Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a maintenance auxiliary device for a combined air conditioner and the combined air conditioner. Background Art

[0002] Air conditioners are used to regulate indoor air, including adjusting the temperature, humidity, and air quality of the air, humidifying and dehumidifying the indoor air, introducing fresh air, etc. Air conditioners consist of a vapor compression refrigeration cycle system consisting of an evaporator, condenser, compressor, throttling device, and other necessary components. The air conditioner outputs cold / hot air through a fan to achieve cooling and heating of the indoor environment.

[0003] Combined air conditioner is an air conditioning system that integrates multiple air conditioning functions. Combined air conditioner is usually composed of multiple functional sections such as air filter, surface cooler, heater, humidifier, dehumidifier, fan, controller, etc. Different functional sections can be selected according to actual needs to meet different air conditioning needs.

[0004] Combined air conditioning units are characterized by high efficiency and energy saving, diverse functions, stable operation and easy operation. Combined air conditioning units adopt advanced energy-saving technologies, such as frequency conversion control, intelligent adjustment, etc., which can automatically adjust the operating status according to the actual load, thereby achieving high efficiency and energy saving. Combined air conditioning units integrate a variety of air conditioning functions and can be combined as needed to meet the air conditioning needs of different places. Combined air conditioning units use high-quality components and materials, and undergo strict production processes and quality control to ensure stable and reliable operation of the units. Combined air conditioning units adopt intelligent control systems, which can realize automatic control and remote monitoring, and are easy and convenient to operate.

[0005] However, during the use of combined air conditioners, their operating status needs to be monitored, and sometimes their internal parts need to be inspected. Most of the existing technologies are to set transparent observation windows on the door body of the relevant functional section, so that the operator can observe the internal operating status of the functional section with the naked eye, but this method cannot observe many key details, such as the bearing status. Increasing the size of the observation window is only a temporary solution. If more detailed parts need to be observed, even increasing the size of the observation window will not help.

In addition, the images captured by the camera module are clearer and of higher quality, and can also capture internal details that are difficult to observe with the naked eye, making it easier to monitor the operating status of the combined air conditioner in a timely and effective manner. In addition, maintenance personnel can also store the captured images for subsequent research and analysis.

[0037] Furthermore, in the maintenance auxiliary device of the combined air conditioner of the utility model, each lighting module is particularly arranged on the internal top wall of the functional section, and each observation window is located in the middle and lower part of the functional section in the vertical direction, so that the observation window and the lighting module have a certain distance, avoiding light directly shining on the observation window, which is not conducive to observation by maintenance personnel.

[0038] Furthermore, the maintenance auxiliary device of the combined air conditioner of the utility model further comprises a plurality of sensing modules, each functional segment provided with a camera module is provided with a sensing module, and the sensing module is used to detect obstacle signals within a preset range around the functional segment. The control module is electrically connected to the sensing module, and is used to receive obstacle signals, and when an obstacle signal sent by a sensing module is received, the camera module and the lighting module of the functional segment where the sensing module is located are turned on, and the image signal of the camera module is received.

The sensing module detects the obstacle signal and transmits it to the control module. The control module then controls the corresponding camera module to turn on and transmits the graphics to the mobile terminal so that the user can observe it in time.

[0040] In addition, the control module controls the lighting module to turn on at the same time, so that the user can observe the internal condition of the functional section through the observation window. When the maintenance of the functional section is completed, the maintenance personnel go to the next functional section, and the next functional section performs the same control process. This greatly improves the automation of the maintenance process and improves the maintenance efficiency.

[0053] On the one hand, an embodiment of the utility model provides a maintenance auxiliary device for a combined air conditioner.

[0054] Combined air conditioner is an air conditioning system that integrates multiple air conditioning functions. Combined air conditioner is usually composed of multiple functional sections such as air filter, surface cooler, heater, humidifier, dehumidifier, fan, control panel, etc. Different functional sections can be selected according to actual needs to meet different air conditioning needs.

[0055] The function of the maintenance auxiliary device of the combined air conditioner is to assist the maintenance personnel to carry out maintenance on the combined air conditioner, so as to timely control the operating status of the combined air conditioner, timely discover the operating failure of the combined air conditioner and carry out timely repairs, so that the combined air conditioner can operate normally.

[0056] Figure 1 is a schematic front view of a combined air conditioner 100 according to an embodiment of the utility model; Figure 2 It is a schematic block diagram of a maintenance auxiliary device 200 for a combined air conditioner 100 according to an embodiment of the utility model.

[0057] The combined air conditioner 100 of the embodiment of the present invention includes multiple functional sections.

[0058] Figure 1 A functional segment combination scheme of a combined air conditioner 100 is illustrated. In the combined air conditioner 100 , multiple functional segments include an air intake segment 110 , a primary filter segment 120 , an electronic purification segment 130 , a surface cooling segment 140 and an air supply segment 150 .

[0059] The air inlet section 110 is used to inhale air to form an inlet airflow. The primary filter section 120 is arranged downstream of the air inlet section 110, and is used to filter the airflow. The electronic purification section 130 is arranged downstream of the primary filter section 120, and is used to sterilize the airflow. The surface cooling section 140 is arranged downstream of the electronic purification section 130, and is used to heat or cool the airflow. The air supply section 150 is arranged downstream of the surface cooling section 140, and is used to supply the airflow to the indoor environment. The specific working principle and structural design of each functional section are well known to those skilled in the art and will not be repeated here.

[0060] Of course, the combined air conditioner 100 may also include other functional segments and adopt other combinations, which are not limited in the embodiment of the present utility model.

[0061] Please refer to Figure 1 and Figure 2 As shown, the maintenance auxiliary device 200 for the combined air conditioner 100 according to the embodiment of the utility model may generally include a plurality of camera modules 230 , a control module 280 and a communication module 250 .

[0062] Among the multiple camera modules 230, each camera module 230 is set in a functional segment and is used to take a picture of the corresponding functional segment. Each camera module 230 may include a camera, and the camera takes a picture of the part that needs to be monitored in the functional segment, such as a key bearing part. Of course, each camera module 230 may also include multiple cameras, each camera is used to take a picture of a key part of the functional segment.

[0063] The control module 280 is electrically connected to the plurality of camera modules 230 and is used to control the operating state of each camera module 230 , specifically, including controlling the on / off and other operating states of the camera module 230 . The control module 280 is also used to receive image signals transmitted by each camera module 230 .

[0064] The communication module 250 is electrically connected to the control module 280 and the mobile terminal 300, and is used to transmit the image signal received by the control module 280 to the mobile terminal 300 for display, forming a video or picture image.

[0065] The communication module 250 may be a Bluetooth module, a WiFi module, a NB communication module, a ZigBee communication module, etc. The mobile terminal 300 may be a mobile phone, a tablet computer, a notebook computer, or other device capable of displaying images.

[0066] The maintenance auxiliary device 200 for the combined air conditioner 100 of the embodiment of the utility model is capable of photographing the inside of the functional section and displaying the image on the mobile terminal 300 due to the provision of the camera module 230, the control module 280 and the communication module 250. The maintenance personnel can judge the operating status of the inside of the functional section through the image received by the mobile terminal 300, without the need to use the observation window, open the door, or shut down the air conditioner, which is more convenient, quicker and provides a better experience.

[0067] Moreover, the images captured by the camera module 230 are not only clear, but also can capture the internal details that are difficult to observe with the naked eye, so that maintenance personnel can timely and effectively monitor the operating status of the combined air conditioner 100. Moreover, the captured images can be stored for subsequent research and analysis, which greatly facilitates maintenance personnel.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the maintenance auxiliary device 200 also includes a plurality of lighting modules 220. Each lighting module 220 is arranged in a functional section for illuminating the interior of the functional section. Each lighting module 220 may include a lamp or a group of lamps. The lamps in a group of lamps are dispersedly arranged to illuminate different parts. After the lighting module 220 is turned on, the interior of the functional section remains bright, which, on the one hand, makes the shooting effect of the camera module 230 better, and on the other hand, is convenient for maintenance personnel to observe with the naked eye.

[0069] Further, in some embodiments of the present invention, Figure 1 and Figure 2 As shown, at least some functional sections include observation windows, for example, the air intake section 110, the electronic purification section 130 and the air supply section 150 are respectively provided with observation windows 1120, 1320, 1520, so that maintenance personnel can observe the internal conditions of the functional sections from the outside of the functional sections. The observation windows 1120, 1320, 1520 can be open windows, or can be installed with transparent sealing parts such as glass. For some functional sections that do not require daily maintenance, such as the primary filter section 120 and the surface cooling section 140, no observation windows may be provided.

[0070] like Figure 1 As shown, the observation windows 1120, 1320, 1520 can be installed on the door bodies 112, 132, 152 of the corresponding functional sections. Figure 1 For the sake of clarity, the lighting module 220 and the camera module 230 originally located inside the functional segment are exposed.

[0071] Each lighting module 220 may be further staggered with the observation windows 1120, 1320, 1520 in the vertical direction to prevent light from directly irradiating the observation windows 1120, 1320, 1520 and hindering the maintenance personnel from observing. Figure 1 As shown, each lighting module 220 can be arranged on the inner top wall of the functional segment, and each observation window 1120 , 1320 , 1520 is located at the middle and lower part of the functional segment in the vertical direction so as to be staggered with the lighting module 220 .

[0072] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the maintenance auxiliary device 200 further includes a plurality of sensing modules 210 .

[0073] Each functional segment provided with a camera module 230 is equipped with a sensing module 210, which is used to detect obstacle signals within a preset range around the functional segment. Each sensing module 210 can be arranged outside the functional segment, specifically, each sensing module 210 is arranged on the door body 112, 132, 152 of the corresponding functional segment.

[0074] Each sensing module 210 may be an infrared sensing module. The preset range may be a range less than m from the sensing module 210, where m may be 0.5 m, 1 m, etc., and may be reasonably set by a technician. When a maintenance worker appears within the preset range, the sensing module 210 determines that the maintenance worker is an obstacle and sends an obstacle signal.

[0075] The control module 280 is electrically connected to each sensing module 210 and each lighting module 220 for receiving obstacle signals and, upon receiving an obstacle signal from a sensing module 210, turning on the camera module 230 and the lighting module 220 of the functional segment where the sensing module 210 is located and receiving the image signal of the camera module 230.

[0076] In this way, when the maintenance personnel inspect a certain functional section, they walk to the side of the functional section and enter the detection range of the sensing module 210 of the functional section. The sensing module 210 detects the obstacle signal and transmits it to the control module 280. The control module 280 then controls the corresponding camera module 230 to turn on and transmits the graphics to the mobile terminal 300 so that the user can observe it in time.

[0077] In addition, the control module 280 controls the lighting module 220 to turn on at the same time, so that the user can observe the internal conditions of the functional section through the observation windows 1120, 1320, and 1520. When the maintenance of the functional section is completed, the maintenance personnel go to the next functional section, and the next functional section performs the same control process. This greatly improves the automation of the maintenance process and improves the maintenance efficiency.

[0078] In some embodiments of the present invention, each camera module 230 includes at least one camera whose direction can be adjusted remotely. In this way, the maintenance personnel can control the direction of the camera through the control module 280 and point it to a desired angle. Furthermore, the mobile terminal 300 can be installed with a preset control software, and the user can view the image and adjust the direction of the camera through the software.

[0079] In some embodiments, the camera of each camera module 230 may be a camera with a light, so as to shoot in the dark inside the functional segment to achieve better image effect.
