Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of air conditioning, and in particular relates to a dustproof net and an air conditioner. Background Art
[0002] Air conditioners used in high-dust environments such as mine warehouses are equipped with dust screens at the condenser to filter external dust. When dust accumulates on the dust screen, the air volume and cooling capacity of the air conditioner will be reduced, and the dust screen needs to be cleaned regularly.
[0003] In the related art, a reminder of dust screen dirtiness is set in advance according to the usage time of the air conditioner. When the usage time of the air conditioner exceeds the set reminder time, the air conditioner will send a reminder signal that the dust screen is dirty and needs to be cleaned, reminding the user to clean the dust on the dust screen in time. Alternatively, a manual regular visual inspection method is used to determine the dirtiness of the air conditioner's dust screen, and then the dust screen is cleaned according to the manual judgment.
[0004] However, the method of setting reminders based on the air conditioner usage time is easily affected by environmental changes. If a high dust pollution environment is encountered, dust will accumulate on the dust screen quickly, and the signal indicating that the dust screen is dirty and blocked will not be timely. The method of manually visually judging the dirtiness and blockage on a regular basis is both inaccurate and wastes manpower. Utility Model Content
[0005] The embodiment of the present disclosure provides a dust screen and an air conditioner, which can accurately and automatically detect the dirt and blockage on the dust screen of the air conditioner. The technical solution is as follows:
[0006] The disclosed embodiment provides a dustproof net and an air conditioner, comprising an infrared emitting source, an infrared receiver, a partition and a net body. The infrared emitting source and the infrared receiver are both located on the same side of the net body, and the transmitting port of the infrared emitting source and the receiving port of the infrared receiver are both facing the net body. The partition is located between the infrared emitting source and the infrared receiver, and there is a gap between the partition and the net body. The infrared receiver is configured to receive infrared light reflected by the net body.
[0007] In an implementation of the present disclosure, the orthographic projections of the infrared emitting source and the infrared receiver on the plane where the partition is located are both located inside the partition.
[0008] In another implementation of the present disclosure, the dustproof net further includes a connector, and the infrared ray transmitting source and the infrared ray receiver are both connected to the same surface of the connector.
[0009] In yet another implementation of the present disclosure, a side of the connector connected to the infrared emitting source is parallel to the mesh body.
[0010] In yet another implementation of the present disclosure, the dustproof net further includes a mounting bracket, one end of the mounting bracket is connected to the connector, and the other end of the mounting bracket is connected to the net body.
[0011] In yet another implementation of the present disclosure, the dustproof net further includes a controller, and the controller is electrically connected to the infrared emission source and the infrared receiver respectively.
[0012] In another implementation of the present disclosure, the dustproof net further includes a warning light. The warning light is located on a side of the net body away from the infrared emitting source. The warning light is electrically connected to the controller.
[0013] An embodiment of the present disclosure provides an air conditioner, comprising the dustproof net.
[0014] In yet another implementation of the present disclosure, the air conditioner includes a condenser, the condenser is spaced apart from the dustproof net, and the infrared emitting source and the infrared receiver are both located between the condenser and the net body.
[0015] In yet another implementation of the present disclosure, the air conditioner includes a mounting bar, and the mounting bar is detachably connected to an edge of the dustproof net.
[0016] The technical solution provided by the embodiments of the present disclosure brings the following beneficial effects:
[0017] Install the dust screen to the position opposite to the condenser of the air conditioner. Because the infrared emitting source and the infrared receiver are both located on the same side of the mesh, and the transmitting port of the infrared emitting source and the receiving port of the infrared receiver are both facing the mesh, and the infrared receiver has the function of receiving the infrared light reflected by the mesh, so when the infrared light emitted by the infrared emitting source passes through the mesh without dust accumulation, the infrared receiver will not receive the infrared light. When the infrared light emitted by the infrared emitting source is reflected by the mesh with dust accumulation, the infrared receiver will receive the infrared light. And because the partition is located between the infrared emitting source and the infrared receiver, and there is a gap between the partition and the mesh, it is ensured that the infrared receiver can only receive the infrared light reflected from the mesh. Therefore, the dirt and blockage on the dust screen can be reflected by the infrared receiver's reception of infrared light.
[0018] That is to say, the dust screen can automatically and accurately detect the dirt and blockage conditions on the dust screen of the air conditioner. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0036] Figure 1 is a structural diagram of an air conditioner provided by an embodiment of the present disclosure, such as Figure 1 As shown, an embodiment of the present disclosure provides an air conditioner, which includes a dustproof net and a condenser 100. The condenser 100 is spaced apart from the dustproof net.
[0037] Since dust is easily accumulated at the condenser 100 of the air conditioner and thus affects the performance of the air conditioner, a dustproof net is installed at a position opposite to the condenser 100 to reduce dust falling onto the condenser 100 .
[0038] Figure 2 is a schematic diagram of the structure of a dustproof net provided in an embodiment of the present disclosure, Figure 2 The solid line with an arrow in the middle is infrared light, such as Figure 2 As shown, the embodiment of the present disclosure provides a dustproof net, which includes an infrared emitting source 10, an infrared receiver 20, a partition 30 and a net body 40. The infrared emitting source 10 and the infrared receiver 20 are both located on the same side of the net body 40, and the transmitting port of the infrared emitting source 10 and the receiving port of the infrared receiver 20 are both facing the net body 40. The partition 30 is located between the infrared emitting source 10 and the infrared receiver 20, and there is a gap 50 between the partition 30 and the net body 40. The infrared receiver 20 is configured to receive infrared light reflected by the net body 40.
[0039] Install the dustproof net to the position opposite to the condenser 100 of the air conditioner. Because the infrared emitting source 10 and the infrared receiver 20 are both located on the same side of the net body 40, and the transmitting port of the infrared emitting source 10 and the receiving port of the infrared receiver 20 are both facing the net body 40, and the infrared receiver 20 has the function of receiving the infrared light reflected by the net body 40, so first refer to Figure 2 , Figure 2 The solid line with an arrow in the middle is infrared light. When the mesh 40 is not clogged or the degree of clogs is very small, the infrared light emitted by the infrared emitting source 10 passes through the mesh 40, and the infrared receiver 20 does not receive the infrared light, indicating that the mesh 40 is not clogged and does not need to be cleaned. Figure 3 is a schematic diagram of the structure of a dustproof net provided in an embodiment of the present disclosure, Figure 3 The solid line with an arrow is infrared light, see Figure 3 When the dust on the mesh 40 accumulates to a certain extent, the mesh 40 is clogged to a large extent, and the infrared light emitted by the infrared emitting source 10 will be reflected by the dirty and clogged mesh 40, and the infrared receiver 20 will receive the infrared light, thereby detecting that the mesh 40 is clogged and the dust on the mesh 40 has accumulated to a degree that needs to be cleaned. In addition, since the partition 30 is located between the infrared emitting source 10 and the infrared receiver 20, and there is a gap 50 between the partition 30 and the mesh 40, it is ensured that the infrared receiver 20 can only receive the infrared light reflected from the mesh 40. Therefore, the dirt and blockage on the dustproof net can be reflected by the infrared receiver 20 receiving the infrared light.
[0040] That is to say, the dust screen can automatically and accurately detect the dirt and blockage conditions on the dust screen of the air conditioner.
[0041] See also Figure 2 In this embodiment, the orthographic projections of the infrared emitting source 10 and the infrared receiver 20 on the plane where the partition 30 is located are both located inside the partition 30 .
[0042] Because the orthographic projections of the infrared emitting source 10 and the infrared receiver 20 on the plane where the partition 30 is located are both located inside the partition 30, the partition 30 completely separates the infrared emitting source 10 and the infrared receiver 20 from the middle, so that the infrared light emitted from the infrared emitting source 10 cannot be directly received by the infrared receiver 20. The infrared receiver 20 can only receive the infrared light reflected from the dusty mesh 40, thereby improving the detection accuracy of the dustproof net for dirt and blockage.
[0043] In this embodiment, the dustproof net further includes a connecting body 60. The infrared emitting source 10 and the infrared receiver 20 are both connected to the same surface of the connecting body 60.
[0044] Because the dustproof net has a connector 60, the infrared emitting source 10 and the infrared receiver 20 can be connected together and spaced apart from each other on the same surface of the connector 60 to form an integrated structure, so that the installation of the infrared emitting source 10 and the infrared receiver 20 becomes more stable, and the installation position between the infrared emitting source 10 and the infrared receiver 20 is also more precise.
[0045] For example, see Figure 3 The connecting body 60 is a plate-shaped structural member, the infrared emitting source 10 and the infrared receiver 20 are both installed on the same surface of the connecting body 60, and the distance between the infrared emitting source 10 and the infrared receiver 20 is adjusted so that the infrared light emitted by the infrared emitting source 10 can be directly incident on the receiving end of the infrared receiver 20 after being reflected by the mesh body 40.
[0046] For example, see Figure 2 The partition 30 is located in the middle of the connecting plate, and a plane on the connecting body 60 that is connected to the infrared emitting source 10 and the infrared receiver 20 is also connected to the partition 30. The partition 30 is vertically connected to the connecting body 60 and is located right in the middle of the infrared emitting source 10 and the infrared receiver 20.
[0047] See also Figure 3 In this embodiment, the side of the connector 60 connected to the infrared emitting source 10 is parallel to the mesh body 40 .
[0048] Because the side of the connector 60 connected to the infrared emitting source 10 is parallel to the mesh 40, it can be avoided that the infrared light emitted by the infrared emitting source 10 cannot be reflected at the position of the infrared receiver 20 due to a large reflection angle with the mesh 40. The influence of the reflection angle on the detection of dirt and blockage on the mesh 40 can be reduced.
[0049] In this embodiment, the dustproof net further includes a mounting bracket 70 , one end of the mounting bracket 70 is connected to the connector 60 , and the other end of the mounting bracket 70 is connected to the net body 40 .
[0050] Because one end of the mounting bracket 70 is connected to the connector 60 and the other end is connected to the net body 40, and the connector 60 is connected to the partition 30, the infrared emitting source 10 and the infrared receiver 20, the internal parts of the dustproof net form a whole, which is easy for operators to install and disassemble conveniently and efficiently when using it.
[0051] For example, see Figure 2 There are two mounting brackets 70, and the two mounting brackets 70 are arranged flush with each other and spaced apart from each other. The connecting body 60 is located between the two mounting brackets 70, and one end of the first mounting bracket 70 and one end of the second mounting bracket 70 are connected to the same surface of the net body 40, and the other end of the first mounting bracket 70 is connected to one surface of the connecting body 60, and the other end of the second mounting bracket 70 is connected to the other surface of the connecting body 60, so that the connecting body 60 and the net body 40 are connected and fixed, and will not interfere with the infrared emitting source 10 on the connecting body 60 to emit infrared rays or the infrared receiver 20 to receive infrared rays.
[0052] In this embodiment, see Figure 1 The dustproof net further includes a controller 80 , which is electrically connected to the infrared emitting source 10 and the infrared receiver 20 , respectively.
[0053] Because the controller 80 is electrically connected to the infrared emitting source 10 and the infrared receiver 20 respectively, the controller 80 can be used to control the emission frequency of the infrared emitting source 10 and the sensitivity of the infrared receiver 20 to receiving infrared light.
[0054] For example, the controller 80 is used to adjust the emission frequency of the infrared emission source 10 to once every ten minutes, so that the dirt and blockage of the net body 40 can be detected once every ten minutes. In an environment with low dust, the controller 80 can be used to reduce the sensitivity of the infrared receiver 20 to infrared light to avoid misdetection. Or in an environment with high dust, the controller 80 can be used to enhance the sensitivity of the infrared receiver 20 to infrared light to reduce the impact of dust in the environment on the infrared receiver 20's function of receiving infrared light.
[0055] In this embodiment, see Figure 2 The dustproof net also includes a warning light 90. The warning light 90 is located on a side of the net body 40 away from the infrared emitting source 10. The warning light 90 is electrically connected to the controller 80.
[0056] Because the warning light 90 is electrically connected to the controller 80, when the infrared receiver 20 receives the infrared light reflected by the dusty net 40, the controller 80 can be used to convert the received infrared light signal into a light signal, and transmit the light signal to the warning light 90, and the warning light 90 will then light up to remind the operator that the dustproof net has been clogged and needs to be cleaned. In addition, because the warning light 90 is located on the side of the net 40 away from the infrared emission source 10, when the warning light 90 is on, the operator can see it more clearly, and will not be blocked by the net 40 and dust because it is located on the inner side of the net 40.
[0057] For example, see Figure 1 The controller 80 is installed on the same surface of the air conditioner connected to the dustproof net, which is convenient for operators to operate and view.
[0058] In this embodiment, see Figure 1 The air conditioner includes a mounting strip 200, and the mounting strip 200 is detachably connected to the edge of the dustproof net.
[0059] Because the dust screen and the air conditioner can be detachably connected via the mounting strip 200, the efficiency of mounting and replacing the dust screen is improved.
[0060] The above description is only an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the protection scope of the present disclosure.
