[0021] like Figures 1 to 7 As shown, this utility model proposes a refrigeration storage device 100, including a cabinet 10, a door 11, and a beverage supply device 20. The cabinet 10 forms a cold storage cavity 101 with an opening inside. The door 11 is provided at the opening in an openable manner. The beverage supply device 20 includes a beverage storage section, a water outlet pipe 21, a flow control device 22, and a knob device 23. At least part of the beverage storage section is located inside the cold storage cavity 101. One end of the water outlet pipe 21 is connected to the beverage storage section, and the other end is located on the side of the door 11 away from the cold storage cavity 101. The flow control device 22 is provided on the water outlet pipe 21. The knob device 23 is connected to the side of the door 11 away from the cold storage cavity 101 and is electrically connected to the flow control device 22. The knob device 23 can control the flow control device 22 by rotating itself. The flow control device 22 is used to regulate the on / off state of the water outlet pipe 21 and / or the flow rate of the water outlet pipe 21.

[0022] As can be seen, the refrigeration and storage device 100 proposed in this utility model has a beverage supply device 20 with simple structure, low cost and convenient operation. The beverage storage section is used to store and refrigerate beverages. The water outlet pipe 21 can lead the beverages from the beverage storage section to the outside of the refrigeration and storage device 100 for convenient user access. The flow control device 22 controls whether the beverage flows out and / or the flow rate of the beverage. When the user needs to access the beverage, the water outlet pipe 21 can be connected by rotating the knob device 23, and the flow rate of the beverage can be adjusted by rotating the knob device 23. The knob device 23 can be implemented with a low-cost structure such as an encoder 25. Compared with the existing touch screen control, the beverage access cost is lower, blind operation is possible, and the operation feel is more comfortable.

[0023] For example, the refrigeration storage device 100 can be an electrical appliance such as a refrigerator that has refrigeration and preservation functions. A cold storage cavity 101 for refrigerating food is formed inside the cabinet 10. A refrigeration system creates a low-temperature environment inside the cabinet 10 to achieve the refrigeration function for food and beverages. The door 11 is rotatably connected to the cabinet via a hinge structure, enabling sealing and opening of the door 11 opening. A groove or protrusion can be provided on the outer side of the door 11, giving it a downward-facing end face. The water outlet can be located on this end face, allowing water to flow downwards, and a cup can be placed below the water outlet. The beverage storage section can be a box-shaped or trough-shaped container structure. Users can place beverages to be refrigerated into the beverage storage section for refrigeration. The beverage storage section can be installed on the side of the door 11 facing the cold storage cavity 101 and positioned high up to facilitate the flow of beverages by gravity. The beverage storage section can also be connected to an external water tank or water purification system, allowing external water to be pumped in for automatic beverage refrigeration. The beverage storage section can be entirely or partially placed within the cold storage chamber 101 to benefit from the low-temperature environment of the cold storage chamber 101. The beverage storage section can also be placed on the side of the door 11 in the width direction for convenient arrangement of shelves inside the door 11. One end of the water outlet pipe 21 is connected to the bottom of the beverage storage section. The water outlet pipe 21 can pass through the inside of the door 11 and exit from the groove or protrusion on the outside of the door 11. The flow control device 22 has an electrically controlled valve to control the flow rate of the water outlet pipe 21. The knob assembly is electrically connected to the flow control device 22 and adjusts the opening of the electrically controlled valve by rotation to control the liquid flow rate. The knob assembly can have multiple or infinitely many rotation angles, so that the opening of the electrically controlled valve is related to the rotation angle of the knob assembly. Alternatively, the knob assembly can have multiple rotation angles, so that the opening and opening time of the electrically controlled valve are simultaneously related to the rotation angle of the knob assembly. Specifically, the knob assembly can convert the rotation angle signal into an electrical signal through electrical components such as encoder 25, Hall sensor or potentiometer, and transmit it to the electric control valve for opening control. The overall structure is simple and the cost is low. The physical knob makes it convenient for users to operate blindly when taking water, which improves the user experience.

[0024] like Figures 3 to 7 As shown, in some embodiments of this utility model, the knob device 23 has a ring structure and is arranged around the end of the water outlet pipe 21 away from the beverage storage section.

[0025] As can be seen, by setting the knob device 23 into a ring structure, the knob device 23 has a hollow space, through which the water outlet pipe 21 is inserted, making the structure of the water outlet more compact. Furthermore, the near coaxial setting of the knob device 23 and the water outlet pipe 21 makes it convenient for the user to observe whether the liquid outlet speed of the water outlet pipe 21 meets the requirements when operating the knob device 23, so that the user can continue to rotate the knob device 23 to adjust the liquid outlet speed.

[0026] For example, the knob device 23 has two annular housings. One housing is arranged around the liquid outlet end of the water outlet pipe 21. A protruding part can be provided at the liquid outlet end, and the water outlet pipe 21 is inserted into the protruding part. An electrical component such as an encoder 25 or a Hall sensor that converts the rotation angle signal into an electrical signal is fixed on the outer side of the housing. Then, the other housing is rotatably connected to the fixed housing, so that the rotation angle can be collected by the knob device 23 and the electrical signal can be transmitted to the flow control device 22.

[0027] like Figure 1 , Figures 6 to 7 As shown, in some embodiments of this utility model, a water trough 111 is provided on the side of the door 11 away from the cold storage cavity 101. The water trough 111 is recessed towards the box body 10. A water outlet 243 is provided on the top side of the water trough 111 along the height direction of the box body 10. The end of the water outlet pipe 21 away from the beverage storage part passes through the water outlet 243. The knob device 23 is located in the water trough 111 and is arranged axially around the water outlet 243.

[0028] As can be seen, by setting a water dispensing trough 111 on the outside of the door body 11, and placing the knob device 23 and the liquid outlet end of the water outlet pipe 21 on the top side of the water dispensing trough 111, water can flow out from top to bottom, and the bottom of the water dispensing trough 111 can support the water cup, improving the user experience. The design of the water dispensing trough 111 also ensures that the knob device 23 and the water outlet pipe 21 do not protrude from the door body 11, making the overall structure simpler and more aesthetically pleasing.

[0029] For example, the water inlet 111 can be a rectangular trough with a rectangular opening. The horizontal cross-section of the water inlet 111 can be rectangular, trapezoidal, or semi-circular. The water inlet 111 can have a recessed structure integrally formed on the outer side of the door body 11, or it can be formed by multiple plates enclosing a trough structure that mates with the opening on the door body 11. The top side of the water inlet 111 can be independently installed by a plate-shaped bracket 24 for easy installation and maintenance. The bracket 24 can be snapped into the wall of the water inlet 111 integrally formed on the door body 11 using edge clips. The bracket 24 can have through holes for the water outlet pipe 21 to pass through. The knob device 23 can be fixedly connected to the bracket 24 by snapping, fasteners, or other means.

[0030] like Figure 1 , Figures 6 to 7 As shown, in some embodiments of this utility model, a connecting cylinder 241 is provided inside the water tank 111. One end of the connecting cylinder 241 is connected to the tank wall of the water tank 111 and communicates with the water outlet 243. The connecting cylinder 241 is located on the outer periphery of the water outlet 243. The end of the water outlet pipe 21 away from the beverage storage part is connected to the inner wall of the connecting cylinder 241. The knob device 23 is installed on the connecting cylinder 241.

[0031] As can be seen, by setting the connecting cylinder 241, the water outlet pipe 21 and the knob device 23 are installed on the connecting cylinder 241, making it less likely for the water to splash onto the wall of the water tank 111. In addition, the knob device 23 has sufficient operating space around it, making it convenient for users to operate and improving the user experience.

[0032] For example, the connecting cylinder 241 can be integrally formed with the bracket 24, that is, a portion of the connecting cylinder 241 extends out of the water outlet 243 of the bracket 24 to form a circular shape. The connecting cylinder 241 can also be independently installed on the bracket 24, coaxially arranged with the water outlet 243. The inner wall of the connecting cylinder 241 can be provided with a locking structure such as a slot to fix the water outlet pipe 21. The outer or inner peripheral wall of the connecting cylinder 241 can be provided with additional structures such as buckles or bolt holes to fix the knob device 23. Specifically, the knob device 23 can extend axially into the connecting cylinder 241 at one end and connect to the inner wall of the connecting cylinder 241, and extend axially out of the connecting cylinder 241 for convenient user operation. Alternatively, the knob device 23 can be sleeved on the outer peripheral wall of the connecting cylinder 241.

[0033] like Figures 3 to 7 As shown, in some embodiments of this utility model, the knob device 23 includes an encoder 25 and a knob housing 26. The encoder 25 is rotatably mounted on the connecting cylinder 241 and is arranged around the end of the water outlet pipe 21 away from the beverage storage section. The encoder 25 is electrically connected to the flow control device 22. The knob housing 26 covers the end of the encoder 25 along the axial direction of the connecting cylinder 241 away from the connecting cylinder 241.

[0034] As can be seen, the encoder 25 can be used to convert the rotation angle signal into an electrical signal. The encoder 25 has low cost and simple structure. When the user rotates the knob housing 26, the encoder 25 senses the rotation of the housing and converts the rotation angle signal into an electrical signal, which is then output to the flow control device 22 to control the flow rate of the beverage.

[0035] For example, the encoder 25 can be an existing optical encoder 25 or magnetic encoder 25, and its shape should be set as a ring structure to facilitate the connection of the water outlet pipe 21. The housing of the encoder 25 may include a fixed part 251 and a rotating part 252. The fixed part 251 can be connected to the inner or outer wall of the connecting cylinder 241 by snap-fit ​​or fasteners, and is coaxially arranged with the connecting cylinder 241. The electrical components of the encoder 25 are installed between the fixed part 251 and the rotating part 252. The knob housing 26 can be snap-fitted or fixedly connected to the rotating part 252 by fasteners, covering or sleeved on its outside to provide a rotating grip end for convenient user operation.

[0036] like Figure 3 , Figures 6 to 7As shown, in some embodiments of this utility model, along the axial direction of the connecting cylinder 241, the first end of the encoder 25 is located inside the connecting cylinder 241 and connected to the connecting cylinder 241, the second end of the encoder 25 is located outside the connecting cylinder 241, and the knob housing 26 is rotatably sleeved on the outer periphery of the second end.

[0037] As can be seen, by embedding one end of the encoder 25 into the connecting cylinder 241 along the axial direction and extending the other end out of the connecting cylinder 241 and rotating it with the knob housing 26, the encoder 25 is installed more reliably, and the knob housing 26 is located on the outside for easy user operation.

[0038] For example, the encoder 25 housing includes a fixed part 251 and a rotating part 252. The fixed part 251 has an annular structure and its outer side is connected to the inner wall of the connecting cylinder 241. The specific connection method can be a snap-fit, fastener, or interference fit. The electrical components of the encoder 25 can be installed on the outer side of the fixed part 251. The rotating part 252 can be rotatably connected to the fixed part 251 through a structure such as an annular slide rail or a rotating shaft. The electrical components of the encoder 25 are disposed between the fixed part 251 and the rotating part. For ease of operation, multiple limit positions can be set between the rotating part 252 and the fixed part 251 to realize multiple rotation positions of the knob device 23 to match the multiple flow levels of the flow control device 22.

[0039] like Figures 3 to 5 As shown, in some embodiments of this utility model, the inner wall of the connecting cylinder 241 is provided with a plurality of lugs 242, and the plurality of lugs 242 are arranged at intervals along the circumference of the connecting cylinder 241. The refrigeration storage device 100 also includes a plurality of fasteners, and the encoder 25 is connected to the plurality of lugs 242 respectively through the plurality of fasteners. And / or, the inner circumferential side of the knob housing 26 is provided with a plurality of first snap-fit ​​structures 261 arranged at intervals along the circumference of the connecting cylinder 241, and the outer circumferential side of the encoder 25 is provided with a plurality of second snap-fit ​​structures 253 arranged at intervals along the circumference of the connecting cylinder 241, and the first snap-fit ​​structures 261 and the second snap-fit ​​structures 253 are snap-fit ​​connected.

[0040] As can be seen, by providing multiple lugs 242 inside the connecting cylinder 241, and by providing bolt holes on the lugs 242, the outer periphery of the encoder 25 is connected to the lugs 242 using bolts or other fasteners, thereby achieving a stable installation of the encoder 25 on the connecting cylinder 241. Furthermore, by connecting the first snap-fit ​​structure 261 and the second snap-fit ​​structure 253, the knob housing 26 is snapped onto the encoder 25, making installation convenient and highly reliable.

[0041] For example, the encoder 25 has a cylindrical body and an annular boss at one axial end. A connecting post 254 is provided on the annular boss, and a bolt hole is provided in the connecting post 254. During installation, the encoder 25 is inserted into the connecting cylinder 241. At this time, the bolt hole of the connecting post 254 aligns with the bolt hole of the lug 242. Fasteners are passed through the annular boss and the lug 242 in sequence along the axial direction of the encoder 25 to achieve a tight connection between the annular boss and the lug 242. The first snap-fit ​​structure 261 can be a snap-fit ​​protrusion located inside the bowl-shaped knob housing 26. The snap-fit ​​protrusion extends along the axial direction of the encoder 25 and has a snap-fit ​​bevel at its end. The second snap-fit ​​structure 253 can be a snap-fit ​​groove located in the rotating part of the encoder 25. By pressing the knob housing 26 onto the encoder 25, the snap-fit ​​protrusion and the snap-fit ​​groove cooperate to achieve snap-fit.

[0042] like Figure 3 , Figures 6 to 7 As shown, in some embodiments of this utility model, the refrigeration storage device 100 further includes an ice-making device, which has an ice outlet channel 30 that is connected to the connecting cylinder 241.

[0043] As can be seen, by connecting the ice outlet channel 30 to the connecting cylinder 241, the connecting cylinder 241 integrates water outlet and ice outlet functions, making the overall structure more compact.

[0044] For example, the ice-making device can be an existing refrigerator ice-making device. After the ice cubes fall off, they can be discharged from the ice discharge channel 30. For this purpose, the diameter or cross-section of the connecting cylinder 241 can be designed to be large so that the ice cubes can flow out smoothly. The ice discharge channel 30 can be connected to the top side of the connecting cylinder 241 and is set at an angle to the connecting cylinder 241. To facilitate the control of ice dispensing, a pressure plate 31 device can be installed in the water tank 111. The ice dispensing function is activated by the pressure plate 31 device being squeezed by the water cup.

[0045] like Figure 3 As shown, in some embodiments of this utility model, the refrigeration storage device 100 further includes a control board 27, which is electrically connected to the knob device 23 and the flow control device 22 respectively. The control board 27 is located on the side of the door 11 away from the cold storage cavity 101. The control board 27 has a display section, which is used to display the flow rate or flow level of the flow control device 22.

[0046] As can be seen, the control board 27 receives electrical signals from the knob device 23 and outputs control signals to control the flow of the flow control device 22. The control board 27 is also equipped with a display to show the corresponding flow rate or flow level after the knob device 23 is rotated, so that the user can directly feel the flow rate.

[0047] For example, the control panel 27 can be mounted on the bracket 24 and installed vertically, so that the display on the control panel 27 can be parallel to the outer panel of the door 11. The display can be a display screen, and an outer cover 28 can be provided on the outside of the display screen. The outer cover 28 is fixed to the bracket 24 and is transparent to protect the display screen from damage by external forces. In addition, a knob device 23 can be provided to control only the water flow rate when rotated, and an additional switch can be provided on the knob device 23 to realize the opening and closing of the water flow function.

[0048] like Figures 2 to 3 As shown, in some embodiments of this utility model, the flow control device 22 further includes a flow meter and an electrically controlled valve. The electrically controlled valve is installed on the water outlet pipe 21, the flow meter is used to detect the flow rate of the water outlet pipe 21, and the control board 27 is electrically connected to the flow meter and the electrically controlled valve respectively.

[0049] As can be seen, the flow rate of the outlet pipe 21 is monitored by a flow meter, and the flow signal is transmitted to the control board 27. The control board 27 can display the flow rate or classify the flow rate into a preset flow range and display it in increments. The electrically controlled valve can receive control signals from the control board 27 to achieve automatic opening control. When the user rotates the knob device 23, the knob device 23 transmits the rotation angle signal as an electrical signal and transmits it to the control board 27. The control board 27 converts the preset flow rate corresponding to the electrical signal into a control signal to control the opening of the electrically controlled valve, thereby opening the water outlet and controlling the water flow rate.

[0050] For example, the flow meter can be a small, existing electrically controlled flow meter, and the electrically controlled valve can also be a small electrically controlled valve, both of which are electrically connected to the control board 27 to transmit signals. Alternatively, the flow meter can be mounted on the electrically controlled valve for fixed installation.

[0051] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
