[0028] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0029] The following is for reference. Figures 1-13 The description of the electrical control box 100 according to an embodiment of the present utility model is as follows: the electrical control box 100 can be applied to the indoor unit of an air conditioner.

[0030] Combination Figures 1-13 As shown, the electrical control box 100 according to this utility model can mainly include: a main body box 10, a device mounting box 20, a human sensing control board 30, and a display screen control board 40.

[0031] The electrical control box 100 contains a main control board 101, which is adapted to be electrically connected to the relevant electrical components in the air conditioner. The main control board 101 can send control commands to the relevant electrical components in the air conditioner and receive feedback signals or data information from these components in order to monitor and regulate the operating status of these components.

[0032] The electrical control box 100 includes a main body box 10 and a component mounting box 20. The main control board 101 is disposed in the main body box 10; the component mounting box 20 is disposed on one side of the main body box 10 and is an integrally formed structural component with the main body box 10, and multiple components are disposed on the component mounting box 20.

[0033] Specifically, the main control board 101 is installed inside the main box 10. The main box 10 not only provides the necessary installation space and mechanical support for the main control board 101 to ensure that the main control board 101 is installed firmly, but also effectively blocks external dust, moisture, oil and other impurities, preventing these impurities from adhering to the surface of the main control board 101. At the same time, the main box 10 can also prevent external physical impacts from directly acting on the main control board 101, thereby improving the stability and reliability of the main control board 101 during operation.

[0034] Furthermore, the component mounting box 20 is located on one side of the main body box 10. This allows the electrical control box 100 to be divided into areas by the main body box 10 and the component mounting box 20. If a fault occurs in the area where the component mounting box 20 is located, only the components or lines in the area of ​​the component mounting box 20 need to be replaced or repaired. If a fault occurs in the area of ​​the main body box 10, only the components and lines in the area of ​​the main body box 10 need to be replaced or repaired. This can reduce the maintenance difficulty and spare parts cost of the electrical control box 100.

[0035] Furthermore, the component mounting box 20 and the main body box 10 are integrally formed structural components. This eliminates the need for seams and connection points between the component mounting box 20 and the main body box 10, thereby improving the connection strength and stability between them and effectively preventing loosening or failure. It also enhances the relative positioning accuracy of the components between the component mounting box 20 and the main body box 10. Moreover, no connectors are required for the connection between the component mounting box 20 and the main body box 10, which simplifies the assembly process, improves assembly efficiency, reduces labor assembly costs, and reduces the number of components inside the control box 100, thus facilitating the lightweight design of the control box 100.

[0036] Furthermore, the device mounting box 20 is equipped with multiple devices, which allows the mounting structure for mounting each device to be integrated on the device mounting box 20. The relevant devices are then installed on the device mounting box 20, which facilitates the installation, debugging and maintenance of the relevant devices by the operators. This also helps with the expansion and troubleshooting of the electrical control box 100.

[0037] The electrical control box 100 also includes a human sensor control board 30 and a display screen control board 40. The human sensor control board 30 is disposed inside the device mounting box 20; the display screen control board 40 is snapped into the device mounting box 20, and the human sensor control board 30 and the display screen control board 40 are electrically connected to each other. One of the human sensor control board 30 and the display screen control board 40 is electrically connected to the main control board 101; a probe mounting boss 201 is provided on the front side of the device mounting box 20, and a human sensor probe 50 is snapped into the probe mounting boss 201 and electrically connected to the human sensor control board 30. The front side of the probe mounting boss 201 is open.

[0038] Specifically, both the human sensor control board 30 and the display screen control board 40 are snapped into the device mounting box 20. The device mounting box 20 not only provides physical protection for the human sensor control board 30 and the display screen control board 40, preventing external dust, moisture and other foreign objects from adhering to the human sensor control board 30 and the display screen control board 40, and preventing external physical impacts from directly acting on the human sensor control board 30, but also provides a relatively enclosed installation space for the human sensor control board 30 and the display screen control board 40, preventing the human sensor control board 30 and the display screen control board 40 from being exposed, and reducing the risk of electric shock to the electrical control box 100.

[0039] In addition, both the human sensor control board 30 and the display screen control board 40 are installed in the device mounting box 20 using a snap-fit ​​method. This not only makes the installation of the human sensor control board 30 and the display screen control board 40 simpler, more direct, and more stable and reliable, but also facilitates the installation and disassembly of the human sensor control board 30 and the display screen control board 40, making subsequent maintenance and replacement easier. Moreover, the entire installation process of the human sensor control board 30 and the display screen control board 40 does not require the use of screwdrivers or other tools, nor does it require precise alignment of multiple screw holes, which simplifies the installation difficulty of the human sensor control board 30 and the display screen control board 40 and improves installation efficiency.

[0040] Furthermore, the human sensor control board 30 and the display screen control board 40 are electrically connected to each other, and one of the human sensor control board 30 and the display screen control board 40 is electrically connected to the main control board 101. This not only allows the human sensor control board 30 and the display screen control board 40 to send and receive electrical signals to each other, but also allows the human sensor control board 30 to notify the display screen control board 40 through the electrical connection between the human sensor control board 30 and the display screen control board 40 to wake up the screen, turn on the backlight, or switch the display content, etc. It also simplifies the wiring layout in the function expansion box and avoids messy wiring in the function expansion box.

[0041] Furthermore, a probe mounting boss 201 is provided on the front side of the device mounting box 20. The human sensor probe 50 is snapped into the probe mounting boss 201. The probe mounting boss 201 not only provides protection for the human sensor probe 50, reducing the damage caused by external physical impacts to the human sensor probe 50, but also provides a snap-fit ​​mounting position for the human sensor probe 50 to be installed in the probe mounting boss 201. This not only makes the installation of the human sensor probe 50 simpler, more direct, more stable and reliable, but also facilitates the installation and removal of the human sensor probe 50, and facilitates the subsequent inspection and replacement of the human sensor probe 50.

[0042] Moreover, the entire installation process of the human sensor 50 does not require the use of tools such as screwdrivers, nor does it require precise alignment of multiple screw holes, which simplifies the installation difficulty of the human sensor 50 and improves installation efficiency.

[0043] Furthermore, the human sensor 50 is electrically connected to the human sensor control board 30, so that the human information sensed by the human sensor 50 can be transmitted to the human sensor control board 30, which processes and outputs the received information. The front of the sensor mounting boss 201 is open, so that the front of the human sensor 50 is not obstructed, so that the human sensor 50 can detect human information in the surrounding environment.

[0044] Thus, by placing the human sensor 50 inside the sensor mounting protrusion 201 on the front side of the device mounting box 20, the human sensor control board 30 and the display control board 40 inside the device mounting box 20, and the display screen on the front side of the indoor unit of the air conditioner, the human sensor 50 and the human sensor control board 30 are placed separately, and the display screen and the display control board 40 are placed separately. This reduces the total volume occupied by the human sensor 50, the human sensor control board 30, the display screen and the display control board 40, and improves the structural compactness and space utilization of the indoor unit of the air conditioner.

[0045] Furthermore, by integrating mounting structures for mounting various components onto the component mounting box 20, the human detection control board 30, display control board 40, and human detection probe 50 can be directly mounted on their respective mounting structures. This allows for the installation of each component within the component mounting box 20, eliminating the need for additional mounting structures, simplifying the assembly process, reducing installation difficulty, and improving assembly efficiency. It also reduces the assembly gaps between components. Additionally, this improves the mounting accuracy of components on the electrical control box 100.

[0046] In some embodiments of this utility model, combined with Figure 5 , Figure 6 , Figure 9 and Figure 11As shown, a first positioning part 2011 and a first locking part 2012 are respectively provided on the left and right sides of the probe mounting boss 201. A second positioning part 501 and a second locking part 502 are respectively provided on the left and right sides of the human sensor probe 50. One of the first positioning part 2011 and the second positioning part 501 is a positioning protrusion and the other is a positioning groove. The positioning groove and the positioning protrusion are positioned and engaged. One of the first locking part 2012 and the second locking part 502 is a first buckle and the other is a first slot. The first buckle and the first slot are engaged and engaged.

[0047] Thus, the engagement of the first latch and the first slot not only ensures a simple, direct, and reliable connection between the probe mounting boss 201 and the human sensor probe 50, preventing the human sensor probe 50 from loosening or detaching from the probe mounting boss 201, but also facilitates the installation and removal of the human sensor probe 50, as well as its maintenance and replacement. The positioning engagement of the positioning protrusion and the positioning groove allows for quick determination of the human sensor probe 50's position on the mounting boss, improving installation efficiency and accuracy.

[0048] Moreover, the entire installation process of the human sensor 50 does not require the use of tools such as screwdrivers, nor does it require precise alignment of multiple screw holes, which simplifies the installation difficulty of the human sensor 50 and improves installation efficiency.

[0049] In other embodiments of this utility model, combined with Figure 5 , Figure 6 , Figure 9 and Figure 11 As shown, a probe mounting cover is provided on the front side of the probe mounting boss 201. The human sensor 50 is disposed between the probe mounting boss 201 and the probe mounting cover, and the portion of the probe mounting cover corresponding to the human sensor 50 is open to facilitate the human sensor 50 in detecting human information in the environment. The open portion of the probe mounting cover corresponding to the human sensor 50 includes, but is not limited to, a circular hole.

[0050] Furthermore, a first positioning part 2011 and a first snap-fit ​​part 2012 are respectively provided on the left and right sides of the probe mounting boss 201, and a second positioning part 501 and a second snap-fit ​​part 502 are respectively provided on the left and right sides of the probe mounting cover. One of the first positioning part 2011 and the second positioning part 501 is a positioning protrusion, and the other is a positioning groove. The positioning groove and the positioning protrusion are positioned and engaged. One of the first snap-fit ​​part 2012 and the second snap-fit ​​part 502 is a first buckle, and the other is a first slot. The first buckle and the first slot are engaged and engaged.

[0051] Thus, the engagement of the first buckle and the first slot not only ensures a simple, direct, and reliable connection between the probe mounting boss 201 and the probe mounting cover, preventing the probe mounting cover from loosening or detaching from the probe mounting boss 201, but also facilitates the fixed installation of the human sensor 50. Furthermore, the probe mounting cover facilitates the installation and removal of the human sensor 50, and consequently, the inspection and replacement of the human sensor 50. The positioning engagement of the positioning protrusion and the positioning groove allows for quick determination of the probe mounting cover's position on the probe mounting boss 201, improving the installation accuracy and efficiency of the probe mounting cover.

[0052] Combination Figure 1 and Figure 6 As shown, a plane extending in the up-down direction and perpendicular to the front-back direction is defined as a vertical plane. The human sensor 50 is tilted downwards and forwards relative to the vertical plane, forming an angle α with the vertical plane. α satisfies the relationship: 20°≤α≤30°.

[0053] Specifically, if the angle between the human sensor 50 and the vertical plane is less than 20°, the detection range of the human sensor 50 will be concentrated in a small area directly below and very close to the human sensor 50. This will shorten the detection distance of the human sensor 50, which may result in the human sensor 50 being unable to detect human information beyond a certain distance, causing a missed alarm.

[0054] If the angle between the human sensor 50 and the vertical plane is greater than 30°, the human sensor 50 may detect walls or even ceilings further away, resulting in a reduced detection area on the ground near the human sensor 50. This may lead to the human sensor 50 failing to detect human information within a certain distance, causing false alarms. In addition, the human sensor 50 is tilted upwards, making it susceptible to interference from heat sources or flying insects on the ceiling, causing false alarms.

[0055] Therefore, the angle between the human sensor 50 and the vertical plane should be no less than 20° and no more than 30°. This allows the human sensor 50 to effectively cover the activity area that needs to be detected, making the detection range of the human sensor 50 more suitable for the actual environment, reducing or avoiding missed and false alarms of the human sensor 50, and improving the accuracy and effectiveness of the detection results of the human sensor 50.

[0056] In some specific embodiments of this utility model, preferably, the included angle between the human sensor 50 and the vertical plane is 25°.

[0057] Combination Figure 4 , Figure 7 and Figure 13As shown, both the human sensor control board 30 and the display screen control board 40 extend in the front-to-back direction and are arranged perpendicularly to each other. Specifically, by extending both the human sensor control board 30 and the display screen control board 40 in the front-to-back direction and arranging them perpendicularly to each other, not only can the overall space occupied by the human sensor control board 30 and the display screen control board 40 in the front-to-back direction be reduced, improving the structural compactness and space utilization within the electrical control box 100, optimizing the shape of the electrical control box 100 and the spatial layout within the electrical control box 100, but it also helps to shorten the electrical connection lines between the human sensor control board 30 and the display screen control board 40, and shorten the signal transmission distance between the human sensor control board 30 and the display screen control board 40.

[0058] Combination Figure 2 , Figure 4 , Figure 7 and Figure 13 As shown, the device mounting box 20 is provided with a first snap-fit ​​mounting slot 202 and a second snap-fit ​​mounting slot 203. The human sensor control board 30 is snap-fitted into the first snap-fit ​​mounting slot 202, and the display screen control board 40 is snap-fitted into the second snap-fit ​​mounting slot 203.

[0059] Thus, by snapping the human sensor control board 30 into the first snap-fit ​​mounting slot 202 and the display screen control board 40 into the second snap-fit ​​mounting slot 203, the installation of the human sensor control board 30 and the display screen control board 40 becomes simple, direct, stable, and reliable, preventing them from loosening. It also facilitates the installation and removal of the human sensor control board 30 and the display screen control board 40, making inspection and replacement easier. Furthermore, the snap-fit ​​installation process eliminates the need for screwdrivers or other tools, and eliminates the need for precise alignment of multiple screw holes, simplifying the installation process and improving efficiency.

[0060] In some embodiments of this utility model, an elastic buckle is provided on one side of the device mounting box 20 in the front-to-back direction, and a limiting block is provided on the other side. The human sensor control board 30 and the display control board 40 are limited and engaged with the limiting block on one side in the front-to-back direction, and elastically engaged with the elastic buckle on the other side. Thus, the human sensor control board 30 and the display control board 40 are fixedly installed through the combined action of the limiting block and the elastic buckle.

[0061] Combination Figure 1 , Figure 3 and Figure 7 As shown, the device mounting box 20 includes: a box body 204, a first cover 205, and a second cover 206.

[0062] Specifically, one side of the box 204 in the left-right direction is opened to form a first open side 2041, and one side of the box 204 in the up-down direction is opened to form a second open side 2042. This facilitates the installation and removal of the control board and devices inside the box 204.

[0063] Furthermore, the first cover 205 is placed over the first open side 2041, and the human sensor control board 30 is disposed opposite to the first cover 205.
