Description

Technical Field

[0002] At present, the electrical box can be widely used as a part of the motor in household appliances such as air conditioners to control the work of the motor. The assembly method adopted by the electrical boxes on the market is to screw the controller such as the PCB board in the electrical box into the aluminum box first by screwing and then filling the sealant to seal it. However, if the address of the controller needs to be set, the sealant in the electrical box needs to be cleaned and the screws need to be unscrewed before the controller can be set. For the staff who implement these steps, it will undoubtedly increase the complexity and difficulty of operation. In addition, removing the controller from the electrical box will easily cause hardware damage to the controller and increase the production cost of the motor controlled by the controller and including the electrical box. In addition, the specific method of the existing address setting is also relatively complicated, and multiple single buttons need to be operated. In addition, after the controller is installed in the electrical box, the sealant is used to make the controller completely sealed in the electrical box. When the motor is abnormal, the running state of the controller cannot be observed and detected, which is not conducive to optimizing the motor. In addition, the existing motor needs to control its controller to receive control from the host computer. When there is no host computer, the motor has the problem of being unable to run by itself.

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] refer to Figures 1 to 8As an object of the present invention, an embodiment of the present invention provides an electrical box assembly, which includes an electrical box housing, a box body 1 and an end cover 3 that cooperates with the box body 1 in a waterproof manner. The box body is a thin shell type, and a hollow cavity is formed inside the box body 1. A PCB board 4 for electrically connecting to a motor is provided in the cavity. It can be understood that the motor includes a motor body and an electrical box assembly, and the electrical box assembly can be arranged on the motor, and the motor of the motor body is electrically connected to the PCB board 4, so that the PCB board 4 controls the winding power-on logic in the motor so that the motor runs according to various predetermined parameters and the PCB board 4 can also obtain the running status information of the motor, and the motor can be used in different occasions according to actual needs. The end cover 3 is detachably covered on the opening of the cavity to enclose the PCB board 4 therein. The box body 1 is provided with a light-transmitting portion 11 consisting of a through hole. It should be noted that the above-mentioned opening, through hole and light-transmitting portion can substantially refer to the same component. The corresponding part of the box body 1 where the light-transmitting portion 11 is provided has a certain thickness, that is, the through hole constituting the light-transmitting portion 11 has a certain hole depth and aperture, so as to ensure that the boss 31, the communication port circuit, the dial switch and the button can be accommodated, and can be manually operated or external components can be plugged in and out (further described below). The communication port circuit is provided at the bottom of the PCB board 4, and the light-transmitting portion 11 is used to display the information of the communication port circuit. The bottom of the PCB board 4 is provided with a dial switch, and the light-transmitting portion 11 allows the dial switch 43 to be directly operated without disassembling the motor. A button 44 is provided at the bottom of the PCB board 4, so that when there is no upper computer to control the motor, the light-transmitting portion 11 allows the button 44 and the dial switch 43 to be combined and operated to perform the local operation mode and directly drive the operation. Therefore, since the light-transmitting portion 11 of the box body 1 is sealed by means of a detachable waterproof cover of the end cover 3, the light-transmitting portion 11 can be sealed and opened by installing and removing the end cover 3, thereby avoiding the unfavorable situation that the disassembly and assembly are complicated and easy to cause hardware damage caused by the use of sealant to seal the existing electrical box. In addition, after the end cover 3 is removed and the light-transmitting portion 11 is opened, the communication port circuit, the dip switch 43 and the button 44 on the PCB board 4 can be observed and / or operated through the light-transmitting portion 11. In this way, without removing the end cover 3 relative to the box body, the user can conveniently achieve the desired purposes of conveniently setting the address, easily observing the motor operation status, and being able to locally control the motor operation.

[0034] Key References Figure 1 and Figure 3Specifically, a circle of grooves 12 is provided on the box body 1, and the circle of grooves 12 is arranged on the end face of the box body 1 relative to the light-transmitting portion 11 and away from the PCB board 4. For example, preferably, a circle of circular grooves 12 is provided on the circumference of the box body 1 around the light-transmitting portion 11, and the size of the circular groove 12 is set to: diameter: 2mm and depth: 2mm. The electrical box assembly also includes a sealing ring 2 arranged in the groove 12. The sealing ring 2 adopts a waterproof rubber ring and has a diameter set to: 39mm. The diameter of the above-mentioned light-transmitting portion 11 is set to: 36mm, so that the sealing ring 2 is compressed and assembled in the groove 12. A plurality of first buckles 13 are provided on the inner peripheral wall of the light-transmitting portion 11, and the end cover 3 includes a boss 31 for being inserted into the light-transmitting portion 11, and a plurality of second buckles 33 which can be detachably engaged with the plurality of first buckles 13 are provided on the outer peripheral wall of the boss 31. Therefore, the end cover 3 can be conveniently engaged with and separated from the box body by means of buckles, thereby ensuring excellent waterproof performance while facilitating corresponding observation and operation through the light-transmitting portion.

[0035] Key References Figure 1 and Figure 3 Specifically, the end cover 3 also includes a flange 32 surrounding the outer periphery of the boss 31. When the end cover 3 rotates relative to the light-transmitting portion 11 along the engagement direction, the first buckle 13 and the second buckle 33 are engaged. When the end cover 3 rotates relative to the light-transmitting portion 11 along the separation direction, the first buckle 13 and the second buckle 33 are separated. In addition, a hand grip that is easy to rotate is provided on the side of the end cover 3 facing away from the light-transmitting portion 11. In this way, the end cover can be opened or closed by the rotation direction, and the operation is convenient and quick.

[0036] Preferably, four first buckles 13 and second buckles 33 are provided, that is, the end cover 3 realizes a buckle connection and compresses the sealing ring 2 in each 90° area of ​​the 360° circumference of the light-transmitting portion 11, thereby ensuring that the end cover 3 is sealed and fixed to the light-transmitting portion 11 at equal angles, ensuring that the electrical box has excellent sealing performance, and each first buckle 13 is provided as a protrusion arranged at equal intervals along the same circumference of the inner circumferential wall, and the rectangular size of each protrusion can be set to: length * width * height = 8mm * 1.5mm * 1.5mm, and four notches 34 for each protrusion to enter are provided at one end of the outer circumferential wall away from the flange 32, and four notches 34 are provided on the outer circumferential wall at equal intervals along the buckling direction A second clip 33 and a stop block 35 are provided at a position away from each notch 34, and four are provided on the outer peripheral wall. Each second clip 33 is arranged at equal intervals along the same circumference of the outer peripheral wall, and each second clip 33 is arranged as an arc-shaped protrusion, and the height of each arc-shaped protrusion relative to the flange 32 gradually increases along the buckling rotation direction, and each arc-shaped protrusion slides along each corresponding protrusion until the protrusion abuts against the stop block 35, and the flange 32 abuts against the outer periphery of the light-transmitting portion 11 so that the sealing ring 2 is elastically deformed and compressed in the groove 12, so that the volume of the sealing ring 2 is compressed by about 25%, thereby tightly closing the groove 12, the end cover 3 and the sealing ring 2. Therefore, when the end cover 3 is tightened by the user along the snap-fit ​​rotation direction, each protrusion correspondingly guides each arc-shaped protrusion to rotate and slide along the radial direction of the light-transmitting portion 11 while also moving toward the box body along the axial direction, thereby applying sufficient axial force to make the flange 32 and the sealing ring 2 tightly connected to achieve a good waterproof and dustproof sealing effect, thereby ensuring that the motor meets the dustproof and waterproof capabilities of IP67.

[0037] Key References Figure 5 and Figure 8 Preferably, the communication port circuit includes a needle holder 41 and an indicator light 42. The needle holder 41 is a type of external terminal. The external terminal includes the needle holder 41, a wiring terminal, etc., and its specific function is to realize functions such as program communication burning into the processor, i.e. communication downloading, etc. The PCB board 4 includes a communication interface module. It should be understood that the communication interface module and the following modules are all arranged on the PCB board 4, such as a processor of a main control chip CPU, PLC, single-chip microcomputer, etc., so as to realize corresponding communication, control and other functions. For example, for the communication interface module, it has a communication port circuit and belongs to the peripheral hardware circuit of the motor. The communication port circuit can complete specific hardware functions and can realize program communication and burn it into the processor on the PCB board 4. The needle seat 41 is electrically connected to the communication interface module. The communication interface module receives information transmitted by an external component plugged into the needle seat 41 to update the program of the controller. The external component can be a laptop, a U disk, etc. Therefore, by communicating with the communication interface module through the external component plugged into the needle seat 41 through the light-transmitting portion 11, the controller program can be updated and the data of the motor's operating status information such as speed, power, current, and voltage can be read.

[0038] Specifically, the indication output is the number of times the indicator light 42 flashes. The operating status information includes that the indicator light 42 is electrically connected to the communication interface module. The communication interface module obtains the operating status information of the motor. The indicator light 42 performs different indication outputs according to different operating status information. The specific number of indicator lights 42, multi-color or single-color, constant light or flashing and other indication output methods can be adopted according to needs. Therefore, for example, when the motor fails, there is no need to disassemble the entire motor or the electrical box. You only need to open the end cover 3 to intuitively find the specific situation of the fault by observing the working status of the indicator light 42, which is convenient and quick.

[0039] The speed, power, current and / or voltage of the motor. Generally speaking, the running state of the motor is defined by a program and implemented in conjunction with the hardware circuit. The program for controlling the running state of the motor is burned and downloaded into the motor main control chip through the pin socket 41, which can also be called an external terminal. The pin socket 41 serves as a transmission adapter and is a bridge for communicating between the external program and the internal program of the motor. The communication interface module can determine the fault condition of the motor according to the running state information and control the flashing of the indicator light 42. In this embodiment, the indicator light 42 indicates the fault state of the motor by flashing. For example, the corresponding relationship between the number of flashes of the indicator light 42 and the fault state is set as follows: 1: The indicator light 42 flashes 2 times: DC bus overvoltage (exceeding 400V) protection; 2: The indicator light 42 flashes 3 times: DC bus undervoltage (lower than 170V) protection, 3: The indicator light 42 flashes 4 times: three-phase overcurrent protection, 4: The indicator light 42 flashes 5 times: power protection, 5: The indicator light 42 flashes Flashes 6 times: phase loss protection, 6: indicator light 42 flashes 7 times: FO hardware overcurrent protection, 7: indicator light 42 flashes 8 times: bias voltage error protection, 8: indicator light 42 flashes 9 times: stall protection, 9: indicator light 42 flashes 10 times: out-of-step protection, 10: indicator light 42 flashes continuously, i.e. countless times: the input frequency signal is out of range; therefore, the user can easily understand the operating status of the motor by observing the flashing status of the indicator light 42. More preferably, the end cover 3 is made of transparent material, so the working status of the indicator light 42 can be observed without opening the end cover 3, which is more convenient and quick.

[0040] Key References Figure 6 and Figure 8Preferably, the dip switch 43 includes a first switch 431 and a second switch 432, both of which have an on state and an off state. The PCB board 4 includes an address coding module electrically connected to the dip switch 43. The address coding module determines the address of the controller according to the switch information of the dip switch 43. The address of the controller is the address of the controller after the PCB board 4 is installed in the electrical box housing to form a whole. At this time, the address of the electrical box assembly is the address of the controller. When a single electrical box assembly is not equipped with the PCB board 4, the electrical box assembly belongs to a hardware structure and does not have a communication function, that is, it does not have a communication address. The address of the controller can be used to match the corresponding mode for communication. By toggling the first switch 431 and the second switch 432 to obtain different switch state combinations, it is determined that the controller has different addresses. In this embodiment, the two indicator lights 42 can be used to set four different addresses through the four different switch state combinations they have. For example, the corresponding relationship between the different switch state combinations of the two dial switches 43 and the specific addresses set is as follows: 1: When the first switch 431 and the second switch 432 are both in the OFF position, the controller is set to address 1; 2: When the first switch 431 is in ON and the second switch 432 is in OFF, the controller is set to address 2; 3: When the first switch 431 is in OFF and the second switch 432 is in ON, the controller is set to address 3; When the first switch 431 and the second switch 432 are both in ON, the controller is set to address 4. Therefore, when it is necessary to set the address of the controller, there is no need to disassemble the entire motor or electrical box. You only need to open the end cover 3 to set it by operating the dial switch 43, which greatly reduces the complexity and difficulty of operation. Moreover, the use of the dial switch 43 not only reduces the number of uses but also makes the setting relatively simple and quick.

[0041] Key References Figure 6 and Figure 8 The PCB board 4 also includes a local control module, which is electrically connected to the button 44 and the address coding module. The local control module directly controls the operation of the motor according to the local operation information received from the button 44 and the address coding module. Specifically, the combined control of the button 44 and the dial switch 43 can be implemented by the processor on the PCB board 4, so as to realize the local operation mode of the motor. Therefore, when the motor cannot run by itself due to the lack of a host computer, there is no need to disassemble the entire motor or the electrical box. You only need to open the end cover 3 and then operate the button 44 to directly drive the motor to run in the local operation mode to ensure the normal operation of the motor.

[0042] Key References Figure 7 and Figure 8Specifically, the button 44 includes a first button 441 and a second button 442. The first button 441, the second button 442, the first switch 431 and the second switch 432 are operated together to determine the local operation information for the local control module to receive. The different switch state combinations of the first switch 431 and the second switch 432 are used to determine the direction, speed and / or power of the motor. The first button 441 and the second button 442 are respectively used to determine the increase and decrease of the speed of the motor or to determine the start and pause of the motor. Therefore, on the basis of the first switch 431 and the second switch 432 playing the role of setting the address of the electrical box, the two switches can also work together with the two buttons to achieve the control of the local operation state of the motor. In this embodiment, In the embodiment, four different operation combinations of each switch and each button can control four different local operating states of the motor. For example, the corresponding relationship between the different operation combinations of each dial switch 43 and each button and the four different local operating states is as follows: 1: When the first switch 431 is in ON and the second switch 432 is in OFF, the motor is in forward mode, the first button controls acceleration, and the second button controls deceleration; 2: When the first switch 431 is in OFF and the second switch 432 is in ON, the motor is in reverse mode, the first button controls acceleration, and the second button controls deceleration; 3: When the first switch 431 and the second switch 432 are in ON at the same time, the motor is in maximum speed operation (that is, the system allows a maximum speed of 1500rpm), the first button controls start, and the second button controls pause; 4: When the first switch 431 and the second switch 432 are in OFF at the same time, the motor is in maximum power operation (that is, the system allows a maximum power of 1500W), button 1 controls start, and button 2 controls pause.

[0043] As another object of the present invention, another embodiment of the present invention provides an air conditioner, which includes a motor and any of the above electrical box assemblies, and the motor is electrically connected to the PCB board. Therefore, the air conditioner has any beneficial effects of the electrical box assembly, which will not be repeated here.
