Description

Technical Field

[0001] This application belongs to the field of electrical technology, specifically relating to an electronic control component and a refrigeration device. Background Technology

[0002] In the field of refrigeration technology, refrigeration equipment such as refrigerators and freezers have become an indispensable part of people's daily lives. These devices achieve precise temperature control within a space through complex internal systems to meet various needs such as food preservation, pharmaceutical storage, and industrial cooling.

[0003] The refrigeration equipment has electrical control components to control its operation, and the equipment's casing has an opening to house the electrical control box. However, in the prior art, in order to fit the electrical control box into the casing, the opening area is relatively large, affecting the aesthetics. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an electronic control component and a refrigeration device, which aims to solve the technical problems to at least a certain extent.

[0005] The technical solution of this utility model is as follows:

[0006] An electronic control component, characterized in that it comprises: an electronic control box, wherein a display panel and a main control board are disposed within the electronic control box; a display unit is disposed on a first side of the display panel; the main control board is disposed on a second side of the display panel and electrically connected to the display panel, wherein the first side of the display panel and the second side of the display panel are disposed opposite to each other; wherein, along the thickness direction of the display panel, the projected area of ​​the display panel is smaller than the projected area of ​​the main control board, and / or, at least one edge of the main control board protrudes beyond the edge of the display panel.

[0007] In some implementations, one edge of the main control board protrudes beyond the edge of the display panel, and the remaining edge of the main control board is within the projection range of the display panel or exceeds the projection range of the display panel within a preset distance along a direction perpendicular to the display panel.

[0008] In some implementations, the display panel is positioned perpendicular to the main control board.

[0009] In some implementations, the main control board has a first mounting portion and a second mounting portion; wherein the first mounting portion integrates a rectifier circuit, the second mounting portion integrates a frequency adjustment circuit, and the main control board further includes a main control circuit, which is integrated in the first mounting portion and / or the second mounting portion.

[0010] In some implementations, the rectifier circuit includes: a common-mode inductor disposed in the first mounting portion; a rectifier bridge disposed in the first mounting portion and electrically connected to the common-mode inductor; and an electrolytic capacitor disposed in the first mounting portion and electrically connected to the frequency adjustment circuit and the main control circuit.

[0011] In some implementations, the main control circuit includes: a voltage conversion circuit disposed in the first mounting portion and electrically connected to the rectifier circuit and the display panel; and a control circuit disposed in the first mounting portion and electrically connected to the voltage conversion circuit, the frequency adjustment circuit, and the display panel.

[0012] In some implementations, the frequency adjustment circuit includes a multi-channel single-phase inverter circuit.

[0013] In some implementations, the single-phase inverter circuit includes: a drive protection circuit electrically connected to the main control circuit; and an insulated gate bipolar transistor electrically connected to the rectifier circuit and the drive protection circuit.

[0014] In some implementations, the display panel has a temperature adjustment trigger circuit, and the electronic control box is provided with an operating element for triggering the temperature adjustment trigger circuit.

[0015] In some implementations, the electrical control box has a display hole, and the display unit is opposite to the display hole.

[0016] Based on the same inventive concept, this utility model also provides a refrigeration device, including a housing and the aforementioned electrical control components. The housing has a receiving cavity and an opening communicating with the receiving cavity, and the electrical control box passes through the opening and is installed in the receiving cavity.

[0017] The beneficial effects of this utility model include at least the following:

[0018] Since the control box contains a display board and a main control board, housing the display board and main control board within the control box prevents them from being exposed, thus ensuring their safety and aesthetics.

[0019] Since a display section is located on the first side of the display panel, it can display the operating parameters of the refrigeration equipment. The main control board is located on the second side of the display panel and is electrically connected to it. The first and second sides of the display panel are positioned opposite each other. Along the thickness direction of the display panel, the projected area of ​​the display panel is smaller than the projected area of ​​the main control board, and / or, at least one edge of the main control board protrudes beyond the edge of the display panel. Therefore, when designing the electrical control box to house the display panel and the main control board, the projection area of ​​the display panel along its thickness direction can be considered. The control box is designed based on the projection area of ​​the main control board and the projection area of ​​the main control board, and or, based on the fact that at least one edge of the main control board protrudes beyond the edge of the display board, the control box has a receiving area opposite to the edges of the display board and the main control board protruding beyond the display board. The outline of the receiving area needs to be adapted to the edges of the display board and the main control board protruding beyond the display board. That is to say, the part of the outline of the receiving area opposite to the edge of the main control board protruding beyond the display board will be recessed to reduce the space occupied by the control box and achieve miniaturization.

[0020] When installing the control box into the refrigeration equipment's cabinet, the control box is inserted into the cabinet's receiving cavity through an opening in the cabinet. At this point, the portion of the receiving area that aligns with the edge of the main control board protruding from the display panel enters the receiving cavity through the opening. The portion of the receiving area that aligns with the display panel can close the opening, reducing its area. In other words, along the installation direction of the control box, the projected area of ​​the opening on the cabinet is smaller than the projected area of ​​the entire control box on the cabinet. Understandably, while ensuring the control box can be installed smoothly into the receiving cavity, the opening can be made smaller and more concealed, improving the overall aesthetics of the refrigeration equipment's cabinet and making it look cleaner and more upscale.

[0021] The outline of the receiving area and the portion of the main control board that protrudes beyond the display panel are recessed to form a clearance notch. This clearance notch provides additional space for the installation of the control box. When the control box is placed into the enclosure, it can be directly inserted at an angle into the opening, avoiding obstructions from the edge of the opening or other surrounding structures of the enclosure. This makes the installation process smoother and reduces installation difficulties caused by size mismatch or insufficient space, ensuring a smooth installation of the control box.

[0044] This application is described below with reference to the accompanying drawings and specific embodiments:

[0045] The electronic control component and refrigeration equipment provided in this embodiment are intended to solve technical problems to at least a certain extent.

[0046] Combination Figure 1 , Figure 2 and Figure 3The electronic control assembly of this application embodiment includes: an electronic control box 10, a display panel 20, and a main control board 30. The electronic control box 10 houses the display panel 20 and the main control board 30. A display section 22 is provided on a first side of the display panel 20. The main control board 30 is disposed on a second side of the display panel 20 and is electrically connected to the display panel 20. The first side and the second side of the display panel 20 are disposed opposite to each other. Specifically, along the thickness direction of the display panel 20, the projected area of ​​the display panel 20 is smaller than the projected area of ​​the main control board 30, and / or, at least one edge of the main control board 30 protrudes beyond the edge of the display panel 20.

[0047] The display unit 22 can be a display screen.

[0048] Since the control box 10 contains a display board 20 and a main control board 30, the control box 10 houses the display board 20 and the main control board 30, thus preventing the display board 20 and the main control board 30 from being exposed to the outside, ensuring the safety of the display board 20 and the main control board 30, and also ensuring aesthetics.

[0049] Since a display unit 22 is provided on the first side of the display panel 20, the display unit 22 can display the operating parameters of the refrigeration equipment. Since the main control board 30 is located on the second side of the display panel 20 and is electrically connected to the display panel 20, the first side and the second side of the display panel 20 are arranged opposite to each other. Along the thickness direction of the display panel 20, the projected area of ​​the display panel 20 is smaller than the projected area of ​​the main control board 30, and / or, at least one edge of the main control board 30 protrudes beyond the edge of the display panel 20. Therefore, when designing the electrical control box 10 that houses the display panel 20 and the main control board 30, the display panel 20 can be arranged according to the thickness direction of the display panel 20. The control box 10 is designed based on the projected area of ​​the main control board 30 and the projected area of ​​the main control board 30, and or, the control box 10 is designed based on at least one edge of the main control board 30 protruding from the edge of the display board 20. The control box 10 has a receiving area opposite to the edge of the display board 20 and the edge of the main control board 30 protruding from the display board 20. The outline of the receiving area needs to be adapted to the edge of the display board 20 and the edge of the main control board 30 protruding from the display board 20. That is, the part of the outline of the receiving area opposite to the edge of the main control board 30 protruding from the display board 20 will be recessed to reduce the space occupied by the control box 10 and achieve miniaturization.

[0050] Since the main control board 30 performs the main control work, it has many electronic components and occupies a large volume. In other words, the area occupied by the main control board 30 is larger than that occupied by the display board 20. The difference between the area occupied by the main control board 30 and the area occupied by the display board 20 will form a recess. The first side of the display board 20 is provided with a display section 22, and the main control board 30 is located on the second side of the display board 20, which allows the display board 20 to be exposed in the electrical control box 10 for easy observation by the user.

[0051] Combination Figure 1 , Figure 9 and Figure 10 When the control box 10 is to be installed inside the housing 60 of the refrigeration equipment, the control box 10 is inserted into the receiving cavity 61 of the housing 60 through the opening 62 on the housing 60. At this time, the part of the receiving area that is opposite to the edge of the main control board 30 protruding from the display panel 20 enters the receiving cavity 61 through the opening 62. The part of the receiving area that is opposite to the display panel 20 can close the opening 62, which can reduce the area of ​​the opening 62. That is, along the installation direction of the control box 10, the projected area of ​​the opening 62 on the housing 60 is smaller than the projected area of ​​the entire control box 10 on the housing 60. It can be understood that, on the premise of ensuring that the control box 10 can be smoothly installed into the receiving cavity 61, the opening 62 can be made smaller and more concealed, which improves the overall appearance of the housing 60 of the refrigeration equipment and makes the housing 60 look cleaner and more high-end.

[0052] Combination Figure 1 , Figure 9 and Figure 10 The outline of the accommodating area and the portion of the main control board 30 that protrudes from the edge of the display panel 20 are recessed to form a clearance notch. The existence of the clearance notch provides additional space for the installation of the electrical control box 10. When the electrical control box 10 is placed into the housing 60, it can be directly inserted diagonally into the opening 62, avoiding the edge of the opening 62 or other obstructions from the surrounding structure of the housing 60 through the clearance notch, making the installation process smoother and reducing installation difficulties caused by size mismatch or insufficient space, thus ensuring smooth installation of the electrical control box 10.

[0053] Combination Figure 2 and Figure 3 In some embodiments, in order to reduce the space occupied by the control box 10, one edge of the main control board 30 protrudes beyond the edge of the display board 20, and the remaining edge of the main control board 30 is within the projection range of the display board 20 or exceeds the projection range of the display board 20 within a preset distance along a direction perpendicular to the display board 20, so that the outline of the accommodating area is recessed relative to the edge of the main control board 30 protruding beyond the display board 20, thereby achieving miniaturization of the control box 10.

[0054] Combination Figure 2 and Figure 3In some embodiments, to facilitate the arrangement of the main control board 30 and the display board 20 within the electrical control box 10, the display board 20 is arranged perpendicularly to the main control board 30. This effectively avoids direct overlap between the two in the horizontal or vertical direction, thereby maximizing the utilization of the three-dimensional space within the electrical control box 10. This allows the entire electrical control assembly to achieve more compact and efficient space utilization while maintaining functional integrity, which is conducive to the miniaturization and lightweight design of the product. Moreover, the main control board 30 and the display board 20 generate a certain amount of heat during operation. Arranging the main control board 30 and the display board 20 at an angle can increase the airflow path, which is beneficial for heat dissipation and heat dissipation efficiency. This can ensure the stable operation of the electrical control assembly, extend its service life, and reduce failures caused by overheating.

[0055] Combination Figure 6 In some embodiments, to improve the integration of the main control board 30, the main control board 30 has a first mounting portion 32 and a second mounting portion 33. The first mounting portion 32 integrates a rectifier circuit 34, the second mounting portion 33 integrates a frequency adjustment circuit 31, and the main control board also includes a main control circuit 35, which is integrated into the first mounting portion 32 and / or the second mounting portion 33.

[0056] Since the main control board 30 has a first mounting part 32 and a second mounting part 33, the first mounting part 32 integrates a rectifier circuit 34, the second mounting part 33 integrates a frequency adjustment circuit 31, and the main control circuit 35 is integrated into the first mounting part 32 and / or the second mounting part 33, the main control board 30 integrates the rectification function, control function, and frequency adjustment function into one unit, realizing the merging of functional units, thereby reducing the number of independent parts. The integrated design eliminates the intermediate connecting parts (such as wire harnesses, connectors, etc.) originally used to connect various components, reducing assembly difficulty, reducing the types and quantities of parts, reducing costs, and also reducing connection steps and the number of interfaces, simplifying the assembly process, improving production efficiency, and shortening the production cycle. Moreover, it can reduce assembly errors caused by improper connection between multiple parts, allowing the main control board 30 to be installed as a whole, reducing the cumulative errors caused by assembling parts one by one, and improving the overall assembly accuracy. At the same time, the integrated design makes the main control board 30 more compact in spatial layout, reducing the space occupied by multiple parts scattered.

[0057] The rectifier circuit 34 rectifies the 220V AC power from the external power supply into 310V DC power, and supplies the 310V DC power to the main control circuit 35 and the frequency adjustment circuit 31 respectively, so as to realize the power-on of various circuits on the main control board 30.

[0058] The main control circuit 35 can be entirely located in the first mounting part 32 or entirely located in the second mounting part 33. The main control circuit 35 can also be partially located in the first mounting part 32 and partially located in the second mounting part 33.

[0059] In some embodiments, in order to control the compressor of the refrigeration equipment, the frequency adjustment circuit 31 includes at least one of a variable frequency adjustment circuit and a fixed frequency adjustment circuit.

[0060] When the frequency adjustment circuit 31 is a variable frequency adjustment circuit, the variable frequency adjustment circuit can dynamically change the frequency of the signal as needed. By adjusting the power supply frequency of the compressor, more precise control and higher operating efficiency can be achieved.

[0061] When the frequency adjustment circuit 31 is a fixed frequency adjustment circuit, the fixed frequency adjustment circuit can keep the frequency of the signal stable and the working state is relatively fixed. Therefore, its reliability is usually high, ensuring the stability and reliability of the compressor during long-term operation.

[0062] In some embodiments, in order to ensure the normal operation of the main control board 30, the first mounting part 32 and the second mounting part 33 are located at both ends of the main control board 30 to reduce electromagnetic interference between the rectifier circuit 34 and the main control circuit 35 and the frequency adjustment circuit 31.

[0063] Of course, in some other embodiments, the first mounting part 32 and the second mounting part 33 may be located in the non-end regions of the main control board 30, such as the middle of the main control board 30.

[0064] Combination Figure 6 and Figure 7 In some embodiments, to achieve rectification, the rectifier circuit 34 includes a common-mode inductor 341, a rectifier bridge 342, and an electrolytic capacitor 343. The common-mode inductor 341 is disposed in the first mounting portion 32. The rectifier bridge 342 is disposed in the first mounting portion 32 and electrically connected to the common-mode inductor 341. The electrolytic capacitor 343 is disposed in the first mounting portion 32 and electrically connected to the frequency adjustment circuit 31 and the main control circuit 35.

[0065] An external power supply delivers 220V AC to the common-mode inductor 341. The common-mode inductor 341 suppresses common-mode interference signals in the circuit to ensure the stability and reliability of the circuit system. The filtered 220V AC from the common-mode inductor 341 is then delivered to the rectifier bridge 342. The rectifier bridge 342 rectifies the 220V AC into 310V DC and delivers the 310V DC to the electrolytic capacitor 343 for voltage regulation. The electrolytic capacitor 343 then delivers the regulated 310V DC to the frequency adjustment circuit 31 and the main control circuit 35.

[0066] Combination Figure 7 and Figure 8 In some embodiments, to achieve control, the main control circuit 35 includes a voltage conversion circuit 351 and a control circuit 352. The voltage conversion circuit 351 is disposed in the first mounting portion 32 and electrically connected to the rectifier circuit 34 and the display panel 20. The control circuit 352 is disposed in the first mounting portion 32 and electrically connected to the voltage conversion circuit 351, the frequency adjustment circuit 31, and the display panel 20. The control circuit 352 may be an MCU (Micro Control Unit).

[0067] The rectifier circuit 34 delivers 310V DC power to the voltage conversion circuit 351, which steps down the 310V DC power to 15V DC power and then delivers the 15V DC power to the control circuit 352.

[0068] In some embodiments, in order to ensure the stability of the operation of the control circuit 352, the control circuit 352 and the voltage conversion circuit 351 are arranged opposite to each other to reduce the distance between the control circuit 352 and the voltage conversion circuit 351, reduce the trace length, reduce the voltage drop, and enable the voltage output by the voltage conversion circuit 351 to be transmitted to the control circuit 352 more accurately. At the same time, the space of the main control board 30 can be fully utilized, realizing the compact design of the main control board 30, reducing the overall size, and improving the space utilization rate.

[0069] Combination Figure 7 and Figure 8 In some embodiments, the frequency adjustment circuit 31 includes a multi-channel single-phase inverter circuit 311, which can efficiently convert direct current into alternating current to control the operation of the compressor of the refrigeration equipment.

[0070] In some embodiments, to enable the operation of the compressor in a refrigeration device, the single-phase inverter circuit 311 includes a drive protection circuit 3111 and an insulated-gate bipolar transistor 3112. The drive protection circuit 3111 is electrically connected to the main control circuit 35. The insulated-gate bipolar transistor 3112 is electrically connected to the rectifier circuit 34 and the drive protection circuit 3111.

[0071] The rectifier circuit 34 supplies 310V DC power to the insulated gate bipolar transistor 3112, and the main control circuit 35 supplies 15V DC power to the drive protection circuit 3111. The drive protection circuit 3111 controls the switching of the 310V DC power between the rectifier circuit 24 and the insulated gate bipolar transistor 3112 according to the 15V DC power, so that the insulated gate bipolar transistor 3112 controls the operation of the compressor.

[0072] In some embodiments, in order to ensure the stability of the single-phase inverter circuit 311, the drive protection circuit 3111 and the insulated gate bipolar transistor 3112 are arranged back to back to reduce the spacing between the drive protection circuit 3111 and the insulated gate bipolar transistor 3112, thereby reducing the trace length and voltage drop. This allows the voltage output by the drive protection circuit 3111 to be transmitted to the insulated gate bipolar transistor 3112 more accurately. At the same time, the space of the main control board 20 can be fully utilized, achieving a compact design of the main control board 30, reducing the overall size, and improving space utilization.

[0073] Combination Figure 6 and Figure 7 In some embodiments, to ensure the normal operation of the main control board 30, the electronic control component further includes a safety circuit 50. The safety circuit 50 is integrated into the first mounting part 32 and is electrically connected to the rectifier circuit 24. An external power supply delivers 220V AC power to the safety circuit 50, and the safety circuit 50 delivers 220V AC power to the rectifier circuit 24.

[0074] The safety circuit 50 includes a residual current device (RCD) that can monitor leakage current in the circuit in real time. Once leakage current is detected, the RCD will quickly cut off the circuit to prevent current from leaking to the human body or other equipment, thereby avoiding safety accidents such as electric shock or short circuit.

[0075] The Safety Circuit 50 also features overload protection. When the current in the circuit exceeds the rated value, the overload protector will be triggered, cutting off the circuit to prevent electrical equipment from being damaged by overload or causing dangerous situations such as fires.

[0076] When a short circuit occurs, the short-circuit protector in the safety circuit 50 will immediately disconnect the circuit to prevent the short-circuit current from damaging the circuit and equipment, thus ensuring the stability and safety of the circuit.

[0077] Combination Figure 3 and Figure 5 In some embodiments, in order to trigger the main control board 30, the display board 20 has a temperature adjustment trigger circuit 21, and the electrical control box 10 is provided with an operating element 40 for triggering the temperature adjustment trigger circuit 21. The temperature adjustment trigger circuit 21 is electrically connected to the main control circuit 35 of the main control board 30.

[0078] The operating component 40 can be a temperature control button. Pressing the temperature control button will activate the temperature adjustment trigger circuit 21 to input an adjustment signal to the main control circuit 35.

[0079] The operating element 40 can be a touch-sensitive operating element. Pressing the touch-sensitive operating element will activate the temperature adjustment trigger circuit 21 to input an adjustment signal to the main control circuit 35.

[0080] The operating component 40 can be a knob, with the knob part located outside the control box 10 and the other part passing through the control box 10 and connected to the temperature adjustment trigger circuit 21.

[0081] When the temperature of the refrigeration equipment needs to be adjusted, the operating component 40 is operated. The operating component 40 can trigger the main control circuit 35 of the main control board 30 through the temperature adjustment trigger circuit to input an adjustment signal to the main control circuit 35. The main control circuit 35 sends a control signal to the frequency adjustment circuit 31 according to the adjustment signal. The frequency adjustment circuit 31 is electrically connected to the compressor. The frequency adjustment circuit 31 sends a frequency adjustment signal to the compressor according to the control signal to control the operation of the compressor.

[0082] The display panel 20 integrates the temperature adjustment trigger circuit 21 and the display unit 22, combining the display function and the temperature adjustment trigger function into one unit. This merging of functional units reduces the number of independent components. The integrated design eliminates intermediate connectors (such as wire harnesses and connectors) that were originally used to connect various components, reducing assembly difficulty, the types and number of components, and costs. It also reduces connection steps and the number of interfaces, simplifying the assembly process, improving production efficiency, and shortening the production cycle. Moreover, it reduces assembly errors caused by improper connections between multiple components, allowing the main control board 30 to be installed as a whole, reducing the cumulative errors caused by assembling components one by one, and improving overall assembly accuracy. At the same time, the integrated design makes the display panel 20 more compact in its spatial layout, reducing the space occupied by multiple components that are scattered.

[0083] In some embodiments, the control circuit 352 of the main control board 30 is equipped with an LDO (Low Drop Out) module, which reduces the 15V DC power of the control circuit 352 to 5V DC power and sends the 5V DC power to the temperature adjustment trigger circuit 21.

The cover 15 is detachably connected to the housing 14. When the control circuit assembly 20 is to be installed, the cover 15 is removed from the housing 14, allowing the display panel 20 and the main control board 30 to be installed within the housing 14, thus improving installation efficiency. The cover 15 is then reconnected to the housing 14, sealing the housing 14 to prevent the display panel 20 and the main control board 30 from being exposed, thereby ensuring the safety of the display panel 20 and the main control board 30.

[0085] Combination Figure 1 and Figure 4In some embodiments, in order to facilitate observation of the display unit 22, the control box 10 is provided with a display hole 13. The display unit 22 is opposite to the display hole 13, and the display hole 13 can directly display the data of the display unit 22. Users can easily observe the data without opening the cover 12 of the control box 10 or moving other parts, which improves the convenience of observation.
