Description

Technical Field

[0001] This utility model belongs to the field of electrical equipment technology, and in particular relates to a freezer. Background Technology

[0002] As the new national standard for energy efficiency upgrades is being implemented, fixed-frequency products in the industry will gradually shift to variable-frequency products. Low-cost main inverter display technology is widely used in air-cooled and direct-cooled products. As the carrier of the control board, the controller box must be able to ensure that it can be adapted to the wiring methods of main control boards with different functions to reduce costs.

[0003] Different control boards have different external wiring harness locations. The existing control boards and controller boxes are in a one-to-one correspondence. As the types of control boards increase, the types of control boxes also increase accordingly. This requires the design and production of different manufacturing molds, which increases the cost.

[0004] In addition, the cable outlet of a typical control box is located on the cover, and there is no pre-fixing structure for the cable harness on the cable outlet. When installing the cover, the control board cable harness must be constantly combed. This assembly method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0005] The purpose of this utility model is to provide a freezer that solves the problems in the prior art, such as the controller box not being interchangeable when the controller board is different, high manufacturing and processing costs, and the wiring holes being set on the cover, which makes wire harness management time-consuming and laborious, and low assembly efficiency.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: This utility model proposes a freezer, which includes: Cabinet; The controller includes a housing, a cover, and an electronic control board. The cover is detachably connected to the housing, and a mounting cavity is formed between the housing and the cover. The electronic control board is disposed within the mounting cavity.

The support part has a wire passing slot, and a sealing valve plate is detachably connected in the wire passing slot. Multiple connecting dotted parts are provided between the sealing valve plate and the wire passing slot.

[0007] In some embodiments of this application, the bottom of the wire passage is arc-shaped, and the two sides of the wire passage have relatively extended pre-fixed portions.

[0008] The bottom of the wire guide slot is rounded, which can better position the wire harness and avoid damage to the wire harness due to force. The pre-fixing part can play a role in the initial positioning of the wire harness in the wire guide slot, which facilitates the subsequent assembly of the box cover.

[0009] In some embodiments of this application, a buckle portion is provided on the outer wall of the box body, and a snap-fit ​​portion is provided at the corresponding position of the box lid. The buckle portion is detachably connected to the snap-fit ​​portion to achieve snap-fit ​​between the box lid and the box body.

[0010] The lid and body are connected and fixed by a snap-fit ​​method, which helps to reduce the use of fasteners and the machining of fastening holes, provides better sealing, and is easy to assemble and disassemble.

[0011] In some embodiments of this application, the front panel of the cabinet is provided with an installation port, the controller is fixed on the installation port, a water-blocking part extending inward is formed on the peripheral wall of the installation port, a fixed base plate is provided on the box body, the outer peripheral dimension of the fixed base plate is larger than the water-blocking part and smaller than the installation port, and the fixed base plate is installed on the outside of the water-blocking part.

[0012] The water-blocking part uses the surface tension of water to prevent water from the outside of the cabinet from entering the cabinet and controller through the gap between the installation port and the controller, thus achieving a waterproof effect. The water-blocking part is connected to the fixed base plate, and the connection and fixation between the controller and the cabinet is achieved by the fixing buckle on the outer wall of the box, which helps to improve assembly efficiency.

[0013] In some embodiments of this application, an upwardly extending baffle rib is provided on the top wall of the box body. The baffle rib is located inside the water-blocking part and blocks liquid entering from the installation port.

[0014] The baffle ribs serve as a second layer of waterproofing, further blocking water that may enter the cabinet through the gap between the mounting opening and the controller, preventing it from continuing to flow along the outer wall of the cabinet into the mounting cavity.

[0015] In some embodiments of this application, a hydrophobic slope with a high center and low sides is formed on the top wall between the partition rib and the fixed base plate. The hydrophobic slope is used to discharge liquid entering from the installation port from both sides.

[0016] Water entering the cabinet through the gap between the mounting port and the controller is drained to both sides by the drainage slope, preventing water accumulation.

[0017] In some embodiments of this application, a mating recess is provided on the side wall of the box body, a downwardly extending connecting edge is formed on the box cover, a snap-fit ​​portion is formed on the connecting edge, and a latching portion is formed on the side wall of the mating recess.

[0019] In some embodiments of this application, the lid is provided with a clearance groove, and the clearance groove corresponds one-to-one with the position of the support portion.

[0020] An outer partition is provided on the outer side of the support part, and a middle partition is provided between adjacent wire passage slots on the same support part.

[0021] The outer partition further protects the cable tray opening, while the middle partition improves the structural strength of the support and also serves to separate the cable harnesses.

[0022] This application also proposes a freezer, which includes: Cabinet; The controller includes a housing, a cover, and an electronic control board. The cover is detachably connected to the housing, and a mounting cavity is formed between the housing and the cover. The electronic control board is disposed within the mounting cavity. The box body is provided with multiple wire passing parts, each wire passing part having a wire passing slot. A sealing valve is connected to the wire passing slot, and the sealing valve is configured to remove the sealing valve corresponding to the wire passing slot before a wire harness passes through.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are: The freezer involved in this application has a wiring section on the box body. The wiring section includes a support part located on the periphery of the box body and extending towards the mounting cavity. The wiring slot is located on the support part, and the wiring slot is sealed by a sealing valve to prevent external water from entering the mounting cavity and affecting the operation of the control board. When connecting external wiring harnesses to the control board, the sealing valve at the corresponding position is first removed to allow the external wiring harnesses to pass through.

[0033] refer to Figures 1-5 This utility model proposes a freezer, which includes a cabinet body 100 and a controller 200 installed inside the cabinet body 100. Specifically, the controller 200 is installed inside the front panel 110 of the cabinet body 100.

[0034] The controller 200 includes a housing 210, a cover 220, and an electronic control board 230. The cover 220 is detachably connected to the housing 210, and an installation cavity is formed between the housing 210 and the cover 220. The electronic control board 230 is disposed in the installation cavity.

[0035] To improve the versatility of the controller 200, that is, to allow different control boards 230 to be assembled in the same mounting cavity formed by the housing 210 and the cover 220, this application provides multiple wiring sections on the housing 210 to meet the wiring requirements of different control boards 230.

[0036] Combination Figures 6-7 Each wire-passing part includes a support part 211 extending towards the mounting cavity. A wire-passing slot is provided on the support part 211. A sealing valve plate 215 is detachably connected in the wire-passing slot. Multiple connecting dotted parts 2151 are provided between the sealing valve plate 215 and the wire-passing slot.

[0037] The connection 2151 between the sealing valve plate 215 and the wire passage groove is provided with at least two intervals along the periphery of the wire passage groove. Depending on the size of the wire passage groove, three or more intervals may also be provided to improve the connection strength and reduce the connection gap.

[0038] To facilitate the disassembly of the sealing valve plate 215, an operating protrusion is designed to be formed on the outer surface of the sealing valve plate 215. The operating protrusion protrudes a certain distance from the outer surface of the sealing valve plate 215, making it convenient for the user to hold the sealing valve plate 215 when disassembling it.

[0039] In other words, the support part 211 is perpendicular to the side wall of the box 210, and the support part 211 is provided with a wire passage slot for the wire harness to pass through.

[0040] The sealing valve plate 215 is used to seal the wire passage opening. That is, when the wire harness connected to the control board 230 does not pass through the wire passage opening, the wire passage opening is sealed by the sealing valve plate 215 to prevent foreign objects, dust or water from entering the installation cavity.

[0041] For example, but not limited to, along the length of the box 210, a plurality of support portions 211 are provided at intervals on both sides of the box 210, and each support portion 211 is provided with at least one wire passage slot.

[0042] In order to further protect the limiting slot and limit the wire harness, an outer partition 218 is set on the outside of the limiting slot, and a middle partition 219 is set between two adjacent wire passing slots of the same support part 211.

[0043] The outer partition 218 further protects the wire passage openings, preventing water or foreign objects from entering. The middle partition 219 separates the wire harnesses that will pass through the two wire passage openings, making them easy to distinguish.

[0044] In some embodiments of this application, the bottom of the wire passage is arc-shaped, and the two sides of the wire passage opening are respectively provided with relatively extended pre-fixing portions 2111.

[0045] The bottom of the wire passage slot is rounded, which can better position the wire harness and avoid damage to the wire harness due to force. The pre-fixing part 2111 can play a role in the initial positioning of the wire harness in the wire passage slot, which facilitates the subsequent assembly of the cover 220.

[0046] refer to Figure 6 , Figure 8 In some embodiments of this application, a buckle portion 214 is provided on the outer wall of the box body 210, and a snap-fit ​​portion 222 is provided at the corresponding position of the box cover 220. The buckle portion 214 is detachably connected to the snap-fit ​​portion 222 to achieve snap-fit ​​between the box cover 220 and the box body 210.

[0047] The snap-fit ​​portion 214 and the snap-fit ​​portion 222 are spaced apart on the periphery of the box body 210 and the box cover 220 so that the box body 210 and the box cover 220 are well connected in all directions.

[0048] The cover 220 and the body 210 are connected and fixed by a snap-fit ​​method, which helps to reduce the use of fasteners and the processing of fastening holes, improves the sealing performance, and makes it easy to install and remove.

[0049] In some embodiments of this application, the cover 220 is provided with a clearance groove 223, and the clearance groove 223 corresponds one-to-one with the position of the support 211 to facilitate the passage of the wire harness.

[0050] In some embodiments of this application, a support rib 217 is provided on the inner wall of the box 210. The support rib 217 is provided at intervals along the periphery of the box 210, and the electronic control board 230 is supported on the support rib 217.

[0051] Specifically, each support rib 217 has a support surface with a uniform height, and the electrical control board 230 is mounted on the support surface.

[0052] The bottom of the housing 210 has a fixed protrusion, and a threaded hole is formed inside the fixed protrusion. The control board 230 is detachably connected to the fixed protrusion by fasteners.

[0053] Specifically, the control board 230 is provided with a connection hole, and the fastener passes through the connection hole and is threaded into the threaded hole of the fixing protrusion to fix the control board 230.

[0054] In some embodiments of this application, a mating recess 212 is provided on the side wall of the box body 210, a downwardly extending connecting edge 221 is formed on the box cover 220, a snap-fit ​​part 222 is formed on the connecting edge 221, and a latching part 214 is formed on the side wall of the mating recess 212.

[0055] The length of the recess 212 along the depth direction of the mounting cavity is matched with the length of the connecting edge 221. That is, when the cover 220 is connected to the box body 210, the bottom of the connecting edge 221 contacts the bottom of the recess 212, so as to improve the sealing between the cover 220 and the box body 210.

[0056] In some other embodiments, in order to facilitate the removal of the cover 220, an operation recess 216 is provided at the bottom of the mating recess 212. The operation recess 216 corresponds one-to-one with the connecting edge 221. When removing the cover 220, the user expands the connecting edge outward from the operation recess 216 position so that the latching part 214 and the snap-fit ​​part 222 are separated.

[0057] refer to Figures 9-11 In some embodiments of this application, the front panel 110 of the cabinet 100 is provided with an installation port 120, and the controller 200 is fixed to the installation port 120.

[0058] A water-blocking portion 130 extending inward is formed on the peripheral wall of the mounting port 120. The water-blocking portion 130 specifically includes a water-blocking horizontal portion 131 perpendicular to the front plate 110 and a water-blocking vertical portion 132 vertically disposed inside the water-blocking horizontal portion 131.

[0059] A fixed base plate is provided on the box body 210. The peripheral dimension of the fixed base plate is larger than the outer wall of the box body 210, and the outer peripheral dimension of the fixed base plate is larger than the water-blocking part 130 and smaller than the mounting opening 120. The fixed base plate is installed on the outside of the water-blocking part 130.

[0060] Specifically, the outer perimeter of the fixed base plate is larger than the opening size on the water-retaining upright 132. During installation, the controller 200 is assembled into the cabinet 100 from the mounting port 120, and the fixed base plate is located on the outside of the water-retaining upright 132.

[0061] The water-blocking part 130 serves as the first waterproof structure. It uses the surface tension of water to prevent water from outside the cabinet 100 from entering the cabinet 100 and the controller 200 through the gap between the mounting port 120 and the controller 200, thus achieving a waterproof effect. The water-blocking part 130 is connected to the fixed base plate, and the connection and fixation between the controller 200 and the cabinet 100 are achieved through the fixing buckles on the outer wall of the box 210, which helps to improve assembly efficiency.

[0062] In the defined installation state, the upper outer wall of the box 210 is the top wall, and the lower outer wall is the bottom wall. The top wall of the box 210 is provided with an abutment part 201, and the bottom wall of the box 210 is provided with a positioning protrusion 202.

[0063] A positioning gap is formed between the positioning protrusion 202 and the fixed base plate. During installation, the cover 220 and the body 210 of the controller 200 are tilted into the cabinet 100 from the mounting port 120, and the lower edge of the water-blocking upright 132 is engaged between the positioning protrusion 202 and the fixed base plate.

[0064] The abutting part 201 has an abutting end extending toward the fixed base plate. As it is installed, the abutting end is retracted toward the top wall of the box 210 until the abutting end is completely moved to the inside of the water-blocking upright part 132. Under the action of its own restoring force, the abutting end expands outward to the inside of the water-blocking upright part 132, and the upper edge of the water-blocking upright part 132 is engaged between the abutting part 201 and the fixed base plate.

[0065] In some embodiments of this application, in order to prevent external water from entering the cabinet 100 and the controller 200, an upwardly extending baffle rib 213 is provided on the top wall of the box 210. The baffle rib 213 is located inside the water-blocking part 130 and blocks the liquid entering from the mounting port 120.

[0066] The baffle rib 213 serves as a second waterproof structure, further blocking water that may enter the cabinet 100 through the gap between the mounting port 120 and the controller 200, preventing it from continuing to flow along the outer wall of the box 210 into the mounting cavity.

[0067] In some embodiments of this application, a hydrophobic slope with a high center and low sides is formed on the top wall between the partition rib 213 and the fixed base plate. The hydrophobic slope is used to discharge liquid entering from the mounting port 120 from both sides.

[0068] Water entering the cabinet 100 through the gap between the mounting port 120 and the controller 200 is drained to both sides by the drainage slope to prevent water accumulation.

[0069] This application also proposes a freezer, which includes: Cabinet 100; The controller 200 includes a housing 210, a cover 220, and an electronic control board 230. The cover 220 is detachably connected to the housing 210, and an installation cavity is formed between the housing 210 and the cover 220. The electronic control board 230 is disposed in the installation cavity. The housing 210 has multiple wire passing sections, each with a wire passing slot. A sealing valve 215 is connected to the wire passing slot. The sealing valve 215 is configured to remove the corresponding sealing valve 215 from the wire passing slot before a wire harness passes through.

[0070] The design of the cable tray can adopt the following methods, or a combination of several of them.

[0071] Method 1: The wire passage slot is set on the side wall of the box 210 (not shown), with the opening of the wire passage slot facing upward, for the wire harness connected to the external control board 230 to pass through.

[0072] In order to restrict the wire harness, the opening of the wire passage is designed to be recessed to pre-fix the wire harness.

[0073] During installation, after the wiring of the control board 230 is completed, the wire harness is passed out through the wire channel, and then the cover 220 is closed.

[0074] A sealing valve plate 215 is detachably connected inside the wire passage slot, and multiple connecting dotted parts 2151 are provided between the sealing valve plate 215 and the wire passage slot.

[0075] The connection 2151 between the sealing valve plate 215 and the wire passage groove is provided with at least two intervals along the periphery of the wire passage groove. Depending on the size of the wire passage groove, three or more intervals may also be provided to improve the connection strength and reduce the connection gap.

[0076] Method 2: Each wire-passing part includes a support part 211 extending towards the mounting cavity, and a wire-passing slot is provided on the support part 211.

[0077] A sealing valve plate 215 is detachably connected inside the wire passage slot, and multiple connecting dotted parts 2151 are provided between the sealing valve plate 215 and the wire passage slot.

[0078] To facilitate the disassembly of the sealing valve plate 215, an operating protrusion is designed to be formed on the outer surface of the sealing valve plate 215. The operating protrusion protrudes a certain distance from the outer surface of the sealing valve plate 215, making it convenient for the user to hold the sealing valve plate 215 when disassembling it.

[0079] In other words, the support part 211 is perpendicular to the side wall of the box 210, and the support part 211 is provided with a wire passage slot for the wire harness to pass through.

[0080] The sealing valve plate 215 is used to seal the wire passage opening. That is, when the wire harness connected to the control board 230 does not pass through the wire passage opening, the wire passage opening is sealed by the sealing valve plate 215 to prevent foreign objects, dust or water from entering the installation cavity.

[0081] In order to further protect the limiting slot and limit the wire harness, an outer partition 218 is set on the outside of the limiting slot, and a middle partition 219 is set between two adjacent wire passing slots of the same support part 211.

[0082] The outer partition 218 further protects the wire passage openings, preventing water or foreign objects from entering. The middle partition 219 separates the wire harnesses that will pass through the two wire passage openings, making them easy to distinguish.

[0083] Method 3, based on Method 2, has an arc-shaped bottom for the wire passage slot, and pre-fixed parts 2111 that extend relatively on both sides of the wire passage slot opening.

[0084] The bottom of the wire passage slot is rounded, which can better position the wire harness and avoid damage to the wire harness due to force. The pre-fixing part 2111 can play a role in the initial positioning of the wire harness in the wire passage slot, which facilitates the subsequent assembly of the cover 220.

[0085] In some embodiments of this application, a buckle portion 214 is provided on the outer wall of the box body 210, and a corresponding snap-fit ​​portion 222 is provided on the box cover 220. The buckle portion 214 is detachably connected to the snap-fit ​​portion 222 to achieve snap-fit ​​between the box cover 220 and the box body 210.

[0086] The cover 220 and the body 210 are connected and fixed by a snap-fit ​​method, which helps to reduce the use of fasteners and the processing of fastening holes, improves the sealing performance, and makes it easy to install and remove.

[0087] In some embodiments of this application, the cover 220 is provided with a clearance groove 223, and the clearance groove 223 corresponds one-to-one with the position of the support 211 to facilitate the passage of the wire harness.

[0088] In some embodiments of this application, a support rib 217 is provided on the inner wall of the box 210. The support rib 217 is provided at intervals along the periphery of the box 210, and the electronic control board 230 is supported on the support rib 217.

[0089] Specifically, each support rib 217 has a support surface with a uniform height, and the electrical control board 230 is mounted on the support surface.

[0091] The length of the recess 212 along the depth direction of the mounting cavity is matched with the length of the connecting edge 221. That is, when the cover 220 is connected to the box body 210, the bottom of the connecting edge 221 contacts the bottom of the recess 212, so as to improve the sealing between the cover 220 and the box body 210.

[0092] In some other embodiments, in order to facilitate the removal of the cover 220, an operation recess 216 is provided at the bottom of the mating recess 212. The operation recess 216 corresponds one-to-one with the connecting edge 221. When removing the cover 220, the user expands the connecting edge outward from the operation recess 216 position so that the latching part 214 and the snap-fit ​​part 222 are separated.

[0093] Compared with the prior art, the advantages and positive effects of this utility model are: The freezer involved in this application has a wiring section on the box body 210. The wiring section includes a support part 211 located on the periphery of the box body 210 and extending towards the mounting cavity.
