Description

Technical Field

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

[0002] Currently, with the continuous improvement of living standards, people's requirements for air conditioners are also increasing. In order to improve the cleanliness of the air vents from the air conditioner, a sterilization module is usually installed on the evaporator. However, the current sterilization modules are generally installed on the evaporator by a mounting bracket, which involves a large number of parts, a complicated installation process, and low installation efficiency. Furthermore, the limiting structure of the circuit board inside the sterilization module is complicated, making it inconvenient to disassemble and maintain. Utility Model Content

[0003] The problem solved by this invention is how to reduce the number of installation parts of the sterilization module, simplify the installation process, improve installation efficiency, and optimize the limiting structure of the circuit board to facilitate disassembly and maintenance while ensuring the limiting effect.

[0004] To solve the above problems, the technical solution of this utility model is implemented as follows:

[0005] Firstly, this utility model provides a sterilization module, including a housing, a circuit board and a sterilization unit disposed within the housing, the sterilization unit being connected to the circuit board. The housing is provided with limiting posts and clips, the circuit board has through holes, the limiting posts cooperating with the through holes, and the clips engaging with the circuit board. Compared with the prior art, the sterilization module provided by this utility model, due to the use of a housing connected to the evaporator and limiting posts and clips cooperating with the circuit board, can reduce the number of installation parts of the sterilization module, simplify the installation process, improve installation efficiency, and optimize the limiting structure of the circuit board, facilitating disassembly and maintenance while ensuring the limiting effect.

[0006] Furthermore, the housing includes a base and a top cover, which are detachably connected. Limiting posts and latches are located on the base, and the top cover is located on the side of the base furthest from the evaporator. This facilitates installation and removal.

[0007] Furthermore, the base is equipped with a limiting ring and a clearance hole. The limiting ring communicates with the clearance hole, the circuit board abuts against the limiting ring, and the sterilization unit extends into and cooperates with the limiting ring. The limiting ring can limit the sterilization unit to prevent it from moving relative to the outer casing. The sterilization unit can emit ultraviolet light through the clearance hole to sterilize the airflow with ultraviolet light.

[0008] Furthermore, the top cover is provided with a retaining ring, the position of which corresponds to the position of the limiting ring. The retaining ring is used to press the circuit board onto the limiting ring.

[0009] Furthermore, the base has multiple heat dissipation holes spaced apart. These holes work together to further improve the heat dissipation of the circuit board, ensuring stable, safe, and reliable operation.

[0010] Furthermore, the top cover has multiple clearance notches on the side near the base, and these clearance notches are spaced apart to facilitate the separation of the top cover from the base.

[0011] Furthermore, the top cover extends to provide a lever, which is used to facilitate the application of force.

[0012] Furthermore, the base is equipped with multiple locking platforms, which are spaced apart and arranged sequentially along the edge of the base. The top cover has multiple locking slots, each of which engages with one locking platform. The multiple slots and platforms work together to improve the locking effect, prevent the top cover from accidentally detaching from the base, and ensure stability and reliability.

[0013] Furthermore, the outer casing extends along a first direction and is provided with a connecting platform. The connecting platform has mounting holes and is used to connect with the bracket screws of the evaporator. The outer casing extends along a second direction and is provided with clamps, which are used to engage with the copper tubes of the evaporator. The first direction is perpendicular to the second direction. The connecting platform and the clamps work together to firmly fix the outer casing to the evaporator from two directions, preventing the outer casing from moving relative to the evaporator, ensuring the reliability of the connection between the sterilization module and the evaporator, and facilitating disassembly and maintenance with high installation efficiency.

[0014] Secondly, this utility model provides an air conditioner including the aforementioned sterilization module. The sterilization module includes a housing, a circuit board, and a sterilization unit disposed within the housing. The sterilization unit is connected to the circuit board. The housing is provided with limiting posts and clips. The circuit board has through holes, the limiting posts cooperate with the through holes, and the clips engage with the circuit board.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] First Embodiment

[0026] Please refer to the reference. Figures 1 to 7 This utility model provides a sterilization module 100 for ultraviolet sterilization. It reduces the number of mounting parts in the sterilization module 100, simplifies the installation process, improves installation efficiency, and optimizes the limiting structure of the circuit board 120, facilitating disassembly and maintenance while ensuring the limiting effect.

[0027] It should be noted that the sterilization module 100 is applied to a wall-mounted air conditioner, which is mounted on an indoor wall and blows hot or cold air into the room to achieve heating or cooling functions. Specifically, the wall-mounted air conditioner includes a sterilization module 100, a fan (not shown in the figure), and an evaporator 200; the fan is used to generate negative pressure to drive airflow and form an outlet airflow; the evaporator 200 is used to exchange heat with the outlet airflow to achieve the heating or cooling function of the outlet airflow to meet user needs; the sterilization module 100 is installed on the evaporator 200 and is used to perform ultraviolet sterilization on the outlet airflow to improve the cleanliness of the outlet airflow, thereby improving the user experience.

[0028] The sterilization module 100 includes a housing 110, a circuit board 120, and a sterilization unit 130. Both the circuit board 120 and the sterilization unit 130 are housed within the housing 110. The sterilization unit 130 is connected to the circuit board 120, which provides power and control to the sterilization unit 130, enabling it to emit ultraviolet light for ultraviolet sterilization of the exhaust airflow. Specifically, the housing 110 has a limiting post 111 and a latch 112, and the circuit board 120 has a through hole 121. The limiting post 111 engages with the through hole 121, allowing the housing 110 to limit the circuit board 120's position and prevent it from wobbling within the housing 110. The latch 112 engages with the circuit board 120 to fix its relative position to the housing 110, preventing movement of the circuit board 120 relative to the housing 110. In this way, the limiting post 111 and the buckle 112 work together to effectively limit the circuit board 120, thereby optimizing the limiting structure and facilitating the disassembly, assembly, and maintenance of the circuit board 120 while ensuring the limiting effect.

[0029] Furthermore, the housing 110 is used to connect to the evaporator 200. By directly connecting the housing 110 to the evaporator 200, the mounting bracket in the prior art is eliminated, which effectively reduces the number of mounting parts of the sterilization module 100, simplifies the installation process, and improves installation efficiency.

[0030] It should be noted that during the installation of circuit board 120, the through hole 121 of circuit board 120 is first aligned with the limiting post 111; then, circuit board 120 is pressed down along the extension direction of limiting post 111 so that limiting post 111 passes through through hole 121. During this process, the latch 112 undergoes elastic deformation under the pressing pressure to make room for circuit board 120; when circuit board 120 is installed in place, latch 112 rebounds under its own elastic force to snap circuit board 120 into housing 110, thereby fixing the relative position of circuit board 120 and housing 110.

[0031] Preferably, the circuit board 120 is elongated, with limiting posts 111 and latches 112 positioned opposite each other at both ends of the circuit board 120 along its length. After the circuit board 120 is installed, the limiting posts 111 limit the position of one end of the circuit board 120, and the latches 112 limit the position of the other end of the circuit board 120, ensuring that neither end of the circuit board 120 moves relative to the housing along its length, thereby improving the limiting effect.

[0032] In this embodiment, there are two limiting posts 111, two latches 112, and two through holes 121. Each limiting post 111 engages with one through hole 121. Each limiting post 111 and one latch 112 are positioned opposite each other at both ends of the circuit board 120 along its length, and opposite each other at both ends of the circuit board 120 along its width. That is, the two limiting posts 111 and the two latches 112 are respectively located at the four corners of the circuit board 120, with the two limiting posts 111 and the two latches 112 diagonally opposite each other. In this way, the two limiting posts 111 and the two latches 112 work together to limit the movement at the four corners of the circuit board 120, further improving the limiting effect. Furthermore, installation can be completed even if the circuit board 120 is rotated 180 degrees, providing good error-proofing. However, this is not the only option. In other embodiments, the number of limiting posts 111, buckles 112, and through holes 121 can be one or four. There is no specific limitation on the number of limiting posts 111, buckles 112, and through holes 121.

[0033] Preferably, the limiting post 111 includes a support portion 1111 and a post portion 1112 connected to each other, with the cross-sectional area of ​​the support portion 1111 being larger than that of the post portion 1112. In this embodiment, the support portion 1111 and the post portion 1112 are integrally formed to improve the connection strength. Specifically, the post portion 1112 mates with the through hole 121, and the outer shell 110 can limit the circuit board 120 through the mate of the post portion 1112 and the through hole 121; the support portion 1111 abuts against the circuit board 120, and the support portion 1111 can support the circuit board 120 to limit the installation position of the circuit board 120, with good support effect.

[0034] The housing 110 includes a base 118 and a top cover 119. The base 118 and the top cover 119 are detachably connected. A limiting post 111 and a buckle 112 are both provided on the base 118. The top cover 119 is located on the side of the base 118 away from the evaporator 200 to facilitate installation and removal.

[0035] It should be noted that since the circuit board 120 generates heat during operation, heat dissipation holes 113 are provided on the outer casing 110 to achieve heat dissipation and ensure the stability of the circuit board 120's operation. In this embodiment, the base 118 has multiple heat dissipation holes 113, which are spaced apart and work together to further improve the heat dissipation effect of the circuit board 120, ensuring stable and reliable operation. Furthermore, since the base 118 is closer to the evaporator 200 than the top cover 119, placing the heat dissipation holes 113 on the base 118 ensures that ultraviolet rays leaking through the holes 113 are directed towards the evaporator 200. The evaporator 200 can then block the leaked ultraviolet rays to prevent severe light leakage from damaging other plastic components inside the air conditioner.

[0036] Preferably, the outer casing 110 extends along a first direction and is provided with a connecting platform 114. The connecting platform 114 has a mounting hole 1141 for screws to pass through, and the connecting platform 114 is used to connect with the bracket 210 of the evaporator 200 by screws. The outer casing 110 extends along a second direction and is provided with a clamping claw 115, which is used to engage with the copper tube 220 of the evaporator 200. The first direction is perpendicular to the second direction. Specifically, the connecting platform 114 and the clamping claw 115 are both provided on the base 118. The connecting platform 114 and the clamping claw 115 work together to firmly fix the outer casing 110 to the evaporator 200 from two directions, preventing the outer casing 110 from moving relative to the evaporator 200, ensuring the reliability of the connection between the sterilization module 100 and the evaporator 200, and facilitating disassembly and maintenance with high installation efficiency.

[0037] In this embodiment, there are two claws 115. The two claws 115 are arranged opposite each other at both ends of the outer shell 110 along its length direction. The two claws 115 work together to improve the reliability of the engagement, further fix the relative position of the outer shell 110 and the evaporator 200, and improve the positioning effect.

[0038] Preferably, the base 118 is provided with a limiting ring 116 and a clearance hole 117. The limiting ring 116 communicates with the clearance hole 117. The circuit board 120 abuts against the limiting ring 116. The sterilization unit 130 extends into the limiting ring 116 and cooperates with it. Specifically, the limiting ring 116 can limit the sterilization unit 130 to prevent it from moving relative to the base 118. The sterilization unit 130 can emit ultraviolet light through the clearance hole 117 to sterilize the airflow with ultraviolet light.

[0039] Furthermore, the top cover 119 is provided with a retaining ring 1192, the position of which corresponds to the position of the limiting ring 116. The retaining ring 1192 is used to press the circuit board 120 tightly onto the limiting ring 116 to prevent the ultraviolet rays emitted by the sterilization unit 130 from leaking out from the gap between the circuit board 120 and the limiting ring 116, ensuring that the ultraviolet rays can only be emitted from the clearance hole 117, thereby improving the sterilization efficiency. In this embodiment, the retaining ring 1192 and the limiting ring 116 are coaxially arranged, and the diameter of the retaining ring 1192 is less than or equal to the diameter of the limiting ring 116 to ensure the pressing effect.

[0040] In this embodiment, there are two of each of the following: limiting ring 116, clearance hole 117, holding ring 1192, and sterilization unit 130. The two sterilization units 130 are spaced apart and connected to the circuit board 120. Each sterilization unit 130 cooperates with one limiting ring 116, and each limiting ring 116 communicates with one clearance hole 117. The position of each holding ring 1192 corresponds to the position of one limiting ring 116. The two sterilization units 130 work together to improve the sterilization effect. However, this is not the only embodiment. In other embodiments, the number of limiting rings 116, clearance holes 117, and sterilization units 130 can be three or four. The specific number of these components is not limited.

[0041] Preferably, the top cover 119 has a plurality of clearance notches 1193 on the side near the base 118, and the plurality of clearance notches 1193 are spaced apart to facilitate the separation of the top cover 119 from the base 118. Further, the top cover 119 extends to be provided with a prying platform 1194, which is used to facilitate the application of force to detach the top cover 119 from the base 118.

[0042] In this embodiment, the base 118 is provided with a plurality of locking platforms 1181, which are arranged sequentially and spaced apart along the edge of the base 118. The top cover 119 is provided with a plurality of locking slots 1191, which are arranged sequentially and spaced apart along the edge of the top cover 119. Each locking slot 1191 engages with a locking platform 1181. The multiple locking slots 1191 and the multiple locking platforms 1181 work together to improve the locking effect and prevent the top cover 119 from accidentally detaching from the base 118, ensuring stability and reliability.

[0043] It should be noted that during the installation of the sterilization module 100, the circuit board 120 connected to the sterilization unit 130 is first installed onto the base 118; then the top cover 119 is placed on the base 118 and connected to it; next, the claw 115 is engaged with the copper tube 220, and the mounting hole 1141 of the connecting platform 114 is aligned with the threaded hole of the bracket 210; then the screw is passed through the mounting hole 1141 and tightened relative to the threaded hole to fix the relative position of the sterilization module 100 and the evaporator 200, thus completing the installation of the sterilization module 100, which is convenient and quick.

[0044] The sterilization module 100 of this embodiment has a sterilization unit 130 connected to a circuit board 120. The outer shell 110 is provided with a limiting post 111 and a latch 112. The circuit board 120 has a through hole 121, with the limiting post 111 engaging with the through hole 121 and the latch 112 engaging with the circuit board 120. Compared with the prior art, the sterilization module 100 provided by this invention, due to the use of an outer shell 110 connected to the evaporator 200 and limiting posts 111 and latches 112 engaging with the circuit board 120, can reduce the number of installation parts, simplify the installation process, improve installation efficiency, and optimize the limiting structure of the circuit board 120, facilitating disassembly and maintenance while ensuring the limiting effect.
