Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and in particular to a control box and freezer for use in a freezer. Background Technology

[0002] As a core control component, the freezer control box undertakes key functions such as temperature regulation, lighting control, and operational status monitoring for freezers (such as wine cabinets, beverage cabinets, or cigar cabinets). Internally, it typically integrates a control board (equipped with microcontrollers, temperature sensors, signal interfaces, and other precision components) and a lighting board (for illumination). These components require multiple sets of leads for power transmission and signal interaction. However, existing control box designs generally lack constraints on the leads, allowing for arbitrary arrangement during assembly. This can lead to direct contact between the leads of the control board and the lighting board during assembly or use, potentially causing short circuits or signal interference in the components on the control board, resulting in problems such as inaccurate temperature control and lighting malfunctions. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a control box for a freezer, which uses a wire baffle to constrain the lead wires, thereby reducing the risk of the lead wires accidentally touching the control board.

[0004] The second objective of this utility model is to provide a freezer in which the lead wires inside the control box are constrained by a wire baffle, thereby reducing the probability of malfunctions inside the freezer caused by the lead wires accidentally touching the control board.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A control box for a freezer includes: The housing has a mounting cavity and a wire baffle plate. The wire baffle plate has a first end and a second end. The first end is connected to one side wall of the mounting cavity, and the second end is spaced apart from the other side wall of the mounting cavity to form a first wiring interval. The wire baffle plate divides the mounting cavity into a first cavity segment and a second cavity segment, and the first wiring interval connects the first cavity segment and the second cavity segment.

[0006] Furthermore, the box body is provided with at least two positioning holes, which are spaced apart and communicate with the first cavity segment.

[0007] Furthermore, the first cavity is also provided with two locking parts, which are located at the edge of the positioning hole.

[0008] Furthermore, the locking part includes a connecting arm and a hook, one end of the connecting arm is connected to the cavity wall of the first cavity segment, and the other end of the connecting arm is connected to the hook.

[0009] Furthermore, the second cavity section is provided with a mounting boss, which is spaced from the wire baffle to form a second wiring interval; the mounting boss is provided with a mounting opening, which penetrates the mounting boss.

[0010] Furthermore, the bottom of the box body is provided with a mounting groove that is recessed towards the mounting boss, and the mounting groove communicates with the mounting opening.

[0011] Furthermore, a transparent cover plate is provided on the mounting groove, and connecting edges are provided on both sides of the transparent cover plate, which abut against the side wall of the mounting groove.

[0012] Furthermore, the mounting groove is provided with at least two first connecting posts, which are symmetrically distributed at both ends of the mounting groove, and each of the two first connecting posts is provided with a first through hole; the transparent cover plate is provided with at least a second through hole, which is provided corresponding to the first through hole.

[0013] Furthermore, the mounting cavity is provided with a second connecting post, and the second connecting post is provided with a third through hole, which penetrates the second connecting post.

[0014] The technical solution adopted for the second objective of this utility model is: A freezer includes a cabinet body and a control box for the freezer, wherein the cabinet body has a refrigerator compartment and the control box body is installed in the refrigerator compartment.

[0015] In summary, the control box and freezer provided by this utility model have the following technical effects: the control box of the freezer is equipped with a wire baffle plate, which divides the box into two independent sections, a first section and a second section. The control board and other components such as the light board are installed in the first section and the second section respectively, so as to block the direct contact path between the two types of components and reduce the probability that the leads of other components will accidentally touch the control board due to displacement or entanglement, thereby causing short circuit or signal interference faults.

[0016] Furthermore, a first wiring interval is formed between the second end of the wire baffle and the side wall of the control box mounting cavity. In this way, the leads of various components in the box can be uniformly routed through the first wiring interval to achieve electrical connection. By constraining the arrangement path of the leads through the first wiring interval, the problem of messy stacking of leads in the box is reduced, and the risk of leads deviating from the preset path and accidentally touching the control board is further reduced.

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1, See Figures 1 to 5 This utility model discloses a control box for a freezer, including a box body 10. The box body 10 has a mounting cavity 11 and a wire baffle 12. The wire baffle 12 has a first end 121 and a second end 122. The first end 121 is connected to one side wall of the mounting cavity 11, and the second end 122 is spaced from the other side wall of the mounting cavity 11 to form a first wiring interval 13. The wire baffle 12 divides the mounting cavity 11 into a first cavity segment 111 and a second cavity segment 112. The first wiring interval 13 connects the first cavity segment 111 and the second cavity segment 112.

[0027] Based on the above structure, during assembly, the wire baffle 12 can be set at the appropriate position in the mounting cavity 11 according to the size of components such as the control board 30 and the lamp board 40, so that the space of the first cavity 111 and the second cavity 112 respectively matches the installation requirements of the corresponding components. By separating different components through the independent first cavity 111 and the second cavity 112, the components do not have direct contact after assembly, thus blocking the interference path.

[0028] Meanwhile, because the first wiring interval 13 is formed by the second end 122 of the wire baffle 12 and the side wall of the mounting cavity 11, and the width of the first wiring interval 13 is adapted to the lead wire specifications, the leads of the components in the first cavity 111 and the second cavity 112 can pass through the first wiring interval 13 in a unified manner to achieve electrical connection. At this time, the two side walls of the first wiring interval 13 (the second end 122 of the wire baffle 12 and the side wall of the mounting cavity 11) form a bidirectional limit on the lead wire, forcing the lead wire to be arranged along the preset path, effectively reducing the problem of the lead wires being randomly stacked and randomly moved in the box, and reducing the risk of the lead wires going off the path and accidentally touching the components.

[0029] When the control box of this embodiment is applied to a refrigerator (such as a wine cabinet, beverage cabinet or cigar cabinet or other refrigeration equipment), the control board 30 can be installed in the first cavity section 111, and the lamp board 40 or other auxiliary components (such as power modules) can be installed in the second cavity section 112. At this time, the wire baffle 12 can directly block the direct contact between the lamp board 40 and other components and the control board 30, reduce the risk of accidentally touching the control board 30 due to the displacement of the lamp board 40, and at the same time reduce the impact of electromagnetic interference generated by the lead wire of the lamp board 40 on the signal transmission of the control board 30, thereby improving the stability of the internal control system and lighting function of the refrigerator.

[0030] Furthermore, the leads between the control board 30, the lamp board 40, and the auxiliary components can all be electrically connected by extending into the corresponding cavity sections through the first wiring interval 13. The sidewall of the first wiring interval 13 can prevent lateral displacement of the leads, further constraining the lead layout path and forcing the leads to be arranged along a preset path, effectively reducing the probability of accidental contact with the control board 30 or other components due to random displacement of the leads within the box. At the same time, the orderly lead layout also facilitates quick identification of the components corresponding to the leads during later maintenance, reducing maintenance difficulty and improving maintenance efficiency.

[0031] It should be noted that the wire baffle 12 in this embodiment can be integrally formed inside the box body 10, or it can be connected to the box body 10 by gluing or welding.

[0032] Furthermore, the box body 10 is provided with at least two positioning holes 14, which are spaced apart and communicate with the first cavity section 111.

[0033] Specifically, during assembly, two positioning holes 14 are set on the outer wall of the first cavity 111 and are connected to the first cavity 111. The two positioning holes 14 are arranged at intervals along the component mounting direction (the interval distance matches the spacing of the mounting holes on the control board 30). The diameter of the positioning holes 14 can be set according to the positioning structure (such as positioning post) of the component (such as control board 30) in the first cavity 111 or the specifications of the connecting parts to be assembled (such as self-tapping screws, positioning pins). In this way, if the control board 30 has a positioning post, the positioning post can be directly inserted into the positioning hole 14 to achieve rapid pre-positioning of the component and reduce the problem of the control board 30 shifting during assembly.

[0034] Alternatively, the control board 30 can be rigidly fixed to the box 10 by inserting connectors (such as self-tapping screws or rivets) through the positioning holes 14. For example, self-tapping screws can be inserted into the mounting holes of the control board 30 after passing through the positioning holes 14, so that the control board 30 fits tightly against the side wall of the box 10, thereby improving the stability of the connection between the control board 30 and the box 10.

[0035] Furthermore, the first cavity 111 is also provided with two snap-fit ​​parts 15, which are located at the edge of the positioning hole 14.

[0036] Specifically, after the components (such as the control board 30) in the first cavity 111 are initially fixed through the positioning holes 14, for example, the positioning pins of the control board 30 are inserted into the positioning holes 14 to achieve pre-positioning, or the screws are inserted through the positioning holes 14 to achieve initial locking, although the control board 30 is initially fixed, it may become slightly loose due to positioning gaps, screws not being fully locked, or long-term vibration. Therefore, in this embodiment, the snap-fit ​​part 15 can further lock the components a second time, improving the stability of the connection between the components and the housing 10 and reducing the risk of lead wires being pulled or solder joints falling off due to loose components.

[0037] It should be noted that the snap-fit ​​part 15 in this embodiment can be a hook-shaped buckle with a barb structure at the end. When the control board 30 is pre-fixed through the positioning hole 14, the barb can hook onto the reserved slot on the edge of the control board 30 or the gap of the component pin, forming an irreversible limit to lock the control board 30 a second time. When disassembling, only a force in a specific direction needs to be applied to disassemble it, which not only ensures the stability of the fixation but also takes into account the needs of later maintenance.

[0038] Of course, the snap-fit ​​part 15 can also be a slot located at the edge of the positioning hole 14. The opening of the slot faces the installation direction of the control board 30, and the width of the slot is adapted to the thickness of the control board 30. At the same time, small anti-slip protrusions are provided on the inner side wall of the slot. During assembly, the control board 30 slides in along the opening of the slot, and the anti-slip protrusions embed into the small textures or reserved slots on the surface of the control board 30, which not only achieves quick positioning but also reduces the problem of lateral movement of the control board 30.

[0039] Preferably, the latching part 15 includes a connecting arm 151 and a latch 152. One end of the connecting arm 151 is connected to the cavity wall of the first cavity segment 111, and the other end of the connecting arm 151 is connected to the latch 152. During assembly, one end of the connecting arm 151 is fixedly connected to the cavity wall of the first cavity segment 111 (near the positioning hole 14) by integral injection molding or welding, and the length of the connecting arm 151 needs to be adapted to the installation depth of the control plate 30 to ensure that the latch 152 can effectively contact the control plate 30; the other end of the connecting arm 151 is integrally formed with the latch 152. During assembly, after the control plate 30 is pre-fixed through the positioning hole 14, it is gently pushed towards the connecting arm 151. The connecting arm 151 is compressed and undergoes elastic deformation. The latch 152 swings with the connecting arm 151 and hooks the reserved step on the edge of the control plate 30. After the control plate 30 is in place, the connecting arm 151 returns to its original shape, and the latch 152 presses tightly against the control plate 30 through its own elasticity, forming a stable limit.

[0040] Furthermore, the second cavity section 112 is provided with a mounting boss 16, which forms a second wiring interval 17 with the wire baffle plate 12. The mounting boss 16 is provided with a mounting port 161, which penetrates the mounting boss 16.

[0041] Specifically, during assembly, the mounting protrusions can be used to mount the lamp plate 40, which is then fixed to the mounting opening 161 with screws. The mounting protrusions 16 provide a rigid support surface for the lamp plate 40. Compared to the lamp plate 40 being directly fixed to the cavity wall of the mounting cavity 11, the support of the mounting protrusions 16 can distribute the force on the lamp plate 40 and reduce the probability of the screws of the lamp plate 40 loosening due to vibration.

[0042] Furthermore, the second wiring interval 17 formed by the mounting boss 16 and the wire baffle 12 provides an installation channel for the power and signal leads of the lamp board 40. Thus, the leads of the lamp board 40 can pass through the second wiring interval 17, and then through the first wiring interval 13 into the first cavity 111 to connect with the control board 30 or the power module. This makes the wiring of the lamp board 40 more orderly, further reducing the messy stacking of the lamp board 40 leads in the second cavity 112. This reduces the risk of insulation layer damage caused by friction between the leads and other components (such as the power module) in the second cavity 112, and prevents the leads from deviating from the path and crossing the wire baffle 12, accidentally contacting the control board 30 in the first cavity 111. This reduces the probability of short circuit faults and signal interference from the control board 30, ensuring the overall stable operation of the control box.

[0043] Furthermore, the bottom of the housing 10 is provided with a mounting groove 18 that is recessed toward the mounting boss 16, and the mounting groove 18 communicates with the mounting opening 161.

[0044] Specifically, after the lamp board 40 is fixed to the mounting boss 16, the lamp beads (such as LED beads) on the lamp board 40 are precisely aligned with the mounting opening 161. When the lamp board 40 is lit, the light mainly enters the mounting groove 18 below vertically through the mounting opening 161. At this time, the side wall of the mounting groove 18 can effectively block the light from scattering to the side (i.e., in the direction parallel to the lamp board 40), reducing the light scattering from the side of the control box, and forcing the light to be concentrated and emitted to the bottom along the axial direction of the mounting groove 18 (perpendicular to the lamp board 40), so that the light distribution of the lamp board 40 is more concentrated.

[0045] More specifically, a transparent cover plate 20 is provided on the mounting groove 18, and connecting edges 21 are provided on both sides of the transparent cover plate 20. The connecting edges 21 abut against the side wall of the mounting groove 18. During assembly, the transparent cover plate 20 is aligned with the opening of the mounting groove 18 and gently pressed to insert it into the mounting groove 18. At this time, the connecting edges 21 will form a slight interference fit with the side wall of the mounting groove 18, and a tight fit is achieved by utilizing the elasticity of the plastic material, and fixation can be completed without additional fasteners. Through the tight abutment of the transparent cover plate 20 with the side wall of the groove via the connecting edges 21, a sealing barrier can be formed between the mounting opening 161 and the groove, thereby reducing the entry of condensate and dust from the refrigerator into the control box, and reducing the problems of short circuits and aging of the light board 40 and lead wires due to moisture or dust accumulation.

[0046] It should be noted that the transparent cover 20 can be made of materials such as glass or acrylic sheet.

[0047] Furthermore, at least two first connecting posts 181 are provided in the mounting groove 18. The two first connecting posts 181 are symmetrically distributed at both ends of the mounting groove 18. The two first connecting posts 181 are provided with first through holes 1811. The transparent cover plate 20 is provided with second through holes 22. The second through holes 22 are corresponding to the first through holes 1811.

[0048] Specifically, during assembly, the transparent cover plate 20 is embedded into the mounting groove 18 until the connecting edge 21 abuts against the mounting groove 18. At this time, the second through hole 22 on the transparent cover plate 20 corresponds to the first through hole 1811 on the first connecting post 181. Then, the operator can insert the connector (such as screw or bolt) into the second through hole 22 and the first through hole 1811 to lock the transparent cover plate 20, thereby reducing the risk of the transparent cover plate 20 falling out of the mounting groove 18 and improving the stability of the entire structure.

[0049] It should be noted that the number of second through holes 22 can be set to two, three or more, depending on the number of first through holes 1811.

[0050] More specifically, a second connecting post 19 is provided in the mounting cavity 11, and a third through hole 191 is provided on the second connecting post 19. The third through hole 191 passes through the second connecting post 19. When the box body 10 is connected to other external structures such as a freezer, a connector (such as a screw or bolt) can be passed through the third through hole 191 to connect the box body 10 to the external structure.

[0051] Example 2, See Figures 6 to 8 A freezer includes a cabinet body 50 and a control box for the freezer. The cabinet body 50 has a refrigerator compartment 51, and the box body 10 is installed in the refrigerator compartment 51.

[0052] Specifically, during assembly, the control board 30 and the lamp board 40 are first installed in the first cavity 111 and the second cavity 112, respectively. Then, the box 10 is locked to the top of the refrigerator compartment 51 using screws or bolts. The top of the box 10 is aligned with the wiring hole 511 on the cabinet 50 so that the wires can be threaded through the wiring hole 511 into the box 10. The side of the mounting groove 18 faces the inside of the refrigerator compartment 51 so that the lamp board 40 inside the control box can illuminate the refrigerator compartment 51, making it easier for users to retrieve items inside the cabinet. Since the wire baffle 12 inside the box 10 can directly prevent the lamp board 40 and other components from directly contacting the control board 30, the risk of accidentally touching the control board 30 due to lamp board 40 displacement can be reduced. At the same time, the electromagnetic interference generated by the lamp board 40 leads can be reduced to affect the signal transmission of the control board 30, thereby improving the stability of the internal control system and lighting function of the refrigerator.

[0053] Furthermore, the leads between the control board 30, the lamp board 40, and the auxiliary components can all be electrically connected by extending into the corresponding cavity sections through the first wiring interval 13. The sidewall of the first wiring interval 13 can prevent lateral displacement of the leads, further constraining the lead layout path and forcing the leads to be arranged along a preset path, effectively reducing the probability of accidental contact with the control board 30 or other components due to random displacement of the leads within the box. At the same time, the orderly lead layout also facilitates quick identification of the components corresponding to the leads during later maintenance, reducing maintenance difficulty and improving maintenance efficiency.

[0054] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
