[0037] Exemplarily, the refrigeration device 100 is applied in the drinking water equipment 1000 for refrigeration of drinking water; specifically, the water inlet end of the cold tank assembly 20 is provided with a water inlet flow path, the water outlet end of the cold tank assembly 20 is provided with a water outlet flow path, the water flows through the water inlet flow path, the cold tank assembly 20 and the water outlet flow path in sequence, the refrigeration assembly 30 refrigerates the water flowing through the cold tank assembly 20, and cold water is discharged from the drinking water equipment 1000; during the foregoing working process, because the temperature of the cold tank assembly 20 is relatively low, condensate water is generated on the outer surface of the cold tank assembly 20, the mounting bracket 10 guides the condensate water to flow into the water collecting groove 111, so that the condensate water is collected, the condensate water is prevented from flowing to other positions of the refrigeration device 100 or the drinking water equipment 1000, and the normal operation of the drinking water equipment 1000 is affected, and then the condensate water in the water collecting groove 111 is heated and evaporated by the heating unit.

[0038] In addition, the heating unit, the cold tank assembly 20 and the refrigeration assembly 30 can all be arranged on the mounting bracket 10, and then the refrigeration device 100 is integrally arranged in the drinking water equipment 1000 through the mounting bracket 10, so that the integration and assembly efficiency of the drinking water equipment 1000 are improved.

[0039] Therefore, according to the refrigeration device 100 for the drinking water equipment 1000 provided in the embodiment of the present application, the condensate water generated inside the device can be collected by the water collecting groove 111, and the condensate water in the water collecting groove 111 is evaporated by the heating unit, so that the condensate water is prevented from overflowing or leaking inside the device, and the normal operation of the refrigeration device 100 is affected.

[0041] More specifically, the water in the cold tank assembly 20 can be refrigerated by a refrigerant circulation loop, and the high-temperature part in the refrigerant circulation loop can be configured as a heating unit to heat the water in the water collecting groove 111, so that the purposes of reducing cost and saving energy can be achieved. The present application provides the following embodiments for illustration:

The heating unit can comprise a first refrigerant pipe between the compressor 33 and the condenser 31, and / or a second refrigerant pipe between the condenser 31 and the throttling element 34. In this way, when the refrigeration device 100 is working, the refrigerant circulation loop is in a refrigeration mode, and the refrigerant circulates between the compressor 33, the condenser 31, the throttling element 34 and the evaporator 32. The refrigerant flowing through the first refrigerant pipe and the second refrigerant pipe has a higher temperature, and releases heat through the first refrigerant pipe and the second refrigerant pipe. In this way, the heat released through the first refrigerant pipe and / or the second refrigerant pipe can heat the condensed water in the water collecting tank 111, thereby improving energy utilization and saving costs.

[0044] Embodiment 2

[0045] As Figures 2 to 4 The heating unit comprises the condenser 31, and the refrigeration assembly 30 comprises the evaporator 32, the compressor 33 and the throttling element 34. The condenser 31 and the compressor 33 are arranged on the mounting bracket 10, and the evaporator 32 is arranged in the cold tank assembly 20. The condenser 31, the throttling element 34, the evaporator 32 and the compressor 33 are connected in sequence to form a refrigerant circulation loop. In this way, when the refrigeration device 100 is working, the refrigerant circulation loop is in a refrigeration mode, and the refrigerant circulates between the compressor 33, the condenser 31, the throttling element 34 and the evaporator 32. The refrigerant flowing through the condenser 31 has a higher temperature, and releases heat through the condenser 31. In this way, the heat released through the condenser 31 can heat the condensed water in the water collecting tank 111, thereby improving energy utilization and saving costs. In addition, the throttling element 34 can be mounted on the mounting bracket 10 or on the refrigerant pipe in the refrigerant circulation loop.

[0046] Further, the condenser 31 comprises a condenser pipe group 311, an inlet header 312 and an outlet header 313. The condenser pipe group 311 is connected between the inlet header 312 and the outlet header 313. The condenser pipe group 311, the inlet header 312 and / or the outlet header 313 are configured as the heating unit and are distributed opposite to the water collecting tank 111. In this way, the evaporation efficiency of the condensed water can be improved, and overflow or leakage of the condensed water can be avoided.

[0047] It can be understood that the condenser tube group 311 comprises a plurality of condenser tubes, the inlet manifold 312 is connected to the inlet ends of the plurality of condenser tubes, and the outlet manifold 313 is connected to the outlet ends of the plurality of condenser tubes; when the high-temperature refrigerant flows through the condenser 31, the high-temperature refrigerant first passes through the inlet manifold 312, the inlet manifold 312 collects a large amount of high-temperature refrigerant, and distributes the high-temperature refrigerant into the plurality of condenser tubes to improve the heat exchange efficiency of the condenser 31, and then the refrigerant in the plurality of condenser tubes is re-collected in the outlet manifold 313, and is discharged from the condenser 31, therefore, the inlet manifold 312 and the outlet manifold 313 of the condenser 31 are relatively concentrated in refrigerant and have a high temperature, and the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 can be configured as a heating unit, so that the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 heat the condensed water in the water collecting tank 111, and the evaporation efficiency of the condensed water is improved, and overflow or leakage of the condensed water is avoided.

[0048] In addition, the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 configured as a heating unit can be distributed relative to the water collecting tank 111, so that the heat of the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 is better transmitted to the water collecting tank 111, and the evaporation efficiency of the condensed water is further improved.

[0049] In addition, in some specific examples, the condenser 31 can be a micro-channel condenser 31.

[0050] As Figures 1 to 4 In some embodiments of the present application, the mounting bracket 10 comprises a mounting plate 11, the condenser tube group 311 is mounted on the mounting plate 11, and the water collecting tank 111 is arranged on the mounting plate 11; in this way, the heat emitted by the condenser tube group 311 mounted on the mounting plate 11 can evaporate the condensed water in the water collecting tank 111.

[0051] Optionally, the condenser tube group 311 is arranged in the water collecting tank 111, so that the condenser tube group 311 evaporates the condensed water in the water collecting tank 111. Optionally, the condenser tube group 311 is arranged above the water collecting tank 111, and the condenser tube group 311 can be configured as a heat source above the water collecting tank 111 to heat the condensed water in the water collecting tank 111 by indirect heating.

[0052] Further, at least a portion of the water collecting tank is opposite to the inlet manifold in the up-down direction, and the lower end of the inlet manifold extends into the water collecting tank; and / or at least a portion of the water collecting tank is opposite to the outlet manifold in the up-down direction, and the lower end of the outlet manifold extends into the water collecting tank; in this way, the water collecting tank 111 can be used for mounting the condenser 31, and the condensed water is evaporated by the heat emitted by the condenser 31.

[0053] Specifically, the mounting plate 11 is provided with a water collecting groove 111, and the inlet header pipe 312 and the outlet header pipe 313 of the condenser 31 can respectively extend into the water collecting groove 111 to realize the mounting of the condenser 31 on the mounting plate 11, and the condenser pipe group 311 is mounted on the mounting plate 11, and the mounting plate 11 is provided with a heat dissipation through hole 112 opposite to the condenser pipe group 311, so as to facilitate the air cooling heat dissipation of the refrigerant in the condenser pipe group 311.

[0054] In addition, in some examples, the water collecting groove 111 includes a first water collecting groove and a second water collecting groove, the first water collecting groove and the second water collecting groove are arranged in a spaced manner, the inlet header pipe 312 extends into the first water collecting groove, and the outlet header pipe 313 extends into the second water collecting groove, so as to realize the assembly of the condenser 31 on the mounting plate 11. In other examples, the water collecting groove 111 extends from the inlet header pipe 312 to the outlet header pipe 313 and has a first inner side wall and a second inner side wall in the extending direction, the inlet header pipe 312 and the outlet header pipe 313 respectively extend into the water collecting groove 111, and the inlet header pipe 312 is limited by the first inner side wall of the water collecting groove 111, and the outlet header pipe 313 is limited by the second inner side wall of the water collecting groove 111, so as to realize the mounting limiting of the condenser 31 on the mounting plate 11.

[0055] As Figure 1 , Figure 2 and Figure 3 , in some embodiments of the present application, the mounting bracket 10 includes a mounting plate 11 and a support frame 12, the support frame 12 is connected to the mounting plate 11 and is arranged above the mounting plate 11, and the cold tank assembly 20 is arranged on the support frame 12; in detail, the condensate water generated on the outer surface of the cold tank assembly 20 flows to the water collecting groove 111 of the mounting plate 11 under the action of gravity and the flow guiding action of the support frame 12, so as to realize the collection of the condensate water and avoid the overflow or leakage of the condensate water.

[0056] More specifically, the support frame 12 has a mounting surface, the cold tank assembly 20 is arranged on the mounting surface, and at least a portion of the mounting surface is arranged in a downward inclined manner, so as to guide the condensate water generated by the cold tank assembly 20 towards the water collecting groove; in this way, the condensate water generated by the cold tank assembly 20 can flow to the support frame 12 and flow to the water collecting groove 111 of the mounting plate 11 under the flow guiding action of the support frame 12, so as to improve the collection efficiency of the condensate water.

[0057] In some specific examples, the support frame 12 extends in the up-down direction, the lower part of the support frame 12 is arranged on the mounting plate 11, and the cold tank assembly 20 is arranged on the upper part of the support frame 12; in this way, the cold tank assembly 20 can be arranged higher than the mounting plate 11 and has a space between the cold tank assembly 20 and the mounting plate 11, so as to facilitate the condensate water generated on the outer surface of the cold tank assembly 20 to drop into the water collecting groove 111 of the mounting plate 11 under the action of gravity, and improve the collection efficiency of the condensate water.

[0058] As Figure 1 , Figure 2 and Figure 3 In some embodiments of the present application, the support frame 12 comprises a first side plate 121, a second side plate 122 and a top plate 123, the top surface of the top plate 123 is provided as the aforementioned mounting surface, the first side plate 121 and the second side plate 122 both extend in the up-down direction, the lower part of the first side plate 121 and the lower part of the second side plate 122 are respectively connected to the mounting bracket 11, the upper part of the first side plate 121 and the upper part of the second side plate 122 are respectively connected to the top plate 123, and the top plate 123 is connected to the cold tank assembly 20. In this way, the connection area of the support frame 12 and the cold tank assembly 20 can be increased, thereby improving the connection strength of the support frame 12 and the cold tank assembly 20, and ensuring the working stability of the refrigeration device 100.

[0059] In addition, in some specific examples, the first side plate 121, the second side plate 122 and the top plate 123 surround the mounting space, and the compressor 33, the condenser 31 and the throttling element 34 can be arranged in the mounting space. In this way, the cold tank assembly 20 is located above the top plate 123, and the compressor 33, the condenser 31 and the throttling element 34 are located below the top plate 123. The aforementioned multiple devices are arranged compactly in the up-down direction, which can improve the space utilization of the refrigeration device 100, and the top plate 123 can shield at least part of the structure of the compressor 33, the condenser 31 and the throttling element 34, etc. to avoid the influence of condensate water droplets on the normal operation of the refrigeration device 100.

[0060] Further, the top plate 123 is inclined towards the water collecting groove 111 in a preset horizontal direction and a direction close to the water collecting groove 111. It can be understood that the top plate 123 has a third side edge and a fourth side edge opposite in the preset horizontal direction, the third side edge is closer to the water collecting groove 111 than the fourth side edge, and the top plate 123 is inclined towards the water collecting groove 111 in a direction from the fourth side edge to the third side edge. In this way, the condensate water generated by the cold tank assembly 20 can flow to the top plate 123 and be collected at the third side edge under the flow guiding action of the top plate 123, and then flow into the water collecting groove 111 of the mounting bracket 11 to improve the collection efficiency of the condensate water.

[0061] As Figures 2 to 4The heating unit comprises a condenser 31, the refrigeration assembly 30 comprises an evaporator 32, a compressor 33 and a throttling element 34, and the condenser 31, the throttling element 34, the evaporator 32 and the compressor 33 are sequentially connected to form a refrigerant circulation loop; in this way, when the refrigeration device 100 is working, the refrigerant circulation loop is in a refrigeration mode, and the refrigerant circulates between the compressor 33, the condenser 31, the throttling element 34 and the evaporator 32, the temperature of the refrigerant flowing through the condenser 31 is relatively high, and the refrigerant releases heat through the condenser 31; in this way, the heat dissipated through the condenser 31 can heat the condensed water in the water collecting tank 111, so that the energy utilization rate is improved and the cost is saved.

[0062] In addition, the condenser 31 is arranged on the mounting bracket 10 and below the cold tank assembly 20; it can be understood that the condensed water generated on the outer surface of the cold tank assembly 30 can drip downward under the action of gravity, and therefore, the condenser 31 can be arranged below the cold tank assembly 20; in this way, the condensed water dripping from the cold tank assembly 30 can drip on the condenser 31, and the condensed water can be evaporated by means of the phase change and heat dissipation of the refrigerant in the condenser 31; and the arrangement of the condenser 31 and the cold tank assembly 20 is compact, and the space utilization rate is improved. Similarly, the compressor 33 is arranged on the mounting bracket 10 and below the cold tank assembly 20, so that the arrangement of the compressor and the cold tank assembly 20 is compact, and the space utilization rate is improved. In addition, the evaporator 32 is arranged in the cold tank assembly 20, so that the refrigeration effect of the cold tank assembly 20 is improved.

[0063] As Figure 1 , Figure 2 and Figure 3 In some embodiments of the present application, the outer bottom surface of the cold tank assembly 20 has a first side edge close to the water collecting tank 111 and a second side edge away from the water collecting tank 111, and the outer bottom surface of the cold tank assembly 20 is inclined toward the water collecting tank 111 in the direction from the second side edge to the first side edge; it can be understood that the water collecting tank 111 is located below the cold tank assembly 20, and the first side edge of the outer bottom surface of the cold tank assembly 20 is lower than the second side edge; the outer surface of the cold tank assembly 20 comprises an outer top surface, an outer peripheral surface and an outer bottom surface, and the condensed water generated on the outer top surface and the outer peripheral surface of the cold tank assembly 20 can flow to the outer bottom surface under the action of gravity and be collected at the first side edge of the outer bottom surface of the cold tank assembly 20 under the flow guiding action of the outer bottom surface of the cold tank assembly 20, and then flow into the water collecting tank 111 of the mounting bracket 11, so that the collection efficiency of the condensed water is further improved.

[0064] In order to facilitate the water collecting tank 111 to collect the condensed water, the water collecting tank 111 and the outer bottom surface of the cold tank assembly 20 can be arranged in various ways, and the present application provides the following embodiments for illustration:

[0065] Embodiment 1

[0066] As Figure 3The water collecting groove 111 includes a plurality of first side edges extending along the front-rear direction of the mounting plate 11, the plurality of water collecting grooves 111 are arranged in the front-rear direction at intervals, and in the projection in the up-down direction, the projection of the first side edge at least partially coincides with the projection of the water collecting groove 111. It can be understood that the arrangement direction of the plurality of water collecting grooves 111 is consistent with the extension direction of the first side edge of the outer bottom surface of the cold tank assembly 20, and the plurality of water collecting grooves 111 are opposite to the first side edge in the up-down direction. In this way, the condensed water flowing to the first side edge of the outer bottom surface of the cold tank assembly 20 can be more easily collected by the plurality of water collecting grooves 111, which facilitates the heating unit to evaporate the condensed water in the water collecting groove 111, and improves the working stability of the refrigeration device 100.

[0067] Of course, in combination with the foregoing, in actuality, the third side edge of the top plate 123 can also extend along the front-rear direction of the mounting plate 11, and in the projection in the up-down direction, the third side edge at least partially coincides with the projection of the water collecting groove 111, so that the condensed water flowing to the third side edge of the top plate 123 of the cold tank assembly 20 can be more easily collected by the plurality of water collecting grooves 111, which facilitates the heating unit to evaporate the condensed water in the water collecting groove 111, and improves the working stability of the refrigeration device 100.

[0068] Embodiment 2

[0069] The first side edge and the water collecting groove 111 extend along the front-rear direction of the mounting plate 11, and in the projection in the up-down direction, the projection of the first side edge at least partially coincides with the projection of the water collecting groove 111. It can be understood that the extension direction of the water collecting groove 111 is consistent with the extension direction of the first side edge of the outer bottom surface of the cold tank assembly 20, and the water collecting groove 111 is opposite to the first side edge in the up-down direction. In this way, the condensed water flowing to the first side edge of the outer bottom surface of the cold tank assembly 20 can be more easily collected by the water collecting groove 111, which facilitates the heating unit to evaporate the condensed water in the water collecting groove 111, and improves the working stability of the refrigeration device 100.

[0070] Similarly, the water collecting groove 111 and the top plate 123 can also be arranged in various ways, for example, the plurality of water collecting grooves 111 and the third side edge of the top plate 123 are opposite in the up-down direction, and the arrangement direction of the plurality of water collecting grooves 111 is consistent with the extension direction of the third side edge of the top plate 123; for another example, the water collecting groove 111 and the third side edge of the top plate 123 are opposite in the up-down direction, and the extension direction of the water collecting groove 111 is consistent with the extension direction of the third side edge of the top plate 123; the foregoing examples can facilitate the water collecting groove 111 to collect condensed water.

[0071] As Figure 2 and Figure 4In some embodiments of the present application, the refrigeration assembly 30 further comprises a heat dissipation fan 40, and the mounting bracket 10 is further provided with a heat dissipation through hole 112 opposite to the condenser 31, and the heat dissipation fan 40 is arranged at the heat dissipation through hole 112. The heat dissipation fan 40 accelerates the flow of air in the refrigeration device 100, improves the heat exchange efficiency of the condenser 31, and facilitates the refrigerant circulation loop to better cool the water in the cold tank assembly 20.

[0072] In addition, in order to prevent the condensed water in the water collecting groove 111 from flowing to the heat dissipation fan 40 through the heat dissipation through hole 112, causing the condensed water to splash everywhere, the periphery of the heat dissipation through hole 112 can be spaced apart from the water collecting groove 111 by a predetermined distance. Further, the mounting bracket 10 is further provided with a flange 113 extending in the up-down direction, the lower part of the flange 113 is connected to the periphery of the heat dissipation through hole 112, and the upper part of the flange 113 can support the condenser 31, thereby blocking the condensed water on the mounting bracket 11 and preventing the condensed water from flowing to the heat dissipation fan 40 through the heat dissipation through hole 112, and the condenser tank assembly is spaced apart from the heat dissipation fan 40 by a predetermined distance, thereby avoiding structural interference.

[0074] In some embodiments of the present application, the refrigeration device 100 further comprises a first water leakage protection switch arranged on the mounting bracket 10, which can be used to detect the water leakage of the refrigeration device 100. When the water flow in the refrigeration device 100 reaches a predetermined water level, the first water leakage protection switch is triggered and the water path of the refrigeration device 100 is cut off, thereby preventing the refrigeration device 100 from continuously leaking water.

[0075] In addition, the first water leakage protection switch and the water collecting groove 111 are respectively arranged on opposite sides of the mounting bracket 10 in the front-back direction; and / or the first water leakage protection switch and the water collecting groove 111 are respectively arranged on opposite sides of the mounting bracket 10 in the left-right direction; in this way, under the flow guiding effect of the outer bottom surface of the cold tank assembly 20 and the top plate 123 of the support frame 12, the condensed water generated on the outer surface of the cold tank assembly 20 can be guided away from the position of the first water leakage protection switch and into the water collecting groove 111, thereby preventing the condensed water generated by the cold tank assembly 20 from triggering the first water leakage protection switch and affecting the normal operation of the refrigeration device 100.

[0076] In some embodiments of the present application, the heating unit further comprises a heating pipe and / or a PTC heater. It can be understood that the heating unit can heat the condensed water in the water collecting groove 111 by electric heating, gas heating and the like, so as to evaporate the condensed water.

[0081] In addition, the top plate 123 of the support frame 12 has a third side edge close to the water collecting groove 111 and a fourth side edge away from the water collecting groove 111, and the top plate 123 is inclined towards the water collecting groove 111 in a direction from the fourth side edge to the third side edge, so that the condensed water flowing to the top plate 123 of the cold tank assembly 20 can be guided to the third side edge, and the third side edge is opposite to the water collecting groove 111 in the up-down direction, so that the condensed water of the third side edge can drip into the water collecting groove 111 under the action of gravity, thereby improving the condensed water collection efficiency of the water collecting groove 111.
