[0044] The utility model provides a vertical air-conditioning indoor unit.

[0045] The indoor unit of a vertical air conditioner is the indoor part of a split vertical air conditioner or the indoor terminal model of a central air conditioner. It is used to regulate the indoor air. Specifically, it includes regulating the air temperature, humidity, air quality, humidifying, dehumidifying the indoor air, introducing fresh air, etc.

[0046] The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary components to form a vapor compression refrigeration cycle system, which can output cold air / hot air through a fan to achieve cooling and heating of the indoor environment.

[0047] Figure 1 is a structural schematic diagram of a vertical air-conditioning indoor unit 100 according to an embodiment of the utility model; Figure 2 yes Figure 1 A schematic diagram of some components inside the casing 10 of the vertical air conditioner indoor unit 100 is shown; Figure 3 yes Figure 2 A schematic diagram of the assembly structure of the middle housing 10, the first water receiving tray 50, and the second water receiving tray 30; Figure 4 It is a schematic diagram of the exploded structure of the housing 10 , the first water receiving tray 50 , and the second water receiving tray 30 .

[0048] like Figures 1 to 4 As shown, the vertical air-conditioning indoor unit 100 of the embodiment of the present invention may generally include a casing 10 , a heat exchanger (not shown in the figure), a fan 60 , a first water receiving tray 50 and a second water receiving tray 30 .

[0049] The housing 10 is provided with an air outlet 112 for blowing out the heat exchange airflow inside the housing 10. The heat exchanger is arranged in the housing 10 for exchanging heat with the airflow passing therethrough to form a heat exchange airflow. Specifically, when the air conditioner is in cooling mode, the heat exchange airflow is a cold airflow. When the air conditioner is in heating mode, the heat exchange airflow is a hot airflow.

[0050] The fan 60 is disposed in the housing 10 to force the heat exchange air to be blown out through the air outlet 112 .

[0051] In some embodiments, Figure 2 As shown, the fan 60 is a crossflow fan. For a vertical air conditioner indoor unit, the axis of the crossflow fan can be extended in the vertical direction, and the whole is in a vertical column shape. The fan 60 is also equipped with a crossflow air duct. The outlet of the crossflow air duct is connected to or faces the air outlet 112, so as to guide the airflow of the fan 60 to the air outlet 112.

[0052] like Figure 2 As shown, a duct water receiving tray 81 is also provided at the bottom of the cross-flow duct for receiving condensed water from the fan 60. The duct water receiving tray 81 has a drainage notch 811, and the drainage notch 811 is located directly above the first water receiving tray 50 or the second water receiving tray 30 for draining water to the first water receiving tray 50 or the second water receiving tray 30. The figure illustrates a solution in which the drainage notch 811 is located directly above the first water receiving tray 50.

[0053] In other embodiments, the fan may also be a centrifugal fan, an axial flow fan, a laminar flow fan or other types of fans. Of course, different types of fans will also be configured with corresponding types of air ducts, and the types of fans of the utility model are not limited to this.

[0054] like Figure 2 As shown, the housing 10 includes a front panel 11, and the outer surface of the front panel 11 constitutes the front appearance of the vertical air conditioner indoor unit. An air outlet 112 is opened on the front panel 11 to supply air to the front of the vertical air conditioner indoor unit.

[0055] The heat exchanger, the throttling device, the compressor, the outdoor heat exchanger and other refrigeration elements arranged in the outdoor unit of the air conditioner are connected through pipelines to form a vapor compression refrigeration cycle system. The compressor is usually a rolling rotor compressor. The throttling device may include a capillary tube and an electronic expansion valve. For a heat pump air conditioner, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between the cooling mode and the heating mode.

[0056] For heat pump air conditioners, in cooling mode, the heat exchanger acts as an evaporator, and in heating mode, the heat exchanger acts as a condenser.

[0057] The housing 10 may be provided with an air inlet (not shown) for introducing indoor air. The housing 10 also defines an air duct 80. Under the action of the fan 60, the indoor air enters the interior of the housing 10 through the air inlet, completes forced convection heat exchange with the heat exchanger, forms a heat exchange airflow, is guided by the air duct 80, and is blown out from the outlet of the air duct 80.

[0058] The housing 10 is generally in the shape of an upright column, and its cross section may be square, rectangular, cylindrical, elliptical or other shapes. The air inlet may be disposed at the back of the housing 10 , and the air outlet 112 may be disposed at the front of the housing 10 .

[0059] When the air conditioner is in cooling operation, the temperature of the fan 60, the heat exchanger and other components of the vertical air conditioner indoor unit 100 is relatively low, and the surrounding air condenses on the surface of the components to generate condensed water.

[0060] The first water receiving tray 50 is disposed below the heat exchanger and the fan 60 to receive the condensed water generated by the two. The first water receiving tray 50 may be in the shape of a tray, and includes a bottom wall and a retaining wall 32 extending upward from the periphery of the bottom wall. The first water receiving tray 50 may have a drainage hole to drain the water therein. The first water receiving tray 50 may be directly or indirectly mounted on the housing 10 or other components.

[0061] The second water receiving tray 30 is arranged on the inner side of the casing 10 and is located directly below the air outlet 112, and has a water outlet 301 facing the first water receiving tray 50 to allow condensed water at the air outlet 112 to flow from the inner side of the casing 10 to the second water receiving tray 30, and then flow to the first water receiving tray 50 through the water outlet 301.

[0062] Specifically, the water outlet 301 can be located directly above the first water receiving tray 50, and the water flows out of the water outlet 301 and drips into the first water receiving tray 50 by its own gravity. Alternatively, a drain pipe can be connected to the water outlet 301, and the condensed water can be guided to the first water receiving tray 50 by the drain pipe. If a drain pipe is provided, the water outlet 301 of the second water receiving tray 30 may not be provided directly above the first water receiving tray 50, but may be provided obliquely above.

[0063] The vertical air conditioner indoor unit 100 of the embodiment of the utility model is provided with a first water receiving pan 50 and a second water receiving pan 30. The first water receiving pan 50 is arranged below the heat exchanger and the fan 60, and is used to receive the condensed water generated by the two. The second water receiving pan 30 is arranged on the inner side of the casing 10 and is located directly below the air outlet 112, and has a water outlet 301 facing the first water receiving pan 50, so as to allow the condensed water at the air outlet 112 to flow from the inner side of the casing 10 to the second water receiving pan 30, and then flow to the first water receiving pan 50 through the water outlet 301, and finally be discharged through the first water receiving pan 50. In this way, the condensed water on the inner side of the casing 10 is effectively collected and will not accumulate at the bottom of the casing 10.

[0064] Some solutions may directly use the first water receiving tray 50 to receive all the condensed water in the housing 10. However, due to the low position of the first water receiving tray 50, some condensed water drips from a high place, which easily generates a large dripping noise. The embodiment of the utility model adds a second water receiving tray 30, and the position of the second water receiving tray 30 is higher than the first water receiving tray 50. The second water receiving tray 30 first receives the condensed water in the area near the air outlet 112, and then discharges the condensed water to the first water receiving tray 50, so as to avoid water drops directly hitting the first water receiving tray 50 and causing a large noise.

[0065] In some embodiments of the present invention, Figures 2 to 4 As shown, at least one water guide groove 20 is provided on the inner side of the casing 10. Each water guide groove 20 is located on a lateral side of the air outlet 112 and extends in a vertical direction to allow condensed water on the inner side of the casing 10 to flow downward along the water guide groove 20 and flow out of the water guide groove 20 to the second water receiving tray 30.

[0066] The number of the water guide groove 20 can be one or more. Figure 2 and Figure 3 As shown, the number of the water guide grooves 20 can be two. Of course, three, four, five or more water guide grooves 20 can also be provided.

[0067] Alternatively, in some other embodiments, the inner side of the housing 10 may be provided with a plurality of vertical ridges, and a water guide groove may be formed between every two adjacent ridges. The plurality of vertical ridges may form an integrally formed integral part with the housing 10.

[0068] The vertical air-conditioning indoor unit 100 of the embodiment of the utility model is provided with a water guide groove 20 on the inner side of the casing 10 , which can better guide the condensed water on the inner side of the casing 10 into the second water receiving tray 30 .

[0069] Furthermore, the water guide grooves 20 can be further arranged on both sides of the air outlet 112 where the most condensed water is generated, so as to ensure that all the condensed water can flow into the second water receiving tray 30. Figure 2 and Figure 3 As shown, the inventors found that the condensation water is the most in the areas on both sides of the air outlet 112, while the condensation water in other areas is very little. Therefore, the embodiment of the utility model specifically provides two water guide grooves 20, which are respectively located on both sides of the air outlet 112, so as to focus on collecting the condensation water in these two areas.

[0070] In some embodiments of the present invention, Figure 3 As shown, each water guide channel 20 may include a main body section 21 and a water outlet section 22 .

[0071] The main body section 21 extends in the vertical direction and fits the inner side of the housing 10. The water outlet section 22 is bent outward from the lower end of the main body section 21, and the outlet of the water outlet section 22 is located directly above the second water receiving tray 30 so as to discharge water toward the second water receiving tray 30. Considering that the main body section 21 fits the inner side of the housing 10, it is difficult to be located directly above the second water receiving tray 30. For this reason, the water outlet section 22 is bent outward from the lower end of the main body section 21 so that the water outlet section 22 can be better located directly above the second water receiving tray 30.

[0072] The outlet section 22 and the main section 21 may be at a right angle. Alternatively, the outlet section 22 may be at an obtuse angle, that is, the outlet section 22 may extend downwardly. Alternatively, the outlet section 22 and the main section 21 may be at an arc transition, so that the water flow turns more gently from the main section 21 to the outlet section 22.

[0073] In some embodiments of the present invention, Figure 3 As shown, the water guide groove 20 includes a groove bottom wall 211 and two groove side walls 212. The groove bottom wall 211 is used to fit the inner side of the housing 10. The two groove side walls 212 extend outward from both ends of the groove bottom wall 211 in the width direction. The angle between the groove side wall 212 and the groove bottom wall 211 can be a right angle, an acute angle or an obtuse angle, for example Figure 3 The water guide groove 20 and the housing 10 can be an integrally formed unit.

[0074] Furthermore, in some embodiments of the present invention, the slot bottom wall 211 may be the housing 10 itself, and the two slot side walls 212 may extend from the inner side surfaces of the housing 10 respectively.

[0075] In some embodiments of the present invention, the slot sidewall 212 and the housing 10 may be an integrally formed unitary piece.

[0076] In some other embodiments of the present invention, the water guide groove 20 may also be an independent component from the housing 10, and the water guide groove 20 is installed on the housing 10 by means of snap connection, screw connection or bonding.

[0077] In some embodiments of the present invention, Figure 3 As shown, the number of the water guide grooves 20 can be two, and the two water guide grooves 20 are respectively located on two lateral sides of the air outlet 112 .

[0078] At the same time, the second water receiving tray 30 includes a bottom wall 31 and a surrounding wall 32, the surrounding wall 32 extends upward from the periphery of the bottom wall 31, and the surrounding wall 32 is provided with two water outlets 301 arranged in a transverse direction. Figure 3 As shown, the enclosure wall 32 is configured as a discontinuous structure having two notches, and the two notches constitute two water outlets 301 .

[0079] In this way, the lower end of the water channel 20 is closer to the water outlet 301 of the second water receiving tray 30. When the amount of water in the water channel 20 is large, it can be discharged from the water outlet 301 in time to avoid a large amount of condensed water accumulating in the second water receiving tray 30 in a short time and causing water overflow.

[0080] In some embodiments of the present invention, the enclosure wall 32 of the second water receiving tray 30 is closely fitted to the inner side of the casing 10 , so that water flowing downward along the inner side of the casing 10 can flow into the second water receiving tray 30 along the enclosure wall 32 .

[0081] In some embodiments of the present invention, Figure 3 As shown, the size of the second water receiving tray 30 in the lateral direction is made larger than the width of the air outlet 112, and the downward projection of the air outlet 112 falls completely on the second water receiving tray 30, so that the condensed water in the areas on both sides of the air outlet 112 can fall completely into the second water receiving tray 30 and will not spill to the bottom of the casing 10.

[0082] Furthermore, the second water receiving tray 30 can cover the entire width of the front panel 11 in the lateral direction.

[0083] In some embodiments of the present invention, the bottom wall 31 of the second water receiving tray 30 can be an inclined surface (not a horizontal surface) so that the water outlet 301 is lower than other positions, so that the condensed water therein can flow to the water outlet 301 more smoothly under the action of gravity.

[0084] In other embodiments of the present invention, the bottom wall 31 of the second water receiving tray 30 can be funnel-shaped so that the water outlet 301 is located lower than other positions, so that the condensed water therein can flow to the water outlet 301 more smoothly under the action of gravity.

[0085] In some embodiments of the present invention, Figure 3 As shown, a notch 501 may be provided on one side of the first water receiving tray 50 facing the housing 10 to accommodate the bottom of the second water receiving tray 30 .

[0086] Figure 5 yes Figure 4 Another perspective schematic diagram of the first water receiving tray 50.

[0087] In some embodiments of the present invention, Figures 3 to 5 As shown, the first water receiving tray 50 and the second water receiving tray 30 are connected to the housing 10 by the same set of screws (not shown). In this way, the connection structure can be simplified as much as possible, and the structural design and installation process of related components can be simplified.

[0088] Specifically, Figure 4 and Figure 5As shown, at least one first through hole 1150 can be formed on the housing 10, and the second water receiving tray 30 has at least one orifice plate 35 extending downward, and each orifice plate 35 has a second through hole 352. At least one threaded hole 510 is formed on the first water receiving tray 50, and each first through hole 1150 is opposite to a second through hole 352 and a threaded hole 510, so that a screw passes through the first through hole 1150 and the second through hole 352 in sequence to be tightened in the threaded hole 510.

[0089] For example Figure 4 As shown, the number of the first through holes 1150 can be two, and the two first through holes 1150 are arranged side by side along the transverse direction of the housing 10. Accordingly, the number of the orifice plates 35 is two, and each orifice plate 35 is provided with a second through hole 352. The number of the threaded holes 510 is also two.

[0090] Of course, three, four or more first through holes 1150 may also be provided to make the positions of the first water receiving tray 50 and the second water receiving tray 30 more stable.

[0091] Furthermore, in some embodiments, Figure 4 As shown, at least one hole column 115 extends from the inner side of the housing 10, and each first through hole 1150 is opened on the inner side of a hole column 115. Considering that the housing 10 is usually thin, in order to enhance the strength of the threaded connection and make the positions of the first water receiving tray 50 and the second water receiving tray 30 more stable, in this embodiment, the first through hole 1150 is particularly opened on the hole column 115. The hole column 115 and the housing 10 can be an integrally formed integral part.

[0092] Furthermore, in some embodiments, Figure 4 As shown, each first through hole 1150 is provided with a thread to enhance the connection strength and make the positions of the first water receiving tray 50 and the second water receiving tray 30 more stable.

[0093] In some embodiments, Figure 4 and Figure 5 As shown, the threaded hole 510 of the first water receiving tray 50 can also be opened on the hole column 115 to enhance the strength of the threaded hole 510.

[0094] 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 that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
