Description

Technical Field

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

[0002] Refrigerators, freezers, and other refrigeration equipment are containers that use the phase change of refrigerant to create a low-temperature environment for storing food and other items. They are one of the indispensable household appliances in people's daily lives.

[0003] Related refrigeration equipment typically includes a cabinet and a liner inside the cabinet, which forms a refrigeration compartment. A foaming cavity is formed between the interior of the cabinet and the exterior of the liner. Foaming material is poured into the foaming cavity, forming a foam layer. This foam layer enables the refrigerator to achieve its heat preservation and insulation performance.

[0004] During the foaming process of related refrigeration equipment, the foaming material is usually injected into the foaming cavity from the back of the box. The foaming material usually fills the two sides of the box first, which affects the filling quality of the top of the box. Utility Model Content

[0005] The purpose of this invention is to provide a refrigeration device that optimizes the foaming structure of the refrigeration device and improves the filling quality of the foaming material at the top of the box.

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

[0007] According to one aspect of the present invention, a refrigeration device is provided, comprising: a housing forming the outer shell of the refrigeration device; a liner disposed within the housing, the liner containing a refrigeration chamber; a foaming cavity formed between the outer surface of the liner and the interior of the housing; a first air duct structure disposed within the foaming cavity, the first air duct structure being spaced apart from the top region of the foaming cavity; a guide groove provided on the back side of the first air duct structure for receiving injected foaming material; the top end of the guide groove being open and facing the top of the housing, and the bottom end of the guide groove being open and facing the bottom of the housing; and two guide plates disposed on the top upper side of the first air duct structure, the two guide plates being disposed on opposite sides of the top opening of the guide groove; wherein a guide channel is formed between the two guide plates, one end of the guide channel communicating with the top opening of the guide groove, and the other end extending towards the top region of the foaming cavity.

[0008] The above technical solution has the following advantages or beneficial effects: By positioning the foaming material within the guide channel, the injected foaming material falls directly into the channel. The foaming material falling into the guide channel can move upwards along the channel, flowing through the top opening towards the top or sides of the foaming cavity, thus preferentially filling the top area of ​​the cavity. Alternatively, the foaming material can move downwards along the guide channel, flowing through the bottom opening towards the bottom or sides of the cavity. After injection into the guide channel, the foaming material can flow into the guide channel through the top opening, flowing along the guide channel towards the top area of ​​the foaming cavity, increasing the foaming filling speed of the top area of ​​the cavity, ensuring priority filling of the top area, improving the filling quality of the top of the cavity, and consequently improving the overall filling quality of the cavity's interior.

[0009] In some embodiments of this application, the back side of the first air duct structure is provided with a first guide wall and a second guide wall, the first guide wall and the second guide wall are respectively provided on opposite sides of the back of the first air duct structure; the guide groove is formed between the first guide wall and the second guide wall.

[0010] The above-mentioned technical solution has the following advantages or beneficial effects: by cooperating with the first guide wall and the second guide wall, a guide groove can be formed on the back of the first air duct structure. The foaming material falling into the guide groove is first confined between the first guide wall and the second guide wall to flow, and then flows from the area between the top of the first guide wall and the second guide wall toward the top area inside the box, and from the area between the bottom of the first guide wall and the second guide wall toward the bottom area inside the box.

[0011] In some embodiments of this application, one of the guide plates is connected to the top end of the first guide wall, and the other guide plate is connected to the top end of the second guide wall.

[0012] The above technical solution has the following advantages or beneficial effects: by connecting the two guide plates to the first guide wall and the second guide wall respectively, the width of the guide channel can be consistent with the width of the guide groove, so that the foaming material in the guide groove can smoothly enter the guide channel and reduce the resistance of foaming flow.

[0013] In some embodiments of this application, a first assembly groove is provided on the side of the top of the first guide wall facing the second guide wall, and the bottom end of one of the guide plates is installed in the first assembly groove; a second assembly groove is provided on the side of the top of the second guide wall facing the first guide wall, and the bottom end of another guide plate is installed in the second assembly groove.

[0014] The above-mentioned technical solution has the following advantages or beneficial effects: by setting a first assembly groove on the inner side wall of the first guide wall, an installation space can be provided for the bottom end of a guide plate, which is conducive to keeping the inner side wall of the guide plate flush with the inner side wall of the first guide wall; by setting a second assembly groove on the inner side wall of the second guide wall, an installation space can be provided for the bottom end of another guide plate, which is conducive to keeping the inner side wall of the guide plate flush with the inner side wall of the second guide wall, thereby making the width of the guide channel consistent with the width of the guide groove.

[0015] In some embodiments of this application, the foaming cavity includes a top cavity, which is formed between the top sidewall of the inner liner and the top wall of the box body; the distance between the top opening of the guide channel and the top cavity is L0, and the length of the guide channel is L1, then the ratio of L1 to L0 is between 0.25 and 0.3.

[0016] The above technical solution has the following advantages or beneficial effects: By using a ratio of L1 to L0 between 0.25 and 0.3, the flow channel can be made neither too long nor too short. An excessively long flow channel increases the flow resistance of the foaming material, thus affecting its flow guiding effect. An excessively short flow channel results in poor flow of the foaming material towards the top area of ​​the box, and the filling speed in the top area of ​​the box will not be significantly accelerated.

[0017] In some embodiments of this application, the foaming cavity includes a left cavity and a right cavity. The left cavity is formed between the left side wall of the inner chamber and the left side wall of the outer chamber, and the right cavity is formed between the right side wall of the inner chamber and the right side wall of the outer chamber. The distance between the left cavity and the right cavity is H0, and the width of the guide groove is H1. Then the ratio of H1 to H0 is between 0.14 and 0.17.

[0018] The above technical solution has the following advantages or beneficial effects: by setting the ratio of H1 to H0 between 0.14 and 0.17, the width of the guide channel can be neither too wide nor too narrow. If the guide channel is too wide, the foaming material will easily flow and diffuse to both sides, affecting the guiding effect of the guide channel and the guide channel; if the guide channel is too narrow, the resistance to the flow of the foaming material will easily increase, affecting the guiding and foaming efficiency.

[0019] In some embodiments of this application, the bottom end of the first guide wall is provided with a first bend, which extends from the bottom end of the first guide wall toward a direction close to the second guide wall; the bottom end of the second guide wall is provided with a second bend, which extends from the bottom end of the second guide wall toward a direction close to the first guide wall. An anti-backflow port is formed between the bottom end of the first bend and the bottom end of the second bend, and the bottom opening of the guide groove communicates with the anti-backflow port and communicates with the bottom area of ​​the foaming cavity through the anti-backflow port.

[0020] The above-mentioned technical solution has the following advantages or beneficial effects: by using the anti-backflow port in conjunction with the gradient structure between the first guide wall and the second guide wall, an anti-backflow structure can be formed at the bottom of the first air duct structure. When the foaming material in the guide groove flows towards the bottom area of ​​the foaming cavity through the bottom opening of the guide groove, the foaming material can smoothly flow to the bottom area of ​​the foaming cavity through the anti-backflow port, and can prevent the foaming material from flowing back into the guide groove through the anti-backflow port.

[0021] In some embodiments of this application, the width of the backflow prevention port is H2, and the width value of H2 is between 55mm and 58mm.

[0022] The above technical solution has the following advantages or beneficial effects: By setting the width of H2 between 55mm and 58mm, the anti-backflow port can be made sufficiently wide, avoiding both excessively wide and narrow anti-backflow ports. This allows the foaming material to flow smoothly through the anti-backflow port to the bottom area of ​​the foaming chamber, while preventing it from flowing back into the guide channel. If the anti-backflow port is too narrow, the foaming material may not be able to flow out of the guide channel in time, colliding with newly injected material in the guide channel and causing overflow at the injection port. If the anti-backflow port is too wide, it will not effectively prevent the foaming material from flowing back.

[0023] In some embodiments of this application, the bottom surface of the housing is provided with an exhaust hole communicating with the foaming cavity, and there are multiple exhaust holes, which are arranged at intervals on the bottom surface of the housing.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: By setting the vent hole on the bottom surface of the box, the gas in the foaming cavity inside the box can be discharged from the bottom area of ​​the box. During the foaming and injection process, the foaming material falling into the guide channel can preferentially flow to the top area of ​​the foaming cavity through the guide channel and guide channel. After the top area of ​​the foaming cavity is filled, the bottom area of ​​the foaming cavity is filled last, and the air in the foaming cavity is gradually discharged from the vent hole. This can reduce the air pressure of the foaming material filling the top of the box and improve the filling quality inside the box.

[0025] In some embodiments of this application, the box liner is provided in multiple ways, and the multiple box liners include a first box liner and a second box liner and a third box liner disposed below the first box liner. The second box liner and the third box liner are arranged left and right at intervals. The first air duct structure is disposed below the first box liner and between the back of the second box liner and the third box liner.

[0026] The above-mentioned technical solution has the following advantages or beneficial effects: by setting the first air duct structure below the first chamber and between the back of the second and third chambers, the guide groove on the back of the first air duct structure can be at a certain distance from the top area and the left and right sides of the chamber, and the guide groove on the back of the first air duct structure can be at a certain distance from the bottom area of ​​the chamber, which facilitates the adjustment and improvement of the foaming filling speed and foaming quality inside the chamber.

[0063] like Figure 4 and Figure 5 As shown, in some embodiments, the housing 1 may include a left panel 11. The left panel 11 may be located on the left side of the housing 1 and serve as the left exterior surface of the housing 1. The left panels 11 may be spaced apart on the left side of the inner liner 2.

[0064] In some embodiments, the housing 1 may include a right panel 12. The right panel 12 may be located on the right side of the housing 1 and serve as the right-side exterior surface of the housing 1. The right panel 12 may be spaced apart on the right side of the inner liner 2.

[0065] In some embodiments, the housing 1 may include a top panel 13. The top panel 13 may be located on the top side of the housing 1 and serve as the top exterior surface of the housing 1. The top panels 13 may be spaced apart on the top side of the inner liner 2.

[0066] In some embodiments, the housing 1 may include a rear panel 14. The rear panel 14 may be located on the back side of the housing 1 and serve as the rear exterior surface of the housing 1. The rear panels 14 may be spaced apart on the back side of the inner liner 2.

[0067] In some embodiments, the housing 1 may include a bottom panel 15. The bottom panel 15 may be located at the bottom of the housing 1 and serve as the bottom exterior surface of the housing 1. The bottom panels 15 may be spaced apart on the bottom side of the inner liner 2.

[0069] like Figure 4 and Figure 5 As shown, in some embodiments, a foaming cavity 4 is formed between the exterior of the liner 2 and the interior of the housing 1. The foaming cavity 4 is used to fill the foaming material, thereby forming a foam layer, which can achieve the heat insulation and heat preservation performance of each refrigeration compartment 10. For example, the foaming cavity 4 can be partially formed in the area between the rear wall of the liner 2 and the rear panel 14, the left side wall of the liner 2 and the left panel 11, the right side wall of the liner 2 and the right panel 12, the top side wall of the liner 2 and the top panel 13, and the bottom side wall of the liner 2 and the bottom panel 15. In addition, the foaming cavity 4 can be partially formed in the interval area between adjacent liner 2.

[0070] Figure 6 yes Figure 5 A magnified view of the local structure.

[0071] like Figure 5 and Figure 6 As shown, in some embodiments, the refrigeration equipment may include a first air duct structure 5, which is disposed in the foaming cavity 4. The first air duct structure 5 can be used to supply air to the inside of the housing liner 2 or to return air from the inside of the housing liner 2. A guide groove 51 may be provided on the back side of the first air duct structure 5. The guide groove 51 is used to receive the injected foaming material, and the landing point of the foaming material is located inside the guide groove 51. The top end of the guide groove 51 is open and faces the top of the housing 1. The bottom end of the guide groove 51 is open and faces the bottom of the housing 1.

[0072] During the foaming material injection process, the housing 1 can be placed flat on the operating table, with the rear panel 14 facing upwards. The foaming machine can extend into the housing 1 through the injection pipe. Since the foaming material's landing point is located within the guide channel 51, the injected foaming material can fall into the guide channel 51. The foaming material falling into the guide channel 51 can move upwards along the guide channel 51, moving through the top opening of the guide channel 51 towards the top area or the sides of the foaming cavity 4, thus preferentially filling the top area of ​​the foaming cavity 4. The foaming material falling into the guide channel 51 can also move downwards along the guide channel 51, moving through the bottom opening of the guide channel 51 towards the bottom area or the sides of the foaming cavity 4.

[0073] In some embodiments, the first air duct structure 5 is spaced from the top region of the foaming cavity 4, such that the top opening of the guide channel 51 is spaced from the top region of the foaming cavity 4, thereby allowing the foaming material falling into the guide channel 51 to flow to the top region of the foaming cavity 4 through the top opening of the guide channel 51, and to move to the side regions of the foaming cavity 4 through the top opening of the guide channel 51.

[0074] like Figure 4 and Figure 5 As shown, in some embodiments, the bottom of the housing 1 may be provided with an injection hole 151, which is located on the bottom plate 15. The injection hole 151 may be located below the first air duct structure 5. The injection hole 151 may be arranged opposite to the guide channel 51. The injection pipe of the foaming machine may extend through the injection hole 151 into the interior of the housing 1, so that the outlet of the injection pipe is located at the guide channel 51, allowing the foaming material sprayed from the injection pipe to fall into the guide channel 51 and preferentially convey the foaming material to the top area of ​​the housing 1 along the guide channel 51.

[0075] like Figure 5 and Figure 6 As shown, in some embodiments, the refrigeration device may include a guide plate 6, which may be disposed between the top region of the first air duct structure 5 and the foaming cavity 4. The guide plate 6 may be disposed on the upper side of the top of the first air duct structure 5. The guide plate 6 may extend upward from the top of the first air duct structure 5. Two guide plates 6 may be provided, and the two guide plates 6 are disposed on opposite sides of the top opening of the guide channel 51. A guide channel 60 is formed between the two guide plates 6, one end of the guide channel 60 is connected to the top opening of the guide channel 51, and the other end of the guide channel 60 extends toward the top region of the foaming cavity 4. Thus, when the foaming material is injected into the guide channel 51, it can flow into the guide channel 60 through the top opening of the guide channel 51 and flow along the guide channel 60 toward the top area of ​​the foaming cavity 4, thereby increasing the foaming filling speed of the top area inside the box 1, allowing the top area inside the box 1 to be filled first, improving the filling quality of the top of the box 1, and thus improving the overall filling quality inside the box 1.

[0076] Figure 7 yes Figure 6 A schematic diagram of the structure of the first air duct component 5.

[0077] like Figure 6 and Figure 7As shown, in some embodiments, the back side of the first air duct structure 5 may be provided with a first guide wall 52 and a second guide wall 53. The first guide wall 52 and the second guide wall 53 are respectively provided on opposite sides of the back of the first air duct structure 5, and a guide groove 51 is formed between the first guide wall 52 and the second guide wall 53. The first guide wall 52 and the second guide wall 53 may be arranged to extend along the height direction of the housing 1. The first guide wall 52 and the second guide wall 53 may abut against the rear panel 14. Through the cooperation of the first guide wall 52 and the second guide wall 53, a guide groove 51 can be formed on the back of the first air duct structure 5, and the foaming material falling into the guide groove 51 is first confined between the first guide wall 52 and the second guide wall 53 to flow, and then flows from the area between the top of the first guide wall 52 and the second guide wall 53 toward the top area inside the housing 1, and from the area between the bottom of the first guide wall 52 and the second guide wall 53 toward the bottom area inside the housing 1.

[0078] In some embodiments, the first guide wall 52 may be disposed on one side edge of the back of the first air duct structure 5. The second guide wall 53 may be disposed on the other side edge of the back of the first air duct structure 5. The first guide wall 52 and the second guide wall 53 may be arranged in parallel with each other. By disposing the first guide wall 52 and the second guide wall 53 on both sides of the back of the first air duct structure 5, the space on the back of the first air duct structure 5 can be fully utilized to form a guide groove 51.

[0079] Figure 8 yes Figure 7 A breakdown diagram.

[0080] like Figure 7 and Figure 8 As shown, in some embodiments, one guide plate 6 can be connected to the top end of the first guide wall 52 and can extend upward from the top end of the first guide wall 52. Another guide plate 6 can be connected to the top end of the second guide wall 53 and can extend upward from the top end of the second guide wall 53. By connecting the two guide plates 6 to the first guide wall 52 and the second guide wall 53 respectively, the width of the guide channel 60 can be kept consistent with the width of the guide groove 51, allowing the foaming material in the guide groove 51 to smoothly enter the guide channel 60, reducing the resistance to foaming flow.

[0081] like Figure 7 and Figure 8As shown, in some embodiments, a first mounting groove 521 may be provided on the top side of the first guide wall 52 facing the second guide wall 53, and the bottom end of a guide plate 6 is installed in the first mounting groove 521. For example, when the bottom end of a guide plate 6 is installed in the first mounting groove 521, the side wall of the guide plate 6 can be arranged flush with the inner side wall of the first guide wall 52. By providing the first mounting groove 521 on the inner side wall of the first guide wall 52, installation space can be provided for the bottom end of the guide plate 6, which is beneficial to keeping the inner side wall of the guide plate 6 flush with the inner side wall of the first guide wall 52, thereby ensuring that the width of the guide channel 60 is consistent with the width of the guide groove 51.

[0082] Figure 9 yes Figure 8 A partial structural diagram from another perspective.

[0083] like Figure 8 and Figure 9 As shown, in some embodiments, a second mounting groove 531 may be provided on the side of the top of the second guide wall 53 facing the first guide wall 52, and the bottom end of the other guide plate 6 is installed in the second mounting groove 531. For example, when the bottom end of the other guide plate 6 is installed in the second mounting groove 531, the side wall of the guide plate 6 can be arranged flush with the inner side wall of the second guide wall 53. By providing the second mounting groove 531 on the inner side wall of the second guide wall 53, installation space can be provided for the bottom end of the other guide plate 6, which is beneficial to keep the inner side wall of the guide plate 6 flush with the inner side wall of the second guide wall 53, thereby making the width of the guide channel 60 consistent with the width of the guide groove 51.

[0084] In some embodiments, the bottom ends of the two guide plates 6 can be fixed to the inner sidewalls of the first guide wall 52 and the second guide wall 53 respectively by means of adhesive.

[0085] In some embodiments, the two guide vanes 6 may be made of cardboard. It should be noted that in other embodiments, the two guide vanes 6 may also be made of other materials. The two guide vanes 6 may also be integrally formed on the top of the first guide wall 52 and the second guide wall 53, that is, the two guide vanes 6 may be integrally formed on the top of the first air duct structure 5.

[0086] Figure 10 yes Figure 7 The front view. Figure 11 yes Figure 3 The front view.

[0087] like Figure 10 and Figure 11As shown, in some embodiments, the foaming cavity 4 may include a top cavity 41, which is formed between the top side wall of the inner chamber 2 and the top wall of the box body 1, i.e., the top cavity 41 may be formed between the top side wall of the inner chamber 2 and the top box plate 13. The distance between the top opening of the guide channel 51 and the top cavity 41 is L0, and the length of the guide channel 60 is L1, then the ratio of L1 to L0 is greater than or equal to 0.25. By ensuring that the ratio of L1 to L0 is greater than or equal to 0.25, the guide plate 6 has sufficient length, i.e., the guide channel 60 between the two guide plates 6 has sufficient length, thereby ensuring that the guide channel 60 has sufficient guiding effect, and allowing the foaming material entering the guide channel 51 to flow smoothly through the guide channel 60 to the top area of ​​the box body 1, effectively ensuring the filling speed and filling quality of the top area inside the box body 1. If the ratio of L1 to L0 is less than 0.25, the flow channel 60 will be too short, resulting in poor flow of the foam material toward the top area inside the box 1, and the filling speed of the top area inside the box 1 will not be significantly accelerated.

[0088] In some embodiments, the ratio of L1 to L0 is less than or equal to 0.3. By ensuring that the ratio of L1 to L0 is less than or equal to 0.3, the guide plate 6 is not too long, that is, the flow channel 60 between the two guide plates 6 is not too long. Since the foamed material has a certain viscosity, an excessively long flow channel 60 will increase the flow resistance of the foamed material, thereby affecting the flow guiding effect of the foamed material.

[0089] In some embodiments, the ratio of L1 to L0 is between 0.25 and 0.3. This ratio ensures that the flow channel 60 is neither too long nor too short. An excessively long flow channel 60 increases the flow resistance of the foaming material, thus affecting its guiding effect. An excessively short flow channel 60 results in poor guiding of the foaming material towards the top area of ​​the housing 1, and the filling speed in the top area of ​​the housing 1 does not increase significantly.

[0090] like Figure 10 and Figure 11 As shown, in some embodiments, the foaming cavity 4 may include a left cavity 42 and a right cavity 43. The left cavity 42 may be formed between the left side wall of the inner chamber 2 and the left side wall of the body 1, that is, the left cavity 42 may be formed between the left side wall of the inner chamber 2 and the left box plate 11. The right cavity 43 may be formed between the right side wall of the inner chamber 2 and the right side wall of the body 1. The right cavity 43 may be formed between the right side wall of the inner chamber 2 and the right box plate 12. The distance between the left cavity 42 and the right cavity 43 can be H0, and the width of the guide channel 51 can be H1, then the ratio of H1 to H0 is greater than or equal to 0.14. By having a ratio of H1 to H0 greater than or equal to 0.14, the guide channel 51 can have a sufficient width, avoiding the guide channel 51 being too narrow and increasing the resistance to the flow of the foaming material.

[0091] In some embodiments, the ratio of H1 to H0 is less than or equal to 0.17. By ensuring that the ratio of H1 to H0 is less than or equal to 0.17, the guide channel 51 is prevented from being too wide. If the guide channel 51 is too wide, the foaming material will easily flow and diffuse to both sides, affecting the guiding effect of the guide channel 51 and the guide channel 60.

[0092] In some embodiments, the ratio of H1 to H0 is between 0.14 and 0.17. By setting the ratio of H1 to H0 between 0.14 and 0.17, the width of the guide channel 51 is prevented from being too wide or too narrow. If the guide channel 51 is too wide, the foaming material will easily flow and diffuse to both sides, affecting the guiding effect of the guide channel 51 and the guide channel 60; if the guide channel 51 is too narrow, the resistance to the flow of the foaming material will easily increase, affecting the guiding and foaming efficiency.

[0093] like Figure 6 and Figure 7 As shown, in some embodiments, the bottom end of the first guide wall 52 may be provided with a first bend 54. The first bend 54 may extend from the bottom end of the first guide wall 52 toward a direction close to the second guide wall 53. The bottom end of the second guide wall 53 may be provided with a second bend 55. The second bend 55 may extend from the bottom end of the second guide wall 53 toward a direction close to the first guide wall 52. The first bend 54 and the second bend 55 are arranged facing each other and extending toward the bottom of the housing 1. There may be a backflow prevention port 56 between the bottom end of the first bend 54 and the bottom end of the second bend 55. The bottom opening of the guide groove 51 communicates with the backflow prevention port 56 and communicates with the bottom area of ​​the foaming chamber 4 through the backflow prevention port 56. By using the anti-backflow port 56 in conjunction with the gradient structure between the first guide wall 52 and the second guide wall 53, an anti-backflow structure can be formed at the bottom of the first air duct structure 5. When the foaming material in the guide channel 51 flows towards the bottom area of ​​the foaming cavity 4 through the bottom opening of the guide channel 51, the foaming material can smoothly flow to the bottom area of ​​the foaming cavity 4 through the anti-backflow port 56, and can prevent the foaming material from flowing back into the guide channel 51 through the anti-backflow port 56.

[0094] like Figure 10 and Figure 11 As shown, in some embodiments, the width of the anti-backflow port 56 is H2, where the width of H2 is greater than or equal to 55mm. The width of H2 being greater than or equal to 55mm ensures that the anti-backflow port 56 has sufficient width, allowing the foaming material to flow smoothly through the anti-backflow port 56 to the bottom area of ​​the foaming chamber 4, guaranteeing the flow rate and foaming efficiency of the foaming material, and preventing the anti-backflow port 56 from being too narrow. If the anti-backflow port 56 is too narrow, the foaming material may not be able to flow out of the guide channel 51 in time, colliding with the newly injected material in the guide channel 51, resulting in overflow at the injection port.

[0095] In some embodiments, the width of H2 is less than or equal to 58 mm. By ensuring that the width of H2 is less than or equal to 58 mm, the backflow prevention port 56 can be prevented from being too wide, otherwise it will not be able to prevent the foam material from flowing back.

[0096] In some embodiments, the width of H2 is between 55mm and 58mm. Setting the width of H2 between 55mm and 58mm ensures that the anti-backflow port 56 has sufficient width, preventing it from being too wide or too narrow. This allows the foaming material to flow smoothly through the anti-backflow port 56 to the bottom area of ​​the foaming chamber 4, while preventing it from flowing back into the guide channel 51. If the anti-backflow port 56 is too narrow, the foaming material may not flow out of the guide channel 51 in time, colliding with newly injected material in the guide channel 51 and causing overflow at the injection port. If the anti-backflow port 56 is too wide, it will not effectively prevent the foaming material from flowing back.

[0097] like Figure 4 , Figure 5 and Figure 11 As shown, in some embodiments, the bottom surface of the housing 1 may be provided with vent holes 152 communicating with the foaming cavity 4, and the vent holes 152 may be provided on the bottom plate 15. Multiple vent holes 152 may be provided, and the multiple vent holes 152 are arranged at intervals on the bottom surface of the housing 1. By providing vent holes 152 on the bottom surface of the housing 1, the gas inside the foaming cavity 4 of the housing 1 can be discharged from the bottom area of ​​the housing 1. During the foaming and injection process, the foaming material falling into the guide channel 51 can preferentially flow through the guide channel 51 and the guide channel 60 to the top area of ​​the foaming cavity 4. After the top area of ​​the foaming cavity 4 is filled, the bottom area of ​​the foaming cavity 4 is filled last, and the air inside the foaming cavity 4 is gradually discharged from the vent holes 152. This can reduce the air pressure of the foaming material filling the top of the housing 1 and improve the filling quality inside the housing 1.

[0098] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, the multiple inner chambers 2 within the housing 1 may include a first inner chamber 2a and a second inner chamber 2b and a third inner chamber 2c located below the first inner chamber 2a. The second inner chamber 2b and the third inner chamber 2c are arranged at a left-right interval. A first air duct structure 5 may be located below the first inner chamber 2a, and the first air duct structure 5 may be located in the area between the backs of the second inner chamber 2b and the third inner chamber 2c. In this way, the guide groove 51 on the back of the first air duct structure 5 can be at a certain distance from the top area and the left and right side areas inside the housing 1, which facilitates the adjustment and improvement of the foaming filling speed and foaming quality inside the housing 1.

[0099] It should be noted that in some other embodiments, the plurality of inner chambers 2 within the housing 1 may also include only a first inner chamber 2a and a second inner chamber 2b located below the first inner chamber 2a. The first air duct structure 5 may be located below the first inner chamber 2a and between the second inner chamber 2b.

[0100] In some embodiments, the first air duct structure 5 may be disposed in the top region between the back of the second box liner 2b and the third box liner 2c, so that the guide groove 51 on the back of the first air duct structure 5 is at a certain distance from the top region inside the box 1, and the guide groove 51 on the back of the first air duct structure 5 is at a certain distance from the bottom region inside the box 1.

[0101] like Figure 5 , Figure 6 and Figure 11 As shown, in some embodiments, a notch 57 may be formed between the first bending portion 54, the second bending portion 55, and the bottom surface of the first air duct structure 5. The notch 57 communicates with the foaming cavity 4 between the second liner 2b and the third liner 2c. The foaming material in the guide channel 51 can flow into the foaming cavity 4 between the second liner 2b and the third liner 2c through the notch 57, thereby improving the filling speed and filling quality of the foaming cavity 4 between the second liner 2b and the third liner 2c.

[0102] like Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, a support surface 58 may be provided on the top region of the back of the first air duct structure 5. The top opening of the guide groove 51 is arranged facing the support surface 58. The bottom end of the guide plate 6 may be supported on the support surface 58, thereby improving the structural stability of the guide plate 6.

[0103] In some embodiments, an inclined surface 59 may be provided between the bottom surface of the guide channel 51 and the supporting surface 58. During the foaming process of the housing 1, the back of the housing 1 is arranged facing upwards, and the height of the supporting surface 58 is higher than the bottom surface of the guide channel 51. The inclined surface 59 may be arranged inclined upwards from the bottom surface of the guide channel 51 toward the supporting surface 58. The inclined surface 59 allows some of the foaming material falling into the guide channel 51 to move toward the bottom opening of the guide channel 51, and then flow into the bottom of the housing 1 and the foaming cavity 4 between the second chamber 2b and the third chamber 2c.

[0104] like Figure 6 , Figure 8 and Figure 11As shown, in some embodiments, the first air duct structure 5 can be an air supply structure. The air supply structure includes an air supply duct 50, one end of which connects to the cooling compartment 10 inside the second liner 2b, and the other end of which connects to the cooling compartment 10 inside the third liner 2c. Thus, the second liner 2b can supply cold air to the third liner 2c via the air supply duct 50, or the third liner 2c can supply cold air to the second liner 2b via the air supply duct 50.

[0105] It should be noted that in other embodiments, the first air duct structure 5 can also be a return air structure. The return air structure is provided with a return air duct 70, one end of which is connected to the refrigeration chamber 10 inside the second liner 2b, and the other end of which is connected to the refrigeration chamber 10 inside the third liner 2c.

[0106] Figure 12 yes Figure 3 A schematic diagram of the structure of the second air duct component 7.

[0107] like Figure 6 , Figure 8 and Figure 11 As shown, in some embodiments, the refrigeration equipment may include a second air duct structure 7. The second air duct structure 7 may be a return air structure. A return air duct 70 is provided within the second air duct structure 7, one end of which connects to the refrigeration chamber 10 within the second liner 2b, and the other end of which connects to the refrigeration chamber 10 within the third liner 2c. Thus, the first air duct structure 5 can cooperate with the second air duct structure 7 to form a cooling air circulation within the second liner 2b and the third liner 2c.

[0108] It should be noted that in other embodiments, the second air duct structure 7 can also be an air supply structure.
