Description

Technical Field

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

[0002] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners consist of an indoor heat exchanger, an outdoor heat exchanger, a compressor, a throttling device, and other necessary components including a dryer and a four-way valve to form a vapor compression refrigeration cycle system, which outputs cold / hot air through a cross-flow fan to achieve cooling and heating of the indoor environment.

[0003] The vertical air conditioner indoor unit is a common indoor unit of air conditioners. When the air conditioner is in cooling operation, the temperature of the fan, heat exchanger and other components of the vertical air conditioner indoor unit is low, and the surrounding air condenses on the surface of the components to produce condensed water. If the condensed water is not properly guided, it may be blown into the indoor environment with the air flow, forming a blown water.

[0004] In the prior art, a water pan is usually set under the fan and heat exchanger to receive the condensed water from the fan and heat exchanger, and then the water in the water pan is centrally processed to prevent it from dripping to the bottom of the casing. However, technicians have found that even so, some condensed water will still accumulate at the bottom of the casing. Utility Model Content

[0005] The purpose of the utility model is to provide a vertical air-conditioning indoor unit which overcomes the above problems or at least partially solves the above problems.

[0006] The utility model aims to solve the problem of incomplete collection of condensed water in the vertical air-conditioning indoor unit of the prior art.

[0007] In order to solve the above technical problems, the utility model provides a vertical air conditioner indoor unit, which includes:

[0008] A casing having an air inlet grille, wherein the air inlet grille is used to allow indoor air to enter the interior of the casing through the air inlet grille;

[0009] a heat exchanger, disposed in the housing, for exchanging heat with the airflow passing therethrough to form a heat exchange airflow;

[0010] A first water receiving tray, arranged below the heat exchanger, for receiving condensed water generated by the heat exchanger;

[0011] A second water receiving pan, disposed at a side end of the heat exchanger, for receiving condensed water at the side end of the heat exchanger and draining the condensed water to the first water receiving pan; and

[0012] The third water receiving tray is arranged on the inner side of the air inlet grille, and is used to receive the condensed water on the inner side of the air inlet grille and discharge the condensed water to the second water receiving tray.

[0013] Optionally, the second water receiving pan is used to receive condensed water from the refrigerant pipe at the side end of the heat exchanger.

[0014] Optionally, the second water receiving tray includes a second bottom wall and a second enclosure wall extending upward from an edge of the second bottom wall, and the refrigerant pipe penetrates the second bottom wall and maintains a seal with the second bottom wall.

[0015] Optionally, the second water receiving tray includes a second bottom wall and a second enclosure wall extending upward from an edge of the second bottom wall;

[0016] The second enclosure wall is provided with a second opening, and the second opening is located directly above the first water receiving tray.

[0017] Optionally, the second enclosure wall has two second opening walls extending outward and parallel to each other, and the second opening is defined between the two second opening walls.

[0018] Optionally, the bottom end of each of the second opening walls is at a height position lower than the bottom surface of the second bottom wall.

[0019] Optionally, the third water receiving tray includes a third bottom wall and a third enclosure wall extending upward from an edge of the third bottom wall;

[0020] The third enclosure wall is provided with a third opening, and the third opening is located directly above the second water receiving tray.

[0021] Optionally, the third enclosure wall has two third opening walls extending outward and parallel to each other, and the third opening is defined between the two third opening walls.

[0022] Optionally, the bottom end of each of the third opening walls is at a height position lower than the bottom surface of the third bottom wall.

[0023] Optionally, the third enclosure wall is arranged to fit the inner surface of the air inlet grille.

[0024] The inventor of the utility model found that in the existing vertical air conditioner indoor unit, the inner side of the air inlet grille is also prone to produce some condensed water, which is often ignored because it is the air inlet side. The condensed water on the side of the heat exchanger, in particular, cannot be effectively collected, especially the condensed water on some refrigerant pipes on the side of the heat exchanger cannot drip into the water receiving tray below the heat exchanger and cannot be collected.

[0025] To this end, the vertical air conditioner indoor unit of the utility model is provided with a first water receiving pan, a second water receiving pan and a third water receiving pan. The first water receiving pan is arranged below the heat exchanger, and is used to receive the condensed water generated by the heat exchanger. The second water receiving pan is arranged at the side end of the heat exchanger, and is used to receive the condensed water at the side end of the heat exchanger and discharge the condensed water to the first water receiving pan. The third water receiving pan is arranged on the inner side of the air inlet grille, and is used to receive the condensed water inside the air inlet grille and discharge the condensed water to the second water receiving pan.

[0026] By setting up three water collection trays, the condensed water on the inner side of the air inlet grille, the side end components of the heat exchanger such as the refrigerant pipe and the heat exchanger itself can be collected and concentrated, which is convenient for subsequent discharge to the main water collection tray or centralized treatment.

[0027] Furthermore, in the vertical air conditioner indoor unit of the utility model, the second enclosure wall has two second opening walls extending outward and parallel to each other, a second opening is defined between the two second opening walls, and the bottom end height position of each second opening wall is lower than the bottom surface of the second bottom wall, so as to ensure that the condensed water flows outward along the two second opening walls and does not flow to the bottom surface of the second bottom wall. Because not all areas of the bottom surface of the second bottom wall are directly above the first water receiving tray, if the condensed water flows to the bottom surface of the second bottom wall and then drips downward, it may not drip into the first water receiving tray.

[0028] Similarly, in the vertical air conditioner indoor unit of the utility model, the third enclosure wall has two third opening walls extending outward and parallel to each other, a third opening is defined between the two third opening walls, and the bottom end height position of each third opening wall is lower than the bottom surface of the third bottom wall, so as to ensure that the condensed water flows outward along the two third opening walls and does not flow to the bottom surface of the third bottom wall. Because not all areas of the bottom surface of the third bottom wall are directly above the second water receiving tray, if the condensed water flows to the bottom surface of the third bottom wall and then drips downward, it may not drip into the second water receiving tray.

[0045] The utility model provides a vertical air-conditioning indoor unit.

[0046] 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.

[0047] 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.

[0048] Figure 1 It is a structural schematic diagram of a vertical air-conditioning indoor unit 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 is shown; Figure 3 yes Figure 2 A magnified image of point A; Figure 4 yes Figure 2 Schematic diagram of the decomposition.

[0049] Please refer to Figures 1 to 4 The vertical air-conditioning indoor unit 100 of the embodiment of the present invention may generally include: a casing 10 , a heat exchanger 80 , a first water receiving tray 50 , a second water receiving tray 30 and a third water receiving tray 20 .

[0050] The housing 10 has an air inlet grille 12, which is used to allow indoor air to enter the housing 10 through the air inlet grille 12. For example, the air inlet grille 12 is in the shape of a grille plate and has a plurality of densely arranged grille holes, through which indoor air enters the housing 10. The housing 10 may also have an air outlet panel 11 (e.g., Figure 1 ), the air outlet panel 11 is provided with an air outlet 112. The air outlet panel 11 and the air inlet grille 12 are both components of the housing 10.

[0051] The housing 10 is provided with an air outlet 112 for blowing out the heat exchange airflow inside the housing 10. The heat exchanger 80 is disposed inside 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.

[0052] The heat exchanger 80, the throttling device, the compressor, the outdoor heat exchanger 80 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.

[0053] For a heat pump air conditioner, the vapor compression refrigeration cycle system also includes a four-way valve for switching the air conditioner between a cooling mode and a heating mode.

[0054] For the heat pump air conditioner, in cooling mode, the heat exchanger 80 functions as an evaporator, and in heating mode, the heat exchanger 80 functions as a condenser.

[0055] 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.

[0056] A fan (not shown) may also be provided in the housing 10, and the fan is provided in the housing 10 to promote the heat exchange air flow to be blown out through the air outlet 112 to adjust the temperature of the indoor environment. The housing 10 is generally in the shape of an upright column as a whole, and its cross section may be square, rectangular, cylindrical, elliptical or other shapes. The air inlet may be provided at the back of the housing 10, that is, on the air inlet grille 12. The air outlet 112 may be provided at the front of the housing 10.

[0057] In some embodiments, the fan 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 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 to the air outlet 112.

[0058] 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.

[0059] When the air conditioner is in cooling operation, the temperature of components such as the fan and heat exchanger 80 of the vertical air conditioner indoor unit 100 is relatively low, and the surrounding air condenses on the surface of the components to produce condensed water. If the condensed water is not treated, it will eventually accumulate at the bottom of the casing 10 or be blown to the indoor environment with the air flow, causing water blowing and affecting the user's wind experience.

[0060] The first water receiving tray 50 is disposed below the heat exchanger 80 to receive condensed water generated by the heat exchanger 80. The first water receiving tray 50 may be in the shape of a tray, and includes a bottom wall and a first enclosure wall extending upward from the periphery of the first 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] like Figure 2 and Figure 3 As shown, the first water receiving tray 50 can be in a long strip shape matching the bottom shape of the heat exchanger 80 .

[0062] The bottom end portion of the heat exchanger 80 may be entirely inserted into the first water receiving tray 50 , so that all condensed water of the heat exchanger 80 falls into the first water receiving tray 50 .

[0063] The second water receiving pan 30 is disposed at a side end of the heat exchanger 80 , and is used to receive condensed water at the side end of the heat exchanger 80 and discharge the condensed water to the first water receiving pan 50 .

[0064] For example, the side end of the heat exchanger 80 often has some refrigerant pipes 81, which are not part of the heat exchanger 80 and are used to connect with the pipelines of the heat exchanger 80. When the air conditioner is cooling, condensed water is often generated on these refrigerant pipes 81, which will gradually accumulate and eventually drip on the bottom of the casing 10.

[0065] In the embodiment of the utility model, the second water receiving pan 30 can be used to receive the condensed water of the refrigerant pipe 81 at the side end of the heat exchanger 80 to prevent the condensed water from finally accumulating at the bottom of the casing 10 .

[0066] Furthermore, the refrigerant pipe 81 also has the function of supporting the second water receiving tray 30. The second water receiving tray 30 can be fixed to the refrigerant pipe by means of a clamping connection or the like.

[0067] The third water receiving tray 20 is disposed on the inner side of the air inlet grille 12 , and is used to receive condensed water on the inner side of the air inlet grille 12 and discharge the condensed water to the second water receiving tray 30 .

[0068] The inventor of the utility model found that in the existing vertical air conditioner indoor unit, some condensation water is also easily generated on the inner side of the air inlet grille 12. Since this part is the air inlet side, the condensation water problem is often ignored and has not been effectively solved.

[0069] In addition, the condensed water on the side end of the heat exchanger 80 cannot be effectively collected, especially some refrigerant pipes 81 on the side end of the heat exchanger 80 are not directly above the first water receiving tray 50 below the heat exchanger 80. The condensed water cannot drip into the first water receiving tray 50 below the heat exchanger 80 and cannot be collected, and will eventually drip to the bottom of the casing 10.

[0070] To this end, the vertical air conditioner indoor unit of the embodiment of the utility model is provided with a first water receiving pan 50, a second water receiving pan 30 and a third water receiving pan 20. The first water receiving pan 50 is arranged below the heat exchanger 80, and is used to receive the condensed water generated by the heat exchanger 80. The second water receiving pan 30 is arranged at the side end of the heat exchanger 80, and is used to receive the condensed water at the side end of the heat exchanger 80 and discharge the condensed water to the first water receiving pan 50. The third water receiving pan 20 is arranged on the inner side of the air inlet grille 12, and is used to receive the condensed water inside the air inlet grille 12 and discharge the condensed water to the second water receiving pan 30.

[0071] The embodiment of the utility model realizes the collection and concentration of condensed water on the inner side of the air inlet grille 12, the side end parts of the heat exchanger 80 such as the refrigerant pipe 81, and the heat exchanger 80 itself by setting three water collection trays, so as to facilitate the subsequent discharge to the general water collection tray or centralized treatment without accumulation at the bottom of the casing 10.

[0072] Some solutions may directly use a general water receiving tray to receive the condensed water of all components in the housing 10. However, since the general water receiving tray is located at a lower position, some condensed water drips from a high place, which easily produces a large dripping noise. In the embodiment of the utility model, multiple water receiving trays are arranged in sequence from top to bottom, and the water dripping travel is shorter and the noise is smaller.

[0073] Figure 5 yes Figure 2 A schematic structural diagram of the third water receiving tray 20; Figure 6 yes Figure 2 A schematic structural diagram of the second water receiving tray 30 in FIG.

[0074] In some embodiments of the present invention, Figure 3and Figure 6 As shown, the second water receiving tray 30 includes a second bottom wall 21 and a second enclosure wall 22 extending upward from the edge of the second bottom wall 21 . The refrigerant pipe 81 penetrates the second bottom wall 21 and maintains a seal with the second bottom wall 21 .

[0075] For example, the second bottom wall 21 may be provided with a through hole (not shown), and the refrigerant pipe 81 may penetrate the through hole to continue to extend. The outer wall of the refrigerant pipe 81 and the inner wall of the through hole may be sealed to prevent water leakage. The specific sealing measures are well known to those skilled in the art and will not be described in detail here.

[0076] The number of the refrigerant tubes 81 may be multiple, and accordingly, the second bottom wall 21 may be provided with multiple through holes, and each refrigerant tube 81 passes through one through hole.

[0077] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the second water receiving tray 30 includes a second bottom wall 21 and a second enclosure wall 22 extending upward from the edge of the second bottom wall 21. A second opening 222 is provided on the second enclosure wall 22, and the second opening 222 is located directly above the first water receiving tray 50 to facilitate drainage toward the first water receiving tray 50. The second water receiving tray 30 can be located directly above the first water receiving tray 50, or can be located obliquely above the first water receiving tray 50.

[0078] Specifically, Figure 6 As shown, the second enclosure wall 22 has two second opening walls 220 extending outward and parallel to each other, and a second opening 222 is defined between the two second opening walls 220. The two second opening walls 220 can guide the condensed water in a direction away from the second water receiving tray 30 body.

[0079] In addition, if Figure 6 As shown, it is preferred that the bottom end height position of each second opening wall 220 is lower than the bottom surface of the second bottom wall 21. In other words, the bottom end of the second opening wall 220 protrudes downward from the bottom surface of the second bottom wall 21.

[0080] In the vertical air conditioner indoor unit of the embodiment of the utility model, the second enclosure wall 22 has two second opening walls 220 extending outward and parallel to each other. A second opening 222 is defined between the two second opening walls 220, and the bottom end height position of each second opening wall 220 is lower than the bottom surface of the second bottom wall 21, so as to ensure that condensed water flows outward along the two second opening walls 220 and does not flow to the bottom surface of the second bottom wall 21.

[0081] Because the inventors found that not all areas of the bottom surface of the second bottom wall 21 are directly above the first water receiving tray 50, if condensed water flows to the bottom surface of the second bottom wall 21 and then drips downward, it may not drip into the first water receiving tray 50. The embodiment of the utility model solves this problem.

[0082] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the third water receiving tray 20 includes a third bottom wall 31 and a third enclosure wall 32 extending upward from the edge of the third bottom wall 31. The third enclosure wall 32 is provided with a third opening 322, which is located directly above the second water receiving tray 30 to facilitate water dripping toward the second water receiving tray 30.

[0083] The third water receiving tray 20 may be located directly above the second water receiving tray 30 , or may be located obliquely above the second water receiving tray 30 .

[0084] like Figure 5 As shown, in some embodiments, the third enclosure wall 32 has two third opening walls 320 extending outward and parallel to each other, and a third opening 322 is defined between the two third opening walls 320. The two third opening walls 320 can guide the condensed water away from the third water receiving tray 20 body.

[0085] In addition, if Figure 5 As shown, it is preferred that the bottom end height position of each third opening wall 320 is lower than the bottom surface of the third bottom wall 31. In other words, the bottom end of the third opening wall 320 protrudes downward from the bottom surface of the third bottom wall 31.

[0086] In the embodiment of the utility model, the third enclosure wall 32 has two third opening walls 320 extending outward and parallel to each other, and a third opening 322 is defined between the two third opening walls 320, and the bottom end height position of each third opening wall 320 is lower than the bottom surface of the third bottom wall 31, so as to ensure that the condensed water flows outward along the two third opening walls 320 and does not flow to the bottom surface of the third bottom wall 31. Because not all areas of the bottom surface of the third bottom wall 31 are directly above the second water receiving tray 30, if the condensed water flows to the bottom surface of the third bottom wall 31 and then drips downward, it may not drip into the second water receiving tray 30. The embodiment of the utility model solves this problem.

[0087] In some embodiments of the present invention, Figure 3 As shown, the third enclosure wall 32 is arranged to fit the inner surface of the air inlet grille 12 to better collect condensed water on the inner surface of the air inlet grille 12, so that there is no gap between the third enclosure wall 32 and the inner surface of the air inlet grille 12, thereby preventing condensed water from leaking out through such gap.

[0088] In some embodiments of the present invention, Figure 3 As shown, the third water receiving tray 20 can be made into a long strip extending along the width direction of the air inlet grille 12 to cover a wider width of the air inlet grille 12 so that condensed water in a larger area of ​​the air inlet grille 12 can fall into the third water receiving tray 20 .

[0089] In some embodiments of the present invention, one second water receiving tray 30 may be provided, or two second water receiving trays 30 may be provided, for example, one second water receiving tray 30 is provided at each of the two lateral ends of the heat exchanger 80 .

[0090] The number of the third water receiving tray 20 may be one or more.

[0091] In some embodiments of the present invention, the third water receiving tray 20 and the air inlet grille 12 may be formed as an integral piece.

[0092] In some embodiments of the present invention, the third water receiving tray 20 can be an independent component from the air inlet grille 12, and the third water receiving tray 20 is fixed to the air inlet grille 12 by means of screws, clamping, bonding, etc.

[0093] 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.
