Detailed Implementation

[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] This utility model proposes a refrigeration device 100 for a drinking water device 1000. It collects condensate generated inside the device through a water collection tank 111 and evaporates the condensate in the water collection tank 111 through a high-temperature pipe assembly, preventing condensate from overflowing or leaking inside the device and affecting the normal operation of the refrigeration device 100. Additionally, a drinking water device 1000 is also proposed, which includes the aforementioned refrigeration device 100.

[0036] like Figures 1 to 5 According to an embodiment of the present invention, a refrigeration device 100 for a drinking water equipment 1000 includes a mounting bracket 10, a cold tank assembly 20, and a refrigeration assembly 30.

[0037] The mounting bracket 10 is equipped with a water collection tank 111, and the cold tank assembly 20 is mounted on the mounting bracket 10. The mounting bracket 10 is configured to guide the condensate generated by the cold tank assembly 20 to the water collection tank 111. The refrigeration assembly 30 is configured to use a refrigerant phase change to cool the water in the cold tank assembly 20. The refrigeration assembly 30 includes a compressor 33, a high-temperature tube group, and a low-temperature tube group. The high-temperature tube group includes a condenser 31, and the low-temperature tube group includes an evaporator 32. At least a portion of the high-temperature tube group is configured to heat the water in the water collection tank 111, and at least a portion of the low-temperature tube group is configured to cool the water in the cold tank assembly 20. This configuration can prevent condensate from overflowing or leaking inside the device, thus avoiding affecting the normal operation of the refrigeration device 100.

[0038] For example, the refrigeration device 100 is used in the drinking water equipment 1000 for cooling drinking water. Specifically, the inlet end of the cold tank assembly 20 is provided with an inlet flow path, and the outlet end of the cold tank assembly 20 is provided with an outlet flow path. The water flows through the inlet flow path, the cold tank assembly 20 and the outlet flow path in sequence. The low temperature tube group cools the water flowing through the cold tank assembly 20, so as to realize the cold water output of the drinking water equipment 1000. During the aforementioned working process, due to the low temperature of the cold tank assembly 20, condensate is generated on the outer surface of the cold tank assembly 20. The mounting bracket 10 guides the condensate to the water collection tank 111, thereby collecting the condensate and preventing the condensate from flowing to other parts of the refrigeration device 100 or the drinking water equipment 1000, which would affect the normal operation of the drinking water equipment 1000. Subsequently, the condensate in the water collection tank 111 is heated and evaporated by the high temperature tube group.

[0039] In addition, the high-temperature pipe assembly, the cold tank assembly 20 and the compressor 33 can all be set on the mounting bracket 10, and the refrigeration unit 100 can be installed in the water drinking equipment 1000 through the mounting bracket 10, thereby improving the integration of the water drinking equipment 1000 and the assembly efficiency.

[0040] Therefore, the refrigeration device 100 for drinking water equipment 1000 according to the present utility model embodiment can collect the condensate generated inside the device through the water collection tank 111 and evaporate the condensate in the water collection tank 111 through the high temperature tube group, so as to avoid the condensate overflowing or leaking inside the device and affecting the normal operation of the refrigeration device 100.

[0041] In some embodiments of this utility model, the high-temperature pipe assembly also includes a refrigerant pipe connected between the compressor 33 and the evaporator 32. The refrigerant pipe is connected in series with the condenser 31, and at least a portion of the refrigerant pipe is configured to heat the water in the water collection tank 111. Specifically, since the refrigerant has high heat exchange efficiency, the refrigerant pipe can heat the condensate in the water collection tank 111 by means of the heat release from the phase change of the refrigerant. When the refrigeration device 100 is working, the high-temperature refrigerant flows through the refrigerant pipe and transfers heat to the water collection tank 111, so that the condensate in the water collection tank 111 is heated and evaporated, so as to avoid the overflow or leakage of condensate.

[0042] Furthermore, the refrigeration assembly also includes a throttling element 34, and the refrigerant pipes include a first refrigerant pipe and a second refrigerant pipe. The first refrigerant pipe is connected between the compressor 33 and the condenser 31, and the second refrigerant pipe is connected between the condenser 31 and the throttling element 34. In this way, when the refrigeration device 100 is working, the refrigerant circulation is in 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. Thus, the first refrigerant pipe and / or the second refrigerant pipe can be constructed as a high-temperature pipe assembly. The heat dissipated by the first refrigerant pipe and / or the second refrigerant pipe heats the condensate in the water collection tank 111, which can improve energy utilization and save costs.

[0043] It is understandable that the condenser 31, the throttling element 34, the evaporator 32 and the compressor 33 are connected to form a refrigerant circulation loop.

[0044] Furthermore, the condenser 31 includes a condenser tube assembly 311, an inlet manifold 312, and an outlet manifold 313. The condenser tube assembly 311 is connected between the inlet manifold 312 and the outlet manifold 313. The condenser tube assembly 311, the inlet manifold 312, and / or the outlet manifold 313 are configured as a high-temperature tube assembly and are distributed opposite to the water collection tank 111. This arrangement can improve the evaporation efficiency of condensate and prevent condensate overflow or leakage.

[0045] It is understood that the condenser coil assembly 311 includes multiple condenser pipes, the inlet manifold 312 is connected to the inlet end of the multiple condenser coil assemblies 311, and the outlet manifold 313 is connected to the outlet end of the multiple condenser pipes. When the high-temperature refrigerant flows through the condenser 31, it first passes through the inlet manifold 312, where a large amount of high-temperature refrigerant is collected and distributed to the multiple condenser pipes to improve the heat exchange efficiency of the condenser 31. Subsequently, the refrigerant in the multiple condenser pipes is collected again at the outlet manifold. The refrigerant is collected in pipe 313 and discharged from condenser 31. Therefore, the refrigerant in the inlet manifold 312 and outlet manifold 313 of condenser 31 is relatively concentrated and at a high temperature. The condenser tube group 311, inlet manifold 312 and / or outlet manifold 313 can be constructed as a high-temperature tube group. In this way, the condensate in the water collection tank 111 can be heated by the condenser tube group 311, inlet manifold 312 and / or outlet manifold 313, which can improve the evaporation efficiency of the condensate and prevent the condensate from overflowing or leaking.

[0046] In addition, the condenser tube assembly 311, the inlet manifold 312 and / or the outlet manifold 313 can be distributed opposite to the water collection tank 111, so that the heat of the inlet manifold 312 and / or the outlet manifold 313 can be better transferred to the water collection tank 111, thereby further improving the evaporation efficiency of the condensate.

[0047] In addition, in some specific examples, the condenser 31 may be a microchannel condenser 31.

[0048] like Figures 1 to 4 In some embodiments of this utility model, the mounting bracket 10 includes a mounting plate 11, a condenser tube assembly 311 is mounted on the mounting plate 11, and a water collection tank 111 is disposed on the mounting plate 11; with this arrangement, the heat emitted by the condenser tube assembly 311 mounted on the mounting plate 11 can evaporate the condensate in the water collection tank 111.

[0049] Optionally, the condenser coil assembly 311 is located inside the water collection tank 111 to facilitate the evaporation of condensate in the water collection tank 111 by the condenser coil assembly 311. Optionally, the condenser coil assembly 311 is located above the water collection tank 111, and the condenser coil assembly 311 can be configured as a heat source above the water collection tank 111 to heat the condensate in the water collection tank 111 through indirect heating.

[0050] Furthermore, at least a portion of the water collection tank 111 is vertically opposite to the inlet manifold 312, with the lower end of the inlet manifold 312 extending into the water collection tank 111; and / or, at least a portion of the water collection tank 111 is vertically opposite to the outlet manifold 313, with the lower end of the outlet manifold 313 extending into the water collection tank 111; thus, the water collection tank 111 can be used for the installation of the condenser 31, and the condensate can be evaporated by the heat dissipated by the condenser 31.

[0051] Specifically, the mounting plate 11 is provided with a water collection tank 111, and the inlet manifold 312 and outlet manifold 313 of the condenser 31 can be respectively inserted into the water collection tank 111 to realize the installation of the condenser 31 on the mounting plate 11. The condenser tube assembly 311 is installed on the mounting plate 11, and the mounting plate 11 is provided with heat dissipation through holes 112 opposite to the condenser tube assembly 311 to facilitate the refrigerant to achieve air cooling in the condenser tube assembly 311.

[0052] In some examples, the water collection tank 111 includes a first water collection tank and a second water collection tank, which are spaced apart. The inlet manifold 312 extends into the first water collection tank, and the outlet manifold 313 extends into the second water collection tank, thereby enabling the condenser 31 to be mounted on the mounting plate 11. In other examples, the water collection tank 111 extends from the inlet manifold 312 to the outlet manifold 313 and has a first inner sidewall and a second inner sidewall in the extending direction. The inlet manifold 312 and the outlet manifold 313 extend into the water collection tank 111, with the inlet manifold 312 confined to the first inner sidewall of the water collection tank 111 and the outlet manifold 313 confined to the second inner sidewall of the water collection tank 111, thereby limiting the installation of the condenser 31 on the mounting plate 11.

[0053] like Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, 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 located above the mounting plate 11. The cold tank assembly 20 is mounted on the support frame 12. Specifically, the condensate generated on the outer surface of the cold tank assembly 20 flows to the water collection tank 111 of the mounting plate 11 under the action of gravity and the guiding action of the support frame 12, thereby realizing the collection of condensate and preventing condensate from overflowing or leaking.

[0054] More specifically, the support frame 12 has a mounting surface, on which the cold tank assembly 20 is disposed. At least a portion of the mounting surface is inclined downwards to guide the condensate generated by the cold tank assembly 20 toward the water collection tank. In this way, the condensate generated by the cold tank assembly 20 can flow toward the support frame 12 and, under the guiding action of the support frame 12, flow into the water collection tank 111 of the mounting plate 11, thereby improving the condensate collection efficiency.

[0055] In some specific examples, the support frame 12 extends vertically, with the lower part of the support frame 12 located on the mounting plate 11 and the cold tank assembly 20 located on the upper part of the support frame 12. In this way, the cold tank assembly 20 can be set higher than the mounting plate 11 and there is a gap between them, so that the condensate generated on the outer surface of the cold tank assembly 20 can drip into the water collection tank 111 of the mounting plate 11 under the action of gravity, thereby improving the condensate collection efficiency.

[0056] like Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, 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 vertical 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. 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.

[0057] Furthermore, in some specific examples, the first side plate 121, the second side plate 122, and the top plate 123 enclose an installation space, in which the compressor 33, the condenser 31, and the throttling element 34 can all be installed. 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 vertical direction, which can improve the space utilization of the refrigeration device 100. Moreover, 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, preventing condensate from dripping and affecting the normal operation of the refrigeration device 100.

[0058] Furthermore, the top plate 123 is inclined toward the water collection tank 111 in a predetermined horizontal direction and close to the water collection tank 111. It is understood that the top plate 123 has a third side edge and a fourth side edge opposite to each other in a predetermined horizontal direction, the third side edge being closer to the water collection tank 111 relative to the fourth side edge, and the top plate 123 is inclined toward the water collection tank 111 in the direction from the fourth side edge to the third side edge. In this way, the condensate generated by the cold tank assembly 20 can flow to the top plate 123 and be collected at the third side edge under the guiding effect of the top plate 123, and then flow into the water collection tank 111 where the support plate 11 is installed, so as to improve the condensate collection efficiency.

[0059] like Figures 2 to 4 In some embodiments of this utility model, at least a portion of the condenser 31 is configured to heat the water in the water collection tank 111. The refrigeration assembly 30 includes a throttling element 34, an evaporator 32, and a compressor 33. The condenser 31, the throttling element 34, the evaporator 32, and the compressor 33 are connected to form a refrigerant circulation loop. Thus, when the refrigeration device 100 is working, the refrigerant circulation loop is in 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 emitted by the condenser 31 can heat the condensate in the water collection tank 111, thereby improving energy utilization and saving costs.

[0060] Furthermore, the condenser 31 is mounted on the mounting bracket 10 and positioned below the cold tank assembly 20. It is understood that condensate generated on the outer surface of the cold tank assembly 30 drips downwards under gravity. Therefore, by positioning the condenser 31 below the cold tank assembly 20, the dripping condensate from the cold tank assembly 30 can fall onto the condenser 31, where it evaporates through phase change heat dissipation using the refrigerant. This compact arrangement of the condenser 31 and the cold tank assembly 20 improves space utilization. Similarly, the compressor 33 is mounted on the mounting bracket 10 and positioned below the cold tank assembly 20, further enhancing the compactness of the compressor and cold tank assembly 20 arrangement and improving space utilization. Additionally, the evaporator 32 is located within the cold tank assembly 20 to improve its cooling effect.

[0061] like Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the outer bottom surface of the cold tank assembly 20 has a first side edge close to the water collection tank 111 and a second side edge away from the water collection tank 111. The outer bottom surface of the cold tank assembly 20 is inclined toward the water collection tank 111 in the direction from the second side edge to the first side edge. It can be understood that the water collection 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 includes an outer top surface, an outer peripheral surface, and an outer bottom surface. The condensate generated on the outer top surface and outer peripheral surface of the cold tank assembly 20 can flow toward the outer bottom surface under the action of gravity, and gather at the first side edge under the guiding action of the outer bottom surface of the cold tank assembly 20. Then it can flow into the water collection tank 111 where the mounting plate 11 is installed, so as to further improve the condensate collection efficiency.

[0062] To facilitate the collection of condensate in the water collection tank 111, there are various ways to arrange the water collection tank 111 and the outer bottom surface of the cold tank assembly 20. The present invention provides the following embodiments for illustration:

[0063] Example 1

[0064] like Figure 3 In some embodiments of this utility model, the water collection tank 111 includes multiple tanks, with the first side edge extending along the front-rear direction of the mounting bracket 10. The multiple water collection tanks 111 are arranged at intervals along the front-rear direction, and in the vertical projection, the projection of the first side edge and the projection of the water collection tank 111 at least partially overlap. It can be understood that the arrangement direction of the multiple water collection tanks 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 collection tanks 111 are opposite to the first side edge in the vertical direction. In this way, the condensate on the first side edge of the outer bottom surface of the cold tank assembly 20 can be easily collected by the multiple water collection tanks 111, which facilitates the evaporation of the condensate in the water collection tank 111 by the high-temperature tube group and improves the working stability of the refrigeration device 100.

[0065] Of course, in practice, in conjunction with the foregoing, the third side edge of the top plate 123 can also extend along the front-back direction of the mounting bracket 10, and in the projection in the vertical direction, the projection of the third side edge and the water collection tank 111 at least partially overlap, so that the condensate flowing from the cold tank assembly 20 to the third side edge of the top plate 123 can be collected more easily by multiple water collection tanks 111, which facilitates the evaporation of the condensate in the water collection tank 111 by the high-temperature tube assembly and improves the working stability of the refrigeration device 100.

[0066] Example 2

[0067] In some embodiments of this utility model, the first side edge and the water collection tank 111 extend along the front-rear direction of the mounting bracket 10, and in the vertical projection, the projection of the first side edge and the projection of the water collection tank 111 at least partially coincide. It can be understood that the extension direction of the water collection tank 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 collection tank 111 and the first side edge are opposite each other in the vertical direction. In this way, the condensate on the first side edge of the outer bottom surface of the cold tank assembly 20 can be collected by the water collection tank 111 more easily, which facilitates the evaporation of the condensate in the water collection tank 111 by the high-temperature tube group and improves the working stability of the refrigeration device 100.

[0068] Similarly, there are various ways to arrange the water collection tank 111 and the top plate 123. For example, multiple water collection tanks 111 are opposite to the third side edge of the top plate 123 in the vertical direction, and the spacing of the multiple water collection tanks 111 is consistent with the extension direction of the third side edge of the top plate 123; or, the water collection tanks 111 are opposite to the third side edge of the top plate 123 in the vertical direction, and the extension direction of the water collection tanks 111 is consistent with the extension direction of the third side edge of the top plate 123. All of the above examples can facilitate the collection of condensate by the water collection tank 111.

[0069] like Figure 2 and Figure 4 In some embodiments of this utility model, the refrigeration assembly 30 further includes a cooling fan 40, and the mounting bracket 10 is also provided with a heat dissipation through hole 112 opposite to the condenser 31. The cooling fan 40 is located at the heat dissipation through hole 112. The cooling fan 40 accelerates the 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.

[0070] Furthermore, to prevent condensate in the water collection tank 111 from flowing to the cooling fan 40 through the heat dissipation hole 112 and causing condensate to splash everywhere, the periphery of the heat dissipation hole 112 can be spaced apart from the water collection tank 111 by a predetermined distance. In addition, the mounting bracket 10 is also provided with a flange 113, which extends in the vertical direction. The lower part of the flange 113 connects to the periphery of the heat dissipation hole 112, and the upper part of the flange 113 can support the condenser 31, thereby blocking the condensate on the mounting bracket 10, preventing the condensate from flowing to the heat dissipation dispersion through the heat dissipation hole 112, and making the condenser tank assembly and the cooling fan 40 spaced apart by a predetermined distance to avoid structural interference.

[0071] like Figure 3 In some embodiments of this utility model, a portion of the inner surface of the mounting plate 11 is recessed to form a water collection trough 111. In this way, the water collection trough 111 has a simple structure, low processing cost, and can realize the function of collecting condensate.

[0072] In some embodiments of this utility model, the refrigeration device 100 further includes a first water leakage protection switch. The first water leakage protection switch is disposed on the mounting bracket 10. The first water leakage protection switch can be used to detect the water leakage of 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 the water path of the refrigeration device 100 is cut off to prevent the refrigeration device 100 from continuously leaking water.

[0073] Furthermore, the first water leakage protection switch and the water collection tank 111 are respectively located on opposite sides of the mounting bracket 10 in the front-to-back direction; and / or, the first water leakage protection switch and the water collection tank 111 are respectively located on opposite sides of the mounting bracket 10 in the left-to-right direction; thus, 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 condensate generated on the outer surface of the cold tank assembly 20 can be guided away from the first water leakage protection switch and into the water collection tank 111, so as to prevent the condensate 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.

[0074] like Figures 1 to 5 According to the present utility model, the drinking water device 1000 includes the refrigeration device 100 in the above embodiment. By applying the aforementioned refrigeration device 100, the leakage of condensate from the drinking water device 1000 can be avoided, thereby improving the operational stability of the drinking water device 1000.

[0075] Specifically, the refrigeration device 100 is used in the drinking water equipment 1000. The refrigeration component 30 includes a refrigerant circulation loop. The evaporator 32 in the refrigerant circulation loop cools the water in the cold tank component 20. In this way, the drinking water equipment 1000 can release cold drinking water that meets the user's needs through the cold tank component 20. However, during the operation of the refrigeration device 100, due to the low temperature of the cold tank component 20, condensate will be generated on the outer surface of the cold tank component 20. The condensate can flow to the water collection tank 111 under the guidance of the outer bottom surface of the cold tank component 20 and the mounting bracket 10. The condenser 31 in the refrigerant circulation loop can be thermally connected to the wall of the water collection tank 111 to heat the condensate in the water collection tank 111, thereby evaporating the condensate in the water collection tank 111, preventing the condensate from overflowing or leaking, and preventing accidental triggering of the leakage protection switch.

[0076] More specifically, the mounting bracket 10 includes a mounting plate 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 part of the first side plate 121 and the second side plate 122 are connected to the mounting plate 11, while the upper part is connected to the top plate 123. A water collection tank 111 is disposed on the mounting plate 11. The cold tank assembly 20 is disposed above the top plate 123. The evaporator 32 is disposed inside the cold tank assembly 20. The compressor 33, the condenser 31, and the throttling element 34 are disposed below the top plate 123. In this way, multiple structural components are arranged in the vertical direction, which can improve the compactness of the refrigeration device 100. The top plate 123 can shield at least a part of the structure of the compressor 33, the condenser 31, and the throttling element 34, so as to prevent condensate from affecting the normal operation of the refrigeration device 100.

[0077] Furthermore, the outer bottom surface of the cold tank assembly 20 has a first side edge close to the water collection tank 111 and a second side edge away from the water collection tank 111. The outer bottom surface of the cold tank assembly 20 is inclined toward the water collection tank 111 in the direction from the second side edge to the first side edge, so that the condensate generated by the cold tank assembly 20 can be guided to the first side edge. The first side edge is opposite to the water collection tank 111 in the vertical direction. In this way, under the action of gravity, the condensate on the first side edge can drip into the water collection tank 111 to improve the condensate collection efficiency of the water collection tank 111.

[0078] Furthermore, the top plate 123 of the support frame 12 has a third side edge close to the water collection tank 111 and a fourth side edge away from the water collection tank 111. The top plate 123 is inclined toward the water collection tank 111 in the direction from the fourth side edge to the third side edge, so that the condensate 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 collection tank 111 in the vertical direction. In this way, under the action of gravity, the condensate on the third side edge can drip into the water collection tank 111 to improve the condensate collection efficiency of the water collection tank 111.

[0079] In addition, the condenser 31 includes an inlet manifold 312 and an outlet manifold 313, and the water collection tank 111 includes a first water collection tank and a second water collection tank arranged at intervals. The inlet manifold 312 can extend into the first water collection tank, and the outlet manifold 313 can extend into the second water collection tank, thereby installing the condenser 31 on the mounting plate 11, improving the installation strength of the condenser 31 on the mounting plate 11, and the condensate in the water collection tank 111 can be heated by the temperature emitted by the inlet manifold 312 and the outlet manifold 313, so as to remove the condensate.

[0080] like Figure 5 In some embodiments of this utility model, the drinking water device 1000 also includes a housing 200 and a second water leakage protection switch 300. The cooling device 100 and the second water leakage protection switch 300 are disposed inside the housing 200. The second water leakage protection switch 300 can be used to detect the water leakage of the drinking water device 1000. When the water flow inside the drinking water device 1000 reaches a preset water level, the second water leakage protection switch 300 is triggered and the water path of the drinking water device 1000 is cut off to prevent the drinking water device 1000 from continuously leaking water.

[0081] Furthermore, the water collection tank 111 and the second water leakage protection switch 300 are located on opposite sides of the housing 200 along the front-rear direction; and / or, the water collection tank 111 and the second water leakage protection switch 300 are located on opposite sides of the housing 200 along the left-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 condensate 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 avoid the condensate generated by the cold tank assembly 20 triggering the second water leakage protection switch 300 and affecting the normal operation of the refrigeration device 100.

[0082] 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.

[0083] like Figure 4In some specific examples of this utility model, the drinking water device 1000 further includes an inlet flow path, a cooling flow path 400, and an outlet flow path. The inlet flow path is connected to the inlet end of the cold tank assembly 20, and the outlet flow path is connected to the outlet end of the cold tank assembly 20. The cooling flow path 400 is connected to the inlet end and the outlet end of the cold tank assembly 20 respectively, and is disposed inside the cold tank assembly 20. The evaporator 32 is arranged around the cooling flow path 400 and spaced apart. Water flow can be distributed between the evaporator 32 and the cooling flow path 400. The evaporator 32 cools the water in the cold tank assembly 20 and transfers the cooling energy to the cooling flow path 400 through the water in the cold tank assembly 20, so that the temperature of the drinking water passing through the cooling flow path 400 is reduced. In this way, low-temperature drinking water can be produced while avoiding the drinking water freezing and becoming unusable.

[0084] also, Figure 4 The dotted-line arrows shown are used to indicate the assembly relationship of various structural components in the refrigeration unit.

[0085] In some specific examples, compressor 33 is a variable frequency compressor, and condenser 31 is a microchannel condenser; the refrigeration device 100 in this solution can have the functions of collecting condensate and evaporating condensate; specifically, the mounting plate 11 is designed with two water collection tanks 111 at the inlet manifold 312 and outlet manifold 313 of the serpentine microchannel condenser, respectively, to collect the condensate generated during the refrigeration process. During the refrigeration process, the inlet and outlet pipes of condenser 31 are at high temperatures, and the condensate can be evaporated by its heat, thereby preventing the condensate from flowing out of the refrigeration device 100 or the drinking water equipment 1000, and at the same time effectively preventing the condensate from overflowing inside and accidentally triggering the leakage protection switch.
