Description

Technical Field

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

[0002] Currently, some air conditioner cabinet units on the market are equipped with detection devices to collect various information, including the location of a person, to achieve auxiliary functions such as preventing direct airflow. These current detection devices transmit and receive sensor signals through transmitting and receiving probes installed inside a light-transmitting casing. However, since various types of light can pass through the casing, other light sources can affect the transmission and reception of the sensor signals, leading to weakened signal strength, poor signal transmission and reception, and ultimately impacting the user experience. Summary of the Invention

[0003] The problem solved by this invention is how to improve the transmittance of the sensing signal, reduce the influence of other light sources, ensure the strength of the sensing signal, enhance the transmission and reception of the sensing signal, and improve the user experience.

[0004] To solve the above problems, the technical solution of the present invention is implemented as follows:

[0005] In a first aspect, the present invention provides a detection device, comprising a housing, a light-transmitting film, and a sensing component. The housing has an accommodating cavity, and the sensing component is installed within the accommodating cavity. The sensing component is used to transmit and / or receive sensing signals. The housing has a light-transmitting wall, and the light-transmitting film is attached to the light-transmitting wall to improve the light transmittance of the sensing signal. Compared with the prior art, the detection device provided by the present invention, due to the use of a sensing component installed within the accommodating cavity and a light-transmitting film attached to the outside of the light-transmitting wall, can improve the light transmittance of the sensing signal, reduce the influence of other light sources, ensure the strength of the sensing signal, enhance the sensing signal transmission and reception effect, and improve the user experience.

[0006] Furthermore, the sensing assembly includes a mounting bracket and a sensor. The sensor includes a circuit board, a signal transmitting probe, and a signal receiving probe. Both the signal transmitting probe and the signal receiving probe are connected to the circuit board, which is mounted on the mounting bracket. The mounting bracket can fix the position of the circuit board, thereby fixing the position of the signal transmitting probe and the signal receiving probe and preventing displacement of the signal transmitting probe and the signal receiving probe relative to the front and rear covers.

[0007] Furthermore, the transparent wall has light-transmitting holes, the positions of which correspond to the positions of the signal transmitting probe, and a light-transmitting film covers the outside of the light-transmitting holes. The sensing signal emitted by the signal transmitting probe passes through the light-transmitting holes and the light-transmitting film in sequence and is emitted outward.

[0008] Furthermore, the mounting bracket is equipped with support ribs that extend into the light-transmitting holes and are fitted snugly against the light-transmitting membrane. The support ribs support the light-transmitting membrane, thereby limiting its position and preventing deformation.

[0009] Furthermore, there are multiple signal transmitting probes and at least one support rib. The multiple signal transmitting probes are spaced apart on the circuit board, and at least one support rib is provided between two adjacent signal transmitting probes. The support rib can prevent the light-transmitting film from being recessed and deformed into the gap between two adjacent signal transmitting probes.

[0010] Furthermore, the sensing assembly also includes a sealing gasket, which is disposed between the mounting bracket and the light-transmitting wall. The sealing gasket has a clearance hole, the position of which corresponds to the positions of the signal transmitting probe and the light-transmitting hole. The sealing gasket is positioned between the signal transmitting probe and the signal receiving probe to prevent light leakage. The clearance hole is used to allow the sensing signal emitted by the signal transmitting probe to pass through the clearance hole, the light-transmitting hole, and the light-transmitting film in sequence and be emitted outward.

[0011] Furthermore, the sealing gasket is provided with sealing ribs that extend into the light-transmitting holes and are fitted into the light-transmitting membrane. The sealing ribs can support the light-transmitting membrane, thereby limiting its position and preventing deformation.

[0012] Furthermore, there are two sealing ribs, which are positioned opposite each other on both sides of the sealing gasket, with the signal transmitting probe located between the two sealing ribs. The sealing ribs enable the positioning of the sealing gasket, and by cooperating with the light-transmitting hole, they fix the relative position between the sealing gasket and the light-transmitting wall. The sealing ribs also further improve the light-blocking effect, ensuring that the signal transmitting probe and the signal receiving probe are completely separated.

[0013] Furthermore, the gasket is provided with a connecting post, and the mounting bracket has a mounting hole. The connecting post extends into the mounting hole and mates with it. The mounting hole can limit the connecting post to fix the relative position of the gasket and the mounting bracket, preventing the gasket from shifting relative to the mounting bracket.

[0014] Furthermore, the light-transmitting wall has a recessed groove, and the light-transmitting membrane is placed inside the recessed groove. The depth of the recessed groove is greater than or equal to the thickness of the light-transmitting membrane to ensure that the light-transmitting membrane is completely located inside the recessed groove, thereby effectively protecting the light-transmitting membrane and improving the aesthetics of the detection device.

[0015] Furthermore, the light-transmitting hole is offset within the recessed groove. This brings the light-transmitting hole closer to the center line of the air conditioner unit, thereby improving the accuracy of information collection.

[0016] Furthermore, there are two signal receiving probes, spaced apart on the circuit board, with a signal transmitting probe positioned between them. The two signal receiving probes work together to improve the accuracy of information acquisition.

[0017] Furthermore, the thickness of the portion of the transparent wall corresponding to the position of the signal receiving probe is less than the thickness of the rest of the transparent wall. This improves the light transmittance of the portion of the transparent wall corresponding to the position of the signal receiving probe while still providing shielding and protection, making it easier for the signal receiving probe to receive the sensing signal and improving the reception effect of the sensing signal.

[0018] Furthermore, the housing includes a front shell and a rear cover, which are connected and together form an accommodating cavity. A light-transmitting wall is located on the side of the front shell away from the rear cover to facilitate installation and maintenance.

[0019] Furthermore, the sensing assembly includes a mounting bracket and a sensor. The sensor is mounted on the mounting bracket, which is equipped with a resilient locking arm. The front housing is equipped with a latch, and the resilient locking arm engages with the latch to fix the relative position of the mounting bracket and the front housing, preventing the mounting bracket from shifting relative to the front housing.

[0020] Furthermore, the mounting bracket is provided with a retaining plate, which abuts against the rear cover. The rear cover can limit the mounting bracket through the retaining plate, so as to further fix the mounting bracket in the position of the accommodating cavity.

[0021] Furthermore, there are two abutment plates, which are positioned opposite each other on the mounting bracket. The circuit board of the sensing component is positioned between the two abutment plates. The rear cover has a clearance groove located between the two abutment plates to avoid interference between the solder joints on the circuit board and the rear cover, thus facilitating installation and removal.

[0022] Furthermore, the front housing and rear cover together form a wire passage hole, which communicates with the accommodating cavity. The axial direction of the wire passage hole is inclined towards the sensing component. The wire passage hole is used for the wires of the sensing component to pass through, so as to realize the power connection function of the sensing component.

[0023] Furthermore, a wire-passing sealing block is provided inside the wire-passing hole. The wire-passing direction of the sealing block is the same as the axis of the wire-passing hole. The sealing block is used for the lead-out of the sensing component's wires. The inclined wire-passing sealing block can minimize the overall size of the detection device while ensuring the wire-passing effect, and can also prevent the wires from being damaged due to excessive bending.

[0024] Furthermore, the rear cover is equipped with a sealing plate, and there is a gap between the front cover and the rear cover, which communicates with the wiring hole. The sealing plate is placed above the gap to prevent condensate from flowing into the wiring hole through the gap. This effectively protects the sensing components inside the cavity from damage caused by water.

[0025] Furthermore, the front shell and rear cover are ultrasonically welded to improve the connection strength and sealing performance between them, thus providing a waterproof effect.

[0026] Furthermore, the light-transmitting film is made of polyester resin or polymethyl methacrylate. It can improve the transmittance of infrared light and reduce the influence of other light sources.

[0027] Furthermore, the light-transmitting film includes an overlapping film body and a light-blocking adhesive layer. The film body is bonded to the light-transmitting wall via the light-blocking adhesive layer. The light-blocking adhesive layer has a first light-leaking hole and a second light-leaking hole. The position of the first light-leaking hole corresponds to the position of the transmitting end of the sensing component, and the position of the second light-leaking hole corresponds to the position of the receiving end of the sensing component. The sensing signal emitted by the transmitting end (signal transmitting probe) of the sensing component can pass through the light-transmitting hole, the clearance hole, the first light-leaking hole, and the film body in sequence and be emitted outward. The reflected sensing signal passes through the film body, the second light-leaking hole, and the light-transmitting wall in sequence and is received by the receiving end (signal receiving probe) of the sensing component.

[0028] Secondly, the present invention provides an air conditioner, including an air outlet frame and the aforementioned detection device. The detection device is installed on the air outlet frame and includes a housing, a light-transmitting film, and a sensing component. A cavity is provided within the housing, and the sensing component is installed within the cavity. The sensing component is used to transmit and / or receive sensing signals. The housing has a light-transmitting wall, and the light-transmitting film is attached to the light-transmitting wall to improve the light transmittance of the sensing signal. The air conditioner can improve the light transmittance of the sensing signal, reduce the influence of other light sources, ensure the strength of the sensing signal, enhance the transmission and reception of the sensing signal, and improve the user experience.

[0029] Furthermore, the housing includes a front shell and a rear cover that are connected to each other. A water collection groove is provided on the top surface of the front shell, and a drainage channel is provided on the side of the rear cover near the air outlet frame. The water collection groove is connected to the drainage channel. The water collection groove is used to collect condensate on the front shell and guide the condensate into the drainage channel. The drainage channel is used to quickly drain the condensate on the top surface of the front shell, resulting in good drainage, avoiding water blowing, and improving the user experience.

[0030] Furthermore, the air outlet frame is equipped with a crossbeam, and the rear cover is fitted to the crossbeam, together forming a drainage cavity. The crossbeam has drainage holes communicating with the drainage cavity. A drainage channel is located within the drainage cavity, with the position of the drainage channel corresponding to the position of the drainage holes. The drainage holes are used to drain condensate from the drainage channel and also to allow condensate flowing into the drainage cavity through the gap between the rear cover and the crossbeam to flow out. Condensate flowing out of the drainage channel and condensate flowing into the drainage cavity through the gap between the rear cover and the crossbeam can both flow out through the drainage holes to guide the condensate and prevent condensate accumulation.

[0031] Furthermore, the air outlet frame has an air outlet, and there are two detection devices. The two detection devices are spaced apart along the length of the air outlet to divide the air outlet into three sections. This facilitates independent airflow control for the three air outlet sections and improves the user experience. Attached Figure Description

Detailed Implementation

[0047] 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.

[0048] First Embodiment

[0049] Please refer to the reference. Figures 1 to 5 This invention provides a detection device 100 for transmitting and receiving sensor signals. It can improve the transmittance of sensor signals, reduce the influence of other light sources, ensure the strength of sensor signals, enhance the transmission and reception of sensor signals, and improve the user experience.

[0050] It should be noted that the detection device 100 is applied to an air conditioner cabinet unit. The air conditioner cabinet unit is placed on the ground and can blow out hot or cold air to achieve the function of heating or cooling. The detection device 100 is used to collect various information, including the location of the human body, to achieve auxiliary functions such as preventing direct airflow.

[0051] The detection device 100 includes a housing 170, a light-transmitting film 130, and a sensing component 140. A cavity 150 is provided within the housing 170, and the sensing component 140 is installed within the cavity 150. The sensing component 140 is used to transmit and / or receive sensing signals for information acquisition, facilitating the implementation of various functions of the air conditioner unit. A light-transmitting wall 111 is provided within the housing 170, and the light-transmitting film 130 is attached to the light-transmitting wall 111. The light-transmitting film 130 is used to improve the light transmittance of the sensing signal, reduce the influence of other light sources, ensure the strength of the sensing signal, enhance the transmission and reception of the sensing signal, and improve the user experience.

[0052] In this embodiment, the housing 170 includes a front shell 110 and a rear cover 120. The front shell 110 and the rear cover 120 are connected and together form an accommodating cavity 150 for easy installation and maintenance. The front shell 110 and the rear cover 120 work together to shield and protect the sensing component 140. Specifically, a light-transmitting wall 111 is disposed on the side of the front shell 110 away from the rear cover 120, and a light-transmitting film 130 is attached to the side of the light-transmitting wall 111 away from the accommodating cavity 150. However, this is not the case. In other embodiments, the housing 170 may also include an upper shell and a lower cover connected to each other, and the light-transmitting film 130 may also be attached to the side of the light-transmitting wall 111 near the accommodating cavity 150.

[0053] Specifically, during the process of transmitting and receiving sensing signals, the sensing component 140 emits a sensing signal, which passes through the light-transmitting film 130 and is reflected after illuminating the target object. The reflected signal passes through the light-transmitting film 130 and is received by the sensing component 140, thereby realizing the information acquisition function of the sensing component 140. In this process, because the light-transmitting film 130 can improve the light transmittance of the sensing signal and reduce the influence of other light, the sensing signal strength is high and the transmission and reception effect is good.

[0054] In this embodiment, the sensing signal is an infrared signal. The sensing component 140 achieves information acquisition by emitting and receiving infrared light. The light-transmitting film 130 can improve the transmittance of infrared light and reduce the influence of other light sources. However, it is not limited to this. In other embodiments, the sensing signal can also be a radio frequency signal. The sensing component 140 achieves information acquisition by emitting and receiving radio waves. The type of sensing signal is not specifically limited.

[0055] The sensing assembly 140 includes a mounting bracket 141, a sensor 142, and a sealing gasket 143. The sensor 142 is mounted on the mounting bracket 141, which connects the front housing 110 and the rear cover 120 to fix the position of the sensor 142 and prevent displacement of the sensor 142 relative to the front housing 110 and the rear cover 120. The sealing gasket 143 is mounted on the mounting bracket 141 and serves to separate the signal transmitting end and the signal receiving end of the sensor 142 to improve the accuracy of information acquisition.

[0056] Sensor 142 includes a circuit board 1421, a signal transmitting probe 1422, and a signal receiving probe 1423. Both the signal transmitting probe 1422 and the signal receiving probe 1423 are connected to the circuit board 1421. The signal transmitting probe 1422 emits a sensing signal, and the signal receiving probe 1423 receives the reflected sensing signal. The signal transmitting probe 1422 and the signal receiving probe 1423 work together to transmit and receive the sensing signal. The circuit board 1421 is mounted on a mounting bracket 141, which fixes the position of the circuit board 1421, thereby fixing the positions of the signal transmitting probe 1422 and the signal receiving probe 1423 and preventing displacement of the signal transmitting probe 1422 relative to the front cover 110 and the rear cover 120.

[0057] In this embodiment, the light-transmitting wall 111 has a light-transmitting hole 112, which is connected to the accommodating cavity 150. The position of the light-transmitting hole 112 corresponds to the position of the signal transmitting probe 1422. The light-transmitting film 130 covers the outside of the light-transmitting hole 112. The sensing signal emitted by the signal transmitting probe 1422 passes through the light-transmitting hole 112 and the light-transmitting film 130 in sequence and is emitted outward. During this process, since there is no obstruction from the light-transmitting wall 111, the sensing signal emitted by the signal transmitting probe 1422 is stronger, which further improves the transmission effect of the sensing signal.

[0058] Specifically, since the circuit board 1421 has a terminal block 1424 at its end, which occupies some space, the signal transmitting probe 1422 is not located in the middle of the circuit board 1421, but is located at a position offset from the middle of the circuit board 1421 away from the terminal block 1424. Also, since the middle of the circuit board 1421 is aligned with the middle of the front housing 110, and the light-transmitting wall 111 is located in the middle of the front housing 110, the light-transmitting hole 112 is not located in the middle of the light-transmitting wall 111, but is located at a position offset from the middle of the light-transmitting wall 111 away from the terminal block 1424, so as to ensure that the position of the light-transmitting hole 112 corresponds to the position of the signal transmitting probe 1422.

[0059] Furthermore, the mounting bracket 141 is provided with a support rib 1411, which extends into the light-transmitting hole 112 and is fitted to the light-transmitting film 130. The support rib 1411 can support the light-transmitting film 130 to limit the position of the light-transmitting film 130 and prevent the light-transmitting film 130 from deforming.

[0060] Specifically, there are multiple signal transmitting probes 1422 and at least one support rib 1411. The multiple signal transmitting probes 1422 are spaced apart on the circuit board 1421, and they work together to improve the accuracy of information acquisition. At least one support rib 1411 is provided between two adjacent signal transmitting probes 1422. The support rib 1411 prevents the light-transmitting film 130 from concave or deforming into the gap between the two adjacent signal transmitting probes 1422.

[0061] In this embodiment, there are three signal transmitting probes 1422 and two support ribs 1411, but it is not limited to this. In other embodiments, there may be four signal transmitting probes 1422 and three support ribs 1411; or there may be two signal transmitting probes 1422 and one support rib 1411. The number of signal transmitting probes 1422 and support ribs 1411 is not specifically limited.

[0062] In this embodiment, there are two signal receiving probes 1423, which are spaced apart on the circuit board 1421. Three signal transmitting probes 1422 are located between the two signal receiving probes 1423. The two signal receiving probes 1423 work together to improve the accuracy of information acquisition.

[0063] It should be noted that all three signal transmitting probes 1422 are located inside the light-transmitting hole 112, while the two signal receiving probes 1423 are located outside the light-transmitting hole 112. The position of the signal receiving probe 1423 corresponds to the position of the light-transmitting wall 111. The reflected sensing signal passes through the light-transmitting film 130 and the light-transmitting wall 111 in sequence and is received by the signal receiving probe 1423. The light-transmitting wall 111 can shield and protect the signal receiving probe 1423 to improve the reliability of signal reception.

[0064] Specifically, the thickness of the portion of the light-transmitting wall 111 corresponding to the position of the signal receiving probe 1423 is less than the thickness of the remaining portion of the light-transmitting wall 111. This improves the light transmittance of the portion of the light-transmitting wall 111 corresponding to the position of the signal receiving probe 1423 while providing shielding and protection. This makes it easier for the signal receiving probe 1423 to receive the sensing signal, thus improving the reception effect of the sensing signal.

[0065] It is worth noting that the sealing gasket 143 is installed on the mounting bracket 141 and positioned between the mounting bracket 141 and the light-transmitting wall 111. The sealing gasket 143 is positioned between the signal transmitting probe 1422 and the signal receiving probe 1423, and is used to separate the signal transmitting probe 1422 and the signal receiving probe 1423 to prevent light leakage. The sealing gasket 143 has a clearance hole 1431, the position of which corresponds to the positions of the signal transmitting probe 1422 and the light-transmitting hole 112. The clearance hole 1431 is used to allow clearance for the sensing signal emitted by the signal transmitting probe 1422, so that the sensing signal emitted by the signal transmitting probe 1422 can pass through the clearance hole 1431, the light-transmitting hole 112 and the light-transmitting film 130 in sequence and be emitted outward.

[0066] In this embodiment, the sealing gasket 143 is disposed around the light-transmitting hole 112 to seal the periphery of the light-transmitting hole 112, thereby separating the signal transmitting probe 1422 and the signal receiving probe 1423. This prevents the sensing signal emitted by the signal transmitting probe 1422 from being directly refracted to the signal receiving probe 1423 instead of being emitted to the outside, thus further improving the accuracy of information acquisition.

[0067] Furthermore, the sealing gasket 143 is provided with a sealing rib 1432, which extends into the light-transmitting hole 112 and is fitted to the light-transmitting film 130. The sealing rib 1432 can support the light-transmitting film 130 to limit the position of the light-transmitting film 130 and prevent the light-transmitting film 130 from deforming.

[0068] In this embodiment, there are two sealing ribs 1432, which are arranged opposite each other on both sides of the sealing gasket 143, and the signal transmitting probe 1422 is located between the two sealing ribs 1432. Specifically, both sealing ribs 1432 are embedded in the light-transmitting hole 112 and are arranged opposite each other on both sides of the light-transmitting hole 112. On the one hand, the sealing ribs 1432 can position the sealing gasket 143. By cooperating with the light-transmitting hole 112, the sealing gasket 143 and the light-transmitting wall 111 are fixed in relative position, preventing the sealing gasket 143 from shifting relative to the light-transmitting wall 111. On the other hand, the sealing ribs 1432 can further improve the light blocking effect, ensuring that the signal transmitting probe 1422 and the signal receiving probe 1423 are completely separated, preventing light leakage.

[0069] In this embodiment, the sealing gasket 143 is provided with a connecting post 1433, and the mounting bracket 141 has a mounting hole 1412. The connecting post 1433 extends into the mounting hole 1412 and cooperates with it. The mounting hole 1412 can limit the connecting post 1433 to fix the relative position of the sealing gasket 143 and the mounting bracket 141, preventing the sealing gasket 143 from shifting relative to the mounting bracket 141. Specifically, there are two connecting posts 1433 and two mounting holes 1412. The two connecting posts 1433 are respectively located at two opposite corners of the sealing gasket 143, and each connecting post 1433 cooperates with one mounting hole 1412 to improve the stability of the connection between the sealing gasket 143 and the mounting bracket 141.

[0070] The light-transmitting film 130 includes an overlapping film body 131 and a light-blocking adhesive layer 132. The film body 131 is bonded to the light-transmitting wall 111 by the light-blocking adhesive layer 132. The light-blocking adhesive layer 132 has both light-blocking and adhesive properties. The light-blocking adhesive layer 132 is used to prevent light leakage and also to bond and fix the relative positions of the film body 131 and the light-transmitting wall 111. Specifically, the light-blocking adhesive layer 132 has a first light-leaking hole 133 and a second light-leaking hole 134. The position of the first light-leaking hole 133 corresponds to the position of the transmitting end (signal transmitting probe 1422) of the sensing component 140. The sensing signal emitted by the signal transmitting probe 1422 can pass through the light-transmitting hole 112, the clearance hole 1431, the first light-leaking hole 133 and the membrane body 131 in sequence and be emitted outward. The position of the second light-leaking hole 134 corresponds to the position of the receiving end (signal receiving probe 1423) of the sensing component 140. The reflected sensing signal passes through the membrane body 131, the second light-leaking hole 134 and the light-transmitting wall 111 in sequence and is received by the signal receiving probe 1423.

[0071] In this embodiment, there are three first light leakage holes 133, and the position of each first light leakage hole 133 corresponds to the position of a signal transmitting probe 1422; there are two second light leakage holes 134, and the position of each second light leakage hole 134 corresponds to the position of a signal receiving probe 1423.

[0072] It should be noted that the light-blocking adhesive layer 132 has a total light-leakage hole (not shown in the figure), and four light-blocking strips 135 are arranged in parallel at intervals within the total light-leakage hole. The four light-blocking strips 135 work together to divide the total light-leakage hole into five light-leakage holes, namely three first light-leakage holes 133 and two second light-leakage holes 134. The three first light-leakage holes 133 are all located between the two second light-leakage holes 134. Furthermore, all four light-shielding strips 135 have light-shielding properties. Each light-shielding strip 135 is used to separate two adjacent light-leaking holes to prevent light leakage. All four light-shielding strips 135 are adhesive. Two light-shielding strips 135 are attached to the two support ribs 1411 of the mounting bracket 141 in a one-to-one correspondence, and the other two light-shielding strips 135 are attached to the two sealing ribs 1432 of the sealing gasket 143 in a one-to-one correspondence, so as to improve the stability of the connection between the front shell 110, the sensing component 140 and the light-transmitting film 130 and prevent the film body 131 from deforming.

[0073] In this embodiment, the mounting bracket 141 is provided with elastic locking arms 1413, and the front shell 110 is provided with buckles 115. The elastic locking arms 1413 and buckles 115 engage to fix the relative position of the mounting bracket 141 and the front shell 110, preventing the mounting bracket 141 from shifting relative to the front shell 110. Specifically, there are two elastic locking arms 1413 and two buckles 115. The two elastic locking arms 1413 are respectively located at two opposite corners of the mounting bracket 141, and each elastic locking arm 1413 engages with one buckle 115 to improve the stability of the connection between the mounting bracket 141 and the front shell 110.

[0074] Please refer to the reference. Figure 6 and Figure 7 In this embodiment, the mounting bracket 141 is provided with a support plate 1414, which abuts against the rear cover 120. The rear cover 120 can limit the mounting bracket 141 through the support plate 1414 to further fix the mounting bracket 141 in the position of the accommodating cavity 150.

[0075] Specifically, there are two abutment plates 1414, which are disposed opposite to each other on the mounting bracket 141. The circuit board 1421 is disposed between the two abutment plates 1414. The rear cover 120 has a clearance groove 121, which is located between the two abutment plates 1414. The clearance groove 121 is used to avoid the solder joints on the circuit board 1421 to prevent interference between the solder joints on the circuit board 1421 and the rear cover 120, and facilitates installation and disassembly.

[0076] In this embodiment, the light-transmitting wall 111 has a recess 113, and the light-transmitting film 130 is disposed in the recess 113. The depth of the recess 113 is greater than or equal to the thickness of the light-transmitting film 130, so as to ensure that the light-transmitting film 130 is completely located in the recess 113, thereby effectively protecting the light-transmitting film 130 and improving the aesthetics of the detection device 100.

[0077] It is worth noting that the light-transmitting hole 112 is offset within the recess 113, meaning it is not located in the center of the recess 113. Specifically, since air conditioner units are generally placed off-center, the air vents are positioned to the left or right relative to the unit's centerline. The offset light-transmitting hole 112 compensates for this offset, bringing both the light-transmitting hole 112 and the corresponding signal transmitting probe 1422 closer to the unit's centerline. This also brings the signal receiving probe 1423 closer to the unit's centerline. The proximity of the signal transmitting and receiving probes 1422 to the centerline effectively improves the accuracy of the detection distance, thereby further enhancing the accuracy of information collection.

[0078] Please refer to the reference. Figure 8 , Figure 9 and Figure 10 In this embodiment, the front shell 110 and the rear cover 120 together form a wire passage hole 160, which communicates with the accommodating cavity 150. The axial direction of the wire passage hole 160 is inclined to the sensing component 140. The wire passage hole 160 is used for the wires of the sensing component 140 to pass through, so as to realize the power connection function of the sensing component 140.

[0079] Furthermore, a wire-passing sealing block 161 is provided inside the wire-passing hole 160. The wire-passing direction of the wire-passing sealing block 161 is the same as the axial direction of the wire-passing hole 160, and it is also inclined to the sensing component 140. The wire-passing sealing block 161 is used for the lead-out of the wires of the sensing component 140. Specifically, the inclined wire-passing sealing block 161 can minimize the volume of the entire detection device 100 while ensuring the wire-passing effect, and can prevent the wires from being damaged due to excessive bending.

[0080] In this embodiment, the rear cover 120 is provided with a sealing plate 122. There is a gap 180 between the front shell 110 and the rear cover 120. The gap 180 is formed when the front shell 110 and the rear cover 120 are assembled to form the wire passage hole 160. The gap 180 communicates with the wire passage hole 160. The sealing plate 122 is placed above the gap 180 and is used to shield the gap 180 to prevent condensate from flowing into the wire passage hole 160 through the gap 180. This prevents condensate from flowing into the accommodating cavity 150 through the wire passage hole 160, thereby effectively protecting the sensing component 140 in the accommodating cavity 150 and preventing it from being damaged by water.

[0081] In this embodiment, the front shell 110 and the rear cover 120 are ultrasonically welded to improve the connection strength and sealing of the front shell 110 and the rear cover 120, thereby achieving a waterproof effect. However, this is not the only option. In other embodiments, the front shell 110 and the rear cover 120 can be connected by screws or adhesives, and the connection method between the front shell 110 and the rear cover 120 is not specifically limited.

[0082] In this embodiment, the light-transmitting film 130 is made of polyester resin material, which can improve the transmittance of infrared light and reduce the influence of other light. However, it is not limited to this. In other embodiments, the light-transmitting film 130 may also be made of polymethyl methacrylate material. The material of the light-transmitting film 130 is not specifically limited.

[0083] The detection device 100 of this embodiment of the invention has a housing 170 with a cavity 150. A sensing component 140 is installed in the cavity 150 and is used to transmit and / or receive sensing signals. The housing 170 has a light-transmitting wall 111, and a light-transmitting film 130 is attached to the light-transmitting wall 111 to improve the light transmittance of the sensing signal. Compared with the prior art, the detection device 100 provided by this invention, by using the sensing component 140 installed in the cavity 150 and the light-transmitting film 130 attached to the light-transmitting wall 111, can improve the light transmittance of the sensing signal, reduce the influence of other light, ensure the strength of the sensing signal, enhance the sensing signal transmission and reception effect, and improve the user experience.

[0084] Second Embodiment

[0085] Please refer to the reference. Figure 11 , Figure 12 and Figure 13 This invention provides an air conditioner 10 for regulating indoor temperature. The air conditioner 10 includes a detection device 100 and an air outlet frame 200. The basic structure, principle, and technical effects of the detection device 100 are the same as in the first embodiment. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0086] In this embodiment, the air conditioner 10 is a cabinet air conditioner, and the air outlet frame 200 has an air outlet 210. The airflow generated by the air conditioner 10 can be blown outward through the air outlet 210 to achieve the function of heating or cooling. The detection device 100 is installed on the air outlet frame 200 and located outside the air outlet 210. The detection device 100 is used to realize the information collection function.

[0087] It is worth noting that a water collection groove 114 is provided on the top surface of the front cover 110, and a drainage channel 123 is provided on the side of the rear cover 120 near the air outlet frame 200. The water collection groove 114 is connected to the drainage channel 123. The water collection groove 114 is used to collect condensate on the front cover 110 and guide the condensate into the drainage channel 123. The drainage channel 123 is used to quickly drain the condensate on the top surface of the front cover 110, which has a good drainage effect, avoids water blowing phenomenon, and improves user experience.

[0088] Specifically, when the air conditioner 10 regulates the indoor temperature, the airflow passes through the air outlet 210 and blows into the room. During this process, due to the uneven temperature between the inside and outside, condensation will be generated on the top surface of the front shell 110. The condensation will flow into the drain ditch 123 under the action of the water collection tank 114 to realize the function of draining condensation.

[0089] It should be noted that the air outlet frame 200 is equipped with a crossbeam 220, and the detection device 100 is detachably connected to the crossbeam 220. The rear cover 120 is fitted to the crossbeam 220, and the rear cover 120 and the crossbeam 220 work together to install the vertical guide vane 230 and limit the vertical guide vane 230. The rear cover 120 and the crossbeam 220 together form a drainage cavity 240, and the crossbeam 220 has a drainage hole 221 that communicates with the drainage cavity 240. A drainage channel 123 is set in the drainage cavity 240, and the position of the drainage channel 123 corresponds to the position of the drainage hole 221. The drainage hole 221 is used to drain the condensate in the drainage channel 123, and the drainage hole 221 is also used to allow the condensate that flows into the drainage cavity 240 through the gap between the rear cover 120 and the crossbeam 220 to flow out. Specifically, the condensate flowing out of the drainage ditch 123 and the condensate flowing into the drainage cavity 240 from the gap between the rear cover 120 and the crossbeam 220 can both flow out through the drainage hole 221 to guide the condensate and prevent the condensate from accumulating.

[0090] In this embodiment, there are two crossbeams 220 and two detection devices 100. The two crossbeams 220 are arranged in parallel and spaced apart in the air outlet frame 200. The two detection devices 100 are arranged spaced apart along the length of the air outlet 210. Each detection device 100 is installed on one crossbeam 220 to divide the air outlet 210 into three sections. Each section of the air outlet 210 is provided with a set of vertical air guide vanes 230 to facilitate independent air outlet control of the three sections of the air outlet 210 and improve the user experience.

[0091] The beneficial effects of the air conditioner 10 described in this embodiment are the same as those of the first embodiment, and will not be repeated here.

[0092] 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.
