Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an air conditioner. Background Technology

[0002] With the improvement of living standards, air conditioners have become a major household appliance in people's daily lives. Air conditioners can circulate and exchange heat in indoor air, thereby providing people with a comfortable living environment.

[0003] Generally, an air conditioner has an air outlet cavity and a mounting cavity. The air outlet cavity houses the fan blade assembly, while the mounting cavity houses electrical components such as a drive motor. The drive motor drives the fan blade assembly to oscillate and expel air. The air outlet cavity and the mounting cavity are separated by a partition, and a through hole is provided in the partition so that the fan blade assembly can be connected to the drive motor through the through hole.

[0004] However, gaps exist between the fan blade assembly and the through-hole, allowing cold air from the outlet cavity to easily pass through and enter the mounting cavity. The cold air interacts with the room-temperature air in the mounting cavity, creating condensation. This condensation makes the mounting cavity damp, potentially damaging the drive motor and affecting the air conditioner's lifespan. Utility Model Content

[0005] The main purpose of this utility model is to propose an air conditioner that aims to improve the service life of the air conditioner.

[0006] To achieve the above objectives, the air conditioner proposed in this utility model includes:

[0007] The housing has an air outlet cavity and a mounting cavity formed inside it. A partition is provided between the air outlet cavity and the mounting cavity. The partition has a clearance hole, and the air outlet cavity and the mounting cavity are connected through the clearance hole. An air outlet and a dummy air outlet are formed inside the air outlet cavity. The air outlet and the dummy air outlet are arranged sequentially in the direction close to the partition.

[0008] A louver assembly, the louver assembly being installed at the air outlet; and

[0009] The motor assembly is installed in the mounting cavity and is positioned opposite the dummy air vent. The louver assembly is connected to the motor assembly via the clearance hole.

[0010] In one embodiment, the partition is provided with a positioning structure and a fixing structure, and the motor assembly is mounted on the partition through the positioning structure and the fixing structure.

[0011] In one embodiment, the motor assembly includes a mounting base and a motor body mounted on the mounting base, the positioning structure being configured as a positioning groove into which the mounting base engages.

[0012] In one embodiment, the positioning groove is provided with two opposing positioning ribs, and along the axial direction of the motor assembly, the opposite sides of the fixing seat respectively abut against the two positioning ribs.

[0013] In one embodiment, the fixing structure is configured as a screw-locking structure, and the motor assembly is fixed to the partition by the screw-locking structure.

[0014] In one embodiment, the screw fastening structure includes a first connecting hole in the fixing base, a second connecting hole in the partition, and a connector. The extension direction of the first connecting hole is perpendicular to the axial direction of the motor assembly, and the connector passes through the first connecting hole and the second connecting hole in sequence.

[0015] In one embodiment, a connecting rib is provided between the positioning groove and the second connecting hole.

[0016] In one embodiment, the louver assembly includes a connecting rod and a plurality of blades spaced apart on the connecting rod, the connecting rod passing through the clearance hole and being drively connected to the output shaft of the motor assembly.

[0017] In one embodiment, the connecting rod includes a main rod portion for mounting the blade and a secondary rod portion for connecting to the motor assembly, wherein the distance difference between the axis of the main rod portion and the axis of the secondary rod portion is less than a preset distance.

[0018] In one embodiment, the preset distance is 3mm.

[0019] In one embodiment, the main rod and the secondary rod are an integral structure.

[0020] This invention provides a casing and a louver assembly and a motor assembly within the air conditioner. The casing contains an air outlet chamber and a mounting chamber separated by a partition. These two chambers are connected by clearance holes in the partition. The air outlet chamber contains an air outlet and a dummy air outlet, with the dummy air outlet positioned close to the partition. The louver assembly is mounted at the air outlet, and the motor assembly is mounted in the mounting chamber, opposite the dummy air outlet. The louver assembly is connected to the motor assembly via the clearance holes. Compared to mounting the motor assembly near the air outlet, this invention mounts it near the dummy air outlet. Firstly, because the airflow at the dummy air outlet is smaller and the temperature fluctuations are less pronounced, condensation is less likely to occur on the motor assembly, preventing moisture damage and extending its lifespan. This improves the overall lifespan of the air conditioner and reduces operating costs. Secondly, it eliminates the need for additional sealing of the motor assembly, further reducing costs and contributing to a lighter air conditioner. Attached Figure Description

[0036] With the improvement of living standards, air conditioners have become a major household appliance in people's daily lives. Air conditioners can circulate and exchange heat in indoor air, thereby providing people with a comfortable living environment.

[0037] Generally, an air conditioner has an air outlet cavity and a mounting cavity. The air outlet cavity houses the fan blade assembly, while the mounting cavity houses electrical components such as a drive motor. The drive motor drives the fan blade assembly to oscillate and expel air. The air outlet cavity and the mounting cavity are separated by a partition, and a through hole is provided in the partition so that the fan blade assembly can be connected to the drive motor through the through hole.

[0038] However, gaps exist between the fan blade assembly and the through-hole, allowing cold air from the outlet cavity to easily pass through and enter the mounting cavity. The cold air interacts with the room-temperature air in the mounting cavity, creating condensation. This condensation makes the mounting cavity damp, potentially damaging the drive motor and affecting the air conditioner's lifespan.

[0039] This utility model proposes an air conditioner.

[0040] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the air conditioner includes a housing 100, a louver assembly 200, and a motor assembly 300. The housing 100 has an air outlet cavity 110 and a mounting cavity 120. A partition 130 is provided between the air outlet cavity 110 and the mounting cavity 120, and a clearance hole 131 is provided on the partition 130. The air outlet cavity 110 and the mounting cavity 120 are connected through the clearance hole 131. An air outlet 111 and a dummy air outlet 112 are formed within the air outlet cavity 110. The air outlet 111 and the dummy air outlet 112 are arranged sequentially in the direction near the partition 130. The louver assembly 200 is installed at the air outlet 111. The motor assembly 300 is installed in the mounting cavity 120 and is positioned opposite to the dummy air outlet 112. The louver assembly 200 is connected to the motor assembly 300 via the clearance hole 131.

[0041] Specifically, the housing 100 contains an air outlet cavity 110 and a mounting cavity 120 separated by a partition 130. The air outlet cavity 110 has an air outlet 111 and a dummy air outlet 112, with the dummy air outlet 112 positioned close to the partition 130, thus placing the mounting cavity 120 close to the dummy air outlet 112. A louver assembly 200 is installed in the air outlet cavity 110, corresponding to the air outlet 111. A motor assembly 300 is installed in the mounting cavity 120. The motor assembly 300 and the louver assembly 200 are connected via a clearance hole 131 on the partition 130, allowing the motor assembly 300 to drive the louver assembly 200 to oscillate and generate airflow. Understandably, the airflow at the air outlet 111 is larger, and the structure near the air outlet 111 is more susceptible to condensation due to alternating temperature changes. Conversely, the airflow at the dummy air outlet 112 is smaller, and the alternating temperature changes are weaker, making condensation less likely to occur. In this way, by placing the mounting cavity 120 close to the dummy air vent 112, condensation on the motor assembly 300 is avoided, thereby preventing moisture damage to the motor assembly 300.

[0042] The technical solution of this utility model involves setting a housing 100 and a louver assembly 200 and a motor assembly 300 inside the housing 100 in an air conditioner. The housing 100 has an air outlet cavity 110 and an installation cavity 120 separated by a partition 130. The air outlet cavity 110 and the installation cavity 120 are connected by a clearance hole 131 on the partition 130. An air outlet 111 and a dummy air outlet 112 are formed in the air outlet cavity 110. The dummy air outlet 112 is set close to the partition 130. The louver assembly 200 is installed in the air outlet 111. The motor assembly 300 is installed in the installation cavity 120 and is set opposite to the dummy air outlet 112. The louver assembly 200 is connected to the motor assembly 300 through the clearance hole 131. Therefore, compared to installing the motor assembly 300 near the air outlet 111, this invention installs the motor assembly 300 near the dummy air outlet 112. Firstly, because the airflow at the dummy air outlet 112 is smaller and the temperature fluctuation is weaker, condensation is less likely to occur on the motor assembly 300, thus preventing moisture damage and extending its service life. This, in turn, extends the lifespan of the air conditioner and reduces operating costs. Secondly, it eliminates the need for additional sealing for the motor assembly 300, further reducing the cost of the air conditioner and contributing to its lightweight design.

[0043] Please see Figure 3 and Figure 4 In an embodiment of this utility model, the partition 130 is provided with a positioning structure 400 and a fixing structure 500, and the motor assembly 300 is installed on the partition 130 through the positioning structure 400 and the fixing structure 500.

[0044] Understandably, the partition 130 has a positioning structure 400 and a fixing structure 500 on the side facing the mounting cavity 120. The positioning structure 400 provides guidance for the installation of the motor assembly 300, which is beneficial to the accuracy and speed of the installation. The fixing structure 500 improves the installation stability and reliability of the motor assembly 300. The cooperation between the positioning structure 400 and the fixing structure 500 ensures both the installation efficiency and installation stability of the motor assembly 300.

[0045] Please see Figure 3 and Figure 4 In an embodiment of this utility model, the motor assembly 300 includes a fixed base 310 and a motor body 320 mounted on the fixed base 310. The positioning structure 400 is configured as a positioning groove 410, and the fixed base 310 is engaged in the positioning groove 410.

[0046] In the embodiment shown in the figures of this utility model, the positioning structure 400 is configured as a positioning groove 410. When installing the motor assembly 300, the fixing seat 310 of the motor assembly 300 is first inserted into the positioning groove 410, and then the fixing structure 500 fixes the motor assembly 300 to the partition 130. The positioning groove 410 provides positioning guidance for the installation of the motor assembly 300. Of course, in other embodiments, the positioning structure 400 can also be a matching positioning bolt and positioning hole, with one of the fixing seat 310 and the partition 130 having a positioning bolt and the other having a positioning hole.

[0047] Please see Figure 4 In an embodiment of this utility model, the positioning groove 410 is provided with two opposing positioning ribs 411, and along the axial direction of the motor assembly 300, the opposite sides of the fixing seat 310 respectively abut against the two positioning ribs 411.

[0048] Specifically, for ease of explanation, the axial direction of the motor assembly 300 is defined as the vertical direction. Along the vertical direction, the positioning groove 410 includes two opposing positioning ribs 411, and the fixing seat 310 includes two opposing sides. After the fixing seat 310 is engaged with the positioning groove 410, the opposing sides of the fixing seat 310 abut against the two positioning members, thereby limiting the vertical movement of the motor assembly 300 and preventing displacement of the motor assembly 300 in the vertical direction. In one embodiment, a reinforcing rib 412 is also connected between the two positioning ribs 411, thus connecting the two positioning ribs 411 to enhance their structural strength and ensure the reliable positioning of the motor assembly 300 by the positioning groove 410.

[0049] Please see Figure 4 In this embodiment of the invention, the fixing structure 500 is configured as a screw-locking structure, and the motor assembly 300 is fixed to the partition 130 by the screw-locking structure. Thus, the use of the screw-locking structure reduces the installation difficulty of the motor assembly 300, making its installation simple. Of course, in other embodiments, the fixing structure 500 can also be a snap-fit, riveting, or other connection structure.

[0050] Please see Figure 4 In an embodiment of this utility model, the screw fastening structure includes a first connecting hole (not shown) provided in the fixing base 310, a second connecting hole 511 provided in the partition 130, and a connector (not shown). The extension direction of the first connecting hole is perpendicular to the axial direction of the motor assembly 300, and the connector passes through the first connecting hole and the second connecting hole 511 in sequence.

[0051] Understandably, in this utility model, the air conditioner can be configured as a wall-mounted unit, a floor-standing unit, or other structural forms. Taking a wall-mounted unit as an example, the air conditioner has a certain length, width, and thickness. The motor assembly 300 is installed at one end along the length of the air conditioner, and the axial direction of the motor assembly 300 is also the width direction of the air conditioner. The two opposing positioning ribs 411 of the positioning groove 410 mentioned above are arranged along the width direction of the air conditioner. The extending direction of the first connecting hole and the second connecting hole 511 is consistent with the length direction of the air conditioner. The connecting piece passes through the first connecting hole and the second connecting hole 511, thereby fixing the fixing base 310 to the partition 130. In one embodiment, the connecting piece is configured as a screw, bolt, etc. In this way, while fixing the motor assembly 300, positioning of the motor assembly 300 in multiple directions is also achieved, avoiding displacement and rotation of the motor assembly 300 relative to the partition 130. Thus, in this utility model, the motor assembly 300 can be installed using only one screw and the positioning slot 410, achieving rapid assembly of the motor assembly 300 and improving assembly efficiency.

[0052] Please see Figure 4 In this embodiment of the invention, a connecting rib 512 is provided between the positioning groove 410 and the second connecting hole 511. The provision of the connecting rib 512 improves the structural strength of the positioning groove 410 and the second connecting hole 511, which is beneficial to the positioning and secure fixing of the motor assembly 300. In one embodiment, along the thickness direction of the air conditioner, the projections of the positioning groove 410 and the second connecting hole 511 do not coincide at least partially, thus further avoiding relative displacement between the motor assembly 300 and the partition 130.

[0053] Please see Figure 1 and Figure 2 In an embodiment of this utility model, the louver assembly 200 includes a connecting rod 210 and a plurality of blades 220 spaced apart on the connecting rod 210. The connecting rod 210 passes through the clearance hole 131 and is connected to the output shaft of the motor assembly 300 for transmission.

[0054] Specifically, the motor assembly 300 drives the connecting rod 210 to move, and the connecting rod 210 causes the blades 220 to swing, thereby generating airflow. In this invention, the louver assembly 200 is directly connected to the motor assembly 300 via the connecting rod 210, saving the need for a crankshaft, which helps reduce the operating noise of the air conditioner and improves transmission efficiency.

[0055] Please see Figure 2 and Figure 3 In an embodiment of this utility model, the connecting rod 210 includes a main rod portion 211 for mounting the blade 220 and a secondary rod portion 212 for connecting to the motor assembly 300. The distance difference between the axis of the main rod portion 211 and the axis of the secondary rod portion 212 is less than a preset distance.

[0056] Understandably, a baffle 113 is provided within the receiving cavity, positioned close to the partition 130. A false air vent 112 is formed at the baffle 113 within the receiving cavity, effectively preventing the airflow from the air conditioner from blowing directly onto the partition 130. A louver assembly 200 is installed at the air outlet 111, and a connecting rod 210 extends within the receiving cavity and protrudes from the clearance hole 131. Considering the structure of the baffle 113, a bending structure can be formed between the main rod portion 211 and the secondary rod portion 212 of the connecting rod 210. In one embodiment, the distance difference between the axis of the main rod portion 211 and the axis of the secondary rod portion 212 is less than a preset distance. More specifically, in one embodiment, the preset distance is 3mm. This makes the overall structure of the connecting rod 210 roughly "I"-shaped. Compared to a "Z"-shaped structure, the "I"-shaped connecting rod 210 has better strength and does not affect the left-right oscillation of the air conditioner.

[0057] In this utility model, the distance difference between the axis of the main rod 211 and the axis of the auxiliary rod 212 is set to be less than a preset distance. This ensures that the connecting rod 210 is roughly in the shape of an "I" to ensure the structural strength of the connecting rod 210. At the same time, it also ensures that the baffle 113 blocks the air outlet of the air conditioner to prevent condensation at the false air outlet 112.

[0058] Please see Figure 2 and Figure 3 In this embodiment of the invention, the main rod 211 and the auxiliary rod 212 are an integral structure. Therefore, compared to the separate arrangement of the main rod 211 and the auxiliary rod 212, the integral arrangement of the main rod 211 and the auxiliary rod 212 is beneficial to improving the overall structural strength of the connecting rod 210 and improving the assembly efficiency of the air conditioner.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
