[0008] Fasteners are used to securely connect the air duct panel and the inner wall of the receiving cavity.

[0009] In the refrigeration equipment proposed in this application embodiment, since the fasteners fix and connect the air duct panel and the inner wall of the receiving cavity, the air duct module is installed by connecting the air duct panel and the inner wall of the receiving cavity. Since the air duct rear cover is disposed between the inner wall of the receiving cavity and the air duct panel, the connection force between the air duct panel and the air duct rear cover, and the connection force between the air duct panel and the inner wall of the receiving cavity are both in the same direction. Therefore, the connection force between the air duct panel and the inner wall of the receiving cavity will not pull the air duct panel away from the air duct rear cover, thereby reducing the gap between the air duct panel and the air duct rear cover.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that all directional indications in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0037] Refrigeration equipment can be used to refrigerate items. The refrigeration equipment includes an air duct module, which has an air outlet and an air return outlet. Hot air inside the refrigeration equipment enters the air duct module through the air return outlet, is cooled, and then flows back into the cavity through the air outlet to achieve cooling.

[0038] The air duct module includes an air duct panel and an air duct rear cover. In related technologies, the air duct rear cover is positioned between the air duct panel and the inner wall of the refrigeration equipment. The air duct rear cover is first connected to the air duct panel as a single unit, and then connected to the inner wall to achieve the installation of the air duct module. However, when the air duct rear cover is connected to the inner wall, it will be subjected to two connecting forces in different directions. The connecting force between the air duct rear cover and the inner wall will, to some extent, pull the air duct rear cover away from the air duct panel, resulting in a gap between the air duct panel and the air duct rear cover.

[0039] In order to solve the problems existing in the related technologies, this application provides a refrigeration device that can reduce the gap between the air duct panel and the air duct rear cover.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Please see Figures 1-3 This application provides a refrigeration device 10, which can reduce the gap between the air duct panel 110 and the air duct rear cover 120.

[0042] The refrigeration equipment 10 can be a refrigerator or a freezer. Specifically, the freezer can be a horizontal freezer or a vertical freezer. In this embodiment, for ease of description, a horizontal freezer is used as an example for illustrating the refrigeration equipment 10. The same principle applies when the refrigeration equipment 10 is other equipment.

[0043] Please see Figures 2-5 In this embodiment, the refrigeration device 10 includes a cabinet 200, an air duct module 100, and fasteners 300. The cabinet 200 has a receiving cavity 210, and the air duct module 100 is disposed within the receiving cavity 210. The air duct module 100 includes an air duct panel 110, an air duct rear cover 120, and a guide component 150. The air duct rear cover 120 is disposed between the inner wall of the receiving cavity 210 and the air duct panel 110. The air duct panel 110 and the air duct rear cover 120 are connected to form an installation cavity 130, and the guide component 150 is installed within the installation cavity 130. The fasteners 300 are fixedly connected to the air duct panel 110 and the inner wall of the receiving cavity 210.

[0044] The horizontal freezer is mainly used for refrigerating items. The cabinet 200 is the main structure of the entire horizontal freezer. It can provide the installation base for the air duct module 100, compressor 160, evaporator 170 and other structures, and can also protect the aforementioned electronic components.

[0045] Please refer to Figure 1 and Figure 2The cabinet 200 includes a main body 220 and a door 230 connected to the main body 220. The door 230 covers the opening 221 of the main body 220. The receiving cavity 210 is set inside the main body 220. The items to be refrigerated are placed inside the receiving cavity 210 and frozen by the cold air blown out by the air duct module 100.

[0046] The cabinet body 200 is roughly a cuboid. For ease of description, we define the height direction (Z), width direction (X), and thickness direction (Y). In the usage state of a horizontal freezer, the vertical direction is the height direction (Z), and the projection of the main body 220 in the vertical direction is a rectangle. The direction of the longer side is the width direction (X), and the direction of the shorter side is the thickness direction (Y).

[0047] Since the thickness of the air duct module 100 is relatively small compared to its width, and the width of the air duct module 100 is basically equal to the thickness of the cabinet 200, the air duct module 100 can be installed on one side of the cabinet 200 in the width direction X, so that the air blown out from the air duct module 100 can cover the side formed by the length and width directions X as much as possible, thereby allowing the air blown out from the air duct module 100 to cover the entire interior of the cabinet 200, and improving the uniformity of freezing as much as possible.

[0048] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, the direction closer to the loading / unloading opening 221 is up, and the direction farther from the opening 221 is down. In the width direction X, the two directions are left and right, with the installation position of the air duct module 100 being right, and the opposite side being left. In the thickness direction Y, the connection point between the door body 230 and the main body 220 is back, and the opposite side is front.

[0049] Please see Figure 3 and Figure 4 The air duct module 100 enables airflow within the refrigeration unit 10 (horizontal freezer), allowing the cooled air to be blown onto the frozen items for freezing. A fixed cavity 140 for mounting the evaporator 170 is formed between the air duct panel 110 and the inner wall of the receiving cavity 210. The air duct panel 110 has an air outlet 111 and an air return vent 112, and the air duct rear cover plate 120 has an air inlet 121. Under the action of the guide member 150, air from the receiving cavity 210 enters the fixed cavity 140 through the air return vent 112, is cooled by the evaporator 170, flows through the air inlet 121 to the mounting cavity 130, and then is blown into the receiving cavity 210 through the air outlet 111. In other words, the evaporator 170 is located between the return air inlet 112 and the air inlet 121, and it cools the air during the air circulation process, so that the air blown out from the air outlet 111 is always cold air, so as to achieve the cooling of the housing 210.

[0050] The flow guide 150 can be a fan, specifically a centrifugal fan, an axial fan, or a cross-flow fan.

[0051] Please see Figure 4 and Figure 5 The air duct panel 110 and the air duct rear cover plate 120 can be first positioned by snap-fit ​​connection to ensure the accurate position of the formed installation cavity 130, and then fixed by bolts to ensure the fixing effect between the air duct panel 110 and the air duct rear cover plate 120, so that the drainage component 150 is installed stably.

[0052] Since the air duct module 100 is installed on the right, it can be understood that the "inner wall of the receiving cavity 210" mentioned above refers to the inner wall on the right side of the receiving cavity 210.

[0053] Since the fastener 300 fixes the air duct panel 110 and the inner wall of the receiving cavity 210, the air duct module 100 is installed through the connection between the air duct panel 110 and the inner wall of the receiving cavity 210. Because the air duct rear cover plate 120 is located between the inner wall of the receiving cavity 210 and the air duct panel 110, the connection force between the air duct panel 110 and the inner wall of the receiving cavity 210 is on the side of the air duct panel 110 closest to the inner wall. The connection force between them is also on the side of the air duct panel 110 near the inner wall. That is, the connection force between the air duct panel 110 and the air duct rear cover plate 120 and the connection force between the air duct panel 110 and the inner wall of the receiving cavity 210 are both in the same direction. Therefore, the connection force between the air duct panel 110 and the inner wall of the receiving cavity 210 will not pull the air duct panel 110 away from the air duct rear cover plate 120, thereby reducing the gap between the air duct panel 110 and the air duct rear cover plate 120.

[0054] Please see Figures 4-6 In some embodiments, the duct panel 110 is provided with a first connection hole 114, the cabinet 200 is provided with a second connection hole 240, and the fastener 300 passes through the first connection hole 114 and the second connection hole 240.

[0055] Fastener 300 passes through the first connecting hole 114 and the second connecting hole 240, thereby connecting the air duct panel 110 and the inner wall of the receiving cavity 210. Specifically, the first connecting hole 114 and the second connecting hole 240 can be coaxially arranged threaded holes, and the fastener 300 can be a bolt. The fastener 300 is threadedly connected to the first connecting hole 114 and the second connecting hole 240, thereby connecting the air duct panel 110 and the inner wall.

[0056] In some embodiments, the rear cover plate 120 of the air duct is provided with a clearance opening 122, and the fastener 300 passes through the clearance opening 122.

[0057] It is understandable that, since the duct rear cover plate 120 is located between the inner wall of the receiving cavity 210 and the duct panel 110, when the fastener 300 is directly connected to the inner wall of the duct panel 110 and the receiving cavity 210, it needs to pass through the duct rear cover plate 120. Therefore, the duct rear cover plate 120 is provided with a clearance opening 122. The first connecting hole 114, the clearance opening 122 and the second connecting hole 240 can be coaxially arranged, so that the fastener 300 can be sequentially inserted into the first connecting hole 114, the clearance opening 122 and the second connecting hole 240 to connect the duct panel 110 and the inner wall of the receiving cavity 210.

[0058] Specifically, the clearance opening 122 can be a screw hole, in which case the fastener 300 can be threadedly connected to the screw hole on the air duct rear cover plate 120, and can be inserted into the air duct rear cover plate 120 and connected to the second connecting hole 240; or, the clearance opening 122 can also be a through hole, and the fastener 300 can directly pass through the clearance opening 122, without any restriction.

[0059] Please see Figure 5 In some embodiments, the duct panel 110 is provided with a mounting groove 113, a first connecting hole 114 is provided on the side 113b of the mounting groove 113 near the inner wall, and a portion of the fastener 300 is located in the mounting groove 113.

[0060] Please see Figure 7 and Figure 8 The mounting groove 113 has a bottom surface 113a and a side surface 113b. The first connecting hole 114 is provided on the side surface 113b of the mounting groove 113 near the inner wall, so that the fastener 300 can be easily connected to the inner wall.

[0061] The first connecting hole 114 communicates with the mounting groove 113. A portion of the fastener 300 passes through the first connecting hole 114, the clearance opening 122, and the second connecting hole 240, while the other portion is located within the mounting groove 113. This minimizes the protrusion of the fastener 300 from the outer surface of the duct panel 110, keeping the outer surface of the duct panel 110 clean. When installing the fastener 300, first place the fastener 300 into the mounting groove 113, and then sequentially pass it through the first connecting hole 114, the clearance opening 122, and the second connecting hole 240.

[0062] Please see Figure 5 In some embodiments, the duct panel 110 has a mounting portion 115 protruding into the mounting cavity 130, and a mounting groove 113 is disposed in the mounting portion 115.

[0063] The mounting groove 113 is provided on the outer surface of the air duct panel 110, and the mounting cavity 130 is provided inside the air duct panel 110. The mounting part 115 protruding into the mounting cavity 130 means that the mounting part 115 protrudes towards the center of the mounting cavity 130. For example, if the mounting part 115 is located at the top of the air duct panel 110, the mounting cavity 130 protrudes downward; if the mounting part 115 is located at the left side of the air duct panel 110, the mounting cavity 130 protrudes to the right, and so on.

[0064] Because the thickness of the duct panel 110 is limited, creating a mounting groove 113 on the duct panel 110 would thin out a local area of ​​the duct panel 110, potentially affecting its structural strength. Furthermore, the mounting groove 113 needs to have sufficient depth to adequately conceal the fastener 300. Therefore, the duct panel 110 has a mounting portion 115 protruding into the mounting cavity 130, and a mounting groove 113 is created in the mounting portion 115. The mounting groove 113 is located on the side of the mounting portion 115 facing away from the mounting cavity 130, thus maximizing the thickness of the duct panel 110 while ensuring the mounting groove 113 has sufficient depth.

[0065] Specifically, the air duct panel 110 includes a main panel 118a, a top panel 118c, and two side panels 118b. The two side panels 118b are respectively disposed on both sides of the main panel 118a. The top panel 118c is disposed on the upper part of the main panel 118a and extends into the inner wall. The main panel 118a, the top panel 118c, and the two side panels 118b together form an air duct with the inner wall of the receiving cavity 210. The mounting part 115 can be disposed on the top panel 118c and is integrally disposed with the top panel 118c, that is, a part of the top panel 118c protrudes downward to form the mounting part 115.

[0066] Please see Figure 5 In some embodiments, the mounting slot 113 is located on top of the air duct panel 110.

[0067] The top of the air duct panel 110 is the outer surface of the air duct panel 110 near the pick-and-place port 221. Since the air duct module 100 is first placed into the receiving cavity 210 through the pick-and-place port 221 when installing the air duct module 100, and then the air duct panel 110 and the inner wall of the receiving cavity 210 are connected by fasteners 300, and the entire connection process is carried out by the operator using tools to reach into the receiving cavity 210 through the pick-and-place port 221, the mounting groove 113 is set near the pick-and-place port 221, which makes it convenient for the operator to install the air duct module 100.

[0068] Since the mounting groove 113 is located at the top of the air duct panel 110, the fastener 300 can be hidden in the height direction Z. Of course, in other embodiments, the mounting groove 113 can also be located on the side of the air duct panel 110. In this case, the fastener 300 needs to be hidden in the thickness direction Y. There is no limitation on this.

[0069] Please see Figure 5 In some embodiments, the air duct module 100 also includes a decorative cover plate 190, which is detachably connected to the air duct panel 110 and covers the mounting groove 113.

[0070] Although the mounting groove 113 can hide the fastener 300 in the height direction Z so that the fastener 300 does not protrude from the outer surface of the air duct panel 110, the fastener 300 is still exposed, resulting in an untidy appearance of the air duct panel 110. Therefore, the decorative cover 190 is detachably connected to the air duct panel 110 and covers the mounting groove 113. That is, the decorative cover 190 is set opposite to the bottom surface 113a of the mounting groove 113, thereby covering the fastener 300 in the mounting groove 113 and making the appearance of the air duct panel 110 neater.

[0071] Since the decorative cover 190 is detachably connected to the air duct panel 110, when installing the air duct panel 110, the decorative cover 190 is removed, and the fastener 300 is operated in the mounting groove 113 to connect the air duct panel 110 and the inner wall of the receiving cavity 210. After the air duct panel 110 is installed, the decorative cover 190 is then installed.

[0072] Specifically, the decorative cover 190 can be flush with the outer surface of the air duct panel 110 to further improve the appearance of the air duct panel 110.

[0073] Please see Figure 7 and Figure 8 In some embodiments, the decorative cover plate 190 is provided with a first snap-fit ​​member 191, and the mounting groove 113 is provided with a second snap-fit ​​member 116. The first snap-fit ​​member 191 snaps into the second snap-fit ​​member 116 to connect the decorative cover plate 190 and the mounting groove 113.

[0074] To facilitate the installation and removal of the decorative cover 190, the decorative cover 190 and the air duct panel 110 can be snapped together, allowing operators to manually install and remove the decorative cover 190. Since the decorative cover 190 is positioned opposite the bottom surface 113a of the mounting groove 113, a second snap-fit ​​member 116 is provided on the bottom surface 113a of the mounting groove 113 for easy snap-fit ​​connection.

[0075] Specifically, the first snap-fit ​​component 191 can be a snap-fit ​​claw, and the second snap-fit ​​component 116 can be a snap-fit ​​hole. The snap-fit ​​claw snaps into the snap-fit ​​hole, thus connecting the decorative cover 190 and the air duct panel 110. Of course, the first snap-fit ​​component 191 can also be a snap-fit ​​hole, and the second snap-fit ​​component 116 can be a snap-fit ​​claw; there is no limitation on this.

[0076] Please see Figure 3 and Figure 9 In some embodiments, the duct panel 110 includes a first shell section 110a, a second shell section 110b, and a third shell section 110c connected in sequence. The first shell section 110a and the duct rear cover plate 120 form a mounting cavity 130, and a mounting groove 113 is disposed in the first shell section 110a. The second shell section 110b and the inner wall of the receiving cavity 210 form a fixing cavity 140 for mounting the evaporator 170.

[0077] The first shell section 110a is located above the second shell section 110b, and the second shell section 110b is located above the third shell section 110c. The first shell section 110a and the rear shell form an installation cavity 130 for accommodating the air guide 150. The air outlet 111 is located in the first shell section 110a and communicates with the installation cavity 130. The return air outlet 112 is located in the third shell section 110c and communicates with the fixing cavity 140.

[0078] It should be noted that the evaporator 170 is fixed within the fixed cavity 140 formed by the second shell section 110b, the third shell section 110c, and the cabinet 200, which facilitates the assembly of the air duct module 100 and the evaporator 170. During assembly, the air duct module 100 is first assembled into a whole, the evaporator 170 is assembled in the designated position of the receiving cavity 210, and then the entire air duct module 100 is assembled into the receiving cavity 210, so that the second shell section 110b and the third shell section 110c cover the evaporator 170, forming a closed fixed cavity 140 with the main body 220. This allows the air in the receiving cavity 210 to enter the fixed cavity 140 through the return air port 112, be cooled by the evaporator 170, and then flow to the air outlet 111.

[0079] It is understandable that although the connection force between the air duct panel 110 and the air duct rear cover plate 120 and the connection force between the air duct panel 110 and the inner wall of the receiving cavity 210 are both in the same direction, the air duct panel 110 is still subjected to two different connection forces, which may cause the air duct panel 110 to be slightly pulled, resulting in a small gap between the air duct panel 110 and the air duct rear cover plate 120.

[0080] In this embodiment, since the duct rear cover plate 120 is only connected to the first shell section 110a to form the mounting cavity 130, that is, the duct rear cover plate 120 is only partially connected to the duct panel 110, the size of the duct panel 110 is much larger than the size of the duct rear cover plate 120. Therefore, the connection force between the duct panel 110 and the duct rear cover plate 120 is relatively weak. The duct panel 110 and the duct rear cover plate 120 can be regarded as a whole. In other words, the duct rear cover plate 120 can be regarded as one of the components of the duct panel 110. Thus, the connection force between the duct panel 110 and the duct rear cover plate 120 has little impact on the connection force between the duct panel 110 and the inner wall. This can improve the pulling situation of the two connection forces on the duct panel 110 and further reduce the gap between the duct panel 110 and the duct rear cover plate 120.

[0081] Please see Figure 6 In some embodiments, the inner wall of the receiving cavity 210 has a side wall 211 and a mounting wall 213 arranged at an angle, and the air duct panel 110 is mounted on the mounting wall 213 and connected to the side wall 211.

[0082] Mounting wall 213 is located below air duct module 100 and supports air duct module 100. Please refer to [link / reference]. Figure 3 The receiving cavity 210 has a bottom wall 212, and the mounting wall 213 can be higher than the bottom wall 212. When users place items in the receiving cavity 210, they usually start to pile them up from the bottom of the receiving cavity 210, meaning that the bottom of the receiving cavity 210 is the easiest to fill with items. If the air duct module 100 is placed directly at the bottom of the receiving cavity 210, the items can easily block the air vents of the air duct module 100, causing the air in the receiving cavity 210 to be unable to return, which can easily cause the air in the receiving cavity 210 to not circulate, resulting in insufficient cooling capacity in the receiving cavity 210 and affecting the cooling effect.

[0083] In this embodiment, the air duct module 100 is mounted on the mounting wall 213, meaning that the air outlet of the air duct module 100 is at least above the mounting wall 213. The height of the mounting wall 213 is higher than the bottom wall 212 of the receiving cavity 210, ensuring a certain height between them. This allows the air outlet of the air duct module 100 to be at a certain height from the bottom wall 212 when the user is stacking items, preventing the air outlet from being blocked and enabling the air in the receiving cavity 210 to circulate, thus improving the overall cooling effect of the horizontal freezer.

[0084] Please see Figure 3The main body 220 includes an inner liner 222 and an outer shell 223, with a foam layer filling the space between them. A receiving cavity 210 is located inside the inner liner 222, and an electrical cavity 214 for accommodating the compressor 160 is located between the inner liner 222 and the outer shell 223. Since the overall appearance of the cabinet 200 is roughly cuboid, the electrical cavity 214 between the inner liner 222 and the outer shell 223 makes the inner liner 222 not a regular cuboid. This creates a stepped surface above the electrical cavity 214, which can be configured as a mounting wall 213. The return air vent 112 is located at this position, utilizing the existing structure of the horizontal freezer. This eliminates the need for a separate mounting wall 213 higher than the bottom wall 212 within the receiving cavity 210. This improves the problem of air vent blockage in the air duct module 100, reduces the number of components in the horizontal freezer, and reduces the volume occupied by the receiving cavity 210.

[0085] Of course, in other embodiments, the air duct panel 110 may also be installed on the bottom wall 212, and there is no limitation thereto.

[0086] Please see Figure 5 and Figure 6 In some embodiments, one of the duct panel 110 and the mounting wall 213 is provided with a positioning member 117 and the other is provided with a positioning hole 250, with the positioning member 117 being engaged in the positioning hole 250.

[0087] Since the position of the air duct module 100 within the receiving cavity 210 is fixed, the mounting wall 213 not only supports the air duct module 100 but also positions it. Specifically, when installing the air duct module 100, the air duct panel 110 is first positioned on the mounting wall 213. Once the air duct panel 110 is positioned, the entire air duct module 100 is positioned. Then, connecting the air duct panel 110 to the inner wall of the receiving cavity 210 ensures accurate installation of the air duct module 100.

[0088] Since one of the duct panel 110 and the mounting wall 213 is provided with a positioning element 117 and the other with a positioning hole 250, the positioning element 117 can be engaged in the positioning hole 250, thus enabling the duct panel 110 to be positioned on the mounting wall 213. Specifically, the duct panel 110 can be provided with the positioning element 117 and the mounting wall 213 can be provided with the positioning hole 250, or the duct panel 110 can be provided with the positioning hole 250 and the mounting wall 213 can be provided with the positioning element 117; there is no limitation on this.
