Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigeration device. Background Technology

[0002] Refrigeration equipment such as refrigerators and freezers are essential equipment in people's production and daily life. They can be used to store food and beverages, build cold chain transportation systems, and preserve vaccines, plasma, or biological samples.

[0003] Refrigeration equipment typically includes a storage chamber, a defrosting water pipe connected to the storage chamber, and an evaporating dish. During the operation of the refrigeration equipment, water vapor in the storage chamber may condense into defrosting water upon contact with the cold air. The defrosting water pipe is used to drain the defrosting water from the storage chamber to the evaporating dish to prevent it from freezing in the storage chamber.

[0004] However, when users turn on the refrigeration equipment, the drop in air pressure in the storage compartment may cause defrost water in the defrost pipe or evaporator to be siphoned back into the storage compartment, which in turn prevents the defrost water from draining smoothly, causing problems such as ice formation in the storage compartment. Utility Model Content

[0005] This application discloses a refrigeration device that can smoothly drain defrost water from the storage chamber.

[0006] To achieve the above objectives, this application discloses a refrigeration device, comprising: a housing, a heat exchange assembly, and a water receiving assembly. The housing has a storage chamber and a compressor compartment, with the compressor compartment located below the storage chamber. The bottom of the storage chamber has a defrost water pipe for discharging defrost water, and the defrost water pipe has a defrost water outlet.

[0007] The heat exchange assembly includes a compressor, a condenser, an expansion valve, and an evaporator. The compressor and condenser are both located in the compressor compartment. The evaporator is configured to exchange heat with the storage chamber. The compressor, condenser, expansion valve, and evaporator are connected in sequence through heat exchange pipelines, and refrigerant flows through the heat exchange pipelines to cool the storage chamber through the phase change of the refrigerant.

[0008] The water receiving assembly is located inside the compressor compartment and includes a drain pipe and an evaporating dish. The drain pipe is connected to a defrost water pipe, and the evaporating dish is located below the drain pipe to collect defrost water. The drain pipe includes a pipe body, the inner wall of which forms a drain passage. The drain passage has an inlet at a first end of the pipe body and a drain outlet at a second end of the pipe body. The inlet is configured to communicate with the defrost water pipe, and the drain outlet is configured to face the evaporating dish.

[0009] The outer wall of the pipe body is provided with a first air inlet that is connected to the drainage pipe. The first air inlet is located at the first end of the pipe body, and the orientation of the first air inlet is the same as that of the water inlet. The first air inlet is configured to allow air from outside the drainage pipe to enter the drainage pipe through the first air inlet.

[0010] With the above configuration, defrost water in the storage chamber can be discharged from the defrost water outlet of the defrost water pipe into the drain pipe of the drain pipe, and then discharged into the evaporating dish through the drain outlet, thus ensuring timely discharge of defrost water from the storage chamber. Furthermore, when the air pressure in the storage chamber drops due to the user turning on the refrigeration equipment or other reasons, air outside the drain pipe can enter the drain pipe through the first air inlet, and then enter the storage chamber through the defrost water pipe, balancing the air pressure inside the storage chamber, preventing defrost water from being siphoned back into the storage chamber, and ensuring that defrost water can be smoothly discharged from the storage chamber, avoiding problems such as ice formation in the storage chamber. Simultaneously, the orientation of the first air inlet and the water inlet is the same, which reduces or even prevents hot air generated by the condenser or compressor from directly entering the drain pipe and then the storage chamber through the defrost water pipe, thus preventing ice formation and blockage in the drain pipe and defrost water pipe, and preventing the storage chamber temperature from rising, increasing the compressor load, and reducing the energy consumption of the refrigeration equipment.

[0011] Optionally, part of the pipe wall protrudes outward to form an air inlet chamber connected to the side of the drain pipe. The inner wall of the air inlet chamber is configured to form an air inlet channel together with the outer wall of the defrost water pipe. In the extension direction of the pipe body, the first end of the air inlet channel is higher than the defrost water outlet and connected to the first air inlet. The second end of the air inlet channel is lower than the defrost water outlet and connected to the drain pipe.

[0012] With the above configuration, when the defrost water pipe is inserted into the first end of the pipe body, the outer wall of the defrost water pipe and the inner wall of the air inlet chamber together form an air inlet channel. Air from outside the drain pipe can enter the drain pipe through the first air inlet and the air inlet channel, and then enter the storage chamber through the defrost water pipe. This balances the air pressure in the storage chamber, prevents defrost water from being siphoned back into the storage chamber, and ensures that defrost water can be smoothly discharged from the storage chamber, avoiding problems such as ice formation in the storage chamber.

[0013] Optionally, the air intake chamber extends to the first end of the pipe body and communicates with the edge of the first air inlet. This configuration makes the drain pipe structure more compact.

[0014] Optionally, the extension direction of the air intake chamber is parallel to the extension direction of the pipe body. The air intake chamber has a first air intake section and a second air intake section that are interconnected. In the extension direction of the air intake chamber, the first air inlet, the first air intake section and the second air intake section are arranged in sequence, and the first air intake section is connected between the first air inlet and the second air intake section. The cross-section of the first air intake section and the cross-section of the first air inlet have the same shape. Along the direction from the first end of the air intake chamber to the second end of the air intake chamber, the convexity of the pipe wall corresponding to the second air intake section gradually decreases, so that the cross-sectional area of ​​the second air intake section gradually decreases.

[0015] With the above configuration, the first and second air intake sections can guide the air in the air intake channel into the drain pipe, and then into the storage chamber through the defrost water pipe to balance the air pressure in the storage chamber and allow the defrost water in the storage chamber to be discharged smoothly.

[0016] Optionally, the outer wall of the pipe body is also provided with a second air inlet that communicates with the air inlet chamber. Compared with the second end of the air inlet chamber, the second air inlet is closer to the first end of the air inlet chamber, and the second air inlet is configured to be higher than the defrost water outlet.

[0017] With the above configuration, when the first air inlet is blocked due to unforeseen circumstances, air from outside the drain pipe can still enter the drain pipe through the second air inlet and the air intake channel, and then enter the storage chamber through the defrost water pipe. This balances the air pressure inside the storage chamber, prevents defrost water from being siphoned back into the storage chamber, and ensures that the defrost water can be smoothly discharged from the storage chamber, avoiding problems such as ice formation in the storage chamber.

[0018] Optionally, the orientation of the second air inlet forms an angle with the extension direction of the pipe body. This arrangement helps to prevent the second air inlet from becoming blocked.

[0019] Optionally, the first air inlet and the water inlet are configured to be at the same height. With the above configuration, the height of the first air inlet is higher than the height of the defrost water outlet, which can prevent defrost water in the drain pipe from overflowing from the first air inlet.

[0020] Optionally, the inner wall of the pipe body is provided with a snap-fit ​​protrusion extending circumferentially along the pipe body, and the defrosting water pipe is provided with a snap-fit ​​groove that matches the snap-fit ​​protrusion. The pipe body and the defrosting water pipe are configured to snap together by the snap-fit ​​protrusion and the snap-fit ​​groove, and the height of the first air inlet is higher than or equal to the height of the snap-fit ​​protrusion.

[0021] By implementing the above design, defrost water in the drain pipe can be prevented from overflowing from the first air inlet and flowing onto components other than the evaporator plate, thus avoiding damage to the refrigeration equipment and extending its service life. Furthermore, preventing defrost water from overflowing from the first air inlet and flowing outside the refrigeration equipment eliminates potential safety hazards.

[0022] Optionally, the second end of the tube has a corrugated section. With the above configuration, the corrugated section can adjust the orientation of the drain outlet by its own deformation, so that the drain outlet faces the evaporating dish and the defrosting water in the drain pipe is discharged into the evaporating dish.

[0023] Optionally, the heat exchange assembly also includes a condenser fan, which is located between the compressor and the condenser. With this configuration, the condenser fan can drive gas flow through the condenser, thereby improving the efficiency of the condenser in releasing heat to the external environment of the refrigeration equipment, and thus enhancing the cooling effect of the refrigeration equipment.

[0032] As mentioned in the background section, refrigerators, freezers, and other refrigeration equipment are indispensable in people's daily lives and production. They are used to store food and beverages, build cold chain transportation systems, and preserve vaccines, plasma, or biological samples. Refrigeration equipment typically includes a storage compartment, a defrost water pipe connected to the storage compartment, and an evaporating dish. During operation, water vapor in the storage compartment may condense into defrost water. The defrost water pipe drains this water from the storage compartment to the evaporating dish to prevent it from freezing in the storage compartment. However, when the user turns on the refrigeration equipment, the pressure drop in the storage compartment may cause the defrost water in the defrost water pipe or evaporating dish to be siphoned back into the storage compartment, preventing proper drainage and leading to problems such as freezing in the storage compartment.

[0033] To address the aforementioned problems, this application provides a refrigeration device to solve the problem in the related art where defrosting water cannot be discharged smoothly, causing the storage compartment to freeze.

[0034] Please refer to Figures 1 to 4 The refrigeration equipment 10 of this application embodiment includes: a housing 11, a heat exchange component, and a water receiving component 16. The housing 11 has a storage chamber 11a and a compressor compartment 11b, with the compressor compartment 11b located below the storage chamber 11a. The bottom of the storage chamber 11a has a defrost water pipe 12 for discharging defrost water, and the defrost water pipe 12 has a defrost water outlet 12a.

[0035] The heat exchange assembly includes a compressor 14, a condenser 13, an expansion valve, and an evaporator. The compressor 14 and the condenser 13 are both located in the compressor compartment 11b. The evaporator is configured to exchange heat with the storage chamber 11a. The compressor 14, the condenser 13, the expansion valve, and the evaporator are connected in sequence through heat exchange pipes, and refrigerant flows through the heat exchange pipes to cool the storage chamber 11a through the phase change of the refrigerant.

[0036] A water receiving assembly 16 is disposed within the compressor compartment 11b. The water receiving assembly 16 includes a drain pipe 16a and an evaporating dish 16b. The drain pipe 16a is connected to the defrost water pipe 12, and the evaporating dish 16b is disposed below the drain pipe 16a to collect defrost water. The drain pipe 16a includes a pipe body 100, the inner wall of which forms a drain pipe 200. The drain pipe 200 has an inlet 210 at a first end 110 of the pipe body and a drain outlet 220 at a second end 120 of the pipe body. The inlet 210 is configured to communicate with the defrost water pipe 12, and the drain outlet 220 is configured to face the evaporating dish 16b.

[0037] The outer wall of the pipe body 100 is provided with a first air inlet 300 that communicates with the drain pipe 200. The first air inlet 300 is located at the first end 110 of the pipe body, and the orientation of the first air inlet 300 is the same as that of the water inlet 210. The first air inlet 300 is configured to allow air outside the drain pipe 16a to enter the drain pipe 200 through the first air inlet 300.

[0038] With the above configuration, the defrost water in storage chamber 11a can be discharged from the defrost water outlet 12a of defrost water pipe 12 into the drain pipe 200 of drain pipe 16a, and then discharged into evaporating dish 16b through drain outlet 220, thereby ensuring timely discharge of defrost water from storage chamber 11a. Furthermore, when the air pressure in storage chamber 11a drops due to the user turning on the refrigeration equipment 10 or other reasons, air outside drain pipe 16a can enter drain pipe 16a through the first air inlet 300, and then enter storage chamber 11a through defrost water pipe 12, thus balancing the air pressure in storage chamber 11a, preventing defrost water from being siphoned back into storage chamber 11a, and ensuring that defrost water can be smoothly discharged from storage chamber 11a, preventing problems such as freezing in storage chamber 11a. Meanwhile, the orientation of the first air inlet 300 is the same as that of the water inlet 210, which can reduce or even prevent the hot air generated by the operation of the condenser 13 or the compressor 14 from directly entering the drain pipe 16a and then entering the storage chamber 11a through the defrost water pipe 12. This avoids ice blockage in the drain pipe 16a and the defrost water pipe 12, as well as avoids the temperature rise in the storage chamber 11a and the increased load on the compressor 14, thereby reducing the energy consumption of the refrigeration equipment 10.

[0039] The components and technical solutions of the refrigeration equipment 10 of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0040] The refrigeration device 10 in this application embodiment may include at least one of the following devices with refrigeration function: refrigerator, freezer, food display case, or cold storage box. The following embodiments of this application will use a refrigerator as an example of the refrigeration device 10, but the refrigeration device 10 is not limited to a refrigerator.

[0041] Please refer to Figure 1 The refrigeration equipment 10 includes a housing 11, which supports and protects other components within the refrigeration equipment 10. The housing 11 has a storage chamber 11a, which can be used to store food or beverages. The housing 11 may be equipped with an openable door to allow the storage chamber 11a to be opened or closed, enabling users to retrieve food or beverages from the storage chamber 11a.

[0042] The bottom of the storage chamber 11a has a defrost water pipe 12, which is connected to the inside of the storage chamber 11a and has a defrost water outlet 12a. The defrost water in the storage chamber 11a can be discharged from the defrost water pipe 12 and the defrost water outlet 12a.

[0043] The housing 11 also has a compressor compartment 11b, which is located below the storage chamber 11a in the height direction of the refrigeration equipment 10 and is used to house other components of the refrigeration equipment 10. For example, the height dimension of the compressor compartment 11b in the height direction of the refrigeration equipment 10 may be less than or equal to 165 mm.

[0044] The refrigeration equipment 10 also includes a heat exchange component, which includes an evaporator (not shown in the figure). The evaporator can be located outside the storage chamber 11a. Refrigerant can flow inside the evaporator, and the refrigerant can undergo a phase change inside the evaporator to exchange heat between the evaporator and the storage chamber 11a. The evaporator can absorb heat from the storage chamber 11a to cool the storage chamber 11a and achieve the refrigeration function.

[0045] The heat exchange assembly also includes a condenser 13, which may be located within the compressor compartment 11b. The condenser 13 is connected to the evaporator and is used to receive the refrigerant flowing out of the evaporator. The refrigerant can circulate and undergo a phase change within the condenser 13, allowing the condenser 13 to exchange heat with the external environment of the refrigeration equipment 10. The condenser 13 can release the heat absorbed by the refrigerant to the outside of the refrigeration equipment 10.

[0046] The heat exchange assembly also includes an expansion valve (not shown in the figure), which can be located within the compressor compartment 11b and connected between the condenser 13 and the evaporator. As the refrigerant flows from the condenser 13 to the evaporator, the expansion valve can adjust its opening to regulate the refrigerant pressure.

[0047] The heat exchange assembly also includes a compressor 14, which may be located within a compressor compartment 11b and spaced apart from the condenser 13 in the width direction of the refrigeration equipment 10. The compressor 14 communicates between the evaporator and the condenser 13, and is used to draw refrigerant from the evaporator and compress it, as well as to drive the compressed refrigerant into the condenser 13.

[0048] The heat exchange assembly also includes heat exchange piping (not shown in the figure), which is used to circulate refrigerant and is connected in sequence between the compressor 14, the condenser 13, the expansion valve and the evaporator, so that the compressor 14 can drive the refrigerant to circulate within the heat exchange assembly, thereby realizing the refrigeration function of the refrigeration equipment 10.

[0049] In one example, the heat exchange assembly may further include a condenser fan 15, which may be located within the compressor compartment 11b. In the width direction of the refrigeration device 10, the condenser fan 15 may be positioned between the compressor 14 and the condenser 13. The condenser fan 15 drives gas flow through the condenser 13 to improve the efficiency of the condenser 13 in releasing heat to the external environment of the refrigeration device 10, thereby improving the refrigeration efficiency and cooling effect of the refrigeration device 10.

[0050] Please combine Figure 2 and Figure 3 The refrigeration equipment 10 also includes a water receiving assembly 16, which is located within the compressor compartment 11b. The water receiving assembly 16 includes a drain pipe 16a, which can be located between the compressor 14 and the condenser fan 15 in the width direction of the refrigeration equipment 10. The drain pipe 16a is connected to and communicates with the defrost water pipe 12, allowing defrost water discharged from the defrost water outlet 12a to flow into the drain pipe 16a.

[0051] The water receiving assembly 16 also includes an evaporating dish 16b, which is located below the drain pipe 16a in the height direction of the refrigeration unit 10, and may be located below the compressor 14, the condenser fan 15, and the condenser 13. The evaporating dish 16b is used to receive defrost water discharged from the drain pipe 16a, and the defrost water can evaporate to dryness in the evaporating dish 16b.

[0052] Therefore, the defrost water in storage chamber 11a can be discharged from the defrost water outlet 12a of defrost water pipe 12 into the drain pipe 200 of drain pipe 16a, and then discharged from the drain outlet 220 into evaporating dish 16b, to avoid problems such as bacterial growth, food and beverage contamination, or freezing caused by defrost water in storage chamber 11a. Furthermore, the compressor 14 is located above evaporating dish 16b, and the heat generated during the operation of compressor 14 can accelerate the evaporation rate of defrost water in evaporating dish 16b, so as to evaporate the defrost water in a timely manner.

[0053] In one example, the refrigeration device 10 may also include a tray 17 located at the bottom of the compressor compartment 11b, on which the compressor 14 and the evaporating dish 16b may both be mounted.

[0054] Understandable, Figure 1 , Figure 2 and Figure 3 This is only used to illustrate the positional relationship between the components of the refrigeration device 10 in one embodiment of this application, and does not limit the shape, structure, size or connection relationship of the components in the refrigeration device 10.

[0055] Please refer to Figure 4 This application provides a drain pipe 16a, which includes a pipe body 100. The material used to make the pipe body 100 may include at least one of the following: nylon (polyamide, abbreviated as PA), acrylonitrile butadiene styrene (ABS) plastic, or polypropylene (PP).

[0056] Please refer to Figure 5The pipe body 100 forms a drainage pipe 200, which can extend along the extension direction of the pipe body 100, that is, the extension direction of the drainage pipe 200 can be parallel to the extension direction of the pipe body 100. In the extension direction of the pipe body 100, the first end 110 and the second end 120 of the pipe body are arranged at intervals.

[0057] The drainage pipe 200 has an inlet 210 and an outlet, which are located at the two ends of the drainage pipe 200 respectively. The inlet 210 is located at the first end 110 of the pipe body, and the outlet is located at the second end 120 of the pipe body.

[0058] Among them, such as Figure 3 As shown, the first end 110 of the pipe is connected to the defrost water pipe 12, and correspondingly, the inlet 210 of the drain pipe 200 is connected to the defrost water outlet 12a. Thus, the defrost water in the storage chamber 11a can be discharged into the drain pipe 200 through the defrost water outlet 12a.

[0059] In some implementation methods, please combine Figure 3 and Figure 5 The inner wall of the pipe body 100 is provided with a snap-fit ​​protrusion 130, which is located closer to the first end 110 of the pipe body than the second end 120. The defrost water pipe 12 may be provided with a snap-fit ​​groove that matches the snap-fit ​​protrusion 130, allowing the snap-fit ​​protrusion 130 to snap into the groove. Correspondingly, in the height direction of the refrigeration equipment 10, the height of the water inlet 210 is higher than the height of the snap-fit ​​protrusion 130 and the snap-fit ​​groove, and the height of the snap-fit ​​protrusion 130 and the snap-fit ​​groove is higher than the height of the defrost water outlet 12a.

[0060] Thus, at least part of the defrosting water pipe 12 can be inserted into the first end 110 of the pipe body. The defrosting water pipe 12 can be snapped into place by the snap-fit ​​groove and the snap-fit ​​protrusion 130 on the inner wall of the pipe body 100, so as to detachably connect the drain pipe 16a and the defrosting water pipe 12.

[0061] In one example, please combine Figure 5 and Figure 6 The snap-fit ​​protrusion 130 can extend circumferentially along the pipe body 100 to form a ring or near-ring. This allows the drain pipe 16a to be securely snapped onto the defrosting water pipe 12. In another example, there can be multiple snap-fit ​​protrusions 130, spaced apart circumferentially along the pipe body 100. Correspondingly, there can also be multiple snap-fit ​​grooves, each corresponding to a different snap-fit ​​protrusion 130.

[0062] Of course, in some other implementations, the snap-fit ​​protrusion 130 can also be provided on the inner wall of the pipe body 100, and correspondingly, the snap-fit ​​groove can also be provided on the defrosting water pipe 12.

[0063] In other implementations, the drain pipe 16a and the defrosting pipe 12 can also be connected by at least one of the following methods: adhesive bonding, threaded connection, or heat fusion connection. Alternatively, the drain pipe 16a and the defrosting pipe 12 can also be connected by external structures such as cable ties, hose clamps, or clamps.

[0064] like Figure 2 As shown, when the drain pipe 16a is connected to the defrost water pipe 12, the extension direction of the drain pipe 16a can be parallel or approximately parallel to the height direction of the refrigeration equipment 10. Correspondingly, the first end 110 and the second end 120 of the pipe are arranged along the defrost water pipe 12 towards the evaporator 16b. The first end 110 and the inlet 210 of the pipe face towards the storage chamber 11a, while the second end 120 and the drain outlet 220 face towards the evaporator 16b. Thus, the defrost water in the storage chamber 11a can be discharged sequentially into the evaporator 16b through the defrost water outlet 12a, the drain pipe 200, and the drain outlet 220.

[0065] In some implementation methods, please combine Figure 2 and Figure 4 The second end 120 of the tube body has a corrugated pipe section 140, and the drain outlet 220 is located on the side of the corrugated pipe section 140 away from the first end 110 of the tube body. With the above arrangement, the corrugated pipe section 140 can adjust the orientation of the drain outlet 220 by its own deformation, so that the drain outlet 220 faces the evaporating dish 16b and drains the defrosting water in the drain pipe 16a into the evaporating dish 16b.

[0066] Please refer to Figure 4 and Figure 5 The outer wall of the pipe body 100 is provided with a first air inlet 300, which is located at the first end 110 of the pipe body and is connected to the drain pipe 200. Thus, air outside the drain pipe 16a can enter the drain pipe 16a through the first air inlet 300, and then enter the storage chamber 11a through the defrost water pipe 12. When the air pressure in the storage chamber 11a drops due to the user turning on the refrigeration equipment 10 or other reasons, the air outside the drain pipe 16a entering the storage chamber 11a through the first air inlet 300 can balance the air pressure in the storage chamber 11a, preventing defrost water from being siphoned back into the storage chamber 11a, ensuring that the defrost water can be discharged smoothly, thereby preventing problems such as bacterial growth, food and beverage contamination, or freezing of defrost water in the storage chamber 11a.

[0067] In the example above, please combine Figure 2 and Figure 4The first air inlet 300 faces the same direction as the water inlet 210, that is, the first air inlet 300 faces the storage chamber 11a along the direction from the second end 120 of the pipe body to the first end 110 of the pipe body. Correspondingly, the first air inlet 300 does not face the condenser 13, condenser fan 15 or compressor 14 in the compressor compartment 11b.

[0068] With the above settings, the hot air generated by the operation of the condenser 13 or compressor 14 can be reduced or even avoided from being blown into the drain pipe 16a and into the defrost water pipe 12 and storage chamber 11a under the drive of the condenser fan 15. This avoids the icing and blockage of the drain pipe 16a and defrost water pipe 12, and also avoids the temperature rise in the storage chamber 11a and the increased load on the compressor 14, thereby reducing the energy consumption of the refrigeration equipment 10.

[0069] The shape of the first air inlet 300 is not limited in this embodiment. The first air inlet 300 can be any of the following shapes: rectangular, approximately rectangular, circular, elliptical, trapezoidal, or polygonal.

[0070] In the example above, please refer to Figure 7 In the height direction of the refrigeration equipment 10, the height of the first air inlet 300 is higher than or equal to the height of the snap-fit ​​protrusion 130. This can also be understood as the distance between the first air inlet 300 and the second end 120 of the pipe body being greater than or equal to the distance between the snap-fit ​​protrusion 130 and the second end 120 of the pipe body. Correspondingly, in the height direction of the refrigeration equipment 10, the height of the first air inlet 300 is higher than the height of the defrost water outlet 12a of the defrost water pipe 12.

[0071] By implementing the above-mentioned design, defrost water in the drain pipe 16a can be prevented from overflowing from the first air inlet 300 and flowing onto other components besides the evaporator dish 16b, such as the tray 17. This prevents damage to the refrigeration equipment 10 and thus property loss, extending the service life of the refrigeration equipment 10. Furthermore, preventing defrost water from overflowing from the first air inlet 300 and flowing outside the refrigeration equipment 10 eliminates potential safety hazards.

[0072] In one embodiment, the first air inlet 300 and the water inlet 210 are configured to be at the same height in the height direction of the refrigeration device 10. This can also be understood as the distance between the first air inlet 300 and the second end 120 of the pipe body being equal to the distance between the water inlet 210 and the second end 120 of the pipe body. Therefore, the height of the first air inlet 300 is higher than the height of the defrost water outlet 12a, which prevents defrost water in the drain pipe 16a from overflowing from the first air inlet 300.

[0073] In another example, the height of the first air inlet 300 may also be higher than the height of the water inlet 210. Alternatively, in yet another example, the height of the first air inlet 300 may be lower than the height of the water inlet 210 and higher than or equal to the height of the snap-fit ​​protrusion 130.

[0074] For some implementation methods, please refer to Figure 6 The first air inlet 300 and the water inlet 210 can be arranged radially along the drain pipe 16a, with the first air inlet 300 located outside the water inlet 210. The first air inlet 300 and the water inlet 210 can be radially interconnected, forming a single opening. This makes the structure of the drain pipe 16a more compact. The first air inlet 300 can be formed by protruding outward from a portion of the sidewall of the water inlet 210.

[0075] In other implementations, the first air inlet 300 and the water inlet 210 can also be set alternately.

[0076] In one embodiment, please combine Figure 5 and Figure 7 A portion of the pipe wall of the pipe body 100 protrudes outward to form an air inlet chamber 400 that communicates with the drain pipe 200, and the air inlet chamber 400 and the drain pipe 200 are arranged radially in the drain pipe 16a. That is, the air inlet chamber 400 is connected to the side of the drain pipe 200.

[0077] The intake chamber 400 is also located at the first end 110 of the tube body, such as Figure 3 As shown, when the defrosting water pipe 12 is inserted into the first end 110 of the pipe body, the outer wall of the defrosting water pipe 12 and the inner wall of the air inlet chamber 400 together form an air inlet channel 500. The air inlet channel 500 can extend along the extension direction of the pipe body 100, that is, the extension direction of the air inlet channel 500 can be parallel or approximately parallel to the extension direction of the pipe body 100. Furthermore, in the extension direction of the air inlet channel 500, the first end of the air inlet channel 500 is closer to the water inlet 210 than the second end of the air inlet channel 500.

[0078] In the height direction of the refrigeration equipment 10, the first end of the air intake channel 500 can be higher than the defrost water outlet 12a and connected to the first air intake 300; the second end of the air intake channel 500 can be lower than the defrost water outlet 12a and connected to the drain pipe 200.

[0079] With the above configuration, when the defrost water pipe 12 is inserted into the first end 110 of the pipe body, the outer wall of the defrost water pipe 12 and the inner wall of the air inlet chamber 400 together form an air inlet channel 500. Air outside the drain pipe 16a can enter the drain pipe 16a through the first air inlet 300 and the air inlet channel 500, and then enter the storage chamber 11a through the defrost water pipe 12. This can balance the air pressure in the storage chamber 11a, prevent defrost water from being siphoned back into the storage chamber 11a, and ensure that defrost water can be smoothly discharged from the storage chamber 11a, avoiding problems such as freezing in the storage chamber 11a.

[0080] In one embodiment, please combine Figure 3 and Figure 5 The air intake chamber 400 can extend along the extension direction of the air intake channel 500, with the first end of the air intake channel 500 being the first end of the air intake chamber 400 and the second end of the air intake channel 500 being the second end of the air intake chamber 400. Correspondingly, the extension direction of the air intake chamber 400 can be parallel or approximately parallel to the extension direction of the pipe body 100. The air intake chamber 400 can extend to the first end 110 of the pipe body and connect with the first air inlet 300 and the edge of the first air inlet 300 near the water inlet 210. This makes the structure of the drain pipe 16a more compact.

[0081] In one embodiment, please continue to refer to Figure 5 The intake chamber 400 has a first intake section 410 and a second intake section 420, which are arranged and interconnected in the extending direction of the intake chamber 400. The first intake section 410 is closer to the first intake port 300 than the second intake section 420, and the first intake section 410 connects the second intake section 420 and the first intake port 300. Thus, the first intake port 300, the first intake section 410, and the second intake section 420 are arranged sequentially in the extending direction of the intake chamber 400.

[0082] The cross-sectional shape of the first air intake section 410 is the same as that of the first air intake port 300, and the dimensions remain unchanged. It can also be understood that the first air intake section 410 can be formed by translating the first air intake port 300 along the extension direction of the air intake cavity 400.

[0083] Along the direction from the first end of the intake chamber 400 to the second end of the intake chamber 400, the degree of outward bulging of the pipe wall of the pipe body 100 corresponding to the second intake section 420 gradually decreases, so that the cross-sectional area of ​​the second intake section 420 gradually decreases.

[0084] Furthermore, in the radial direction of the drain pipe 16a, the second air intake section 420 is connected to the drain pipe 200 on the side closest to it, and in the height direction of the refrigeration equipment 10, the height of the second air intake section 420 is lower than the height of the defrost water outlet 12a. This allows air in the air intake passage 500 to enter the drain pipe 200, as well as the defrost water pipe 12 and the storage chamber 11a, through the second air intake section 420.

[0085] With the above configuration, the first air intake section 410 and the second air intake section 420 can guide the air in the air intake channel 500 into the drain pipe 200, and then into the storage chamber 11a through the defrost water pipe 12 to balance the air pressure in the storage chamber 11a, so that the defrost water in the storage chamber 11a can be discharged smoothly.

[0086] Of course, in the radial direction of the drain pipe 16a, the side of the first air intake section 410 near the drain pipe 200 can also be connected to the drain pipe 200, and the air in the air intake channel 500 can also enter the drain pipe 200 from the first air intake section 410.

[0087] In one embodiment, please refer to Figure 5 and Figure 8 The outer wall of the pipe body 100 is also provided with a second air inlet 600 communicating with the air inlet chamber 400. The second air inlet 600 can be located on the outwardly protruding part of the pipe wall of the pipe body 100 and communicate with the air inlet chamber 400. Compared with the second end of the air inlet chamber 400, the second air inlet 600 is closer to the first end of the air inlet chamber 400 and is located close to the first air inlet 300. In the height direction of the refrigeration device 10, the second air inlet 600 is configured to be higher than the defrost water outlet 12a.

[0088] With the above configuration, when the first air inlet 300 is blocked due to unforeseen circumstances, air outside the drain pipe 16a can still enter the drain pipe 16a through the second air inlet 600 and the air intake channel 500, and then enter the storage chamber 11a through the defrost water pipe 12. This balances the air pressure inside the storage chamber 11a, prevents defrost water from being siphoned back into the storage chamber 11a, and ensures that the defrost water can be smoothly discharged from the storage chamber 11a, thus preventing problems such as ice formation in the storage chamber 11a.

[0089] In one embodiment, please combine Figure 7 and Figure 9 The orientation of the second air inlet 600 forms an angle with the extension direction of the pipe body 100. For example, the orientation of the second air inlet 600 can be perpendicular or approximately perpendicular to the extension direction of the pipe body 100. This helps to prevent the second air inlet 600 from becoming blocked.

[0090] The shape of the second air inlet 600 is not limited in this application embodiment. The second air inlet 600 can be any of the following shapes: rectangular, approximately rectangular, circular, elliptical, trapezoidal or polygonal.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
