Utility Model Content

[0007] In order to have a basic understanding of some aspects of the disclosed embodiments, the following is a simple summary. The summary is not a general review, nor is it intended to determine key / important components or delineate the scope of protection of these embodiments, but as a prelude to the detailed description below.

[0008] The embodiments of the present disclosure provide an indoor unit and an air conditioner to solve the problem that the water receiving tray of the indoor unit is easily broken during transportation in the related art.

[0010] Optionally, there is a gap between the water tray and the air duct assembly.

[0011] Optionally, the water receiving tray includes: a first water receiving section located below the bracket; and a second water receiving section located below the air duct assembly.

[0012] Optionally, the water receiving tray is provided with a connecting rib protruding towards the bracket, and the second connecting part is provided on the connecting rib.

[0013] Optionally, there are multiple second connecting parts, which are arranged sequentially along the circumference of the water receiving tray, and the number of first connecting parts and second connecting parts are equal and correspond one-to-one.

[0014] Optionally, the bracket is located at the rear of the air duct assembly.

[0015] Optionally, the indoor unit also includes: an air inlet grille defining the air inlet and outlet, and a bracket connected to the air inlet grille.

[0044] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0046] Combination Figure 1 and Figure 2 As shown, this embodiment of the present disclosure provides a motor cover 10, including a mounting part 103 and a protective part 101.

[0047] The mounting section 103 is provided with a first connecting structure 1031 for connecting to the motor 20; the protective section 101 is connected to the mounting section 103 and the connection point has an angle, for example... Figure 1 As shown, the protective part and the mounting part are roughly perpendicular, i.e., the angle is 90°. The mounting part 103 and the protective part 101 together define a mounting space for mounting the motor, and the surface of the protective part 101 facing away from the mounting space is provided with a water guiding structure.

[0048] The mounting part 103 is provided with a first connecting structure 1031 and a first connecting and mating structure 202 is provided on the motor. The first connecting structure 1031 and the first connecting and mating structure 202 cooperate to realize the fixed installation of the motor on the mounting part 103.

[0049] The connection between the first connecting structure 1031 and the first connecting mating structure 202 can be a snap-fit ​​or screw connection, which makes the motor easy to disassemble and install and improves disassembly efficiency.

[0050] like Figure 1 As shown, the first connecting structure 1031 and the first connecting mating structure 202 are connected by screws. The first connecting structure 1031 includes a first screw post with a first screw hole. The first connecting mating structure 202 includes a second screw hole, and the first screw hole and the second screw hole are connected by screws.

[0051] Optionally, the motor includes a body 205 and a lug 206. The body 205 is cylindrical and located within the installation space. The lug 206 is located on the radially outer side of the cylinder. A first connecting structure 202 is located on the lug 206, meaning that the first connecting structure 202 is offset from the body 205 to prevent water from entering the body 205 from the connection between the first connecting structure 1031 and the first connecting structure 202.

[0052] The number of first connecting structures 1031 can be multiple, and the number of first connecting mating structures 202 is equal to the number of first connecting structures 1031 and corresponds one-to-one.

[0053] The protective part 101 has a water guiding structure on the surface away from the installation space. Water falling into the protective part 101 will flow away along the water guiding structure, preventing it from flowing into the motor and thus providing waterproof protection for the motor.

[0054] The mounting part 103 is connected to the protective part 101, and the connection point forms an angle, that is, the mounting part 103 and the protective part 101 are not arranged opposite each other. In this way, the mounting part 103 at least partially covers the motor. In addition to being connected to the motor through the first connecting structure 1031, the mounting part 103 can also protect the motor and prevent water, foreign objects, etc. from falling into the installation space, thereby increasing the function of the mounting part 103 and improving the cost performance of the motor cover 10.

[0055] like Figure 1 As shown, the protective part 101 is located on the outer side of the motor in the circumferential direction, and the mounting part 103 is perpendicular to the motor axis and located on the side of the protective part 101 facing the motor.

[0056] The protective part 101 and the mounting part 103 are either an integral structure or separate structures that are connected to each other.

[0057] Optionally, the water guiding structure includes a water guiding groove 102 provided on the surface of the protective part 101 away from the installation space.

[0058] like Figure 1 and Figure 2 As shown, the water guiding structure includes a water guiding channel 102, which is located on the surface of the protective part 101 away from the installation space. The water guiding channel 102 extends along the length of the protective part 101 and is semi-circular with a higher center and lower sides, so that the water in the water guiding channel 102 can be discharged from the higher center of the water guiding channel 102 to both sides, thus preventing water accumulation in the water guiding channel 102.

[0059] The water guide channel 102 includes a first drainage section 1023, a second drainage section 1024, and a middle section 1025. The first drainage section 1023 and the second drainage section 1024 are located at opposite ends along the length of the water guide channel 102. The middle section 1025 connects the first drainage section 1023 and the second drainage section 1024, and the height of the middle section 1025 is greater than the height of the first drainage section 1023 and the second drainage section 1024. Furthermore, the height of the water guide channel 102 gradually decreases from the middle section 1025 to the first drainage section 1023, and also gradually decreases from the middle section 1025 to the second drainage section 1024. In this way, water dripping into the water guide channel 102 flows out along the first drainage section 1023 or the second drainage section 1024. The first drainage section 1023 and the second drainage section 1024 can collect and guide the water flow outwards, preventing water from flowing into the installation space and causing short circuits or motor malfunctions, improving the motor's waterproof performance and safety, and extending the motor's service life.

[0060] Optionally, such as Figure 1 As shown, the protective part 101 has a first water-blocking rib 1021 and a second water-blocking rib 1022 arranged opposite to each other on the surface away from the installation space. The first water-blocking rib 1021 and the second water-blocking rib 1022 together form a water guide groove 102.

[0061] The protective part 101 is provided with a first water-blocking rib 1021 and a second water-blocking rib 1022. The first water-blocking rib 1021 and the second water-blocking rib 1022 are arranged opposite to each other. The first water-blocking rib 1021 and the second water-blocking rib 1022 together enclose the water-guiding groove 102. That is, the first water-blocking rib 1021 and the second water-blocking rib 1022 define the range of the water-blocking groove. By using the first water-blocking rib 1021 and the second water-blocking rib 1022 to define the water-guiding groove 102, the strength of the protective part 101 can be enhanced, and the strength of the protective part 101 can be avoided by the setting of the water-guiding groove 102.

[0062] The first water-blocking rib 1021 and the second water-blocking rib 1022 both extend along the length direction of the protective part 101. The arrangement of the first water-blocking rib 1021 and the second water-blocking rib 1022 can prevent water from overflowing outward along the thickness direction of the first water-blocking rib 1021 and the second water-blocking rib 1022.

[0063] Optionally, such as Figure 2 As shown, the protective part 101 is installed on the outside of the motor and extends along the circumference of the motor.

[0064] The protective section 101 extends circumferentially along the motor, enabling it to provide comprehensive circumferential protection for the motor. This prevents water from flowing into the motor and causing short circuits and motor malfunctions, thereby improving the safety of motor use, extending its service life, and reducing maintenance costs.

[0065] The shape of the protective part 101 is set according to the shape of the motor.

[0066] like Figure 1 and Figure 2 As shown, the protective part 101 extends circumferentially along the main body 205, which is arc-shaped. It can be understood that the protective part 101 can also be a ring set on the outside of the main body 205.

[0067] Optionally, the water-guiding structure extends along the extension direction of the protective part 101.

[0068] The water guiding structure extends along the extension direction of the protective part 101, that is, the water guiding structure extends along the circumference of the motor, so that the water guiding structure can provide comprehensive protection for the circumference of the motor, allowing water to flow away along the outer side of the circumference of the motor, preventing water from flowing into the motor and causing damage, ensuring the normal operation of the motor, and improving the safety of the motor.

[0069] Optionally, such as Figure 1 As shown, the protective part 101 is provided with a second connecting structure 1013 for connecting with the mounting carrier.

[0070] The mounting platform serves as the foundation for the motor. Taking the application of the motor to drive the air conditioner's oscillating blades as an example, the air conditioner includes an indoor unit, which comprises a casing, duct assembly, bracket, indoor heat exchanger, fan, oscillating blades, and motor. The casing has an air inlet and an air outlet. The duct assembly is located inside the casing and includes duct components and an air outlet frame. The bracket and air outlet frame are located on opposite sides of the duct components. The indoor heat exchanger is located on the bracket, between the bracket and the duct components. The fan is located inside the duct components, and the air outlet frame surrounds the air outlet duct. The two ends of the duct are connected to the air inlet and the air outlet, respectively. The fan drives outside air to enter through the air inlet, exchange heat with the indoor heat exchanger, and then flow out through the air outlet. The oscillating blades are located inside the duct or the air outlet, and the motor is connected to the oscillating blade drive to move the blades and achieve air oscillation.

[0071] At this time, the installation carrier is a duct component, such as a ductwork piece.

[0072] The protective part 101 is provided with a second connecting structure 1013, and the mounting carrier is provided with a second connecting and mating structure. The second connecting structure 1013 is connected to the second connecting and mating structure to fix the protective part 101 on the air duct component. The motor is connected to the mounting part 103, and the mounting part 103 is connected to the protective part 101, thereby realizing the connection between the motor and the air duct component.

[0073] The motor can be placed below or above the air duct component. Water flowing from top to bottom into the water guide 102 will flow away along the water guide 102, preventing it from flowing into the motor.

[0074] Taking the motor located below the air duct component as an example, the motor and motor cover 10 are located below the air duct component. The condensate generated on the air duct component drips from top to bottom into the water guide groove 102 and flows away along the water guide groove 102 under its own gravity, which can ensure that the motor can operate stably and improve safety.

[0075] The second connecting structure 1013 is fixedly connected to the second connecting mating structure, for example, by screws or snap-fit ​​connections. There can be multiple second connecting structures 1013, and the number of second connecting mating structures is equal to and corresponds one-to-one with the number of second connecting structures 1013.

[0076] To facilitate the connection between the second connecting structure 1013 and the second connecting mating structure, one of the duct component and the protective part 101 is provided with a positioning hole, and the other is provided with a positioning protrusion 1016. The positioning protrusion 1016 is inserted into the positioning hole to achieve pre-positioning of the duct component and the protective part 101, and then the second connecting structure 1013 is connected to the second connecting mating structure. Figure 1 As shown, the positioning protrusion 1016 is provided on the protective part 101 and is located on the upper surface of the middle part 1025 of the protective part 101.

[0077] Optionally, such as Figure 2 As shown, the protective section 101 includes a first protective section 1011 and a second protective section 1012.

[0078] The first protective section 1011 forms part of the sidewall of the installation space; the second protective section 1012 is located at the end of the first protective section 1011 and outside the installation space; the second connecting structure 1013 is located on the second protective section 1012.

[0079] The protective section 101 includes a first protective section 1011 and a second protective section 1012. The first protective section 1011 is an arc extending circumferentially along the main body 205 and covers the main body 205. In this way, the first protective section 1011 constitutes part of the sidewall of the installation space, which allows the first protective section 1011 to limit the upward movement of the motor and increase the use of the first protective section 1011.

[0080] The first protective section 1011 and the second protective section 1012 are connected, and the connection point forms an angle, which can improve the structural stability and durability of the protective part 101. The second protective section 1012 is located at the end of the first protective section 1011, that is, the second protective section 1012 is offset from the main body 205. The second connecting structure 1013 is located on the second protective section 1012, so that the second connecting structure 1013 is offset from the main body 205. This can prevent water from flowing into the main body 205 through the connection between the second connecting structure 1013 and the second connecting mating structure, thus preventing damage to the motor.

[0081] The first drainage section 1023 is located in the first protection section 1011, and the second drainage section is located in the second protection section 1012.

[0082] Optionally, such as Figure 1 As shown, taking the connection between the protective part 101 and the mounting carrier screw as an example, the second connection structure 1013 includes a screw hole 1014, and a waterproof boss 1015 is provided around the screw hole 1014.

[0083] A screw hole 1014 is provided on the second connecting structure 1013. The screw is connected to the mounting carrier through the screw hole 1014, thereby fixing the second connecting structure 1013 to the mounting carrier. A waterproof boss 1015 is provided around the screw hole 1014. The waterproof boss 1015 is located on the side of the protective part 101 away from the mounting space. The waterproof boss 1015 is annular, extending around the screw hole 1014, located outside the screw hole 1014 and higher than the screw hole 1014. The waterproof boss 1015 increases the height of its position (screw hole 1014), which plays a role in isolating and blocking water. This allows water to flow around the screw hole 1014 along the outer surface of the waterproof boss 1015, thus preventing water from entering the mounting space through the screw hole 1014 and causing a short circuit or malfunction of the motor.

[0084] Optionally, such as Figure 2 As shown, the mounting part 103 is provided with a fixing structure 104 for fixing the motor wire, and the fixing structure 104 is located on the side of the outlet 203 away from the protective part 101, wherein the motor wire is connected to the outlet 203 of the motor.

[0085] The fixing structure 104 includes a limiting part 1041 and a supporting part 1042. The limiting part 1041 and the supporting part 1042 are connected and the connection point is bent, thereby jointly defining a limiting space 1044. The motor wire passes through the limiting space 1044, thereby achieving the positioning of the motor wire. One end of the limiting part 1041 is connected to the mounting part 103, and the other end of the limiting part 1041 is connected to the supporting part 1042. A limiting protrusion 1043 is provided on the end of the supporting part 1042 facing away from the limiting part 1041. The limiting protrusion 1043 is provided on the surface of the supporting part 1042 facing the limiting space 1044. In this way, after the motor wire is placed in the limiting space 1044, the limiting protrusion 1043 can prevent the motor wire from passing through the opening of the limiting space 1044 (where the limiting protrusion is provided).

[0086] The main body 205 is provided with a cable outlet 203. One end of the motor cable is connected to the outlet cable, and the other end is connected to the control board to realize communication between the control board and the motor.

[0087] The fixing structure 104 is located on the side of the outlet 203 away from the protective part 101, so that the fixing structure 104 is lower than the outlet 203 of the motor. After the motor wire extends from the outlet 203, it enters the limiting space 1044 and forms a bend in the limiting space 1044. The bend is lower than the outlet 203. In this way, when water flows from top to bottom on the motor wire to the bend, it cannot continue to flow towards the outlet 203. The water drips off at the bend, which can prevent water from flowing into the outlet 203 along the motor wire and causing a short circuit and damage to the motor, thus improving the safety of the motor.

[0088] According to a second aspect of the present invention, an air conditioner is provided, including an indoor unit, the indoor unit including louvers, a motor and a motor cover 10 as described in any of the above embodiments.

[0089] The motor is connected to the blade drive and is used to drive the blade movement; the motor is located in the installation space.

[0090] The air conditioner provided in this embodiment includes the motor cover 10 as described in any of the above embodiments, and therefore has all the beneficial effects of the motor cover 10 as described in any of the above embodiments, which will not be repeated here.

[0091] like Figures 3 to 8 As shown, the indoor unit also includes an air duct assembly 30, a bracket 40, and a water drip tray 50.

[0092] like Figure 3 and Figure 4 As shown, the air duct assembly 30 defines the air duct; the bracket 40 is provided with a first connecting part 401; the water receiving tray 50 is provided with a second connecting part 503, the first connecting part 401 and the second connecting part 503 are connected to connect the water receiving tray 50 to the bracket 40, and the water receiving tray 50 is not directly connected to the air duct assembly 30.

[0093] like Figure 8 As shown, the air duct assembly 30 includes an air duct component 301 and an air outlet frame 302.

[0094] The water tray 50 is fixed on the bracket 40 by the connection of the first connecting part 401 and the second connecting part 503. The water tray 50 is not directly connected to the air duct assembly 30. The air duct assembly 30 is the main load-bearing component in the indoor unit. Since the water tray 50 is not directly connected to the air duct assembly 30, the impact of the shaking of the air duct assembly 30 on the water tray 50 during transportation is relatively small, and the bracket 40 is subjected to less force. Therefore, connecting the water tray 50 to the bracket 40 can reduce the probability of damage to the water tray 50 during the transportation of the indoor unit.

[0095] The fact that the water tray 50 and the air duct assembly 30 are not directly connected means that the water tray 50 and the air duct assembly 30 are not connected by welding, bonding, snap-fitting or other means, nor are they connected by screws, magnets or other additional connectors.

[0096] Optionally, such as Figure 3 As shown, there is a gap 60 between the water receiving tray 50 and the air duct assembly 30.

[0097] A gap 60 is provided between the water tray 50 and the air duct assembly 30, so that a buffer space is formed between the water tray 50 and the air duct assembly 30. When the air duct assembly 30 is subjected to external force and vibrates during the transportation or unloading of the indoor unit, the existence of the buffer space prevents the water tray 50 from being affected by the vibration of the air duct assembly 30, thus avoiding the impact on the normal operation of the indoor unit due to damage or breakage of the water tray 50.

[0098] Optionally, such as Figure 3 As shown, the water receiving tray 50 includes a first water receiving section 501 and a second water receiving section 502. The first water receiving section 501 is located below the bracket 40; the second water receiving section 502 is located below the air duct assembly 30.

[0099] The first water receiving section 501 is located below the bracket 40 and is used to receive condensate generated on the bracket 40 or components (such as indoor heat exchangers) installed on the bracket 40. The second water receiving section 502 is located below the air duct assembly 30 and is used to receive condensate generated by the air duct assembly 30. The first water receiving section 501 and the second water receiving section 502 are connected, so that only one drain hole can be provided on the water receiving tray 50, that is, the condensate received by the first connecting section and the second connecting section can be discharged outside the machine through a common drain hole.

[0100] Optionally, the first water receiving section 501 and the second water receiving section 502 are on the same plane, which facilitates the timely and rapid discharge of condensate in the first water receiving section 501 and the second water receiving section 502.

[0101] Optionally, such as Figure 5 As shown, the water receiving tray 50 is provided with a first connecting rib 504 protruding toward the bracket 40, and a second connecting part 503 is provided on the first connecting rib 504.

[0102] The water receiving tray 50 is located below the support 40. The upper surface of the water receiving tray 50 is provided with a first connecting rib 504, and a second connecting part 503 is provided on the first connecting rib 504. The first connecting rib 504 not only connects the water receiving tray 50 to the support 40, but also enhances the strength of the water receiving tray 50, improves the load-bearing capacity of the water receiving tray 50, and makes the connection between the water receiving tray 50 and the support 40 more secure.

[0103] The first connecting rib 504 is located below the bracket 40. The first connecting rib 504 extends vertically, and the second connecting part 503 is located at the top of the first connecting rib 504.

[0104] like Figure 6 As shown, the bracket 40 is provided with a second connecting rib 405 protruding toward the water receiving tray 50, and the first connecting part 401 is provided on the second connecting rib 405.

[0105] The bottom wall of the support 40 protrudes downward to form a second connecting rib 405, so as to increase the distance between the support 40 and the water receiving tray 50 and reduce the impact of the swaying of the support 40 on the water receiving tray 50.

[0106] Optionally, there may be multiple second connecting parts 503, which are arranged sequentially along the circumference of the water receiving tray 50. The number of first connecting parts 401 and second connecting parts 503 are equal and correspond one-to-one. For example... Figure 3 As shown, there are two of each of the second connecting parts and the first connecting part.

[0107] Multiple second connecting parts 503 are provided on the water receiving tray 50, which can further enhance the stability of the water receiving tray 50 fixed on the bracket 40, prevent the water receiving tray 50 from being damaged or deformed due to external forces during the transportation of the indoor air conditioning unit, and thus ensure the normal use of the water receiving tray 50.

[0108] The first connecting part 401 and the second connecting part 503 can be connected by various methods such as screw connection, snap-fit ​​or adhesive.

[0109] Optionally, the indoor unit also includes an indoor heat exchanger, which is mounted on the bracket 40 and located between the bracket 40 and the air duct assembly 30.

[0110] Optionally, the bracket 40 is located on the rear side of the air duct assembly 30 to facilitate the installation of the indoor heat exchanger on the bracket 40.

[0111] Optionally, the indoor unit also includes an air inlet grille that defines the air inlet, and the bracket 40 is connected to the air inlet grille.

[0112] In this way, the weight of the indoor heat exchanger is mainly transferred from the bracket 40 to the air inlet grille, which reduces the stress on the bracket 40 and prevents the bracket 40 from shaking during the transportation of the indoor unit, thus preventing damage to the water tray 50.

[0113] Optionally, such as Figure 6 and Figure 7 As shown, the bracket 40 includes a receiving part 402, which is located between the water receiving pan 50 and the indoor heat exchanger. The receiving part 402 defines a water receiving trough 404 corresponding to the indoor heat exchanger. The water receiving trough 404 is provided with a drain outlet 403, which is connected to the water receiving pan 50.

[0114] The receiving part 402 is located below the indoor heat exchanger and not above the first water receiving section 501. In this way, the condensate produced by the indoor heat exchanger first drips into the water receiving tank 404, and then falls into the water receiving pan 50 through the drain outlet 403, avoiding water from falling directly into the water receiving pan 50 and causing water splashing or dripping noise.
