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] Currently, the top of the refrigeration compartment of the freezer is equipped with a refrigeration duct. The refrigeration duct contains an evaporator and a fan. When the fan is turned on, the airflow formed in the refrigeration duct flows through the evaporator to form cold air, which is then delivered to the refrigeration compartment to create a low-temperature environment.

[0004] Generally, a drain pipe is also installed on the refrigeration duct to transport condensate from the surface of the refrigeration duct or evaporator to a drip tray. In double-door freezers, the drain pipe is often obstructed because it is located behind the upright mounting plate or other decorative panels. This makes it difficult to remove and install the drain pipe when the refrigeration duct needs to be disassembled for maintenance or replacement of the evaporator or fan inside, thus increasing the difficulty of future maintenance of the freezer. Summary of the Invention

[0005] Based on existing technology, a refrigeration device is provided to improve the problem of disassembly, assembly, and maintenance of components inside the refrigeration duct of a freezer due to the installation structure of the drain pipe and the refrigeration duct.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: One aspect of this application provides a refrigeration device, including a housing forming the outer shell of the refrigeration device; a refrigeration chamber is provided inside the housing; a refrigeration duct is provided at the top of the refrigeration chamber, and a drain outlet is provided at the rear end of the refrigeration duct; a guide member is provided on the rear wall of the refrigeration chamber, and the guide member is located below the drain outlet; the top of the guide member has an opening, and the opening is correspondingly located below the drain outlet; the bottom of the guide member has a drain hole; and a drain pipe is located below the guide member and connected to the drain hole; wherein the guide member is used to receive condensate at the drain outlet, and the condensate can drip into the guide member through the opening and flow downward into the drain pipe through the drain hole.

[0007] The above technical solution has the following advantages or beneficial effects: The top of the guide component is open, which allows the guide component to be separated from the refrigeration duct while also allowing it to collect condensate from the drain outlet and guide it to the drain pipe below. When it is necessary to disassemble the refrigeration duct for maintenance of the fan, evaporator, or other structures within the refrigeration duct, operators do not need to remove the column mounting plate or cover on the front side of the drain pipe, or disassemble and reconnect the drain pipe to the refrigeration duct. This allows maintenance personnel to directly disassemble the refrigeration duct, simplifying the disassembly and maintenance process, reducing the difficulty of disassembling and assembling the drain pipe, and improving subsequent maintenance efficiency.

[0008] In some embodiments of this application, a refrigeration device is provided, wherein the guide members are arranged at intervals below the drain port.

[0009] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: By arranging the guide components and the drain outlet at intervals, there is a gap between the guide components and the drain outlet of the refrigeration air duct. When it is necessary to disassemble the refrigeration air duct to repair or replace the internal evaporator or fan, it is not only unnecessary to disassemble the refrigeration air duct and the guide components, but it also facilitates the disassembly process of the refrigeration air duct, so as to avoid mutual interference between the refrigeration air duct and the guide components. In this way, the spaced guide components will not hinder the operation of maintenance personnel. The operators do not need to remove a large number of components that may block the drain pipe first, thereby reducing the difficulty of disassembling and assembling the refrigeration air duct and improving maintenance efficiency.

[0010] In some embodiments of this application, a refrigeration device is provided, wherein a drain nozzle is provided at the rear end of the refrigeration duct, the drain nozzle extends downward from the bottom of the refrigeration duct, and the lower end of the drain nozzle forms the drain port; an opening is arranged at intervals below the drain nozzle, and the drain nozzle is arranged close to the center of the opening.

[0011] Another technical solution described above has the following advantages or beneficial effects: When the fan operates within the refrigeration duct, airflow is generated, which can easily affect the drainage process at the drain outlet at the rear end of the refrigeration duct. By providing a guide nozzle at the rear end of the refrigeration duct, extending downwards from the bottom of the refrigeration duct to serve as a guiding channel for the condensate, the condensate entering the guide nozzle can flow more concentratedly towards the guide element. This allows for more concentrated and precise guidance of the condensate at the drain outlet into the guide element. In this way, with the condensate guided by the guide nozzle, splashing during the drainage process is avoided.

[0012] In some embodiments of this application, a refrigeration device is provided, wherein the sidewall of the opening includes a first sidewall attached to the rear wall of the refrigeration chamber; a second sidewall, the rear end of which is connected to one side of the first sidewall; a third sidewall disposed opposite to the front side of the first sidewall, one side of which is connected to the second sidewall; and a fourth sidewall, the front end of which is connected to the side of the third sidewall away from the second sidewall, and the rear end of which is connected to the side of the first sidewall away from the second sidewall; the top ends of the first sidewall, the second sidewall, the third sidewall, and the fourth sidewall form the opening; in the direction from bottom to top of the housing, the top end of at least one of the second sidewall, the third sidewall, and the fourth sidewall extends obliquely toward the outer periphery of the opening.

[0013] Another technical solution described above has the following advantages or beneficial effects: the tops of the first, second, third, and fourth sidewalls form an opening, creating a receiving area with a certain volume. Specifically, the top of at least one of the second, third, and fourth sidewalls extends obliquely towards the outer periphery of the opening, thus creating a structure where the opening area gradually increases from bottom to top along the box body. Simultaneously, because the top of at least one of the second, third, and fourth sidewalls extends obliquely towards the outer periphery of the opening, the interior of the guide member forms an oblique structure. When condensate flows to the upper end of the oblique second, third, and fourth sidewalls, it can flow more smoothly into the interior of the opening along the oblique surface, thereby improving the condensate receiving efficiency.

[0014] In some embodiments of this application, a refrigeration device is provided, wherein the flow guide further includes a fixed wall, the fixed wall extending upward from the side wall of the opening, the fixed wall having a fixing hole, the fixing hole being elongated, the length direction of the fixing hole extending along the height direction of the housing; the fixed wall is fixedly connected to the rear wall of the refrigeration chamber through the fixing hole.

[0015] Another technical solution described above has the following advantages or beneficial effects: A fixing hole can be provided on the fixed wall, and a connector can pass through the fixing hole, with the other end of the connector passing through the rear wall of the refrigeration compartment, thereby fixing the guide component inside the refrigeration compartment. The elongated fixing hole on the fixed wall provides adjustment space for installation. When bolts or other connectors are used to connect to the rear wall of the refrigeration compartment through the fixing hole, because the fixing hole is elongated and its length extends along the height direction of the enclosure, the connector can move up and down within the length range of the fixing hole, thereby achieving position adjustment of the guide component in the height direction.

[0016] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further comprising a cover plate disposed on the rear wall of the refrigeration chamber and located below the refrigeration air duct, the cover plate and the rear wall of the refrigeration chamber forming an installation cavity; the cover plate extends along the height direction of the housing; the drain pipe is installed in the installation cavity.

[0017] Another technical solution described above has the following advantages or beneficial effects: the rear end of the shelf is fixed to the cover plate, and the connection between the cover plate and the rear wall of the refrigeration chamber provides structural support for the shelf, thereby effectively dispersing the weight of the shelf and the items on it, reducing the deformation and swaying of the shelf. By setting the cover plate, not only can the drain pipe be covered to ensure the aesthetics of the refrigeration chamber, but the shelf can also be supported, improving the stability of the shelf in use.

[0018] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further includes multiple shelves, the multiple shelves are arranged at intervals along the height direction of the box; the rear end of the shelf is fixed to the cover plate.

[0019] Another technical solution described above has the following advantages or beneficial effects: the two sides of the shelf can be supported on two opposite side walls inside the refrigeration room. The rear end of the shelf is fixed to a cover plate, and the connection between the cover plate and the rear wall of the refrigeration room provides structural support for the shelf, thereby effectively distributing the weight of the shelf and the items on it, reducing deformation and swaying. By setting the cover plate, not only can the drain pipe be concealed to ensure the aesthetics of the refrigeration room, but the shelf can also be supported, improving its stability.

[0020] In some embodiments of this application, a refrigeration device is provided, wherein the shelf includes a left support portion and a right support portion, the left support portion and the right support portion being arranged adjacent to each other on the left and right sides; the side of the left support portion near the right support portion is fixed to the left side of the front wall of the cover plate; the side of the right support portion near the left support portion is fixed to the right side of the front wall of the cover plate.

[0021] Another technical solution mentioned above has the following advantages or beneficial effects: In some large-capacity freezer structures, the lateral dimensions of the freezer are relatively large. By setting left and right support sections, the two sides of the front wall of the cover can respectively support the left and right support sections. Compared with a structure where the shelf is fixed at a single point in the middle, this can increase the support force on the shelf, improve the effect of the shelf evenly bearing the weight of the items, and avoid the shelf bending or breaking due to excessive local stress. The cover not only can shield the drain pipe, but also provide support for the left and right support sections respectively.

[0022] In some embodiments of this application, a refrigeration device is provided, the refrigeration device further including a support hook, the support hook being disposed on the front wall of the cover plate; multiple support hooks are provided, the multiple support hooks being spaced apart along the height direction of the cover plate; the rear end of the shelf is provided with a slot, the slot being correspondingly disposed with the support hook, and the shelf being hooked onto the support hook through the slot.

[0023] Another technical solution described above has the following advantages or beneficial effects: the rear end of the shelf has a slot corresponding to the support hook, allowing the shelf to be detachably connected to the support hook on the cover plate. Users simply align the slot at the rear end of the shelf with the support hook on the cover plate and gently press or push the shelf downwards to complete the installation. Similarly, disassembly is as simple as lifting the shelf upwards to detach it from the support hook. This enables quick installation and disassembly of the shelf, improving the user experience. Furthermore, the corresponding engagement of the slot and support hook on the shelf provides additional support, preventing it from shaking or falling off.

[0024] In some embodiments of this application, a refrigeration device is provided, the refrigeration device including a first door and a second door, the first door and the second door being arranged adjacent to each other on the left and right, the first door and the second door covering the opening of the refrigeration compartment; the cover plate is correspondingly provided on the rear side of the first door and the second door being arranged adjacent to each other.

[0025] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: the cover plate is arranged adjacent to the rear side of the first and second cabinet doors, and the mounting cavity formed between the cover plate and the rear wall of the refrigeration chamber is located adjacent to the rear side of the first and second cabinet doors. That is, the drain pipe can be arranged adjacent to the rear side of the first and second cabinet doors. Furthermore, a drain port is provided at the middle position of the rear end of the refrigeration duct corresponding to the two cabinet doors. The condensate in the refrigeration duct can be collected at the middle position and then dripped into the guide component through the drain port, and flow to the drain pipe through the guide component. This can improve the efficiency of condensate discharge from the refrigeration duct and avoid the drain pipe of the refrigeration duct being arranged on one side of the refrigeration duct and the drain pipe being arranged on one side of the refrigeration chamber, which would increase the time for condensate to be discharged from the refrigeration duct.

[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 1 As 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] like Figure 1 As shown, in some embodiments, the housing 1 includes a refrigeration compartment 101, which can serve as an independent storage space. The refrigeration compartment 101 may have an opening, allowing users to store food within it. Multiple refrigeration compartments 101 may be provided.

[0036] In some embodiments, multiple refrigeration chambers 101 may be provided, which may be freezers, refrigerators, and variable temperature chambers, 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 101 may be arranged vertically or horizontally.

[0037] In some embodiments, the refrigeration device may include a cabinet liner (not shown in the figure). The refrigeration chamber 101 may be formed inside the cabinet liner, and a foamed space may be formed between the cabinet liner and the cabinet body 1. By filling the foamed space with foam material, the refrigeration chamber 101 can achieve a good heat preservation effect.

[0038] In some embodiments, the refrigeration unit may include a door. The door is movably mounted on the housing 1 and is used to open or close the refrigeration compartment 101.

[0039] Multiple doors can be installed, and multiple doors can be installed on multiple refrigeration compartments 101. The doors can be installed 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 inside of the refrigerator to maintain a low-temperature environment in each refrigeration compartment 101.

[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] Figure 2 for Figure 1 A partial view of the back. (The image shows the back side.) Figure 2 A schematic diagram showing the rear wall of the refrigeration unit being concealed.

[0045] like Figure 2 As shown, in some embodiments, the refrigeration system includes an evaporator 11. A throttling device can deliver a throttled and depressurized refrigerant into the evaporator 11. The evaporator 11 can be used for refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0046] In some embodiments, the compressor, condenser, throttling device, and evaporator 11 can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration of the interior of the housing 1.

[0047] like Figure 2 As shown, in some embodiments, the refrigeration device includes a refrigeration duct 200, a fan 12 may be installed in the refrigeration duct 200, and an evaporator 11 is installed in the refrigeration duct 200. When the fan 12 is started, air in the refrigeration chamber 101 can enter the refrigeration duct 200, and after passing through the evaporator 11, form cold air, which then flows into the refrigeration chamber 101 to cool the items in the refrigeration chamber 101.

[0048] Figure 3 for Figure 1 A three-dimensional schematic diagram.

[0049] like Figure 2 and Figure 3 As shown, the refrigeration duct 200 is located at the top of the refrigeration chamber 101, and a drain port 201 is provided at the rear end of the refrigeration duct 200. During the refrigeration process of the refrigeration device, condensate may form on the surface of the evaporator 11. By providing a drain port 201 at the rear end of the refrigeration duct 200, the condensate can leave the refrigeration duct 200 through the drain port 201, avoiding accumulation inside the refrigeration duct 200.

[0050] Figure 4 for Figure 3 A three-dimensional schematic diagram of the stroke duct shell.

[0051] like Figure 4 As shown, in some embodiments, the refrigeration chamber 101 may include a duct shell 2, which forms a refrigeration duct 200 by enclosing the duct shell 2 and the side wall of the refrigeration chamber 101; the bottom wall of the duct shell 2 extends downward at an angle along the front to back direction of the housing 1, and a drain port 201 is provided at the rear end of the bottom wall of the duct shell 2.

[0052] In this configuration, by extending the bottom wall of the duct housing 2 at an angle downwards, the condensate formed inside the duct housing 2 can automatically flow towards the drain port 201 via the downward angle of the bottom wall. Specifically, the rear end of the duct housing 2 protrudes to form a drain section 22, which is located above the guide member 3. The bottom wall of the drain section 22 extends downwards at an angle, and the drain port 201 is located on the bottom wall of the drain section 22. A guide nozzle 21 is located at the bottom of the drain section 22.

[0053] Figure 5 for Figure 2 A partial schematic diagram of point A in the diagram; Figure 6 for Figure 3 A schematic diagram of the layout of the cooling air duct and air guide components.

[0054] like Figure 5 and Figure 6As shown, in some embodiments, the refrigeration device includes a flow guide 3, which is disposed on the rear wall of the refrigeration chamber 101 and below the drain port 201. The top of the flow guide 3 has an opening 301, correspondingly located below the drain port 201, to collect condensate dripping from the drain port 201. The bottom of the flow guide 3 has a liquid outlet 302, allowing condensate to be discharged outside the flow guide 3 after entering it.

[0055] In some embodiments, the refrigeration device includes a drain pipe 4, which is located below the guide member 3 and connected to the liquid outlet 302. The drain pipe 4 can extend along the height direction of the refrigeration chamber 101, with its upper end connected to the bottom of the guide member 3 and its lower end extending into the water receiving tray inside the compressor chamber 102.

[0056] The guide member 3 is used to receive the condensate at the drain outlet 201. The condensate can drip into the guide member 3 through the opening 301 and flow downward into the drain pipe 4 through the outlet hole 302.

[0057] Specifically, by placing the guide member 3 below the drain port 201 of the refrigeration duct 200, and providing an opening 301 at the top of the guide member 3 to collect the condensate at the drain port 201, the condensate is guided to the drain pipe 4 below. In this way, the drain pipe 4 is connected to the drain hole 302 of the refrigeration duct 200 at intervals through the guide member 3, and the guide member 3 is separately disposed from the refrigeration duct 200, so that the refrigeration duct 200 and the guide member 3 are in a non-connected state, and the refrigeration duct 200, the guide member 3, and the drain pipe 4 are relatively independent. When it is necessary to disassemble the refrigeration duct 200 and then disassemble and repair the fan 12, evaporator 11 or other structures inside the refrigeration duct 200, the refrigeration duct 200 can be removed directly for repair work. After repair, the refrigeration duct 200 can be installed on the top of the refrigeration chamber 101. The drain port 201 can be correspondingly located on the top of the opening 301 of the guide 3, so as not to affect the condensate drainage process inside the refrigeration duct 200.

[0058] like Figure 2 As shown, in some embodiments, the refrigeration device may include a cover plate 5, which is disposed on the rear wall of the refrigeration chamber 101 and located below the refrigeration air duct 200. An installation cavity 501 is formed between the cover plate 5 and the rear wall of the refrigeration chamber 101. The cover plate 5 may extend along the height direction of the housing 1. A drain pipe 4 is installed within the installation cavity 501.

[0059] The cover plate 5 can be used as a decorative plate for the drain pipe. By setting the cover plate 5 on the rear wall of the refrigeration chamber 101, the mounting cavity 501 formed between the cover plate 5 and the rear wall of the refrigeration chamber 101 can be used to install the drain pipe, thereby covering the drain pipe 4 and preventing the drain pipe 4 from being directly exposed in the refrigeration chamber 101.

[0060] Specifically, the mounting cavity 501 formed between the cover plate 5 and the rear wall of the refrigeration chamber 101 extends along the height direction of the box body 1, thereby adapting to the size and direction of the drain pipe 4, so that the drain pipe 4 can be laid in the mounting cavity 501 according to a predetermined path, avoiding interference with other components.

[0061] In current related technologies, the drain pipe 4 is covered by a cover plate 5 on its front side, or by placing the drain pipe 4 on the back of the column mounting plate, thus obscuring the drain pipe 4 and satisfying the aesthetic requirements of the interior of the refrigeration room 101. When it is necessary to disassemble the refrigeration duct 200 to repair or replace the evaporator 11 or fan 12 inside, the column mounting plate or cover plate 5 on the front side of the drain pipe 4 needs to be removed in order to disconnect the drain pipe 4 from the refrigeration duct 200 and remove the refrigeration duct 200 from the refrigeration duct 200. Furthermore, after the refrigeration duct 200 is reinstalled in the refrigeration room 101, the column mounting plate or cover plate 5 needs to be re-fixed to the front side of the drain pipe 4.

[0062] In the technical solution of this application, a guide member 3 is provided below the drain port 201 of the refrigeration duct 200. The top of the guide member 3 has an opening 301. By providing the opening 301, the guide member 3 can be separated from the refrigeration duct 200, while also allowing the guide member 3 to collect the condensate at the drain port 201 and guide the condensate to the drain pipe 4 below. When it is necessary to disassemble the refrigeration duct 200 to disassemble and repair the fan 12, evaporator 11, or other structures within the refrigeration duct 200, the operator does not need to disassemble the column mounting plate or cover plate 5 on the front side of the drain pipe 4, or disassemble and reconnect the drain pipe 4 to the refrigeration duct 200. In this way, maintenance personnel can directly disassemble the refrigeration duct 200, simplifying the disassembly, assembly, and repair process and improving the efficiency of subsequent maintenance.

[0063] like Figure 5 and Figure 6As shown, in some embodiments, the guide members 3 are spaced apart below the drain port 201. By arranging the guide members 3 and the drain port 201 vertically at intervals, there is a gap between the guide members 3 and the drain port 201 of the refrigeration duct 200. When the refrigeration duct 200 needs to be disassembled for maintenance or replacement of the internal evaporator 11 or fan 12, it is not necessary to disassemble the refrigeration duct 200 and the guide members 3. Moreover, it facilitates the disassembly process of the refrigeration duct 200, preventing mutual interference between the refrigeration duct 200 and the guide members 3. In this way, the spaced-apart guide members 3 will not hinder the operation of maintenance personnel. The operator does not need to remove a large number of components that may block the drain pipe 4 first, thereby reducing the difficulty of disassembling and assembling the drain pipe 4 and improving maintenance efficiency.

[0064] In some other embodiments, the air guide 3 can be detachably connected to the cooling duct 200, such as by magnetic attraction, snap-fit, or other detachable structures, to facilitate the assembly and disassembly of the air guide 3 and the cooling duct 200.

[0065] like Figure 4 and Figure 5 As shown, in some embodiments, the rear end of the cooling duct 200 may be provided with a drain nozzle 21, which may be arranged at intervals above the opening 301 of the guide member 3. The drain nozzle 21 may extend downward from the bottom of the cooling duct 200, and the drain nozzle 21 may be columnar, with the lower end of the drain nozzle 21 forming a drain port 201.

[0066] When the fan 12 runs within the refrigeration duct 200, airflow is generated, which can easily affect the drainage process at the drain port 201 at the rear end of the refrigeration duct 200. By providing a guide nozzle 21 at the rear end of the refrigeration duct 200, extending downwards from the bottom to serve as a guide channel for condensate, the condensate entering the guide nozzle 21 can flow more concentratedly towards the guide member 3. This allows for more concentrated and precise guidance of the condensate at the drain port 201 into the guide member 3. In this way, with the condensate guided by the guide nozzle 21, splashing during the drainage process is avoided.

[0067] Furthermore, the openings 301 can be spaced apart below the drain nozzles 21, and the drain nozzles 21 can be arranged close to the center of the openings 301. When the condensate flows out from the drain port 201 at the lower end of the drain nozzles 21, due to the guiding effect of the drain nozzles 21, the condensate can enter the guide member 3 through the center of the openings 301 to a greater extent. In this way, the guide member 3 can receive the dripping condensate to a greater extent, so that the condensate enters the guide member 3 more accurately and reduces the possibility of condensate splashing out of the outside of the guide member 3.

[0068] Figure 7for Figure 6 A three-dimensional schematic diagram of the central guide component; Figure 8 for Figure 7 A three-dimensional diagram from another perspective.

[0069] like Figure 7 and Figure 8 As shown, in some embodiments, the opening area of ​​the opening 301 gradually increases along the direction from bottom to top along the box 1.

[0070] Because condensate tends to diffuse as it drips from drain 201 into guide member 3, it may scatter as it flows out of drain 201 and fall into guide member 3. By making the opening of opening 301 gradually increase in area from bottom to top, the diffusion range of the falling condensate can be better matched, allowing the condensate to fall more smoothly into opening 301 during natural descent. This improves the receiving efficiency of guide member 3 and reduces the possibility of condensate splashing out of opening 301.

[0071] like Figure 7 As shown, in some embodiments, the sidewall of the opening 301 may include a first sidewall 31, which is attached to the rear wall of the refrigeration chamber 101. The first sidewall 31 may be a straight plane, which allows for better contact and fixation to the rear wall of the refrigeration chamber 101, thereby providing stable support and positioning for the flow guide 3.

[0072] The sidewall of the opening 301 may further include a second sidewall 32, a third sidewall 33, and a fourth sidewall 34. The rear end of the second sidewall 32 is connected to one side of the first sidewall 31. The third sidewall 33 is disposed opposite to the front side of the first sidewall 31, and one side of the third sidewall 33 is connected to the second sidewall 32. The front end of the fourth sidewall 34 is connected to the side of the third sidewall 33 away from the second sidewall 32, and the rear end of the fourth sidewall 34 is connected to the side of the first sidewall 31 away from the second sidewall 32.

[0073] The first sidewall 31 is attached to the rear wall of the refrigeration compartment 101, providing stable support and positioning for the entire open structure 301. The first sidewall 31, the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 are connected sequentially to form a surrounding space. The tops of the first sidewall 31, the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 form the open structure 301. In the direction from bottom to top of the housing 1, the top of at least one of the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 extends obliquely towards the outer periphery of the open structure 301.

[0074] Specifically, the tops of the first sidewall 31, the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 form an opening 301, creating a receiving area with a certain volume. At least one of the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 extends obliquely towards the outer periphery of the opening 301, resulting in a structure where the opening area of ​​the opening 301 gradually increases from bottom to top along the housing 1. Simultaneously, because the tops of at least one of the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 extend obliquely towards the outer periphery of the opening 301, the interior of the guide member 3 forms an inclined structure. When condensate flows to the upper ends of the inclined second sidewall 32, the third sidewall 33, and the fourth sidewall 34, it can flow more smoothly into the interior of the opening 301 along the inclined surfaces, thereby improving the condensate receiving efficiency.

[0075] In some embodiments, the top ends of the second sidewall 32, the third sidewall 33, and the fourth sidewall 34 are all arranged to extend obliquely toward the outer periphery of the opening 301.

[0076] like Figure 8 As shown, in some embodiments, the flow guide 3 may include a fixed wall 35, and the flow guide 3 is fixedly connected to the side wall of the tank liner through the fixed wall 35.

[0077] The fixed wall 35 can be arranged to extend upward from the side wall of the opening 301, and the fixed wall 35 can also be arranged to extend upward from the top wall of the opening 301. The top wall of the first side wall 31 can extend upward to form the fixed wall 35. It should be noted that in some other embodiments, the fixed wall 35 can be arranged to extend outward from the outer side wall of the guide member 3.

[0078] The fixed wall 35 may be provided with a fixing hole 303, the connector may be inserted through the fixing hole 303, and the other end of the connector is inserted through the rear wall of the refrigeration chamber 101, thereby fixing the guide 3 in the refrigeration chamber 101.

[0079] In some embodiments, the fixing hole 303 is elongated, and its length extends along the height of the housing 1. The fixing wall 35 is fixedly connected to the rear wall of the refrigeration compartment 101 through the fixing hole 303.

[0080] Specifically, a fixed wall 35 is formed by extending upward from the side wall of the opening 301. The fixed wall 35 has a fixing hole 303 that allows the connector to pass through and thus fix the fixed wall 35 to the rear wall of the refrigeration chamber 101. This avoids forming a fixing hole 303 in the space inside the flow guide 3, so that the fixing hole 303 and the space inside the flow guide 3 are aligned.

[0081] Furthermore, the elongated fixing hole 303 provided on the fixed wall 35 provides adjustment space for installation. When connecting to the rear wall of the refrigeration compartment 101 using bolts or other connectors passing through the fixing hole 303, the connectors can move up and down within the length range of the fixing hole 303, thus adjusting the position of the guide element 3 in the height direction, because the fixing hole 303 is elongated and extends along the height direction of the housing 1. In this way, the structure of the guide element 3 can be adapted to different models of refrigeration devices or refrigeration ducts 200 with different assembly dimensions of the guide element 3, improving the versatility of the guide element 3.

[0082] like Figure 8 As shown, in some embodiments, the rear wall of the refrigeration chamber 101 may be provided with a positioning hole (not shown in the figure). The outer wall of the flow guide 3 may be provided with a positioning post 36, which is located on the side of the flow guide 3 facing the rear wall of the refrigeration chamber 101. The positioning post 36 is inserted into the limiting hole. By providing a positioning post 36 on the outer wall of the flow guide 3, the positioning post 36 can be inserted into the limiting hole, thereby playing a role in pre-positioning the flow guide 3. Then, the connecting piece passes through the fixing hole 303 and is connected to the rear wall of the refrigeration chamber 101, which improves the installation efficiency.

[0083] like Figure 6 and Figure 8 As shown, in some embodiments, a first connecting rib 371 and a second connecting rib 372 are provided on the outer wall of the liquid outlet 302. The first connecting rib 371 and the second connecting rib 372 are respectively provided on opposite sides of the outer wall of the liquid outlet 302, and the first connecting rib 371 and the second connecting rib 372 are arranged at intervals along the height direction of the liquid outlet 302; the upper end of the drain pipe 4 is sleeved on the outer wall of the liquid outlet 302 and covers the outside of the first connecting rib 371 and the second connecting rib 372.

[0084] During the operation of the refrigeration device, the connection between the drain pipe 4 and the liquid outlet 302 needs to be kept secure to prevent condensate leakage. In this embodiment, by providing a first connecting rib 371 and a second connecting rib 372 on the outer wall of the liquid outlet 302, the upper end of the drain pipe 4 is sleeved on the outer wall of the liquid outlet 302 and thus covers the surface of the first connecting rib 371 and the second connecting rib 372, thereby enhancing the connection strength between the drain pipe 4 and the liquid outlet 302 and preventing the connection between the drain pipe 4 and the liquid outlet 302 from loosening due to factors such as vibration and temperature changes.

[0085] The drain pipe 4 is generally made of soft tubing. In order to further increase the connection stability between the drain pipe 4 and the liquid outlet 302, a first connecting rib 371 and a second connecting rib 372 are provided on the surface of the liquid outlet 302. The first connecting rib 371 and the second connecting rib 372 can provide additional fixing points for the drain pipe 4 and increase the friction between the drain pipe 4 and the outer wall of the liquid outlet 302. During the use of the refrigeration device, even if it is subjected to other external forces, the drain pipe 4 can maintain a stable connection with the liquid outlet 302.

[0086] In some embodiments, multiple first connecting ribs 371 may be provided, and the multiple first connecting ribs 371 may be arranged at intervals along the outer surface of the liquid outlet in the height direction. Multiple second connecting ribs 372 may be provided, and the multiple second connecting ribs 372 may be arranged at intervals along the outer surface of the liquid outlet in the height direction. The first connecting ribs 371 and the second connecting ribs 372 may be arranged alternately.

[0087] like Figure 2 and Figure 3 As shown, in some embodiments, the refrigeration device may include shelves 6 for supporting products to be refrigerated within the refrigeration compartment 101. Multiple shelves 6 may be provided, and these shelves 6 may be spaced apart along the height of the housing 1. The rear end of each shelf 6 is fixed to a cover plate 5.

[0088] By arranging multiple shelves 6 at intervals along the height of the cabinet 1, the space in the vertical direction of the refrigeration unit can be fully utilized, thereby dividing the internal space into multiple storage areas of different heights and improving space utilization.

[0089] The shelf 6 can be supported on two opposing side walls inside the refrigeration compartment 101. The rear end of the shelf 6 is fixed to the cover plate 5. The connection between the cover plate 5 and the rear wall of the refrigeration compartment 101 provides structural support for the shelf 6, effectively distributing the weight of the shelf 6 and the items on it, reducing deformation and swaying. By installing the cover plate 5, not only can the drain pipe 4 be concealed to maintain the aesthetics of the refrigeration compartment 101, but the shelf 6 can also be supported, improving its stability.

[0090] In some embodiments, the shelf 6 may include a left support portion 61 and a right support portion 62, which are arranged adjacent to each other. The side of the left support portion 61 closest to the right support portion 62 is fixed to the left side of the front wall of the cover plate 5. The side of the right support portion 62 closest to the left support portion 61 is fixed to the right side of the front wall of the cover plate 5.

[0091] In some large-capacity freezer structures, where the lateral dimensions are relatively large, the left and right support sections 61 and 62 are provided. The front wall of the cover 5 can support these sections respectively. Compared to a single-point fixation in the middle of the shelf 6, this increases the support force on the shelf 6, improves the even distribution of weight, and prevents bending or breakage due to excessive localized stress. The cover 5 not only conceals the drain pipe 4 but also provides support for the left and right support sections 61 and 62.

[0092] Figure 9 for Figure 3 Schematic diagram of the middle cover plate; Figure 10 for Figure 3 A schematic diagram of the layout of the central cover plate and the shelving.

[0093] like Figure 9 and Figure 10 As shown, in some embodiments, the refrigeration device may include support hooks 51, which are disposed on the front wall of the cover plate 5. Multiple support hooks 51 are provided, spaced apart along the height direction of the cover plate 5. The support hooks 51 can correspond to the installation height of the shelf 6, and are detachably disposed on the front wall of the cover plate 5, allowing the user to flexibly adjust the installation height of the shelf 6 according to actual needs, thereby better accommodating the storage of items of different sizes and improving the utilization rate of the internal space of the refrigeration device.

[0094] The rear end of the shelf 6 is provided with a slot 601, which is correspondingly set with the support hook 51. The shelf 6 is hooked onto the support hook 51 through the slot 601.

[0095] The rear end of the shelf 6 is provided with a slot 601 corresponding to the support hook 51, allowing the shelf 6 to be detachably connected to the support hook 51 on the cover plate 5. Users simply align the slot 601 at the rear end of the shelf 6 with the support hook 51 on the cover plate 5 and gently press or push the shelf 6 downwards to complete the installation. Similarly, disassembly is as simple as lifting the shelf 6 upwards to detach it from the support hook 51. This allows for quick and easy installation and disassembly of the shelf 6, improving the user experience. Furthermore, the slot 601 of the shelf 6 engaging with the support hook 51 also provides some support, preventing the shelf 6 from shaking or falling off.

[0096] like Figure 1 and Figure 2As shown, in some embodiments, the refrigeration device may include a first door 13 and a second door 14, which are arranged adjacent to each other on the left and right sides, and cover the opening of the refrigeration compartment 101. A cover plate 5 is correspondingly provided on the rear side of the first door 13 and the second door 14 arranged adjacent to each other.

[0097] The refrigeration unit can be configured as a double-door refrigerator. The double-door refrigerator is provided with a first door 13 and a second door 14 arranged adjacent to each other on the left and right sides. Correspondingly, the left support part 61 can be provided on the back of the first door 13, and the right support part 62 can be provided on the back of the second door 14.

[0098] The cover plate 5 is arranged adjacent to the rear side of the first door 13 and the second door 14. The mounting cavity 501 formed between the cover plate 5 and the rear wall of the refrigeration chamber 101 is located adjacent to the rear side of the first door 13 and the second door 14. That is, the drain pipe 4 can be arranged adjacent to the rear side of the first door 13 and the second door 14. Furthermore, a drain port 201 is provided at the middle position of the rear end of the refrigeration duct 200 corresponding to the two doors. The condensate in the refrigeration duct 200 can be collected at the middle position and then dripped into the guide member 3 through the drain port 201, and flow to the drain pipe 4 through the guide member 3. This can improve the efficiency of condensate discharge from the refrigeration duct 200 and avoid the drain pipe 4 of the refrigeration duct 200 being arranged on one side of the refrigeration duct 200 and the refrigeration chamber 101, which would increase the time for condensate to be discharged from the refrigeration duct 200.

[0099] 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.
