refrigerator CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This disclosure claims priority to Chinese applications filed on April 25, 2024, with application numbers 202410506778.3, 202410506646.0 and 202410508449.2, the full text of which is incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of home appliance technology, and in particular to a refrigerator. Background Technology

[0003] As people's living standards continue to improve, refrigerators have become a necessity in people's lives. Refrigerators can cool purified water for drinking. However, more and more people now prefer to make their own beverages. Summary of the Invention

[0004] Specifically, this disclosure is achieved through the following technical solution.

[0005] According to a first aspect of the present disclosure, a refrigerator is provided, including a liquid supply assembly, a feed box, a mixing assembly, and a valve assembly. The mixing assembly has a mixing chamber and an inlet pipe, an outlet pipe, and a drain pipe respectively connected to the mixing chamber. The drain pipe is connected to the feed box, and the outlet pipe is connected to the refrigerator's liquid outlet. The valve assembly includes a third inlet and a third outlet. The third inlet is connected to the third outlet. The third inlet is connected to the liquid supply assembly. The third outlet is connected to the inlet pipe. When liquid flows from the inlet pipe to the outlet pipe, the drain pipe can generate a pressure difference with the outside environment, giving it self-priming capability to draw liquid from the feed box.

[0006] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects.

[0007] When a user makes a beverage using the refrigerator, the valve assembly controls the connection between the third inlet and the third outlet. Liquid from the supply assembly enters the inlet pipe of the mixing assembly through the valve assembly. When liquid enters the inlet pipe of the mixing assembly, it flows within the pipe, passes through the mixing chamber, and finally flows out through the outlet pipe. During this flow, due to the liquid's velocity, a pressure difference is created between the inlet pipe and the external environment according to the Venturi effect. This causes the inlet pipe to have a self-priming effect, drawing liquid from the container into the mixing chamber. There, it mixes evenly with the liquid from the supply assembly to create the beverage, which then flows out through the outlet pipe. Using a valve assembly allows for a faster response, connecting the third inlet and the third outlet. This ensures that liquid from the supply assembly flows to the mixing assembly, and the pressure difference in the pipeline also draws liquid from the container into the mixing chamber through the inlet pipe. This allows the user to receive a fully mixed beverage immediately after preparation, avoiding the situation where only liquid from the supply assembly is dispensed initially, thus improving the user experience.

[0088] References to any related technology in the specification are not, and should not be construed as, an admission or in any way an implication that such related technology constitutes part of the general knowledge of the application region or any other jurisdiction, or that such related technology could be reasonably understood and regarded as related by a person skilled in the art.

[0089] As people's living standards improve, refrigerators have become a necessity. Refrigerators use refrigeration to maintain a low temperature inside the storage compartment, thus better preserving food and preparing beverages with better taste. However, with a wide variety of refrigerator types and brands available, consumers have many choices. How to win consumer favor and enhance product competitiveness has become an increasingly important issue for refrigerator manufacturers.

[0090] Refrigerators can cool purified water for drinking. However, more and more users now prefer to make their own beverages. In related technologies, refrigerator-mounted beverage-making devices are complex in structure and the process is lengthy and time-consuming, often resulting in beverages that don't fully satisfy users.

[0091] In view of this, the present disclosure provides a refrigerator that makes beverages simple, fast, and produces beverages with uniform flavor, thereby improving the user experience.

[0092] As shown in Figures 1 and 2, this disclosure provides a refrigerator 1, including a cabinet assembly 10, a compressor 20, a condenser 30, an evaporator 40, and an expansion valve 50. The cabinet assembly 10 includes a cabinet component 11, a door component 12, a freezer compartment 13, and a refrigerator compartment 14. The freezer compartment 13 and the refrigerator compartment 14 are respectively disposed within the cabinet component 11. The door component 12 is rotatably connected to the cabinet component 11 to open or close the refrigerator compartment 14 and the freezer compartment 13. The compressor 20, condenser 30, evaporator 40, and expansion valve 50 are respectively disposed within the cabinet component 11, and at least a portion of the evaporator 40 is disposed within the freezer compartment 13.

[0093] As shown in Figure 3, when the refrigerator 1 is running, the compressor 20 outputs high-temperature, high-pressure gaseous refrigerant, which is then delivered to the condenser 30. The condenser 30 condenses the high-temperature, high-pressure gaseous refrigerant into medium-temperature, high-pressure refrigerant. This medium-temperature, high-pressure refrigerant then undergoes expansion and throttling through the expansion valve 50, further reducing its pressure and temperature. The resulting low-temperature, low-pressure liquid refrigerant flows out of the expansion valve 50 and into the evaporator 40. The low-temperature, low-pressure liquid refrigerant evaporates into gaseous refrigerant within the evaporator 40. At least a portion of the evaporator 40 is located within the freezer compartment 13, allowing the refrigerant to absorb a large amount of heat from the freezer compartment 13 during evaporation, thereby lowering the temperature within the freezer compartment 13 and facilitating the freezing of items, thus achieving the cooling function of the refrigerator 1. The refrigerant exiting the evaporator 40 is then returned to the compressor 20, forming a refrigerant circuit. In this way, the refrigerant continuously circulates within the refrigerant circuit to maintain the freezing environment of the freezer compartment 13 (e.g., below -1°C).

[0094] As shown in Figure 2, an air duct 15 is provided between the refrigerated compartment 14 and the frozen compartment 13 to facilitate the transfer of some of the cold air from the frozen compartment 13 to the refrigerated compartment 14, so as to reduce or maintain the low temperature environment (e.g., 2°C to 8°C) in the refrigerated compartment 14.

[0095] As shown in Figure 2, in some embodiments, along the height direction of the refrigerator 1, the freezer compartment 13 is located below the refrigerator compartment 14. The refrigerator 1 also includes a first fan (not labeled) disposed on the cabinet component 11. The air inlet or outlet of the first fan is connected to the air duct 15 and is used to transport part of the cold air from the freezer compartment 13 into the refrigerator compartment 14.

[0096] As shown in Figure 2, the height direction of refrigerator 1 is the Z-axis direction.

[0097] In some embodiments, the outer wall of the freezer compartment 13 is covered with an insulation layer (not shown) to separate the evaporator 40 from the compressor 20 and the condenser 30.

[0098] In some embodiments, the outer wall of the freezer compartment 13 is covered with an insulation layer (not shown).

[0099] In some embodiments, the refrigerator 1 further includes a heat dissipation assembly (not shown) disposed on the cabinet component 11, which is capable of dissipating heat from the condenser 30.

[0100] In some embodiments, the cabinet component 11 also includes a fresh-keeping compartment disposed on the cabinet component 11, which is located between the refrigerated compartment 14 and the frozen compartment 13 along the height direction of the refrigerator 1.

[0101] To meet users' needs for beverage preparation, as shown in Figures 1 and 4, in some embodiments, the refrigerator 1 further includes a beverage preparation device 100, which is installed on the door 101 of the door component 12. This beverage preparation device 100 has a simple structure, streamlines the beverage preparation process, and requires little preparation time. It can prepare beverages of different concentrations, and the ingredients and water are mixed more evenly, resulting in a more uniform flavor.

[0102] It should be noted that the beverage making device 100 can be installed in the refrigerator 1 in a modular manner, or multiple parts can be assembled into the refrigerator 1, in which case the multiple parts are assembled to form the beverage making device 100.

[0103] It should be noted that the beverage making device 100 can be installed anywhere inside the refrigerator, including the cabinet component 11 or the door component 12, etc.

[0104] In some embodiments, the beverage making device 100 is detachably connected to the door 101. The beverage making device 100 can be modularly installed in refrigerators 1 of various sizes, improving the adaptability of the beverage making device 100.

[0105] It should be noted that there are several ways to achieve the detachable connection of the beverage making device 100 to the door 101, including screw connection, snap connection, etc.

[0106] In some embodiments, the beverage making device 100 and the door 101 are detachably fixedly connected by a snap-fit ​​mechanism.

[0107] It should be noted that there are several ways to achieve the snap-fit ​​fixing between the beverage making device 100 and the door 101. For example, the cooperation between a buckle and a slot, or the cooperation between a protrusion and a hole, etc.

[0108] As shown in Figure 4, in some embodiments, one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot (not shown) that can engage with the buckle 102. The beverage making device 100 and the door 101 are connected by engaging the buckle 102 with the slot. This method facilitates installation and disassembly.

[0109] It should be noted that one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot that can engage with the buckle 102. This includes: the beverage making device 100 is provided with a buckle 102, and the door 101 is provided with a slot that can engage with the buckle 102; or the door 101 is provided with a buckle 102, and the beverage making device 100 is provided with a slot that can engage with the buckle 102.

[0110] As shown in Figures 2 to 9, in some embodiments, the refrigerator 1 includes a cabinet component 11 and a door component 12. The door component 12 is rotatably connected to the cabinet component 11 to open or close the cabinet component 11. The door component 12 includes a beverage preparation device 100, which includes a container 110, a liquid supply assembly 120, and a mixing assembly 130. The container 110 and the liquid supply assembly 120 are respectively connected to the mixing assembly 130 so that the liquid in the container 110 and the liquid in the liquid supply assembly 120 are mixed in the mixing assembly 130 to make a beverage.

[0111] As shown in Figures 6 to 13, in some embodiments, the mixing assembly 130 includes a mixing chamber 131 and an inlet pipe 132, an outlet pipe 133, and a drain pipe 134, all connected to the mixing chamber 131. The drain pipe 134 is connected to the feed box 110, and the outlet pipe 133 is connected to the outlet 1010 of the refrigerator 1. The beverage making apparatus 100 also includes a valve assembly 140, which includes a third inlet 141 and a third outlet 143. The third inlet 141 is connected to the third outlet 143. The third inlet 141 is connected to the liquid supply assembly 120. The third outlet 143 is connected to the inlet pipe 132. When liquid flows from the inlet pipe 132 to the outlet pipe 133, the drain pipe 134 can generate a pressure difference with the outside, giving the drain pipe 134 a self-priming capability, allowing it to draw liquid from the inlet of the drain pipe 134.

[0112] To better understand the content of this disclosure, this explanation uses the example of the liquid supply assembly 120 providing water and the feed container 110 providing a concentrated beverage solution. Of course, the liquid supply assembly 120 and the feed container 110 can also provide other liquids according to user needs. Further details will not be elaborated here.

[0113] Thus, when a user makes a beverage using refrigerator 1, valve assembly 140 controls the connection between the third inlet 141 and the third outlet 143, allowing water from the supply assembly 120 to enter the inlet pipe 132 of the mixing assembly 130 through valve assembly 140. When water flows into the inlet pipe 132 of the mixing assembly 130, it flows through the mixing chamber 131 and finally exits through the outlet pipe 133. During this flow, due to the water's velocity, a pressure difference is generated between the drainage pipe 134 and the outside environment according to the Venturi effect, causing the drainage pipe 134 to have a self-priming effect, drawing the concentrated liquid from the ingredient box 110 into the drainage pipe 134 and into the mixing chamber 131. There, it mixes evenly with the water from the supply assembly 120 to make the beverage, which then flows out through the outlet pipe 133. Using valve assembly 140 allows for a faster response in connecting the third inlet 141 and the third outlet 143. This allows water in the liquid supply component 120 to flow to the mixing component 130, and due to the pressure difference in the pipeline, the concentrate in the feed box 110 also enters the mixing chamber 131 through the drain pipe 134. This ensures that the user receives a fully mixed beverage immediately after preparation, avoiding the situation where only water from the liquid supply component 120 is dispensed when the beverage is first made, thus improving the user experience.

[0114] Furthermore, the use of the mixing component 130 enables automatic intake of concentrated liquid without the need for other power sources, saving costs and simplifying the overall structure of the beverage preparation device 100.

[0115] Researchers have discovered in practice that users not only demand flavored beverages but also flavorless ice water. Based on this, as shown in Figure 6, in some embodiments, the valve assembly 140 further includes a second outlet 142, and a third inlet 141 is connected to the second outlet 142. The second outlet 142 is connected to the liquid outlet 1010. Thus, when a user uses the beverage making device 100, if the user needs to make a flavored beverage, the valve assembly 140 is controlled to connect the third inlet 141 and the third outlet 143, allowing the water in the liquid supply assembly 120 and the concentrate in the ingredient box 110 to mix in the mixing chamber 131 to make the beverage. If the user needs flavorless ice water, the valve assembly 140 is controlled to connect the third inlet 141 and the second outlet 142, allowing the flavorless ice water from the liquid supply assembly 120 to flow directly out through the liquid outlet 1010 to provide ice water to the user.

[0116] It should be noted that the valve assembly 140 can be implemented in various ways, including a selector valve and a one-inlet, two-outlet solenoid valve, etc.

[0117] As shown in Figures 12 and 13, in some embodiments, the drainage pipe 134, the liquid inlet pipe 132, and the liquid outlet pipe 133 are respectively provided with a first inlet 1341, a second inlet 1322, and a first outlet 1333. The drainage pipe 134 is connected to the material box 110 through the first inlet 1341, the liquid inlet pipe 132 is connected to the liquid supply assembly 120 through the second inlet 1322, and the liquid outlet pipe 133 is connected to the liquid outlet 1010 through the first outlet 1333.

[0118] As shown in Figures 6 to 11, in some embodiments, the beverage making apparatus 100 further includes a three-way valve 107, with a first outlet 1333, a second outlet 142, and a liquid outlet 1010 respectively connected to the three-way valve 107. This allows the beverage flowing from the first outlet 1333 and the ice water flowing from the second outlet 142 to flow out through the three-way valve 107 from the liquid outlet 1010. Using the three-way valve 107 simplifies the water path of the beverage making apparatus 100, which is beneficial for miniaturizing the beverage making apparatus 100.

[0119] Researchers also discovered in practice that when liquid flows through the water path of the beverage preparation device 100, the liquid in the water flow may flow back into the ingredient container 110 or the liquid supply component 120, causing contamination of the concentrate in the ingredient container 110 or the water in the liquid supply component 120.

[0120] Based on this, as shown in Figures 6 to 11, in some embodiments, the beverage making device 100 further includes a first one-way valve 108, and the second outlet 142 is connected to the liquid outlet 1010 through the first one-way valve 108. Thus, when a user uses the beverage making device 100, the beverage can only flow from the second outlet 142 into the first one-way valve 108 and then to the liquid outlet 1010 in the water path, and cannot flow back to the liquid supply assembly 120 through the second outlet 142, thereby avoiding contamination of the water source.

[0121] As shown in Figures 6 to 11, in one embodiment, a first one-way valve 108 is connected between the second outlet 142 and the three-way valve 107. Thus, when a user uses the beverage making device 100 to make a beverage, the beverage flowing from the first outlet 1333 of the mixing component 130, upon passing through the three-way valve 107, will not flow to the second outlet 142 due to the action of the first one-way valve 108, preventing backflow to the liquid supply component 120 and contamination of the water source.

[0122] To ensure that the beverage concentration produced by the beverage making device 100 meets user needs, researchers experimentally verified the ratio of the flow rate of the inlet pipe 132 to the flow rate of the outlet pipe 134. In some embodiments, the ratio of the flow rate of the inlet pipe 132 to the flow rate of the outlet pipe 134 is X, where 1 ≤ X ≤ 2. Thus, by setting the ratio of the flow rate of the inlet pipe 132 to the flow rate of the outlet pipe 134 to 1 to 2, the user's desired beverage concentration can be met.

[0123] It should be noted that the testing process for setting the flow rate ratio of inlet pipe 132 to drainage pipe 134 to be 1-2 is as follows: Researchers introduce water into inlet pipe 132 and place water at the inlet of drainage pipe 134 for it to be drawn in. At this time, the flow rate ratio of water in inlet pipe 132 to drainage pipe 134 is 1-2. Of course, when the liquid introduced into inlet pipe 132 and drainage pipe 134 is not water, the flow rate ratio of inlet pipe 132 to drainage pipe 134 will change accordingly, which will not be elaborated here. Researchers found in experiments that when the flow rate ratio of water in inlet pipe 132 to drainage pipe 134 is designed to be 1-2, and when drainage pipe 134 is connected to material box 110 to draw in concentrate, the flow rate ratio of water in inlet pipe 132 to concentrate in drainage pipe 134 is 6-8. At this point, the ratio of water to concentrate is sufficient to meet the required mixing ratio, thus satisfying users' different concentration needs.

[0124] It should be noted that there are multiple ways to implement the hybrid component 130, including integral molding manufacturing, separate manufacturing and reassembly, etc.

[0125] As shown in Figures 12 and 13, in some embodiments, the inlet pipe 132 includes a first pipe section 1321 connected to the side wall of the mixing chamber 131, and the first pipe section 1321 communicates with the mixing chamber 131. The flow area of ​​the first pipe section 1321 gradually decreases along the direction from the inlet pipe 132 to the mixing chamber 131. Thus, designing the flow area of ​​the first pipe section 1321 to gradually decrease along the direction from the inlet pipe 132 to the mixing chamber 131 can increase the liquid flow rate. This improves the self-priming capability of the drainage pipe 134, allowing for better intake of liquid at the inlet of the drainage pipe 134. Furthermore, the mixing assembly 130 has a simple structure.

[0126] Researchers found that when the ratio of the water flow rate in the inlet pipe 132 to the water flow rate in the outlet pipe 134 was designed to be 1 to 2, it was achievable when the angle between the sidewall of the first pipe section 1321 and its central axis was 15° to 20°. Therefore, as shown in Figures 10 and 11, in some embodiments, the angle between the sidewall of the first pipe section 1321 and its central axis is A, where 15° ≤ A ≤ 20°.

[0127] It should be noted that there are many factors that affect the ratio of the water flow rate in the inlet pipe 132 to the water flow rate in the outlet pipe 134. The angle formed by the side wall of the first pipe section 1321 and the central axis of the first pipe section 1321 is only one of the influencing factors. Designing the angle range to be 15° to 20° can satisfy the ratio of 1 to 2 on the one hand, and on the other hand, the first pipe section 1321 within this angle range is easy to manufacture and helps to reduce costs.

[0128] Optionally, the angle A formed by the sidewall of the first pipe section 1321 and the central axis of the first pipe section 1321 can be 15°, 16°, 17°, 18°, 19°, 20°, etc.

[0129] Researchers also discovered in practice that the inner diameter of the drainage tube 134 affects the ratio of the water flow rate in the inlet tube 132 to the water flow rate in the drainage tube 134. Through experiments, they determined a range of inner diameters that favors a ratio of 1 to 2 between the water flow rate in the inlet tube 132 and the water flow rate in the drainage tube 134. In some embodiments, the inner diameter of the drainage tube 134 is D, where 3.5 mm ≤ D ≤ 4.5 mm. Thus, researchers experimentally verified that when the inner diameter D of the drainage tube 134 is 3.5 mm to 4.5 mm, the ratio of the water flow rate in the inlet tube 132 to the water flow rate in the drainage tube 134 can be maintained at 1 to 2.

[0130] Optionally, the inner diameter of the drainage tube 134 can be 3.5mm, 3.8mm, 4.0mm, 4.2mm, 4.5mm, etc.

[0131] As shown in Figures 12 and 13, in some embodiments, the outlet pipe 133 includes a second pipe section 1331 connected to the mixing chamber 131. The flow area of ​​the second pipe section 1331 gradually increases along the direction from the mixing chamber 131 to the outlet pipe 133. Thus, when water and concentrate are mixed in the mixing chamber 131 to make a beverage, the beverage flows out from the second pipe section 1331 of the outlet pipe 133. By utilizing the gradually increasing flow area of ​​the second pipe section 1331 along the direction from the mixing chamber 131 to the outlet pipe 133, turbulence within the outlet pipe 133 is reduced during the beverage's outflow, thereby improving dispensing efficiency and enhancing the user experience.

[0132] As shown in Figures 12 and 13, in some embodiments, the angle between the sidewall of the second pipe section 1331 and its central axis is B, where 6° ≤ B ≤ 9°. Researchers have experimentally verified that when the angle B between the sidewall of the second pipe section 1331 and its central axis is between 6° and 9°, the effect on reducing turbulence within the outlet pipe 133 is more significant.

[0133] Optionally, the angle B formed by the sidewall of the second pipe section 1331 and the central axis of the second pipe section 1331 can be 6°, 7°, 8°, 9°, etc.

[0134] It should be noted that the first pipe section 1321 and the second pipe section 1331 can be of various types, including tapered pipes, etc.

[0135] To improve the overall structural strength of the mixing component 130, as shown in FIG6, in some embodiments, the mixing component 130 further includes a plurality of connectors 135, which are disposed on the outer walls of the inlet pipe 132 and the outlet pipe 133, and the plurality of connectors 135 are arranged at intervals along the circumference of the inlet pipe 132 and the outlet pipe 133.

[0136] Furthermore, as the flow area of ​​the first pipe segment 1321 and the second pipe segment 1331 gradually decreases towards the mixing chamber 131, the diameters of the first pipe segment 1321 and the second pipe segment 1331 become smaller. Based on this, to further ensure the overall structural strength of the mixing assembly 130, as shown in Figures 10 and 11, in some embodiments, the mixing assembly 130 further includes multiple connectors 135. The connectors 135 are disposed on the outer walls of the first pipe segment 1321 and the second pipe segment 1331, and the multiple connectors 135 are spaced apart circumferentially along the first pipe segment 1321 and the second pipe segment 1331. Thus, the connectors 135 are connected to the outer walls of the first pipe segment 1321 and the second pipe segment 1331, and are spaced apart circumferentially, thereby strengthening the first pipe segment 1321 and the second pipe segment 1331. This ensures the overall structural strength of the mixing assembly 130.

[0137] As shown in Figures 12 and 13, in some embodiments, the outlet pipe 133 includes an outlet pipe section 1332, which is connected to the mixing chamber 131 via a second pipe section 1331. The flow area of ​​the outlet pipe section 1332 is larger than that of the inlet pipe 132, and the flow area of ​​the outlet pipe section 1332 is larger than that of the drainage pipe 134. Thus, since the liquids in the inlet pipe 132 and the drainage pipe 134 mix and flow out of the outlet pipe 133, if the flow area of ​​the outlet pipe section 1332 is less than or equal to the flow area of ​​the inlet pipe 132 and the flow area of ​​the drainage pipe 134, the resistance when the liquid flows to the outlet pipe will increase, thereby affecting the self-priming capacity of the drainage pipe 134 and causing a decrease in the flow rate of the concentrated liquid in the drainage pipe 134.

[0138] As shown in Figures 12 and 13, in some embodiments, the central axis of the inlet pipe 132 coincides with the central axis of the outlet pipe 133. The central axis of the drainage pipe 134 intersects with the central axis of the inlet pipe 132. By designing the central axes of the inlet pipe 132 and the outlet pipe 133 to coincide, the resistance to the liquid flow from the inlet pipe 132 to the outlet pipe 133 is reduced, preventing a decrease in the liquid flow rate and further improving the self-priming capability of the drainage pipe 134.

[0139] As shown in Figures 12 and 13, in some embodiments, the central axis of the drainage tube 134 is perpendicular to the central axis of the inlet tube 132. This perpendicular alignment of the central axis of the drainage tube 134 with the central axis of the inlet tube 132 further increases the self-priming capability of the drainage tube 134.

[0140] As shown in Figures 6 to 9, in some embodiments, the material box 110 is provided with a first receiving cavity 111 and a first interface 112 communicating with the first receiving cavity 111. The first receiving cavity 111 is used to hold the concentrate.

[0141] As shown in Figures 6, 7, and 10, in some embodiments, the liquid supply assembly 120 includes a water tank 121 and a water pump 122. The water tank 121 has a second receiving cavity 1211 and a second interface 1212 communicating with the second receiving cavity 1211. One end of the water pump 122 is connected to the second interface 1212, and the other end is connected to a second inlet 1322. Thus, when a user uses the beverage making device 100 to make a beverage, under the pumping action of the water pump 122, water from the water tank 121 enters the liquid inlet pipe 132 of the mixing assembly 130 and mixes with the concentrate in the mixing cavity 131 to make a beverage. Using the water tank 121 allows the water in the water tank 121 to be kept in a refrigerated environment, resulting in a better-tasting beverage. The water pump 122 increases the flow rate of water in the liquid inlet pipe 132, thereby improving the self-priming capability of the drainage pipe 134.

[0142] As shown in Figures 8, 9, and 11, in some embodiments, the liquid supply assembly 120 includes a valve 123 and a water tank 124. The valve 123 includes an inlet 1231 and an outlet 1232. One end of the water tank 124 is connected to the outlet 1232, and the other end is connected to a second inlet 1322. The inlet 1231 can be connected to an external water source. Thus, when a user uses the beverage making device 100 to make a beverage, the valve 123 opens, and external water enters the water tank 124 through the valve 123. The water in the water tank 124 enters the mixing chamber 131 through the liquid inlet pipe 132 and mixes with the concentrate in the mixing chamber 131 to make the beverage. The water in the water tank 124 is kept in a refrigerated environment, which also improves the taste of the beverage. By using an external water source, such as tap water, which has its own pressure, there is no need to install a separate water pump 122 to pump water. This allows the water entering the inlet pipe 132 to have a flow rate, thereby improving the self-priming capability of the drainage pipe 134.

[0143] Furthermore, since water tank 124 uses an external water source, there is no concern about water shortage compared to water box 121. Therefore, as shown in Figure 6, in some embodiments, given the limited overall space, the volume of the feed box 110 using an external water source is larger than the volume of the feed box 110 using water box 121. Thus, the beverage preparation device 100 using an external water source can reduce the frequency of adding concentrate, thereby improving the user experience.

[0144] Researchers have found in practice that in related technologies, the pipe assembly 160 is typically connected to the bottom wall of the container 110, allowing the concentrate in the container 110 to flow more effectively to the drain pipe 134 under gravity. However, this setup requires waiting until the concentrate in the container 110 is used up before disassembling the container 110; otherwise, the concentrate will overflow. Therefore, as shown in Figures 6 to 9, in some embodiments, the beverage preparation device 100 further includes a pipe assembly 160, with one end connected to the drain pipe 134 and the other end connected to the side wall of the container 110. A portion of the pipe assembly 160 is located inside the container 110, and along the direction of gravity, the inlet of the pipe assembly 160 abuts against the bottom wall of the container 110. Thus, by connecting the pipe assembly 160 to the side wall of the container 110, the container 110 can be easily disassembled without waiting for the concentrate to run out, improving the user experience. Furthermore, the pipe assembly 160 is abutted against the bottom wall of the material box 110, so that the concentrate in the material box 110 can be completely used up, avoiding waste.

[0145] As shown in Figures 6 to 9, in some embodiments, the material box 110 further includes a first cover 113, and the water box 121 includes a second cover 1213. A first interface 112 is disposed on the side wall of the material box 110 and close to the first cover 113, and a second interface 1212 is disposed on the side wall of the water box 121 and close to the second cover 1213. Thus, when the concentrate in the material box 110 and the water in the water box 121 are used up, the material box 110 and the water box 121 can be disassembled, and the first cover 113 and the second cover 1213 can be opened to add concentrate and water, respectively. By placing the first interface 112 and the second interface 1212 close to the cover, that is, by positioning the first interface 112 and the second interface 1212 at the top of the material box 110 and the water box 121, leakage of the material box 110 and the water box 121 when they are full of concentrate and water can be prevented.

[0146] As shown in Figures 14 and 15, in some embodiments, the beverage preparation apparatus 100 further includes a connecting pipe 170. The pipe assembly 160 is connected to the drain pipe 134 via the connecting pipe 170, and along the direction of gravity, the lowest point of the connecting pipe 170 is lower than the connection point between the connecting pipe 170 and the pipe assembly 160 and the drain pipe 134. Thus, connecting the connecting pipe 170 between the container 110 and the drain pipe 134, and ensuring that the lowest point of the connecting pipe 170 is lower than the connection point between the connecting pipe 170 and the pipe assembly 160 and the drain pipe 134 along the direction of gravity, allows the concentrated liquid to remain at the lowest point of the connecting pipe 170, thereby forming a liquid seal within the pipe and preventing the drain pipe 134 from drawing in air during self-priming, thus further improving the self-priming capability of the drain pipe 134.

[0147] It should be noted that there are many types of pipes that can be connected along the direction of gravity, including but not limited to U-shaped pipes, V-shaped pipes, etc.

[0148] As shown in Figures 14 and 15, in some embodiments, the beverage preparation apparatus 100 further includes a second one-way valve 109. The flow pipe assembly 160 is connected to the connecting pipe 170 via the second one-way valve 109. Thus, when a user uses the beverage preparation apparatus 100, the beverage can only flow from the container 110 through the second one-way valve 109 to the first inlet 1341 in the water path, and cannot flow back to the container 110 via the flow regulating assembly 150, thereby preventing contamination of the concentrate.

[0149] As shown in Figures 6 to 9, in some embodiments, the door assembly further includes a flow regulating component 150, which is disposed on the pipe assembly 160. Thus, the flow regulating component 150 can regulate the flow rate of the concentrate in the feed box 110, thereby further adjusting the ratio of the water flow rate in the inlet pipe 132 to the concentrate flow rate in the outlet pipe 134, to further meet the user's different concentration requirements. Researchers found in experiments that using the mixing component 130 can achieve a water flow rate ratio of 6 to 8 in the inlet pipe 132 to the concentrate flow rate in the outlet pipe 134. Further adjusting the concentrate flow rate using the flow regulating component 150 can change this ratio to 6 to 12, thereby further meeting the user's different concentration requirements.

[0150] It should be noted that the flow regulation component 150 can be implemented in various ways, including regulating valve, throttle valve, manual regulating component 151, etc.

[0151] As shown in Figures 14 to 18, in some embodiments, the pipe assembly 160 includes a flexible section, and the flow regulating assembly 150 includes an adjusting member 151 and a supporting member 152. The supporting member 152 includes an abutment body 1521 and a mating body 1522 connected to the abutment body 1521. The adjusting member 151 and the mating body 1522 are movably connected, and the adjusting member 151 and the mating body 1522 can be fixedly connected. The abutment body 1521 and the adjusting member 151 are located on both sides of the pipe assembly 160, and the adjusting member 151 can move to press against the flexible section to adjust the flow area of ​​the pipe assembly 160. Thus, when the concentration of the beverage needs to be adjusted, the adjusting member 151 moves and presses against the flexible part of the pipe assembly 160, while the abutting body 1521 presses against the other side of the pipe assembly 160, thereby adjusting the inner diameter of the pipe assembly 160. This flow regulating component 150 has a simple structure and a simple adjustment method, allowing the refrigerator 1 to adjust the flow rate according to user needs, and the flow rate adjustment method is simple. It can also be used to change the flow rate of the concentrate, thereby changing the concentration of the beverage. When the adjusting member 151 moves to the target position, it can be fixedly connected to the mating part, thereby fixing the flow rate and thus fixing the concentration of the beverage. This flow regulating component 150 has a simple structure and a simple adjustment method, allowing the beverage making device 100 to make beverages of different concentrations according to user needs, and the making method is simple.

[0152] It should be noted that the flexible part of the pipe assembly 160 can deform under stress, thereby changing the flow area of ​​the pipe assembly 160.

[0153] In some embodiments, the conduit assembly 160 includes a flexible conduit, an abutment 1521 and an adjusting member 151 located on opposite sides of the flexible conduit, with at least a portion of the abutment 1521 abutting against a sidewall of the flexible conduit. The adjusting member 151 is movable to press against a sidewall of the flexible conduit.

[0154] It should be noted that flexible pipes can be made of various materials, including but not limited to PVC hoses, silicone hoses, rubber hoses, etc.

[0155] As shown in Figures 16 to 18, in some embodiments, the carrier 152 further includes a connector 1523, through which the mating body 1522 is fixedly connected to the abutment body 1521. Thus, by fixing the mating body 1522 and the abutment body 1521 together via the connector 1523, the overall strength of the carrier 152 is improved.

[0156] As shown in Figures 16 to 18, in some embodiments, the abutment 1521, the connector 1523, and the mating body 1522 are integrally formed. This reduces assembly steps and further improves the overall strength of the load-bearing member 152.

[0157] In some embodiments, the adjusting member 151 and the mating body 1522 are slidably connected, and when the adjusting member 151 moves to the target position, the adjusting member 151 can be engaged and fixed with the mating body 1522.

[0158] Of course, the flow regulating component 150 can also be implemented in other ways, as shown in Figures 16 to 18. In another embodiment, the regulating component 151 includes a screw 1511 and a first abutment portion 1512 fixedly connected to the screw 1511. The mating body 1522 is provided with an internally threaded hole 103 that is screwed into the screw 1511. The screw 1511 is driven to engage with the internally threaded hole 103, causing the first abutment portion 1512 to move and press against the side wall of the pipe assembly 160, thereby adjusting the inner diameter of the pipe assembly 160. Thus, when the user needs to adjust the concentration of the beverage, by rotating the screw 1511, which is driven to engage with the internally threaded hole 103 of the mating body 1522, the screw 1511 moves along its axis, thereby causing the first abutment portion 1512 to move and cooperate with the abutment body 1521 to squeeze the pipe assembly 160, thereby controlling the inner diameter of the pipe assembly 160 to change the flow rate of the concentrate, and thus change the concentration of the beverage. When the target concentration is reached, the self-locking screw 1511 stops rotating, thus fixing the flow rate of the concentrate and maintaining a consistent beverage concentration. Furthermore, this adjustment method allows for continuous and smooth concentration adjustment, rather than switching between specific discrete levels, achieving stepless flow rate regulation and improving the user experience.

[0159] As shown in Figure 18, in some embodiments, the first abutment portion 1512 is arc-shaped. Thus, when the user needs to adjust the concentration of the beverage, the arc-shaped first abutment portion 1512, when pressing against the pipe assembly 160, can disperse the squeezing force on the pipe assembly 160, preventing damage to the pipe assembly 160, thereby improving the reliability of the beverage preparation device 100 and the refrigerator 1.

[0160] As shown in Figures 8 and 9, in some embodiments, the abutment body 1521 includes a second abutment portion 104. The second abutment portion 104 is provided with an abutment groove 105 adapted to the pipe assembly 160. The pipe assembly 160 can be installed in the abutment groove 105, and the inner wall of the abutment groove 105 abuts against the side wall of the pipe assembly 160. In this way, the abutment groove 105 can limit the pipe assembly 160, and when the user needs to adjust the concentration of the beverage, the abutment groove 105 adapted to the pipe assembly 160 can disperse the squeezing force received by the pipe assembly 160, avoiding damage to the pipe assembly 160, thereby improving the reliability of the beverage making device 100 and the refrigerator 1.

[0161] Researchers found in practice that the optimal user experience occurs when the number of rotations of screw 1511 is less than or equal to one full turn when adjusting the beverage concentration. In some embodiments, three-quarters of the screw pitch is greater than or equal to the radius of the inner diameter of the pipe assembly 160. Thus, when a user needs to adjust the beverage concentration, they only need to rotate screw 1511 less than or equal to three-quarters of a turn to achieve the desired concentration, improving the user experience.

[0162] Of course, in other embodiments, the pitch of the screw 1511 may be greater than or equal to the radius of the inner diameter of the pipe assembly 160. Alternatively, half of the pitch of the screw 1511 may be greater than or equal to the radius of the inner diameter of the pipe assembly 160. Or, one-quarter of the pitch of the screw 1511 may be greater than or equal to the radius of the inner diameter of the pipe assembly 160.

[0163] To facilitate user rotation of the screw 1511, as shown in Figure 18, in some embodiments, the carrier 152 further includes a rotating body 1524, which is fixedly connected to the screw 1511. Thus, when the user needs to adjust the concentration of the beverage, by utilizing the fixed connection between the rotating body 1524 and the screw 1511, the user only needs to rotate the rotating body 1524 to rotate the screw 1511, thereby controlling the inner diameter of the pipe assembly 160 to change the flow rate of the concentrate and thus the concentration of the beverage. This further improves the user experience.

[0164] Further, as shown in Figures 19 and 20, in some embodiments, the beverage preparation apparatus 100 further includes a housing assembly 180. The housing assembly 180 has a cavity 181 and a mounting groove 182 communicating with the cavity 181. The flow regulating assembly 150 is located inside the cavity 181. A rotating body 1524 is mounted in the mounting groove 182, and at least a portion of the rotating body 1524 is located outside the housing assembly 180. In this way, the housing assembly 180 can protect the flow regulating assembly 150. By mounting the rotating body 1524 in the mounting groove 182, and with at least a portion of the rotating body 1524 located outside the housing assembly 180, the user can control the flow regulating assembly 150 to adjust the concentration of the beverage from outside the housing assembly 180.

[0165] As shown in Figures 19 and 20, in some embodiments, the outer wall of the housing assembly 180 is provided with a scale for beverage concentration, and the scale is circumferentially located in the mounting groove 182. The rotating body 1524 includes a pointing part 106, which points to the scale corresponding to the beverage concentration produced by the beverage making device 100. Thus, by providing a scale corresponding to the beverage concentration on the outer wall of the housing assembly 180, when the user needs to adjust the beverage concentration, they only need to rotate the rotating body 1524 to point the pointing part 106 to the target concentration to produce a beverage of the corresponding concentration, improving the user experience.

[0166] To facilitate user judgment of the amount of concentrate and water in the ingredient container 110 and water container 121 of the beverage preparation apparatus 100, as shown in Figures 17 and 18, in some embodiments, the sidewall of the ingredient container 110 is transparent. The beverage preparation apparatus 100 also includes a housing assembly 180, which has a cavity 181 in which the ingredient container 110 is located. Along the width direction of the ingredient container 110, at least a portion of the sidewall of the housing assembly 180 corresponding to the ingredient container 110 is transparent. Thus, the user can observe the amount of concentrate in the ingredient container 110 through the transparent sidewall of the housing assembly 180, making it easier for the user to better judge when to add concentrate, avoiding liquid shortage during beverage preparation, and improving the user experience.

[0167] As shown in Figures 19 and 20, in some embodiments, the sidewall of the water tank 121 is transparent. The beverage making apparatus 100 also includes a housing assembly 180, which has a cavity 181 in which the water tank 121 is located. Along the width direction of the water tank 121, at least a portion of the sidewall of the housing assembly 180 corresponding to the water tank 121 is transparent. Thus, the user can observe the water level in the water tank 121 through the transparent sidewall of the housing assembly 180, making it easier for the user to better judge when to add water, avoiding water shortage during beverage making, and improving the user experience.

[0168] It should be noted that the width direction of the material box 110 and the water box 121 is the X direction as shown in Figure 6 and Figure 8.

[0169] Of course, referring back to Figures 4, 7, and 9, in some embodiments, the beverage making apparatus 100 further includes a liquid level detection component 190. The liquid level detection component 190 is respectively disposed on the side walls of the water tank 121 and the ingredient tank 110, and the height of the liquid level detection component 190 along the direction of gravity is greater than the height of the bottom wall of the water tank 121 and the ingredient tank 110 along the direction of gravity, in order to detect the liquid level of the water tank 121 and the ingredient tank 110. Thus, the user can know through the liquid level detection component 190 whether the liquid level of the water tank 121 and the ingredient tank 110 is too low, thereby promptly reminding the user to add concentrate or water, preventing the beverage making apparatus 100 from running out of liquid during beverage making, thereby improving the user experience.

[0170] It should be noted that the liquid level detection component 190 can be implemented in various ways, including using a capacitive sensor, etc.

[0171] It should be noted that the above embodiments can complement each other without conflict.

[0172] The components included in the “components,” “devices,” and “equipment” disclosed herein can be flexibly combined. They can be modularly produced according to actual needs and assembled as an independent module; or they can be assembled separately to form a module in this device.

[0178] In related technologies, the beverage making device equipped with a refrigerator has a complex structure, and the process of mixing water and concentrate to make a beverage is complicated, making it difficult to meet the needs of different users in terms of the concentration range of the beverage.

[0179] In view of this, the present disclosure provides a mixing component, a door component, and a refrigerator. The mixing component has a simple structure, the process of mixing liquids to make beverages using the mixing component is simple, and the concentration range of the beverages produced can meet the needs of users.

[0180] As shown in Figure 21, in some embodiments, one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot (not shown) that can engage with the buckle 102. The beverage making device 100 and the door 101 are connected by engaging the buckle 102 with the slot. This method facilitates installation and disassembly.

[0181] It should be noted that one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot that can engage with the buckle 102. This includes: the beverage making device 100 is provided with the buckle 102, and the door 101 is provided with a slot that can engage with the buckle 102. Alternatively, the door 101 is provided with the buckle 102, and the beverage making device 100 is provided with a slot that can engage with the buckle 102.

[0182] As shown in Figures 21 to 27, in some embodiments, the refrigerator 1 includes a cabinet component 11 and a door component 12. The door component 12 is rotatably connected to the cabinet component 11 to open or close the cabinet component 11. The door component 12 includes a beverage preparation device 100, which includes a container 110, a liquid supply assembly 120, and a mixing assembly 130. The container 110 and the liquid supply assembly 120 are respectively connected to the mixing assembly 130 so that the liquid in the container 110 and the liquid in the liquid supply assembly 120 are mixed in the mixing assembly 130 to make a beverage.

[0183] To better understand the hybrid component 130 of this disclosure, the scenario in which the hybrid component 130 is applied to the door component 12 and the refrigerator 1 will be described.

[0184] As shown in Figures 21 to 27, in some embodiments, the mixing assembly 130 includes a mixing chamber 131 and an inlet pipe 132, an outlet pipe 133, and a drain pipe 134, all of which are respectively connected to the mixing chamber 131. The inlet pipe 132 includes a first pipe section 1321 connected to the side wall of the mixing chamber 131 and communicating with the mixing chamber 131. The flow area of ​​the first pipe section 1321 gradually decreases along the direction from the inlet pipe 132 to the mixing chamber 131. When liquid flows from the inlet pipe 132 to the outlet pipe 133, the drain pipe 134 can generate a pressure difference with the outside, so that the drain pipe 134 has a self-priming capability and can draw liquid from the inlet of the drain pipe 134. The ratio of the flow rate of the inlet pipe 132 to the flow rate of the drain pipe 134 is X, where 1 ≤ X ≤ 2. The liquid supply assembly 120 is connected to the inlet pipe 132, and the material box 110 is connected to the drain pipe 134.

[0185] To better understand the content of this disclosure, this explanation uses the example of the liquid supply assembly 120 providing water and the feed container 110 providing a concentrated beverage solution. Of course, the liquid supply assembly 120 and the feed container 110 can also provide other liquids according to user needs. Further details will not be elaborated here.

[0186] Thus, when water from the liquid supply component 120 is introduced into the inlet pipe 132 of the mixing component 130, due to the flow velocity of the water, a pressure difference will be generated between the inside of the drainage pipe 134 and the outside environment according to the Venturi effect, thereby giving the drainage pipe 134 a self-priming effect. Since the drainage pipe 134 is connected to the material box 110, it can draw the concentrated liquid from the material box 110 into the drainage pipe 134, which then enters the mixing chamber 131 to mix with water to form a beverage, which finally flows out through the outlet pipe 133. Designing the flow area of ​​the first pipe section 1321 to gradually decrease along the direction from the inlet pipe 132 to the mixing chamber 131 increases the liquid flow velocity, thereby improving the self-priming ability of the drainage pipe 134 and better drawing in the liquid at the inlet of the drainage pipe 134. Furthermore, the mixing component 130 has a simple structure.

[0187] The testing process for setting the flow rate ratio of inlet pipe 132 to drainage pipe 134 to be 1-2 is as follows: Researchers introduce water into inlet pipe 132 and place water at the inlet of drainage pipe 134 for it to be drawn in. At this time, the flow rate ratio of water in inlet pipe 132 to drainage pipe 134 is 1-2. Of course, when the liquid introduced into inlet pipe 132 and drainage pipe 134 is not water, the flow rate ratio of inlet pipe 132 to drainage pipe 134 will change accordingly, which will not be elaborated here. Researchers found in the experiment that when the flow rate ratio of water in inlet pipe 132 to water in drainage pipe 134 is designed to be 1-2, and when drainage pipe 134 is connected to material box 110 to draw in concentrate, the flow rate ratio of water in inlet pipe 132 to concentrate in drainage pipe 134 is 6-8. At this point, the ratio of water to concentrate is sufficient to meet the required mixing ratio, thus satisfying users' different concentration needs.

[0188] It should be noted that there are multiple ways to implement the hybrid component 130, including integral molding manufacturing, separate manufacturing and reassembly, etc.

[0189] As shown in Figures 21 to 27, in some embodiments, the liquid supply assembly 120 includes a water tank 121 and a water pump 122. The water tank 121 is connected to the inlet pipe 132 via the water pump 122. Thus, when a user uses the beverage making device 100 to make a beverage, the water in the water tank 121 enters the inlet pipe 132 of the mixing assembly 130 under the pumping action of the water pump 122, and mixes with the concentrate in the mixing chamber 131 to make a beverage. Using the water tank 121 allows the water in the water tank 121 to be kept in a refrigerated environment, resulting in a better taste for the beverage. Under the action of the water pump 122, the flow rate of the water in the inlet pipe 132 can be increased, thereby improving the self-priming capability of the drainage pipe 134.

[0190] As shown in Figures 21 to 27, in some embodiments, the liquid supply assembly 120 includes a valve 123 and a water tank 124. One end of the valve 123 is connected to an external water source, and the other end is connected to the water tank 124, which is connected to the inlet pipe 132. Thus, when a user uses the beverage making device 100 to make a beverage, the valve 123 opens, and the external water source enters the water tank 124 through the valve 123. The water in the water tank 124 enters the mixing chamber 131 through the inlet pipe 132 and mixes with the concentrate in the mixing chamber 131 to make the beverage. The water in the water tank 124 is kept in a refrigerated environment, which also improves the taste of the beverage. Using an external water source, such as tap water, which has its own pressure, eliminates the need for a separate water pump 122 to draw water, allowing the water entering the inlet pipe 132 to have a flow rate, thereby improving the self-priming capacity of the drainage pipe 134.

[0191] As shown in Figures 21 to 27, in some embodiments, the door assembly further includes a flow regulating component 150, and the feed box 110 is connected to the drain pipe 134 via the flow regulating component 150. Thus, the flow regulating component 150 can regulate the flow rate of the concentrate in the feed box 110, thereby further adjusting the ratio of the water flow rate in the inlet pipe 132 to the concentrate flow rate in the drain pipe 134, to further meet the user's different concentration requirements. Researchers found in experiments that using this mixing component 130 can achieve a water flow rate ratio of 6 to 8 in the inlet pipe 132 to the concentrate flow rate in the drain pipe 134. Further adjusting the concentrate flow rate using the flow regulating component 150 can change this ratio to 6 to 12, thereby further meeting the user's different concentration requirements.

[0192] As shown in Figures 21 to 27, in some embodiments, the door component 12 further includes a connecting pipe 170, which includes an inlet 2151 and an outlet 2152. The material box 110 is connected to the inlet 2151, and the drain pipe 134 is connected to the outlet 2152. Along the direction of gravity, the lowest point of the connecting pipe 170 is lower than both the inlet 2151 and the outlet 2152. Thus, the connecting pipe 170 connects the material box 110 and the drain pipe 134, and the lowest point of the connecting pipe 170 is lower than both the inlet 2151 and the outlet 2152. This allows the concentrate to remain at the lowest point of the connecting pipe 170, forming a liquid seal and preventing the drain pipe 134 from drawing in air during self-priming, thereby further improving the self-priming capability of the drain pipe 134.

[0193] It should be noted that there are many types of connecting pipes 170 that can achieve the lowest point of the connecting pipe 170 being lower than the liquid inlet 2151 and the liquid outlet 2152 along the direction of gravity, including but not limited to U-shaped pipes, V-shaped pipes, etc.

[0194] Researchers found that when the ratio of the water flow rate in the inlet pipe 132 to the water flow rate in the outlet pipe 134 was designed to be 1 to 2, it was achievable when the angle between the sidewall of the first pipe section 1321 and its central axis was 15° to 20°. Therefore, as shown in Figures 21 to 27, in some embodiments, the angle between the sidewall of the first pipe section 1321 and its central axis is A, where 15° ≤ A ≤ 20°.

[0195] It should be noted that there are many factors that affect the ratio of the water flow rate in the inlet pipe 132 to the water flow rate in the outlet pipe 134. The angle formed by the side wall of the first pipe section 1321 and the central axis of the first pipe section 1321 is only one of the influencing factors. Designing the angle range to be 15° to 20° can satisfy the ratio of 1 to 2 on the one hand, and on the other hand, the first pipe section 1321 within this angle range is easy to manufacture and helps to reduce costs.

[0196] Optionally, the angle A formed by the sidewall of the first pipe section 1321 and the central axis of the first pipe section 1321 can be 15°, 16°, 17°, 18°, 19°, 20°, etc.

[0197] Researchers also discovered in practice that the inner diameter of the drainage tube 134 affects the ratio of the water flow rate in the inlet tube 132 to the water flow rate in the drainage tube 134. Through experiments, they determined a range of inner diameters that favors a ratio of 1 to 2 between the water flow rate in the inlet tube 132 and the water flow rate in the drainage tube 134. In some embodiments, the inner diameter of the drainage tube 134 is D, where 3.5 mm ≤ D ≤ 4.5 mm. Thus, researchers experimentally verified that when the inner diameter D of the drainage tube 134 is 3.5 mm to 4.5 mm, the ratio of the water flow rate in the inlet tube 132 to the water flow rate in the drainage tube 134 can be maintained at 1 to 2.

[0198] Optionally, the inner diameter of the drainage tube 134 can be 3.5mm, 3.8mm, 4.0mm, 4.2mm, 4.5mm, etc.

[0199] As shown in Figures 21 to 27, in some embodiments, the dispensing pipe 133 includes a second pipe section 1331 connected to the mixing chamber 131. The flow area of ​​the second pipe section 1331 gradually increases along the direction from the mixing chamber 131 to the dispensing pipe 133. Thus, when water and concentrate are mixed in the mixing chamber 131 to make a beverage, the beverage flows out through the second pipe section 1331 of the dispensing pipe 133. By utilizing the gradually increasing flow area of ​​the second pipe section 1331 along the direction from the mixing chamber 131 to the dispensing pipe 133, turbulence within the dispensing pipe 133 is reduced during the beverage's flow, thereby improving dispensing efficiency and enhancing the user experience.

[0200] As shown in Figures 21 to 27, in some embodiments, the angle between the sidewall of the second pipe section 1331 and its central axis is B, where 6° ≤ B ≤ 9°. Researchers have experimentally verified that when the angle B between the sidewall of the second pipe section 1331 and its central axis is between 6° and 9°, the effect on reducing turbulence within the outlet pipe 133 is more significant.

[0201] Optionally, the angle B formed by the sidewall of the second pipe section 1331 and the central axis of the second pipe section 1331 can be 6°, 7°, 8°, 9°, etc.

[0202] It should be noted that the first pipe section 1321 and the second pipe section 1331 can be of various types, including tapered pipes, etc.

[0203] As the flow area of ​​the first pipe section 1321 and the second pipe section 1331 gradually decreases towards the mixing chamber 131, the diameters of the first pipe section 1321 and the second pipe section 1331 become smaller. Therefore, to ensure the overall structural strength of the mixing assembly 130, as shown in Figures 21 to 27, in some embodiments, the mixing assembly 130 further includes multiple connectors 135. The connectors 135 are disposed on the outer walls of the first pipe section 1321 and the second pipe section 1331, and the multiple connectors 135 are spaced apart circumferentially along the first pipe section 1321 and the second pipe section 1331. Thus, the connectors 135 are connected to the outer walls of the first pipe section 1321 and the second pipe section 1331, and are spaced apart circumferentially, thereby strengthening the first pipe section 1321 and the second pipe section 1331. This ensures the overall structural strength of the mixing assembly 130.

[0204] As shown in Figures 21 to 27, in some embodiments, the outlet pipe 133 includes an outlet pipe section 1332, which is connected to the receiving cavity via a first pipe section 1321. The flow area of ​​the outlet pipe section 1332 is larger than that of the inlet pipe 132, and the flow area of ​​the outlet pipe section 1332 is larger than that of the drainage pipe 134. Thus, since the liquids in the inlet pipe 132 and the drainage pipe 134 mix and flow out of the outlet pipe 133, if the flow area of ​​the outlet pipe section 1332 is less than or equal to the flow area of ​​the inlet pipe 132 and the flow area of ​​the drainage pipe 134, the resistance when the liquid flows to the outlet pipe will increase, thereby affecting the self-priming capacity of the drainage pipe 134 and causing a decrease in the flow rate of the concentrated liquid in the drainage pipe 134.

[0205] As shown in Figures 21 to 27, in some embodiments, the central axis of the inlet pipe 132 coincides with the central axis of the outlet pipe 133. The central axis of the drainage pipe 134 intersects with the central axis of the inlet pipe 132. By designing the central axes of the inlet pipe 132 and the outlet pipe 133 to coincide, the resistance to the liquid flow from the inlet pipe 132 to the outlet pipe 133 is reduced, preventing a decrease in the liquid flow rate and further improving the self-priming capability of the drainage pipe 134.

[0206] As shown in Figures 21 to 27, in some embodiments, the central axis of the drainage tube 134 is perpendicular to the central axis of the inlet tube 132. This perpendicular alignment of the central axis of the drainage tube 134 with the central axis of the inlet tube 132 further increases the self-priming capability of the drainage tube 134.

[0207] In related technologies, most refrigerators cannot make flavored beverages, or the beverage making process is complicated, the beverage ratio is inaccurate, and the beverage concentration and taste are difficult to meet the user's needs.

[0208] In view of this, the present disclosure provides a cabinet door component and a refrigerator. This cabinet door component simplifies the process of making beverages and allows for more even mixing of ingredients and water, resulting in a more uniform flavor in the beverage.

[0209] As shown in Figure 28, in some embodiments, one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot (not shown) that can engage with the buckle 102. The beverage making device 100 and the door 101 are connected by engaging the buckle 102 with the slot. This method facilitates installation and disassembly.

[0210] It should be noted that one of the beverage making device 100 and the door 101 is provided with a buckle 102, and the other is provided with a slot that can engage with the buckle 102. This includes: the beverage making device 100 is provided with the buckle 102, and the door 101 is provided with a slot that can engage with the buckle 102. Alternatively, the door 101 is provided with the buckle 102, and the beverage making device 100 is provided with a slot that can engage with the buckle 102.

[0211] As shown in Figures 28 to 34, in some embodiments, the beverage preparation apparatus 100 includes a container 110, a liquid supply assembly 120, a dispenser 3130, and a mixing assembly 130. The container 110 has a first receiving cavity 111 and a first interface 112 communicating with the first receiving cavity 111, the first receiving cavity 111 being used to hold concentrated liquid. The dispenser 3130 includes a liquid outlet 1010, through which the dispenser 3130 can supply beverages to the outside. The mixing assembly 130 has a mixing cavity 131 and a first inlet 1341, a second inlet 1322, and a first outlet 1333 respectively communicating with the mixing cavity 131. The container 110 is connected to the first inlet 1341 via the first interface 112, the second inlet 1322 is connected to the liquid supply assembly 120, and the first outlet 1333 is connected to the liquid outlet 1010.

[0212] Thus, when a user uses the beverage making device 100 to make a beverage, the concentrated liquid in the first receiving chamber 111 of the ingredient container 110 and the water in the liquid supply component 120 enter the mixing chamber 131 of the mixing component 130 through the first inlet 1341 and the second inlet 1322, respectively, to mix the concentrated liquid and the water. This process allows the concentrated liquid and water in the ingredient container to be mixed more evenly, resulting in a more uniform flavor in the beverage. Finally, the prepared beverage is provided to the outside through the liquid outlet 1010 of the dispenser 3130. In addition, the refrigeration environment of the refrigerator 1 can also improve the taste of the beverage.

[0213] It should be noted that the liquid supplied by the liquid supply assembly 120 includes water. In this disclosure, water supply by the liquid supply assembly 120 is used as an example for illustration. Of course, the liquid supply assembly 120 can also supply other liquids according to user needs. Further details will not be elaborated here.

[0214] As shown in Figures 28 to 34, in some embodiments, the beverage making apparatus 100 further includes a flow regulating component 150, and the ingredient box 110 is connected to the first inlet 1341 via the flow regulating component 150. Thus, the flow rate of the concentrate can be controlled via the flow regulating component 150, thereby producing beverages of different concentrations.

[0215] It should be noted that the flow regulation component 150 can be implemented in various ways, including regulating valves, throttle valves, manual regulating components, etc.

[0216] As shown in Figures 30 and 31, in one embodiment, the liquid supply assembly 120 includes a water tank 121 and a water pump 122. The water tank 121 has a second receiving cavity 1211 and a second interface 1212 communicating with the second receiving cavity 1211. One end of the water pump 122 is connected to the second interface 1212, and the other end is connected to a second inlet 1322. Thus, when a user uses the beverage making device 100 to make a beverage, under the pumping action of the water pump 122, water from the water tank 121 enters the second inlet 1322 of the mixing assembly 130 through the second interface 1212, and mixes with the concentrate in the mixing cavity 131 to make a beverage. Using the water tank 121 allows the water in the water tank 121 to be kept in a refrigerated environment, resulting in a better-tasting beverage.

[0217] Due to the different mixing ratios of the concentrate and water, the amount of water used is greater than the amount of concentrate. Therefore, as shown in Figure 30, in some embodiments, given the limited overall space, the volume of the water tank 121 is greater than the volume of the feed tank 110. This balances the frequency of adding water and concentrate, improving the user experience.

[0218] As shown in Figures 32 and 33, in another embodiment, the liquid supply assembly 120 includes a valve 123 and a water tank 124. The valve 123 includes an inlet 1231 and an outlet 1232. One end of the water tank 124 is connected to the outlet 1232, and the other end is connected to a second inlet 1322. The inlet 1231 can be connected to an external water source. Thus, when a user uses the beverage making device 100 to make a beverage, the valve 123 opens, and external water enters the water tank 124 through the inlet 1231 and outlet 1232 of the valve 123. The water in the water tank 124 enters the mixing chamber 131 through the second inlet 1322 and mixes with the concentrate in the mixing chamber 131 to make a beverage. The water in the water tank 124 is kept in a refrigerated environment, which also makes the beverage taste better. In addition, using an external water source makes it easier to add water to the water tank 124, improving the user experience.

[0219] Furthermore, since water tank 124 uses an external water source, there is no concern about water shortage compared to water box 121. Therefore, as shown in Figure 30, in some embodiments, given the limited overall space, the volume of the feed box 110 using an external water source is larger than the volume of the feed box 110 using water box 121. Thus, the beverage preparation device 100 using an external water source can reduce the frequency of adding concentrate, thereby improving the user experience.

[0220] As shown in Figures 30 and 32, in some embodiments, the feed box 110 further includes a first cover 113, and the water box 121 includes a second cover 1213. A first interface 112 is located on the side wall of the feed box 110 and close to the first cover 113, and a second interface 1212 is located on the side wall of the water box 121 and close to the second cover 1213. Thus, when the concentrate in the feed box 110 and the water in the water box 121 are used up, the feed box 110 and the water box 121 can be disassembled, and the first cover 113 and the second cover 1213 can be opened to add concentrate and water, respectively. By placing the first interface 112 and the second interface 1212 close to the cover, that is, by positioning the first interface 112 and the second interface 1212 at the top of the feed box 110 and the water box 121, leakage of the feed box 110 and the water box 121 when they are full of concentrate and water can be prevented.

[0221] To facilitate users in determining the amount of concentrate and water in the ingredient container 110 and water container 121 of the beverage preparation device 100, as shown in Figure 30, in some embodiments, the beverage preparation device 100 further includes a housing assembly 180. The housing assembly 180 has a cavity 181, and the ingredient container 110 is located inside the cavity 181. The liquid level in the ingredient container 110 can be observed through the housing assembly 180 and the side walls of the ingredient container 110.

[0222] In some embodiments, the sidewalls of the container 110 are transparent. At least a portion of the sidewall of the housing assembly 180 corresponding to the container 110 is transparent along the width direction of the container 110. This allows the user to observe the amount of concentrate remaining in the container 110 through the transparent sidewalls of the housing assembly 180, making it easier for the user to determine when to add concentrate, avoiding insufficient liquid during beverage preparation, and improving the user experience.

[0223] As shown in Figures 35 and 36, in some other embodiments, the beverage making apparatus 100 further includes a housing assembly 180, which has a cavity 181, and a water tank 121 is located inside the cavity 181. The liquid level of the water tank 121 can be observed through the sidewalls of the housing assembly 180 and the water tank 121.

[0224] In some embodiments, the sidewalls of the water tank 121 are transparent. The beverage making apparatus 100 also includes a housing assembly 180, which has a cavity 181 in which the water tank 121 is located. At least a portion of the sidewall of the housing assembly 180 corresponding to the water tank 121 is transparent along the width direction of the water tank 121. Thus, the user can observe the water level in the water tank 121 through the transparent sidewall of the housing assembly 180, making it easier for the user to better judge when to add water, avoiding water shortage during beverage making, and improving the user experience.

[0225] It should be noted that the width direction of the material box 110 and the water box 121 is the X direction as shown in Figure 30.

[0226] Of course, referring back to Figures 28, 31, and 33, in some embodiments, the beverage making apparatus 100 further includes a liquid level detection component 190. The liquid level detection component 190 is respectively disposed on the side walls of the water tank 121 and the ingredient tank 110, and the height of the liquid level detection component 190 along the direction of gravity is greater than the height of the bottom wall of the water tank 121 and the ingredient tank 110 along the direction of gravity, in order to detect the liquid level of the water tank 121 and the ingredient tank 110. Thus, the user can know through the liquid level detection component 190 whether the liquid level of the water tank 121 and the ingredient tank 110 is too low, thereby promptly reminding the user to add concentrate or water, preventing the beverage making apparatus 100 from running out of liquid during beverage making, thereby improving the user experience.

[0227] It should be noted that the liquid level detection component 190 can be implemented in various ways, including using a capacitive sensor, etc.

[0228] Researchers have discovered in practice that users not only demand flavored beverages but also tasteless ice water. Based on this, as shown in Figures 30 and 32, in some embodiments, the beverage making apparatus 100 further includes a valve assembly 140, which includes a third inlet 141, a second outlet 142, and a third outlet 143. The third inlet 141 is connected to both the second outlet 142 and the third outlet 143. The third inlet 141 is connected to the liquid supply assembly 120. One of the second outlet 142 and the third outlet 143 is connected to the liquid outlet 1010, and the other is connected to the second inlet 1322. Thus, when a user uses the beverage making apparatus 100 and needs to make a beverage, the valve assembly 140 is controlled to connect the inlets of the liquid supply assembly 120 and the mixing assembly 130, allowing the water and concentrate in the liquid supply assembly 120 to mix in the mixing chamber 131 to make a beverage. If the user needs chilled water, the control valve assembly 140 connects the liquid supply assembly 120 and the liquid outlet 1010, so that the chilled water from the liquid supply assembly 120 flows directly out through the liquid outlet 1010 of the distributor 3130 to provide chilled water to the user.

[0229] It should be noted that the valve assembly 140 can be implemented in various ways, including a selector valve, a one-inlet two-outlet solenoid valve, etc.

[0230] It should be noted that the connection between one of the second outlet 142 and the third outlet 143 and the liquid outlet 1010, and the connection between the other and the second inlet 1322, includes: the second outlet 142 being connected to the liquid outlet 1010, and the third outlet 143 being connected to the second inlet 1322. Alternatively, the second outlet 142 being connected to the second inlet 1322, and the third outlet 143 being connected to the liquid outlet 1010.

[0231] As shown in Figures 30 and 32, in some embodiments, the second outlet 142 is connected to the liquid outlet 1010, and the third outlet 143 is connected to the second inlet 1322. The beverage preparation apparatus 100 also includes a three-way valve 107, to which the first outlet 1333, the second outlet 142, and the liquid outlet 1010 are respectively connected. This allows the beverage flowing from the first outlet 1333 and the ice water flowing from the second outlet 142 to flow out from the liquid outlet 1010 through the three-way valve 107. Using the three-way valve 107 simplifies the water path of the beverage preparation apparatus 100, which is beneficial for miniaturizing the beverage preparation apparatus 100.

[0232] Researchers also discovered in practice that when liquid flows through the water path of the beverage preparation device 100, the liquid in the water flow may flow back into the feed container 110 or the water tank 121 or water container 124 of the liquid supply assembly 120, causing contamination of the concentrate in the feed container 110 or the water in the liquid supply assembly 120.

[0233] Based on this, as shown in Figures 30 and 32, in some embodiments, the second outlet 142 is connected to the liquid outlet 1010, and the third outlet 143 is connected to the second inlet 1322. The beverage making device 100 also includes a first check valve 108, through which the second outlet 142 is connected to the liquid outlet 1010. Thus, when a user uses the beverage making device 100, the beverage can only flow from the second outlet 142 into the first check valve 108 and to the liquid outlet 1010 in the water path, and cannot flow back to the liquid supply assembly 120 through the second outlet 142, thus avoiding contamination of the water source.

[0234] As shown in Figures 30 and 32, in one embodiment, a first one-way valve 108 is connected between the second outlet 142 and the three-way valve 107. Thus, when a user uses the beverage making device 100 to make a beverage, the beverage flowing from the first outlet 1333 of the mixing component 130, upon passing through the three-way valve 107, will not flow to the second outlet 142 due to the action of the first one-way valve 108, preventing backflow to the liquid supply component 120 and contamination of the water source.

[0235] As shown in Figure 30, in some embodiments, the beverage preparation apparatus 100 further includes a second one-way valve 109. The feed container 110 is connected to the first inlet 1341 via the second one-way valve 109. Thus, when a user uses the beverage preparation apparatus 100, the beverage can only flow from the feed container 110 to the first inlet 1341 through the second one-way valve 109 in the water path, and cannot flow back to the feed container 110, thus avoiding contamination of the concentrate.

[0236] As shown in Figures 30 and 32, in some embodiments, the height of the outlet 1010 along the direction of gravity is greater than the height of the first interface 112 along the direction of gravity.

[0237] As shown in Figures 30 and 32, in some other embodiments, the height of the outlet 1010 along the direction of gravity is greater than the height of the second interface 1212 along the direction of gravity.

[0238] Thus, the height of the liquid outlet 1010 is designed to be greater than the height of the first interface 112 and / or the second interface 1212, thereby avoiding the siphoning phenomenon between the liquid outlet 1010 and the material box 110 and / or the water box 121.

[0239] It should be noted that the height of the liquid outlet 1010 being greater than the height of the first interface 112 and / or the second interface 1212 includes: the height of the liquid outlet 1010 being greater than the height of the first interface 112, the height of the liquid outlet 1010 being greater than the height of the second interface 1212, and the height of the liquid outlet 1010 being greater than the height of both the first interface 112 and the second interface 1212.

[0240] It should be noted that the direction of gravity is the Z direction as shown in Figures 30 and 32.

[0241] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0242] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this patent disclosure. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
