DETAILED DESCRIPTION

[0041] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0042] The indoor unit generally includes a casing, a heat exchanger, a throttle valve, a refrigerant pipe assembly, a water pump assembly and a water receiving pan. The heat exchanger is arranged in the casing. The throttle valve is connected to the heat exchanger through a connecting pipe assembly. The liquid pipe of the refrigerant pipe assembly is connected and communicated with the throttle valve. The air pipe of the refrigerant pipe assembly is connected and communicated with the heat exchanger. The water receiving pan is arranged below the heat exchanger to receive the condensed water flowing down the heat exchanger. The water pump assembly is used to extract the condensed water in the connecting water pan. The throttle valve, the refrigerant pipe assembly and the water pump assembly are all concentrated in one area.

[0043] During the operation of the indoor unit, liquid refrigerant enters the throttle valve, so condensed water is formed on the surface of the throttle valve. The condensed water may flow downward into the indoor environment, thereby affecting the normal use of the indoor unit.

[0044] Therefore, the embodiments of the present application provide an indoor unit and HVAC equipment, which can solve the problem in the above-mentioned related art that condensed water will flow downward into the indoor environment and affect the normal use of the indoor unit.

[0045] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] See also Figures 1 to 3 , Figure 1 A three-dimensional structural diagram of an indoor unit provided in an embodiment of the present application, Figure 2 for Figure 1 Schematic diagram of the three-dimensional structure from another perspective. Figure 3 This is a schematic diagram of the first partial structure of the indoor unit provided in an embodiment of the present application. As shown in the figure, this embodiment provides an indoor unit 100, including a housing 1, an air duct 11 formed in the housing 1, a return air port 111 and an air outlet 112 formed at both ends of the air duct 11, and a wind wheel cavity 113, a pressure diffusion cavity 114 and a heat exchange cavity 115 connected in sequence between the return air port 111 and the air outlet 112, a wind wheel 2 is arranged in the wind wheel cavity 113, and a heat exchanger 3 is arranged in the heat exchange cavity 115.

[0047] During the operation of the indoor unit 100, with the rotation of the wind wheel 2, the air in the indoor environment enters the wind wheel cavity 113 through the return air port 111 and enters the heat exchange cavity 115 after being diffused by the diffusion cavity 114. After the heat exchanger 3 performs heat exchange on the air, the air is discharged from the air outlet 112 to the indoor environment to achieve the corresponding cooling or heating function.

[0048] Generally, since the heat exchanger 3 generates condensed water during operation, a water receiving pan 4 is provided under the heat exchanger 3 to collect the condensed water generated by the heat exchanger 3. By providing the water receiving pan 4, the condensed water generated by the heat exchanger 3 during operation can be collected.

[0049] Please combine Figure 4 , Figure 4 A schematic diagram of the structure of the second partial structure of the indoor unit provided in the embodiment of the present application. It is understandable that, during the operation of the indoor unit 100, if the liquid refrigerant needs to be converted into a gaseous refrigerant, a corresponding pipeline module needs to be provided, and generally, in order to adjust the flow of the liquid refrigerant, the pipeline module includes a throttle valve 5 and a pipe connection assembly 6, and the throttle valve 5 is connected to the heat exchanger 3 through the pipe connection assembly 6. The throttle valve 5 is an electronic expansion valve.

[0050] It can be known from the above that during the use of the indoor unit 100, the throttle valve 5 will generate condensed water, and in order to prevent this part of the condensed water from flowing downward into the indoor environment, in this embodiment, a sealing cover 7 is provided in the housing 1, and the sealing cover 7 is located on one side of the heat exchanger 3, and the sealing cover 7 is located below the throttle valve 5, and can guide the condensed water generated by the throttle valve 5 into the water receiving tray 4. In this way, through the setting of the sealing cover 7, the condensed water generated by the throttle valve 5 can be collected, so as to prevent the condensed water generated by the throttle valve 5 from flowing into the indoor environment to a certain extent, so that the indoor unit 100 provided in this embodiment can maintain long-term normal use, and improve the use performance of the indoor unit 100 provided in this embodiment.

[0051] It should be noted that the sealing cover 7 can not only guide the condensed water generated by the throttle valve 5 into the water receiving tray 4, but also isolate the heat exchanger 3 from the external environment.

[0052] It is not difficult to understand that the condensed water in the water receiving tray 4 needs to be pumped out, so the indoor unit 100 provided in this embodiment should also include a water pump assembly 8, which is arranged at the bottom of the sealing cover 7 and connected to the bottom of the water receiving tray 4. In this way, by providing the water pump assembly 8, the condensed water in the water receiving tray 4 can be pumped out, so that the water receiving tray 4 has a better water receiving performance.

[0053] Please combine Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the third partial structure of the indoor unit provided in the embodiment of the present application. Figure 6 for Figure 5 The enlarged schematic diagram of the local structure at A in the middle. Since the throttle valve 5 is arranged above the sealing cover 7, and the refrigerant pipe assembly 9 needs to connect the heat exchanger 3 with the outdoor unit, a through hole 71 for the refrigerant pipe assembly 9 to pass through needs to be provided on the sealing cover 7, and the shape of the through hole 71 is adapted to the contour shape of the refrigerant pipe assembly 9. In this way, the effective conversion between the liquid refrigerant and the gaseous refrigerant can be achieved. In addition, by making the shape of the through hole 71 adapted to the contour shape of the refrigerant pipe assembly 9, the connection sealing between the sealing cover 7 and the refrigerant pipe assembly 9 is higher, and condensed water is prevented from seeping out from the hole wall of the through hole 71 and the refrigerant pipe assembly 9 to a certain extent.

[0054] Specifically, the refrigerant pipe assembly 9 includes a liquid pipe 91 and an air pipe 92. The liquid pipe 91 is used to transmit liquid refrigerant, and the air pipe 92 is used to transmit gaseous refrigerant. One end of the liquid pipe 91 is connected to the outdoor unit, and the other end of the liquid pipe 91 is connected to the throttle valve 5. One end of the air pipe 92 is connected to the heat exchanger 3, and the other end of the air pipe 92 is connected to the outdoor unit.

[0055] The through hole 71 in this embodiment is a notch, which makes it more convenient to assemble the sealing cover 7 .

[0056] Please combine Figure 7 , Figure 7 A schematic diagram of the three-dimensional structure of the sealing cover in the indoor unit provided in an embodiment of the present application. In order to guide the condensed water on the sealing cover 7 into the water receiving tray 4, in some optional embodiments, a guide groove 72 is formed on the end surface of the sealing cover 7 facing the throttle valve 5, and the guide groove 72 is used to guide the condensed water generated by the throttle valve 5 into the water receiving tray 4.

[0057] In order to allow more condensed water to flow into the water receiving tray 4 and to increase the speed at which the condensed water flows into the water receiving tray 4, in this embodiment, the bottom wall of the guide groove 72 extends downwardly at an angle in the direction close to the water receiving tray 4. In this way, under the action of the gravity of the condensed water, more condensed water received by the sealing cover 7 can flow into the water receiving tray 4 at a faster speed.

[0058] Specifically, in the present embodiment, the guide groove 72 includes a first groove section 721 and a second groove section 722 which are interconnected, and the groove depth of the first groove section 721 is smaller than the groove depth of the second groove section 722, so that a connecting surface 723 is formed at the connection of the first groove section 721 and the second groove section 722, and the connecting surface 723 extends downwardly at an angle in the direction close to the water receiving tray 4, and the groove bottom wall of the second groove section 722 extends downwardly at an angle and is connected to the inside of the water receiving tray 4. In this way, under the guiding effect of the guide groove 72, the condensed water received by the sealing cover 7 can flow more and faster into the water receiving tray 4, and be pumped out through the water pump assembly 8, so as to further prevent the condensed water from flowing downward into the indoor environment.

[0059] It should be noted that the throttle valve 5 may fail during the operation of the indoor unit 100. In this case, the throttle valve 5 needs to be removed for inspection or replacement. In this case, in order to improve the convenience of the throttle valve 5, if the sealing cover 7 is exposed to the environment, it will be more convenient to disassemble the throttle valve 5. Therefore, please refer to Figures 2 to 4 In some optional embodiments, a mounting cavity 12 is formed at the bottom of the housing 1, and the bottom of the mounting cavity 12 is an opening; the sealing cover 7 is exposed through the opening. In this way, when the grille at the return air port 111 is removed, the sealing cover 7 can be observed, and after the water pump assembly 8, the refrigerant pipe assembly 9 and the sealing cover 7 are removed, the throttle valve 5 can be disassembled for inspection.

[0060] Specifically, the installation cavity 12 is located between the wind wheel 2 and the heat exchanger 3, that is, the installation cavity 12 is located below the diffuser cavity 114 and is separated from the diffuser cavity 114 by the housing 1.

[0061] In some embodiments, in order to improve the compactness of the indoor unit 100, other modules or components, such as the electric control module 10, may be disposed in the installation cavity 12. Here, other modules or components disposed in the installation cavity 12 are not specifically limited.

[0062] Furthermore, the indoor unit 100 provided in this embodiment further includes a motor assembly, which includes a motor (not shown in the figure) and a motor bracket 14, the motor is mounted on the motor bracket 14, and the motor is connected to the wind wheel 2 in a transmission manner; the housing 1 includes an outer shell 13, the motor bracket 14 is connected to the outer shell 13; the sealing cover 7 is detachably connected between the motor bracket 14 and the water receiving tray 4. In this way, when the throttle valve 5 is inspected and repaired, it is convenient to remove the sealing cover 7 to improve the inspection and repair efficiency of the throttle valve 5, so that the indoor unit 100 provided in this embodiment can quickly enter a normal working state.

[0063] Please combine Figures 8 to 10 , Figure 8 This is a schematic diagram of the connection structure between the sealing cover, the motor bracket and the water receiving tray in the indoor unit provided in the embodiment of the present application. Fig. 9 for Figure 8 The enlarged schematic diagram of the local structure at B in the middle. Fig.10 for Figure 8 The enlarged schematic diagram of the local structure at C in the middle. Specifically, the water receiving tray 4 includes a main body 41 and an edge 42 connected to each other, the main body 41 is located below the heat exchanger 3, and the edge 42 is located on one side of the heat exchanger 3; the opposite sides of the sealing cover 7 are detachably connected to the edge 42 and the motor bracket 14 respectively. Among them, the main body 41 and the edge 42 are integrally formed, and the edge 42 is located on the side of the main body 41 close to the wind wheel 2, so that the installation position of the sealing cover 7 can be met.

[0064] Generally, the motor bracket 14, the water tray 4 and the sealing cover 7 can all be made of plastic material, and the connection between the plastic materials can be through fasteners or snap-fitting. It is easy to understand that the snap-fitting connection is more convenient during disassembly and does not require the use of third-party tools. Therefore, in this embodiment, the motor bracket 14 and the edge portion 42 are snap-fitted and connected with the sealing cover 7. In this way, the motor bracket 14 and the sealing cover 7 can be quickly assembled and disassembled, and the edge portion 42 and the sealing cover 7 can be quickly assembled and disassembled.

[0065] Please combine Fig.11 , Fig.11A schematic diagram of the three-dimensional structure of the sealing cover in the indoor unit provided in the embodiment of the present application from another perspective. As shown in the figure, in order to achieve the snap-fit ​​connection between the sealing cover 7 and the edge portion 42 and the snap-fit ​​connection between the sealing cover 7 and the motor bracket 14, in some optional embodiments, the sealing cover 7 includes a cover body 73 and a handle portion 74 connected together; the cover body 73 is snap-fitted with the edge portion 42, the through hole 71 and the guide groove 72 are both provided on the cover body 73, the handle portion 74 is snap-fitted with the motor bracket 14, and the free end of the handle portion 74 extends downward. In this way, not only can the snap-fit ​​connection between the sealing cover 7 and the edge portion 42 and the snap-fit ​​connection between the sealing cover 7 and the motor bracket 14 be achieved, but also through the setting of the handle portion 74, when the sealing cover 7 is disassembled, it is convenient to grab the sealing cover 7, so as to further improve the convenience of repairing the throttle valve 5.

[0066] Furthermore, a first clamping portion 20 is provided on one of the cover body 73 and the edge portion 42 , and a clamping slot 30 is provided on the other; the first clamping portion 20 is clamped into the clamping slot 30 and is clamped and connected with the clamping slot 30 to clamp and connect the cover body 73 and the edge portion 42 .

[0067] In a specific implementation of this embodiment, the edge portion 42 protrudes relative to the main body portion 41 toward the side close to the heat exchanger 3, so that the edge portion 42 forms the above-mentioned first clip portion 20. In some other implementations, the first clip portion 20 can also be formed on the edge portion 42. Here, there is no restriction on the formation method of the first clip portion 20; accordingly, the card groove 30 is formed on the cover body 73 of the sealing cover 7, and the groove depth direction of the card groove 30 is consistent with the width direction of the indoor unit 100.

[0068] In order to facilitate the formation of the above-mentioned slot 30, an extension portion 75 may be provided on one side of the cover body 73 close to the water receiving tray 4, and the slot 30 is formed on the extension portion 75 and penetrates the extension portion 75 in the length direction of the indoor unit 100. It can be understood that the size of the extension portion 75 is smaller than that of the cover body 73, and it is easier to open the slot 30 on the extension portion 75 than on the cover body 73.

[0069] It should be noted that the length direction of the indoor unit 100 is Figure 1 , Figure 2 and Figure 5 The xx-axis direction is consistent with the width direction of the indoor unit 100. Figures 1 to 5 The yy-axis direction is consistent.

[0070] In some embodiments, in order to improve the connection reliability between the sealing cover 7 and the water receiving tray 4, the above-mentioned extension portion 75 can be set to be multiple, for example, two, and one extension portion 75 is provided with a card slot 30, and in this embodiment, the edge portion 42 is an integral structure. Of course, in other embodiments, the edge portion 42 can also be set to be multiple, and one edge portion 42 corresponds to one card slot 30. No specific limitation is made here.

[0071] It is easy to understand that when the sealing cover 7 is connected to the water receiving tray 4, if the slot size of the slot 30 is larger than the slot bottom size of the slot 30, then the connection between the slot 30 and the edge portion 42 is easier, that is, when the slot size of the slot 30 is larger, the deformation of the extension portion 75 will be larger, therefore, in the specific implementation of this embodiment, the free end of the lower side wall of the slot 30 extends downwardly. In this way, the opening size of the slot 30 can be increased, which makes it easier to connect the sealing cover 7 to the water receiving tray 4.

[0072] As for the connection between the sealing cover 7 and the motor bracket 14, similarly, a second clamping portion 40 can be provided on one of the handle portion 74 and the motor bracket 14, and a clamping hole 50 can be provided on the other; the second clamping portion 40 is clamped into the clamping hole 50 and connected with the clamping hole 50 to clamp the handle portion 74 and the motor bracket 14.

[0073] Specifically, the second clamping portion 40 is disposed on the motor bracket 14 , the clamping hole 50 is disposed on the handle portion 74 , and the axial direction of the clamping hole 50 is consistent with the width direction of the indoor unit 100 .

[0074] In the present embodiment, the handle portion 74 includes a first lifting means 741 and a second lifting means 742. The first lifting means 741 is connected to the cover body 73 and extends upward, the second lifting means 742 is connected to the first lifting means 7414 and extends downward, and the clamping hole 50 is provided on the second lifting means 742. In order to facilitate the molding of the handle portion 74, the connection between the first lifting means 741 and the second lifting means 742 and the bottom of the second lifting means 742 are both curved structures.

[0075] It should be noted that due to the structural arrangement of the handle portion 74, the strength of the handle portion 74 is relatively weak at the connection between the first lifting means 741 and the second lifting means 742 and at the bottom of the second lifting means 742. Therefore, in order to improve the structural strength of the handle portion 74 and to improve the connection reliability between the sealing cover 7 and the motor bracket 14, a reinforcing rib 76 may be provided on the handle portion 74, and the reinforcing rib 76 may be provided at the connection between the first lifting means 741 and the second lifting means 742 and / or at the bottom of the second lifting means 742.

[0076] When the sealing cover 7 is connected to the motor bracket 14, if the deformation of either the motor bracket 14 or the sealing cover 7 can be increased, the assembly efficiency between the sealing cover 7 and the motor bracket 14 can be improved. Fig.10 In some optional embodiments, a cavity 401 may be provided on the second clamping portion 40, and the depth direction of the cavity 401 may be consistent with the axial direction of the clamping hole 50. In this way, the deformation amount of the second clamping portion 40 can be increased, and the assembly efficiency between the sealing cover 7 and the motor bracket 14 can be improved.

[0077] It is understandable that when the sealing cover 7 and the motor bracket 14 are assembled, if the relative position between the sealing cover 7 and the motor bracket 14 can be determined, the assembly efficiency of the sealing cover 7 and the motor bracket 14 can be further improved. Therefore, in some optional embodiments, a limiting structure 60 can be provided between the sealing cover 7 and the motor bracket 14, and the limiting structure 60 is used to limit the relative position between the sealing cover 7 and the motor bracket 14 in the length direction of the indoor unit 100 and the width direction of the indoor unit 100. In this way, through the setting of the limiting structure 60, when the sealing cover 7 and the motor bracket 14 are assembled, the sealing cover 7 and the motor bracket 14 can be clamped after the relative position between the sealing cover 7 and the motor bracket 14 is determined, so as to further improve the assembly efficiency between the sealing cover 7 and the motor bracket 14.

[0078] Specifically, Fig.10 As shown, the limiting structure 60 includes a limiting protrusion 601, which is arranged on one of the sealing cover 7 and the motor bracket 14; and a limiting hole 602 for inserting the limiting protrusion 601 is provided on the other of the sealing cover 7 and the motor bracket 14.

[0079] Specifically, the limiting protrusion 601 is provided on the motor bracket 14, and the free end of the limiting protrusion 601 extends downward, and the limiting hole 602 is provided on the cover body 73 and penetrates the cover body 73. Since the structural strength of the place where the limiting hole 602 is provided is relatively low, in some embodiments, the thickness of the cover body 73 where the limiting hole 602 is provided is greater than the thickness of other places of the cover body 73. In this way, it is possible to avoid to some extent the reduction of the structural strength of the cover body 73 due to the provision of the limiting hole 602, and thus, the service life of the sealing cover 7 can be extended.

[0080] It can be known from the above that when the throttle valve 5 fails, the sealing cover 7 needs to be removed to inspect the throttle valve 5. Then, after the sealing cover 7 is removed, the throttle valve 5 can be completely exposed, and the inspection efficiency of the throttle valve 5 can be further improved. Based on this, as an optional implementation, the projection of the throttle valve 5 on the horizontal plane can fall within the projection area of ​​the sealing cover 7 on the horizontal plane.
