DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The present invention proposes a refrigeration device 100 for a drinking water device 1000, which can collect condensed water generated inside the device through a water collecting tank 111, and evaporate the condensed water in the water collecting tank 111 through a heating unit, thereby preventing the condensed water from overflowing or leaking inside the device and affecting the normal operation of the refrigeration device 100. In addition, a drinking water device 1000 is also proposed, and the drinking water device 1000 includes the above-mentioned refrigeration device 100.

[0035] like Figures 1 to 5 According to the refrigeration device 100 for a drinking water device 1000 according to an embodiment of the present invention, the refrigeration device 100 includes a mounting bracket 10, a heating unit, a cold tank assembly 20 and a refrigeration assembly 30.

[0036] Among them, the mounting bracket 10 is provided with a water collecting tank 111, the heating unit is arranged on the mounting bracket 10, and is used to heat the water in the water collecting tank 111, the cold tank assembly 20 is arranged on the mounting bracket 10, and the mounting bracket 10 is configured to guide the condensed water generated by the cold tank assembly 20 to flow to the water collecting tank 111, and the refrigeration assembly 30 is used to cool the water in the cold tank assembly 20; such an arrangement can prevent the condensed water from overflowing or leaking inside the device, affecting the normal operation of the refrigeration device 100.

[0037] Exemplarily, the refrigeration device 100 is used in the drinking water equipment 1000 for cooling drinking water; specifically, the water inlet end of the cold tank assembly 20 is provided with a water inlet flow path, and the water outlet end of the cold tank assembly 20 is provided with a water outlet flow path, and the water flows through the water inlet flow path, the cold tank assembly 20 and the water outlet flow path in sequence, and the refrigeration assembly 30 cools the water flowing through the cold tank assembly 20 to achieve cold water outlet of the drinking water equipment 1000; in the aforementioned working process, due to the low temperature of the cold tank assembly 20, condensed water is generated on the outer surface of the cold tank assembly 20, and the mounting bracket 10 guides the condensed water to flow into the water collecting tank 111, thereby collecting the condensed water to prevent the condensed water from flowing to other positions of the refrigeration device 100 or the drinking water equipment 1000, affecting the normal operation of the drinking water equipment 1000, and then the condensed water in the water collecting tank 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 set on the mounting bracket 10, and then the refrigeration device 100 is installed as a whole in the drinking water equipment 1000 through the mounting bracket 10, thereby improving the integration and assembly efficiency of the drinking water equipment 1000.

[0039] Therefore, according to the refrigeration device 100 for drinking water equipment 1000 according to the embodiment of the present invention, the condensed water generated inside the device can be collected through the water collecting tank 111, and the condensed water in the water collecting tank 111 can be evaporated by the heating unit to prevent the condensed water from overflowing or leaking inside the device and affecting the normal operation of the refrigeration device 100.

[0040] In some embodiments of the present invention, the heating unit is constructed to heat the water in the water collection tank 111 in a refrigerant-related manner; specifically, the heating unit has a refrigerant flow channel, which is suitable for high-temperature refrigerant to flow through; the heating unit can heat the condensed water in the water collection tank 111 by means of phase change and heat release of the refrigerant in the refrigerant flow channel; when the refrigeration device 100 is working, the high-temperature refrigerant flows through the refrigerant flow channel of the heating unit, and transfers heat to the water collection tank 111 through the heating unit, so that the condensed water in the water collection tank 111 is heated and evaporated to avoid overflow or leakage of the condensed water.

[0041] More specifically, the water in the cold tank assembly 20 can be cooled by a refrigerant circulation loop, and the high-temperature portion in the refrigerant circulation loop can be configured as a heating unit to heat the water in the water collection tank 111, thereby achieving the purpose of reducing costs and saving energy. The present invention provides the following embodiments for illustration:

[0042] Implementation Method 1

[0043] The refrigeration component 30 includes an evaporator 32, a compressor 33 and a throttling element 34. The condenser 31, the throttling element 34, the evaporator 32 and the compressor 33 are connected in series in sequence to form a refrigerant circulation loop. The heating unit may include 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 reflux 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 condensed water in the water collection tank 111 is heated by the heat emitted by the first refrigerant pipe and / or the second refrigerant pipe, which can improve energy utilization and save costs.

[0044] Implementation Method 2

[0045] like Figures 2 to 4 The heating unit includes a condenser 31, and the refrigeration assembly 30 includes an evaporator 32, a compressor 33, and a 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 condensed water in the water collection tank 111 is heated by the heat emitted by the condenser 31, which can improve energy utilization and save costs. In addition, the throttling element 34 can be installed on the mounting bracket 10, or on the refrigerant pipe in the refrigerant circulation loop.

[0046] Furthermore, the condenser 31 includes a condenser tube group 311, an inlet collecting pipe 312 and an outlet collecting pipe 313. The condenser tube group 311 is connected between the inlet collecting pipe 312 and the outlet collecting pipe 313. The condenser tube group 311, the inlet collecting pipe 312 and / or the outlet collecting pipe 313 are constructed as a heating unit and are distributed relative to the water collecting tank 111. Such an arrangement can improve the evaporation efficiency of the condensed water and avoid overflow or leakage of the condensed water.

[0047] It can be understood that the condenser pipe group 311 includes a plurality of condenser pipes, the inlet manifold 312 is connected to the inlet ends of the plurality of condenser pipes, and the outlet manifold 313 is connected to the outlet ends of the plurality of condenser pipes; when the high-temperature refrigerant flows through the condenser 31, it first passes through the inlet manifold 312, which gathers a large amount of high-temperature refrigerant and distributes the high-temperature refrigerant to the plurality of condenser pipes to improve the heat exchange efficiency of the condenser 31, and then the refrigerant in the plurality of condenser pipes is recirculated in the outlet manifold The refrigerant is gathered in 313 and discharged from the condenser 31. Therefore, the refrigerant in the inlet manifold 312 and the outlet manifold 313 of the condenser 31 is relatively concentrated and has a higher temperature. The condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 can be constructed as a heating unit. In this way, the condensed water in the water collecting tank 111 is heated by the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313, so as to improve the evaporation efficiency of the condensed water and avoid overflow or leakage of the condensed water.

[0048] In addition, the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 constructed as a heating unit can be distributed relative to the water collecting tank 111, so as to facilitate better transfer of heat from the condenser tube group 311, the inlet manifold 312 and / or the outlet manifold 313 to the water collecting tank 111, thereby further improving the evaporation efficiency of the condensed water.

[0049] Furthermore, in some specific examples, the condenser 31 may be a microchannel condenser 31 .

[0050] like Figures 1 to 4 In some embodiments of the present invention, the mounting bracket 10 includes a mounting tray 11, the condenser tube group 311 is mounted on the mounting tray 11, and the water collecting tank 111 is arranged on the mounting tray 11; in this way, the condensed water in the water collecting tank 111 can be evaporated by the heat dissipated by the condenser tube group 311 installed on the mounting tray 11.

[0051] Optionally, the condenser tube group 311 is arranged in the water collecting tank 111, so that the condenser tube group 311 can evaporate 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] Furthermore, at least a portion of the water collecting trough is opposite to the inlet collecting pipe in the up-down direction, and the lower end of the inlet collecting pipe extends into the water collecting trough; and / or, at least a portion of the water collecting trough is opposite to the outlet collecting pipe in the up-down direction, and the lower end of the outlet collecting pipe extends into the water collecting trough; in this way, the water collecting trough 111 can be used for the installation of the condenser 31, and the condensed water can be evaporated with the help of the heat dissipated by the condenser 31.

[0053] Specifically, the mounting tray 11 is provided with a water collecting trough 111, and the inlet collecting pipe 312 and the outlet collecting pipe 313 of the condenser 31 can be respectively extended into the water collecting trough 111 to realize the installation of the condenser 31 on the mounting tray 11, and the condenser tube group 311 is installed on the mounting tray 11, and the mounting tray 11 is provided with a heat dissipation through hole 112 opposite to the condenser tube group 311, so as to facilitate the refrigerant to realize air-cooling heat dissipation in the condenser tube group 311.

[0054] In addition, in some examples, the water collecting tank 111 includes a first water collecting tank and a second water collecting tank, the first water collecting tank and the second water collecting tank are arranged at intervals, the inlet manifold 312 extends into the first water collecting tank, and the outlet manifold 313 extends into the second water collecting tank, so as to realize the assembly of the condenser 31 on the mounting bracket 11. In other examples, the water collecting tank 111 extends from the inlet manifold 312 to the outlet manifold 313, and has a first inner side wall and a second inner side wall in the extending direction, the inlet manifold 312 and the outlet manifold 313 extend into the water collecting tank 111 respectively, and the inlet manifold 312 is limited to the first inner side wall of the water collecting tank 111, and the outlet manifold 313 is limited to the second inner side wall of the water collecting tank 111, so as to realize the installation limit of the condenser 31 on the mounting bracket 11.

[0055] like Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the mounting bracket 10 includes a mounting pallet 11 and a support frame 12, the support frame 12 is connected to the mounting pallet 11 and is arranged above the mounting pallet 11, and the cold tank assembly 20 is arranged on the support frame 12; in detail, the condensed water generated on the outer surface of the cold tank assembly 20 flows to the water collecting tank 111 of the mounting pallet 11 under the action of gravity and the diversion action of the support frame 12, thereby realizing the collection of condensed water and preventing the condensed water from overflowing or leaking.

[0056] In more detail, the support frame 12 has a mounting surface, and the cold tank assembly 20 is arranged on the mounting surface, and at least a portion of the mounting surface is tilted downward so that the condensed water generated by the cold tank assembly 20 can be diverted toward the water collecting tank; in this way, the condensed water generated by the cold tank assembly 20 can flow toward the support frame 12, and under the diversion action of the support frame 12, it can flow into the water collecting tank 111 of the mounting tray 11 to improve the collection efficiency of the condensed water.

[0057] In some specific examples, the support frame 12 extends in the up and down directions, the lower part of the support frame 12 is arranged on the mounting pallet 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 pallet 11 and have a gap with the mounting pallet 11, so that the condensed water generated on the outer surface of the cold tank assembly 20 can drip into the water collection tank 111 of the mounting pallet 11 under the action of gravity, thereby improving the collection efficiency of the condensed water.

[0058] like Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, the support frame 12 includes a first side plate 121, a second side plate 122 and a top plate 123, the top surface of the top plate 123 is set 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 between the support frame 12 and the cold tank assembly 20 can be increased, thereby improving the connection strength between 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 enclose an installation space, and the compressor 33, the condenser 31 and the throttling element 34 can all be arranged in the installation space, so that 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 compactly arranged in the up and down directions, which can improve the space utilization rate of the refrigeration device 100, and the top plate 123 can block at least a part of the structure of structural parts such as the compressor 33, the condenser 31 and the throttling element 34 to prevent condensation water from dripping and affecting the normal operation of the refrigeration device 100.

[0060] Furthermore, the top plate 123 is inclined toward the water collecting tank 111 in a preset horizontal direction and in a direction close to the water collecting tank 111; it can be understood that the top plate 123 has a third side edge and a fourth side edge relative to each other in the preset horizontal direction, the third side edge is close to the water collecting tank 111 relative to the fourth side edge, and the top plate 123 is inclined toward the water collecting tank 111 in a direction from the fourth side edge to the third side edge; in this way, the condensed water generated by the cold tank assembly 20 can flow to the top plate 123, and gather at the third side edge under the guiding effect of the top plate 123, and then can flow to the water collecting tank 111 of the mounting bracket 11 to improve the collection efficiency of the condensed water.

[0061] like Figures 2 to 4The heating unit includes a condenser 31, and the refrigeration component 30 includes an evaporator 32, a compressor 33 and a throttling element 34. 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 cooling 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 heat is released through the condenser 31. In this way, the heat emitted by the condenser 31 is used to heat the condensed water in the water collection tank 111, which can improve energy utilization and save costs.

[0062] In addition, the condenser 31 is arranged on the mounting bracket 10 and is arranged 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 drips downward under the action of gravity, so the condenser 31 can be arranged below the cold tank assembly 20, so that the condensed water dripping from the cold tank assembly 30 can drip on the condenser 31, and the condensed water can be evaporated by the phase change heat dissipation of the refrigerant in the condenser 31; and the condenser 31 and the cold tank assembly 20 are arranged compactly, which improves the space utilization. Similarly, the compressor 33 is arranged on the mounting bracket 10 and is arranged below the cold tank assembly 20, which can improve the compactness of the arrangement of the compressor and the cold tank assembly 20 and improve the space utilization. In addition, the evaporator 32 is arranged in the cold tank assembly 20 to improve the refrigeration effect of the cold tank assembly 20.

[0063] like Figure 1 , Figure 2 and Figure 3 In some embodiments of the present invention, 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, and the outer surface of the cold tank assembly 20 includes an outer top surface, an outer peripheral surface and an outer bottom surface. 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 gather at the first side edge under the guidance of the outer bottom surface of the cold tank assembly 20, and then flow to the water collecting tank 111 of the mounting bracket 11 to further improve the collection efficiency of condensed water.

[0064] In order to facilitate the collection of condensed water by the water collecting tank 111, there are many ways to set the water collecting tank 111 and the outer bottom surface of the cold tank assembly 20. The present invention provides the following embodiments for illustration:

[0065] Example 1

[0066] like Figure 3The water collecting groove 111 includes multiple water collecting grooves 111, and the first side edge extends along the front-to-back direction of the mounting bracket 11. The multiple water collecting grooves 111 are arranged at intervals along the front-to-back direction, and in the projection in the up-down direction, the projection of the first side edge and the projection of the water collecting groove 111 at least partially overlap; it can be understood that the arrangement direction of the multiple 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 multiple water collecting grooves 111 are opposite to the first side edge in the up-down direction. In this way, the condensed water on the first side edge of the outer bottom surface of the cold tank assembly 20 can be more easily collected by the multiple water collecting grooves 111, which is convenient for the heating unit to evaporate the condensed water in the water collecting groove 111 and improve the working stability of the refrigeration device 100.

[0067] Of course, in combination with the foregoing, in practice, the third side edge of the top plate 123 may also extend along the front-to-back direction of the mounting plate 11, and in the projection in the up-down direction, the third side edge at least partially overlaps with the projection of the water collecting tank 111, so that the condensed water flowing from the cold tank assembly 20 to the third side edge of the top plate 123 can be more easily collected by multiple water collecting tanks 111, which is convenient for the heating unit to evaporate the condensed water in the water collecting tank 111 and improve the working stability of the refrigeration device 100.

[0068] Example 2

[0069] The first side edge and the water collecting trough 111 extend along the front-to-back 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 overlaps with the projection of the water collecting trough 111; it can be understood that the extension direction of the water collecting trough 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 trough 111 is opposite to the first side edge in the up-down direction, so that the condensed water on the first side edge of the outer bottom surface of the cold tank assembly 20 can be more easily collected by the water collecting trough 111, which is convenient for the heating unit to evaporate the condensed water in the water collecting trough 111 and improve the working stability of the refrigeration device 100.

[0070] Similarly, there are many ways to set the water collecting tank 111 and the top plate 123. For example, multiple water collecting tanks 111 are opposite to the third side edge of the top plate 123 in the up-down direction, and the spacing arrangement direction of the multiple water collecting tanks 111 is consistent with the extension direction of the third side edge of the top plate 123; for another example, the water collecting tank 111 is opposite to the third side edge of the top plate 123 in the up-down direction, and the extension direction of the water collecting tank 111 is consistent with the extension direction of the third side edge of the top plate 123; the above examples can all facilitate the water collecting tank 111 to collect condensed water.

[0071] like Figure 2 and Figure 4In some embodiments of the present invention, the refrigeration assembly 30 also includes a heat dissipation fan 40, and the mounting bracket 10 is also provided with a heat dissipation through hole 112 opposite to the condenser 31. The heat dissipation fan 40 is arranged at the heat dissipation through hole 112. The heat dissipation fan 40 accelerates the circulation of airflow inside 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 tank 111 from flowing to the cooling fan 40 through the heat dissipation through-holes 112 and causing the condensed water to splash everywhere, the periphery of the heat dissipation through-holes 112 can be spaced apart from the water collecting tank 111 by a predetermined distance; further, the mounting bracket 10 is also provided with a flange 113, which extends in the up and down directions, the lower part of the flange 113 is connected to the periphery of the heat dissipation through-holes 112, and the upper part of the flange 113 can support the condenser 31, thereby blocking the condensed water on the mounting bracket 11, preventing the condensed water from flowing to the cooling fan 40 through the heat dissipation through-holes 112, and making the condensation tank group and the cooling fan 40 spaced apart by a predetermined distance to avoid structural interference.

[0073] like Figure 3 In some embodiments of the present invention, a portion of the inner surface of the mounting support plate 11 is recessed to form a water collecting tank 111. In this way, the water collecting tank 111 has a simple structure and low processing cost, and can realize the function of collecting condensed water.

[0074] In some embodiments of the present invention, the refrigeration device 100 also includes a first water leakage protection switch, which is arranged on the mounting bracket 10. The first water leakage protection switch can be used to detect water leakage in the refrigeration device 100. When the water flow inside the refrigeration device 100 reaches a preset water level, the first water leakage protection switch is triggered and cuts off the water path of the refrigeration device 100 to prevent continuous water leakage in the refrigeration device 100.

[0075] In addition, the first water leakage protection switch and the water collecting tank 111 are respectively arranged on the opposite sides of the mounting bracket 10 along the front-to-back direction; and / or, the first water leakage protection switch and the water collecting tank 111 are respectively arranged on the opposite sides of the mounting bracket 10 along the left-to-right direction; in this way, under the 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 guided into the water collecting tank 111, so as to prevent 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 invention, the heating unit also includes a heating tube and / or a PTC heater. It can be understood that the heating unit can heat the condensed water in the water collection tank 111 by electric heating, gas heating, etc. to achieve the purpose of evaporating the condensed water.

[0077] like Figures 1 to 5 According to the drinking water equipment 1000 of the embodiment of the present invention, the drinking water equipment 1000 includes the refrigeration device 100 in the above embodiment. By applying the above refrigeration device 100, the leakage of condensed water of the drinking water equipment 1000 can be avoided, and the operating stability of the drinking water equipment 1000 can be improved.

[0078] Specifically, the refrigeration device 100 is used in the drinking water equipment 1000, and the water in the cold tank assembly 20 is cooled by the evaporator 32 in the refrigerant circulation loop. In this way, the drinking water equipment 1000 can release cold drinking water that meets the user's needs through the cold tank assembly 20; but during the operation of the refrigeration device 100, due to the low temperature of the cold tank assembly 20, condensed water will be generated on the outer surface of the cold tank assembly 20, and the condensed water can flow to the water collecting tank 111 under the guidance of the outer bottom surface of the cold tank assembly 20 and the mounting bracket 10, and the condenser 31 in the refrigerant circulation loop can heat the condensed water in the water collecting tank 111, thereby evaporating the condensed water in the water collecting tank 111, avoiding overflow or leakage of the condensed water and accidentally touching the water leakage protection switch.

[0079] More specifically, the mounting bracket 10 includes a mounting tray 11 and a support frame 12, the support frame 12 includes a first side plate 121, a second side plate 122 and a top plate 123, the lower parts of the first side plate 121 and the second side plate 122 are connected to the mounting tray 11, and the upper parts are connected to the top plate 123, the water collecting tank 111 is arranged on the mounting tray 11, the cold tank assembly 20 is arranged above the top plate 123, the evaporator 32 is arranged in the cold tank assembly 20, the compressor 33, the condenser 31 and the throttling element 34 are arranged below the top plate 123, so that a plurality of structural members are arranged in the up and down directions, which can improve the compactness of the refrigeration device 100, and the top plate 123 can cover at least a part of the structure of the compressor 33, the condenser 31 and the throttling element 34 to prevent condensed water from affecting the normal operation of the refrigeration device 100.

[0080] Furthermore, 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, so that the condensed water generated by the cold tank assembly 20 can be guided to the first side edge, and the first side edge is opposite to the water collecting tank 111 in the up and down direction. In this way, under the action of gravity, the condensed water on the first side edge can drip into the water collecting tank 111 to improve the condensed water collection efficiency of the water collecting tank 111.

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

[0082] In addition, the condenser 31 includes an inlet collecting pipe 312 and an outlet collecting pipe 313, and the water collecting tank 111 includes a first water collecting tank and a second water collecting tank that are spaced apart. The inlet collecting pipe 312 can be extended into the first water collecting tank, and the outlet collecting pipe 313 can be extended into the second water collecting tank, so that the condenser 31 is installed on the mounting tray 11, thereby improving the installation strength of the condenser 31 on the mounting tray 11, and the condensed water in the water collecting tank 111 can be heated with the help of the temperature emitted by the inlet collecting pipe 312 and the outlet collecting pipe 313, thereby achieving the purpose of removing the condensed water.

[0083] like Figure 5 In some embodiments of the present invention, the drinking water equipment 1000 also includes a shell 200 and a second water leakage protection switch 300. The refrigeration device 100 and the second water leakage protection switch 300 are arranged in the shell 200. The second water leakage protection switch 300 can be used to detect water leakage of the drinking water equipment 1000. When the water flow inside the drinking water equipment 1000 reaches a preset water level, the second water leakage protection switch 300 is triggered and the water path of the drinking water equipment 1000 is cut off to prevent the drinking water equipment 1000 from continuous leakage.

[0084] In addition, the water collection tank 111 and the second water leakage protection switch 300 are respectively located on opposite sides of the outer shell 200 along the front-to-back direction; and / or, the water collection tank 111 and the second water leakage protection switch 300 are respectively located on opposite sides of the outer shell 200 along the left-to-right direction; in this way, under the guidance 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 and guided into the water collection tank 111, so as to prevent the condensed water generated by the cold tank assembly 20 from triggering the second water leakage protection switch 300 and affecting the normal operation of the refrigeration device 100.

[0085] It should be understood that, in the illustrated embodiment, the left-right direction of the housing 200 is consistent with the left-right direction of the mounting bracket 10 , and the front-back direction of the housing 200 is consistent with the front-back direction of the mounting bracket 10 .

[0086] like Figure 4In some specific examples of the present invention, the drinking water equipment 1000 also includes a water inlet flow path, a refrigeration flow path 400 and a water outlet flow path. The water inlet flow path is connected to the water inlet end of the cold tank assembly 20, and the water outlet flow path is connected to the water outlet end of the cold tank assembly 20. The refrigeration flow path 400 is respectively connected to the water inlet end and the water outlet end of the cold tank assembly 20, and is arranged inside the cold tank assembly 20. The evaporator 32 surrounds the refrigeration flow path 400 and is arranged at intervals. Water flow may be distributed between the evaporator 32 and the refrigeration flow path 400. The evaporator 32 cools the water in the cold tank assembly 20 and transfers the cold energy to the refrigeration flow path 400 through the water in the cold tank assembly 20, so that the temperature of the drinking water passing through the refrigeration flow path 400 is reduced. In this way, while producing low-temperature drinking water, it is possible to avoid the drinking water from freezing and being unable to be discharged.

[0087] also, Figure 4 The dash-dot arrows shown are used to indicate the assembly relationship of various structural components in the refrigeration device.

[0088] In some specific examples, the compressor 33 is a variable frequency compressor, and the condenser 31 is a microchannel condenser; the refrigeration device 100 in this scheme may have the function of collecting condensed water and evaporating condensed water; specifically, the mounting bracket 11 is respectively designed with two water collecting tanks 111 at the inlet collecting pipe 312 and the outlet collecting pipe 313 of the serpentine microchannel condenser, which are used to collect the condensed water generated during the refrigeration process. During the refrigeration process, the inlet and outlet pipe temperatures of the condenser 31 are relatively high, and the condensed water can be evaporated by utilizing its heat, thereby preventing the condensed water from flowing out of the refrigeration device 100 or the drinking water equipment 1000, and at the same time, it can effectively prevent the condensed water from overflowing inside and accidentally triggering the water leakage protection switch.
