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, a freezer has a refrigeration compartment inside, which creates a refrigerated environment for storing goods.

[0003] Temperature control inside a freezer is typically achieved by controlling the compressor. Existing inverter freezers' compressors can automatically adjust their operating frequency and speed based on temperature changes inside the freezer, thus achieving more precise temperature control and more efficient energy utilization.

[0004] Currently, the compressor's display and control devices are exposed on the side wall of the housing, and some are located inside the compressor compartment. Generally, the display section of the display and control device is exposed at the mounting port of the housing, allowing users to observe and adjust parameters. Typically, the overall size of the display and control device is limited by the size of the mounting port, resulting in limited internal space. This makes it difficult to add or arrange components for the display and control device, and also hinders the integration of more functional modules or upgrades to the hardware configuration. Utility Model Content

[0005] The purpose of this utility model is to provide a cooling device that can increase the capacity of the display and control device by forming a second space extending towards the mounting port side inside the housing of the display and control device as an expansion space.

[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, with an installation opening on the outer wall of the housing; a display and control device disposed within the housing, the display and control device comprising: a shell disposed within the housing, the shell having a panel portion fitted into the installation opening; a control board disposed inside the shell, the control board being spaced apart on the inner side of the panel portion; and a receiving space formed inside the shell, the receiving space comprising: a first space formed on the inner side of the panel portion; and a second space extending from the first space toward the installation opening; wherein the first space and the second space are connected, the first space is arranged opposite to the installation opening, and the second space is located outside the installation opening, a portion of the control board is disposed within the first space, and another portion of the control board is disposed within the second space.

[0008] The above technical solution has the following advantages or beneficial effects: By designing the internal accommodating space of the housing as a first space and a second space, the first space is arranged opposite to the inner side of the panel, and the second space extends from the first space toward the mounting opening, serving as an expansion space formed outside the mounting opening. Compared to the prior art where the display and control device is limited by the size of the mounting opening, resulting in cramped internal space and restricted component arrangement, in this solution, the first space is adjacent to the inner side of the panel, and part of the control board can be installed in the first space, thus providing accommodating space for the part where the control board interacts with the panel. The second space extends outward toward the mounting opening to form an additional expansion area, which can accommodate larger components or components with special heat dissipation requirements. Specifically, after the compressor's display and controller are integrated into the display and control device, the separate inverter board components can be integrated onto the control board. The increased volume of the control board can be accommodated in the second space, thus achieving a larger display and control device arrangement without increasing the outer casing opening, giving the display and control device housing a relatively large accommodating space and providing the possibility for the installation of more components.

[0009] In some embodiments of this application, a refrigeration device is provided, wherein the housing has a first sidewall and a second sidewall disposed opposite to each other, the first sidewall and the second sidewall being respectively disposed on opposite sides of the panel portion; the first sidewall is formed on the side of the first space away from the second space, and the second sidewall is formed on the side of the second space away from the first space; a first clearance groove is recessed on the outer wall of the side of the second sidewall near the panel portion, the first clearance groove being disposed between the side of the second space facing the mounting opening and the first space.

[0010] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: By providing a first clearance groove on the side of the second sidewall near the panel, and the first clearance groove being correspondingly distributed between the side of the second space facing the mounting opening and the first space, the side of the second space near the mounting opening and the panel are spaced apart. When the size of the mounting opening is small and the size of the display and control device is large, the first clearance groove can provide additional operating space for the installation of the display and control device. When the display and control device is installed inside the housing from the front side of the mounting opening, the part of the housing corresponding to the second space can be inserted into the housing through the mounting opening first, and the first clearance groove is formed in the clearance space between the panel and the housing corresponding to the second space. The installer can more easily send the display and control device into the housing through the mounting opening, reducing the collision and friction between the display and control device and the sidewall of the mounting opening and the process of repeated adjustments, thereby improving the installation efficiency.

[0011] In some embodiments of this application, a refrigeration device is provided, wherein a first fixing part is provided on the side of the outer wall of the first sidewall near the panel portion; a second fixing part is provided on the side of the outer wall of the second sidewall near the panel portion, and the second fixing part is located in the first clearance groove; when the panel portion is installed at the mounting port, the peripheral edge of the mounting port near the first sidewall is engaged between the first fixing part and the panel portion, and the peripheral edge of the mounting port near the second sidewall is engaged between the second fixing part and the panel portion.

[0012] Another technical solution described above has the following advantages or beneficial effects: By providing a first fixing part on the first side wall and a second fixing part on the second side wall, one side of the mounting opening can be engaged between the first fixing part and the panel, and the other side of the mounting opening can be engaged between the second fixing part and the panel, thereby providing a stable fixing point for the panel and effectively preventing displacement or shaking of the panel in any direction. For example, during the operation of the refrigeration equipment, the vibration generated by the compressor may be transmitted to the panel. The double-sided engaging structure can disperse these vibration forces, ensuring that the panel and the display and control device remain stable, effectively reducing problems such as loose connections caused by vibration.

[0013] In some embodiments of this application, a refrigeration device is provided, wherein the second fixing part is configured as a fixing arm, one end of the fixing arm is connected to the second sidewall, and the other end of the fixing arm extends toward a side away from the first sidewall; the first fixing part is configured as an elastic arm, one end of the elastic arm is connected to the first sidewall, and the other end of the elastic arm extends toward a side of the panel portion; when the panel portion is installed at the mounting opening, the elastic arm elastically abuts against the peripheral edge of the mounting opening near the first sidewall.

[0014] Another technical solution described above has the following advantages or beneficial effects: During the installation of the display and control device, the installer can align and insert the peripheral edge of the mounting port between the fixed arm and the panel. At this time, the fit between the fixed arm and the peripheral edge of the mounting port provides a fixed fulcrum for the installation of the display and control device. During the process of the display and control device extending into the housing, the fit position between the fixed arm and the peripheral edge of the mounting port can be used as the rotation center, allowing the display and control device to rotate around this center, thereby causing the housing portion, which is larger than the mounting port, to rotate and extend into the housing. When installed in place, the peripheral edge of the mounting port near the first sidewall is inserted between the elastic arm and the panel, and the elastic arm and the peripheral edge of the mounting port are elastically connected. Thus, through the elastic adjustment of the elastic arm itself, the panel and the peripheral edge of the mounting port form a good fit and engagement, thereby allowing the panel to better adapt to the fit with the mounting port. Furthermore, the elastic force of the elastic arm can continuously apply pre-tightening force to the peripheral edge of the mounting port, so that the peripheral edge of the mounting port is clamped between the panel and the elastic arm, making the panel and the mounting port fit tightly together.

[0015] In some embodiments of this application, a cooling device is provided, wherein a second clearance groove is recessed on the outer wall of the first sidewall, and the second clearance groove is disposed on the side of the elastic arm away from the panel portion.

[0016] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: Because the display and control device has an extended second space as an expansion installation space, the overall size of the display and control device is larger than the size of the mounting port, which can easily cause interference with the peripheral edge of the mounting port during the installation of the wired control device. Specifically, the installer can align and insert the peripheral edge of the mounting port between the fixed arm and the panel, and use the mating position of the fixed arm and the peripheral edge of the mounting port as the rotation center, so that the display and control device rotates around the rotation center, thereby causing the housing part, which is larger than the mounting port, to rotate and extend into the cabinet. During this process, the second clearance groove formed by the recess of the first side wall can form a clearance space for the mating between the first side wall and the mounting port, so as to prevent interference between the outermost part of the display device and the mounting port when the entire display and control device rotates around the rotation center and extends into the cabinet.

[0017] In some embodiments of this application, a cooling device is provided, wherein a third sidewall is formed on the side of the housing away from the panel portion, and the third sidewall is connected between the first sidewall and the second sidewall;

[0018] An inclined wall is provided between the first sidewall and the third sidewall, and the inclined wall is located between the second clearance groove and the third sidewall.

[0019] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by providing an inclined wall between the second clearance groove and the third side wall, the inclined wall makes one side of the first side wall of the display and control device form a clearance space. Compared with the second side wall and the third side wall being set at a right angle or other angles, the setting of the inclined wall can effectively avoid interference between the display and control device and other components and the installation port during the installation process, thereby preventing collision or squeezing between the housing and the installation port, reducing the installation difficulty, and improving the installation efficiency.

[0020] In some embodiments of this application, a cooling device is provided, wherein the panel is provided with a display port that communicates with the first space; a display element is provided on the side of the control board facing the panel, the display element is located in the first space and is arranged opposite to the display port, and one end of the display element away from the control board is installed in the display port and exposed on the panel.

[0021] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by arranging the display component in the first space and opposite to the display port, the display component can be exposed on the cabinet through the display port, and the user can directly and clearly observe the display content of the display component through the display port.

[0022] In some embodiments of this application, a cooling device is provided, wherein a touch control is provided on the side of the control panel facing the panel portion, and the touch control is spaced apart on the inner side of the panel portion; the panel portion is provided with a button portion, the button portion is arranged opposite to the touch control, the button portion is columnar, and the columnar button portion extends toward the touch control; when the button portion is pressed, the end of the button portion near the touch control can abut against the touch control.

[0023] Another technical solution described above has the following advantages or beneficial effects: the user can trigger the control function of the display and control device by abutting the button on the panel against the touch control. Since a first recessed groove is provided on the outer wall of the second sidewall near the panel, and the first recessed groove is located between the side of the second space facing the mounting opening and the first space, the control board needs to extend and be arranged in the first and second spaces, thus requiring a gap between the control board and the panel. By setting the button in a columnar shape, the columnar button can extend from the panel towards the control board, thus ensuring that the button can effectively contact and abut against the touch control.

[0024] In some embodiments of this application, a refrigeration device is provided, wherein a gap area is formed between the control board and the panel portion, the gap area is arranged opposite to the first clearance groove, and the gap area is disposed in the first space; a fixing post is provided on the side of the panel portion facing the control board, the fixing post is disposed in the gap area, the fixing post extends toward the control board, and one end of the fixing post is connected to the control board.

[0025] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: by arranging the fixing posts in the interval area and extending them toward the control panel for connection, not only can the interval setting between the control panel and the panel be positioned, but the control panel can also be supported, preventing the button from moving against the control panel when the user presses the button, or preventing the control panel from shifting, loosening, or being damaged due to vibration, impact, or other factors during long-term use, thereby achieving reliable fixation between the panel and the control panel.

[0026] In some embodiments of this application, a refrigeration device is provided, wherein the outer wall of the housing is provided with a first outlet hole and a second outlet hole, the first outlet hole and the second outlet hole having different sizes; a sealing plate is provided at the second outlet hole, one end of the sealing plate is connected to the peripheral edge of the second outlet hole, and the other end of the sealing plate extends toward the second outlet hole to cover the second outlet hole; a bending groove is provided at the connection between the sealing plate and the peripheral edge of the second outlet hole.

[0027] Another technical solution described above has the following advantages or beneficial effects: By providing a sealing plate at the second cable outlet, with one end connected to the peripheral edge of the second cable outlet and the other end extending towards the second cable outlet, the unused or unnecessary second cable outlet is blocked. By blocking the second cable outlet with the sealing plate, on the one hand, the overall appearance and aesthetics of the housing are improved when the second cable outlet is not in use. On the other hand, a bending groove is provided at the connection between the sealing plate and the peripheral edge of the second cable outlet. When the second cable outlet is actually needed, the sealing plate can be broken or folded along the bending groove to expose the second cable outlet for cable passage. The bending groove allows for convenient and quick operation of the sealing plate when it needs to be opened, avoiding the cumbersome operation caused by complex disassembly structures such as screws and nuts, improving the versatility of the display and control device, and thus adapting to more refrigeration devices of different sizes and types.

[0048] The refrigeration device in the embodiments of the present invention can be a freezer, refrigerator or other refrigeration cabinet. The following uses a freezer as an example to describe in detail the improved technical solution of the refrigeration device in the embodiments of the invention.

[0049] Figure 1 This is a schematic diagram of a refrigeration device according to an embodiment of this application.

[0050] like Figure 1As shown, the refrigerator provided in this embodiment of the present invention includes a cabinet 1. The cabinet 1 can adopt a hollow structure such as a cuboid. The cabinet 1 forms the outer shell of the refrigeration device. It should be noted that the cabinet 1 can also adopt a hollow shell 21 structure of other shapes.

[0051] like Figure 1 As shown, in some embodiments, the interior of the housing 1 forms a refrigeration chamber (not shown in the figure). The top of the refrigeration chamber may have an opening. Multiple refrigeration chambers may be provided.

[0052] In some embodiments, multiple refrigeration compartments can serve as independent storage spaces, such as freezers, refrigerators, and variable-temperature compartments, to meet different refrigeration needs, such as freezing, refrigeration, and variable-temperature storage, depending on the type of food, and to store items that require refrigeration or freezing. Multiple refrigeration compartments can be arranged vertically or horizontally.

[0053] In some embodiments, the refrigeration device may include a liner (not shown in the figure). The liner may be disposed inside the housing 1. The liner contains a refrigeration compartment.

[0054] like Figure 1 As shown, in some embodiments, the refrigeration unit includes a door 11. The door 11 is located on the front side of the housing 1 for opening and closing the refrigeration compartment.

[0055] It should be noted that multiple doors 11 can be installed. Each door 11 can be installed in a one-to-one correspondence with a refrigeration room. Multiple doors 11 can open and close a single refrigeration room simultaneously. A single door 11 can also open and close multiple refrigeration rooms simultaneously.

[0056] Figure 2 for Figure 1 A cross-sectional schematic diagram.

[0057] like Figure 2 As shown, in some embodiments, the refrigeration system may include a compressor 12. The compressor 12, as the power source of the refrigeration cycle, draws in low-temperature, low-pressure refrigerant gas and compresses it into high-temperature, high-pressure gas. The compressor 12 can deliver the high-temperature, high-pressure refrigerant to the condenser.

[0058] like Figure 2 As shown, in some embodiments, a compressor compartment 102 may be provided inside the housing 1. The compressor 12 may be arranged inside the compressor compartment 102.

[0059] In some embodiments, the refrigeration system may include a condenser (not shown). The condenser may be used to receive refrigerant flowing out of compressor 12, cooling the high-temperature, high-pressure refrigerant gas from compressor 12 and converting it into a liquid state. The condenser may transfer heat from the refrigerant to the surrounding air, thereby lowering the temperature of the refrigerant.

[0060] In some embodiments, the refrigeration system may include a throttling device (not shown). A condenser can deliver 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.

[0061] In some embodiments, the refrigeration system may include an evaporator (not shown). A throttling device may deliver a throttled and depressurized refrigerant into the evaporator. The evaporator may be used for the refrigerant vapor to evaporate and boil, thereby absorbing heat from the surrounding medium.

[0062] In some embodiments, the compressor 12, condenser, throttling device, and evaporator 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.

[0063] Figure 3 for Figure 1 A partial exploded view in the image; Figure 4 for Figure 3 A magnified view of part A.

[0064] like Figure 1 and Figure 3 As shown, in some embodiments, the refrigeration device includes a display and control device 2. The display and control device 2 is disposed inside the housing 1. The display and control device 2 may have display and control functions, and the display device may be used to make electrical connections with the components inside the refrigeration device.

[0065] like Figure 4 As shown, in some embodiments, the display and control device 2 may include a housing 21. The housing 21 is disposed inside the enclosure 1. The housing 21 can accommodate the internal parts of the display and control device 2. The housing 21 has a panel portion 22, and the outer wall of the enclosure 1 has a mounting opening 101, into which the panel portion 22 can be fitted.

[0066] In this method, by embedding the panel 22 into the mounting opening 101 of the housing 1, that is, by exposing the panel 22 on the housing 1, the embedding installation method makes the panel 22 and the surface of the housing 1 relatively flat.

[0067] like Figure 3 As shown, in some embodiments, the mounting port 101 can be connected to the compressor compartment 102. The display and control device 2 can be electrically connected to the compressor compartment 102 and the compressor 12, thereby controlling the operating state of the compressor 12 to regulate the temperature of the refrigeration unit.

[0068] like Figure 4As shown, in some embodiments, the display and control device 2 may include a control board 23. The control board 23 is disposed inside the housing 21. The panel 22 may be connected to the control board 23, and the control board 23 may be electrically connected to the compressor 12. During operation, the user can control the control board 23 through the panel 22 to adjust the working state of the compressor 12.

[0069] like Figure 4 As shown, in some embodiments, a receiving space 201 is formed inside the housing 21. The receiving space 201 may include a first space 2011 and a second space 2012. The first space 2011 is formed on the inner side of the panel portion 22. The second space 2012 extends from the first space 2011 toward the mounting opening 101. The first space 2011 and the second space 2012 are connected, the first space 2011 is arranged opposite to the mounting opening 101, and the second space 2012 is located on the outer side of the mounting opening 101. A control plate 23 is spaced apart on the inner side of the panel portion 22, with a portion of the control plate 23 arranged in the first space 2011 and another portion of the control plate 23 arranged in the second space 2012.

[0070] Specifically, the first space 2011 is formed inside the mounting opening 101 and is arranged opposite to the mounting opening 101. In this way, the panel 22 can directly contact the control board 23 through the first space 2011 and thus control the control board 23. Furthermore, by forming the first space 2011 and the second space 2012 that are interconnected inside the housing 21, and the second space 2012 extends from the first space 2011 toward the mounting opening 101 and is located outside the mounting opening 101, the second space 2012 can serve as an expansion space, thereby overcoming the limitation of the size of the mounting opening 101 on the internal storage space 201 of the display and control device 2. In this embodiment, by spaced-apartly arranging the control boards 23 inside the panel portion 22, the control boards 23 can be located at the connection between the first space 2011 and the second space 2012. Thus, the control boards 23 for circuit modules that need direct interaction with the panel portion 22 are installed in the first space 2011, while another part of the control boards 23 extends into the second space 2012 through the connection between the first space 2011 and the second space 2012. The second space 2012 serves as an expansion space, providing more installation space for components within the display and control device 2. Even with a limited mounting opening 101, the display and control device 2 can still have a relatively large accommodating space 201 inside the housing 21, making it possible to install more components.

[0071] Currently, the inverter board controlling the compressor 12 and the display board for temperature regulation and display are installed separately on the freezer. This separate installation requires additional inverter board boxes, wiring harnesses, connectors, and other components. The separate installation and wiring of the controller and display also increase labor costs and assembly time. Integrating the controller and display into a single unit, forming a display device 2, would effectively eliminate the need for the inverter box and inverter board on the cabinet 1. However, correspondingly, the display device 2 would be larger than a single controller and display unit.

[0072] However, the display and control device 2 of the compressor 12 is exposed on the side wall of the housing 1 and is partially distributed inside the compressor compartment 102. Generally, the display of the display and control device 2 is exposed on the mounting port 101 of the housing 1, allowing the user to observe and adjust the parameters. Generally, the overall size of the display and control device 2 is limited by the size of the mounting port 101, which in turn affects the internal storage space 201 of the display device, making it inconvenient to add and arrange the components of the display and control device 2.

[0073] In this application, the internal accommodating space 201 of the housing 21 is designed as a first space 2011 and a second space 2012. The first space 2011 is arranged opposite to the inner side of the panel 22, and the second space 2012 extends from the first space 2011 toward the mounting opening 101, serving as an expansion space formed outside the mounting opening 101. Compared to the prior art where the display and control device 2 is limited by the size of the mounting opening 101, resulting in cramped internal space and restricted component arrangement, in this solution, the first space 2011 is adjacent to the inner side of the panel 22, and part of the control board 23 can be installed within the first space 2011, thus providing accommodating space for the part where the control board 23 interacts with the panel 22. The second space 2012 extends outward toward the mounting opening 101 to form an additional expansion area, which can accommodate larger components or components with special heat dissipation requirements. Specifically, after the display and controller of the compressor 12 are integrated into the display and control device 2, the separate frequency converter board components can be integrated into the control board 23. The increased volume of the control board 23 can be accommodated in the second space 2012. Thus, without increasing the opening of the outer casing, a larger display and control device 2 can be arranged, so that the interior of the display and control device 2 housing 21 has a relatively large accommodating space 201, which makes it possible to install more components.

[0074] like Figure 4 As shown, in some embodiments, the second space 2012 may extend from the first space 2011 toward the lower side of the mounting port 101. It should be noted that the second space 2012 may also extend from the first space 2011 toward the upper side of the mounting port 101, or toward one of the left or right sides, or in other directions.

[0075] like Figure 4 As shown, in some embodiments, the housing 21 may include a front housing 2110 and a rear housing 2120. The front housing 2110 and the rear housing 2120 are connected and together enclose the aforementioned receiving space 201. A first space 2011 may be formed in the upper part of the front housing 2110 and the rear housing 2120, and a second space 2012 may be formed in the lower part of the front housing 2110 and the rear housing 2120. The panel portion 22 may be disposed on the side of the front housing 2110 away from the rear housing 2120.

[0076] Figure 5 for Figure 2 A three-dimensional schematic diagram of the central display and control device; Figure 6 for Figure 5 A cross-sectional view; Figure 7 for Figure 5 A cross-sectional view from another perspective.

[0077] like Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the housing 21 may have a first sidewall 211 and a second sidewall 212 disposed opposite to each other, the first sidewall 211 and the second sidewall 212 being disposed on opposite sides of the panel portion 22; the first sidewall 211 is formed on the side of the first space 2011 away from the second space 2012, and the second sidewall 212 is formed on the side of the second space 2012 away from the first space 2011. A first clearance groove 202 is recessed on the outer wall of the side of the second sidewall 212 near the panel portion 22, the first clearance groove 202 being disposed between the side of the second space 2012 facing the mounting opening 101 and the first space 2011.

[0078] The first sidewall 211 and the second sidewall 212 are respectively disposed on opposite sides of the panel portion 22, that is, the first sidewall 211 and the second sidewall 212 are respectively disposed on opposite sides of the mounting opening 101. Specifically, the first sidewall 211 and the second sidewall 212 can be disposed on the upper and lower sides or the left and right sides of the panel portion 22, etc. In this embodiment, the first sidewall 211 and the second sidewall 212 are distributed on the upper and lower sides of the panel portion 22 as an example. Correspondingly, the second space 2012 extends downward from the lower end of the first space 2011 and is arranged with the first space 2011. The first sidewall 211 of the housing 21 is formed on the side of the first space 2011 away from the second space 2012, that is, the first sidewall 211 is disposed on the top of the first space 2011, and the second sidewall 212 of the housing 21 is formed on the side of the second space 2012 away from the first space 2011, that is, the second sidewall is disposed on the bottom of the second space 2012.

[0079] In this embodiment, a first recessed groove 202 is provided on the side of the second sidewall 212 near the panel portion 22. The first recessed groove 202 is correspondingly distributed between the side of the second space 2012 facing the mounting port 101 and the first space 2011, so that the side of the second space 2012 near the mounting port 101 is spaced apart from the panel portion 22. When the size of the mounting port 101 is small and the size of the display and control device is large, the first clearance groove 202 can provide additional operating space for the installation of the display and control device 2. When the display and control device 2 is installed inside the housing 1 from the front side of the mounting port 101, the part of the housing 21 corresponding to the second space 2012 can be inserted into the housing 1 through the mounting port 101. The first clearance groove 202 is formed in the clearance space between the panel part 22 and the housing 21 corresponding to the second space 2012. The installer can more easily send the display and control device 2 into the housing 21 through the mounting port 101, reducing the process of repeated adjustment due to collision between the display and control device 2 and the side wall of the mounting port 101, thereby improving the installation efficiency.

[0080] like Figure 6 and Figure 7 As shown, in some embodiments, the first clearance groove 202 can be a stepped groove. The outer wall of the second sidewall 212 forms a stepped structure, and the first clearance groove 202 can be formed on the stepped structure to form a clearance space.

[0081] In some other embodiments, the first clearance groove 202 may be positioned as a notch structure of other shapes. For example, the outer wall of the second sidewall 212 may be concave to form an arc-shaped groove on the side facing the first sidewall 211.

[0082] In some other embodiments, the display and control device 2 can extend into the press chamber 102 from the opening at the rear of the press chamber 102 and embed the two panel portions 22 at the mounting opening 101.

[0083] Figure 8 for Figure 2 A cross-sectional view of the installation state; Figure 9 for Figure 8 A magnified view of section B.

[0084] like Figure 6 , Figure 8 and Figure 9As shown, in some embodiments, a second fixing part 25 may be provided on the side of the outer wall of the second sidewall 212 near the panel portion 22. The second fixing part 25 is located within the first recess groove 202. A first fixing part 24 may be provided on the side of the outer wall of the first sidewall 211 near the panel portion 22. When the panel portion 22 is installed at the mounting opening 101, the peripheral edge of the mounting opening 101 near the first sidewall 211 engages between the first fixing part 24 and the panel portion 22, and the peripheral edge of the mounting opening 101 near the second sidewall 212 engages between the second fixing part 25 and the panel portion 22.

[0085] By placing the second fixing part 25 within the first recess 202, a positioning reference can be provided for the installation of the panel part 22. During installation, the installer can align the first recess 202 with the peripheral edge of the mounting opening 101, and then insert the display and control device 2 through the mounting opening 101 into the interior of the housing 1. Specifically, the installer can engage the peripheral wall of the mounting opening 101 between the second fixing part 25 and the panel part 22, and then rotate the display and control device 2 until the first space 2011 and the second space 2012 of the display and control device 2 are correspondingly arranged inside the housing 1. The peripheral edge of the mounting opening 101 near the first side wall 211 then engages between the first fixing part 24 and the panel part 22, thereby completing the installation of the panel part 22.

[0086] Furthermore, by providing a first fixing part 24 on the first side wall 211 and a second fixing part 25 on the second side wall 212, one side of the mounting opening 101 can be engaged between the first fixing part 24 and the panel part 22, and the other side of the mounting opening 101 can be engaged between the second fixing part 25 and the panel part 22. This provides a stable fixing point for the panel part 22, effectively preventing displacement or shaking of the panel part 22 in any direction. For example, during the operation of the refrigeration equipment, the vibration generated by the compressor 12 may be transmitted to the panel part 22. The double-sided engaging structure can disperse these vibration forces, ensuring that the panel part 22 and the display and control device 2 remain stable, effectively reducing problems such as loose connections caused by vibration.

[0087] In some embodiments, at least two first fixing parts 24 may be provided. The first fixing parts 24 are spaced apart to improve the installation strength between the display and control device 2 and the mounting port 101.

[0088] like Figure 6 and Figure 7 As shown, in some embodiments, the second fixing part 25 may be configured as a fixing arm. One end of the fixing arm is connected to the second sidewall 212, and the other end of the fixing arm extends toward the side away from the first sidewall 211.

[0089] The fixing arms can be arranged at intervals on the rear side of the panel portion 22, so that the peripheral edge of the mounting port 101 near the second side wall 212 can be engaged between the second fixing portion 25 and the panel portion 22.

[0090] like Figure 6 and Figure 7 As shown, in some embodiments, the first fixing part 24 may be configured as an elastic arm. One end of the elastic arm is connected to the first sidewall 211, and the other end of the elastic arm extends toward one side of the panel part 22. When the panel part 22 is installed at the mounting opening 101, the elastic arm elastically abuts against the peripheral edge of the mounting opening 101 near the first sidewall 211.

[0091] The other end of the elastic arm extends towards one side of the panel 22, forming a gap between it and the panel 22. By configuring the first fixing part 24 as an elastic arm, when the panel 22 is installed in place, the elastic force of the elastic arm can continuously apply a preload force to the peripheral edge of the mounting opening 101, so that the peripheral edge of the mounting opening 101 is clamped between the panel 22 and the elastic arm, making the panel 22 and the mounting opening 101 fit tightly together. The elastic arm effectively prevents the panel 22 from vibrating during the operation of the refrigeration device, which helps the display and control device 2 to always be in a stable working state.

[0092] like Figure 8 and Figure 9 As shown, further, during the installation of the display and control device 2, the installer can align and insert the peripheral edge of the mounting port 101 between the fixed arm and the panel portion 22. At this time, the cooperation between the fixed arm and the peripheral edge of the mounting port 101 can provide a fixed fulcrum for the installation of the display and control device 2. Then, the display and control device 2 is inserted into the housing 1 through the mounting port 101. During the insertion process, the display and control device 2 can be rotated around the cooperation position between the fixed arm and the peripheral edge of the mounting port 101 as the rotation center, thereby causing the housing portion 21, which is larger than the mounting port 101, to rotate and be inserted into the housing 1. When installed in place, the peripheral edge of the mounting port 101 near the first side wall 211 is inserted between the elastic arm and the panel portion 22, and the elastic arm is elastically connected to the peripheral edge of the mounting port 101. Thus, through the elastic adjustment of the elastic arm itself, the panel 22 and the peripheral edge of the mounting port 101 form a good fit and snap-fit, thereby enabling the panel 22 to better adapt to the fit with the mounting port 101.

[0093] like Figure 9 As shown, in some embodiments, the peripheral edge of the mounting opening 101 may be stepped. In this way, the peripheral edge of the mounting opening 101 can form a mounting groove 103, and the panel portion 22 can be fitted into the mounting groove 103.

[0094] like Figure 6 and Figure 9 As shown, in some embodiments, the outer wall of the first sidewall 211 may be recessed with a second clearance groove 203. The second clearance groove 203 is provided on the side of the elastic arm away from the panel portion 22. By recessing the second clearance groove 203 on the outer wall of the first sidewall 211, additional operating space can be provided for the installation of the display and control device 2.

[0095] Because the display and control device 2 has an extended second space 2012 as an expansion space for installation, the overall size of the display and control device 2 is larger than the size of the mounting opening 101. During the installation of the wired control device, it is easy for it to interfere with the peripheral edge of the mounting opening 101. Specifically, the installer can align and insert the peripheral edge of the mounting opening 101 between the fixing arm and the panel part 22, and use the cooperation position between the fixing arm and the peripheral edge of the mounting opening 101 as the rotation center. The display and control device 2 can be rotated around the rotation center, thereby causing the housing 21 part, which is larger than the mounting opening 101, to rotate and extend into the cabinet 1. During this process, the second clearance groove 203 formed by the recess of the first side wall 211 can provide clearance space between the first side wall 211 and the mounting opening 101, so as to prevent interference between the outermost part of the display device and the mounting opening 101 when the entire display and control device 2 rotates around the rotation center and extends into the cabinet 1.

[0096] Thus, the coordinated arrangement of the second clearance slot 203 and the first clearance slot 202 provides sufficient operating space for the installation and disassembly of the display and control device 2. The installer can easily remove it from the mounting port 101 or quickly install it on the mounting port 101, reducing the installation difficulty and improving the installation efficiency.

[0097] Furthermore, by adjusting the depth, width, and shape of the second clearance groove 203, sufficient clearance space can be provided to ensure that the display and control device 2 can be installed smoothly without interfering with the mounting port 101.

[0098] like Figure 6 and Figure 9 As shown, in some embodiments, the second clearance groove 203 can be a stepped groove. The outer wall of the first sidewall forms a stepped structure, and the second clearance groove 203 can be formed on the stepped structure to form a clearance space.

[0099] In some other embodiments, the second recess 203 may be positioned as a notch structure of other shapes. For example, the outer wall of the first sidewall 211 may be concave to form an arc-shaped groove on the side facing the second sidewall 212.

[0100] like Figure 6 and Figure 7As shown, in some embodiments, a third sidewall 213 may be formed on the side of the housing 21 away from the panel portion 22. The third sidewall 213 connects between the first sidewall 211 and the second sidewall 212. An inclined wall 214 is provided between the first sidewall 211 and the third sidewall 213. The inclined wall 214 is located between the second recess groove 203 and the third sidewall 213.

[0101] Specifically, the panel portion 22 can be the front side of the display and control device 2, and the third sidewall 213 can be arranged opposite to the rear side of the panel portion 22. The upper and lower ends of the third sidewall 213 are respectively connected to the sides of the first sidewall 211 and the second sidewall 212 away from the panel portion 22. The inclined wall 214 is disposed between the first sidewall 211 and the third sidewall 213 and is located between the second recess 203 and the third sidewall 213. In the direction from the panel portion 22 toward the third sidewall 213, the inclined wall 214 can be arranged to extend toward the side closer to the second sidewall 212. In this way, the side of the inclined wall 214 closer to the third sidewall 213 can be located inside the mounting opening 101.

[0102] Among them, by providing an inclined wall 214 between the second clearance groove 203 and the third side wall 213, the inclined wall 214 makes one side of the first side wall 211 of the display and control device 2 form a clearance space. Compared with the second side wall 212 and the third side wall 213 being set at a right angle or other angles, the setting of the inclined wall 214 can effectively avoid interference between the display and control device 2 and other components and the mounting port 101 during the installation process, thereby preventing collision or squeezing between the housing 21 and the mounting port 101. Furthermore, the inclined wall 214 allows a transition space to be formed between the second recess 203 and the third side wall 213. During the installation of the display and control device 2, as the display and control device 2 is rotated to extend into the interior of the housing 1, it can first pass through the recess space outside the inclined wall 214 and then transition to the second recess 203, ultimately placing the display and control device 2 inside the housing 1 and embedding the panel 22 into the mounting port 101. This further provides sufficient operating space for the installation and removal of the display and control device 2, allowing installers to easily remove it from the mounting port 101 or quickly install it on the mounting port 101, reducing installation difficulty and improving installation efficiency.

[0103] In some other embodiments, the inclined wall 214 may be a sidewall with an outer arc surface.

[0104] like Figure 5 and Figure 6As shown, in some embodiments, the panel portion 22 may be provided with a display port 204. The display port 204 communicates with the first space 2011. A display element 231 is provided on the side of the control board 23 facing the panel portion 22. The display element 231 is located in the first space 2011 and is arranged opposite to the display port 204. The end of the display element away from the control board 23 is installed in the display port 204 and exposed on the panel portion 22.

[0105] When the display and control device 2 is electrically connected to the compressor 12, the user can view the operating status of the refrigeration unit through the display component 231. Specifically, by arranging the display component 231 within the first space 2011 and opposite to the display port 204, the display component 231 is exposed on the housing 1 through the display port 204, allowing the user to directly and clearly observe the displayed content through the display port 204.

[0106] In some embodiments, a touch control 232 may be provided on the side of the control panel 23 facing the panel portion 22. The touch controls 232 are spaced apart on the inner side of the panel portion 22. The panel portion 22 may be provided with a button portion 26. The button portion 26 is arranged opposite to the touch control 232. The button portion 26 may be columnar. The columnar button portion 26 extends toward the touch control 232; when the button portion 26 is pressed, the end of the button portion 26 near the touch control 232 can abut against the touch control 232.

[0107] The user can trigger the control function of the display and control device 2 by abutting the button 26 on the panel 22 against the touch control 232. Since a first recessed groove 202 is provided on the outer wall of the second sidewall 212 near the panel 22, and the first recessed groove 202 is located between the side of the second space 2012 facing the mounting opening 101 and the first space 2011, the control board 23 needs to extend and be arranged on the first space 2011 and the second space 2012, thus requiring a gap between the control board 23 and the panel 22. By setting the button 26 in a columnar shape, the columnar button 26 can extend from the panel 22 towards the control board 23, thus ensuring that the button 26 can effectively contact and abut against the touch control 232.

[0108] like Figure 5 and Figure 7 As shown, in some embodiments, the panel portion 22 is provided with a cutout area 221. The cutout area can be distributed around the button portion 26, so that when the user presses the button portion 26, the button portion 26 can produce a certain elastic deformation, thereby effectively and reliably contacting and abutting against the touch control 232 which is spaced apart on the inner side of the panel portion 22.

[0109] like Figure 6 and Figure 7As shown, in some embodiments, a gap 205 may be formed between the control panel 23 and the panel portion 22, and the gap 205 is arranged opposite to the first clearance groove 202. The gap 205 is disposed within the first space 2011. A fixing post 27 may be fixed on the side of the panel portion 22 facing the control panel 23. The fixing post 27 is disposed in the gap 205. The fixing post 27 extends toward the control panel 23, and one end of the fixing post 27 is connected to the control panel 23.

[0110] Wherein, since the outer wall of the second sidewall 212 near the panel portion 22 is recessed with a first clearance groove 202, and the first clearance groove 202 is located between the side of the second space 2012 facing the mounting port 101 and the first space 2011, the control plate 23 and the panel portion 22 need to be arranged at intervals to form an interval area 205. The interval area 205 is arranged opposite to the first clearance groove 202, that is, the interval area 205 and the first clearance groove 202 are respectively formed on opposite sides of the second sidewall 212.

[0111] Furthermore, by arranging the fixing post 27 within the interval area 205 and extending the fixing post 27 toward the control plate 23 for connection, not only can the spacing between the control plate 23 and the panel 22 be positioned, but the control plate 23 can also be supported, preventing the button 26 from abutting against the control plate 23 when the user presses the button 26 and causing displacement, or preventing the control plate 23 from shifting, loosening, or being damaged due to vibration, impact, or other factors during long-term use, thereby achieving reliable fixation between the panel 22 and the control plate 23.

[0112] In some embodiments, the fixing post 27 may be provided with a connecting hole (not shown in the figure), and a connector (not shown in the figure) may be passed through the connecting hole to connect the fixing post 27 and the control plate 23 together.

[0113] like Figure 6 As shown, in some embodiments, a first stop rib 218 may be provided inside the housing 21. The first stop rib 218 may be arranged within the first space 2011 and located on the side of the control plate 23 facing the panel portion 22. The first stop rib 218 may restrain and limit the control plate 23 on the side near the panel portion 22.

[0114] like Figure 6 As shown, in some embodiments, a second stop rib 219 may be provided inside the housing 21. A first stop rib 218 may be arranged within the second space 2012 and located on the side of the control plate 23 away from the panel portion 22. The second stop rib 219 may restrain the control plate 23 on the side away from the panel portion 22.

[0115] Figure 10 for Figure 5A three-dimensional diagram from another perspective; Figure 11 for Figure 5 Rear view.

[0116] like Figure 10 and Figure 11 As shown, in some embodiments, the outer wall of the housing 21 may be provided with a first cable outlet 28. The first cable outlet 28 is used for the connecting wires inside the display and control device to extend into the housing 1.

[0117] In some embodiments, the first cable outlet 28 may be provided with a first cable outlet hole 206. The first cable outlet hole 206 may communicate with the first space 2011 or the second space 2012, thereby allowing the connecting wire inside the housing 21 to extend into the box 1.

[0118] like Figure 10 and Figure 11 As shown, in some embodiments, the first cable outlet 28 may be provided with a second cable outlet 207. The first cable outlet 206 and the second cable outlet 207 have different dimensions.

[0119] like Figure 11 As shown, specifically, the size of the second cable outlet 207 can be configured to be larger than the size of the first cable outlet 206. In this way, the first cable outlet 206 can be adapted to smaller diameter or fewer connecting cables, while the second cable outlet 207 can be used to adapt to larger diameter connecting cables or more cable bundles, so as to meet the differentiated requirements for cable outlet size in different application scenarios and improve the versatility and adaptability of the housing 21.

[0120] like Figure 10 and Figure 11 As shown, in some embodiments, a sealing plate 281 may be provided at the second outlet hole 207. One end of the sealing plate is connected to the peripheral edge of the second outlet hole 207, and the other end of the sealing plate extends toward the second outlet hole 207 to cover the second outlet hole 207. A bending groove 208 may be provided at the connection between the sealing plate and the peripheral edge of the second outlet hole 207.

[0121] Specifically, a sealing plate 281 is provided at the second cable outlet 207. One end of the sealing plate 281 is connected to the peripheral edge of the second cable outlet 207, and the other end extends toward the second cable outlet 207, thereby blocking the unused or unnecessary second cable outlet 207. By blocking the second cable outlet 207 with the sealing plate 281, the overall appearance and aesthetics of the housing 21 can be improved when the second cable outlet 207 is not in use.

[0122] On the other hand, a bending groove 208 is provided at the connection between the sealing plate 281 and the peripheral edge of the second cable outlet 207. When the second cable outlet 207 is needed, the sealing plate 281 can be broken or folded along the bending groove 208 to expose the second cable outlet 207 for cable passage. The bending groove 208 allows the sealing plate 281 to be opened conveniently and quickly, avoiding the cumbersome operation caused by complex disassembly structures such as screws and nuts. This improves the versatility of the display and control device 2, thus adapting it to more refrigeration devices of different sizes and types.

[0123] like Figure 10 As shown, in some embodiments, multiple second cable outlet holes 207 may be provided. Each of the multiple second cable outlet holes 207 is correspondingly provided with a sealing plate 281.

[0124] like Figure 11 As shown, in some embodiments, a connecting protrusion 282 may be provided between the side of the sealing plate 281 away from the bending groove 208 and the peripheral edge of the second cable outlet 207. The connecting protrusion 282 can fix the side of the sealing plate 281 away from the bending groove 208, and the sealing plate 281 can be stably connected to the housing 21 when the second cable outlet 207 is not needed.

[0125] like Figure 11 As shown, in some embodiments, two connecting protrusions 282 may be provided. The two connecting protrusions 282 may be respectively provided on opposite sides of the sealing plate 281, thereby enabling the sealing plate 281 to be stably connected to the housing.

[0126] like Figure 10 and Figure 11 As shown, in some embodiments, the outer wall of the housing 21 may be provided with a second cable outlet 29. The first cable outlet 28 and the second cable outlet 29 may be respectively located on both sides of the housing. This allows the connecting wires inside the display and control device 2 to extend to the housing 1 at different positions.

[0127] In some embodiments, the second cable outlet 29 may be provided with a third cable outlet 210. The size of the third cable outlet 210 may be different from that of the first cable outlet 206 and the second cable outlet 207. Figure 10 and Figure 11 As shown, in some embodiments, a water-retaining flange 215 may be provided on the outer wall of the housing 21. The water-retaining flange 215 may be arranged around the outside of the first cable outlet 206 and the second cable outlet 207. This can prevent water vapor inside the housing 1 from directly entering the display and control device 2 through the first cable outlet 206 and the second cable outlet 207.

[0128] like Figure 10 and Figure 11As shown, in some embodiments, the housing 21 also includes a heat dissipation part 216, which is protrudingly disposed on the side wall of the housing 21. A heat dissipation hole 209 is provided at the bottom end of the heat dissipation part 216, and the heat dissipation hole 209 communicates with the first space 2011 or the second space 2012.

[0129] By setting heat dissipation holes 209 and connecting them to the internal space of the housing 21, the heat in the first space 2011 or the second space 2012 can be released to the outside through the heat dissipation holes 209, thereby effectively reducing the heat accumulation generated by the electronic components inside the housing 21 during operation, improving the overall heat dissipation performance of the display and control device 2 or the cooling device, and ensuring that components such as the control board 23 and the display 231 operate stably within a suitable temperature range.

[0130] like Figure 10 and Figure 11 As shown, in some embodiments, the top of the heat dissipation part 216 may be provided with a flow guiding surface 217. In the direction from front to back of the housing 21, the flow guiding surface 217 extends downward at an angle, and the bottom end of the flow guiding surface 217 is located outside the heat dissipation hole 209.

[0131] When the display and control device 2 is electrically connected to the compressor 12, the display and control device 2 is arranged inside the compressor chamber 102. By providing a guide surface 217 on the top of the heat dissipation part 216, and the guide surface 217 extending downwards in the direction from front to back on the housing 21, the water vapor in the compressor chamber 102 can be guided to flow away from the heat dissipation hole 209 through the guide surface 217, thereby preventing the water vapor in the compressor chamber 102 from entering the display and control device 2.

[0132] 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.
