Description

Technical Field

[0001] This utility model relates to the field of refrigeration electrical technology, and mainly to a refrigeration device. Background Technology

[0002] Refrigeration equipment is a device that maintains a constant low temperature to store goods, and it is widely used in modern life and industrial production. For example, freezers have many advantages such as large storage space and high cost performance, and are widely used in shopping malls or other places for food refrigeration.

[0003] The bottom of a freezer usually has a compressor chamber, which contains refrigeration components such as a compressor and a condenser. Since both the compressor and the condenser need to dissipate heat, a vent is provided at the back of the freezer that connects to the compressor chamber to dissipate heat.

[0004] The compressor compartment is also equipped with a junction box, which is used to connect to the compressor and the electrical control inside the freezer. Generally, the wiring holes of the junction box are located on the side wall of the junction box. When the freezer is placed outdoors and encounters thunderstorms, moisture can easily enter the interior of the junction box through the wiring holes, damaging the junction box and causing safety problems. Utility Model Content

[0005] Based on existing technology, a refrigeration device is provided to improve the waterproofing of the junction box inside the compressor chamber and enhance the safety of the refrigeration device.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a compressor chamber is provided at the bottom of the housing, and an installation port is provided on the side wall of the compressor chamber; a junction box is fixed at the installation port, the junction box has an installation cavity, and a waterproof groove is recessed on the outer side wall of the junction box near the installation port, the groove wall of the waterproof groove has a communicating hole, the communicating hole connecting the waterproof groove and the installation cavity; a wiring cover is inserted through the installation port and located within the waterproof groove, the wiring cover including: a through portion, the through portion being inserted through the installation port; and a connecting wall surrounding the installation port. The through-hole is located near the edge of the waterproof groove, and the connecting wall is attached to the peripheral edge of the mounting opening. A baffle plate extends from the end of the connecting wall away from the through-hole towards the groove wall of the waterproof groove, and the baffle plate is located above the mounting opening. A terminal block is inserted into the through-hole, with its inner end located inside the waterproof groove and exposed outside the connecting hole, and its outer end extending outside the mounting opening. The end of the baffle plate away from the connecting wall abuts against the groove wall of the waterproof groove, and the baffle plate is located above the connecting hole.

[0008] The above technical solution has the following advantages or beneficial effects: A waterproof groove is recessed on the outer wall of the junction box near the mounting opening. When the junction box is installed at the mounting opening, an independent waterproof space is formed between the side wall of the waterproof groove and the side wall of the compressor chamber. The waterproof groove can buffer and block moisture, preventing most of the moisture from entering the junction box. Furthermore, the junction cover passes through the mounting opening via a through-hole, and the connecting wall is arranged around the periphery of the mounting opening and fits against its periphery, thereby improving the seal between the junction cover and the side wall of the mounting opening and greatly reducing the risk of moisture entering the mounting opening through the gap between the junction cover and the side wall of the compressor chamber. Furthermore, the baffle extends from the end of the connecting wall away from the through-hole towards the wall of the waterproof groove and is located above the installation opening. In this way, the baffle can shield the wire harness and terminals installed below. Even if a small amount of moisture enters the waterproof groove, the rainwater will be blocked by the baffle and will not drip directly onto the installation opening and connecting hole. This prevents rainwater from entering the junction box through these parts and flowing to the wire harness and terminals, thus avoiding safety problems such as short circuits and leakage caused by moisture intrusion into the terminals. This improves the safety and reliability of the junction box in the compressor room.

[0009] In some embodiments of this application, a cooling device is provided, wherein the top of the baffle is provided with a first inclined wall and a second inclined wall, the first inclined wall is connected to one end of the second inclined wall, the other end of the first inclined wall extends downward at an incline away from the second inclined wall and extends to one side of the mounting port; the other end of the second inclined wall extends downward at an incline away from the first inclined wall and extends to the other side of the mounting port.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a first inclined wall and a second inclined wall at the top of the baffle, the first inclined wall extends downward at an angle away from the second inclined wall, and the second inclined wall extends downward at an angle away from the first inclined wall, so that the connection end of the first inclined wall and the second inclined wall can form the highest point of the baffle, and both ends are inclined downward towards the sides of the installation opening, so that water vapor can flow naturally along the slope of the inclined wall no matter which direction it drips from the baffle.

[0011] In some embodiments of this application, a refrigeration device is provided. The waterproof groove has a first groove sidewall and a second groove sidewall arranged opposite to each other. The first groove sidewall is spaced apart from the left side of the wiring cover to form a first gap. The first gap extends along the height direction of the waterproof groove, and the upper end of the first gap extends upward to the end of the first inclined wall away from the second inclined wall. The second groove sidewall is spaced apart from the right side of the wiring cover to form a second gap. The second gap extends along the height direction of the waterproof groove, and the upper end of the second gap extends upward to the end of the second inclined wall away from the first inclined wall.

[0012] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the upper end of the first gap can extend to the end of the first inclined wall away from the second inclined wall, and the water vapor flowing downward along the first inclined wall can directly enter the first gap, and the water vapor entering the first gap can continue to flow downward along its height extension direction; the upper end of the second gap can extend to the end of the second inclined wall away from the first inclined wall, and the water vapor flowing downward along the second inclined wall can directly enter the second gap, and the water vapor entering the second gap can continue to flow downward along its height extension direction, which can effectively prevent water vapor from accumulating at the top edge of the wiring cover.

[0013] In some embodiments of this application, a cooling device is provided, wherein the top wall of the junction box forms a flow guide wall, the flow guide wall being located above the waterproof groove; the junction box has a first outer side wall and a second outer side wall disposed opposite to each other, the flow guide wall being arranged to extend downward at an angle toward the first outer side wall or the flow guide wall being arranged to extend downward at an angle toward the second outer side wall.

[0014] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by setting the guide wall to extend downward at an angle toward the first outer wall or to extend downward at an angle toward the second outer wall, rainwater can flow downward at an angle along the surface of the guide wall and flow to the outside of the junction box. In this way, water vapor can flow in a direction away from the waterproof groove, avoiding the risk of leakage from the top wall of the junction box to the waterproof groove below due to excessive water accumulation. This is beneficial to keep the electrical components in the junction box and the wiring terminals located in the waterproof groove in a dry working environment.

[0015] In some embodiments of this application, a cooling device is provided, wherein the flow guide wall includes a third inclined wall and a fourth inclined wall, one end of the third inclined wall is connected to one end of the fourth inclined wall, the other end of the third inclined wall extends downward at an angle away from the fourth inclined wall and extends to one side of the first outer wall; the other end of the fourth inclined wall extends downward at an angle away from the third inclined wall and extends to one side of the second outer wall.

In this way, the connection end of the third inclined wall and the fourth inclined wall can form the highest point of the guide wall, and both ends are inclined downward towards the sides of the junction box, so that water vapor can flow naturally downward along the slope of the third inclined wall and the fourth inclined wall, no matter which direction it drips from the guide wall.

[0017] In some embodiments of this application, a refrigeration device is provided, wherein the sidewall of the waterproof groove is provided with a stepped groove, the stepped groove extends toward the mounting cavity, the bottom of the stepped groove forms a laterally extending bottom wall, the bottom wall is located above the connecting hole; the baffle is located above the bottom wall and abuts against the side of the stepped groove near the waterproof groove.

[0018] Another technical solution described above has the following advantages or beneficial effects: Even if a small amount of water enters the waterproof groove, the baffle plate extends from the end of the connecting wall away from the penetration part towards the groove wall and is located above the installation opening. In this way, the baffle plate can shield the wire harness and wiring terminals installed below. Moreover, the bottom of the stepped groove forms a horizontally extending groove bottom wall located below the baffle plate. The water flow can be blocked by the groove bottom wall, preventing the water flow from directly flowing to the connecting hole, greatly reducing the possibility of water entering the installation cavity, protecting important components such as electrical components in the installation cavity from moisture corrosion, and reducing the risk of electrical faults such as short circuits and leakage.

[0019] In some embodiments of this application, a cooling device is provided, wherein the shielding plate is provided with an upwardly bent and extended sealing rib on the side near the waterproof groove, and the sealing rib is attached to the side wall of the waterproof groove.

[0020] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: In order to further improve the waterproof performance, the shielding plate is provided with an upwardly bent sealing rib on the side near the waterproof groove. The sealing rib is attached to the side wall of the waterproof groove facing the wiring cover, thereby forming a seal between the sealing rib and the side wall of the waterproof groove, which can effectively prevent water from seeping downward from the edge gap between the shielding plate and the side wall of the waterproof groove.

[0021] In some embodiments of this application, a cooling device is provided, wherein a receiving groove is formed on the side of the through portion facing the waterproof groove, the receiving groove is connected to the waterproof groove, and the receiving groove is arranged opposite to the communicating hole; the inner end of the wiring terminal is located in the receiving groove.

[0022] Another technical solution described above has the following advantages or beneficial effects: By placing the inner end of the terminal block within the receiving groove, the side wall of the receiving groove can cover the terminal block. Furthermore, since the receiving groove is located within a waterproof groove, and a baffle plate covers the top of the receiving groove, the possibility of the terminal block being exposed to moisture can be effectively reduced. Moreover, because the wiring harness inside the junction box is arranged within the waterproof groove and connected to the terminal block, and the inner end of the terminal block is placed within the receiving groove, the connection point between the wiring harness and the terminal block can be covered by the receiving groove, further improving the waterproof performance inside the junction box cover, enhancing the stability of the terminal block connection, and ensuring electrical safety.

[0023] In some embodiments of this application, a refrigeration device is provided, wherein the edge of the mounting port is provided with a positioning edge that bends and extends toward one side of the housing, and the positioning edge is arranged circumferentially around the mounting port; the portion of the through-hole extending into the housing through the mounting port is fitted into the inner sidewall of the positioning edge.

[0024] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing a positioning edge at the edge of the installation port, a positioning structure can be provided for the through part to be inserted into the installation port. When the through part is inserted into the box through the installation port, the operator can quickly install the through part at the installation port by installing the through part along the inner side wall of the positioning edge. The through part fitting into the inner side wall of the positioning edge can improve the installation reliability of the wiring cover and can pre-position the wiring cover, thereby improving the installation efficiency.

[0025] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising an adhesive member arranged around the side of the connecting wall near the through portion, the adhesive member being connected to the peripheral edge of the mounting opening to fix the connecting wall to the peripheral edge of the mounting opening.

Furthermore, because the adhesive connects the connecting wall and the periphery of the mounting port to form a sealing structure, it effectively prevents water from entering the refrigeration unit through the gap between the connecting wall and the mounting port.

[0032] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator, or other refrigeration cabinet. The following uses a refrigerator as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0033] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0034] like Figure 1As shown, the refrigeration device provided in this embodiment of the present invention includes a housing 1. The housing 1 can adopt a hollow structure such as a cuboid. The housing 1 forms the outer shell of the refrigeration device. It should be noted that the housing 1 can also adopt a hollow shell structure of other shapes.

[0035] In some embodiments, the housing 1 includes a refrigeration compartment, which can serve as an independent storage space. The refrigeration compartment may have an opening, allowing users to store food within it. Multiple refrigeration compartments may be provided.

[0036] In some embodiments, multiple refrigeration chambers may be provided, which may include freezers, refrigerators, and variable temperature compartments, etc., to meet different refrigeration needs such as freezing, refrigeration, and variable temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigeration chambers may be arranged vertically or horizontally.

[0037] In some embodiments, the refrigeration device may include a liner (not shown in the figure). A refrigeration chamber may be formed inside the liner, and a foamed space may be formed between the liner and the housing 1. By filling the foamed space with foam material, a good heat preservation effect can be achieved for the refrigeration chamber.

[0038] like Figure 1 As shown, in some embodiments, the refrigeration device may include a door 11. The door 11 is movably mounted on the housing 1 and is used to open or close the refrigeration compartment.

[0039] Multiple doors 11 can be provided, and multiple doors 11 can be correspondingly provided on multiple refrigeration compartments. The doors 11 can be movably provided on the cabinet 1 by means of rotation or sliding.

[0040] In some embodiments, the refrigeration system includes a refrigeration system (not shown in the figure). The refrigeration system may be located inside the cabinet 1. The refrigeration system is used to provide cold air to the interior of the refrigerator to maintain a low-temperature environment in each refrigeration compartment.

[0041] In some embodiments, the refrigeration system includes a compressor (not shown). The compressor is the power source for the refrigeration cycle, drawing in low-temperature, low-pressure refrigerant gas and compressing it into a high-temperature, high-pressure gas. The compressor can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0042] In some embodiments, the refrigeration system includes a condenser (not shown). The condenser can be used to receive refrigerant flowing out of the compressor, cooling the high-temperature, high-pressure refrigerant gas from the compressor and converting it into a liquid state. The condenser can transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0043] In some embodiments, the refrigeration system includes a throttling device (not shown). The condenser can deliver the condensed refrigerant to the throttling device. The throttling device may be a capillary tube. The throttling device can be used to reduce the pressure of the refrigerant.

[0044] In some embodiments, the refrigeration system includes an evaporator (not shown). A throttling device can deliver a throttled and depressurized refrigerant into the evaporator.

[0046] Figure 2 for Figure 1 A diagram of the back of the structure.

[0047] like Figure 2 As shown, in some embodiments, the bottom of the housing 1 is provided with a compressor chamber 101, and the compressor and condenser can be installed in the compressor chamber 101.

[0048] Figure 3 for Figure 2 Schematic diagram of the intermediate pressure compressor compartment; Figure 4 for Figure 3 A schematic diagram of an explosion; Figure 5 for Figure 3 A schematic diagram of the junction box structure.

[0049] like Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the refrigeration device includes a junction box 2, which can house wiring harnesses, electrical components, etc. Some of the wiring harnesses in the junction box 2 can be connected to refrigeration components such as compressors and condensers, and some of the wiring harnesses in the junction box 2 can be connected to the electrical control components inside the housing 1, as well as to the compressor, fan, and other structures inside the compressor chamber 101. The side wall of the compressor chamber 101 has a mounting port 102, and the junction box 2 is located at the mounting port 102. Some of the wiring harnesses in the junction box 2 can be connected to the electrical control components inside the housing 1 through the mounting port 102.

[0050] Junction box 2 has a mounting cavity 201 for mounting wire harnesses and electrical components. A waterproof groove 202 is recessed on the outer wall of junction box 2 near the mounting opening 102. The groove wall of the waterproof groove 202 has a connecting hole 203, which connects the waterproof groove 202 to the mounting cavity 201. This allows the wire harness to extend from the mounting cavity 201 to the outside of the waterproof groove 202 for wiring. Furthermore, the waterproof groove 202 on the outer wall of junction box 2 facing the mounting opening 102 acts as a buffer and barrier, preventing moisture in the compressor chamber from flowing directly into the mounting cavity 201 through the gap between the junction box 2 and the mounting opening 102, thus protecting the electrical components inside the junction box 2.

[0051] In some embodiments, the junction box 2 may be provided with a connecting part 20, the connecting part 20 having a connecting hole 206, the connector passing through the connecting hole 206 and connecting to the side wall of the press chamber, thereby fixing the junction box 2 at the mounting port 102.

[0052] Figure 6 for Figure 3 Diagram showing the fit between the junction box and the junction cover; Figure 7 for Figure 6 A cross-sectional schematic diagram.

[0053] like Figure 6 and Figure 7 As shown, in some embodiments, the refrigeration device includes a wiring cover 3 and a wiring terminal 4. The wiring cover 3 is inserted through the mounting opening 102 and located in the waterproof groove 202. The wiring terminal 4 can be disposed on the wiring cover 3. The wiring harness in the mounting cavity 201 can be connected to the electrical control components in the housing 1 through the wiring terminal 4.

[0054] The inner end of the terminal block 4 can be located in the waterproof groove 202 and exposed in the connecting hole 203, so that it can be connected to the wire harness in the junction box 2, and can be connected to the compressor circuit and the internal electrical control circuit of the freezer. The outer end of the terminal block 4 extends out of the outside of the mounting port 102 and is exposed in the wiring cover 3, so that the power supply line or other electrical connection line inside the cabinet 1 can be connected.

[0055] Figure 8 for Figure 4 Schematic diagram of the junction box structure; Figure 9 for Figure 8 A three-dimensional image.

[0056] like Figure 7 , Figure 8 and Figure 9 As shown, the wiring cover 3 includes a through part 31, which is inserted through the mounting opening 102 so that the wiring cover 3 can be fixed on the mounting opening 102.

[0057] The wiring cover 3 includes a connecting wall 32, which is disposed around the edge of the through portion 31 near the waterproof groove 202. The connecting wall 32 can be bent and extended from the side edge of the through portion 31 near the waterproof groove 202 toward the outer periphery of the mounting opening 102, and the connecting wall 32 is attached to the periphery of the mounting opening 102. When the wiring cover 3 is inserted into the mounting opening 102 and installed in place, the connecting wall 32 can be attached to the periphery of the mounting opening 102, thereby forming a circumferential sealing structure around the mounting opening 102, which can effectively prevent water vapor in the compressor chamber from flowing directly into the interior of the mounting opening 102 through the gap between the wiring box 2 and the side wall of the compressor chamber.

[0058] The wiring cover 3 includes a baffle plate 33, which extends from the end of the connecting wall 32 away from the through-hole 31 towards the wall of the waterproof groove 202. The baffle plate 33 can be positioned above the connecting wall 32 and above the mounting opening 102. The end of the baffle plate 33 away from the connecting wall 32 abuts against the wall of the waterproof groove 202, and the baffle plate 33 is positioned above the connecting hole 203. Specifically, one wall of the waterproof groove 202, which is arranged opposite to the side wall of the compressor chamber, abuts against the end of the baffle plate 33 away from the connecting wall 32. Thus, one end of the baffle plate 33 abuts against the peripheral edge above the mounting port 102, and the other end of the baffle plate 33 abuts against the wall of the waterproof groove 202, thereby forming a shield above the connecting hole 203 and above the mounting port 102. Even if some water vapor flows directly into the waterproof groove 202 through the gap between the junction box 2 and the side wall of the compressor chamber, the baffle plate 33 covering the mounting port 102 and the connecting hole 203 can further block most of the water vapor from flowing into the mounting port 102 and the connecting hole, thus achieving an effective waterproof effect.

[0059] In related technologies, the wire hole of the junction box 2 is located on the peripheral wall of the junction box 2. When the freezer is placed outdoors and encounters thunderstorms, moisture can easily enter the interior of the junction box 2 through the wire hole, damaging the junction box 2 and easily causing safety problems.

[0060] In the technical solution of this application, a waterproof groove 202 is recessed on the outer wall of the junction box 2 near the mounting port 102. When the junction box 2 is installed at the mounting port 102, an independent waterproof space is formed between the side wall of the waterproof groove 202 and the side wall of the compressor compartment. When the freezer is placed outdoors and encounters thunderstorms, the waterproof groove 202 can buffer and block water vapor, keeping most of the water vapor outside the junction box 2. Furthermore, the wiring cover 3 is inserted into the mounting port 102 through the through part 31, and the connecting wall 32 is arranged around the periphery of the mounting port 102 and fits against the periphery edge of the mounting port 102, thereby improving the sealing between the wiring cover 3 and the side wall of the mounting port 102 and greatly reducing the risk of water vapor entering the mounting port 102 from the gap between the wiring cover 3 and the side wall of the compressor compartment. Furthermore, the shield 33 extends from the end of the connecting wall 32 away from the through part 31 towards the wall of the waterproof groove 202 and is located above the mounting opening 102. In this way, the shield 33 can shield the wire harness and terminal 4 installed below. Even if a small amount of water vapor enters the waterproof groove 202, the rainwater will be blocked by the shield 33 and will not drip directly onto the mounting opening 102 and the connecting hole 203. This prevents rainwater from entering the junction box 2 through these parts and flowing to the wire harness and terminal 4, thus avoiding safety problems such as short circuits and leakage caused by water vapor intrusion into the terminal 4. This improves the safety and reliability of the junction box 2 in the compressor chamber 101.

[0061] Figure 10 for Figure 9 A schematic diagram from another perspective.

[0062] like Figure 6 and Figure 10 As shown, in some embodiments, the top of the shield 33 may be provided with a first inclined wall 331, which extends downward at an angle toward the outside of the mounting opening 102. By providing the first inclined wall 331 at the top of the shield 33, rainwater flows downward at an angle along the surface of the shield 33 and then deviates from the mounting opening 102 and the connecting hole 203, thus preventing rainwater from accumulating above the mounting opening 102 and the connecting hole.

[0063] In some embodiments, the top of the baffle 33 may be provided with a second inclined wall 332, which extends downward at an angle toward the outer side of the mounting opening 102. By providing the second inclined wall 332 at the top of the baffle 33, rainwater flows downward at an angle along the surface of the baffle 33 and then deviates from the mounting opening 102 and the connecting hole 203, thus preventing rainwater from accumulating above the mounting opening 102 and the connecting hole.

[0064] like Figure 8 , Figure 9 and Figure 10As shown, in some embodiments, the top of the baffle 33 may be provided with a first inclined wall 331 and a second inclined wall 332. One end of the first inclined wall 331 is connected to one end of the second inclined wall 332, and the other end of the first inclined wall 331 extends downward at an angle away from the second inclined wall 332, extending to one side of the mounting opening 102. The other end of the second inclined wall 332 extends downward at an angle away from the first inclined wall 331, extending to the other side of the mounting opening 102. Specifically, the other end of the first inclined wall 331 extends to one outer side of the mounting opening 102, and the other end of the second inclined wall 332 extends to the other outer side of the mounting opening 102.

[0065] Specifically, by providing a first inclined wall 331 and a second inclined wall 332 on the top of the shielding plate 33, with the first inclined wall 331 extending downward at an angle away from the second inclined wall 332, and the second inclined wall 332 extending downward at an angle away from the first inclined wall 331, the connection end of the first inclined wall 331 and the second inclined wall 332 can form the highest point of the shielding plate 33, and both ends are inclined downward towards the sides of the mounting opening 102 respectively. The top of the shielding plate 33 forms a roof-like structure, so that water vapor can flow naturally along the slope of the inclined wall no matter which direction it drips from, thus improving the hydrophobicity of the top of the shielding plate 33.

[0066] Specifically, as water vapor drips downwards through the baffle 33, the first inclined wall 331 and the second inclined wall 332 effectively guide the water vapor downwards and away from the installation opening 102, preventing rainwater from accumulating on the top of the baffle 33 and thus increasing the chance of rainwater entering the distribution space of the wiring harness and terminals 4 through the gap between the baffle 33 and the wall of the waterproof groove 202. This allows the electrical components, wiring harness, and terminals 4 within the waterproof groove 202 to operate in a dry environment, reducing performance degradation and safety issues caused by moisture.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments, the waterproof groove 202 may have a first groove sidewall 2021 and a second groove sidewall 2022 arranged opposite to each other. The first groove sidewall 2021 is spaced apart from the left side of the wiring cover 3 and may form a first gap 2041. The first gap 2041 extends along the height direction of the waterproof groove 202, and the upper end of the first gap 2041 extends upward to the end of the first inclined wall 331 away from the second inclined wall 332.

[0068] The upper end of the first gap 2041 can extend to the end of the first inclined wall 331 away from the second inclined wall 332. Water vapor flowing downward along the first inclined wall 331 can directly enter the first gap 2041, and the water vapor entering the first gap 2041 can continue to flow downward along its height extension direction, thereby preventing water vapor from accumulating at the top edge of the wiring cover 3.

[0069] like Figure 6 As shown, in some embodiments, the second groove sidewall 2022 is spaced apart from the right side of the wiring cover 3 and can form a second gap 2042. The second gap 2042 extends along the height direction of the waterproof groove 202, and the upper end of the second gap 2042 extends upward to the end of the second inclined wall 332 away from the first inclined wall 331.

[0070] The upper end of the second gap 2042 can extend to the end of the second inclined wall 332 away from the first inclined wall 331. Water vapor flowing downward along the second inclined wall 332 can directly enter the second gap 2042, and the water vapor entering the second gap 2042 can continue to flow downward along its height extension direction, thereby preventing water vapor from accumulating at the top edge of the wiring cover 3.

[0071] In some embodiments, a guide wall 21 can be formed on the top wall of the junction box 2. The guide wall 21 is located above the waterproof groove 202, thereby blocking the water vapor in the compressor chamber and effectively keeping most of the water vapor outside the waterproof groove 202. Moreover, the guide wall 21 can be set at a certain angle to tilt downwards, thereby guiding the water vapor on the top of the junction box 2 and preventing water vapor from accumulating on the top of the junction box 2.

[0072] like Figure 5 and Figure 6 As shown, the junction box 2 has a first outer side wall 22 and a second outer side wall 23 disposed opposite to each other. The first outer side wall 22 may be disposed on the outside of the first groove side wall 2021 of the waterproof groove 202, and the second outer side wall 23 may be disposed on the outside of the second groove side wall 2022 of the waterproof groove 202. The flow guide wall 21 is arranged to extend downward at an angle toward the side facing the first outer side wall 22 or the flow guide wall 21 is arranged to extend downward at an angle toward the side facing the second outer side wall 23.

[0073] By arranging the guide wall 21 to extend downward at an angle toward either the first outer wall 22 or the second outer wall 23, rainwater can flow downward at an angle along the surface of the guide wall 21 and toward the outside of the junction box 2. This allows water vapor to flow away from the waterproof groove 202, preventing the risk of leakage from the top wall of the junction box 2 into the waterproof groove 202 due to excessive water accumulation. This helps to keep the electrical components inside the junction box 2 and the wiring terminals 4 located in the waterproof groove 202 in a dry working environment.

[0074] like Figure 5 As shown, in some embodiments, the flow guide wall 21 may include a third inclined wall 211 and a fourth inclined wall 212. One end of the third inclined wall 211 is connected to one end of the fourth inclined wall 212. The other end of the third inclined wall 211 may extend downward at an angle away from the fourth inclined wall 212 and extend to one side of the first outer wall 22. The other end of the fourth inclined wall 212 may extend downward at an angle away from the third inclined wall 211 and extend to one side of the second outer wall 23.

[0075] Specifically, by providing a third inclined wall 211 and a fourth inclined wall 212 on the guide wall 21, with the third inclined wall 211 and the fourth inclined wall 212 located at the top of the waterproof groove 202, the third inclined wall 211 extends downward at an angle away from the fourth inclined wall 212, and the fourth inclined wall 212 extends downward at an angle away from the third inclined wall 211, the connection end of the third inclined wall 211 and the fourth inclined wall 212 can form the highest point of the guide wall 21, and both ends are inclined downward towards the sides of the junction box 2, and the top of the junction box 2 can form a roof-like structure, so that water vapor can flow naturally along the slope of the third inclined wall 211 and the fourth inclined wall 212, no matter which direction it drips from the guide wall 21.

[0076] Specifically, after the water vapor flows to the top of the junction box 2, the third inclined wall 211 and the fourth inclined wall 212 can effectively guide the water vapor to flow downward and to the outer periphery of the junction box 2, so as to avoid rainwater accumulating on the top of the junction box 2 and thus increasing the risk of rainwater entering the interior of the waterproof groove 202 through the gap between the guide wall 21 and the side wall of the compressor chamber.

[0077] Figure 11 for Figure 6 An exploded image.

[0078] like Figure 5 and Figure 6As shown, in some embodiments, the sidewall of the waterproof groove 202 may be provided with a stepped groove 205, which extends toward the mounting cavity 201. The bottom of the stepped groove 205 forms a laterally extending bottom wall 24, which is located above the connecting hole. A baffle plate 33 is located above the bottom wall 24, and the baffle plate 33 abuts against the side of the stepped groove 205 near the waterproof groove 202.

[0079] The stepped groove 205 formed by the side wall of the waterproof groove 202 extends toward the mounting cavity 201. The baffle 33 is located above the bottom wall 24 of the groove and can extend toward one side of the stepped groove 205 and abut against the side of the stepped groove 205 located inside the waterproof groove 202, thereby forming a multi-layer waterproof structure for the wire harness and the terminal 4 inside the waterproof groove 202.

[0080] Specifically, when the water flow in the compressor chamber flows towards the surface of the junction box 2, it is first blocked by the guide wall 21, thus blocking most of the water flow. Even if a small amount of water flows into the waterproof groove 202, the baffle plate 33 extends from the end of the connecting wall 32 away from the through part 31 towards the groove wall of the waterproof groove 202 and is located above the mounting port 102. In this way, the baffle plate 33 can block the wire harness and wiring terminal 4 installed below. Furthermore, the bottom of the stepped groove 205 forms a horizontally extending groove bottom wall 24 located below the baffle plate 33. The water flow can be blocked by the groove bottom wall 24, preventing the water flow from flowing directly to the connecting hole, greatly reducing the possibility of water flowing into the mounting cavity 201, protecting the electrical components and other important parts in the mounting cavity 201 from moisture corrosion, and reducing the risk of electrical faults such as short circuits and leakage.

[0081] The combination of the baffle plate 33 and the stepped groove 205 further blocks the path of water flow into the installation cavity 201. Even if water flows into the waterproof groove 202, the water vapor must bypass the baffle plate 33 and the bottom wall 24 of the groove before entering the installation cavity 201. The structural cooperation between the junction box 2 and the junction cover 3 can effectively improve the overall waterproofness and protect the wire harness and terminal 4 inside the junction box 2 and the junction cover 3.

[0082] Figure 12 for Figure 7 A schematic diagram from another perspective.

[0083] like Figure 10 and Figure 12 As shown, in some embodiments, the side of the baffle plate 33 near the waterproof groove 202 may be provided with an upwardly bent sealing rib 34, which is attached to the side wall of the waterproof groove 202. The sealing rib 34 may extend along the connection point where the baffle plate 33 abuts against the side wall of the waterproof groove 202.

[0084] Specifically, in order to further improve the waterproof performance, the shielding plate 33 is provided with an upwardly bent sealing rib 34 on the side near the waterproof groove 202. The sealing rib 34 is attached to the side wall of the waterproof groove 202 facing the wiring cover 3, thereby forming a seal between the sealing rib 34 and the side wall of the waterproof groove 202, which can effectively prevent water from seeping downward from the edge gap between the shielding plate 33 and the side wall of the waterproof groove 202.

[0085] like Figure 7 , Figure 9 and Figure 10 As shown, in some embodiments, the side of the through-hole 31 facing the waterproof groove 202 can correspondingly form a receiving groove 301. Specifically, the through-hole 31 has a protruding structure facing the outside of the mounting opening 102, and the protruding structure of the through-hole 31 is recessed inside the press chamber to form a receiving groove 301. The receiving groove 301 communicates with the waterproof groove 202, and the receiving groove 301 is arranged opposite to the connecting hole 203, so that the wire harness in the junction box 2 can extend into the waterproof groove 202 through the connecting hole 203 and be connected to the terminal 4 through the receiving groove 301. The inner end of the terminal 4 is located in the receiving groove 301.

[0086] Specifically, by placing the inner end of the terminal block 4 within the receiving groove 301, the sidewall of the receiving groove 301 can cover the terminal block 4. Furthermore, the receiving groove 301 is located within the waterproof groove 202, and the baffle plate 33 covers the top of the receiving groove 301, effectively reducing the possibility of the terminal block 4 becoming wet due to exposure to moisture. Moreover, since the wiring harness inside the junction box 2 is arranged within the waterproof groove 202 and connected to the terminal block 4, and the inner end of the terminal block 4 is placed within the receiving groove 301, the connection point between the wiring harness and the terminal block 4 can be covered by the receiving groove 301, further improving the waterproof performance inside the junction box 3, enhancing the stability of the terminal block 4 connection, and ensuring electrical safety.

[0087] Figure 13 for Figure 3 A schematic diagram from another perspective.

[0088] like Figure 13 As shown, in some embodiments, the edge of the mounting opening 102 may be provided with a positioning edge 12 that bends and extends toward one side of the housing 1. The positioning edge 12 is located on the outside of the press chamber and may be in a ring shape, circumferentially surrounding the mounting opening 102. The portion of the through-hole 31 that extends into the housing 1 through the mounting opening 102 is fitted onto the inner wall of the positioning edge 12.

[0089] Specifically, by providing a positioning edge 12 at the edge of the mounting opening 102, a positioning structure is provided for the through-hole part 31 to pass through the mounting opening 102. When the through-hole part 31 is inserted into the housing 1 through the mounting opening 102, the operator can quickly install the through-hole part 31 at the mounting opening 102 by installing it along the inner sidewall of the positioning edge 12. The positioning edge 12 can constrain the boss from multiple directions to prevent the through-hole part 31 from shifting or shaking during installation. Moreover, the through-hole part 31 fitting into the inner sidewall of the positioning edge 12 can improve the installation reliability of the wiring cover 3 and can pre-position the wiring cover 3, thereby improving installation efficiency.

[0090] like Figure 12 As shown, in some embodiments, the refrigeration device may include an adhesive 5, which may be in the form of a ring. The adhesive 5 is arranged around the side of the connecting wall 32 near the through portion 31. The adhesive 5 is connected to the peripheral edge of the mounting port 102 to fix the connecting wall 32 to the peripheral edge of the mounting port 102.

[0091] Specifically, the adhesive 5 is arranged around the side of the connecting wall 32 near the through-hole 31 and connected to the peripheral edge of the mounting port 102, so that the connecting wall 32 can be fixed at the mounting port 102. In this way, the tight connection between the adhesive 5 and the peripheral edge of the mounting port 102 prevents the connecting wall 32 from loosening or shifting during use, thereby improving the connection reliability between the wiring cover 3 and the side wall of the compressor chamber.

[0092] On the other hand, since the adhesive 5 is connected to the periphery of the connecting wall 32 and the mounting port 102 to form a sealing structure, even if water vapor outside the junction box 2 enters the waterproof groove 202, it can effectively prevent water from entering the interior of the refrigeration device from the gap between the connecting wall 32 and the mounting port 102.

[0093] In some embodiments, the adhesive 5 arranged near the top of the junction box 2 may extend beyond the top of the baffle 33. Even if moisture from outside the junction box 2 enters the waterproof groove 202, the water on the top of the adhesive 5 can flow downwards to the top of the baffle 33, and then flow away from the mounting opening 102 through the first inclined wall 331 or the second inclined wall 332.

[0094] In some other embodiments, the outer side of the mounting port 102 is a foam layer (not shown in the figure). After the part of the through-hole 31 extends into the inside of the housing 1 through the mounting port 102 and is pre-positioned by fitting into the inner side wall of the positioning edge 12, the foam material in the foam layer can be connected with the part of the through-hole 31 that protrudes from the mounting port 102. After the foam material is cured, the wiring cover 3 can be fixed on the side wall of the press chamber.

[0095] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of this application is limited only by the appended claims.
