[0042] Drinking water equipment is a water supply equipment used in home, commercial and industrial environments. Its main function is to provide people with drinkable water. At present, it is divided into barrel water supply and direct drinking water supply according to the water supply method. The barrel water supply type uses barreled water to supply water to the drinking water equipment, and the direct drinking water equipment has its water inlet directly connected to a water supply source such as a tap, and the direct drinking water equipment generally has a water purification function.

[0043] In order to meet the water temperature requirements of different groups of people, today's drinking water equipment has both heating and cooling functions; in the relevant refrigeration equipment, the compressor is the core component to pressurize the refrigerant, thereby promoting the gas-liquid conversion of the refrigerant, and then using the gas-liquid conversion of the refrigerant to complete the absorption and release of heat to complete refrigeration; At present, some compressors have been miniaturized and are particularly suitable for small-volume equipment such as drinking water equipment, refrigerators and small floor-standing air conditioners.

[0044] However, in order to cooperate with the heat absorption and release process of the refrigerant during the gas-liquid conversion, in addition to the compressor, a condenser and an evaporator are also needed to cooperate with the gas-liquid conversion of the refrigerant, thereby completing the heat transfer; specifically, the refrigerant after being pressurized by the compressor will become liquid, and then enter the condenser, and condense and cool down in the condenser; the cooled liquid refrigerant will enter the evaporator, and the evaporator is generally tightly fitted with the equipment or parts to be cooled, so that the heat of the equipment and parts to be cooled can be transferred to the evaporator, and the refrigerant in the evaporator will evaporate due to the heat, that is, the liquid evaporates into gas; the evaporation process of the refrigerant will take away a large amount of heat, so that the evaporator can absorb a large amount of heat from the equipment and parts to be cooled, thereby completing the refrigeration.

[0045] Reference Figure 1 , Figure 2 Based on the above, the utility model proposes a drinking water device, including a cold tank module, a compressor 3, a condenser 4 and a base 11; wherein, in the height direction, the cold tank module is arranged at the top, the cold tank module includes a tank body 2 and an evaporator 5, the compressor 3 is arranged below the cold tank module, the base 11 and the condenser 4 are combined into one, and are jointly arranged below the compressor 3; it should be noted that a bracket 12 is arranged on the base 11, and the base 11 and the bracket 12 together form a frame 1.

[0046] Reference Figure 3 , Figure 4 Therefore, when the drinking water equipment starts the refrigeration function to cool the water, the surface temperature of the tank body 2 will decrease, so condensed water may be generated on the surface of the tank body 2. The tank body 2 and the compressor 3 and other components are all arranged inside the drinking water equipment, so the condensed water on the surface of the tank body 2 is difficult to evaporate. Over time, the condensed water is likely to gather into drops and fall down; in addition, if the tank body 2 is not well sealed, water leakage may also occur.

[0047] Regardless of how the water is generated, since the compressor 3 is located below the tank body 2, water droplets are likely to drip onto the compressor 3 under the action of gravity. The compressor 3 has a power interface 311, and the power interface 311 of the compressor 3 is located on its outer wall. Therefore, when water droplets fall, they are likely to directly contact the power interface 311 of the compressor 3, thereby causing a short circuit failure of the compressor 3.

[0048] In order to solve the above problems, in the drinking water equipment proposed in the present invention, a protective cover 32 is provided on the power interface 311 of the compressor 3, and the protective cover 32 is used to shield the power interface 311 to prevent water droplets from directly dripping onto the power supply; in the present invention, the protective cover 32 is detachably arranged on the compressor 3, thereby facilitating the installation and removal of the protective cover 32, thereby facilitating the assembly of the compressor 3 or the maintenance of the compressor 3.

[0049] Reference Figures 5 to 7The protective cover 32 is provided with a fixing piece 33, and the fixing piece 33 is detachably connected to the compressor 3, that is, the connection between the fixing piece 33 and the side wall of the compressor 3 will fix the protective cover 32 on the compressor 3, thereby completing the installation of the compressor 3; in the utility model, limiting plates 312 are provided on the opposite sides of the power interface 311, and buckle holes 312a are opened on the limiting plates 312, and the protective cover 32 is arranged between the two limiting plates 312, and the fixing piece 33 is buckled with the limiting plates 312 through the buckle holes 312a; the buckling cooperation of the fixing piece 33 and the limiting plates 312 will fix the protective cover 32 to the outer wall of the compressor 3, and the protective cover 32 can be removed by contacting the cooperation between the fixing piece 33 and the limiting plates 312; the above structure can fix the protective cover 32, thereby ensuring the protective effect of the protective cover 32 and reducing the possibility of water droplets falling onto the power interface 311; it can also complete the disassembly of the protective cover 32, which is convenient for later inspection and maintenance.

[0050] In the present invention, the fixing member 33 includes a deformation plate 331 and two connecting plates 332. The deformation plate 331 has two ends, and the two ends of the deformation plate 331 are bent, one end of the two connecting plates 332 is respectively arranged at the two ends of the deformation plate 331, and the other end of the connecting plate 332 is buckled with the buckle hole 312a; it should be noted that in the actual production process, the deformation plate 331, that is, the connecting plate 332 is integrally formed, and the deformation plate 331 and the connecting plate 332 can be made of materials with deformation ability such as plastic and metal, thereby, the deformation plate 331 The end, that is, the connection between the deformable plate 331 and the connecting plate 332 has a strong deformation ability due to the bending setting. It can be generally understood that both the deformable plate 331 and the connecting plate 332 are elastic, so that the elastic deformation of the deformable plate 331 and the connecting plate 332 can be used to complete the buckling between the fixing member 33 as a whole and the limiting plate 312, and the disassembly can also be completed at the same time; in addition, the bending setting of the end of the deformable plate 331 is equivalent to providing deformation space for the deformable plate 331 and the connecting plate 332, thereby reducing the possibility of the connecting plate 332 and the deformable plate 331 being fractured due to stress during the deformation process.

[0051] Reference Figures 5 to 7 When the deformation plate 331 is deformed, that is, the end of the connecting plate 332 is buckled with the limiting plate 312, the deformation of the deformation plate 331 will press the protective cover 32 against the side wall of the compressor 3, thereby completing the fixation of the compressor 3; and in order to buckle the outer connecting plate 332 and the limiting plate 312, a buckle plate 333 is provided at the end of the connecting plate 332 away from the deformation plate 331. When buckling, the buckle plate 333 passes through the buckle hole 312a and contacts the inner wall of the buckle hole 312a, thereby completing the buckle.

[0052] According to the above description, the fixing member 33 can be buckled with the limiting plate 312 to complete the fixation of the protective cover 32. In order to facilitate the operator to complete the installation of the protective cover 32 and the fixing member 33, the angle between the buckle plate 333 and the connecting plate 332 can be made less than 90°, so that the buckle plate 333 itself can play a certain guiding role during the installation process. There is no need for the installer to pry open the fixing member 33 in advance to allow the buckle plate 333 to pass through the buckle hole 312a. The buckle plate 333 can be aligned with the position of the buckle hole 312a in the horizontal direction and then the fixing member 33 can be pushed. During the pushing process, the angle setting between the buckle plate 333 and the connecting plate 332 will cause the connecting plate 332 and the deformation plate 331 to deform. When the buckle plate 333 is inserted into the buckle hole 312a, the deformation plate 331 and the connecting plate 332 release the previous elastic deformation to complete the buckle plate 333 and the buckle hole 312a.

[0053] In consideration of the possibility that the connection plate 332 and the buckle plate 333 may break due to excessive deformation during the buckling process, a bending portion 334 is provided on the connection plate 332. The setting of the bending portion 334 will further increase the upper limit of the deformation of the connection plate 332, thereby reducing the possibility of the connection plate 332 and the buckle plate 333 breaking due to excessive deformation, thereby ensuring the integrity of the overall structure; in addition, the setting of the bending portion 334 can make way for the limiting plate 312 during the buckling process of the fixing member 33, that is, the setting of the bending portion 334 reduces the connection plate 332 The requirement on the deformation amount of the deformation plate 331 during the buckling process further reduces the possibility of the overall structure breaking due to excessive deformation during installation or disassembly; in addition, the setting of the bending portion 334 provides a force point for the installer when removing the fixing member 33, that is, when the fixing member 33 is buckled with the limiting plate 312, the installer can pinch the bending portion 334 to cause the fixing member 33 to deform as a whole and break away from the buckling state with the limiting plate 312. Therefore, the setting of the bending portion 334 also further improves the convenience of installing or disassembling the fixing member 33.

[0054] Reference Figures 5 to 7 In the present invention, in order to ensure the fixing effect of the fixing member 33 on the protective cover 32, that is, to reduce the possibility of the protective cover 32 being displaced over a large range after installation and thus falling off, two limit bars 322 are formed on the outer peripheral wall of the protective cover 32, and the two limit bars 322 jointly limit the fixing member 33; it should be noted that although the two limit bars 322 here limit the movable range of the fixing member 33 compared to the protective cover 32, when the fixing member 33 is buckled with the limit plate 312, the fixing member 33 will not move, so that the limit bars 322 actually limit the movable range of the protective cover 32; refer to Figure 3The limit strip 322 actually limits the movement of the protective cover 32 in the up and down directions, and the protective cover 32 is arranged between the two limit plates 312, and the fixing member 33 cooperates with the limit plates 312 to press the protective cover 32 against the compressor 3, that is, the two limit plates 312 and the fixing member 33 jointly limit the displacement of the protective cover 32 in the horizontal direction, further improving the stability of the protective cover 32 after installation, and ensuring the protective effect of the protective cover 32 on the power interface 311. Based on the above description, in order to further improve the stability of the protective cover 32, a protrusion 323 is formed on the end of the limiting strip 322. The protrusion 323 will conflict with the limiting plate 312 when the protective cover 32 is displaced upward or downward, thereby preventing the displacement trend of the protective cover 32; in addition, the provision of the protrusion 323 also further improves the convenience of the overall structure during installation; during installation, the limiting plate 312 can be aligned with the gap between the two adjacent protrusions 323, that is, the two adjacent protrusions 323 can provide a positioning function during the installation process of the protective cover 32, further improving the convenience of the protective cover 32 during installation.

[0055] Correspondingly, in order to supply power to the compressor 3 normally, a wiring opening 321 is opened on one side wall of the protective cover 32, and the wiring opening 321 is used for the external power line to pass through; wherein, in order to fix the bottom line, a wire fixing plate 313 can be further provided on the side wall of the compressor 3, and a plurality of wire passing holes 614 are opened on the wire fixing plate 313, so that the ground wire and other wires can be fixed through the wire fixing plate 313; the specific shape and number of the wire fixing plate 313 and the number of wire passing holes 614 can be changed according to actual design requirements. In the utility model, the wire fixing plate 313 and the wiring opening 321 are arranged correspondingly to complete the fixation of the ground wire.

[0056] Reference Figures 5 to 7 It should be noted that at this time, two additional limit plates 312 and a fixing plate 313 are additionally provided on the outer wall of the compressor 3, and are all distributed at the power interface 311; considering that two corresponding welding points need to be added for each additional structure, in order to reduce the difficulty of installation, the other two limit plates 312 and a fixing plate 313 can be integrally formed on a bottom plate, that is, the fixing plate 313 and the two limit plates 312 are integrally formed, thereby reducing the number of welding points and reducing the difficulty of installation.

[0057] Reference Figures 8 to 10 Specifically, in the present invention, the base 11 is hollow, and the upper end surface of the base 11 is formed with an installation cabin 113 for placing the condenser 4. Therefore, the condenser 4 can be directly integrated with the base 11, so that the base 11 can accommodate the condenser 4 while providing support and bearing for the overall structure, thereby reducing the actual occupied space of the overall structure, improving the integration, and facilitating the miniaturization design of the drinking water equipment.

[0058] The condenser 4 includes a receiving seat 41 and a microchannel condenser 424. The microchannel condenser 424 includes at least one microchannel flow tube 421. The microchannel flow tube 421 is a pipeline containing multiple microchannels inside, which can increase the pipeline area through which the liquid medium flows, that is, increase the contact area between the liquid medium and the pipeline, and improve the heat dissipation effect of the liquid medium; specifically, a plurality of parallel microchannels are formed in the microchannel flow tube 421. In the utility model, the microchannel flow tube 421 is in the shape of a flat tube, and the number of microchannels is 6, 8 or 9, which can be adjusted according to different refrigerant flow rates and the power of the compressor 3; it should be noted that the number of microchannels is not limited to the above number, and can also be 5, 7 and 10, etc. The number of microchannels can be adjusted according to actual design requirements and usage requirements; in addition, the shape of the microchannel flow tube 421 can also be changed according to actual design requirements and usage requirements, such as L-type.

[0059] Reference Figures 8 to 10 , the accommodating seat 41 provides support for the microchannel condenser 424, and the accommodating seat 41 can be detachably installed in the installation cabin 113, so that the condenser 4 can be repaired or replaced later by removing the accommodating seat 41; the accommodating seat 41 is formed with a mounting groove 411, and the mounting groove 411 is used to install the microchannel condenser 424, that is, the setting of the mounting groove 411 provides space for the microchannel condenser 424, further improving the integration of the overall structure. The microchannel condenser 424 also includes two connecting pipes 422, and the two ends of the microchannel flow tube 421 are respectively connected to the two connecting pipes 422. After the refrigerant is compressed by the compressor 3, it flows into the microchannel flow tube 421 through one connecting pipe 422, and then after the heat is dissipated through the microchannel flow tube 421, it enters the evaporator 5 through the other connecting pipe 422; it should be noted that the pipe openings of the two connecting pipes 422 are in the same direction. Since the compressor 3 and the evaporator 5 are both arranged above the condenser 4, the pipe openings of the two connecting pipes 422 are both arranged upward. , thereby reducing the length of the pipeline in the overall structure and further improving the integration of the overall structure; and in order to extend the length of the microchannel flow tube 421 as much as possible, the installation groove 411 can be made rectangular first, and then the two connecting tubes 422 can be respectively placed on two of the four vertices of the bottom of the installation groove 411, thereby combining the connection line between the two connecting tubes 422 to be parallel to a groove wall of the installation groove 411, or the connection line between the two connecting tubes 422 is parallel to the diagonal line of the bottom of the installation groove 411, thereby extending the length of the microchannel flow tube 421.

[0060] Reference Figures 8 to 10In order to improve the heat dissipation effect of the microchannel flow tube 421, the microchannel flow tube 421 is serpentinely arranged in the installation groove 411, thereby increasing the actual length of the microchannel flow tube 421 in disguised form, and further improving the heat exchange efficiency between the refrigerant in the microchannel flow tube 421 and the outside world. Correspondingly, the serpentine setting of the microchannel flow tube 421 is specifically as follows: the mounting groove 411 is rectangular, so the mounting groove 411 has four groove walls, and the planes where two adjacent groove walls are located are perpendicular to each other; therefore, from the length direction of the microchannel flow tube 421, one end of the microchannel flow tube 421 first starts from a connecting tube 422, and then extends in a direction parallel to a groove wall and perpendicular to the adjacent groove wall of this groove wall, and when it reaches the groove wall perpendicular to its length direction, it bends 180° to extend in the opposite direction, and when it reaches the other groove wall, it bends 180° again to extend, and repeats the cycle until it is connected with another connecting tube 422; the above-mentioned setting can extend the length of the microchannel flow tube 421 as much as possible, thereby further improving the heat dissipation efficiency of the microchannel flow tube 421; in addition, the distance between the tube walls of the microchannel flow tube 421 can be made as close as possible without interfering with each other, so that the length of the microchannel flow tube 421 in the mounting groove 411 can be maximized.

[0061] It should be noted that when there are more than two microchannel flow tubes 421, the above method can be used in the same way, that is, the depth of the mounting groove 411 is increased so that multiple microchannel flow tubes 421 are arranged side by side; of course, multiple microchannel flow tubes 421 can also be arranged side by side, that is, multiple microchannel flow tubes 421 are as close as possible, and only one microchannel flow tube 421 is in contact with the groove wall of the mounting groove 411 each time it is bent.

[0062] Another arrangement of the microchannel flow tube 421 can also achieve heat dissipation, that is, directly connecting the microchannel flow tube 421 to the two connecting tubes 422; it should be noted that the microchannel flow tube 421 at this time does not bend 180°, that is, the microchannel flow tube 421 has a portion parallel to a groove wall of the installation groove 411 or parallel to the diagonal line of the groove bottom of the installation groove 411, and this portion accounts for no less than 50% of the length of the microchannel flow tube 421; in other words, most of the microchannel flow tube 421 is parallel to a groove wall of the installation groove 411 or the diagonal line of the groove bottom of the installation groove 411, so that the maximum length of the microchannel flow tube 421 under this arrangement. It should be noted that the above arrangement is more suitable for the design requirements of multiple microchannel flow tubes 421, and when there are multiple microchannel flow tubes 421, some of the microchannel flow tubes 421 can be bent less than 180° to further increase the length of the microchannel flow tube 421.

[0063] In order to further improve the heat dissipation efficiency of the microchannel flow tube 421, a heat sink 43 is provided between two adjacent microchannel flow tubes 421, or a heat sink 43 is provided between adjacent tube walls of the microchannel flow tube 421. The heat sink 43 is also called a fin. When heat is transferred to the heat sink 43 via the microchannel flow tube 421, the heat sink 43 has a larger surface area, thereby effectively improving the efficiency of heat dissipation to the external environment. It should be noted that, generally speaking, in order to ensure the heat dissipation effect, the microchannel flow tube 421, the receiving seat 41 and the heat sink 43 are all made of heat-conducting metal materials, such as aluminum, which can further improve The heat dissipation efficiency of the microchannel flow tube 421; in addition, the use of metal materials for the above-mentioned components also facilitates the assembly and fixation of the various components. For example, the microchannel flow tube 421 is welded in the mounting groove 411, and the welding between the microchannel flow tube 421 and the mounting groove 411 can further enhance the heat dissipation effect of the microchannel flow tube 421, and further improve the heat dissipation efficiency of the microchannel flow tube 421; in the utility model, there are multiple heat sinks 43, that is, multiple heat sinks 43 are arranged between two adjacent microchannel flow tubes 421 or between adjacent tube walls of the microchannel flow tube 421, so as to further improve the heat dissipation effect of the microchannel flow tube 421.

[0064] It should be emphasized that, based on the above idea, a heat sink 43 can also be welded between the outer tube wall of the microchannel flow tube 421 and the groove wall of the mounting groove 411, so as to further increase the overall heat dissipation area of ​​the condenser 4 to obtain a better heat dissipation effect; but considering that the gap between the outer wall of the microchannel flow tube 421 and the mounting groove 411 is relatively narrow, which is not conducive to the subsequent welding operation, a connecting piece 44 can be set in advance, and now a plurality of heat sinks 43 are welded between the connecting piece 44 and the tube wall of the microchannel flow tube 421, and then the entire microchannel condenser 424 is placed in the mounting groove 411 together with the connecting piece 44, and then the connecting piece 44 and the groove wall of the mounting groove 411 are welded; the setting of the connecting piece 44 can reduce the difficulty of installing the heat sink 43 between the groove wall of the mounting groove 411 and the microchannel flow tube 421, and improve the simplicity of the overall structure during assembly.

[0065] Reference Figures 8 to 10Specifically, in order to fix the accommodating seat 41 in the installation chamber 113, the accommodating seat 41 is extended relative to the album to form a connecting portion 412, and the connecting portion 412 is detachably connected to the base 11; in the utility model, the connecting portion 412 and the base 11 can be fixed by bolts, for example, a mounting hole 413 is provided on the connecting portion 412, and a connecting groove 112 is provided on the base 11, and the length direction of the connecting groove 112 is parallel to the length direction of the connecting portion 412. When it is necessary to fix the accommodating seat 41, an expansion bolt can be used to pass through the fixing hole and fit into the connecting groove 112 to complete the fixing of the accommodating seat 41, and other interference fit methods can also be used. The fixing holes and the connecting grooves 112 are used to fix the receiving seat 41. It should be noted that the pipelines for the refrigerant to enter the condenser 4 via the compressor 3 and to enter the evaporator 5 via the condenser 4 are generally made of metal. The length direction of the connecting groove 112 is set parallel to the length direction of the connecting portion 412. The fixing holes and the connecting grooves 112 are matched, so that the receiving seat 41 can fine-tune its position in the installation cabin 113 according to the actual position of the pipeline during the actual installation process, thereby reducing the possibility of stress and damage to the metal pipeline during installation, ensuring the integrity of the overall structure, and from another perspective, reducing the installation difficulty of the installer during the actual installation process.

[0066] Reference Fig.10 and Fig.11 In the utility model, due to the hollow setting of the base 11, it is possible for the condenser 4 to have upper and lower air convection, and the air convection at the condenser 4 can greatly improve the condensation effect of the condenser 4 on the refrigerant; in order to promote the occurrence of air convection at the condenser 4, an air outlet 414 can be opened at the bottom of the accommodating seat 41 to promote the generation of air convection.

[0067] Based on the above ideas, in order to keep the air at the condenser 4 flowing to improve the cooling effect of the condenser 4 on the refrigerant, a fan 6 can be arranged inside the base 11. The arrangement of the fan 6 will force the air at the condenser 4 to flow, thereby further improving the overall condensation effect of the condenser 4 on the refrigerant; it is necessary to discuss that the fan 6 includes a fan 6 body, which can be made to blow air upward, that is, the wind generated by the fan 6 body blows toward the bottom of the compressor 3, which will make the air flow rate at the condenser 4 reach the maximum, but because the condenser 4 will emit heat, and the compressor 3 is arranged above the condenser 4, the refrigerant at the bottom of the compressor 3 may absorb heat, thereby causing the power of the compressor 3 to decrease; and if the fan 6 blows in a direction away from the compressor 3, a stable air flow can be generated at the condenser 4. Although the air flow rate is lower than that of the aforementioned method, the heat emitted by the condenser 4 will be blown away, reducing the probability of ineffective heat absorption of the refrigerant in the compressor 3.

[0068] In order to install the fan 6, a fan 6 compartment 111 is opened on one side wall of the base 11, that is, the fan 6 as a whole can slide in the fan 6 compartment 111 similar to a drawer; the cooperation between the fan 6 and the fan 6 compartment 111 makes the installation of the fan 6 as a whole simpler, and further improves the simplicity of the overall structure during assembly; in addition, the pull-out method also facilitates the subsequent inspection or replacement of the fan 6; for example, drinking water equipment generally reserves one or more inspection ports, and the fan 6 compartment 111 can be directed to a certain inspection port, so that when the cooling effect of the drinking water equipment is not good or there is a problem, the inspection port can be used to directly check whether the fan 6 is faulty; and thus the pull-out setting is not only convenient for installation, but also for subsequent maintenance.

[0069] Specifically, the fan 6 includes a fan 6 body and a mounting base 61. The two ends of a side wall of the mounting base 61 extend relatively along its length direction to form a limiting portion 611. The limiting portion 611 can fix the fan 6 on the base 11; in the utility model, a first fixing hole 612 is provided on the limiting portion 611, and a second fixing hole 111b corresponding to the first fixing hole 612 is formed on the base 11, so that a bolt can be used to pass through the first fixing hole 612 and be threadedly connected with the second fixing hole 111b, thereby completing the fixation of the fan 6.

[0070] Reference Fig.10 and Fig.11 It should be noted that a through hole 613 compatible with the air outlet 414 is also provided on the mounting base 61 of the fan 6, thereby avoiding the possibility that the mounting base 61 interferes with the air flow; in addition, the mounting base 61 can be fixed in other ways; for example, the first fixing hole 612 is changed into a buckle, and the second fixing hole 111b is changed into a slot, so that the mounting base 61 can be fixed in the fan 6 compartment 111 by using the combination of the buckle and the slot; of course, the fan 6 can also be fixed to the base 11 in other ways, which can be flexibly used according to specific design requirements.

[0071] In the utility model, the fan 6 body is installed in the mounting base 61, and the mounting base 61 can provide support and protection for the fan 6 body; specifically, the fan 6 body has a shell 621, and the shell 621 is fixedly arranged in the mounting base 61, that is, the mounting base 61 is covered on the shell 621 and fixedly connected to the shell 621; and in order to supply power to the fan 6 body, a wire hole 614 is opened on the mounting base 61, and a wire channel 622 is provided on the shell 621 of the fan 6 body, and the wire can pass through the wire hole 614 and the wire channel 622 to supply power to the fan 6 body; the setting of the wire hole 614 and the wire channel 622 provides an accommodation space for the routing of the wires, further improving the integration of the overall structure.

[0072] Since the base 11 is hollow, the fan 6 compartment 111 alone cannot support the entire fan 6, so a number of hanging arms are also provided in the base 11, and the hanging arms are used to support the mounting seat 61; in the utility model, two groups of hanging arms are symmetrically arranged inside the base 11, and each group has 3 hanging arms; the hanging arms include a connecting arm 114a and a bearing arm, one end of the connecting arm 114a is fixed to the base 11, and the bearing arm is arranged on the other end of the main body, and the length direction of the connecting arm 114a is perpendicular to the length direction of the bearing arm. It can be generally understood that when observed along the pulling direction of the fan 6, the connecting arm 114a and the bearing arm are L-shaped, that is, when the fan 6 is placed in the base 11, the connecting arm 114a will cooperate with the outer side wall of the mounting seat 61 to block the displacement of the mounting seat 61 in the left and right directions, and the bearing arm will support the mounting seat 61, thereby supporting the entire fan 6.

[0073] Reference Fig.10 and Fig.11 In the present invention, the hanging arms belonging to the same group are distributed in a straight line in the base 11, and the two hanging arms far away from each other are respectively connected to the opposite side walls in the base 11; it should be pointed out that the base 11 can be made of metal material or plastic integrally formed, and the connection between the hanging arm and the inner wall of the base 11 here means that the two are connected together during molding; in order to improve the structural strength of the hanging arm, a reinforcing rib 114c can be provided on the side of the hanging arm away from the mounting seat 61; in the present invention, the hanging arm located in the middle of the hanging arms belonging to the same group is provided with two reinforcing ribs 114c, and the other two hanging arms are each provided with a reinforcing rib 114c. The number and specific design position of the reinforcing ribs 114c can be determined according to the actual weight and design requirements of the fan 6, and the present invention will not repeat them again.

[0074] In summary, in the present invention, the condenser 4 and the base 11 are actually integrated into one, thereby fully utilizing the volume of the base 11, thereby reducing the volume of the overall structure without affecting the refrigeration effect, which is conducive to the miniaturization of the drinking water equipment.

[0075] Based on the above-mentioned idea of ​​miniaturization of drinking water equipment, in the present invention, in order to match the shape of the base 11, the tank body 2 is roughly square, and the evaporator 5 is sleeved on the tank body, so that the refrigerant in the evaporator 5 can instantly take away the heat of the tank body 2 when evaporating, and in order to ensure the cooling effect of the evaporator 5 on the tank body 2, the insulation box 7 can be wrapped around the outer periphery of the tank body 2 to keep it warm, and the insulation box 7 can be made of insulation materials such as foam sponge; specifically, the bracket 12 is installed on the lower surface of the tank body 2, and the bracket 12 has two legs, and the two legs are respectively Fixed at both ends of the base 11; in summary, the evaporator 5 is sleeved on the outer surface of the tank body 2, and the tank body 2 is installed on the top of the bracket 12, the bottom end of the bracket 12 is installed on the base 11, and the condenser 4 is integrated with the base 11; it should be noted that since the bracket 12 itself has a height, an installation space will be formed between the cold tank module and the condenser 4, so that the compressor 3 can be installed in the installation space; the above-mentioned structural arrangement further improves the integration of the overall structure, thereby facilitating the miniaturization of the drinking water equipment. In addition, in order to further reduce the installation difficulty and installation steps of the overall structure, an installation port 121 for installing the protective cover 32 is opened on the support frame 12, so that the installer can install the protective cover 32 through the installation port 121. The opening of the installation port 121 actually expands the operating space of the installer when installing the protective cover 32, and further facilitates the installation operation of the installer on the protective cover 32.

[0076] From the perspective of the refrigerant flow path, the refrigerant enters the compressor 3 from the air intake port of the compressor 3, and then forms a high-pressure refrigerant after being pressurized by the compressor 3, and the high-pressure refrigerant is in liquid state; then the high-pressure liquid refrigerant flows into the microchannel flow tube 421 in the condenser 4 to dissipate heat, and the high-pressure liquid refrigerant cooled by the condenser 4 will flow into the evaporator 5. The evaporator 5 and the outer surface of the tank body 2 are tightly fitted, so that the high-pressure liquid refrigerant will absorb heat and evaporate after entering the evaporator 5, and will be converted into a low-pressure gaseous refrigerant. Then the low-pressure gaseous refrigerant will flow back into the compressor 3 and be pressurized for circulation, thereby completing the refrigeration.
