Detailed Implementation
[0024] 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.
[0025] Combination Figures 1 to 3 The drinking water device 100 according to an embodiment of the present invention includes: a support 10, the support 10 having a first end 10a and a second end 10b opposite to each other along a first direction, the first end 10a being provided with a first slot 11 facing the second end 10b. The opening of the first slot 11 faces the second end 10b. Exemplarily, the first direction can be the left-right direction of the drinking water device 100, or the front-back direction of the drinking water device 100, etc.
[0026] The drinking water equipment 100 also includes a condenser 20, one end of which is inserted into the first slot 11. Specifically, the drinking water equipment 100 may have a cooling function; the condenser 20 can cool the high-temperature, high-pressure refrigerant, maintain the continuous operation of the refrigeration cycle, and improve cooling efficiency and operational stability. The insertion of one end of the condenser 20 into the first slot 11 facilitates positioning of that end.
[0027] The drinking water equipment 100 also includes a fixing member 30, which is connected to the second end 10b of the bracket 10 and positions the other end of the condenser 20.
[0028] For example, when installing the condenser 20, one end of the condenser 20 can be inserted into the first slot 11 first, and then the other end of the condenser 20 can be fixed by the fastener 30, which improves the installation efficiency of the condenser 20. When it is necessary to disassemble the condenser 20, the fastener 30 can be removed to release the fixation of the condenser 20. Since the condenser 20 is inserted into the first slot 11, no additional disassembly action is required to remove the condenser 20, which facilitates the maintenance of the condenser 20 in the future.
[0029] According to the embodiment of the present utility model, the drinking water device 100 is provided with a first slot 11 at the first end 10a of the bracket 10 and a fixing member 30 is provided to connect the second end 10b of the bracket 10. One end of the condenser 20 is inserted into the first slot 11, and the other end of the condenser 20 is positioned by the fixing member 30, which facilitates the installation of the condenser 20 and makes it easier for later maintenance.
[0030] The fastener 30 is connected to the second end 10b. The fastener 30 and the second end 10b can be connected together by means of snap-fit connection, screw connection or bolt and nut combination connection. Of course, the fastener 30 and the second end 10b can also be connected together by means of welding, riveting or other means. This application does not limit the connection method between the fastener 30 and the second end 10b of the bracket 10.
[0031] Combination Figure 3 In some embodiments of this utility model, the bracket 10 includes a base plate 12 and a surrounding plate 13. The surrounding plate 13 is connected to the base plate 12 and surrounds an installation space above the base plate 12. At least a portion of the condenser 20 is disposed in the installation space. Specifically, the entire condenser 20 may be disposed in the installation space; or a portion of the condenser 20 may be disposed in the installation space, with the other portion extending out of the installation space. The base plate 12 supports the condenser 20, improving its structural stability. Furthermore, the surrounding plate 13, connected to the base plate 12 and surrounding the installation space, protects the condenser 20. By combining the base plate 12 and the surrounding plate 13, the structural stability of the condenser 20 after installation is improved.
[0032] Combination Figure 2 and Figure 3In some embodiments of this utility model, the enclosure 13 includes a first side plate 131 and a second side plate 132. The first side plate 131 is located at the first end 10a, and the second side plate 132 is located at the second end 10b. A first slot 11 is located inside the first side plate 131, with its opening facing the second side plate 132. The upper edge of the second side plate 132 has a clearance notch 1321, which is opposite to the condenser 20 along a first direction. Specifically, during the insertion of one end of the condenser 20 into the first slot 11, the clearance notch 1321 on the upper edge of the second side plate 132 can make way for the condenser 20, facilitating its rapid assembly into the installation space and improving the installation efficiency of the condenser 20. In addition, the first slot 11 is located inside the first side plate 131, which protects the first slot 11, thereby protecting the condenser 20 and improving its structural stability.
[0033] The fastener 30 is stacked and connected to the second side plate 132 along the first direction. In other words, the connection between the fastener 30 and the second side plate 132 along the first direction can improve the connection stability between the fastener 30 and the bracket 10, thereby facilitating the stable positioning of the condenser 20 by the cooperation of the fastener 30 and the bracket 10.
[0034] Combination Figure 3 In some embodiments of this utility model, the condenser 20 includes a main body 21 and a manifold 22, with the manifold 22 connected to the main body 21. The main body 21 is primarily used for heat release, and the refrigerant flows within it, facilitating heat exchange between the refrigerant and the surrounding environment and maintaining the stability of the refrigeration system. The manifold 22 is primarily used for refrigerant collection. Exemplarily, the manifold 22 may include an inlet manifold and an outlet manifold. The refrigerant first enters the main body 21 through the inlet manifold and then exits the condenser 20 through the outlet manifold. Figure 2 The lower edge of the clearance notch 1321 is provided with a clearance groove 1322. The clearance groove 1322 is opposite to the manifold 22 along the first direction. The clearance groove 1322 can make way for the manifold 22 during the installation of the condenser 20, so that the manifold 22 can be quickly installed into the installation space, thereby improving the installation efficiency of the condenser 20.
[0035] Optionally, the bracket 10 includes a base plate 12 and a surrounding plate 13. The surrounding plate 13 is connected to the base plate 12 and surrounds an installation space above the base plate 12. At least a portion of the condenser 20 is disposed in the installation space. The bracket 10 may also be provided with a water collection tank, which is connected to the base plate 12 and protrudes from the base plate 12 on the side away from the installation space. The manifold 22 is opposite to the water collection tank in the vertical direction. The condensate generated by the refrigeration system during operation flows into the water collection tank under the action of gravity. In conjunction with the above, the manifold 22 is used for the collection of refrigerant. Therefore, the refrigerant in the manifold 22 is relatively concentrated and has a higher temperature. Thus, the condensate in the water collection tank can be heated by the manifold 22, improving the evaporation efficiency of the condensate and preventing condensate overflow or leakage.
[0036] Combination Figure 1 and Figure 3 In some embodiments of this utility model, the base plate 12 is provided with a vent 121, which is opposite to the condenser 20. The drinking water device 100 also includes a cooling fan 40, which is opposite to the vent 121. The cooling fan 40 is used to drive airflow through the condenser 20, increase the airflow speed around the condenser 20, improve the heat dissipation efficiency of the condenser 20, and improve the reliability of the drinking water device 100.
[0037] For example, the vent 121 is opposite to the condenser 20 in the vertical direction, and the cooling fan 40 is located at the bottom of the water drinking device 100, which optimizes the layout of the water drinking device 100, makes the structure of the water drinking device 100 compact, and facilitates the dissipation of heat from the condenser 20 to the outside of the water drinking device 100.
[0038] Furthermore, the vent 121 is provided with annular ribs 122 around its perimeter. The annular ribs 122 are located inside the enclosure 13. A condensate trough 14 is provided between the annular ribs 122 and the enclosure 13. Specifically, during the cooling process of the drinking water equipment 100, the cooling system may generate condensate. By setting the annular ribs 122 in conjunction with the enclosure 13, the condensate is collected in the condensate trough 14 to prevent condensate leakage.
[0039] Combination Figure 2 In some embodiments of this utility model, the fixing member 30 is stacked and connected to the bracket 10 along the first direction. That is, the surface-to-surface connection between the fixing member 30 and the bracket 10 along the first direction can improve the connection stability between the fixing member 30 and the bracket 10, thereby facilitating the stable positioning of the condenser 20 by the cooperation of the fixing member 30 and the bracket 10.
[0040] Combination Figure 4In some embodiments of this utility model, the bracket 10 is provided with a first positioning hole 15, the fixing member 30 is provided with a second positioning hole 31, and the drinking water device 100 also includes a positioning bolt. The positioning bolt passes through the first positioning hole 15 and the second positioning hole 31 along a first direction. By setting the positioning bolt to lock the fixing member 30 and the bracket 10 along the first direction, it is convenient for the installation and maintenance of the condenser 20. When installing the condenser 20, one end of the condenser 20 can be inserted into the first slot 11 first, and then the fixing member 30 and the bracket 10 can be locked by the positioning bolt to fix the condenser 20. For example, only one positioning bolt is needed to fix the condenser 20, which simplifies the installation structure of the condenser 20 and improves the installation efficiency. In addition, when it is necessary to repair the condenser 20, it is only necessary to unlock the positioning bolt to release the locking of the fixing member 30 and the bracket 10 to separate the condenser 20 from the bracket 10, which simplifies the disassembly steps of the condenser 20 and improves the maintenance efficiency.
[0041] Combination Figure 4 In some embodiments of this utility model, the bracket 10 is provided with a positioning groove 16, and the fixing member 30 is provided with a positioning post 32, which is inserted into the positioning groove 16 along a first direction. Specifically, when the fixing member 30 is connected to the bracket 10, the positioning post 32 of the fixing member 30 is inserted into the positioning groove 16, which facilitates the pre-positioning of the fixing member 30 and improves the fixing efficiency between the fixing member 30 and the bracket 10.
[0042] In some embodiments of this utility model, the bracket 10 is provided with a first positioning hole 15, the fixing member 30 is provided with a second positioning hole 31, and the drinking water device 100 also includes a positioning bolt. The positioning bolt passes through the first positioning hole 15 and the second positioning hole 31 along a first direction. The bracket 10 is provided with a positioning groove 16, and the fixing member 30 is provided with a positioning post 32. The positioning post 32 is inserted into the positioning groove 16 along the first direction. Specifically, when the fixing member 30 is connected to the bracket 10, the positioning post 32 of the fixing member 30 can be inserted into the positioning groove 16 first to facilitate the pre-positioning of the fixing member 30. Then, the positioning bolt passes through the first positioning hole 15 and the second positioning hole 31 along the first direction to enable the positioning bolt to quickly lock the fixing member 30 and the bracket 10, thereby improving the installation efficiency of the condenser 20.
[0043] The positioning post 32 may include two, the positioning groove 16 may include two, the first positioning hole 15 may be located between the two positioning grooves 16, and the second positioning hole 31 may be located between the two positioning posts 32, thereby improving the connection efficiency and stability between the fixing member 30 and the bracket 10.
[0044] Combination Figure 5In some embodiments of this utility model, the drinking water device 100 further includes: a housing 50, which includes a housing body 51 and a side panel 52. The housing body 51 has an installation port 511 on one side along a first direction. The side panel 52 is detachably connected to the housing body 51 to open and close the installation port 511. The bracket 10, the condenser 20, and the fixing member 30 are disposed inside the housing 50, and the fixing member 30 and the side panel 52 are distributed opposite to each other along the first direction. Specifically, the housing 50 can protect the components of the drinking water device 100 and provide a stable working environment for the components of the drinking water device 100. When it is necessary to inspect or repair the condenser 20, the side panel 52 can be detached to open the installation port 511. The fixing member 30 and the side panel 52 are opposite to each other along the first direction and are combined... Figure 5 As shown, the fastener 30 is closer to the side panel 52 than the first slot 11. Therefore, after removing the side panel 52, the fastener 30 can be easily removed to release the fixation of the condenser 20, making it easier to remove the condenser 20 and improving the maintenance efficiency of the condenser 20.
[0045] Combination Figure 3 and Figure 4 In some embodiments of this utility model, the fixing member 30 is provided with a second slot 34 for fixing the water pipe. Specifically, the water pipe can be connected to the water inlet and water outlet of the drinking water device 100. By fixing the water pipe with the second slot 34 in the fixing member 30, the layout of the water pipe of the whole machine is optimized, and the fixing member 30 can simultaneously position the condenser 20 and the water pipe, simplifying the components of the drinking water device 100.
[0046] For example, the drinking water device 100 may be provided with a pure water inlet pipe, a domestic water inlet pipe, a drain pipe, etc., wherein the second slot 34 can be used to fix at least one of the water pipes in the inlet pipe and the outlet pipe.
[0047] Combination Figure 4 and Figure 5 In some embodiments of this utility model, the second slot 34 is provided on the side of the fixing member 30 away from the condenser 20 along the first direction, so as to avoid the water pipe from contacting the high-temperature condenser 20, compressor and other components, and improve the service life of the water pipe.
[0048] Combination Figure 3In some embodiments of this utility model, the second slot 34 includes a plurality of slots arranged along a third direction. The opening directions of adjacent second slots 34 are opposite to each other along the second direction, and the first direction, the second direction, and the third direction are perpendicular to each other. By arranging a plurality of second slots 34 along the second direction, it is convenient to position different water pipes through the second slots 34, and it is also convenient to optimize the water pipe layout of the drinking water device 100. In addition, the openings of adjacent second slots 34 are opposite to each other along the second direction, making the structure of the fixing member 30 compact and capable of positioning multiple water pipes. For example, the first direction can be the left-right direction of the drinking water device 100, the second direction can be the up-down direction of the drinking water device 100, and the third direction can be the front-back direction of the drinking water device 100.
