[0042] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0043] See also Figure 1 , 2The embodiment of the present invention provides a cold drink machine, comprising a chassis 1, a partition substrate 2 arranged in the chassis 1, a cold drink device for forming cold drinks, and a compressor 3 for refrigerating the cold drink device, wherein the chassis 1 is partitioned into an upper equipment space and a lower equipment space by the partition substrate 2, and the cold drink device and the compressor 3 are respectively arranged in the upper equipment space and the lower equipment space;

[0044] The cold drink device comprises an evaporator 4, a cold drink tank 5 disposed in the evaporator 4, a stirring member 51 disposed in the cold drink tank 5, and a driving device 6 for driving the stirring member 51;

[0045] The front or top of the chassis 1 is provided with a display area, and the top of the chassis is provided with a feeding area;

[0046] In the display area, the front or top of the chassis 1 is tilted upward to form a display space 1a for installing a display screen device in the chassis 1, and a display port 11a for installing a display panel is opened in the display area; such a configuration allows the display panel installed in the display port 11a to face the user's field of vision during user operation, thereby facilitating the operation and viewing of the display panel.

[0047] At the feeding area, the top of the chassis 1 is concave to form a feeding trough 1b, and a detachable feeding hopper 1c is provided in the feeding trough 1b, and the feeding hopper 1c is connected to the cold drink can 5.

[0048] Specifically, the upper equipment space is divided into a refrigeration space 1d and a driving heat dissipation space 1e on the left and right, and the evaporator 4 and the driving device 6 are respectively placed in the refrigeration space 1d and the driving heat dissipation space 1e;

[0049] On the chassis 1, the upper equipment space is provided with discharge holes 11 adapted to the cold drink can 5 and upper heat dissipation ports 12 for heat dissipation at the left and right ends. Preferably, the upper heat dissipation ports 12 are provided with heat dissipation plates 13, and the heat dissipation plates 13 are provided with a plurality of heat dissipation channels.

[0050] In order to improve the compactness of the structure inside the chassis 1 while ensuring a certain heat dissipation performance, the partition substrate 2 is provided with a connecting area for connecting the upper equipment space and the lower equipment space, and the connecting area is provided with a plurality of connecting holes 21; the connecting area is arranged corresponding to the drive heat dissipation space 1e.

[0051] Moreover, brackets 14 for auxiliary supporting the partition substrate 2 and heat exchange shells 15 for installing heat exchangers are respectively provided on both sides of the lower equipment space; the brackets 14 and the heat exchange shells 15 jointly auxiliary support the partition substrate 2 .

[0052] The heat exchanger 31 of the compressor 3 is arranged in the heat exchange housing 15, and the heat exchange housing 15 is also provided with a cooling fan 151 on the inner side, and the cooling fan 151 is located below the communication area. Correspondingly, the chassis 1 is provided with a lower heat dissipation port corresponding to the heat exchange housing 15, and the lower heat dissipation port is also provided with the heat dissipation plate 13.

[0053] Based on the setting of the connecting hole 21, the cooling fan 151 located below the connecting area will make the air in the upper equipment space flow into the lower equipment space and be discharged from the lower cooling port during the process of exhausting and dissipating heat to the lower cooling port. Therefore, the heat generated in the lower equipment space is difficult to flow into the upper equipment space, and based on the negative pressure, the external air will flow from the upper cooling port 12 into the driving cooling space 1e, thereby cooling the equipment arranged in the driving cooling space 1e. Therefore, the electronic control device can be arranged in the driving cooling space 1e. Therefore, only a single and small-sized cooling fan 151 is required in the chassis 1 to dissipate heat in the upper equipment space and the lower equipment space, thereby providing feasible conditions for the compact design and installation of the structure in the chassis 1.

[0054] In order to facilitate the disassembly of the feed hopper 1c, a connecting pipe 11b connected to the cold drink tank 5 is provided at the bottom of the feed trough 1b; the shape of the feed hopper 1c is adapted to the feed trough 1b to cover the surface of the feed trough 1b;

[0055] The inner side wall of the feed hopper 1c is provided with a lifting edge 11c for hand-lifting, so as to take the feed hopper 1c out of the feed trough 1b.

[0056] See also Figure 3-8 The driving device 6 includes a rotating shaft 61 for driving the stirring member 51 to rotate and a first sealing connection seat 62.

[0057] The evaporator 4 is provided with a heat preservation shell 41, and a first mounting hole 411 is provided on a side wall of the heat preservation shell 41. The cold drink can 5 is installed inside the heat preservation shell 41, and a second mounting hole 52 is formed on the cold drink can 5. The second mounting hole 52 and the first mounting hole 411 are rotatably penetrated by the rotating shaft 61. The first sealing connection seat 62 is connected between the heat preservation shell 41 and the cold drink can 5. The first sealing connection seat 62 is connected to a limiting member 621, and the limiting member 621 is inserted in the second mounting hole 52, and the limiting member 621 is sealed and connected to the second mounting hole 52. The rotating shaft 61 is penetrated by the limiting member 621, and a first sealing member 63 is provided between the rotating shaft 61 and the limiting member 621. The inner ring of the first sealing member 63 is sealed and connected to the rotating shaft 61, and a clearance fit is formed between the outer ring of the first sealing member 63 and the limiting member 621.

[0058] Since a clearance fit is formed between the outer ring of the first seal 63 and the limiter 621, when the rotating shaft 61 rotates, the rotating shaft 61 can form a dynamic sealing connection with the first sealing connection seat 62 and the limiter 621 through the first seal 63, so as to reduce the amount of wear on the first seal 63 caused by the wear of the rotating shaft 61, extend the service life of the first seal 63, and ensure the sealing performance between the rotating shaft 61 and the first sealing connection seat 62, thereby effectively reducing the risk of liquid water leakage in the cold drink tank 5 and ensuring the liquid water ice making rate of the cold drink machine.

[0059] It should be noted that the first sealing member 63 is preferably made of a wear-resistant and corrosion-resistant material such as PTFE or rubber to ensure that the first sealing member 63 can be used for a long time without being worn or corroded.

[0060] In this embodiment, the first sealing connection seat 62 can be assembled in the second mounting hole 52 of the cold drink can 5 by the limiting member 621, and the sealing connection between the limiting member 621 and the side wall of the second mounting hole 52 is used to ensure the sealing performance between the first sealing connection seat 62 and the cold drink can 5.

[0061] To ensure the sealing fit between the stopper 621 and the second mounting hole 52, as shown in FIG. Figures 3 to 5 As shown, an extension boss 622 is formed at one end of the stopper 621 inserted into the second mounting hole 52, and the outer ring of the extension boss 622 is sealed and abutted against the inner side wall of the cold drink can 5 through a sealing gasket 623, and the inner ring of the extension boss 622 is connected to the outer ring of the first sealing member 63, so as to ensure that the stopper 621 limits the first sealing member 63 and assembles it on the rotating shaft 61. The sealing gasket 623 can be deformed when under pressure, and adaptively fill the gap between the connecting surfaces, so that the sealing gasket 623 is used to adapt to the abutment gap between the extension boss 622 of the stopper 621 and the inner side wall of the cold drink can 5, so as to achieve a sealed contact between the stopper 621 and the inner wall surface of the cold drink can 5, so as to prevent the liquid in the cold drink can 5 from leaking from the abutment position between the stopper 621 and the inner wall surface of the cold drink can 5, and further reduce the risk of liquid water leakage in the cold drink can 5.

[0062] Optionally, the limit member 621 is made of elastic material such as rubber. When the limit member 621 is inserted into the second mounting hole 52, the side wall of the limit member 621 rebounds and tightly abuts against the side wall surface of the second mounting hole 52 to further enhance the sealing performance between the limit member 621 and the cold drink can 5.

[0063] Of course, the stopper 621 is not limited to elastic materials such as rubber, but can also be made of hard materials. When the stopper 621 is made of hard materials, the stopper 621 and the first sealing connection seat 62 are detachably connected to ensure the convenience of assembly between the stopper 621 and the first sealing connection seat 62.

[0064] Specifically, Figure 3 and Figure 5 As shown, the limiting member 621 is formed with a connecting column 611, and a plurality of threaded holes are arranged at intervals in the connecting column 611. The first sealing connecting seat 62 is formed with a plurality of connecting holes. When the first sealing connecting seat 62 and the limiting member 621 are assembled on the cold drink can 5, the connecting column 611 of the limiting member 621 can be passed through the second mounting hole 52, and the first sealing connecting seat 62 is connected to the limiting member 621 by bolts or studs, thereby ensuring the convenience of assembly between the limiting member 621 and the first sealing connecting seat 62.

[0065] Furthermore, a second seal 64 is provided on the side of the first seal 63 facing away from the cold drink can 5, the inner ring of the second seal 64 is sealed and connected to the rotating shaft 61, and the outer ring of the second seal 64 abuts against the limit member 621, so that the second seal 64 can be used to further reduce the connection gap between the limit member 621 and the rotating shaft 61, thereby further enhancing the sealing performance between the rotating shaft 61 and the limit member 621.

[0066] Specifically, the inner ring of the second seal 64 is formed with a sealing lip surface, and the cross-section of the sealing lip surface is an inclined surface, so that an oil seal is formed between the rotating shaft 61 and the limit member 621 and the first sealing connecting seat 62 through the second seal 64, thereby utilizing the second seal 64 to cooperate with the first seal 63 to provide stable and reliable sealing performance for the rotating shaft 61 and the limit member 621 and the first sealing connecting seat 62.

[0067] In this embodiment, in order to ensure the installation stability of the first sealing connection seat 62, the first sealing connection seat 62 forms a preset height, and the distance between the inner side surface of the heat-insulating shell 41 and the outer side surface of the cold drink can 5 is equal to the preset height. When the first sealing connection seat 62 is assembled between the heat-insulating shell 41 and the cold drink can 5, the first sealing connection seat 62 can be clamped and fixed by the inner side surface of the heat-insulating shell 41 and the outer wall surface of the cold drink can 5, and the first sealing connection seat 62 is connected with the stopper 621 penetrating the second mounting hole 52, so as to ensure the assembly stability of the first sealing connection seat 62 between the heat-insulating shell 41 and the cold drink can 5, and avoid the first sealing connection seat 62 from shaking and affecting the sealing performance of the first sealing member 63.

[0068] In this embodiment, Figures 2 to 5 As shown, the driving device 6 further includes a second sealing connection seat 65, which is disposed on the outer side wall of the heat-insulating outer shell 41, and the second sealing connection seat 65 is detachably connected to the first sealing connection seat 62, and the size of the second sealing connection seat 65 is larger than the size of the first mounting hole 411. Furthermore, when the second sealing connection seat 65 is connected to the outer side wall of the heat-insulating outer shell 41, the second sealing connection seat 65 can shield the first mounting hole 411, thereby preventing the internal components of the heat-insulating outer shell 41 from being exposed, and realizing dust prevention of the heat-insulating outer shell 41.

[0069] It should be noted that in order to detachably connect the first sealing connection seat 62 and the second sealing connection seat 65, the first sealing connection seat 62 and the second sealing connection seat 65 are connected to form an integral sealing device, a connecting boss 625 is formed on the side of the first sealing connection seat 62 facing away from the cold drink can 5, and a connecting hole is formed on the second sealing connection seat 65. When assembling the first sealing connection seat 62 and the second sealing connection seat 65, the connecting boss 625 of the first sealing connection seat 62 passes through the mounting hole of the side wall of the thermal insulation outer shell 41, and the first sealing connection seat 62 and the second sealing connection seat 65 are threadedly connected using bolts or studs.

[0070] Furthermore, if Figures 3 to 5 As shown, a sealing boss 651 is formed on the side of the second sealing connection seat 65 facing the first sealing connection seat 62, and the first sealing connection seat 62 is formed with a plug-in hole 624. The sealing boss 651 is inserted into the plug-in hole 624, and the inner side of the sealing boss 651 abuts against the second sealing member 64, so as to utilize the sealing contact between the inner side surface of the sealing boss 651 and the second sealing member 64, so that the connection position of the first sealing connection seat 623 and the second sealing connection seat 65 forms a sealed connection, and the second sealing member 64 is axially limited, further ensuring the sealing performance of the second sealing member 64 to the first sealing connection seat 62 and the second sealing connection seat 65.

[0071] It should be noted that, in the present embodiment, the plug-in hole 624 is coaxial with the first mounting hole 411 and the second mounting hole 52, the sealing boss 651 forms a hollow hole, and the rotating shaft 61 is rotatably connected to the hollow hole, so as to utilize the sealing boss 651 of the second sealing connection seat 65 to limit and protect the rotating shaft 61, thereby further ensuring the rotation stability of the rotating shaft 61.

[0072] Among them, Figure 6 As shown, the outer wall of the thermal insulation shell 41 is formed with a first mounting groove 412, and the second sealing connection seat 65 is embedded in the first mounting groove 412, so that the outer wall of the second sealing connection seat 65 is limited and fixed by the first mounting groove 412, further ensuring the stability of the second sealing connection seat 65 set in the thermal insulation shell 41.

[0073] In the embodiment of the present invention, Figure 1 and Figure 2As shown, the driving device 6 also includes a driving connection seat 66, one side of which is connected to the second sealing connection seat 65, and the other side of the driving connection seat 66 is connected to the driving member 7. A transmission group (not shown in the figure) is arranged inside the driving connection seat 66, and the output shaft of the driving member 7 is rotatably connected to the active end of the transmission group, and the driven end of the transmission group is rotatably connected to the rotating shaft 61. Then, the driving member 7 can be used to drive the active end of the transmission group to rotate, and the driven end of the transmission group and the rotating shaft 61 can be driven to rotate, so that the rotating shaft 61 can drive the stirring structure inside the cold drink can 5 to rotate, so as to realize the transmission of ice cubes in the cold drink can 5.

[0074] By driving the connecting seat 66 to provide dust-proof protection for the transmission group, as well as the connecting parts between the transmission group and the driving member 7 and the rotating shaft 61, the driving member 7, the transmission group and the rotating shaft 61 can be prevented from being directly exposed to the external environment, thereby ensuring effective transmission between the driving member 7, the transmission group and the rotating shaft 61 and ensuring the energy utilization rate of the driving member 7.

[0075] It should be noted that the drive connection seat 66 may include a first connection seat and a second connection seat that are detachably connected, so as to perform maintenance and repair on the transmission group inside the drive connection seat 66. The first connection seat is connected to the housing of the drive motor, and the second connection seat is connected to the second sealing connection seat 65. The front end of the rotating shaft 61 is rotatably connected to the second connection seat through a bearing to further ensure the rotation stability of the rotating shaft 61.

[0076] It should also be noted that the transmission group preferably uses a gear group to transmit the drive member 7 and the rotating shaft 61 to reduce the space occupied by the drive connection seat 66 and improve the space utilization rate of the material processing shell sealing connection component. Of course, the specific structure of the transmission group is not limited to the gear group, and can also be other transmission structures such as chain drive or belt drive. The specific transmission structure of the transmission group can be set accordingly according to actual conditions.

[0077] Among them, Figure 2 As shown, a second mounting groove 652 is formed on the side of the second sealing connection seat 65 facing away from the heat preservation shell 41, and one of the side surfaces of the driving connection seat 66 is embedded in the second mounting groove 652, so as to limit and fix the side surface of the second sealing connection seat 65 through the second mounting groove 652, thereby ensuring the connection stability between the second sealing connection seat 65 and the driving connection seat 66.

[0078] It should be noted that in order to further ensure the connection stability between the drive connection seat 66 and the second sealing connection seat 65, a plurality of threaded countersunk holes are formed in the second mounting groove 651, and a plurality of threaded holes are formed in the drive connection seat 66. When one of the side surfaces of the drive connection seat 66 is embedded in the second mounting groove 652, it is spirally connected to the corresponding matching threaded holes and threaded countersunk holes through bolts or studs to further improve the connection stability between the drive connection seat 66 and the second sealing connection seat 65.

[0079] Furthermore, in order to increase the material buffering capacity of the feed trough 1b, the notch of the feed trough 1b extends upward with an extended edge of a preset length to form a material guide channel housing connected to the feed trough 1b, and the material guide channel housing is a tubular structure. The material guide channel housing is provided with the blocking cover to cover the upper port of the material guide channel housing.
