Description

The door body is used to open or close the cold storage room. The cold storage room is used to keep items to be placed cold. The internal temperature of the cold storage room is lower than the air temperature in the external environment. When the door body of the refrigeration equipment is opened or closed, the air convection speed between the air inside the cold storage room and the air in the air increases, and the higher temperature gas in the air will enter the cold storage room. After the refrigeration equipment is closed, when the water vapor in the air hits the inner wall of the refrigeration equipment, heat transfer from the water vapor to the inner wall of the refrigeration equipment will occur, the internal energy of the water vapor molecules will decrease, the movement speed of the water vapor molecules will slow down, and the water vapor will change from gas to liquid water. The liquefied liquid water will adhere to the surface of the inner wall of the refrigeration equipment. When the liquid water reaches a certain volume, it will slide along the inner wall of the refrigeration equipment under the action of gravity.

One end of the guide pipe is connected to the refrigeration chamber, and the other end of the guide pipe is connected to the water receiving tray.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0043] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0044] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0045] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0046] Refrigeration equipment is equipment used to store food, medicines and other perishable items. The refrigeration equipment provided in the embodiments of the present application may include refrigerators, display cabinets, refrigerated trucks and cold storages, etc. The refrigeration equipment prevents the growth of bacteria and microorganisms by adjusting the temperature and humidity, thereby extending the shelf life of food and keeping the food fresh and safe.

[0047] In the related art, the refrigeration equipment is mainly composed of a compressor, an evaporator, a condenser, a capillary tube, a filter dryer and a connecting pipe. The compressor, the evaporator and the condenser are connected through the connecting pipe. The capillary tube and the filter dryer are sequentially arranged between the evaporator and the condenser, and the compressor is loaded with a refrigerant.

[0048] The low-pressure gaseous refrigerant is compressed into a high-temperature, high-pressure superheated gas in the compressor and then discharged into the condenser. Subsequently, the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continues to drop, gradually being cooled into a high-temperature, high-pressure saturated steam, and further cooled into a saturated liquid; the saturated liquid is filtered out of moisture and impurities by a drying filter and flows into the capillary tube, where it is throttled and depressurized, and the refrigerant becomes a normal-temperature, low-pressure gas. The normal-temperature, low-pressure refrigerant gas begins to absorb heat and vaporize in the evaporator, which not only reduces the temperature of the evaporator and the surrounding area, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, and the above process is repeated to transfer the heat in the refrigeration equipment to the air outside the refrigeration equipment, thereby achieving internal refrigeration of the refrigeration equipment.

[0049] The refrigeration equipment also includes: a door body and a refrigeration compartment. The door body is used to open or close the refrigeration compartment, and the refrigeration compartment is used to keep the items to be placed cold. The internal temperature of the refrigeration compartment is lower than the air temperature in the external environment. When the door body of the refrigeration equipment is opened or closed, the air convection speed between the air inside the refrigeration compartment and the air in the air increases, and the higher temperature gas in the air will enter the refrigeration compartment. After the refrigeration equipment is closed, when the water vapor in the air hits the inner wall of the refrigeration equipment, heat transfer from the water vapor to the inner wall of the refrigeration equipment will occur, the internal energy of the water vapor molecules will decrease, the movement speed of the water vapor molecules will slow down, and the water vapor will change from gas to liquid water. The liquefied liquid water will adhere to the surface of the inner wall of the refrigeration equipment. When the liquid water reaches a certain volume, it will slide along the inner wall of the refrigeration equipment under the action of gravity.

[0050] In addition, the refrigeration equipment also includes: a guide pipe and a water receiving pan. One end of the guide pipe is connected to the refrigeration compartment, and the other end of the guide pipe is connected to the water receiving pan. The liquid water in the refrigeration compartment will drip into the water receiving pan after being guided by the guide pipe. The water receiving pan is used to receive the dripping water.

[0051] The amount of water in the water tray will gradually increase. Therefore, during the design of the refrigeration equipment, part of the connecting pipe between the compressor and the condenser will be placed in the water tray. The high-temperature and high-pressure refrigerant gas delivered by the compressor will pass through the connecting pipe and transfer part of the heat to the water tray in the form of heat conduction, thereby causing the temperature inside the water tray to increase, causing the water in the water tray to evaporate.

[0052] However, the evaporation efficiency of water in the water tray of the conventional refrigeration equipment is low, so there is a risk of overflow of the water tray. In addition, the energy saving performance of the refrigerator is also poor.

[0053] Based on this, the embodiment of the present application provides a refrigeration device. The refrigeration device provided by the embodiment of the present application sets a connecting channel between the first water receiving tray and the second water receiving tray, so that when the liquid level in the first water receiving tray is higher than the connecting channel (hereinafter referred to as the high liquid level), the condensed water in the first water receiving chamber flows into the second water receiving tray through the connecting channel. At the same time, the embodiment of the present application sets a heating component to heat the condensed water passing through the connecting channel to improve the evaporation efficiency of the condensed water when the first water receiving tray is at the high liquid level, thereby reducing the risk of overflow of the first water receiving tray and the second water receiving tray. The structural features and operating mechanism of the refrigeration device in the present application will be described in detail below in conjunction with the drawings of the specification.

[0054] Figure 1 The box structure diagram of the refrigeration equipment provided in the embodiment of the present application is shown. Figure 1 The refrigeration device 1 includes a box body 10. The box body 1 defines a receiving cavity 11 and a refrigeration compartment 12 that are spaced apart. In the height direction of the box body 1, the receiving cavity 11 is arranged below the refrigeration compartment 12. The refrigeration compartment 12 is used to refrigerate or freeze items, and the receiving cavity 11 is used to install other components (e.g., condenser, compressor, etc.) in the refrigeration device 1.

[0055] In addition, the box body 10 is also provided with an opening communicating with the refrigerating compartment 12 , so that a user can place an item in the refrigerating compartment 12 or take an item out of the refrigerating compartment 12 through the opening.

[0056] Exemplarily, the refrigeration compartment 12 can be a refrigerator, a temperature-changing room or a freezer. The temperature of a refrigerator is generally between 2°C and 8°C, which can keep food in a refrigerated state; the temperature of a freezer is generally between -14°C and -26°C, which can keep food in a frozen state; the temperature of a temperature-changing room is generally adjustable between 5°C and -7°C, or can be directly adjusted to -18°C for use as a freezer.

[0057] Figure 2 The internal structure diagram of the accommodating chamber of the refrigeration device provided in the embodiment of the present application is shown. Figure 2 The refrigeration device 1 may further include: a condenser 13, a compressor 14, an evaporation tube 15, a guide tube 16 and a water receiving tray 20, and the condenser 13, the compressor 14, the evaporation tube 15, the guide tube 16 and the water receiving tray 20 are all arranged in the accommodating chamber 11.

[0058] Among them, one end of the evaporation tube 15 can be connected to the exhaust port of the compressor 14, and the other end is connected to the air inlet of the condenser 13. It can be understood that during the operation of the compressor 14, high-temperature and high-pressure refrigerant gas is generated and transported to the condenser 13. When the evaporation tube 15 transports the high-temperature and high-pressure refrigerant gas, the surface temperature of the high-temperature and high-pressure refrigerant gas is higher than the surface temperature of the evaporation tube 15. Therefore, heat conduction occurs between the high-temperature and high-pressure refrigerant gas and the evaporation tube 15, so that the surface temperature of the evaporation tube 15 increases.

[0059] Figure 3 One of the structural schematic diagrams of the water receiving tray of the refrigeration equipment provided in the embodiment of the present application is shown, and the Figure 2 and Figure 3 The water receiving tray 20 may include a first water receiving tray 21 , a second water receiving tray 22 and a heating assembly 23 .

[0060] Among them, a first water receiving chamber 210 is formed in the first water receiving tray 21, one end of the guide tube 16 is connected to the first water receiving chamber 210, and the other end of the guide tube 16 is connected to the refrigeration chamber 12, so that the condensed water generated by the refrigeration chamber 12 can be gathered in the first water receiving chamber 210 through the guide tube 16.

[0061] In addition, a second water receiving chamber 220 is formed in the second water receiving pan 22, and at least a portion of the evaporation tube 15 is located in the first water receiving chamber 210, and / or at least a portion of the evaporation tube 15 is located in the second water receiving chamber 220. A communication channel is formed between the first water receiving pan 21 and the second water receiving pan 22 to communicate with the first water receiving pan 21 and the second water receiving pan 22, so that the fluid in the first water receiving chamber 210 can flow into the second water receiving chamber 220.

[0062] Exemplarily, at least a portion of the evaporation tube 15 is located in the first water receiving chamber 210, so that the condensed water and other waste water introduced into the first water receiving chamber 210 by the guide tube 16 can be immediately heated by the evaporation tube 15, so that the fluid in the first water receiving tray 21 evaporates in time, thereby improving the evaporation efficiency of the water receiving tray 20.

[0063] Exemplarily, at least part of the evaporation tube 15 is located in the second water receiving chamber 220. Since the condensed water and other waste water will mix with the dirt in the refrigeration chamber 12 when flowing from the refrigeration chamber 12 to the guide pipe 16, the mixed water will be guided by the guide pipe 16 and then drip to the first water receiving pan 21. The first water receiving pan 21 will adhere to dust in the air during use. After the water in the first water receiving pan 21 evaporates, the dust in the air will mix with the dirt in the refrigeration device 1 to form a viscous substance, which will corrode the evaporation tube 15. Therefore, by locating at least part of the evaporation tube 15 in the second water receiving chamber 220, the waste water discharged from the refrigeration chamber 12 can be precipitated in the first water receiving chamber 210, and the corrosive substances will accumulate at the bottom of the first water receiving pan 21. The relatively clean waste water will flow through the connecting channel into the second water receiving chamber 220 and be heated and evaporated by the evaporation tube 15 in the second water receiving chamber 220.

[0064] It can be understood that since the water receiving tray 20 of the present application also includes a heating component 23 that can heat the connecting channel, condensed water and other waste water can continuously absorb the heat of the heating component 23 and gradually increase the temperature during the process of flowing from the first water receiving chamber 210 through the connecting channel into the second water receiving chamber 220, so that they can evaporate faster after entering the second water receiving chamber 220.

[0065] It should be noted that a first scale can be set on the inner wall surface of the first water receiving tray 21, and the height of the connecting channel can be set at the first scale. In this way, when the liquid level in the first water receiving chamber 210 reaches the first scale position, the liquid can flow from the first water receiving chamber 210 through the connecting channel into the second water receiving chamber 220, so that the liquid levels of condensed water and waste water in the first water receiving chamber 210 and the second water receiving chamber 220 are close.

[0066] There are many possible structural designs for the specific structural form of the heating component 23 and its position in the overall structure of the water receiving tray 20. The beneficial effects of different design structures are described in detail below.

[0067] Continue reading Figure 3 In some embodiments, the heating component 23 includes a heating tube 231, one end of the heating tube 231 is connected to the first water receiving chamber 210, and the other end of the heating tube 231 is connected to the second water receiving chamber 220. A connecting channel is formed in the heating tube 231, and the heating tube 231 is thermally connected to the condenser 13 so that the condenser 13 provides heat energy for the heating tube 231.

[0068] It should be noted that the heat conduction here includes different forms such as heat conduction, heat convection and heat radiation. Therefore, the specific position of the heating tube 231 in the present application also has a variety of possible settings.

[0069] Continue reading Figure 3 In a possible structural design, the condenser 13 includes a heat exchange coil 131 and a plurality of fins 132 , the plurality of fins 132 are arranged on the heat exchange coil 131 at intervals, and the heating tube 231 is in contact with the plurality of fins 132 .

[0070] It can be understood that the above structural arrangement divides the heat exchange between the refrigerant and the condensed water and the waste water into two stages:

[0071] In the first stage, the high-temperature and high-pressure refrigerant flowing out of the compressor 14 first enters the heat exchange coil 131 of the condenser 13 through the evaporator tube 15, and the high-temperature refrigerant transfers heat to the evaporator tube 15. After the evaporator tube 15 is heated, it heats the condensed water and waste water in the first water receiving chamber 210. At the same time, the condensed water and waste water assist in cooling the high-temperature refrigerant in the evaporator tube 15.

[0072] In the second stage, the refrigerant in a high-temperature and high-pressure state dissipates heat through the fins 132 while flowing through the heat exchange coil 131, and conducts the heat to the multiple fins 132. Since the heating tube 231 is in contact with the multiple fins 132, when the liquid level of the condensed water and waste water in the first water receiving chamber 210 reaches the first scale position of the first water receiving tray 21, the condensed water and waste water can be secondary heated by the heat of the high-temperature refrigerant in the heat exchange coil 131 while flowing through the heating tube 231. Similarly, the condensed water and waste water secondary cool the high-temperature refrigerant in the evaporator tube 15.

[0073] In this way, the condensed water and waste water can be fully heat exchanged with the refrigerant through the above two stages, and the two complement each other, and the temperature of the condensed water and waste water can be increased, which is more conducive to improving the evaporation efficiency of the condensed water and waste water. At the same time, the temperature of the refrigerant can be reduced, which is conducive to reducing the power consumption of the condenser 13.

[0074] Figure 4 The schematic diagram of the position relationship between the heating tube and the condenser is shown in conjunction with Figure 3 and Figure 4 A connection portion 133 that matches the circumferential wall surface of the heating tube 231 is formed on the plurality of fins 132 , and the circumferential wall surface of the heating tube 231 is in surface contact with the connection portion 133 .

[0075] It can be understood that the larger the contact area between the heating tube 231 and the fin 132, the more heat is exchanged between the heating tube 231 and the heat exchange coil 131 through heat conduction and the higher the heat exchange efficiency. Therefore, when the connecting portion 133 formed by multiple fins 132 is arranged in a surface contact form with the circumferential wall surface of the heating tube 231, the heat exchange efficiency between the heating tube 231 and the heat exchange coil 131 can be improved.

[0076] Figure 5The second structural schematic diagram of the water receiving tray of the refrigeration equipment provided in the embodiment of the present application is shown. Figure 5 In another possible structural design, the condenser 13 may also include a fan 134 , the heat exchange coil 131 and the plurality of fins 132 are located on the air inlet side 135 of the fan 134 , and the heating tube 231 is located on the air outlet side 136 of the fan 134 .

[0077] That is to say, in another possible structural design, the heating tube 231 can also be set at the air outlet side 136 of the fan 134. In this way, on the one hand, there is no longer any obstruction on the air inlet side 135 of the fan 134, and the air inlet area of ​​the fan 134 is increased, so that the heat dissipation effect of the condenser 13 on the refrigerant is enhanced, and the high-temperature and high-pressure refrigerant is promoted to be converted into a high-pressure and low-temperature refrigerant; on the other hand, the airflow on the air inlet side 135 performs convective heat exchange when flowing through the heat exchange coil 131 and the fins 132. After absorbing heat, the airflow flows out from the air outlet side 136. The heated airflow blows to the heating tube 231 located on the air outlet side 136, and then transfers the heat to the condensed water and wastewater in the heating tube 231 through the thermal convection effect, thereby achieving the purpose of heating the condensed water and wastewater in the connecting channel.

[0078] Furthermore, the first water receiving pan 21 and the second water receiving pan 22 can be respectively arranged on opposite sides of the condenser 13, and the heating pipe 231 and the condenser 13 are arranged parallel to each other between the first water receiving pan 21 and the second water receiving pan 22. In this way, the heating pipe 231 is arranged opposite to the heat exchange coil 131 and the fin 132 in the condenser 13, and the high-temperature heat exchange coil 131 and the fin 132 can also provide heat to the low-temperature heating pipe 231 through the thermal radiation effect, thereby further improving the heating effect of the condensed water and waste water in the communication channel.

[0079] It should be noted that the first water receiving tray 21 and the second water receiving tray 22 can be designed as a symmetrical structure and disposed on both sides of the condenser 13, so as to reduce the size of the mold and reduce the mold investment.

[0080] Figure 6 The third structural diagram of the water receiving tray of the refrigeration equipment provided in the embodiment of the present application is shown. Figure 6 In other embodiments, the evaporator tube 15 includes a first evaporator tube 151 and a second evaporator tube 152, one end of the first evaporator tube 151 is connected to the compressor 14, and one end of the second evaporator tube 152 is connected to the condenser 13. The heating component 23 also includes a heat exchange tube 232, which is arranged in the connecting channel, one end of the heat exchange tube 232 is connected to the other end of the first evaporator tube 151, and the other end of the heat exchange tube 232 is connected to the other end of the second evaporator tube 152.

[0081] That is to say, the evaporation tube 15 in the first water receiving tray 21 can be extended and set in the connecting channel as a heat exchange tube 232. The high-temperature and high-pressure refrigerant in the evaporation tube 15 provides heat for the condensed water and other waste water flowing through the connecting channel, thereby accelerating the evaporation efficiency of the condensed water and other waste water.

[0082] Figure 7 The structural diagram of the connecting slot of the refrigeration equipment provided in the embodiment of the present application is shown in combination with Figure 6 and Figure 7 In some embodiments of the present application, the heating component 23 also includes a connecting groove 233, which connects the first water receiving chamber 210 and the second water receiving chamber 220, and a connecting channel is formed in the connecting groove 233. The condenser 13 includes a fan 134, and the connecting groove 233 is arranged on the air inlet side 135 of the fan 134.

[0083] It is understandable that using the connecting groove 233 to form a connecting channel and arranging it at the air inlet side 135 of the fan 134 can bring two advantages:

[0084] On the one hand, when the water level in the first water receiving pan 21 is low, for example, the height of the connecting groove 233 and the first water receiving pan 21 at the connecting position is the second scale of the first water receiving pan 21, and the water level in the first water receiving pan 21 is lower than the second scale, the first evaporation tube 151 and the second evaporation tube 152 located in the first water receiving pan 21 heat the condensed water and other waste water, and the heat exchange tube 232 located in the connecting groove 233 is in an exposed state because the waste water has not flowed through the connecting groove 233. Therefore, when the fan 134 is started, the relatively low temperature airflow on the air inlet side 135 can perform forced convection heat exchange with the high temperature and high pressure refrigerant in the heat exchange tube 232, thereby assisting the condenser 13 in dissipating the heat of the refrigerant, achieving an energy-saving effect;

[0085] On the other hand, when the water level in the first water receiving tray 21 is higher than the second scale, the heat exchange tube 232 located in the connecting groove 233 is in an immersed state due to the wastewater flowing through the connecting groove 233, and the high-temperature and high-pressure refrigerant in the heat exchange tube 232 transfers heat to the wastewater through the heat exchange tube 232, thereby accelerating the evaporation efficiency of the wastewater.

[0086] That is to say, when the condensed water and other waste water in the first water receiving pan 21 accumulate less, and the evaporation efficiency can be satisfied by using only the first evaporation tube 151 and the second evaporation tube 152 in the first water receiving pan 21, the connecting groove 233 plays the role of using the low-temperature airflow on the air inlet side 135 to cool the high-temperature refrigerant in the heat exchange tube 232, thereby achieving energy saving. When the condensed water and other waste water in the first water receiving pan 21 accumulate more, and the evaporation efficiency cannot be satisfied by using only the first evaporation tube 151 and the second evaporation tube 152 in the first water receiving pan 21, the connecting groove 233 plays the role of using the high-temperature refrigerant in the heat exchange tube 232 to heat the condensed water and other waste water flowing through the connecting groove 233, thereby achieving the role of accelerating the evaporation efficiency.

[0087] In this way, the connecting groove 233 and the heat exchange tube 232 thereon play different roles according to the different liquid level positions in the first water receiving tray 21, thereby achieving energy saving as much as possible while ensuring that the evaporation efficiency meets the use requirements.

[0088] Figure 8 The fourth structural schematic diagram of the water receiving tray of the refrigeration equipment provided in the embodiment of the present application is shown. Fig. 9 The scale diagram in the first water receiving tray is shown. Figure 8 and Fig. 9 The structure of the water receiving tray 20 may include a connecting groove 233 and a heat exchange tube 232, and may also include a heating tube 231 inserted into the condenser 13. In the first water receiving tray 21, the second scale is higher than the first scale (i.e., the height of the connection position between the heat exchange tube 232 and the first water receiving chamber 210 is greater than the height of the connection position between the heating tube 231 and the first water receiving chamber 210).

[0089] It can be understood that when the liquid level of the condensed water and other waste water accumulated in the first water receiving chamber 210 is below the first scale, it means that there is very little condensed water and other waste water at this time, and the condensed water and other waste water only need to be heated and evaporated by the first evaporation tube 151 and the second evaporation tube 152 arranged at the bottom of the first water receiving chamber 210.

[0090] When the liquid level of the condensed water and other waste water accumulated in the first water receiving chamber 210 is higher than the first scale and lower than the second scale, it means that there is a lot of condensed water and other waste water at this time, and a part of the waste water in the first water receiving chamber 210 needs to be diverted to the second water receiving chamber 220 through the heating tube 231. During this process, the low-temperature waste water in the heating tube 231 exchanges heat with the high-temperature refrigerant in the heat exchange coil 131 through the fins 132, so that it has a higher temperature after entering the second water receiving chamber 220, thereby accelerating the evaporation efficiency.

[0091] When the liquid level of condensed water and other waste water accumulated in the first water receiving chamber 210 is higher than the second scale, it means that there is too much condensed water and other waste water, and there is a risk of overflow in the first water receiving tray 21. At this time, the connecting groove 233 can be used to assist the heating tube 231 for diversion. In this process, the high-temperature refrigerant in the heat exchange tube 232 provides heat for the low-temperature waste water flowing through the connecting groove 233, so that it has a higher temperature after entering the second water receiving chamber 220, thereby further accelerating the evaporation efficiency.

[0092] Thus, through the above scheme, the water receiving tray 20 of the refrigeration equipment 1 provided in the present application can automatically adjust its evaporation efficiency according to the different liquid level heights of the wastewater accumulated in the water receiving tray 20, thereby reducing the overflow risk of the water receiving tray 20.

[0093] Fig.10 A schematic diagram showing the position of the overflow pipe of the refrigeration equipment provided in the embodiment of the present application is shown. Fig.10 In some embodiments of the present application, a drain outlet is provided on the bottom wall of the first water receiving tray 21, and the water receiving tray 20 also includes an overflow pipe 24, one end of the overflow pipe 24 is connected to the drain outlet, and the height of the other end of the overflow pipe 24 is higher than the first connection position, and the first connection position is the connection position between the connecting channel and the first water receiving tray 21.

[0094] It can be understood that in order to ensure that the first water receiving tray 21 does not cause damage to other parts of the refrigeration equipment 1 due to overflow, a drain outlet can be set on the bottom wall of the first water receiving tray 21, and the end of the overflow pipe 24 away from the drain outlet will guide the condensed water and other waste water above the second scale through the overflow pipe 24 to the drain outlet, and then be discharged to the external environment from the drain outlet.

[0095] Fig.11 FIG. 1 shows one of the structural schematic diagrams of the compressor mounting plate of the refrigeration equipment provided in the embodiment of the present application, referring to FIG. Fig.11 In some embodiments of the present application, the refrigeration device 1 also includes a compressor mounting plate 30, the compressor mounting plate 30 includes a support portion 31 and a wind shield portion 32, the support portion 31 is connected to the compressor 14, the wind shield portion 32 is connected to the support portion 31, and is located on the side of the support portion 31 away from the air inlet side 135.

[0096] It is understandable that when the cabinet 10 is placed against a wall, the hot air from the compressor 14 will bounce back through the wall to the air inlet side 135 of the condenser 13, causing the rebounded hot air flow to be sucked back into the condenser 13, thereby resulting in a poor heat exchange effect of the condenser 13. Therefore, the present application provides a wind shield 32 to block the hot air flow outside the air inlet side 135, thereby preventing the rebounded hot air flow from being sucked into the condenser 13, thereby ensuring the cooling effect of the condenser 13.

[0097] Fig.12The second structural schematic diagram of the compressor mounting plate of the refrigeration equipment provided in the embodiment of the present application is shown. Fig.12 In some embodiments of the present application, a dustproof net 33 is provided on the compressor mounting plate 30, so as to prevent the refrigeration equipment 1 from sucking in dust or foreign objects to block the condenser 13 during operation.

[0098] Fig.13 Shows Fig.12 Schematic diagram of the enlarged structure at position A, see Fig.13 The water receiving tray also includes a fastening pipe 25, which includes a connecting pipe 251, an abutting pipe 252 and a fastening groove 253. One end of the connecting pipe 251 is connected to the side wall of the first connecting tray 21, and the other end of the connecting pipe 251 is connected to the abutting pipe 252. Both ends of the abutting pipe 252 are respectively connected to the connecting pipe 252, and the middle part of the abutting pipe 252 is connected to the fastening groove 253 provided on the bottom wall of the first connecting tray 21, so that the abutting pipe 252 can be pressed against the evaporation tube 15. In this way, the force generated by the refrigerant in the evaporation tube 20 when it flows rapidly to drive the evaporation tube 20 to move can be effectively constrained, so that the evaporation tube 20 can be stably limited at the bottom of the first connecting tray 21, thereby heating the condensed water and other waste water in the first connecting tray 21.

[0099] In another possible structural design, a limiting groove 254 may be further provided on the bottom wall of the first connecting plate 21 , and the evaporation tube 15 may be directly engaged in the limiting groove 254 , thereby also stabilizing the evaporation tube 15 .

[0100] Fig.14 The schematic diagram of the structure of the drainage pipe of the refrigeration equipment provided in the embodiment of the present application is shown. Fig.15 The fifth structural schematic diagram of the water receiving tray of the refrigeration equipment provided in the embodiment of the present application is shown. Fig.16 Show Fig.15 The enlarged view of the local details at position B, combined with reference Fig.14 , Fig.15 and Fig.16 The refrigeration equipment 1 also includes a drainage pipe 40 and a top cover 50.

[0101] The top cover 50 is used to connect the box body 10 (such as Figure 1 As shown in the figure, the accommodating chamber 11 and the refrigerating chamber 12 are separated, and the first top cover 51 and the second top cover 52 are included. The heights of the first top cover 51 and the second top cover 52 are different. In this way, the refrigerating chamber 12 located above the accommodating chamber 11 also has different heights, so as to facilitate the display of different commodities and facilitate customers to observe and purchase the commodities.

[0102] The guide pipe 16 is provided through the first top cover 51, and the condensed water and other waste water in the refrigeration room 12 located above the first top cover 51 are directly introduced into the first water receiving pan 21. The drainage pipe 40 is provided through the second top cover 52, and the condensed water and other waste water in the refrigeration room 12 located above the second top cover 52 are first introduced into the connecting groove 233, and then drained into the first water receiving pan 21 or the second water receiving pan 22 through the drainage channel 234 provided in the connecting groove 233. In this way, the condensed water and other waste water generated in different areas of the refrigeration room 12 can be respectively diverted through different pipes, so as to facilitate the timely removal of waste water in the refrigeration room 12.

[0103] In summary, the refrigeration equipment provided by the present application includes at least the following advantages:

[0104] (1) The water tray can automatically adjust its evaporation efficiency according to the different liquid levels of the wastewater accumulated in the water tray, thereby reducing the risk of overflow of the water tray;

[0105] (2) The connecting groove and the heat exchange tube thereon can play different roles according to the different liquid level positions in the first water receiving tray, thereby achieving energy saving as much as possible while ensuring that the evaporation efficiency meets the use requirements.

[0106] (3) The wind shield blocks the hot air flow outside the air inlet side, thereby preventing the rebounded hot air flow from being sucked into the condenser, thereby ensuring the cooling effect of the condenser.
