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] However, in the existing technology, the temperature controller and frequency regulator of the refrigeration equipment are independent components. After the temperature controller is assembled, it is also necessary to connect it with the frequency regulator through a wiring harness, which makes the assembly difficult, the number of parts large, and the cost high. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an electronic control component and a refrigeration device, aiming to at least partially solve the technical problem that after the temperature controller is assembled, it still needs to be connected to the frequency regulator via a wiring harness, resulting in high assembly difficulty, a large number of parts, and high costs.

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

[0006] An electronic control component is characterized by comprising: a control circuit board integrating a main control circuit and a frequency adjustment circuit, wherein the control circuit board is provided with a temperature adjustment trigger unit electrically connected to the main control circuit; and an operating element corresponding to the temperature adjustment trigger unit; wherein, when the operating element is activated, the main control circuit can be triggered through the temperature adjustment trigger unit to cause the frequency adjustment circuit to emit a frequency adjustment signal.

[0007] In some implementations, the control circuit board is located on the panel, the operating part is located outside the panel, and the other part passes through the panel and is connected to the temperature adjustment trigger.

[0008] In some implementations, the control circuit board integrates indicator lights, and the panel has light-emitting holes for the light from the indicator lights to be exposed on the panel.

[0009] In some implementations, the electronic control component further includes a light guide that passes through the light outlet and covers the indicator light.

[0010] In some embodiments, the electrical control box includes: a box body; a box cover, detachably connected to the box body; wherein the box body or the box cover includes the panel.

[0011] In some implementations, along the direction of the panel toward the housing, the projection of the panel at least partially falls on a portion of the housing and / or the projected area of ​​the panel is smaller than the projected area of ​​the housing.

[0012] In some implementations, one of the box body and the box lid is provided with a first buckle, and the other is provided with a slot, wherein the first buckle is engaged with the slot.

[0013] In some implementations, the electrical control box is provided with a first support and a second support, both of which abut against the control circuit board; wherein the first support and the second support are located on opposite sides of the control circuit board.

[0014] In some implementations, the control circuit board has a notch, and the electronic control component further includes a power line, comprising a first segment and a second segment connected to the first segment. The first segment passes through the electronic control box and is located inside the electronic control box. One end of the second segment passes through the notch and is connected to the first segment, and the other end is electrically connected to the control circuit board. The first segment and the second segment are located on opposite sides of the control circuit board.

[0015] In some implementations, the frequency adjustment circuit includes at least one of a frequency conversion adjustment circuit and a fixed frequency adjustment circuit.

[0016] In some implementations, the operating element includes a knob.

[0017] Based on the same inventive concept, this utility model also provides a refrigeration device, including a housing and the aforementioned electrical control component. The housing has a receiving cavity and an opening communicating with the receiving cavity. The electrical control box of the electrical control component passes through the opening and is installed in the receiving cavity. The opening and the operating component are located on the same side of the housing.

[0018] In some implementations, the control box panel and the opening are located on the same side of the housing, and the operating element passes through the panel and is connected to the temperature adjustment trigger.

[0019] In some implementations, the cover of the electrical control box is located inside the receiving cavity.

[0020] In some implementations, the electrical control box is provided with a second latch that abuts against the cavity wall of the receiving cavity.

[0021] In some implementations, the electrical control box is provided with a limiting member that abuts against the inner wall of the opening; wherein the limiting member is angled to the second buckle.

[0022] The beneficial effects of this utility model include at least the following:

[0023] Because the control circuit board integrates the main control circuit and the frequency adjustment circuit, it combines control and frequency adjustment functions into one unit, thus reducing 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, reducing the types and number of components, lowering costs, 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 connections between multiple components, allowing the control circuit board 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 control circuit board more compact in terms of spatial layout, reducing the space occupied by multiple components that are scattered.

[0024] Because the control circuit board is equipped with a temperature adjustment trigger that is electrically connected to the main control circuit, and the operating component is correspondingly set with the temperature adjustment trigger, when the temperature needs to be adjusted, the user can directly operate the operating component to make the operating component drive the temperature adjustment trigger to move, thereby realizing the temperature adjustment. This simplifies the operation steps, improves the user experience, and reduces the risk of the user directly contacting electrical components, thus improving safety.

[0025] When the operating element is activated, the main control circuit can be triggered by the temperature adjustment trigger, which causes the frequency adjustment circuit to send a frequency adjustment signal. It can be understood that the operating element drives the temperature adjustment trigger to activate, thereby inputting an adjustment signal to the main control circuit. The main control circuit sends a control signal to the frequency adjustment circuit according to the adjustment signal. The frequency adjustment circuit is electrically connected to the compressor, and the frequency adjustment circuit sends a frequency adjustment signal to the compressor according to the control signal to control the operation of the compressor.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0060] This application is described below with reference to the accompanying drawings and specific embodiments:

[0061] The electronic control component and refrigeration equipment provided in this embodiment aim to solve, to some extent, the technical problem that after the temperature controller is assembled, it is still necessary to connect it with the frequency regulator through a wiring harness, which leads to high assembly difficulty, a large number of parts, and high cost.

[0062] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The electronic control component in this embodiment includes a control circuit board 20 and an operating element 30. The control circuit board 20 integrates a main control circuit and a frequency adjustment circuit, and is provided with a temperature adjustment trigger unit electrically connected to the main control circuit. The operating element 30 is correspondingly provided with the temperature adjustment trigger unit. When the operating element 30 is activated, the main control circuit can be triggered through the temperature adjustment trigger unit, so that the frequency adjustment circuit sends a frequency adjustment signal.

[0063] The main control circuit can not only control the temperature of the refrigeration equipment, but also control the operation of the fan and the defrosting of the refrigeration equipment.

[0064] The frequency adjustment circuit includes a signal input port electrically connected to the main control circuit and a signal output port connected to the compressor.

[0065] Because the control circuit board 20 integrates the main control circuit and the frequency adjustment circuit, it combines the control function and the frequency adjustment function into one unit, thus reducing the number of independent parts. The integrated design eliminates the intermediate connectors (such as wire harnesses, connectors, etc.) that were originally used to connect the various components, reducing assembly difficulty, reducing the types and number 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 components, allowing the control circuit board 20 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 control circuit board 20 more compact in spatial layout, reducing the space occupied by multiple components scattered.

[0066] Since the control circuit board 20 is equipped with a temperature adjustment trigger part that is electrically connected to the main control circuit, and the operating element 30 is correspondingly set with the temperature adjustment trigger part, when it is necessary to adjust the temperature, the user can directly operate the operating element 30 so that the operating element 30 can drive the temperature adjustment trigger part to move, thereby realizing the temperature adjustment. This simplifies the operation steps, improves the user experience, and reduces the risk of the user directly contacting electrical components, thus improving safety.

[0067] When the operating element 30 is activated, the main control circuit can be triggered by the temperature adjustment trigger, so that the frequency adjustment circuit sends a frequency adjustment signal. It can be understood that the operating element 30 drives the temperature adjustment trigger to activate, so as to input the adjustment signal to the main control circuit. The main control circuit sends a control signal to the frequency adjustment circuit according to the adjustment signal. The frequency adjustment circuit is electrically connected to the compressor. The frequency adjustment circuit sends a frequency adjustment signal to the compressor of the refrigeration equipment according to the control signal, so as to control the operation of the compressor.

[0068] In some embodiments, in order to control the compressor of the refrigeration equipment, the frequency adjustment circuit includes at least one of a variable frequency adjustment circuit and a fixed frequency adjustment circuit.

[0069] When the frequency adjustment circuit 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.

[0070] When the frequency adjustment circuit 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.

[0071] In some embodiments, in order to facilitate operation of the operating element 30, the control circuit board 20 is disposed on the panel 16, and part of the operating element 30 is disposed outside the panel 16, while another part passes through the panel 16 and is connected to the temperature adjustment trigger part.

[0072] Since part of the operating element 30 is located outside the panel 16, and another part passes through the panel 16 and connects to the temperature adjustment trigger, when the temperature needs to be adjusted, the user can directly operate the operating element 30 outside the panel 16 so that the operating element 30 can drive the temperature adjustment trigger to move. In other words, the user can directly operate the temperature adjustment trigger through the operating element 30 without opening the panel 16, thereby adjusting the temperature. This simplifies the operation steps, improves the user experience, and reduces the risk of the user directly contacting electrical components, thus improving safety.

[0073] The operating component 30 can be a temperature control button. Pressing the temperature control button will activate the temperature adjustment trigger circuit to input an adjustment signal to the main control circuit.

[0074] The operating element 30 can be a touch-sensitive operating element. Pressing the touch-sensitive operating element activates the temperature adjustment trigger circuit, thereby inputting an adjustment signal to the main control circuit.

[0075] Combination Figure 3 In some embodiments, in order to further improve the integration of the control circuit board 20, the control circuit board 20 integrates indicator lights, and the panel 16 has a light-emitting hole 11 for the light of the indicator lights to be exposed to the control box 10.

[0076] The indicator light is electrically connected to the main control circuit. The main control circuit sends an indication signal to the indicator light to control the indicator light to turn on or off, so that the indicator light can display the operating status of the refrigeration equipment.

[0077] The control circuit board 20 integrates the main control circuit and indicator lights, combining control and indication functions 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) used to connect various components, reducing assembly difficulty, the types and quantities 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. Furthermore, it reduces assembly errors caused by improper connections between multiple components, allowing the control circuit board 20 to be installed as a whole. This reduces the cumulative errors caused by assembling components one by one, improving overall assembly accuracy. At the same time, the integrated design makes the control circuit board 20 more compact in its spatial layout, reducing the space occupied by multiple components that are scattered.

[0078] The light from the indicator light can penetrate the panel 16 directly and be clearly displayed outside the panel 16. Users or operators can intuitively understand the operating status of the equipment without opening the panel 16 or using other tools, which improves the convenience and safety of operation.

[0079] Panel 16 can be part of the housing 90 of the refrigeration equipment, a separate panel, or part of the electrical control box 10.

[0080] Combination Figure 1 , Figure 7 and Figure 8 In some embodiments, in order to guide the light from the indicator light to the outside of the panel 16, the electronic control assembly further includes a light guide 40. The light guide 40 passes through the light outlet 11 and covers the indicator light. When the indicator light is lit, the light emitted by it is captured by the light guide 40 and guided to the outside of the panel 16. This not only improves the efficiency of light utilization, but also makes the indicator light located inside the electronic control box 10 more aesthetically pleasing and concealed.

[0081] Combination Figure 7 and Figure 8 In order to facilitate the light guide 40 to guide the light emitted by the indicator light to the outside of the panel 16, the light guide 40 includes a first segment 41 and a second segment 42 connected to the first segment 41. The first segment 41 passes through the light outlet 11 and covers the indicator light, while the second segment 42 is located outside the panel 16.

[0082] When the indicator light is on, the light emitted by the indicator light is guided through the first segment 41 to the second segment 42 to guide the light of the indicator light to the outside of the panel 16. Through the continuous transmission from the first segment 41 to the second segment 42, the light of the indicator light can be more concentrated and more clearly propagated to the outside of the panel 16, making it easier for the observer to identify the status of the indicator light, thereby improving the user experience.

[0083] The outer diameter of the first segment 41 matches the inner diameter of the light-emitting hole 11, so that the first segment 41 can seal the light-emitting hole 11, preventing external debris from entering the panel 16 through the light-emitting hole 11, ensuring the safety of the control circuit board 20, protecting the control circuit board 20 from external environmental damage, and extending the service life of the control circuit board 20.

[0084] Combination Figure 7 and Figure 8In some embodiments, to limit the light guide 40, the area of ​​the second segment 42 is larger than the area of ​​the light outlet hole 11. When the light guide 40 is inserted into the panel 16, the second segment 42 will be stuck on the panel 16, achieving physical limitation and effectively preventing the light guide 40 from moving or falling out within the control box 10, ensuring stable light transmission. Moreover, when the light guide 40 needs maintenance or replacement, since the second segment 42 is located outside the panel 16, the second segment 42 can be directly operated. The second segment 42 drives the first segment 41, allowing the first segment 41 to be removed from the light outlet hole 11, thus achieving the disassembly of the light guide 40. The operation is simple and does not require disassembling the entire control box 10 or its complex internal structure to maintain or replace the light guide 40. At the same time, the second segment 42 can cover the gap between the first segment 41 and the light outlet hole 11 to ensure aesthetics.

[0085] Combination Figure 7 and Figure 8 In some embodiments, in order to allow the position of the light-emitting aperture 11 to be independent of the position of the indicator light, the first segment 41 is at least partially tilted. The light emitted by the indicator light is guided through the first segment 41 to the second segment 42 to guide the light of the indicator light to the outside of the panel 16. This allows the light-emitting aperture 11 and the indicator light to be set according to the specific position of the components set inside the control box 10, which helps to optimize the space utilization inside the control box 10 and provides more possibilities for the installation of other components on the control box 10.

[0086] In some embodiments, the first segment 41 can be integrally formed with the second segment 42, so that there are no additional connectors or seams between the first segment 41 and the second segment 42, thereby reducing the risk of loosening or breakage due to weak connection, enhancing the overall structural stability of the light guide 40, ensuring the continuity and stability of light in the transmission process. Since the first segment 41 can be seamlessly connected with the second segment 42, the light will not be lost due to reflection, scattering or absorption at the seam when it is transmitted from the first segment 41 to the second segment 42, improving the light transmission efficiency and ensuring that more light can reach the outside of the transmission panel 16.

[0087] In some embodiments, the light guide 40 abuts against the control circuit board 20, ensuring that light does not leak when passing through the light guide 40, thereby improving the utilization rate of light.

[0088] Combination Figure 1In some embodiments, for the convenience of user observation, the light-emitting hole 11 is necessarily located on the outer side of the panel 16. For the convenience of user operation, the light-emitting hole 11 and the operating component 30 are located on the same side of the panel 16. That is to say, the operating component 30 is partially located on the outer side of the panel 16. The user can see the status of the indicator light more intuitively through the light-emitting hole 11 and perform corresponding operations on the operating component 30 according to the prompts of the indicator light. This reduces the time that the user needs to find and confirm the position of the indicator light and improves the convenience and efficiency of operation.

[0089] Designing the light-emitting hole 11 and the operating component 30 on the same side can make more efficient use of the surface space of the control box 10. The compact layout helps to reduce the overall size of the control box 10. Moreover, it can enhance the design consistency of the control box 10, making the appearance of the control box neater and more orderly, and improving the overall aesthetics of the product.

[0090] Combination Figure 3 In some embodiments, the electronic control assembly further includes an electronic control box 10, within which the control circuit board 20 is housed. To facilitate the installation of the control circuit board 20 within the electronic control box 10, the electronic control box 10 includes a box body 12 and a box cover 13. The box cover 13 is detachably connected to the box body 12. When the control circuit board 20 needs to be installed, the box cover 13 is removed from the box body 12, allowing the control circuit board 20 to be installed inside the box body 12, thus improving installation efficiency. The box cover 13 is then reconnected to the box body 12, sealing the box body 12 to prevent the control circuit board 20 from being exposed, thus ensuring the safety of the control circuit board 20.

[0091] The control circuit board 20 is housed in the control box 10 to prevent it from being exposed and to ensure its safety.

[0092] The housing 12 or the cover 13 includes a panel 16. It is understood that the panel 16, as part of the housing 12 or the cover 13, allows the operating component 30 to be directly mounted thereon without the need for additional mounting brackets or components. This improves the overall structural integration of the control box 10, making the overall structure more compact and stable. Furthermore, the operating component 30 passes directly through the panel 16, allowing users to easily access and operate it without opening the cover 13 or moving other parts, thus improving operational convenience and efficiency. The panel 16 is the bottom wall of the housing 12 or the bottom wall of the cover 13; that is, the panel 16 is part of the housing 12 or the cover 13.

[0093] In some embodiments, when panel 16 is part of box body 12, panel 16 and box cover 13 are located on opposite sides of the body of box body 12. Of course, in other embodiments, when panel 16 is part of box cover 13, panel 16 and box body 12 are located on opposite sides of the body of box cover 13.

[0094] Combination Figure 1 , Figure 15 and Figure 16 In some embodiments, in order to facilitate the assembly of the control box 10 and to ensure aesthetics, the projection of the panel 16 toward the box body 12 is at least partially located in a portion of the box body 12 and / or the projected area of ​​the panel 16 is smaller than the projected area of ​​the box body 12.

[0095] When the control box 10 is to be installed inside the housing 90 of the refrigeration equipment, the box 12 is inserted into the receiving cavity 91 of the housing 90 through the opening 92 on the housing 90, and the box 12 is assembled into the receiving cavity 91. At this time, the panel 16 can close the opening 92. Since the projection of the panel 16 at least partially falls on a part of the box 12 and / or the projected area of ​​the panel 16 is smaller than the projected area of ​​the box 12, under the condition that the panel 16 closes the opening 92, the area of ​​the opening 92 matches the area of ​​the panel 16. Moreover, the box 12 can be inserted into the receiving cavity 91 at an angle through the opening 92, so that the box 12 can still enter the receiving cavity 91 smoothly, ensuring the convenience of installation. That is, it is not necessary to make the area of ​​the opening 92 greater than or equal to the area of ​​the box 12. In other words, the area of ​​the opening 92 can be smaller than the area of ​​the box 12, as long as the panel 16 can close the opening 92. At the same time, the box 12 can have enough space to accommodate the control circuit board 20. Understandably, while ensuring that the electrical control box 10 can be smoothly installed into the receiving cavity 91, the opening 92 can be made smaller and more concealed, which improves the overall appearance of the refrigeration equipment's cabinet 90 and makes the cabinet 90 look cleaner and more high-end.

[0096] In some embodiments, when the panel 16 serves as the bottom wall of the box body 12, the periphery of the panel 16 extends toward the box cover 12 to form a side wall of the box body 12. One of the side walls of the box body 12 extends outward and beyond the edge of the panel 16 to form the entire box body 12. Therefore, along the direction from the panel 16 toward the box body 12, the projected area of ​​the panel 16 is smaller than the projected area of ​​the box body 12.

[0097] Although the opening 92 has a small area, the tilted insertion method allows the box 12 to still be smoothly inserted into the receiving cavity 91, which ensures both the convenience of installation and the aesthetics and space utilization.

[0098] Of course, in other embodiments, the control box 10 can be installed inside the housing 90 at the opening 92, which also allows the panel 16 to close the opening 92.

[0099] Combination Figure 6In some embodiments, in order to facilitate the connection between the box body 12 and the box cover 13, one of the box body 12 and the box cover 13 is provided with a first buckle 14, and the other is provided with a slot 15, with the first buckle 14 being engaged in the slot 15.

[0100] In some embodiments, when the lid 13 is to be installed on the box body 12, the first snap 14 is engaged in the slot 15, so that the lid 13 can be quickly and accurately installed on the box body 12. It is also easy to disassemble. The installation method, which does not require additional tools or complicated steps, improves work efficiency and reduces operation difficulty. It can prevent the lid 13 from loosening or falling off the box body 12 in case of accident, and ensure the stability of the lid 13 installation. Moreover, the tight cooperation between the first snap 14 and the slot 15 can effectively improve the sealing between the lid 13 and the box body 12, and can protect the lid 13 and the box body 12 from the influence of the external environment. At the same time, it can reduce the number of fasteners such as screws or rivets used, and reduce costs.

[0101] In some embodiments, when the lid 13 is to be removed from the body 12, the first latch 14 separates from the slot 15, thereby separating the lid 13 from the body 12 and improving the disassembly efficiency.

[0102] In some embodiments, the box body 12 may be provided with a first buckle 14, and the box lid 13 may be provided with a slot 15. Of course, in some other embodiments, the box lid 13 may be provided with a first buckle 14, and the box body 12 may be provided with a slot 15.

[0103] Combination Figure 13 and Figure 14 In some embodiments, to supply power to the control circuit board 20, the control circuit board 20 has a notch 21. The electronic control component also includes a power line 50. The power line 50 includes a first segment 51 and a second segment 52 connected to the first segment 51. The first segment 51 passes through the electronic control box 10 and is located inside the electronic control box 10. One end of the second segment 52 passes through the notch 21 and connects to the first segment 51, and the other end is electrically connected to the control circuit board 20. The first segment 51 and the second segment 52 are located on opposite sides of the control circuit board 20.

[0104] The first segment 51 can be connected to an external power source. The power from the external power source can be supplied to the control circuit board 20 in sequence through the first segment 51 and the second segment 52 to ensure that the circuit board 20 can work normally.

[0105] Since the control circuit board 20 has a notch 21, and the second line segment 52 passes through the notch 21 and connects with the first line segment 51, the notch 21 constrains the second line segment 52 and the first line segment 51, so that the first line segment 51 and the second line segment 52 can be routed in a specific direction. At the same time, the second line segment 52 and the first line segment 51 can be neatly fixed therein, avoiding messy wiring. There is no need to set a wiring trough in the electrical control box 10, which reduces costs.

[0106] Because the power cord 50 is flexible, when the first segment 51 passes through the notch 21 and connects with the second segment 52, it will bend at the notch 21. Under the action of tension, the first segment 51 will extend away from the control circuit board 20, so that there is a gap between the second segment 52 and the control circuit board 20 except at the connection point with the control circuit board 20 and the first segment 51. This can reduce the electromagnetic interference of the strong current of the second segment 52 and the first segment 51 on the control circuit board 20, and ensure the normal operation of the control circuit board 20.

[0107] In some embodiments, the first line segment 52 is located between the cover 13 and the control circuit board 20, and the second line segment 52 is located between the panel 16 and the control circuit board 20.

[0108] Combination Figure 12 In some embodiments, the operating element 30 includes a knob. Rotating the knob actuates the temperature adjustment trigger, thereby inputting an adjustment signal to the main control circuit. In other embodiments, the operating element 30 may include a temperature control button. Pressing the temperature control button actuates the temperature adjustment trigger, thereby inputting an adjustment signal to the main control circuit.

[0109] Combination Figure 5 and Figure 10 In some embodiments, to ensure the stability of the control circuit board 20 during installation, the housing 12 is provided with a first support member 70 and a second support member 80, both of which abut against the control circuit board 20. The first support member 70 and the second support member 80 are located on opposite sides of the control circuit board 20.

[0110] In some embodiments, when installing the control circuit board 20, the control circuit board 20 abuts against the first support member 70 and the second support member 80. The second support member 80 and the first support member 70 are respectively located on opposite sides of the control circuit board 20. By cooperating with the first support member 70, the second support member 80 and the first support member 70 apply force from opposite sides of the control circuit board 20, forming a clamping effect. This clamping force effectively prevents the control circuit board 20 from shaking or displacing, ensuring the stability and reliability of the control circuit board 20 installation.

[0111] In some embodiments, when installing the control circuit board 20, the installer only needs to place the control circuit board 20 on the first support member 70 and then press the second support member 80 onto the control circuit board 20 to fix the control circuit board 20. No additional fasteners such as screws and nuts are required, which shortens the installation time, reduces the installation difficulty, and improves work efficiency. At the same time, when the control circuit board 20 needs maintenance and replacement, it can be simply removed from the first support member 70 without damaging the surrounding structure or performing complex disassembly work, which can reduce maintenance costs and improve the maintainability of the equipment.

[0112] Combination Figure 10 In some embodiments, the first support member 70 is provided with a mounting groove 71. When installing the control circuit board 20, the control circuit board 20 can be placed in the mounting groove 71. The mounting groove 71 can provide precise positioning and guidance for the control circuit board 20, ensuring that the control circuit board 20 can be accurately aligned with its proper position during installation. This can reduce the performance degradation or failure risk caused by installation position deviation and improve stability and reliability.

[0113] In some embodiments, the first support member 70 is mounted on the housing 12, and the second support member 80 is mounted on the lid 13.

[0114] Combination Figure 9 , Figure 11 and Figure 12 In some embodiments, to prevent external water from entering the electrical control box 10 through the opening formed by the operating member 30 passing through it, the electrical control box 10 is provided with a receiving groove 17. The operating member 30 is rotatably disposed in the receiving groove 17. A water guide 60 is provided in the receiving groove 17, and a notch 61 is provided at the bottom of the water guide 60. The receiving groove 17 is located on the panel 16.

[0115] In some embodiments, when external water enters the receiving tank 17 through the gap between the operating member 30 and the tank wall of the receiving tank 17, under the action of gravity, the water will flow sequentially to the water guide member 60, the notch 61 and the receiving tank 17, and then flow out through the gap between the operating member 30 and the bottom tank wall of the receiving tank 17. This can prevent water from accumulating in the water guide member 60 and prevent water from seeping into the inside of the electrical control box 10. It can protect the electronic components, circuits or other sensitive parts inside the electrical control box 10 from damage such as moisture and corrosion, improve the waterproof performance and durability of the electrical control box 10, achieve seal-free operation, eliminate the need for rubber parts or other seals, improve the user's feel when operating the operating member 30, and eliminate the need to assemble seals, thereby improving work efficiency and reducing the difficulty of operation and error rate.

[0116] Based on the same inventive concept, this application also proposes a refrigeration device that uses the aforementioned electronic control component. The specific structure of the electronic control component is as described in the above embodiments. Since the electronic control component adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0117] Combination Figure 15 and Figure 18 In some embodiments, to enable the control box 10 to be assembled into the housing 90, the refrigeration equipment includes the housing 90 and the electrical control assembly. The housing 90 has a receiving cavity 91 and an opening 92 communicating with the receiving cavity 91. The control box 10 of the electrical control assembly passes through the opening 92 and is installed in the receiving cavity 91. The opening 92 and the operating member 30 are located on the same side of the housing 90. The main control circuit can also be used to collect the temperature of the refrigeration equipment.

[0118] The electrical control box 10 can be inserted into the receiving cavity 91 at an angle through the opening 92, so that the box body 12 can smoothly enter the receiving cavity 91, ensuring the convenience of installation and realizing the installation of the electrical control box 10.

[0119] Since the opening 92 and the operating component 30 are located on the same side of the housing 90, the housing 12 can not only enter the receiving cavity 91 through the opening 92, but the user can also directly operate the operating component 30 through the opening 92, which is convenient for the user. In addition, the user can also directly observe the display of the indicator light through the opening 92 and the light outlet 11, realizing the three uses of the opening 92. This avoids opening multiple unnecessary openings on the housing 90, thereby maintaining the streamlined appearance and cleanliness of the housing 90.

[0120] Combination Figure 7 and Figure 15 In some embodiments, in order to ensure that the panel 16 completely closes the opening 92, the edge of the panel 16 has an extension edge 161, which abuts against the inner wall of the opening 92, thereby effectively preventing external substances (such as dust, moisture, etc.) from entering the interior of the box 90 through the opening 92, ensuring the cleanliness and dryness of the interior of the box.

[0121] Combination Figure 15 In some embodiments, to facilitate operation of the operating component 30, the panel 16 of the control box 10 and the opening 92 are located on the same side of the housing 90. The operating component 30 passes through the panel 16 and is connected to the temperature adjustment trigger. The user does not need to move the position between the control box 10 and the housing 90 or change the operating direction. The user can directly operate the operating component 30 on the panel 16 through the opening 92 so that the operating component 30 can drive the temperature adjustment trigger to move. This reduces the complexity and inconvenience of the operation process and improves the user experience.

[0122] Combination Figure 16 In some embodiments, the cover 13 of the control box 10 is located inside the receiving cavity 91. The cavity wall of the receiving cavity 91 can cover the cover 13 to protect the cover 13 and prevent the cover 13 from colliding with external debris, which would cause it to separate from the box body 12 of the control box 10, thereby ensuring the safe and stable operation of the control circuit board 20 inside the control box 10.

[0123] Combination Figure 16 and Figure 17 In some embodiments, in order to ensure the stability of the electrical control box 10 installation, the electrical control box 10 is provided with a second buckle 18. The second buckle 18 abuts against the cavity wall of the receiving cavity 91. The abutment between the second buckle 18 and the cavity wall provides an additional fixing point for the electrical control box 10, thereby significantly enhancing its installation firmness in the receiving cavity 91 and reducing the risk of the electrical control box falling off or loosening due to external factors such as vibration and impact.

[0124] The second clip 18 is usually designed with an easy-to-operate structure, such as a flexible clip, which makes the installation process of the electrical control box 10 simpler and faster, without the need for additional fixing tools or materials, thus reducing installation costs and time.

[0125] Combination Figure 19 In some embodiments, the housing 90 has a recessed groove 93 communicating with the opening 92. The recessed groove 93 is located outside the receiving cavity 91. When the electrical control box 10 is installed in the housing 90, the extended edge 161 of the panel 16 is embedded in the recessed groove 93. When the second buckle 18 abuts against the cavity wall of the receiving cavity 91 and the extended edge 161 of the panel 16 abuts against the bottom of the recessed groove 93, the electrical control box 10 is limited along the installation direction of the electrical control box 10, thus ensuring the stability of the installation of the electrical control box 10.

[0126] Combination Figure 16 and Figure 17 In some embodiments, to ensure the stability of the electrical control box 10 during installation, the electrical control box 10 is provided with a limiting member 19. The limiting member 19 abuts against the inner wall of the opening 92. The abutment between the limiting member 19 and the inner wall of the opening 92 provides a precise positioning point for the electrical control box 10, ensuring the accurate position of the electrical control box 10 after installation. At the same time, this abutment also plays a fixing role, preventing the electrical control box from shifting or shaking within the receiving cavity 91, thereby ensuring the stability and reliability of the equipment.

[0127] In some embodiments, the limiting member 19 is set at an angle to the second buckle 18. Through the cooperation of the limiting member 19 and the second buckle 18, the control box 10 can be limited from two different directions. Therefore, it can more effectively prevent the control box 10 from shifting or shaking during installation or use, and improve the stability and reliability of the control box 10.

[0128] In some embodiments, the included angle between the limiting member 19 and the second buckle 18 can be set from 45° to 135°. In this embodiment, the included angle between the limiting member 19 and the second buckle 18 is 90°, that is, the limiting member 19 and the second buckle 18 are set perpendicularly, and this should not be construed as a limitation of this application.

[0129] In some embodiments, in order to facilitate the installation of the control box 10 into the receiving cavity 91, the end of the limiting member 19 facing away from the control box 10 has a slope. After the box 10 is inserted into the receiving cavity 91 at an angle through the opening 92, it is necessary to push the control box 10 into the receiving cavity 91 so that the control box 10 is fully inserted into the receiving cavity 91. At this time, the slope can be transitioned so that the control box 10 is fully inserted into the receiving cavity 91.
