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. For example, the indoor unit of the floor air conditioner may be an indoor unit of an air conditioner that performs cooling/heating by a vapor compression refrigeration cycle.

Fig. 7 is an exploded view of the indoor unit of a floor type air conditioner shown in fig. 5.
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 first blowing port 11 at a front side thereof. The first blowing port 11 is used to blow an air flow in the casing 10 into 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 first blowing ports 11 may be one or more. The housing 10 may further have an air inlet 13 for introducing indoor air. The housing 10 may be formed by combining a front cabinet 101 and a rear cabinet 102. The air duct 20 is arranged in the casing 10, and has an air inlet 23 and a first air outlet 21 facing the first air supply outlet 11, and is used for guiding the air flow in the casing 10 to the first air supply outlet 11; wherein the inner wall 252 of the air duct 20 adjacent to the top edge and the lateral both side edges of the first air outlet 21 is a plane extending from the rear to the front, the inner wall 251 of the air duct 20 adjacent to the bottom edge of the first air outlet 21 includes a bottom arc-shaped surface 2511 inclined from the rear to the front gradually toward the horizontal central axis of the first air outlet 21 and a bottom plane 2512 extending from the bottom arc-shaped surface 2511 to the front, and the air inlet 23 is positioned lower than the first air outlet 21. In other words, adjacent to the first air outlet 21, along the airflow direction, the flow cross section of the air duct 20 gradually decreases and then maintains the minimum flow cross section until reaching the first air outlet 21. The flow guiding member 30 is configured to define an annular air outlet gap 25 with an inner wall of the air duct 20 adjacent to the first air outlet 21, and is used for guiding the air flow to the annular air outlet gap 25 and making the air flow out of the first air supply outlet 11 under the guidance of the flow guiding member 30 and the inner wall of the air duct 20 and gradually converge towards the air flow center (the air flow direction is indicated by arrows in fig. 2 and 3).
In the indoor unit of a floor air conditioner according to the embodiment of the present invention, the flow guiding element 30 is disposed to define the annular air outlet gap 25 with the inner wall of the air duct 20 adjacent to the first air outlet 21, so that the air flow (heat exchange air flow, fresh air flow, etc.) entering the air duct 20 from the air inlet 23 will be guided by the flow guiding element 30 to blow toward the inner wall of the air duct 20 and finally flow into the annular air outlet gap 25 in the process of flowing to the first air outlet 21. Because the air outlet cross section of the annular air outlet gap 25 is smaller, the air outlet speed is higher. The inner wall 252 of the air duct 20 close to the top edge and the two lateral side edges of the first air outlet 21 is a plane extending from back to front, and the inner wall 251 of the air duct 20 close to the bottom edge of the first air outlet 21 comprises a bottom arc surface 2511 inclined from back to front gradually towards the horizontal central axis of the first air outlet 21 and a bottom plane 2512 extending from the bottom arc surface 2511 to front, so that high-speed airflow is converged towards the center direction of the airflow gradually in the outward flowing process under the guide of the special-shaped inner wall of the air duct 20 and the flow guide piece 30, a convergence effect is formed, wind power is stronger, the air supply distance is farther, and the requirements of the indoor unit of the vertical air conditioner on long-distance air supply and strong air supply are met. Meanwhile, the air inlet 23 is lower than the first air outlet 21 in a matched manner, so that the air flow flows to the flow guide piece 30 from bottom to top, and the high-speed air flow still has a certain upward momentum after flowing to the first air outlet 21 from the lower part and guiding, so that the whole air outlet can be raised, and the effect of not directly blowing people is achieved.
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 25 with the inner wall of the air duct 20 to achieve the effect of increasing the air speed, but also can guide the air flow to the annular air outlet gap 25, or force the air flow to flow towards the annular air outlet gap 25, so that the air flow is forced to be converged and guided by the special-shaped inner wall of the air duct, and the final converged air outlet effect is formed. 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.
Referring to fig. 4, the outer surface of the diversion member 30 is formed by rotating the diversion line around a horizontal axis by one circle, the diversion line includes a first line segment (ab segment), an inward concave second arc segment (bc segment), an outward convex third arc segment (cd segment), an outward convex fourth arc segment (de segment), a fifth line segment (ef segment), an outward convex sixth arc segment (fg segment) and a seventh line segment (gh segment), which are connected in sequence, the first line segment (ab segment), the fifth line segment (ef segment) and the seventh line segment (gh segment) are straight line segments or outward convex arc segments, the second arc segment (bc segment), the third arc segment (cd segment) and the fourth arc segment (de segment) are gradually far away from the horizontal axis from the backward direction and the front direction, and the terminal point of the seventh line segment (gh segment) and the starting point of the first line segment (ab segment) are on the same horizontal axis. The embodiment of the invention also specially designs the shape of the flow guide piece 30, so that the flow guide piece 30 is formed by rotating a flow guide line which comprises a first line segment (ab segment), a concave second arc segment (bc segment), a convex third arc segment (cd segment), a convex fourth arc segment (de segment), a fifth line segment (ef segment), a convex sixth arc segment (fg segment) and a seventh line segment (gh segment) which are smoothly connected in sequence around a horizontal central axis for one circle, 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 aggregated air supply effect of an air outlet is improved. In addition, the flow guide member 30 of the embodiment of the present invention may have a solid structure or a hollow structure.
Further, the embodiment of the invention optimizes the shape and size relationship of each line segment to enhance the above effects. Referring to fig. 2 to 4, in the embodiment of the present invention, the first line segment (ab segment) is a convex arc segment, and the radius of the first line segment is 0.4-0.6 times, for example, 0.4 times, 0.5 times, 0.6 times, of the radius of the third arc segment (cd segment); the radius of the second arc-shaped segment (bc-segment) is 2.2-2.7 times, e.g. 2.2, 2.5, 2.7 times, the radius of the third arc-shaped segment (cd-segment); the radius of the fourth arc segment (de segment) is 0.4-0.8 times, e.g., 0.4 times, 0.6 times, 0.8 times the radius of the third arc segment (cd segment); the fifth line segment (ef segment) is a straight line segment; the radius of the sixth arc-shaped segment (fg segment) is 0.2-0.4 times, e.g. 0.2, 0.3, 0.4 times, the radius of the third arc-shaped segment (cd segment); the seventh segment (gh segment) is a convex arc segment with a radius 1.8-3.0 times, e.g. 1.8, 2.5, 3.0 times, the radius of the third arc segment (cd segment). From another perspective, the outer surface of the air guide member 30 includes a rear end surface 37, a first annular air guide surface 31, a second annular air guide surface 32, a third annular air guide surface 35, an annular outer peripheral surface 33, an annular transition surface 36 and a front end surface 34, wherein the rear end surface 37 is defined by a first segment (ab segment), the first annular air guide surface 31 is defined by a second arc segment (bc segment), the second annular air guide surface 32 is defined by a third arc segment (cd segment), the third annular air guide surface 35 is defined by a fourth arc segment (de segment), the annular outer peripheral surface 33 is defined by a fifth segment (ef segment), the annular transition surface 36 is defined by a sixth arc segment (fg segment), and the front end surface 34 is defined by a seventh segment (gh segment). Here, when the fifth line segment (ef segment) is a convex arcuate segment, the radius is at least 5 times, for example 5 times, the radius of the third arcuate segment (cd segment). When the airflow flows to the airflow guide 30, the airflow first flows through the first line segment (ab segment), and the airflow is easily guided by the airflow guide 30 because the first line segment (ab segment) is a convex arc segment. Then, the air 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 air flow speed is accelerated to quickly impact the inner wall of the air duct 20 away from the central axis of the first air outlet 21. The third arc-shaped section (cd section) and the fourth arc-shaped section (de section) are both convex in design to be closer to the inner wall of the air duct 20, so that the resistance of the airflow in the process of flowing into the annular air outlet gap 25 is smaller. The fifth line segment (ef segment) is a straight line segment, and can further comb the air outlet flow line for the air current entering the annular air outlet gap 25, guide the air outlet direction, reduce the air outlet resistance, promote the air outlet intensity, and reach the high-speed air supply effect of efflux. The seventh line segment (gh segment) is designed as a convex arc segment, and the front end surface 34 of the flow guide element 30 is designed as a convex shape, so that the flow guide element 30 has a certain effect of converging the airflow forwards. The sixth arc-shaped segment (fg segment) is a transition section of the fifth line segment (ef segment) and the seventh line segment (gh segment) and is convex so that the air flow smoothly transits from the fifth line segment (ef segment) to the seventh line segment (gh segment).
As shown in fig. 2, in some embodiments, the fifth line segment (ef segment) is a straight line segment; the air guide member 30 is configured to define an annular air outlet gap 25 between an annular surface defined by the front portion of the fourth arc-shaped section (de section), the fifth line section (ef section) and the rear portion of the sixth arc-shaped section (fg section) and the bottom arc-shaped surface 2511 and the bottom plane 2512, and at least a part of the front end surface 34 of the air guide member 30 extends beyond the first air supply outlet 11. By defining the annular air outlet gap 25 mainly by the linear structure of the fifth line segment (ef segment) and between the bottom arc surface 2511 and the bottom plane 2512, an obvious air flow guiding effect can be ensured; at least a part of the front end surface 34 of the flow guide member 30 exceeds the first air supply outlet 11, and the airflow flowing out of the first air supply outlet 11 can be continuously converged forwards, so that the jet flow air outlet effect is further improved.
Further, the embodiment of the present invention optimizes the size relationship between the air guide 30 and the air duct 20 to enhance the above effects. Referring to fig. 2, the arc radius R of the bottom arc-shaped surface 2511 is 0.9-1.1 times, for example, 0.9 times, 1.0 times, 1.1 times, of the vertical distance d1 between the fifth line segment (ef segment) and the bottom plane 2512, and the air outlet loss is too large due to too small round angle of the bottom arc-shaped surface 2511, and the air outlet is too biased due to too large round angle, which affects the overall air outlet distance. The horizontal distance L4 between the intersection point of the tangents at the two ends of the fourth arc-shaped segment (de segment) and the intersection point of the tangents at the two ends of the sixth arc-shaped segment (fg segment) is 1.5-2 times, for example, 1.5 times, 1.8 times, or 2.0 times, the vertical distance d1 between the fifth line segment (ef segment) and the bottom plane 2512, and the approximately straight segment with enough length can guide the outlet air to be more straight and further improve the outlet air distance. The width D1 of the widest part of the air guide 30 is 0.6-0.8 times, such as 0.6 times, 0.7 times, 0.8 times, of the vertical distance L3 between the plane of the air duct 20 near the top edge of the first air outlet 21 and the bottom plane 2512, and this dimension mainly affects the air volume, and the smaller the multiple, the larger the multiple, the smaller the multiple. With continued reference to fig. 2, the longest length L1 of the baffle 30 may also be defined, for example, the length L1 of the longest of the baffle 30 is 2.9-3.1 times, for example, 2.9 times, 3.0 times, 3.1 times, of the horizontal distance L4 between the intersection of the two end tangents of the fourth arc-shaped segment (de segment) and the intersection of the two end tangents of the sixth arc-shaped segment (fg segment), so that the baffle 30 and the approximately straight segment together guide the forward straight wind. In addition, the longest length L1 of the air guiding element 30 may be defined as 0.6-0.8 times, for example, 0.6 times, 0.7 times, or 0.8 times, of the length L2 from the rear wall to the front wall of the air duct 20 corresponding to the first air outlet 21, so as to balance the air passing through the air duct 20 and ensure uniform air outlet of the first air outlet 11.
Referring now to fig. 5 and 6, in some embodiments, the indoor unit of a floor air conditioner further includes: and the guide vanes 70 are arranged at intervals on the inner wall of the air duct 20 close to the first air outlet 21, and each guide vane 70 is arranged along the front-back direction so as to comb the airflow flowing into the annular air outlet gap 25 in the radial direction of the first air outlet 21. When first gas outlet 21 air-out, 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 70, the air current can be combed once more, makes the air-out concentration higher, and it is more reasonable that the wind direction rises.
In some embodiments, the air chute 20 is further configured to: a ring 24 is formed at the front end of the first air outlet 21, and the ring 24 is inclined from the first air outlet 21 to the first air blowing port 11 from the rear to the front away from the horizontal central axis of the first air outlet 21. The ring 24 can make the air duct 20 and the casing 10 more closely fit, so that the air flowing through the annular air outlet gap 25 can flow through the first air outlet 21 and the first air supply outlet 11 more smoothly.
The indoor unit of an upright air conditioner may further include a heat exchanger 40 and a fan 50. The heat exchanger 40 is disposed within the housing 10. The fan 50 is disposed in the casing 10, and is used for causing indoor air to enter the casing 10 to exchange heat with the heat exchanger 40, and then to be blown out from the first air supply outlet 11 through the air duct 20. As shown in fig. 5 to 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 first 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 23 of the air duct 20 opens on the water pan 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. 5, the heat exchanger 40 may be disposed inside the air duct 20 and mounted on the water tray 203. The heat exchanger 40 may be 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 23 respectively. The inverted v-shaped structure of the heat exchanger 40 can make the heat exchange area large enough, and make the contact with the air flow flowing upwards from the air inlet 23 more sufficient, and the heat exchange efficiency is higher. The water pan 203 is used for carrying the heat exchanger 40 on one hand and receiving condensed water dropping from the surface of the heat exchanger 40 during air conditioning and 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 13 may be opened at the lower portion of the housing 10, for example, as shown in fig. 7, the air inlets 13 are opened at the rear side of the housing 10. The blower 50 may be installed below the air duct 20 to face the air inlet 23 so as to blow the air flow entering the lower space of the housing 10 from the air inlet 13 toward the inside of the air duct 20. The fan 50 may be a double suction centrifugal fan as shown in fig. 6, or may be another type of fan. It will be appreciated that when the fan 50 is a double suction centrifugal fan, a volute 51 and a motor 52 are provided in association.
In addition, other air supply ports can be arranged on the shell 10 to be matched with the first air supply port 11 for use, so that various air supply modes can be realized. For example, as shown in fig. 5 to 7, the air duct 20 has two second air outlets 22. The casing 10 has two second supply ports 12 to match with the two second air outlets 22, respectively. Two second blowing ports 12 are opened at both lateral sides of the casing 10, respectively. For example, the first air blowing port 11 may be a circular port opened on the front side of the upper portion of the casing 10, the first air outlet 21 may be a circular port opened on the front side of the upper portion of the air duct 20, and the two second air blowing ports 12 may be located in the middle or lower portion of the casing 10, so that the air blown from each air blowing port is staggered in the vertical direction and the left-right direction, thereby providing an air blowing effect, further dispersing the air flow, and improving the cooling/heating speed and the air flow comfort of the indoor unit of the floor air conditioner. Each second air supply outlet 12 can be long-strip-shaped, the length direction of each second air supply outlet is arranged along the vertical direction, air supply is facilitated to the oblique lower side of each second air supply outlet, heating is achieved, blowing is accelerated, and heating comfort is improved. An air guide mechanism may be installed at each second air blowing opening 12, for example, as shown in fig. 7, and an air guide plate 60 having an axis extending in a vertical direction may be installed at each second air blowing opening 12 so as to rotatably guide the air blowing direction.
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. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
