Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to an air-conditioning indoor unit and an air conditioner. Background Art

[0002] Most current air conditioner indoor units include a heat exchanger. This heat exchanger absorbs heat or cold from the indoor air, exchanging heat between the treated air and the room. However, due to the difference between the operating temperature of the heat exchanger and the indoor temperature, the surrounding temperature of the screws that secure the heat exchanger and are in direct contact with it also differs from the indoor temperature. Especially when the indoor unit is operating in cooling mode, the temperature around the screws is too low, which can easily lead to condensation forming around them. This condensation then flows into the air duct and is easily blown out along with the heated air, impacting the user experience. Utility Model Content

[0003] In view of the above problems, the present utility model is proposed to provide an air-conditioning indoor unit and air conditioner that overcome the above problems or at least partially solve the above problems. It can solve the problem that condensation water is easily formed around the screws, and the condensation water is easily blown out along with the heat exchange air after flowing into the air duct, thereby achieving the purpose of improving the user experience.

[0004] Specifically, the utility model provides an air conditioner indoor unit, comprising:

[0005] The frame is vertically arranged and has at least one connecting hole formed thereon for fixing the heat exchanger.

[0006] At least one first drainage rib is integrally formed on a side of the frame away from the heat exchanger. Each of the first drainage ribs corresponds to each of the connection holes. The first drainage rib includes a vertically disposed first section and a second section connected to the bottom of the first section, the second section being inclined downward from the bottom of the first section. The connection hole is located on a lateral side of the first section and above the second section.

[0007] Optionally, the frame includes at least one vertical support column, and the vertical support columns are adjacently and spaced apart and arranged on one side of the air inlet of the air conditioner indoor unit.

[0008] The connecting hole is arranged on the vertical support column, the first section is located on the side of the connecting hole away from the air inlet, and the second section extends from one end of the first section to the edge of the side of the vertical support column close to the air inlet.

[0009] Optionally, the air conditioner indoor unit further includes at least one second drainage rib integrally formed on a side of the frame away from the heat exchanger. Each second drainage rib is spaced below one of the first drainage ribs. The second drainage ribs are arranged at an angle, with one end of the second drainage rib closer to the air inlet being lower than the other end.

[0010] In the extension direction of the second drainage rib, two ends of the second drainage rib are flush with two lateral ends of the vertical support column.

[0011] Optionally, there are multiple connection holes. The air conditioner indoor unit further includes multiple third drainage ribs, each of which is integrally formed on a side of the frame away from the heat exchanger. The third drainage ribs are spaced apart from the first and second drainage ribs. The end of the third drainage rib closest to the air inlet is lower than the other end.

[0012] Optionally, the second drainage rib is arranged in parallel with the third drainage rib.

[0013] Optionally, the frame further comprises a plurality of transverse connecting columns spaced vertically apart, one transverse end of each transverse connecting column being connected to the vertical support column. The upper end surfaces of the connection between the transverse connecting column and the vertical support column are inclined, with the upper end surfaces of the connection between the transverse connecting column and the vertical support column being lower at one end closer to the air inlet than at the other end.

[0014] Optionally, the second section of the first drainage rib and the second drainage rib have the same inclination angle, and the angle between them and the horizontal plane is between 10° and 45°.

[0015] Optionally, a water receiving tray is provided at the bottom of the frame.

[0016] The projection of the first drainage rib in the vertical direction is located inside the water receiving tray.

[0017] Optionally, the heat exchanger is fixedly connected to the frame via a metal fastener, wherein the metal fastener passes through the connection hole and is connected to the heat exchanger.

[0018] The utility model also provides an air conditioner, comprising:

[0019] The above-mentioned air-conditioning indoor unit and air-conditioning outdoor unit, the air-conditioning outdoor unit is connected to the air-conditioning indoor unit.

[0020] In the air-conditioning indoor unit of the present invention, since the condensed water is guided by the first drainage rib, the condensed water is prevented from flowing into the air outlet along the frame, thereby reducing the occurrence of the condensed water being blown out along with the heat exchange air after flowing into the air duct, thereby improving the user experience.

[0021] The first section and the second section are semi-enclosed on the outside of the connecting hole, so that the condensed water flowing down the connecting hole can fully contact the first drainage rib and flow down along the first drainage rib. The semi-enclosed structure does not reduce the drainage effect of the first drainage rib, and simplifies the molding process of the first drainage rib, thereby reducing the production cost of the air-conditioning indoor unit without affecting the quality of the air-conditioning indoor unit.

[0022] Moreover, the first drainage rib protrudes outward from the surface of the frame, so that the first drainage rib can also be used to guide condensed water formed at other parts of the frame.

[0041] Figure 1 FIG. 1 is a schematic structural diagram of a partial structure of an air-conditioning indoor unit according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 5 The embodiment of the present invention provides an air conditioner indoor unit, which includes a frame 100 and at least one first drainage rib 200 .

[0042] The frame 100 is vertically arranged and has at least one connection hole 111 formed thereon for fixing the heat exchanger.

[0043] The first drainage rib 200 is integrally formed on the side of the frame 100 away from the heat exchanger. The first drainage rib 200 corresponds to the connection holes 111. The first drainage rib 200 includes a vertically disposed first section 210 and a second section 220 connected to the bottom of the first section 210. The second section 220 is tilted downward from the bottom of the first section 210. The connection hole 111 is located on one side of the first section 210 and above the second section 220.

[0044] In this embodiment, the connection hole 111 can be a self-drilling hole or a preset hole.

[0045] The air conditioner indoor unit includes a heat exchanger. The heat exchanger is fixedly connected to the frame 100 via fasteners extending through connection holes 111. The fasteners are located within connection holes 111, making it easier for condensation to form there. Condensation formed there falls onto the first drainage ribs 200 and flows downward along them. Because the condensation is guided by the first drainage ribs 200, it is prevented from flowing along the frame 100 into the air outlet. This reduces the risk of condensation entering the air duct and being blown out with the heated air, improving the user experience. The first section 210 and the second section 220 are semi-enclosed on the outside of the connecting hole 111, so that the condensed water flowing down from the connecting hole 111 can fully contact the first drainage rib 200 and flow down along the first drainage rib 200. The semi-enclosed structure neither reduces the drainage effect of the first drainage rib 200 nor simplifies the molding process of the first drainage rib 200, thereby reducing the production cost of the air-conditioning indoor unit without affecting the quality of the air-conditioning indoor unit.

[0046] Moreover, the first drainage rib 200 protrudes outward from the surface of the frame 100 , so that the first drainage rib 200 can also be used to guide condensed water formed at other locations on the frame 100 .

[0047] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the frame 100 includes at least one vertical support column 110. The vertical support columns 110 are adjacently and spaced apart and arranged on one side of the air inlet 600 of the air conditioner indoor unit.

[0048] The connecting hole 111 is provided on the vertical support column 110 , the first section 210 is located on the side of the connecting hole 111 away from the air inlet 600 , and the second section 220 extends from one end away from the first section 210 to the edge of the side of the vertical support column 110 close to the air inlet 600 .

[0049] In this embodiment, a connection hole 111 is provided on the vertical support column 110 for supporting the heat exchanger. The air outlet and the air inlet 600 are spaced apart, and the end of the second section 220 closest to the air inlet 600 is lower than the other end. This allows condensed water flowing from the connection hole 111 to flow along the first guide rib 200 away from the air outlet, allowing the condensed water to flow along the edge of the vertical support column 110 to the lower side of the frame 100, thereby preventing the condensed water from flowing along the frame 100 into the air outlet and, in turn, being blown out along with the heat exchange air after entering the air duct.

[0050] In some embodiments of the present invention, Figure 1 As shown, the air conditioner indoor unit also includes at least one second drainage rib 300, which is integrally formed on the side of the frame 100 away from the heat exchanger. Each second drainage rib 300 is spaced apart and disposed below a first drainage rib 200. The second drainage ribs 300 are arranged in an upward and downwardly inclined manner, with the end of the second drainage rib 300 closer to the air inlet 600 being lower than the other end.

[0051] In the extension direction of the second drainage rib 300 , both ends of the second drainage rib 300 are flush with both lateral ends of the vertical support column 110 .

[0052] In this embodiment, the second drainage rib 300 is integrally formed with the frame 100 , thereby improving the overall structural strength of the frame 100 .

[0053] The second drainage rib 300 is located on the lower side of the first drainage rib 200, and is used to guide the condensed water that is not guided to the edge of the vertical support column 110 by the first drainage rib 200, so that the condensed water is diverted, avoiding the situation where too much condensed water accumulates on the same drainage rib and cannot be fully drained, so as to better guide the condensed water to flow to the edge of the vertical support column 110, and then flow to the lower side of the frame 100.

[0054] In the extension direction of the second drainage rib 300, its two ends are flush with the lateral ends of the vertical support column 110, so that the area of the second drainage rib 300 that can be used to receive the condensation water flowing down from above is increased, thereby improving the guiding effect of the second drainage rib 300 on the condensation water on the frame 100.

[0055] In some embodiments of the present invention, Figure 1 As shown, there are multiple connection holes 111. The air conditioner indoor unit also includes multiple third drainage ribs 400, which are integrally formed on the side of the frame 100 away from the heat exchanger. The third drainage ribs 400 are spaced apart from the first drainage ribs 200 and the second drainage ribs 300. The end of the third drainage rib 400 near the air inlet 600 is lower than the other end.

[0056] In this embodiment, multiple connection holes 111 are provided to ensure a stable connection between the heat exchanger and the frame 100. The third drainage ribs 400 are spaced apart from the first and second drainage ribs 200 and 300, and are angled to better guide condensate to the edges of the vertical support columns 110 and, subsequently, to the underside of the frame 100, enhancing condensate drainage. The third drainage ribs 400 are integrally formed with the frame 100, enhancing the overall structural strength of the frame 100.

[0057] In some embodiments of the present invention, Figure 1 As shown, the second drainage rib 300 and the third drainage rib 400 are arranged in parallel.

[0058] In this embodiment, a third drainage rib 400 is arranged in parallel with the second drainage rib 300, which can not only evenly distribute and guide the condensed water, reduce the situation where too much water accumulates on the same drainage rib, improve drainage efficiency, but also further increase the structural strength of the vertical support column 110.

[0059] Moreover, the parallel arrangement of the second drainage rib 300 and the third drainage rib 400 simplifies the manufacturing process of the air-conditioning indoor unit and also facilitates the maintenance and cleaning of the air-conditioning indoor unit.

[0060] In some embodiments of the present invention, Figure 1As shown, the frame 100 further includes a plurality of transverse connecting columns 120 spaced apart vertically, with one transverse end of the transverse connecting column 120 connected to the vertical support column 110. The upper end surface of the connection between the transverse connecting column 120 and the vertical support column 110 is inclined, with the upper end surface of the connection between the transverse connecting column 120 and the vertical support column 110 being lower at one end closer to the air inlet 600 than at the other end.

[0061] In this embodiment, transverse connecting columns 120 are used to connect the two lateral sides of frame 100 to enhance the structural strength of frame 100 and, in turn, improve the installation stability of the heat exchanger. The connection between transverse connecting columns 120 and vertical support columns 110 is located on the side of the vertical support columns 110 away from the heat exchanger. The upper end surface of the connection between transverse connecting columns 120 and vertical support columns 110 is tilted downward toward the air inlet 600 to prevent condensation from accumulating at the connection between transverse connecting columns 120 and vertical support columns 110. The connection also guides condensation, allowing it to flow along the upper end surface of the connection between transverse connecting columns 120 and vertical support columns 110 to the edge of the vertical support columns 110 and then to the lower side of frame 100.

[0062] In some embodiments of the present invention, the second section 220 of the first drainage rib 200 and the second drainage rib 300 have the same inclination angle, and the angle between them and the horizontal plane is between 10° and 45°.

[0063] In this embodiment, there is an angle between the second section 220 of the first drainage rib 200 and the second drainage rib 300 and the horizontal plane, so that under the action of gravity, the condensed water can flow along the second section 220 of the first drainage rib 200 or the second drainage rib 300 to the edge of the vertical support column 110, and then flow to the lower side of the frame 100.

[0064] The greater the angle between the second section 220 of the first drainage rib 200 and the second drainage rib 300 and the horizontal plane, the greater the flow rate of the condensed water. However, when the width of the vertical support column 110 is constant, the greater the angle between the second section 220 of the first drainage rib 200 and the second drainage rib 300 and the horizontal plane, the longer the second section 220 of the first drainage rib 200 or the second drainage rib 300 needs to be, making the manufacture of the frame 100 more difficult. When the angle between the second section 220 of the first drainage rib 200 and the second drainage rib 300 and the horizontal plane is between 10° and 45°, the condensed water can be ensured to flow at a faster rate while avoiding the manufacturing inconvenience caused by the second section 220 of the first drainage rib 200 and the second drainage rib 300 being too long.

[0065] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, a water receiving tray 500 is provided at the bottom of the frame 100 .

[0066] The vertical projection of the first drainage rib 200 is located inside the water receiving tray 500 .

[0067] In this embodiment, a water receiving pan 500 is provided at the bottom of the frame 100 to collect and store condensed water dripping from components such as the heat exchanger or the frame 100. The vertical projection of the first drainage rib 200 is located within the water receiving pan 500, ensuring that the condensed water is effectively directed into the water receiving pan 500 when the first drainage rib 200 guides the condensed water.

[0068] In some embodiments of the present invention, Figure 1 and Figure 5 As shown, the projection of the second drainage rib 300 in the vertical direction is inside the water receiving tray 500 to ensure that the condensed water is effectively guided into the water receiving tray 500 when the second drainage rib 300 guides the condensed water.

[0069] In some embodiments of the present invention, the vertical projection of the third drainage rib 400 is located inside the water receiving tray 500 to ensure that the condensed water is effectively guided into the water receiving tray 500 when the third drainage rib 400 guides the condensed water.

[0070] In some embodiments of the present invention, the heat exchanger is fixedly connected to the frame 100 by metal fasteners. The metal fasteners pass through the connection holes 111 and are connected to the heat exchanger.

[0071] In this embodiment, the metal fasteners are in direct contact with the heat exchanger, enabling heat transfer between them and the room, resulting in a significant temperature difference between the metal fasteners and the indoor temperature. However, the metal fasteners' high strength and rigidity improve the heat exchanger's installation stability, reducing the risk of excessive noise or even falling off during operation due to loose heat exchanger installation, thereby improving the quality of the air conditioner. Furthermore, the coordination between the connection holes 111 and the metal fasteners simplifies the heat exchanger installation process, improving the efficiency of the air conditioner's indoor unit installation.

[0072] In some embodiments of the present invention, the heat exchanger is an evaporator.

[0073] The embodiment of the present utility model provides an air conditioner. The air conditioner includes an indoor air conditioner and an outdoor air conditioner according to any one of the above embodiments. The outdoor air conditioner is connected to the indoor air conditioner.

[0074] In this embodiment, condensed water formed at the connection hole 111 falls onto the first drainage rib 200 and flows downward along the first drainage rib 200. Because the condensed water is guided by the first drainage rib 200, it is prevented from flowing along the frame 100 into the air outlet. This further reduces the risk of condensed water being blown out along with the heat exchange air after entering the air duct, thereby improving the user experience. The first section 210 and the second section 220 semi-enclose the outside of the connection hole 111, allowing the condensed water flowing from the connection hole 111 to fully contact the first drainage rib 200 and flow downward along the first drainage rib 200. This semi-enclosed structure does not reduce the drainage effect of the first drainage rib 200, but also simplifies the molding process of the first drainage rib 200, reducing the production cost of the air conditioner indoor unit without affecting its quality.

[0075] Moreover, the first drainage rib 200 protrudes outward from the surface of the frame 100 , so that the first drainage rib 200 can also be used to guide condensed water formed at other locations on the frame 100 .

[0076] In some embodiments of the present invention, the air-conditioning indoor unit is a vertical air-conditioning indoor unit.

[0077] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention can be directly determined or deduced from the contents disclosed herein without departing from the spirit and scope of the present invention.
