10, and has an air inlet 22 and an air outlet 21 facing the air supply opening 11, and is used for guiding the air flow in the casing 10 to the air supply opening 11, and an inner wall of the air duct 20 adjacent to the air outlet 21 is tapered such that an overflowing cross section thereof gradually decreases along an air flow direction. In other words, the flow cross section of the air duct 20 becomes gradually smaller in the air flow direction adjacent to the air outlet 21.
The guiding element 30 is disposed in the air duct 20 and defines an annular air outlet gap 15 with the tapered portion 150 thereof, for guiding the air flow to the annular air outlet gap 15, so that the air flow is gradually converged toward the air flow center direction under the guidance of the inner wall of the air duct 20 and sequentially flows out of the air outlet 21 and the air supply opening 11 (the air flow direction is indicated by arrows in fig. 2 and 3). Referring to fig. 4, the diversion member 30 is formed by a diversion line rotating a circle around the horizontal central axis, the diversion line comprises a first arc section (ab section) which is convex and is smoothly connected in sequence, a second arc section (bc section) which is concave, a third arc section (cd section) which is convex, a fourth arc section (de section) which is convex and a fifth arc section (ef section) which is convex, the first arc section (ab section), the second arc section (bc section) and the third arc section (cd section) are gradually far away from the horizontal central axis from the back to the front, and the terminal point of the fifth arc section (ef section) and the starting point of the first arc section (ab section) are on the horizontal central axis. In the embodiment shown in fig. 1, the air supply opening 11 is circular, the air outlet 21 is circular, the longitudinal section of the inner wall of the air duct 20 adjacent to the air outlet 21 is also circular, and the annular air outlet gap 15 is also a circular air outlet gap 15.
In the vertical air conditioner indoor unit of the embodiment of the invention, the inner wall of the air duct 20 close to the air outlet 21 is tapered, so that the overflowing section is gradually reduced along the airflow direction. Furthermore, the air deflector 30 inside the air duct 20 and the tapered portion 150 of the inner wall of the air duct 20 define an annular air outlet gap 15. In this way, the air flow (heat exchange air flow, fresh air flow, etc.) entering the air duct 20 from the air inlet 12 flows to the air outlet 21, and is guided by the flow guiding member 30 to blow toward the inner wall of the air duct 20, and finally flows into the annular air outlet gap 15. Because the air outlet cross section of the annular air outlet gap 15 is smaller, the air outlet speed is higher. The high-speed airflow is gradually converged towards the center of the airflow in the outward flowing process under the guidance of the gradually-reduced inner wall of the air duct 20 to form a convergence effect, so that the wind power is stronger, the air supply distance is longer, and the requirements of the indoor unit of the vertical air conditioner on long-distance air supply and strong air supply are met.
In the indoor unit of the vertical air conditioner of the embodiment of the invention, the flow guide member 30 not only defines the annular air outlet gap 15 with the inner wall of the air duct 20, so as to achieve the effect of increasing the air speed, but also can guide the air flow to the annular air outlet gap 15, or force the air flow to flow towards the annular air outlet gap 15, so as to force the air flow to be subjected to the polymerization and guidance of the tapered inner wall, and form the final polymerization air outlet effect. The invention realizes a very good polymerization air supply effect only by improving the shape of the air duct 20 and additionally arranging 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.
With continued reference to fig. 2 and 4, in the embodiment of the present invention, when the airflow flows to the flow guiding element 30, the airflow first flows through the first arc-shaped section (ab-section), and the airflow is easily guided by the flow guiding element 30 because the first arc-shaped section (ab-section) is convex. Then flows through the second arc-shaped section (bc section), and the second arc-shaped section (bc section) is designed to be concave, so that the flow velocity of the air flow is accelerated to quickly impact the inner wall of the air duct 20 away from the central axis of the air outlet 21. The third arc-shaped section (cd section) is of a convex design and is closer to the trend of the gradually-reduced inner wall of the air duct 20, so that the resistance of the third arc-shaped section (cd section) to the airflow is smaller in the process that the airflow is guided by the gradually-reduced inner wall of the air duct 20 and turns to turn towards the central axis of the air outlet 21. The convex design of the fifth arc-shaped section (ef section) is used as the outer end surface of the flow guide member 30, and the convex design of the fifth arc-shaped section (ef section) can enable the flow guide member 30 to have a certain effect of converging the airflow forwards. The fourth arc-shaped section (de section) is used as a transition section of the third arc-shaped section (cd section) and the fifth arc-shaped section (ef section) and is in an outward convex shape, so that the airflow smoothly transits from the third arc-shaped section (cd section) to the fifth arc-shaped section (ef section). The embodiment of the invention makes the whole flow guide member 30 be a symmetrical cone-like shape by specially designing the shape of the flow guide member 30, and the flow guide member is formed by rotating a circle around a horizontal central axis by a flow guide line comprising a convex first arc-shaped section (ab section), a concave second arc-shaped section (bc section), a convex third arc-shaped section (cd section), a convex fourth arc-shaped section (de section) and a convex fifth arc-shaped section (ef section) which are smoothly connected in sequence, so that the flow resistance in the air flow flowing process is smaller, the energy loss and the noise are smaller, the convergence effect is more obvious, and the polymerization air supply effect of the air outlet 21 is improved.
Further, the embodiment of the invention optimizes the size relationship of the arc-shaped sections to enhance the above effects. In some embodiments, the radius of the first arc segment (ab segment) is smaller than the radius of the third arc segment (cd segment), and preferably, the ratio of the radii of the first arc segment (ab segment) and the third arc segment (cd segment) is between 0.4 and 0.6, for example, the ratio of the radii is 0.4, 0.5, 0.6. The radius of the second arc-shaped segment (bc segment) is larger than the radius of the third arc-shaped segment (cd segment), preferably the ratio of the radii of the second arc-shaped segment (bc segment) and the third arc-shaped segment (cd segment) can be between 2.2 and 2.7, for example the ratio of radii is 2.2, 2.5, 2.7. The radius of the fourth arc-shaped segment (de segment) is smaller than or equal to the radius of the first arc-shaped segment (ab segment), and the ratio of the radius of the fourth arc-shaped segment (de segment) to the radius of the third arc-shaped segment (cd segment) can be preferably between 0.2 and 0.4, for example, the ratio of the radii is 0.2, 0.3 and 0.4. The radius of the fifth arc-shaped segment (ef segment) is larger than that of the third arc-shaped segment (cd segment), and the ratio of the radius of the fifth arc-shaped segment (ef segment) to that of the third arc-shaped segment (cd segment) can be preferably between 1.8 and 3.0, for example, the ratio of the radius is 1.8, 2.5 and 3.0.
As shown in fig. 2, the width D1 of the widest part of the baffle 30 may be greater than or equal to the width D2 of the air outlet 21. The inventor proves that D is obtained by theoretical analysis and experiments1When the air flow is larger than or equal to D2, the obvious air flow converging effect can be ensured, and the appearance of the whole vertical air conditioner indoor unit is attractive.
With continued reference to fig. 2 and 4, in some embodiments, the streamline shape of the inner wall of the tapered portion 150 of the wind tunnel 20 is the same as the streamline shape of the flow guide line of the opposite portion of the flow guide 30. In fig. 2, taking the streamline of the bottom section of the tapered portion 150 as an example, the streamline mainly includes an mn section and an np section, wherein the mn section has the same line type as the front section of the fourth arc section (de section) of the flow guide 30, and the np section has the same line type as the rear section of the fifth arc section (ef section) of the flow guide 30. Referring to fig. 2, the air inlet 22 is located lower than the air outlet 21, so that the air flows from bottom to top to the air guiding element 30, so that the air flow in the bottom section of the annular air outlet gap 15 drives the air flows in the other sections to flow upward and forward together. By positioning the air inlet 22 lower than the air outlet 21, the bottom section of the annular outlet gap 15 is located upstream of the other sections, so that the air flows into the bottom section of the annular outlet gap 15 more smoothly. Based on the above two designs, the bottom section of the annular air-out gap 15 has larger air volume and stronger wind power than other sections. The bottom powerful airflow has advantages in the processes of impact and polymerization with the upper portion of the annular air outlet gap 15 and the airflows on the two transverse sides, and the airflow is more powerfully driven to integrally lift and flow upwards towards the front upper side together, so that a better lifting and air supply effect is achieved. The embodiment of the invention designs the shape of the air duct 20 specially, so that the streamline shape of the inner wall of the tapered part 150 of the air duct 20 is the same as the streamline shape of the guide line of the opposite part of the guide member 30, the air outlet resistance can be further reduced, the air outlet strength is improved, meanwhile, the position of the air inlet 22 is lower than that of the air outlet 21, and the airflow flows to the guide member 30 from bottom to top, so that the airflow in the bottom section of the annular air outlet gap 15 drives the airflow in the other sections to flow upwards and forwards together. 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 shower type refrigeration experience is realized, and the use comfort of a user is improved. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
In some embodiments, the air inlet 12 may be opened at left and right side walls and/or a rear wall of the lower portion of the housing 10. The indoor unit of an upright air conditioner may further include a heat exchanger 50 and a fan 60. The heat exchanger 50 is disposed in the housing 10. A fan 60 is also disposed in the casing 10 for forcing the indoor air into the casing 10 to exchange heat with the heat exchanger 50, and then to be blown out from the air blowing port 11 through the air duct 20. It will be appreciated that the heat exchanger 50 and the fan 60 may be selected and arranged as desired and are described herein for exemplary purposes only. As shown in fig. 7, the wind tunnel 20 may include a front case 201, a rear case 202, and a water tray 203. The rear side and the lower side of the front case 201 are opened, and the air outlet 21 is opened on the front case 201. The front side and the lower side of the rear shell 202 are opened, and the rear shell 202 covers and buckles the rear side of the front shell 201 to form a structure with the lower side opened together. The drain pan 203 is covered and fastened to the lower sides of the front and rear cases 201 and 202 to close the open lower sides thereof. The air inlet 22 of the air duct 20 opens onto the drip tray 203. The air duct 20 is divided into a front shell 201, a rear shell 202 and a water pan 203, so that the parts can be independently processed and manufactured conveniently, and performance requirements can be better met. As shown in fig. 7, the heat exchanger 50 may be disposed inside the air duct 20 and mounted on the water tray 203. The heat exchanger 50 may have a two-stage structure, in which two heat exchange sections are flat and connected at top ends thereof, and bottom ends of the two heat exchange sections are disposed on the water pan 203 and located at two sides of the air inlet 22 respectively. The inverted "v" shape of the heat exchanger 50 provides a sufficient heat exchange area and provides more contact and heat exchange efficiency with the upward flow of the air entering the inlet 22. The water pan 203 is used for carrying the heat exchanger 50 on one hand and is used for receiving condensed water dropping from the surface of the heat exchanger 50 during air conditioning refrigeration on the other hand. The air duct 20 may be located at the middle upper portion of the housing 10, and one or more air inlets 12 may be opened at the lower portion of the housing 10, for example, as shown in fig. 7, the air inlets 12 are opened at the rear side of the housing 10. The blower 60 may be installed below the air duct 20 to face the air inlet 22 so as to blow the air flow entering the lower space of the housing 10 from the air inlet 12 toward the inside of the air duct 20. The fan 60 may be a double suction centrifugal fan as shown in fig. 7, or may be another type of fan. It will be appreciated that when the fan 60 is a double suction centrifugal fan, a volute 61 and a motor 62 are provided in association.
In some embodiments, the upright air conditioning indoor unit further includes a driving mechanism (not shown). The driving mechanism is installed in the air duct 20 and used for supporting the flow guide piece 30 and driving the flow guide piece 30 to move back and forth so as to open and close the air outlet 21 or adjust the air outlet area of the annular air outlet gap 15, so that the air outlet volume, the air speed and the air supply distance of the annular air outlet gap 15 can be adjusted, and the air supply adjusting mode is enriched. The driving mechanism can be an electric telescopic rod. For example, the distance d1 between the widest point of the baffle 30 and the inner wall of the non-tapered portion of the wind tunnel 20, and the distance d2 between the section of the baffle 30 that is linear with the tapered portion 150 of the wind tunnel 20 and the inner wall of the tapered portion 150 of the wind tunnel 20 are labeled in fig. 2, wherein the ratio of the sizes of d2 and d1 may be 0.125-2; when the guide member 30 is moved to enable d1 to be larger than d2, the air outlet bundle is more obvious, and the air supply distance is longer; when the diversion member 30 is moved to make d1< d2, the air outlet is diffused and the air supply quantity is large.
Referring now to fig. 5 and 6, in some embodiments, the indoor unit of a floor air conditioner further includes: and the guide vanes 40 are arranged in the air duct 20 and are used for combing the airflow flowing into the annular air outlet gap 15. When 21 air-outs in the gas outlet, the air-out of both sides does not receive effective guide, may lead to the rising momentum head too big, and whole air-out is comparatively in disorder, through setting up behind the stator 40, the air current can be combed once more, makes the air-out concentration higher, and the wind direction rises more rationally. In order to further enhance the combing effect, the guide vanes 40 are uniformly spaced along a direction perpendicular to the plane of the air outlet 21 and radially arranged on the inner side surface of the tapered portion 150 of the air duct 20, so as to comb the airflow flowing into the annular air outlet gap 15 in the radial direction of the air outlet 21.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention.
