Detailed Implementation

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0045] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0046] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" 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 invention according to the specific circumstances.

[0047] Furthermore, in this invention, 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 invention.

[0048] In related technologies, refrigeration equipment suffers from the technical problem of large external dimensions. This application provides a refrigeration device that can at least partially solve the technical problem of large external dimensions in refrigeration equipment.

[0049] The refrigeration equipment can be a refrigerator, freezer, etc., and is not limited in this application. For ease of description, the following description uses a refrigerator as an example of the refrigeration equipment.

[0050] The refrigeration equipment is roughly rectangular. For ease of description, we define the height direction (Z), width direction (X), and thickness direction (Y). In the operating state of the refrigeration equipment, the vertical direction is the height direction (Z), and the projection of the refrigeration equipment 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).

[0051] 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 top surface is up, and the direction further from the top surface is down. In the width direction X, the two directions are left and right. The refrigeration equipment chamber has an opening for loading and unloading, and a door is located at the opening. In the thickness direction Y, the direction closer to the door is front, and the direction further from the door is back.

[0052] This application is described below with reference to the accompanying drawings and specific embodiments:

[0053] like Figures 1 to 6 As shown, the refrigeration equipment 1000 includes a housing 100, an air duct module 200, a terminal module 300, and an air supply module 400. The housing 100 has a receiving cavity 100a. The air duct module 200 is disposed inside the housing 100. The terminal module 300 is installed in the air duct module 200 and is used to electrically connect to the electrical control box 700 of the refrigeration equipment 1000. The air supply module 400 is installed in the air duct module 200 and is electrically connected to the terminal module 300.

[0054] The receiving cavity 100a can be used to store food, ice packs, flowers, and other items that require refrigeration. The air duct module 200 is located inside the cabinet 100, either inside or outside the receiving cavity 100a, for example, between the rear wall of the cabinet and the inner liner; this is not limited in this application. An air outlet duct 210a can be formed within the air duct module 200, connecting to the receiving cavity 100a, through which air is supplied to the receiving cavity 100a to regulate its temperature.

[0055] Terminal module 300 has an input terminal 311 and an output terminal 312. Output terminal 312 is electrically connected to the electrical control box 700 and the air supply module 400. Input terminal 311 and the electrical control box 700 can be electrically connected via wires, and output terminal 312 and the air supply module 400 can also be electrically connected via wires. In some embodiments, input terminal 311 and the electrical control box 700 are electrically connected via a terminal connection line 800.

[0056] Terminal module 300 is fixedly connected to air duct module 200. It can be located inside or outside air duct module 200. Air supply module 400 is located inside air duct module 200, which can promote air circulation within receiving cavity 100a.

[0057] The refrigeration equipment 1000 connects the air supply module 400 to the terminal module 300 via wires or other electrical connections. Then, the terminal module 300 and the electrical control box 700 are connected via the terminal connection line 800, thus achieving electrical connection between the air supply module 400 and the electrical control box 700. This design eliminates the need for a separate wire to the electrical control box 700 for the air supply module 400, which helps to shorten the length of the wires between the air supply module 400 and the heating module 500, saving production costs for the refrigeration equipment 1000. By placing the terminal module 300 on the air duct module 200, the space on the air duct module 200 is utilized, which reduces the space occupied by the terminal module 300. The more reasonable placement of the terminal module 300 helps to reduce the overall size of the refrigeration equipment 1000. In addition, with this design, the terminal module 300 can be pre-installed on the air duct module 200, that is, it is first installed on the air duct module 200, and then the air duct module 200 is assembled on the housing 100. When installing the terminal module 300, since the air duct module 200 is not yet installed on the housing 100, the installation of the terminal module 300 is not limited by the housing 100, which reduces the installation difficulty of the terminal module 300 and improves the assembly efficiency of the various components of the refrigeration equipment 1000.

[0058] In some embodiments, the refrigeration device 1000 further includes a heating module 500, which is installed in the air duct module 200 and electrically connected to the terminal module 300.

[0059] Terminal module 300 has an input terminal 311 and an output terminal 312. Output terminal 312 is electrically connected to the electrical control box 700. Output terminal 312 is also electrically connected to both the air supply module 400 and the heating module 500. Input terminal 311 and the electrical control box 700 can be electrically connected via wires, and output terminal 312 and the heating module 500 can also be electrically connected via wires. Heating module 500 is located within the air duct module 200 and can perform heating and defrosting of components such as the evaporator within the air duct module 200. The refrigeration equipment 1000 connects the heating module 500 to the terminal module 300 via wires or other electrical connections. Then, the terminal module 300 and the electrical control box 700 are connected via the terminal connection line 800, thus achieving electrical connection between the heating module 500 and the electrical control box 700. This design eliminates the need for a separate wire to the electrical control box 700 for the heating module 500, which helps to shorten the length of the wires for the heating module 500 and saves on the production cost of the refrigeration equipment 1000.

[0060] like Figure 4 and Figure 6As shown, in some embodiments, the air duct module 200 includes a first air duct module 210, a second air duct module 220 and a third air duct module 230 arranged sequentially along the height direction of the housing 100. The second air duct module 220 is connected to the first air duct module 210 and the third air duct module 230, and the first air duct module 210 is located above the third air duct module 230. The terminal module 300 is disposed on the second air duct module 220, and the air supply module 400 and / or the heating module 500 are installed in the third air duct module 230.

[0061] The air supply module 400 is installed inside the air duct module 230, the heating module 500 is installed inside the air duct module 230, or both the air supply module 400 and the heating module 500 are installed inside the third air duct module 230. In some embodiments, both the air supply module 400 and the heating module 500 are installed inside the third air duct module 230. The first air duct module 210 has an outlet air duct 210a, the second air duct module 220 has a transition air duct 220a, and the third air supply module 400 has an air supply air duct 230a. The transition air duct 220a connects the air supply air duct 230a and the outlet air duct 210a. The air supply module 400 and heating module 500 are installed within the air supply duct 230a of the third air duct module 230. An evaporator can also be installed within the air supply duct 230a. The air duct module 200 guides the gas from the receiving cavity 100a into the air supply duct 230a, where it is cooled by the evaporator before being guided to the transition duct 220a and the outlet duct 210a, ultimately being discharged back into the receiving cavity 100a, thus cooling the cavity 100a. The heating module 500, installed within the third air duct module 230, can perform heating and defrosting of components such as the evaporator within the third air duct module 230. A damper can be installed within the transition duct 220a, and adjusting the opening of the transition duct 220a, thereby regulating the gas flow rate in the outlet duct 210a, can also be used. The first air duct module 210 and the third air duct module 230 can be installed within the receiving cavity 100a, dividing the receiving cavity 100a into multiple chambers for easy categorized storage of items. The second air duct module 220 is located between the first air duct module 210 and the third air duct module 230. Placing the terminal module 300 on the second air duct module 220 helps to bring the terminal module 300 closer to components of the refrigeration equipment 1000, such as the damper and odor removal module, allowing the wiring terminals of the damper and odor removal module to also be connected to the terminal module 300. Furthermore, placing the terminal module 300 on the second air duct module 220 keeps it away from the refrigeration unit within the third air duct module 230, reducing the likelihood of frost buildup on the terminal module 300.

[0062] In some embodiments, the air duct module 200 further includes a fourth air duct module 240, which is also disposed between the first air duct module 210 and the third air duct module 230. The fourth air duct module 240 is connected to the receiving cavity 100a and the third air duct module 230. Specifically, the fourth air duct module 240 has a return air duct 240a, which is connected to the receiving cavity 100a and the supply air duct 230a of the third air duct module 230.

[0063] In some embodiments, the fourth air duct module 240 and the second air duct module 220 are spaced apart along the thickness direction of the housing 100, with the second air duct module 220 located on the side near the rear wall of the housing 100 and the fourth air duct module 240 located on the side near the door 600 of the housing 100.

[0064] In some embodiments, the second air duct module 220 and the fourth air duct module 240 are integrally formed.

[0065] like Figure 7 As shown, in some embodiments, the second air duct module 220 includes an air duct portion 221, a first connecting portion 222, and a second connecting portion 223. The air duct portion 221 has a transition air duct 220a, and an air damper is mounted on the air duct portion 221. Along the height direction of the housing 100, the first connecting portion 222 is disposed at the upper end of the air duct portion 221, and the second connecting portion 223 is disposed at the lower end of the air duct portion 221. The air duct portion 221 is fixedly connected to both the first connecting portion 222 and the second connecting portion 223. Along the thickness direction of the housing 100, both the first connecting portion 222 and the second connecting portion 223 are longer than the air duct portion 221. A terminal mounting cavity 220e is formed between the first connecting portion 222, the second connecting portion 223, and the air duct portion 221. The first connecting portion 222 is located below the first air duct module 210, supporting the first air duct module 210. The second connecting portion 223 is located above the third air duct module 230, limiting the position of the third air duct module 230. The first connecting part 222 can be fixedly connected to the first air duct module 210, and the second connecting part 223 can also be fixedly connected to the third air duct module 230. In these embodiments, the terminal module 300 is located inside the terminal mounting cavity 220e and is mounted on the second connecting part 223. This design utilizes the space of the first connecting part 222 and the second connecting part 223. After the terminal module 300 is installed inside the terminal mounting cavity 220e, the terminal module 300 will not occupy the space outside the second air duct module 220, which helps to reduce the overall size of the refrigeration equipment 1000.

[0066] In some embodiments, the second air duct module 220 is arranged along the thickness direction of the housing 100, and the terminal module 300 is located on the side of the second air duct module 220 away from the door 600.

[0067] The length of the second air duct module 220 is parallel to the thickness of the enclosure 100. The terminal module 300 is located on the side of the second air duct module 220 near the door 600, that is, on the side of the second air duct module 220 near the rear wall of the enclosure 100. With this design, the terminal connection line 800 connecting the terminal module 300 and the electrical control box 700 can be arranged between the rear wall of the enclosure 100 and the rear wall of the enclosure liner, providing more wiring space and facilitating wiring layout.

[0068] like Figures 8 to 11 As shown, in some embodiments, the air supply module 400 includes a volute 410, a fan 420, and an air supply connection line 430 electrically connected to the fan 420. The volute 410 is installed on the air duct module 200 and forms a fixed cavity 410a for installing the fan 420 with the air duct module 200. The fan 420 is installed on the air duct module 200 and located in the fixed cavity 410a. The air supply connection line 430 has an air supply terminal 431. The terminal module 300 is located above the volute 410. A wire hole 410b is provided on the side of the fixed cavity 410a away from the terminal module 300. The air supply connection line 430 passes through the wire hole 410b, and the air supply terminal 431 is inserted into the terminal module 300.

[0069] The volute 410 is installed on the inner wall of the air duct module 200, and together with the air duct module 200, forms a fixed cavity 410a for mounting the fan 420. The fan 420 is located inside the fixed cavity 410a and is fixedly connected to the air duct module 200. The volute 410 and the air duct module 200 together form the fixed cavity 410a, which helps to reduce the structural complexity of the volute 410, making its structure simpler and easier to manufacture for the refrigeration equipment 1000, reducing processing costs. It also helps to reduce the size of the third air duct module 230 in the width direction of the housing 100, making the structure more compact and allowing the housing cavity 100a to be designed with a larger volume to store more items. One end of the air supply connection line 430 is connected to the fan 420, and the other end has an air supply terminal 431, which is plugged into the terminal module 300 and electrically connected to the terminal module 300. Specifically, the air supply terminal 431 is plugged into the output terminal 312 of the terminal module 300. The terminal module 300 is located above the volute 410. A wire-passing hole 410b is provided on the side of the fixing cavity 410a away from the terminal module 300, that is, a wire-passing hole 410b is provided on the lower side of the fixing cavity 410a. The air supply connection cable 430 passes through the wire-passing hole 410b. With this design, after the air supply connection cable 430 is connected to the fan 420, the air supply connection cable 430 extends downward, then passes through the wire-passing hole 410b, and then extends upward to be plugged into the terminal module 300. The air supply connection cable 430 is U-shaped. The wire-passing hole 410b can limit the movement of the air supply connection cable 430, reduce the shaking of the air supply connection cable 430, and to a certain extent prevent the air supply connection cable 430 from contacting the impeller 422 of the fan 420.

[0070] In some embodiments, the fan 420 includes a mounting base 421 and a fan wheel 422 mounted on the mounting base 421. The mounting base 421 is mounted on the air duct module 200. The air supply connection line 430 is electrically connected to the fan 420. The mounting base 421 is provided with a first wire clip 4221. The inner wall of the air duct module 200 is provided with a clearance groove 230b extending along the height direction of the housing 100. The clearance groove 230b is used to avoid the air supply connection line 430. A second wire clip 231 is provided in the clearance groove 230b. The air supply connection line 431 is mounted on the first wire clip 4221 and the second wire clip 231.

[0071] The impeller 422 may include fan blades and a motor. The fan blades are mounted on the output shaft of the motor, and the motor is fixedly mounted on the mounting base 421. The mounting base 421 is fixedly mounted on the inner wall of the air duct module 200 and located within the fixing cavity 410a. A first wire clip 4221 is provided on the mounting base 421, allowing the air supply connection cable 430 to be clipped onto the first wire clip 4221, close to the mounting base 421, thus keeping the air supply connection cable 430 away from the fan blades of the impeller 422 to avoid the air supply connection cable 430 interfering with the rotation of the fan blades. A second wire clip 231 is provided within the clearance groove 230b, allowing the air supply connection cable 430 to be clipped onto the second wire clip 231, ensuring that the air supply connection cable 430 is located within the clearance groove 230b. Along the extending direction of the clearance groove 230b, multiple second wire clips 231 may be spaced apart within the clearance groove 230b to fix the air supply connection cable 430 at multiple points. With this design, under the action of the first line clip 4221 and the second line clip 231, the air supply connection line 430 is positioned close to the mounting base 421 and located in the clearance groove 230b, which can prevent the air supply connection line 430 from interfering with the rotation of the fan blades to a certain extent.

[0072] In some embodiments, the lower end of the clearance groove 230b extends out of the volute 410, such that the air duct module 200 and the volute 410 together form a wire hole 410b. After the air supply connection line 430 extends downward along the extension direction of the clearance groove 230b, it extends out of the clearance groove 230b through the wire hole 410b and is located outside the clearance groove 230b.

[0073] In some embodiments, along the height direction of the housing 100, a wire fixing structure 411 is provided on the side of the volute 410 away from the wire hole 410b. The wire fixing structure 411 is provided along the height direction of the housing 100, and the air supply connection line 430 is installed on the wire fixing structure 411.

[0074] The cable fixing structure 411 is used to fix the air supply connection cable 430. The cable fixing structure 411 is set along the height direction of the housing 100, so that the air supply connection cable 430 extends upward after passing through the wire hole 410b to connect with the terminal module 300 located above the volute 410. With this design, after the air supply connection cable 430 is electrically connected to the fan 420, it is first secured to the first wire clip 4221, then extends into the clearance groove 230b and is secured to the second wire clip 231, then passes out from the wire hole 410b at the lower end of the clearance groove 230b, and then is secured to the cable fixing structure 411, and finally connects to the terminal module 300. The cable fixing structure 411 on the volute 410 fixes the cable to the volute 410, preventing the cable from swinging freely and ensuring the safety of the refrigeration equipment 1000.

[0075] In some embodiments, the wire-fixing structure 411 is integrally formed with the volute 410.

[0076] In some embodiments, the wire fixing structure 411 is disposed on the outside of the volute 410, that is, on the outer surface of the volute 410. This design allows the wire fixing structure 411 to be used simultaneously to fix the heating connection wire 520 of the heating module 500.

[0078] The volute 410 is installed on the inner wall of the air duct module 200, and together with the air duct module 200, forms a fixed cavity 410a for mounting the fan 420. The fan 420 is located in the fixed cavity 410a and is fixedly connected to the air duct module 200. The air supply module 400 also includes an air supply connection line 430. One end of the air supply connection line 430 is connected to the fan 420, and the other end has an air supply terminal 431. The air supply terminal 431 is plugged into the terminal module 300 and electrically connected to the terminal module 300. The air supply connection line 430 can be installed on the fixed wire structure 411. The heating body 510 can generate heat, and it can be a heating tube. One end of the heating connection line 520 is connected to the heating body 510, and the other end has a heating terminal 521. The heating terminal 521 is plugged into the output terminal 312 of the terminal module 300. In these embodiments, the heating connection wire 520 is mounted on the fixed wire structure 411, which can prevent the heating connection wire 520 from swinging randomly and ensure the safety of the refrigeration equipment 1000.

[0079] In some embodiments, the heating module 500 is located below the air supply module 400, the air supply connection line 430 has an air supply terminal 431, the terminal module 300 is located above the volute 410, and a wire hole 410b is provided on the side of the fixing cavity 410a away from the terminal module 300.

Along the height direction of the housing 100, the wire fixing structure 411 is provided on the side of the volute 410 away from the wire hole 410b, and the wire fixing structure 411 is arranged along the height direction of the housing 100. Both the air supply connection line 430 and the heating connection line 520 are mounted on the wire fixing structure 411.

[0080] In some embodiments, the wire fixing structure 411 includes a third wire clip 4111 and a limiting plate 4112 spaced apart along the height direction of the housing 100. Both the third wire clip 4111 and the limiting plate 4112 are fixedly installed on the volute 410. A gap exists between the third wire clip 4111 and the side wall of the volute 410. The heating connection wire 520 and the air supply connection wire 430 are located in the gap and clamped by the third wire clip 4111 and the volute 410. The limiting plate 4112 and the side wall of the volute 410 together form a guide groove extending along the height direction of the housing 100. The guide groove limits the heating connection wire 520 and the air supply connection wire 430, both of which are located within the guide groove.

[0081] In some embodiments, two third line clips 4111 and a limiting plate 4112 are provided. The two third line clips 4111 are spaced apart along the height direction of the housing 100, and the limiting plate 4112 is provided between the two third line clips 4111.

[0082] In some embodiments, the wire fixing structure 411 further includes a winding member 4113, which is disposed on the side of the volute 410 near the wire through hole 410b. When the heating connecting wire 520 and the air supply connecting wire 430 are long, a portion of the heating connecting wire 520 and the air supply connecting wire 430 can be wound around the winding member 4113, making the heating connecting wire 520 and the air supply connecting wire 430 more compact.

[0083] In some embodiments, the winding member 4113 is located below the third wire clip 4111 and next to the wire hole 410b.

[0084] like Figure 12 and Figure 13 As shown, in some embodiments, the terminal module 300 includes a connection terminal 310, which has an input terminal 311 and an output terminal 312. The input terminal 311 is used for electrical connection with the electrical control box 700, and the output terminal 312 is electrically connected to the air supply wiring terminal 431 of the air supply module 400. The output terminal 312 is disposed inside the air duct module 200, and the input terminal 311 is located outside the air duct module 200.

[0085] In an embodiment where the refrigeration equipment includes a heating module 500, the output terminal 312 is also electrically connected to the heating terminal 521 of the heating module 500. The input terminal 311 of the connection terminal 310 is electrically connected to the control box 700, and the output terminal 312 is electrically connected to the air supply terminal 431 and the heating terminal 521, respectively. The output terminal 312 is located inside the air duct module 200, facilitating the connection between the air supply terminal 431, the heating terminal 521, and the output terminal 312. The control box 700 of the refrigeration equipment 1000 is located outside the air duct module 200, and the input terminal 311 is also located outside the air duct module 200, facilitating the electrical connection between the input terminal 311 and the control box 700.

[0086] like Figures 13 to 16 As shown, in some embodiments, the terminal module 300 further includes a junction box 320, which is installed in the air duct module 200. The junction box 320 has a mounting cavity 320a and an inlet hole 320b and a clearance hole 320c communicating with the mounting cavity 320a. The connection terminal 310 is installed in the junction box 320. The input terminal 311 of the connection terminal 310 is located in the mounting cavity 320a, and the output terminal 312 of the connection terminal 310 is located in the air duct module 200 through the clearance hole 320c.

[0087] Junction box 320 is fixedly installed on air duct module 200, and terminal module 300 is installed on junction box 320. Input terminal 311 of terminal module 300 is located inside mounting cavity 320a, and output terminal 312 extends into air duct module 200 through clearance hole 320c to connect with air supply terminal 431 and heating terminal 521 inside air duct module 200. Terminal connection wire 800, connecting terminal module 300 and electrical control box 700, enters mounting cavity 320a through inlet hole 320b and is electrically connected to input terminal 311. Connection terminal 310 is located inside junction box 320, which protects connection terminal 310 from damage caused by external impacts.

[0088] In some implementations, the duct module 200 has a mounting groove 220a, and a mounting hole 220b is provided at the bottom of the mounting groove 220a. The junction box 320 is installed in the mounting groove 220a, and part of the junction box 320 is located in the duct module 200 through the clearance hole 320c. The junction box 320 is sealed to the bottom wall of the mounting groove 220a.

[0089] The junction box 320 and the mounting groove 220a are sealed together to prevent moisture and other substances inside the duct module 200 from leaking out through the gap between the junction box 320 and the mounting groove 220a, thus affecting the normal operation of other components outside the duct module 200. The mounting hole 220b allows part of the junction box 320 to extend into the duct module 200, thereby allowing the output terminal 312 of the connection terminal 310 to be located inside the duct module 200.

[0090] To prevent moisture and other substances inside the duct module 200 from leaking out through the gap between the inner wall of the inlet hole 320b and the terminal connection wire 800, a sealing ring can be installed on the outer sleeve of the terminal connection wire 800. The inner wall of the sealing ring is sealed to the terminal connection wire 800, and the outer wall of the sealing ring is sealed to the inner wall of the inlet hole 320b.

[0091] In some embodiments, the junction box 320 includes a box body 321 and a box cover 322 that are sealed together. The box body 321 and the box cover 322 form a mounting cavity 320a and a wire inlet hole 320b. The box body 321 has a clearance hole 320c. The box body 321 is located in the mounting groove 220a and is sealed to the bottom wall of the mounting groove 220a. The connection terminal 310 is installed in the box body 321.

[0092] The box body 321 and the box cover 322 can be sealed together by means of tight fitting, setting a sealing gasket, sealing glue, etc. After the box body 321 and the box cover 322 are connected, they form an installation cavity 320a and a wire inlet hole 320b. With this design, when the terminal connection line 800 and the input terminal 311 are connected, the box cover 322 can be removed from the box body 321 for easy maintenance by the operator.

[0093] In some embodiments, the housing 321 includes an insertion portion 3211, a sealing connection portion 3212, a first mounting portion 3213, and a second mounting portion 3214. The first mounting portion 3213, the second mounting portion, and the insertion portion 3211 are all fixedly connected to the sealing connection portion 3212. The second mounting portion 3214 surrounds the outside of the first mounting portion 3213, forming a limiting groove 320d between them. A portion of the cover 322 is located within the limiting groove 320d and is connected to the second mounting portion 3214. The first mounting portion 3213, the sealing connection portion 3212, the insertion portion 3211, and the cover 322 together form a mounting cavity 320a. The first mounting portion 3213 and the cover 322 together form a wire inlet hole 320b. An avoidance hole 320c is provided on the insertion portion 3211, and the insertion portion 3211 is located within the mounting hole 220b. The sealing connection portion 3212 is sealed to the bottom of the mounting groove 220a.

[0094] The second mounting portion 3214 is disposed outside the first mounting portion 3213 and surrounds the first mounting portion 3213, with a gap between the first mounting portion 3213 and the second mounting portion 3214, thereby forming a limiting groove 320d. The lower part of the cover 322 is inserted into the limiting groove 320d, and the cover 322 is limited by the limiting groove 320d. The cover 322 and the second mounting portion 3214 can be fixedly connected by snap-fit, adhesive, or other methods. In some embodiments, a snap-fit ​​head is provided on the cover 322, and a snap-fit ​​groove is provided on the second mounting portion 3214. The cover 322 and the second mounting portion 3214 are fixedly connected together by snap-fit ​​of the snap-fit ​​head and the snap-fit ​​groove. In some embodiments, after the cover 322 and the second mounting part 3214 are engaged, the cover 322 is tightly fitted with the sealing connection part 3212 and the first mounting part 3213, so that the cover 322 and the sealing connection part 3212 are sealed together, and the cover 322 and the first mounting part 3213 are sealed together. The sealing connection part 3212 and the bottom of the mounting groove 220a can be sealed together by setting a sealing gasket, setting a sealant, etc. In some embodiments, the sealing connection part 3212 and the second air duct module 220 are engaged. After the sealing connection part 3212 and the second air duct module 220 are engaged, the sealing connection part 3212 is tightly fitted with the bottom of the mounting groove 220a, thereby achieving a sealed connection between the sealing connection part 3212 and the bottom of the mounting groove 220a.

[0095] like Figure 14 As shown, in some embodiments, the bottom of the mounting groove 220a is set at an angle to the height direction of the box 100, that is, the bottom of the mounting groove 220a is set at an angle to the horizontal plane. This design makes it easy to remove the box 321 from the second air duct module 220.

[0096] In some embodiments, the thickness of the door of the refrigeration equipment is 25mm to 40mm, and the total thickness of the cabinet and the door is 450mm to 600mm.
