Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically, to a detection device and an air conditioner. Background Technology

[0002] Some air conditioner cabinet units on the market have a signal detection box on the air outlet frame of the indoor unit for collecting information. This signal detection box consists of a front shell and a rear cover. The rear cover covers the side of the front shell and together with the front shell, they form a cavity for housing the signal transceiver components.

[0003] This type of signal detection box is horizontally mounted on the air outlet frame, with its rear cover abutting against the air outlet frame. When the signal transceiver component malfunctions and needs repair, the rear cover is interfered with by the air outlet frame, and can only be opened after the box is completely removed from the air outlet frame, which is a cumbersome operation. Summary of the Invention

[0004] The problem solved by this invention is that existing signal detection boxes can only be opened when the air outlet frame is removed, which is cumbersome to operate and difficult to maintain.

[0005] To address the aforementioned problems, this invention provides a detection device that can be opened while mounted on the air outlet frame, is simple to operate, and is easy to maintain.

[0006] An embodiment of the present invention provides a detection device, comprising:

[0007] The upper housing has a mounting cavity with a bottom opening. Among the multiple side walls of the upper housing surrounding the mounting cavity, there is a light-transmitting side wall and a mounting side wall for contacting the air conditioner.

[0008] The lower box cover is connected to the upper box body from the bottom of the upper box body to seal the opening of the mounting cavity;

[0009] A bracket, which is housed within the mounting cavity and connected to the lower cover, is used to enter or exit the mounting cavity under the action of the lower cover.

[0010] A signal transceiver assembly, which is housed within the mounting cavity and connected to the bracket, is used to transmit and / or receive detection signals.

[0011] In practical applications, the testing device provided in this embodiment has its upper housing mounted against the air conditioner. When it is necessary to open the mounting cavity to remove the signal transceiver component, simply remove the cover from the bottom of the upper housing. The lower cover then pulls the bracket and the signal transceiver component mounted on the bracket out of the mounting cavity, allowing for the inspection and maintenance of the signal transceiver component. Therefore, the testing device provided in this embodiment can remove the signal transceiver component without removing the upper housing from the air conditioner, making the operation convenient, quick, and easy for maintenance.

[0012] In an optional embodiment, the signal transceiver assembly includes a circuit board, a transmitting probe, and a receiving probe. Both the transmitting probe and the receiving probe are electrically connected to the circuit board, and the circuit board is detachably connected to the bracket.

[0013] The circuit board and the bracket are detachably connected. In practical applications, after the lower cover drives the bracket and signal transceiver components out of the mounting cavity, the circuit board can be easily and quickly removed from the bracket, facilitating the inspection and maintenance of the circuit board, transmitting probe and receiving probe.

[0014] In an optional embodiment, the circuit board is rectangular, and a first positioning hole and a second positioning hole are respectively provided through the two opposite apex corners of the circuit board, and a first locking hole and a second locking hole are respectively provided through the remaining two opposite apex corners of the circuit board.

[0015] The bracket is provided with a first positioning post, a second positioning post, a first buckle, and a second buckle. The first positioning post is inserted into the first positioning hole, the second positioning post is inserted into the second positioning hole, the first buckle is fastened to the first buckle hole, and the second buckle is fastened to the second buckle hole.

[0016] The rectangular circuit board has a first locking hole and a second locking hole on one set of opposite corners, and a first positioning hole and a second positioning hole on the other set of opposite corners. When used with the bracket, it can achieve symmetrical and uniform fixation of the rectangular bracket on the two long sides and the two wide sides, thereby improving the installation stability of the circuit board.

[0017] In an optional embodiment, the circuit board is provided with a first mating wall, the transmitting probe protrudes from the first mating wall, and the receiving probe is connected to the first mating wall via pins.

[0018] In an optional embodiment, the first mating wall is further provided with a wiring terminal. When the circuit board is connected to the bracket, the wiring terminal corresponds to the end wall of one end of the bracket, and the end wall of the bracket away from the wiring terminal is provided with a foolproof protrusion.

[0019] The anti-misoperation protrusion serves to prevent reverse installation. If reverse installation occurs, the wiring terminal will be blocked by the anti-misoperation protrusion and will not be able to align with the end wall of the bracket, allowing the operator to correct the operation in time.

[0020] In an optional embodiment, the bottom end of the bracket is provided with a first notch, and the lower cover is provided with a second notch. The first notch and the second notch form a first mounting hole. The transmitting probe is installed in the first mounting hole. The bracket is also provided with a second mounting hole, and the receiving probe is installed in the second mounting hole.

[0021] The bracket and the lower cover together form a mounting hole for storing the transmitting probe, which improves the overall structural strength of the bracket and further enhances the stability of the transmitting probe.

[0022] In an optional embodiment, the detection device further includes a cylindrical seal, one end of which is embedded in the second mounting hole, and the other end of which abuts against the light-transmitting sidewall.

[0023] The cylindrical sealing element serves to isolate the receiving probe from the transmitting probe, preventing the signal emitted by the transmitting probe from being directly received by the receiving probe before it leaves the upper housing, thus improving the accuracy of the test results.

[0024] In an optional embodiment, the bracket is provided with a second mating wall and a third mating wall opposite to each other, the circuit board is provided with the second mating wall opposite to each other, the first mounting hole is a through hole extending from the second mating wall to the third mating wall, and the transmitting probe is embedded in the first mounting hole.

[0025] In an optional embodiment, there are multiple first notches and multiple second notches, and multiple first notches and multiple second notches correspond to form multiple first mounting holes. A groove is recessed on the second mating wall at a position between any two adjacent first notches. Multiple partition ribs are spaced out on the light-transmitting sidewall, and the multiple partition ribs are respectively embedded in the multiple grooves.

[0026] Multiple partition ribs protruding from the light-transmitting sidewall are embedded in multiple slots to isolate the multiple transmitting probes from each other, avoid mutual interference between the signals emitted by the multiple transmitting probes, and further improve the reliability and accuracy of the detection results.

[0027] In an optional embodiment, there are multiple transmitting probes and two receiving probes. The multiple transmitting probes and the two receiving probes are arranged sequentially at intervals along the same straight line on the circuit board, with the multiple transmitting probes positioned between the two receiving probes. The multiple transmitting probes are correspondingly installed in multiple first mounting holes, and there are two second mounting holes, with the two receiving probes correspondingly installed in the two second mounting holes.

[0028] Multiple transmitting probes and two receiving probes are arranged sequentially along the same straight line, with the two receiving probes located at both ends of the direction in which the multiple transmitting probes are arranged. This ensures that the receiving probes can more smoothly receive the signals reflected back from the multiple transmitting probes, further improving the reliability and accuracy of the detection results.

[0029] In an optional embodiment, the second mounting hole is a blind hole with an opening on the third mating wall, and the bottom wall of the second mounting hole has a pin hole extending to the second mating wall, through which the pin of the receiving probe passes and connects to the circuit board.

[0030] In an optional embodiment, a limiting ring is protruded on the second mating wall at the position corresponding to the second mounting hole, the circuit board is fitted with the limiting ring, and an avoidance gap is formed between the circuit board and the second mating wall.

[0031] Under the stopping action of the limiting ring, a clearance gap is formed between the circuit board and the second mating wall, avoiding large-area contact between the circuit board and the second mating wall, thus achieving effective protection of the circuit on the circuit board.

[0032] In an optional embodiment, a third positioning post and a third buckle are respectively erected on the lower box cover, and a third positioning hole and a third locking hole are respectively provided on the bracket. The third positioning post is inserted into the third positioning hole, and the third buckle is fastened to the third locking hole.

[0033] The bracket and the lower cover are quickly positioned by inserting the third positioning post and the third positioning hole, and the bracket is quickly assembled and disassembled on the lower cover by snapping the third buckle and the third buckle hole, thus improving assembly and disassembly efficiency.

[0034] In an optional embodiment, a hanging part protrudes from the side wall of the third card hole, and the third buckle extends into the third card hole and hangs with the hanging part. A limiting insert protrudes from the inner side of the top wall of the upper box body that forms the mounting cavity. The limiting insert is inserted into the third card hole from the side of the bracket away from the lower box cover and is located on the side of the third buckle away from the hanging part.

[0035] The limiting strip is inserted vertically downward into the third card hole. The third buckle is on the side opposite to the hanging part, thereby forming a stop and limiting effect on the third card hole, preventing the third card hole from detaching from the hanging part without human intervention, which would cause the bracket to separate from the lower cover.

[0036] In an optional embodiment, there are two third card holes arranged side by side and spaced apart. There are also two limiting strips, which are inserted into the two third card holes respectively, and the two limiting strips contact the two opposite sidewalls of the two third card holes respectively.

[0037] The two limiting inserts contact the two oppositely spaced side walls of the two third locking holes, thereby limiting the horizontal movement of the bracket and improving the overall structural stability.

[0038] In an optional embodiment, a first screw hole is provided through the lower box cover, and a second screw hole is provided on the upper box body. The lower box cover is connected to the upper box body by screwing a screw through the first screw hole and then into the second screw hole.

[0039] The lower cover is quickly and initially connected to the upper box body through the first screw hole, improving the convenience of disassembly and assembly.

[0040] In an optional embodiment, the lower cover is embedded in the mounting cavity, and the periphery of the lower cover is ultrasonically welded to the side wall of the mounting cavity.

[0041] The lower cover is embedded in the mounting cavity, and the periphery of the lower cover is ultrasonically welded to the side wall of the mounting cavity, which further improves the stability of the connection structure between the lower cover and the upper box body and enhances the sealing performance of the mounting cavity.

[0042] In an optional embodiment, the upper box body that forms the mounting cavity includes a first side wall and a second side wall among the multiple side walls, and both the first side wall and the second side wall are set at an angle to the light-transmitting side wall.

[0043] In an optional embodiment, guide ribs are protruding on the outer surfaces of both the first sidewall and the second sidewall, and the guide ribs are used to guide condensate water out of the light-transmitting sidewall.

[0044] The guide ribs are angled to guide the condensate to flow down quickly, preventing condensate from adhering to the light-transmitting sidewall for a long time and affecting the signal transmission effect.

[0045] In an optional embodiment, a mounting plate is provided at one end of the upper housing, the mounting plate is in the same plane as the mounting side wall, and a third screw hole is provided through the mounting plate for screws to pass through to connect the air conditioner.

[0046] In an optional embodiment, a fourth buckle is provided at the end of the upper housing away from the mounting plate, the fourth buckle being used to fasten with the air conditioner.

[0047] The fourth clip is used to quickly position the upper box with the air conditioner and fix one end of the upper box, ensuring that the third screw hole and the mating hole on the air conditioner are quickly positioned, thereby enabling the rapid installation of the upper box.

[0048] In an optional embodiment, a snap-fit ​​member protrudes from the mounting sidewall, and a fourth snap-fit ​​hole is provided through the snap-fit ​​member for fastening with the air conditioner.

[0049] The snap-fit ​​connector allows for quick attachment to the air conditioner, further enhancing the stability of the upper housing when installed on the air conditioner.

[0050] In an optional embodiment, a water-blocking ring is provided on the outer periphery of the top wall of the upper box, and the water-blocking ring and the outer side of the top wall of the upper box form a water-collecting pit. The water-collecting pit is used to collect condensate. A drainage gap is provided on the side of the water-blocking ring away from the light-transmitting sidewall. The drainage gap is used to guide the condensate collected in the water-collecting pit to the crossbeam of the air outlet frame of the air conditioner.

[0051] A drainage opening is made on the side of the water-blocking ring wall away from the light-transmitting side wall to guide the condensate accumulated in the water storage pit to the crossbeam of the air outlet frame of the air conditioner, so as to prevent the condensate accumulated at the top from overflowing onto the light-transmitting side wall and thus affecting signal transmission.

[0052] In an optional embodiment, the light-transmitting sidewall is disposed opposite to the mounting sidewall, and a wind-blocking rib is provided on the outer side of the top wall of the upper box. Compared with the mounting sidewall, the wind-blocking rib is closer to the light-transmitting sidewall, the extension direction of the wind-blocking rib is parallel to the light-transmitting sidewall, and a wind-guiding slope is provided on the side of the wind-blocking rib that is close to the mounting sidewall.

[0053] The inclined air guide surface directs the airflow from the side where the air conditioner is installed towards the light-transmitting side wall at an upward angle, preventing the air conditioner from blowing directly onto the light-transmitting side wall, thereby avoiding condensation on the light-transmitting side wall and improving the signal transmission effect.

[0054] The present invention also provides an air conditioner, including the aforementioned detection device, the detection device comprising:

[0055] The upper housing has a mounting cavity with a bottom opening. Among the multiple side walls of the upper housing surrounding the mounting cavity, there is a light-transmitting side wall and a mounting side wall for contacting the air conditioner.

[0056] The lower box cover is connected to the upper box body from the bottom of the upper box body to seal the opening of the mounting cavity;

Detailed Implementation

[0078] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0079] Please refer to the following: Figure 1 and Figure 2 , Figure 1 The diagram shown is a structural schematic of the indoor unit 10 of the air conditioner provided in this embodiment. Figure 2 As shown Figure 1 An enlarged schematic diagram of region A in the middle.

[0080] The air conditioner provided in this embodiment is a cross-flow air conditioner cabinet unit. The indoor unit 10 of the cross-flow air conditioner cabinet unit includes a housing 11, which has a columnar structure and is usually erected on the ground, which is equivalent to the housing 11 extending in the vertical direction. Correspondingly, the air outlet frame 12 of the indoor unit 10 is arranged vertically along the housing 11, and a detection device 100 is provided on the air outlet frame 12.

[0081] In fact, the indoor unit 10 of the air conditioner also includes a multi-section air guide assembly 13, which is arranged sequentially along the height direction on the air outlet frame 12, and the detection device 100 is horizontally arranged between any two adjacent air guide assemblies 13.

[0082] Please refer to the following: Figure 3 and Figure 4 , Figure 3 The diagram shown is a structural schematic of the detection device 100 provided in this embodiment. Figure 4 This is an exploded view of the detection device 100.

[0083] The detection device 100 includes an upper housing 110, a lower cover 120, a bracket 130, and a signal transceiver assembly 140. The upper housing 110 has a mounting cavity 111 with a bottom opening. Among the multiple sidewalls of the upper housing 110 surrounding the mounting cavity 111 are a light-transmitting sidewall 112 and a mounting sidewall 113 for contacting an air conditioner. The lower cover 120 is connected to the upper housing 110 from the bottom to seal the opening of the mounting cavity 111. The bracket 130 is housed within the mounting cavity 111 and connected to the lower cover 120, allowing it to enter or exit the mounting cavity 111 when moved by the lower cover 120. The signal transceiver assembly 140 is housed within the mounting cavity 111 and connected to the bracket 130, and is used to transmit and / or receive detection signals.

[0084] During the assembly process of the detection device 100, the signal transceiver component 140 is first installed on the bracket 130, and then the bracket 130 is installed on the lower cover 120. The lower cover 120 is then sealed by the side of the upper box body 110 corresponding to the opening of the mounting cavity 111, so that the bracket 130 and the signal transceiver component 140 installed on the lower cover 120 can be inserted into the mounting cavity 111 together. Finally, the lower cover 120 is connected to the upper box body 110, thus completing the assembly of the detection device 100.

[0085] With the detection device 100 installed on the air outlet frame 12, the mounting side wall 113 of the upper housing 110 abuts against the air outlet frame 12, and the light-transmitting side wall 112 of the upper housing 110 is horizontally oriented away from the air outlet frame 12. In this embodiment, the signal transceiver component 140 emits infrared signals and receives reflected infrared signals. The light-transmitting side wall 112 is transparent, ensuring that the signal transceiver component 140 can smoothly transmit and receive infrared signals.

[0086] If a fault occurs in the signal transceiver component 140, requiring its removal, the lower cover 120 is removed from the bottom of the upper housing 110. After the lower cover 120 separates from the upper housing 110, the bracket 130 and the signal transceiver component 140 are pulled out of the mounting cavity 111 together, allowing for subsequent maintenance, repair, or replacement of the signal transceiver component 140. The removal of the signal transceiver component 140 from the mounting cavity 111 can be completed without disassembling the upper housing 110, making it convenient and quick.

[0087] Furthermore, when reinstalling the signal transceiver component 140 into the mounting cavity 111, simply re-sealing the mounting cavity 111 with the lower cover 120 from the bottom of the upper housing 110 will allow the bracket 130 and the signal transceiver component 140 to re-enter the mounting cavity 111, thus completing the connection and fixation between the lower cover 120 and the upper housing 110. It is evident that the reinstallation of the signal transceiver component 140 does not require disassembly or reassembly of the upper housing 110 relative to the air outlet frame 12, making it convenient and quick.

[0088] Therefore, the detection device 100 provided in this embodiment can remove the signal transceiver component 140 without removing the upper box 110 from the air conditioner, making it convenient and quick to operate and easy to repair.

[0089] Please see Figure 5 , Figure 5 The diagram shown is a structural schematic of the signal transceiver component 140 in this embodiment.

[0090] The signal transceiver assembly 140 includes a circuit board 141, a transmitting probe 142, a receiving probe 143, and a terminal block 144. A first mating wall 1411 is provided on the circuit board 141. The transmitting probe 142 protrudes from the first mating wall 1411. The receiving probe 143 is connected to the first mating wall 1411 through a pin. The terminal block 144 protrudes from the first mating wall 1411. The transmitting probe 142, the receiving probe 143, and the terminal block 144 are all electrically connected to the internal circuitry of the circuit board 141.

[0091] In this embodiment, the circuit board 141 is rectangular. A first positioning hole 1412 and a second positioning hole 1413 are respectively provided at two opposite apex corners of the circuit board 141, and a first locking hole 1414 and a second locking hole 1415 are respectively provided at the remaining two opposite apex corners of the circuit board 141. The first positioning hole 1412 and the second positioning hole 1413 are used to insert into the bracket 130, enabling quick positioning of the circuit board 141 on the bracket 130. The first locking hole 1414 and the second locking hole 1415 are used to snap onto the bracket 130, enabling convenient and quick detachable connection between the circuit board 141 and the bracket 130.

[0092] Furthermore, the signal transceiver assembly 140 provided in this embodiment has three transmitting probes 142 and two receiving probes 143. The three transmitting probes 142 are arranged sequentially at intervals along the long side of the circuit board 141 on the first mating wall 1411. The two receiving probes 143 are distributed at both ends of the arrangement direction of the three transmitting probes 142, and are located within the area enclosed by the first positioning hole 1412, the second positioning hole 1413, the first locking hole 1414, and the second locking hole 1415. The wiring terminal 144 is disposed at one end of the circuit board 141 on the first mating wall 1411 along the length direction, and the wiring terminal 144 is located outside the area enclosed by the first positioning hole 1412, the second positioning hole 1413, the first locking hole 1414, and the second locking hole 1415.

[0093] Three transmitting probes 142 and two receiving probes 143 are arranged sequentially along the same straight line, with the two receiving probes 143 distributed at both ends of the direction in which the three transmitting probes 142 are arranged. This ensures that the receiving probes 143 can receive the signals reflected back after being emitted by the transmitting probes 142 more smoothly, thereby further improving the reliability and accuracy of the detection results.

[0094] Please refer to the following: Figure 6 and Figure 7 , Figure 6 The image shown is a structural schematic diagram of the bracket 130 from one viewpoint. Figure 7 The diagram shown is a structural schematic of the bracket 130 from another perspective.

[0095] The bracket 130 has a second mating wall 131 and a third mating wall 132 arranged opposite to each other. The bottom end of the bracket 130 has three spaced and parallel first notches 133 recessed. When the bracket 130 is installed on the lower cover 120, the three first notches 133 and the base form three holes for respectively installing three transmitting probes 142. The third mating wall 132 has two second mounting holes 1321 recessed at both ends of the three first notches 133, and the two receiving probes 143 are installed in the two second mounting holes 1321. Furthermore, both second mounting holes 1321 are blind holes, and the bottom wall of each second mounting hole 1321 has a pin hole 1322 extending to the second mating wall 131. The pins of the receiving probes 143 pass through the pin holes 1322 and connect to the first mating wall 1411 of the circuit board 141.

[0096] Corresponding to the structure in which the transmitting probe 142 protrudes from the first mating wall 1411, in this embodiment, the first notch 133 extends from the third mating wall 132 through the bracket 130 to the second mating wall 131, that is, the first notch 133 and the lower cover 120 form a through hole for the three transmitting probes 142 to extend into.

[0097] Considering that in practical applications, the infrared signals emitted by the three transmitting probes 142 are prone to mutual interference, affecting the smooth transmission of signals, in this embodiment, two recessed grooves 1323 are provided on the third mating wall 132, and the two recessed grooves 1323 are spaced apart between the three first notches 133. The light-transmitting side wall 112 of the upper housing 110 is provided with a structure corresponding to the two recessed grooves 1323. When the bracket 130 is installed in the mounting cavity 111, it achieves the isolation of two adjacent transmitting probes 142, avoiding mutual interference of the infrared signals emitted by adjacent transmitting probes 142.

[0098] Furthermore, corresponding to the first positioning hole 1412, the second positioning hole 1413, the first latching hole 1414, and the second latching hole 1415 opened on the circuit board 141, the second mating wall 131 of the bracket 130 is provided with a first positioning post 1311, a second positioning post 1312, a first latch 1313, and a second latch 1314. The first positioning post 1311 is inserted into the first positioning hole 1412, the second positioning post 1312 is inserted into the second positioning hole 1413, the first latch 1313 is latched into the first latching hole 1414, and the second latch 1314 is latched into the second latching hole 1415.

[0099] When the circuit board 141 and the bracket 130 are assembled, the first mating wall 1411 of the circuit board 141 corresponds to the second mating wall 131 of the bracket 130. Considering that circuits, various components, and solder joints are arranged on the circuit board 141, contact between the first mating wall 1411 and the second mating wall 131 may damage the circuit structure on the circuit board 141. Therefore, in this embodiment, two limiting rings 1315 are provided on the second mating wall 131 corresponding to the two ends of the circuit board 141 along its length. The two limiting rings 1315 fit against the first mating wall 1411 of the circuit board 141, resulting in a clearance gap between the first mating wall 1411 and the second mating wall 131.

[0100] As can be seen, the two limiting rings 1315 serve to prevent the circuit board 141 from making large-area contact with the bracket 130, thereby effectively protecting the circuit structure on the circuit board 141. In this embodiment, the two limiting rings are positioned on the second mating wall 131 corresponding to the second mounting hole 1321, achieving uniform support of the circuit board 141 and ensuring its stability.

[0101] To prevent the signal transceiver assembly 140 from being installed upside down, in this embodiment, one end of the bracket 130 is provided with a foolproof protrusion 134. In fact, the length of the circuit board 141 corresponds to the length of the bracket 130. When the circuit board 141 and the bracket 130 are correctly installed, the three transmitting probes 142 are embedded in the three first notches 133, the two receiving probes 143 are accommodated in the two second mounting holes 1321, and the sidewall of the wiring terminal 144 corresponds to the endwall of the bracket 130 away from the foolproof protrusion 134.

[0102] Therefore, if an operational error occurs and the signal transceiver assembly 140 is to be mounted upside down on the bracket 130, the terminal block 144 will be blocked by the foolproof protrusion 134 when the three transmitting probes 142 are aligned with the three first notches 133 and the two receiving probes 143 are aligned with the two second mounting holes 1321, causing the circuit board 141 to fail to connect smoothly to the bracket 130.

[0103] To enable rapid installation of the bracket 130 on the lower cover 120, in this embodiment, the bracket 130 is vertically provided with a third positioning hole 135 and a third locking hole 136, meaning that the extending directions of the third positioning hole 135 and the third locking hole 136 are parallel to the second mating wall 131 and the third mating wall 132. The third positioning hole 135 is used to insert into the lower cover 120, achieving precise and rapid positioning of the bracket 130 on the lower cover 120, and the third locking hole 136 is used to snap onto the lower cover 120, achieving rapid fixation of the bracket 130 on the lower cover 120.

[0104] In this embodiment, in order to ensure the connection stability of the bracket 130 on the lower cover 120, there are two third positioning holes 135 and two third locking holes 136. The two third positioning holes 135 are respectively located at both ends of the bracket 130 in the length direction, and the two third locking holes 136 are respectively located at the positions between the two ends of the three first notches 133 on the bracket 130 in the arrangement direction and the two second mounting holes 1321.

[0105] Please refer to the following: Figure 8 and Figure 9 , Figure 8 The diagram shown is a structural schematic of the lower cover 120 in this embodiment. Figure 9 The diagram shows the connection structure between the lower cover 120, the bracket 130, and the signal transceiver assembly 140.

[0106] A third positioning post 121 and a third latch 122 are erected on one side of the lower cover 120, corresponding to the third positioning hole 135 and the third latch hole 136 provided on the bracket 130. There are two third positioning posts 121 and two third latches 122. The two third positioning posts 121 are inserted into the two third positioning holes 135 respectively to achieve quick positioning of the bracket 130, and the two third latches 122 are fastened into the two latch holes respectively to achieve quick fixation of the bracket 130.

[0107] Both ends of the lower cover 120 are provided with first screw holes 123, two third positioning posts 121 are located between the two first screw holes 123, and two third latches 122 are located between the two third positioning posts 121. In practical applications, the lower cover 120 is connected and fixed to the upper box body 110 by screwing two screws into the two first screw holes 123.

[0108] Furthermore, the lower cover 120 has three second notches 124 protruding between the two third positioning posts 121. The three second notches 124 and the three first notches 133 at the bottom of the bracket 130 correspond to form three first mounting holes 125. The three transmitting probes 142 protruding on the first mating wall 1411 of the circuit board 141 are embedded into the three first mounting holes 125 from the side where the second mating wall 131 of the bracket 130 is located.

[0109] In practical applications, when assembling the bracket 130, signal transceiver component 140, and lower cover 120, the signal transceiver component 140 is first assembled onto the bracket 130. First, the first mating wall 1411 of the circuit board 141 is aligned with the second mating wall 131 of the bracket 130. The three transmitting probes 142 are aligned with the three first notches 133 on the bracket 130, and the wiring terminal 144 is positioned away from the anti-foolproof protrusion 134. Then, the pins of the two receiving probes 143 are passed through the pin holes 1322 on the bottom wall of the two second mounting holes 1321 and connected to the first mating wall 1411. Next, the first positioning post 1311 on the bracket 130 is passed through the first positioning hole 1412, and the second positioning post 1312 is passed through the second positioning hole 1413. The first latch 1313 is engaged with the first latch hole 1414, and the second latch 1314 is engaged with the second latch hole 1415. When the connection is complete, the three transmitting probes 142 naturally extend into the three first notches 133, that is, the signal transceiver assembly 140 and the bracket 130 are assembled.

[0110] After the signal transceiver assembly 140 and the bracket 130 are assembled, the bracket 130 and the lower cover 120 are assembled. The two third positioning posts 121 erected on the lower cover 120 are passed through the two third positioning holes 135 on the bracket 130, and the two third latches 122 are fastened into the two third latching holes 136 on the bracket 130. After fastening, the three second notches 124 protruding on the lower cover 120 are respectively fastened to the three first notches 133 on the bottom of the bracket 130, thus forming three first mounting holes 125. The three transmitting probes 142 are respectively housed within the three first mounting holes 125, and the assembly of the bracket 130 and the lower cover 120 is completed.

[0111] In this embodiment, the first notch 133 on the bracket 130 and the second notch 124 on the lower cover 120 together form a first mounting hole 125 for housing the transmitting probe 142. Compared with the prior art where the transmitting probe 142 is only mounted on the bracket 130, the structure is more stable, the first mounting hole 125 has higher strength, and it is more conducive to the stable transmission of infrared signals by the transmitting probe 142. Furthermore, the bracket 130 and the lower cover 120 are quickly positioned by the insertion of the third positioning post 121 into the third positioning hole 135, and the bracket 130 is quickly disassembled and assembled on the lower cover 120 by the engagement of the third buckle 122 into the third buckle hole 136, which greatly improves the efficiency of disassembly and assembly of the bracket 130 and the lower cover 120.

[0112] Please refer to the following: Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the upper box 110 in this embodiment from one viewpoint. Figure 11 This is a schematic diagram of the upper box 110 in this embodiment from another perspective.

[0113] In addition to the light-transmitting sidewall 112 and the mounting sidewall 113, the upper box body 110 also includes a top wall 114 opposite to the opening of the mounting cavity 111. The top wall 114, together with the light-transmitting sidewall 112 and the mounting sidewall 113, forms the mounting cavity 111. Furthermore, corresponding to the first screw hole 123 on the lower box cover 120, a second screw hole 115 is provided at the bottom end of the upper box body 110. When the lower box cover 120 is connected to the upper box body 110, the connection and fixation between the lower box cover 120 and the upper box body 110 can be achieved by passing a screw through the first screw hole 123 and screwing it into the second screw hole 115. Corresponding to the first screw hole 123, the upper box body 110 also has two second screw holes 115.

[0114] Furthermore, in order to ensure the connection strength between the lower cover 120 and the upper box body 110, as well as the sealing and waterproof performance of the mounting cavity 111, in this embodiment, the lower cover 120 is embedded in the mounting cavity 111, and the periphery of the lower cover 120 is ultrasonically welded to the side wall of the mounting cavity 111.

[0115] In this embodiment, the upper box 110 includes a first side wall 1121 and a second side wall 1123 among the multiple side walls that form the mounting cavity 111. The light-transmitting side wall 112 is connected to the first side wall 1121 and the second side wall 1123 at angles on its two opposite sides in the horizontal direction.

[0116] In practice, the sides of the first sidewall 1121 and the second sidewall 1123 furthest from the light-transmitting sidewall 112 are respectively connected to the two opposite sides of the mounting sidewall 113 in the horizontal direction. The first sidewall 1121, the light-transmitting sidewall 112, and the second sidewall 1123 together form a convex arc-shaped panel structure on the upper housing 110. In practical applications, the first sidewall 1121 and the second sidewall 1123 can also use the same light-transmitting material as the light-transmitting sidewall 112, so that the signal transceiver assembly 140 can obtain a wide-angle signal transmission and reception area, improve the signal transmission and reception angle, and further improve the detection effect.

[0117] Both the outer surfaces of the first sidewall 1121 and the second sidewall 1123 are provided with protruding guide ribs 1124, which are used to guide condensate water out of the light-transmitting sidewall 112. It should be noted that the protruding guide ribs 1124 on the first sidewall 1121 and the second sidewall 1123 are all inclined relative to the vertical direction, and the height of the end of the guide rib 1124 near the light-transmitting sidewall 112 in the vertical direction is higher than the height of the end away from the light-transmitting sidewall 112.

[0118] The guide ribs 1124 are angled to guide condensate water to flow down quickly, preventing condensate water from adhering to the light-transmitting sidewall 112 for a long time and affecting signal transmission. In addition to the function of rapid drainage, the guide ribs 1124 also improve the aesthetics of the upper housing 110.

[0119] A mounting plate 116 is provided at one end of the upper housing 110. The mounting plate 116 is in the same plane as the mounting side wall 113. A third screw hole 1161 is provided through the mounting plate 116 for screws to pass through and connect to the air conditioner. Furthermore, a fourth latch 117 is provided at the end of the upper housing 110 away from the mounting plate 116, which is used to fasten with the air conditioner. Additionally, a latching member 118 protrudes from the mounting side wall 113, and a fourth latching hole 1181 is provided through the latching member 118, which is also used to fasten with the air conditioner.

[0120] The fourth clip 117 quickly positions the upper housing 110 with the air conditioner and secures one end of the upper housing 110, ensuring that the third screw hole 1161 is quickly positioned with the mating hole on the air conditioner, thus enabling rapid installation of the upper housing 110. The snap-fit ​​connector 118 quickly engages with the air conditioner, further enhancing the stability of the upper housing 110 on the air conditioner.

[0121] Please continue reading. Figure 10 A water-blocking ring 1141 is provided on the outer periphery of the top wall 114 of the upper box 110. The water-blocking ring 1141 and the outer periphery of the top wall 114 of the upper box 110 form a water-collecting pit 1142. The water-collecting pit 1142 is used to collect condensate. A drainage gap 1143 is provided on the side of the water-blocking ring 1141 away from the light-transmitting side wall 112. The drainage gap 1143 is used to guide the condensate collected in the water-collecting pit 1142 to the crossbeam of the air outlet frame 12 of the air conditioner.

[0122] A drainage opening 1143 is provided on the side of the water-blocking ring wall 1141 away from the light-transmitting side wall 112, so as to guide the condensate accumulated in the water storage pit 1142 to the crossbeam of the air outlet frame 12 of the air conditioner, and prevent the condensate accumulated at the top from overflowing onto the light-transmitting side wall 112, thereby affecting signal transmission.

[0123] Furthermore, a wind-blocking rib 1144 is also provided on the outer side of the top wall 114 of the upper box 110. Compared with the mounting side wall 113, the wind-blocking rib 1144 is closer to the light-transmitting side wall 112. The extension direction of the wind-blocking rib 1144 is parallel to the light-transmitting side wall 112. A wind-guiding slope 1145 is provided on the side of the wind-blocking rib 1144 that is close to the mounting side wall 113.

[0124] It should be noted that the side of the air guide slope 1145 closest to the mounting side wall 113 is lower in the vertical direction than the side of the air guide slope 1145 closest to the light-transmitting side wall 112. In practical applications, after the air blown out by the air outlet frame 12 of the indoor unit 10 reaches the air guide slope 1145, the height of the air guide slope 1145 gradually increases, guiding the airflow vertically upward, that is, away from the light-transmitting side wall 112, to prevent the airflow from reaching the light-transmitting side wall 112, thereby avoiding excessive condensation on the light-transmitting side wall 112 and improving the signal transmission effect.

[0125] Please refer to the following: Figure 12 and Figure 13 , Figure 12 The image shown is a cross-sectional view of the detection device 100 provided in this embodiment from one perspective. Figure 13 The image shown is a cross-sectional view of the detection device 100 provided in this embodiment from another perspective.

[0126] The third card hole 136 has a protruding hanging part 1361 on its side wall. The third buckle 122 extends into the third card hole 136 and hangs with the hanging part 1361. The upper box body 110 has a protruding limiting insert 1146 on the inner side of the top wall 114 of the mounting cavity 111. The limiting insert 1146 is inserted into the third card hole 136 from the side of the bracket 130 away from the lower box cover 120 and is located on the side of the third buckle 122 away from the hanging part 1361.

[0127] The limiting insert 1146 is inserted vertically downward into the third card hole 136. The third buckle 122 is on the side away from the hanging part 1361, thereby forming a stop and limiting effect on the third card hole 136, preventing the third card hole 136 from detaching from the hanging part 1361 without human intervention, causing the bracket 130 to separate from the lower box cover 120.

[0128] Similarly, the number of limiting inserts 1146 corresponds to the number of third locking holes 136 provided on the bracket 130, which is also two. The two limiting inserts 1146 are spaced apart on the inner side of the top wall 114, and are respectively inserted into the two third locking holes 136, with each limiting insert 1146 contacting the two opposite sidewalls of the two third locking holes 136. This contact between the two limiting inserts 1146 and the two opposite sidewalls of the two third locking holes 136 effectively limits the horizontal movement of the bracket 130, improving the overall structural stability.

[0129] Please see Figure 14 , Figure 14 The image shown is a cross-sectional view of the detection device 100 provided in this embodiment from another perspective.

[0130] The detection device 100 also includes a cylindrical seal 150, one end of which is embedded in the second mounting hole 1321, the receiving probe 143 is housed in the cylindrical seal 150, and the other end of the cylindrical seal 150 abuts against the light-transmitting sidewall 112.

[0131] In fact, when the assembly is complete, the end of the cylindrical seal 150 extending out of the second mounting hole 1321 abuts against the light-transmitting sidewall 112 and deforms, forming a seal on the periphery of the second mounting hole 1321. This serves to isolate the receiving probe 143 from the transmitting probe 142, preventing the signal emitted by the transmitting probe 142 from being directly received by the receiving probe 143 before it leaves the upper housing 110, thereby improving the accuracy of the detection results.

[0132] It is understood that in other embodiments, a sealing gasket may be laid on the third mating wall 132 of the bracket 130 at the position between the two ends of the three first notches 133 and the two second mounting holes 1321, or a cylindrical sealing member 150 may be installed in the three first mounting holes 125 to seal the gap between the position between the first mounting hole 125 and the second mounting hole 1321 and the light-transmitting sidewall 112.

[0133] In addition, two partition ribs 1125 are provided at intervals on the light-transmitting sidewall 112, and the two partition ribs 1125 are respectively embedded in two recessed grooves 1323 on the third mating wall 132 of the bracket 130. This achieves isolation between any two adjacent transmitting probes 142, avoids mutual interference of signals emitted by the three transmitting probes 142, and further improves the reliability and accuracy of the detection results.

[0134] In summary, the detection device 100 provided in this embodiment, when installed on the air outlet frame 12 of the indoor unit 10, allows the signal transceiver component 140 to be removed without detaching the upper casing 110 from the air conditioner. This makes operation convenient, quick, and easy to maintain. The air conditioner provided in this embodiment is characterized by easy disassembly and assembly, and accurate and reliable detection results.

[0135] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
