[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0028] According to an embodiment of the present utility model, a compressor protection module is provided. Please refer to Figures 1 to 4 , including: a basic module 10, the basic module 10 is provided with a basic detection device 1 and a main chip 2 signal-connected to the basic detection device 1, and the main chip 2 generates a compressor protection signal according to the detection signal transmitted by the basic detection device 1; a configuration module 20, the configuration module 20 is stacked with the basic module 10, the configuration module 20 is detachably connected to the basic module 10, and the configuration module 20 is provided with an isolation communication device 3 signal-connected to the main chip 2, and the compressor protection module performs isolation communication with the outside through the isolation communication device 3.

[0029] Specifically, by setting up the basic module 10, the basic detection device 1 transmits the detection signal to the main chip 2. The main chip 2 judges the detection signal and then generates a protection signal to protect the compressor. By setting up the configuration module 20, an isolation communication device 3 is provided on the configuration module 20. When the compressor operates at high voltage or when there are large external harmonics, there are always some interferences coupled from the power line to the communication line, affecting the communication quality. When adding communication with an isolation circuit, it can avoid interference when the compressor protection module communicates with the outside world, improving the protection effect of the compressor protection module. At the same time, the configuration module 20 is detachably connected to the basic module 10, enabling the configuration module 20 to be optionally connected to the basic module 10. When there is no need to add the configuration module 20 and the isolation communication device 3, the configuration module 20 can be removed.

[0030] It can be understood that, in addition to the basic detection device, more detection devices can be configured on the configuration module 20 to achieve comprehensive protection of the compressor.

[0031] Through the above settings, a basic detection device 1 is provided in the basic module 10, and an isolation communication device 3 is installed in the configuration module 20, which can reduce interference during the communication process. Using the design of assembling two-layer upper and lower main boards to distinguish the high and low configuration schemes of the product, it can be used in different scenarios, improving the protection effect of the compressor protection module and solving the technical problem that the protection effect of the compressor protection module on the compressor is poor in the related art.

[0032] Specifically, the basic module 10 includes a circuit board, and both the basic detection device 1 and the main chip 2 are installed on the circuit board; the configuration module 20 also includes a circuit board, and the isolation communication device 3 is installed on the circuit board in the configuration module 20.

[0033] In the compressor protection module of this embodiment, refer to Figure 1 , the compressor protection module includes a support structure 4. Both ends of the support structure 4 are respectively connected to the basic module 10 and the configuration module 20, and the support structure 4 is used to support the configuration module 20.

[0034] Specifically, the configuration module 20 is located on the upper layer, and the basic module 10 is located on the lower layer. The configuration module 20 is supported by the support structure 4.

[0035] In the compressor protection module of this embodiment, refer to Figure 1 , the support structure 4 includes conductive pins, and the conductive pins are respectively electrically connected to the basic module 10 and the configuration module 20. Specifically, through the conductive pins, while supporting the configuration module 20, electrical connection can be achieved between the basic module 10 and the configuration module 20.

[0036] It can be understood that both ends of the conductive pin are respectively inserted into the circuit boards in the basic module 10 and the configuration module 20.

[0037] In the compressor protection module of this embodiment, refer to Figure 2 , the basic detection device 1 includes a voltage detection device 11 and a temperature detection device 12. The voltage detection device 11 is used to obtain the voltage in the compressor circuit, and the temperature detection device 12 is used to obtain the temperature of the compressor motor. Specifically, temperature detection and voltage detection are set in the basic module 10 to meet the basic detection requirements of the compressor protection module.

[0038] In the compressor protection module of this embodiment, refer to Figure 2 , the configuration module 20 is provided with a current detection module 5. The current detection module 5 is used to obtain the current in the compressor circuit, and the current detection module 5 is signal-connected to the main chip 2. By setting the current detection module 5, it is directly used to detect the current of the compressor and monitor the current change of the compressor in real time. The current detection module 5 can completely replace the ammeter, saving the cost of the compressor protection module. At the same time, combined with the original voltage detection, the power of the compressor is predicted, and the power change of the compressor is understood in real time. By adding a current detection circuit and an isolation communication circuit in the configuration module 20, the real-time detection of the current at the front end of the compressor is realized, and the compressor motor is comprehensively protected in combination with voltage detection.

[0039] In some embodiments, an additional temperature detection device can be added to the configuration module 20.

[0040] In the compressor protection module of this embodiment, the two-layer upper and lower main board assembly method is used to distinguish the high and low configuration schemes of the product. The basic module 10 is provided with voltage detection and temperature detection, and the configuration module 20 is provided with current detection and isolation communication. In the low configuration scheme, only the basic module 10 is used. In the high configuration scheme, the configuration module 20 can be added. The high or low configuration scheme can be selected according to the customer's needs or equipment requirements for different scenarios.

[0041] For example, when the environmental interference is large and all functions are required, the high configuration scheme is selected: the high configuration scheme includes two main boards, the basic module 10 and the configuration module 20, covering functions such as voltage detection, multiple temperature detections, current detection, power detection, and isolation communication; on the contrary, the low configuration only requires the basic module 10, which only has voltage detection and one temperature detection function, effectively saving costs.

[0042] In the compressor protection module of this embodiment, refer to Figure 2, the compressor protection module includes: a three-phase power supply 6, which is arranged on the base module 10; a single-phase power supply 7, which is arranged on the base module 10. Specifically, devices such as three-phase voltage detection and single-phase power supply input in the strong electricity part are designed on the base module 10, and the three-phase current detection device and the isolation communication circuit in the weak electricity are designed on the configuration module 20, cleverly avoiding the intersection of strong electricity and weak electricity and realizing the separation of strong and weak electricity.

[0043] In the compressor protection module of this embodiment, refer to Figure 2 , the base module 10 includes a first mounting surface 101 for mounting the base detection device 1 and the main chip 2, and the configuration module 20 includes a second mounting surface 201 for mounting the isolation communication device 3. The first mounting surface 101 and the second mounting surface 201 are arranged opposite to each other. Specifically, the base module 10 and the configuration module 20 are connected face to face, thereby reducing the overall space of the compressor protection module.

[0044] In the compressor protection module of this embodiment, refer to Figure 1 , there are multiple conductive pins. All the multiple conductive pins are electrically connected to the configuration module 20 and the base module 10, and the multiple conductive pins are arranged at intervals. By setting multiple conductive pins, the support strength for the configuration module 20 is increased.

[0045] In the compressor protection module of this embodiment, refer to Figure 2 , the base module 10 is provided with a relay control circuit 8, and the relay control circuit 8 is signal-connected to the main chip 2. By setting the relay control circuit 8, the on-off of the relay can be controlled according to the protection signal.

[0046] In the compressor of this embodiment, the compressor includes the above-mentioned compressor protection module.

[0047] Applying the compressor protection module in this embodiment to the compressor, the compressor protection module in this embodiment is added with a current detection circuit and an isolation communication circuit, realizing real-time detection of the current at the front end of the compressor, and jointly performing comprehensive protection on the compressor motor in combination with voltage detection, improving the service life of the compressor.

[0048] Next, in combination with Figure 4 An optional embodiment is introduced:

[0049] Refer to Figure 4, in this embodiment, the compressor protection module adopts a double-layer main board design. For the strong electricity part: three-phase voltage detection, single-phase power supply input, and temperature detection are designed in the underlying basic module 10, while three-phase weak current detection and isolated communication are designed in the upper-layer configuration module 20. Electrical connection and support between the two main boards can be achieved with three conductive pins, cleverly avoiding the intersection of strong electricity and weak electricity. When only using the compressor with basic functions, the upper-layer configuration module 20 can be cancelled to save costs, and high- and low-configuration products can be used in different scenarios. Additionally, the basic module 10 and the configuration module 20 are designed to be connected face-to-face at the top layer, that is, the configuration module 20 is installed upside down on the basic module 10, and the tall components of the configuration module 20 and the short components of the basic module 10 are as close as possible to reduce the overall space.

[0050] In this embodiment, the compressor protection module is added with a current detection circuit to directly detect the current of the compressor and monitor the current change of the compressor in real time, which can completely replace the electricity meter and save a lot of costs. At the same time, combined with the original voltage detection, the power of the compressor is predicted to understand the power change of the compressor in real time. In this embodiment, the compressor protection module is added with an isolated communication circuit. When the compressor operates at high voltage or there are large external harmonics, there are always some interferences coupled from the power line to the communication line, affecting the communication quality. When adding communication with an isolation circuit, the communication will not be affected by the interference coupled from the power line. By adding a current detection circuit and an isolated communication circuit, real-time detection of the current at the front end of the compressor is achieved, and combined with voltage detection, comprehensive protection of the compressor motor is carried out; the high- and low-configuration solutions of the product are distinguished by using the method of assembling two upper and lower main boards. The underlying basic module 10 completes voltage detection and temperature detection, and the upper-layer configuration module 20 completes current detection and isolated communication, which can be used in different scenarios.
