Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to air conditioning indoor units. Background Technology

[0002] An air conditioner, also known as an air conditioning unit, is a device that regulates indoor temperature. An air conditioner typically consists of an outdoor unit located outdoors and an indoor unit located indoors. The indoor unit includes a casing and components such as the evaporator and electrical control box housed within the casing.

[0003] In related technologies, the electrical control box includes a housing, a control board, and wiring terminals. The control board and wiring terminals are arranged horizontally and spaced apart within the housing, causing the control box to occupy a significant amount of space on one side of the evaporator. This passively reduces the size of the evaporator and consequently decreases its energy efficiency. Alternatively, the wiring terminals can be positioned directly above the control board. When after-sales maintenance requires disassembling the control board, it must be removed from the side of the housing. However, when the indoor unit is installed against a wall, there may be walls or other obstacles nearby on the side of the control box, making disassembly difficult and inconvenient for after-sales maintenance. Utility Model Content

[0004] Therefore, it is necessary to provide an indoor air conditioning unit and an air conditioner that addresses the issue of how to increase the effective occupancy of the evaporator in the casing while facilitating the disassembly and assembly of the control board.

[0005] In a first aspect, this application provides an air conditioner indoor unit, comprising:

[0006] The housing has a front panel facing away from the wall.

[0007] Evaporator, the evaporator being disposed within the outer casing;

[0008] An electrical control box is disposed within the housing and located on one side of the evaporator parallel to the front panel; the electrical control box includes:

[0009] A control board, which is electrically connected to the evaporator;

[0010] The box body has a cavity for accommodating the control board, and the box body has an opening on the side facing the front panel for the control board to enter and exit the cavity;

[0011] A lid, detachably connected to the box body and closing the opening; and,

[0012] A wiring terminal is disposed on the cover of the box and is electrically connected to the control board.

[0013] The technical solution will be further explained below:

[0014] In one embodiment, the terminal block is electrically connected to the control board via a connecting wire, and the cover has a first groove communicating with the cavity, through which the connecting wire passes.

[0015] In one embodiment, the cover is provided with a grounding plate, which is connected to the control board via a grounding wire. The cover has a second groove communicating with the cavity, and the grounding wire passes through the second groove.

[0016] In one embodiment, the indoor unit of the air conditioner further includes a connection line for connecting the wiring terminals to the outdoor unit of the air conditioner;

[0017] The cover is provided with a pressure plate for pressing the connection cable against the cover; and / or, the cover is provided with a third cable groove at one end in the width direction of the indoor unit of the air conditioner, and the connection cable passes through the third cable groove.

[0018] In one embodiment, the housing is provided with a first mounting bracket;

[0019] The first mounting bracket is provided with a first mounting base for mounting a display module; and / or,

[0020] The first mounting bracket is provided with a second mounting base for mounting a wireless communication module; and / or,

[0021] The first mounting bracket is provided with a wire clamp for holding the power cord, and the side of the housing facing the first mounting bracket is also provided with a fourth wire groove, which communicates with the cavity and is used to pass the power cord through; and / or,

[0022] The box body is also provided with a fifth cable channel for passing cables through it on the side near the first mounting bracket, and the fifth cable channel is connected to the cavity.

[0023] In one embodiment, the housing is provided with a second mounting bracket, on which an ambient temperature sensor and / or a humidity sensor are mounted, and the ambient temperature sensor and / or humidity sensor are electrically connected to the control board via sensor wires; a sixth wire groove communicating with the cavity is provided on the side of the housing near the second mounting bracket, and the sixth wire groove is used to pass through the sensor wires.

[0024] In one embodiment, the box body includes a first box shell and a second box shell, which together enclose the cavity. One of the first box shell and the second box shell is provided with a first snap-fit ​​portion, and the other is provided with a second snap-fit ​​portion, which engages with the second snap-fit ​​portion.

[0025] In one embodiment, the first outer shell is provided with a first fireproof shell, and the second outer shell is provided with a second fireproof shell.

[0026] In one embodiment, the cover includes a cover body and a fireproof cover. The cover body includes a mounting area for mounting the wiring terminals and a connection area for connecting to the box body. The fireproof cover covers the connection area.

[0027] Secondly, this application also provides an air conditioner, including the aforementioned indoor air conditioner unit.

[0028] In the aforementioned indoor air conditioning unit and air conditioner, by arranging the wiring terminals of the control box on the box cover, and since the box cover faces the front panel of the outer casing, meaning the wiring terminals are located on the side of the control box perpendicular to the front panel, while the evaporator is located on the side of the control box parallel to the front panel, the wiring terminals and evaporator do not interfere with each other spatially. This avoids the wiring terminals occupying space on the side where the evaporator is located, increasing the effective occupancy rate of the evaporator in the outer casing, thereby improving the energy efficiency of the evaporator. Simultaneously, by opening an opening on the side of the control box facing the front panel, the control board can be removed through the opening when after-sales maintenance requires disassembly and reassembly of the control board. Since the opening of the box faces the front panel, and the front panel faces away from the wall when the indoor air conditioning unit is installed against the wall, the opening of the box also faces away from the wall. This avoids obstruction from surrounding walls or obstacles when removing the control board from the opening, thus facilitating the production, assembly, and after-sales maintenance of the control box.

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0045] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0049] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0050] See Figure 1 as well as Figure 2 One embodiment of the air conditioner indoor unit includes a housing 10, an evaporator 30, and an electrical control box 20.

[0051] The housing 10 includes a front panel 11, which is understood to be positioned with its back to the wall when the indoor unit of the air conditioner is installed against the wall.

[0052] Both the evaporator 30 and the electrical control box 20 are housed within the outer casing 10, with the electrical control box 20 located on one side of the evaporator 30 in a direction parallel to the front panel 11. Exemplarily, the electrical control box 20 may be located on one side of the evaporator 30 along the length of the indoor unit of the air conditioner. Figure 2 As shown in the diagram, arrow X points in the length direction of the indoor unit, arrow Z points in the width direction, and arrow Y points in the thickness direction.

[0053] Further, see Figures 3 to 5 The electrical control box 20 includes a control board 23, a box body 21, a cover 22, and wiring terminals 24. The control board 23 is electrically connected to the evaporator 30. The box body 21 has a cavity for accommodating the control board 23, and an opening 210 is provided on the side of the box body 21 facing the front panel 11 for the control board 23 to enter and exit the cavity. The cover 22 is detachably connected to the box body 21 and closes the opening 210. The wiring terminals 24 are disposed on the cover 22 and are electrically connected to the control board 23.

[0054] Specifically, in the aforementioned indoor air conditioning unit, by arranging the wiring terminals 24 of the control box 20 on the cover 22 of the control box 20, and since the cover 22 faces the front panel 11 of the outer casing 10, the wiring terminals 24 are located on the side of the control box 20 perpendicular to the front panel 11 (i.e., in the thickness direction of the indoor air conditioning unit), while the evaporator 30 is located on the side of the control box 20 parallel to the front panel 11. Therefore, the wiring terminals 24 and the evaporator 30 do not interfere with each other spatially, thus avoiding the wiring terminals 24 occupying the space on the side where the evaporator 30 is located, increasing the effective occupancy rate of the evaporator 30 in the outer casing 10, and thus improving the energy efficiency of the evaporator 30. At the same time, by opening an opening 210 on the side of the control box 20's body 21 facing the front panel 11, when after-sales maintenance requires disassembling and installing the control board 23, the control board 23 can be removed from the opening 210 by removing the front panel 11 and the cover 22. Since the opening 210 of the box 21 faces the front panel 11, and the front panel 11 faces away from the wall after the indoor unit of the air conditioner is installed against the wall, the opening 210 of the box 21 also faces away from the wall. This avoids the control board 23 being blocked by the surrounding walls or obstacles when it is taken out or put in through the opening 210, and makes it easier to manufacture, assemble and maintain the electrical control box 20.

[0055] See Figure 7 as well as Figure 8 In one embodiment, the terminal block 24 is electrically connected to the control board 23 via a connecting wire (not shown). The cover 22 has a first wire groove 223 communicating with the cavity, through which the connecting wire passes. By providing the first wire groove 223 on the cover 22, the connecting wire between the terminal block 24 and the control board 23 can be neatly housed within the first wire groove 223, avoiding messy wiring in the control box 20. Furthermore, the first wire groove 223 is arranged adjacent to the terminal block 24, thereby facilitating the connection of the connecting wire between the terminal block 24 and the control board 23.

[0056] See also Figure 7 as well as Figure 8 The cover 22 is provided with a grounding plate 25, which is connected to the control board 23 via a grounding wire (not shown). The cover 22 has a second wire groove 224 communicating with the cavity, and the grounding wire passes through the second wire groove 224. Specifically, the grounding plate 25 is used for grounding to ensure the safety of the electrical control box 20. By placing the grounding plate 25 on the cover 22, the space occupied by the electrical control box 20 on the side where the evaporator 30 is located can be reduced, increasing the effective occupancy rate of the evaporator 30 in the outer casing 10, thereby improving the energy efficiency of the evaporator 30. At the same time, by opening the second wire groove 224 in the cover 22, the grounding wire between the terminal 24 and the control board 23 can be neatly housed in the second wire groove 224, avoiding messy wiring on the electrical control box 20.

[0057] See Figure 7 as well as Figure 8 In one embodiment, the indoor unit of the air conditioner also includes a connection cable (not shown) for connecting the terminal block 24 to the outdoor unit of the air conditioner. The cover 22 is provided with a clamping plate 26 for pressing the connection cable against the cover 22. By clamping the connection cable against the cover 22 with the clamping plate 26, the connection cable can be effectively fixed, thereby ensuring the stability of the connection between the connection cable and the terminal block 24.

[0058] Furthermore, the pressure plate 26 has a first through hole, the cover 22 has a second through hole that aligns with the first through hole, and the box body 21 has a first threaded hole that aligns with the second through hole. The electrical control box 20 also includes a first threaded connector (not shown). The first threaded connector passes through the first through hole and the second through hole and is threadedly engaged with the first threaded hole. In this way, the pressure plate 26, the cover 22 and the box body 21 can be fixed together.

[0059] See Figure 8 In one embodiment, the cover 22 has a third cable tray 225 at one end along the width of the indoor unit, through which the connection cable passes. Specifically, the cover 22 has a protruding portion at one end along the width of the indoor unit, and the third cable tray 225 is formed on the protruding portion and extends through both ends of the protruding portion. By accommodating the connection cable through the third cable tray 225, the wiring on the control box 20 can be made more organized. At the same time, by placing the third cable tray 225 at one end of the cover 22 along the width of the indoor unit, the connection cable can be prevented from occupying the space on the side where the evaporator 30 is located.

[0060] See Figure 4 as well as Figure 5 The housing 21 has a first mounting bracket 215 on one side of the indoor unit of the air conditioner along the width direction. By setting the first mounting bracket 215 on one side of the housing 21 along the width direction of the indoor unit of the air conditioner, the first mounting bracket 215 can be prevented from encroaching on the space on the side where the evaporator 30 is located, thereby ensuring the effective occupancy rate of the evaporator 30 in the housing and improving the energy efficiency of the evaporator 30.

[0061] Furthermore, the first mounting bracket 215 is provided with a first mounting base 2151 for mounting a display module (not shown). The display module can be an LED screen, which is used to display parameters such as the working mode of the indoor unit of the air conditioner, the ambient temperature, and the target temperature.

[0062] See also Figure 4 The first mounting bracket 215 is provided with a second mounting base 2152 for mounting a wireless communication module, wherein the wireless communication module can be a WiFi module or a Bluetooth module.

[0063] See also Figure 4The first mounting bracket 215 is provided with a wire clamp 2153 for securing the power cord 27. Combined with... Figure 5 as well as Figure 6 The side of the housing 21 facing the first mounting bracket 215 is also provided with a fourth wire groove 2172. The fourth wire groove 2172 communicates with the cavity and is used to pass through the power cord 27. The power cord 27 can be fixed to the first mounting bracket 215 by the wire clamp 2153, and the power cord 27 can be passed into the housing 21 and connected to the control board 23 by the fourth wire groove 2172.

[0064] See also Figure 5 as well as Figure 6 The box 21 is also provided with a fifth wire groove 2171 for running wires on the side facing the first mounting bracket 215. The fifth wire groove 2171 is connected to the cavity and is used to run display wires, WiFi wires, stepper motor wires and other wires, so as to avoid messy wiring on the control box.

[0065] In summary, by using the first mounting bracket 215, electrical components such as the display module, wireless communication module, and power cord 27 can be pre-installed on the electrical control box 20, which can significantly improve the assembly efficiency of the air conditioner indoor unit.

[0066] See Figure 5 In one embodiment, the housing 21 is further provided with a second mounting bracket 216, on which an ambient temperature sensor (not shown) and / or a humidity sensor (not shown) are mounted. The ambient temperature sensor is used to acquire the indoor ambient temperature, and the humidity sensor is used to acquire the indoor humidity. The second mounting bracket 216 allows the ambient temperature sensor and / or humidity sensor to be pre-installed on the electrical control box 20, thereby improving the assembly efficiency of the air conditioning indoor unit.

[0067] Further, see Figure 6 The ambient temperature sensor and / or humidity sensor are electrically connected to the control board 23 via sensor wires. A sixth wire groove 2173, communicating with the cavity, is provided on the side of the housing 21 near the second mounting bracket 216. The sixth wire groove 2173 is used to pass the sensor wires. Specifically, the sensor wires can pass through the sixth wire groove 2173 into the cavity and be electrically connected to the control board 23, thereby realizing the electrical connection between the ambient temperature sensor and / or humidity sensor and the control board 23.

[0068] See also Figure 6 In one embodiment, the housing 21 is also provided with a seventh wire groove 2174 that communicates with the cavity. The seventh wire groove 2174 is used to run the fan wire, thereby ensuring that the fan of the indoor unit of the air conditioner is electrically connected to the control board 23.

[0069] See Figure 9 as well as Figure 10The box body 21 includes a first shell 211 and a second shell 212, which together form a cavity. One of the first shell 211 and the second shell 212 has a first snap-fit ​​portion 2111, and the other has a second snap-fit ​​portion 2121. The first snap-fit ​​portion 2111 and the second snap-fit ​​portion 2121 engage with each other. Specifically, the first snap-fit ​​portion 2111 is a slot, and the second snap-fit ​​portion 2121 is a protrusion. By engaging the protrusion in the slot, the first shell 211 and the second shell 212 can be connected and fixed. By configuring the box body 21 with the snap-fit ​​first shell 211 and the second shell 212, the assembly of the box body 21 is facilitated.

[0070] See also Figure 9 as well as Figure 10 The first housing 211 is covered with a first fireproof housing 213, and the second housing 212 is covered with a second fireproof housing 214. This can effectively improve the fire resistance of the electrical control box 20 and enhance its safety.

[0071] For example, in one embodiment, the first housing 211 and the second housing 212 are made of plastic, which facilitates the formation of various wire grooves and mounting brackets on the first housing 211 and the second housing 212 through injection molding, while also providing insulation for the first housing 211 and the second housing 212. The first fireproof housing 213 and the second fireproof housing 214 are made of sheet metal, thereby giving the first fireproof housing 213 and the second fireproof housing 214 good flame-retardant properties.

[0072] See Figure 9 The cover 22 includes a cover body 221 and a fireproof cover 222. The cover body 221 includes a mounting area 2211 for mounting the terminal block 24 and a connection area 2212 for connecting to the box body 21. The fireproof cover 222 covers the connection area 2212. Specifically, the terminal block 24, the ground plate 25, and the wire clamping plate 26 are all disposed in the mounting area 2211. Covering the connection area 2212 with the fireproof cover 222 further improves the fire resistance of the electrical control box 20.

[0073] For example, the cover body 221 is a plastic part, which facilitates the formation of various grooves on the cover body 221 through injection molding, while also enabling the cover body 221 to serve an insulating function. The fireproof cover 222 is a sheet metal part, thereby giving the fireproof cover 222 a good flame-retardant effect.

[0074] Furthermore, the fireproof cover 222 has a third through hole, and the connecting area 2212 of the cover body 221 has a fourth through hole aligned with the third through hole. The box body 21 also has a second threaded hole, and the electrical control box 20 also includes a second threaded connector (not shown). The second threaded connector passes through the third and fourth through holes and is threaded into the second threaded hole, thus securing the fireproof cover 222, the cover body 221, and the box body 21. Understandably, the cover 22 can also be snapped into the box body 21 using a snap-fit ​​or other structure, which is not limited here.

[0075] This application also provides an air conditioner, specifically, the air conditioner includes the indoor unit of any of the above embodiments. Further, the air conditioner may also include an outdoor unit (not shown), which is used to cool or heat the air before sending it into the indoor unit.

[0076] In the aforementioned air conditioner, the indoor unit has its wiring terminals 24 of the control box 20 arranged on its cover 22. Since the cover 22 faces the front panel 11 of the outer casing 10, the wiring terminals 24 are located on the side of the control box 20 along the thickness direction of the indoor unit, while the evaporator 30 is located on the side of the control box 20 along the length direction of the indoor unit. Therefore, the wiring terminals 24 and the evaporator 30 do not interfere with each other spatially, thus avoiding the wiring terminals 24 occupying the space on the side where the evaporator 30 is located. This increases the effective occupancy rate of the evaporator 30 in the outer casing 10, thereby improving the energy efficiency of the evaporator 30. At the same time, by opening an opening 210 on the side of the control box 20's body 21 facing the front panel 11, when after-sales maintenance requires disassembling and installing the control board 23, the control board 23 can be removed from the front panel 11 and the cover 22 through the opening 210. Since the opening 210 of the box 21 faces the front panel 11, and the front panel 11 faces away from the wall after the indoor unit of the air conditioner is installed against the wall, the opening 210 of the box 21 also faces away from the wall. This avoids the control board 23 being blocked by the surrounding walls or obstacles when it is taken out of the opening 210, thus facilitating the production, assembly and after-sales maintenance of the electrical control box 20.

[0077] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0078] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
