Description

Technical Field

[0001] This utility model relates to the field of air conditioning systems, and more particularly to an indoor air conditioning unit and an air conditioning system. Background Technology

[0002] In some air conditioners, the unit comprises a casing and a heat exchanger. The heat exchanger is arranged at an angle within the casing, and there is usually a gap between the upper surface of the heat exchanger and the top plate of the casing. To seal this gap, a metal bracket is typically fixed to the inner surface of the top plate by welding or screws, ensuring that the metal bracket has a plane that matches the upper surface of the heat exchanger. A sealing element can then seal the gap between this plane and the upper surface of the heat exchanger. However, this method of installing the metal bracket results in low overall production efficiency for the air conditioner and poor sealing performance. Utility Model Content

[0040] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0041] Please see Figures 1-4 This application provides an indoor air conditioning unit 100, which includes a housing 10, a heat exchanger 20 and a first sealing member 30. The heat exchanger 20 is inclinedly disposed inside the housing 10 and includes an upper end face 21. The upper end face 21 is inclinedly disposed inside the housing 10 and includes a first inclined surface 31 that cooperates with the upper end face 21.

[0042] Thus, the first seal 30 can seal the gap between the upper end face 21 of the heat exchanger 20 and the housing 10, preventing air passing through the heat exchanger 20 from leaking out of the gap and affecting the heat exchange effect of the heat exchanger 20. At the same time, the first seal 30 can also achieve heat insulation. The first inclined surface 31 of the first seal 30 cooperates with the upper end face 21 of the heat exchanger 20, which facilitates the installation of the first seal 30 and thus improves the overall production efficiency of the air conditioning indoor unit 100.

[0043] The housing 10 can be a cuboid structure, and the first sealing element 30 can be set in the angled area formed by the top plate 11 and the back plate of the housing 10. The heat exchanger 20 can be a flat plate heat exchanger 20, and the tilt angle of the heat exchanger 20 can be 30°, 45°, 60°, etc. The tilt degree of the first tilted surface 31 can be the same as the tilt degree of the upper end surface 21.

[0044] Placing the heat exchanger 20 at an angle can reduce the height space occupied by the heat exchanger 20 after installation, making the overall height of the air conditioner indoor unit 100 lower. This is conducive to the miniaturization of the air conditioner indoor unit 100, thereby reducing the weight of the air conditioner indoor unit 10 casing, which is beneficial for the handling and installation of the air conditioner indoor unit 100.

[0045] See also Figure 1 and Figure 2 In some embodiments, the housing 10 includes a top plate 11, and the first seal 30 includes a top surface 32 that abuts against the top plate 11.

[0046] Thus, the top surface 32 of the first sealing element 30 abuts against the top plate 11 of the housing 10, which can seal the gap between the housing 10 and the first sealing element 30, preventing the air passing through the heat exchanger 20 from leaking out from the gap between the top plate 11 and the first sealing element 30, thus affecting the heat exchange effect of the heat exchanger 20.

[0047] Specifically, the top plate 11 refers to the plate-like structure located on the upper side of the housing 10 under normal use. The top surface 32 refers to the surface of the housing 10 facing the top plate 11 under normal use. The top plate 11 of the housing 10 can cover the top surface 32 of the first sealing member 30.

[0048] See also Figure 2 In some embodiments, the first seal 30 is provided with a groove 33 recessed downward from the top surface 32, and the groove 33 extends along the length direction of the first seal 30.

[0049] Thus, the groove 33 can reduce the weight of the first seal 30 and also reduce the amount of material used in the first seal 30, thereby reducing the production cost of the first seal 30.

[0050] Specifically, the groove 33 can be formed during the molding of the first seal 30, or it can be formed after the first seal 30 is molded by removing part of the material. The cross-sectional shape of the groove 33 can be a regular shape such as square, trapezoid, triangle, or circle, or it can be an irregular shape. The length direction of the first seal 30 can be the same as the length direction of the heat exchanger 20.

[0051] In one embodiment, the cross-section of the groove 33 is a right trapezoid, the inclination of the trapezoidal slope in the groove 33 is the same as the inclination of the first inclined surface 31, and the width from the outer surface of the first seal 30 to the groove wall surface corresponding to the groove 33 is equal, so as to reduce the amount of material used in the first seal 30 as much as possible while ensuring the structural strength of the first seal 30.

[0052] See also Figure 2 In some embodiments, the groove 33 is provided with a reinforcing rib 34, which is connected to the groove wall surface of the groove 33.

[0053] Thus, the reinforcing rib 34 can improve the structural strength of the first seal 30, thereby extending the service life of the first seal 30.

[0054] Specifically, the reinforcing rib 34 can be made of foam material. Furthermore, the material of the reinforcing rib 34 can be the same as that of the first sealing member 30, and the reinforcing rib 34 and the first sealing member 30 can be integrally formed. The reinforcing rib 34 can be connected to the top surface 32 of the first sealing member 30.

[0055] See also Figure 2 In some embodiments, the reinforcing ribs 34 connect the two groove walls in the width direction of the groove 33, and there are multiple reinforcing ribs 34, which are arranged at intervals along the length direction of the first seal 30.

[0056] Thus, multiple reinforcing ribs 34 can significantly improve the structural strength of the first seal 30, thereby effectively extending the service life of the first seal 30.

[0057] Specifically, the shape of the reinforcing rib 34 can be the same as the cross-sectional shape of the groove 33. For example, when the cross-sectional shape of the groove 33 is a right trapezoid, the reinforcing rib 34 is a right trapezoid; when the cross-sectional shape of the groove 33 is a triangle, the reinforcing rib 34 is a triangle.

[0058] The number of reinforcing ribs 34 can be 2, 3, 4, 5, 6 or more. Multiple reinforcing ribs 34 cause the first sealing member 30 to form multiple grooves 33. The length of each groove 33 along the length direction of the first sealing member 30 can be the same or different. The number, position, and spacing of the reinforcing ribs 34 can be designed according to actual needs. In this embodiment, the number of reinforcing ribs 34 is 3, and the first sealing member 30 forms 4 grooves 33 of equal length.

[0059] See also Figure 1 and Figure 2 In some embodiments, the top surface 32 is provided with a sealing rib 35, which surrounds the periphery of the top surface 32 and abuts against the top plate 11.

[0060] Thus, the gap between the first sealing element 30 and the top plate 11 can be sealed by the sealing rib 35, thereby enhancing the sealing effect between the heat exchanger 20 and the housing 10.

[0061] Specifically, the material of the sealing rib 35 can be the same as that of the first sealing element 30, the sealing rib 35 can be integrally formed with the first sealing element 30, and the sealing rib 35 can protrude from the top surface 32.

[0062] The sealing rib 35 is arranged around the periphery of the top surface 32, which means that the sealing rib 35 can surround the periphery of the whole formed by multiple grooves 33, that is, the multiple grooves 33 are located in the space enclosed by the sealing rib 35.

[0063] The sealing rib 35 and the top plate 11 can be interference-fitted to improve the sealing performance of the first sealing element 30 and the top plate 11.

[0064] In some embodiments, the height of the sealing rib 35 ranges from 1 mm to 4 mm; and / or the width of the sealing rib 35 ranges from 3 mm to 7 mm.

[0065] Thus, when the size of the sealing rib 35 is within the above range, the sealing effect between the first sealing element 30 and the top plate 11 can be improved.

[0066] Specifically, the height of the sealing rib 35 can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, etc. The width of the sealing rib 35 can be 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, etc.

[0067] In one embodiment, the cross-sectional width of the sealing rib 35 decreases from the top surface 32 toward the direction away from the groove 33. The height of the sealing rib 35 can be the distance from the vertex of the sealing rib 35 to the top surface 32, and the width of the sealing rib 35 can be the distance between the cross-section of the sealing rib 35 and the two connection points of the top surface 32.

[0068] See also Figure 1 and Figure 2 In some embodiments, the housing 10 includes a first side plate 12 and a second side plate 12, and a first sealing member 30 is sandwiched in the enclosed space formed by the first side plate 12, the second side plate 12 and the top plate 11.

[0069] Specifically, the first side plate 12 and the second side plate 12 can be spaced apart at both ends of the top plate 11 along the length of the heat exchanger 20.

[0070] Thus, by clamping the first seal 30 between the first side plate 12 and the second side plate 12, the first seal 30 can be limited in the length direction of the heat exchanger 20, reducing the shaking of the first seal 30 along the length direction, thereby improving the installation stability of the first seal 30.

[0071] See also Figures 3-5 In some embodiments, the first seal 30 includes a body 36 and a first protrusion 37 protruding downward from a first end of the body 36, and the air conditioner indoor unit 100 includes a support 50 disposed on one side of the heat exchanger 20 in the length direction, and the first protrusion 37 abuts against the support 50.

[0072] Thus, the support member 50 can provide support for the first protrusion 37, thereby providing support for the first end of the first seal member 30.

[0073] Specifically, the first protrusion 37 can be integrally formed with the body 36, and the first protrusion 37 can abut against the support member 50 through its bottom surface. The bottom surface of the first protrusion 37 can be a flat surface, or an arc-shaped surface, a wavy surface, a sawtooth surface, etc. The first protrusion 37 can be interference-fitted with the support member 50 to achieve stable support of the first end of the first sealing member 30 by the support member 50.

[0074] See also Figure 2 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the indoor unit 100 of the air conditioner includes a mounting plate 60 and a baffle 13. The mounting plate 60 is disposed on one side of the heat exchanger 20 along its length, and the heat exchanger 20 is mounted on the mounting plate 60. A support member 50 is disposed between the mounting plate 60 and the baffle 13. The ends of the mounting plate 60, the baffle 13 and the support member 50 surround each other to form a slot 61, and a first protrusion 37 is engaged in the slot 61.

[0075] Thus, by engaging the first protrusion 37 in the slot 61, the first protrusion 37 can be fixed in a limited position, and the first seal 30 can be fixed without screws or other mounting parts, making installation simple.

[0076] Specifically, the mounting plate 60 can be formed from metal material through stamping. Figure 8 and Figure 9 The mounting plate 60 can be a bent structure. The mounting plate 60 includes a first bent part 62, a second bent part 63 and a third bent part 64. The second bent part 63 is a right-angled trapezoidal plate structure. The first bent part 62 and the third bent part 64 are both long strip structures. The first bent part 62 and the third bent part 64 are perpendicular to the second bent part 63 and are located on opposite sides of the second bent part 63.

[0077] The hypotenuse of the second bend 63 connects to the first bend 62, and the right-angled side opposite the hypotenuse of the second bend 63 connects to the third bend 64. The first bend 62 is fixedly connected to the heat exchanger 20 by screws or other fasteners. The support member 50 contacts the second bend 63 and the third bend 64, and the third bend 64 is fixedly connected to the support member 50 by screws or other fasteners. The baffle 13 is located on the side of the support member 50 opposite to the second bend 63.

[0078] The upper surface of the support member 50 can be lower than the upper surfaces of the mounting plate 60 and the baffle 13. Therefore, the slot 61 can be formed by the side of the second bend 63, the side of the third bend 64, the side of the baffle 13 and the upper surface of the support member 50. The first protrusion 37 is engaged in the slot 61, that is, the bottom surface of the first protrusion 37 abuts against the upper surface of the support member 50.

[0079] See also Figure 5 and Figure 10 In some embodiments, the first seal 30 includes a body 36 and a second protrusion 38 protruding downward from the second end of the body 36, and the air conditioner indoor unit 100 includes a heat exchanger side plate 22 disposed on one side of the heat exchanger 20 in the length direction, and the second protrusion 38 abuts against the heat exchanger side plate 22.

[0080] Thus, the heat exchanger side plate 22 can provide support for the second protrusion 38, thereby providing support for the second end of the first seal 30. The first protrusion 37 and the second protrusion 38 can effectively prevent the movement of the first seal 30, which helps to enhance the sealing effect between the heat exchanger 20 and the housing 10.

[0081] Specifically, the second protrusion 38 can be integrally formed with the body 36, and the second protrusion 38 can abut against the heat exchanger side plate 22 through the side near the first protrusion 37. The second protrusion 38 can be interference-fitted with the heat exchanger side plate 22 to achieve stable support of the second end of the first seal 30 by the heat exchanger side plate 22.

[0082] See also Figure 4In some embodiments, the indoor unit 100 of the air conditioner includes a first sealing sheet 70 disposed between the upper end face 21 and the first inclined face 31, the first sealing sheet 70 sealing the gap between the first inclined face 31 and the upper end face 21.

[0083] In this way, by sealing the gap between the first sealing element 30 and the upper end face 21 of the heat exchanger 20 by the first sealing piece 70, the sealing performance between the first sealing element 30 and the heat exchanger 20 can be improved, thereby improving the heat exchange effect of the heat exchanger 20.

[0084] Specifically, the material of the first sealing sheet 70 and the first sealing element 30 can be the same or different. For example, both the first sealing sheet 70 and the first sealing element 30 can be made of foam; or, for example, the first sealing element 30 can be made of plastic and the first sealing sheet 70 can be made of sponge. The first sealing sheet 70 can be integrally molded with the first sealing element 30.

[0085] The heat exchanger 20 and the first sealing plate 70 can be interference-fitted to improve the sealing performance of the heat exchanger 20 and the first sealing plate 70.

[0086] In some embodiments, the first sealing element 30 is a foam component. Because foam has thermal insulation properties, the first sealing element 30 can achieve a thermal insulation effect. Specifically, the first sealing element 30 can be made of materials such as polyurethane, polystyrene, polyvinyl chloride, polyethylene, and polypropylene.

[0087] In some embodiments, the first seal 30 is a one-piece molded structure. This reduces the number of parts in the first seal 30, thus improving its manufacturing efficiency. Specifically, the first seal 30 can be formed using molding methods such as calendering or molding.

[0088] See also Figure 4 In some embodiments, the indoor unit 100 of the air conditioner includes a second seal 80 and a water receiving tray 40 disposed below the heat exchanger 20. The second seal 80 is disposed on the water receiving tray 40. The heat exchanger 20 includes an inclined lower end face 23. The second seal 80 includes a second inclined surface 81 that cooperates with the lower end face 23.

[0089] The heat exchanger 20 can condense water vapor in the air to form condensate. The condensate drips down under the action of gravity. Therefore, the drip tray 40 is used to collect the condensate formed by the heat exchanger 20, reducing the risk of condensate flowing to other places and causing adverse effects.

[0090] In some embodiments, the second seal 80 is a foam component. The first seal 30 and the second seal 80 may be made of the same material or different materials.

[0091] Please see Figure 4 In some embodiments, the indoor unit 100 of the air conditioner includes a second sealing sheet 90 disposed between the lower end face 23 and the second inclined face 81, the second sealing sheet 90 sealing the gap between the second inclined face 81 and the lower end face 23.

[0092] Thus, the second seal 80 can provide support for the heat exchanger 20. At the same time, by sealing the gap between the second seal 80 and the lower end face 23 of the heat exchanger 20 by the second sealing plate 90, the sealing performance between the second seal 80 and the heat exchanger 20 can be improved, thereby improving the heat exchange effect of the heat exchanger 20.

[0093] Specifically, the material of the second sealing sheet 90 can be the same as or different from that of the second sealing element 80. For example, both the second sealing sheet 90 and the second sealing element 80 can be made of foam; or, for example, the second sealing element 80 can be made of plastic and the second sealing sheet 90 can be made of sponge. The second sealing sheet 90 can be integrally molded with the second sealing element 80.

[0094] The heat exchanger 20 and the second sealing plate 90 can be interference-fitted to improve the sealing performance of the heat exchanger 20 and the second sealing plate 90.

[0095] Please see Figure 2 and Figure 4 In some embodiments, the lower end face 23 is higher than the bottom face of the water receiving tray 40.

[0096] This reduces the risk of condensate in the drip tray 40 coming into contact with the lower end face 23 of the heat exchanger 20 and affecting the performance of the heat exchanger 20.

[0097] Specifically, the water receiving tray 40 can be formed by the bottom plate 14 of the housing 10 and the surrounding members 15 disposed around the bottom plate 14, and the bottom surface of the water receiving tray 40 can be the surface of the bottom plate 14. The second sealing member 80 can be disposed on the bottom plate 14, and the heat exchanger 20 can be disposed on the second sealing member 80, so that the heat exchanger 20 as a whole can be located above the bottom plate 14, thereby making the lower end surface 23 of the heat exchanger 20 higher than the bottom surface of the water receiving tray 40.

[0098] Please see Figure 11 The air conditioning system 1000 of this application includes an indoor unit 100 and an outdoor unit 200 as described in any of the above embodiments, and the outdoor unit 200 is connected to the indoor unit 100 via pipes. Specifically, the outdoor unit 200 may include components such as a compressor. During operation, the compressor can perform work on the refrigerant, allowing the refrigerant to exchange heat with the heat exchanger 20, thereby achieving the regulation of the indoor temperature.
