Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to refrigerator doors. Background Art

[0002] The refrigerator's door-mounted ice-making system consists of an ice-making chamber located in the door, an ice maker inside the chamber, and an ice storage bin. The door-mounted ice-making system draws cold air from the refrigerator cabinet into the ice-making chamber, lowering the chamber's temperature and freezing water into ice cubes. During this process, the ice maker's ice tray is filled with water, which absorbs a significant amount of cold air to transform into ice. This process requires concentrating the cold air in the ice tray for the fastest ice production.

[0003] However, when the refrigerant fluid introduced into the ice-making chamber by the refrigerator body flows over the ice trays, it flows in at a constant speed from the fluid inlet of the ice-making chamber. The ice trays near the fluid inlet will exchange heat with the refrigerant fluid in turn. As the refrigerant fluid moves toward the fluid outlet, the temperature of the refrigerant fluid gradually rises. This situation causes the refrigerant fluid corresponding to the ice trays near the fluid inlet to be cold and freeze first, while the refrigerant fluid corresponding to the ice trays near the fluid outlet is hotter and freezes slower. As a result, the freezing time of the ice trays along the refrigerant fluid inlet to the refrigerant fluid outlet gradually increases, thereby prolonging the overall ice-making time. Summary of the Invention

[0004] Based on this, it is necessary to provide a refrigerator door to address the technical problem that the freezing time gradually becomes longer at different positions of the entire ice tray along the refrigeration fluid inlet to the refrigeration fluid outlet.

[0005] The present application provides a refrigerator door, comprising:

[0006] a door body, wherein the door body is provided with an ice-making chamber, the ice-making chamber having a fluid inlet and a fluid outlet, the fluid inlet being configured to introduce a refrigeration fluid into the ice-making chamber;

[0007] an ice maker, the ice maker being disposed in the ice making chamber, the ice maker comprising a drive mechanism and a liquid container, the drive mechanism being in driving connection with the liquid container, the liquid container being configured to contain ice-making liquid;

[0008] An air control device is provided in the ice-making chamber and is arranged opposite to the liquid container. The air control device is configured to control the refrigeration fluid to contact the ice-making liquid at different positions of the liquid container at different flow rates.

[0009] In the above embodiment, based on the differences in relative distances between different locations in the liquid container and the fluid inlet, the air control device controls the flow of cold air to exchange heat with different locations of the ice-making liquid at different flow rates. This increases the cold air flow rate and compensates for the decrease in cold air temperature. For example, locations near the fluid inlet in the liquid container experience lower cold air temperatures and lower cold air flow rates, allowing the ice-making liquid at corresponding locations to freeze quickly. Locations gradually farther from the fluid inlet in the liquid container experience relatively higher cold air temperatures and relatively higher cold air flow rates. By regulating the cold air temperature through the cold air flow rate, the ice-making liquid at different locations throughout the ice tray of the liquid container, from the refrigeration fluid inlet to the refrigeration fluid outlet, achieves substantially the same freezing time, thus resolving the problem of varying freezing rates for the ice-making liquid at different locations in the liquid container.

[0010] In one embodiment, the wind control device is configured to control the refrigeration fluid to gradually increase its flow rate starting from the fluid inlet entering the ice-making chamber, thereby allowing the refrigeration fluid to flow through the ice-making liquid at different positions of the liquid container at different flow rates.

[0011] In one embodiment, the wind control device includes a wind control element, the wind control element having a wind control surface, the wind control element is located above the liquid container, and the wind control surface faces the liquid container;

[0012] Wherein, along the flow direction of the refrigerant fluid, the distance between different positions of the wind control surface and the liquid holding device gradually decreases.

[0013] In the above embodiment, different positions of the wind control surface have different distances relative to the liquid container, thereby forming different compression effects on the cold air. For example, the volume of the cold air becomes smaller and smaller when it flows from right to left, and the volume of the cold air is gradually compressed, so that the flow rate of the cold air gradually increases due to the volume compression.

[0014] In one embodiment, the wind control surface is provided with a plurality of steps, wherein along the flow direction of the refrigerant fluid, the distance between the plurality of steps and the liquid container gradually decreases; or,

[0015] The wind control surface is configured as an inclined plane, wherein the distance between the inclined plane and the liquid container gradually decreases along the flow direction of the refrigerant fluid; or

[0016] The wind control surface is configured as an inclined curved surface, wherein along the flow direction of the refrigerant fluid, the distance between the inclined curved surface and the liquid container gradually decreases.

[0017] In one embodiment, a side of the wind control element closer to the fluid inlet is a starting side, and a side of the wind control element farther from the fluid inlet is an end side, wherein the distance between the starting side of the wind control element and the liquid level of the ice-making liquid in the liquid container is an air inlet distance, and the distance between the end side of the wind control element and the liquid level of the ice-making liquid in the liquid container is an air outlet distance, and the height difference between the height of the air inlet distance and the height of the air outlet distance is greater than 25 mm and less than 35 mm; and / or,

[0018] The angle between the wind control surface of the wind control element and the liquid surface of the ice-making liquid in the liquid container is a fluid angle, and the fluid angle is greater than 10 degrees and less than 30 degrees.

[0019] In the above embodiment, the height of the air inlet spacing differs from the height of the air outlet spacing by 25 mm to 35 mm, and the fluid angle is set between 10 degrees and 30 degrees. In this way, the temperature of the cold air gradually increases from right to left. At the same time, the flow rate of the cold air also gradually increases from right to left. The height difference and its rate of change can make the flow rate of the cold air better coordinate the increase in the temperature of the cold air, thereby making the freezing time of the ice cube trays in different positions tend to be consistent.

[0020] In one embodiment, the wind control device includes a blocking element, which is arranged in the ice-making chamber. The blocking element is configured to enclose a diversion space together with the inner wall of the ice-making chamber. The fluid inlet is connected to the diversion space, and the outlet of the diversion space is toward the liquid container.

[0021] In the above embodiment, the outlet of the guide space is configured to face the liquid container, so that the cold air of the refrigerator body can flow toward the liquid container in a predictable manner after entering the ice-making chamber, thereby concentrating the cold air toward the liquid container, thereby speeding up the ice-making rate.

[0022] In one embodiment, the outlet of the flow guiding space is located below the flow guiding space, and the liquid container is located below the flow guiding space.

[0023] In one embodiment, the ice-making chamber has at least a first inner wall, a second inner wall and a third inner wall, the third inner wall is connected between the first inner wall and the second inner wall, the fluid inlet is opened on the first inner wall, and the blocking element is configured to enclose the diversion space together with the first inner wall, the second inner wall and the third inner wall of the ice-making chamber.

[0024] In one embodiment, the blocking element includes a blocking main body and a first side plate and a second side plate located on both sides of the blocking main body; a first gap is defined between the first end of the ice maker and the first inner wall, and a second gap is defined between the second end of the ice maker and the second inner wall;

[0025] The outer side surface of the ice maker is configured to be away from the third inner wall, the first side plate is configured to block the first gap on the outer side surface of the ice maker, and the second side plate is configured to block the second gap on the outer side surface of the ice maker.

[0026] In the above embodiment, based on the design of at least one of the first gap and the second gap, the cold air entering the guide space through the fluid inlet of the refrigerator door can first be stored to a certain extent in the guide space to achieve accumulation of cold energy. By continuously injecting cold energy into the guide space, the air pressure in the guide space will be in a positive pressure state, and the outlet of the guide space will face the liquid container. Therefore, under the positive pressure state, the cold energy will preferentially pass through the liquid container through at least one of the first gap and the second gap, thereby improving the ice making efficiency.

[0027] In one embodiment, there is an outer gap between the outer side of the ice maker and the blocking main body, and the guide space in the ice making chamber is connected to the space below the liquid container in the ice making chamber through the outer gap; and / or,

[0028] An inner gap is defined between the inner side surface of the ice maker and the third inner wall, and the flow guiding space in the ice making chamber is communicated with the space below the liquid container in the ice making chamber via the outer gap.

[0029] In the above embodiment, based on the design of at least one of the above-mentioned outer gap and inner gap, the cold air entering the guide space through the fluid inlet of the refrigerator door can first be stored to a certain extent in the guide space to achieve accumulation of cold energy. By continuously injecting cold energy into the guide space, the air pressure in the guide space will be in a positive pressure state, and the outlet of the guide space will face the liquid container. Therefore, under the positive pressure state, the cold energy will preferentially pass through the liquid container through at least one of the outer gap and the inner gap, thereby improving the ice making efficiency.

[0074] The present application provides a refrigerator, which includes a refrigerator body and a refrigerator door, wherein the refrigerator door is openably and closably arranged on the refrigerator body. Figures 1 to 23As shown, the present application provides a refrigerator door, which includes a door body 1000, an ice maker 2000 and a wind control device 3000, wherein the door body 1000 is the main structure of the refrigerator door, and an ice-making chamber 1001 is arranged inside the door body 1000. The ice-making chamber 1001 is a chamber structure formed inside the door body 1000. The size, structure, etc. of the chamber structure can be designed according to the layout of structures such as the ice maker 2000 and the wind control device 3000, and are not limited here.

[0075] See Figure 4 As shown, ice-making chamber 1001 has a fluid inlet 1002 and a fluid outlet 1003. Fluid inlet 1002 and fluid outlet 1003 communicate with the interior of ice-making chamber 1001. Fluid (e.g., cold air) can be input through fluid inlet 1002, enter ice-making chamber 1001, and then be output through fluid outlet 1003, thereby achieving a fluid flow trajectory through ice-making chamber 1001. Fluid inlet 1002 and fluid outlet 1003 are located on the inner side of door body 1000. The inner side of door body 1000 is the side where door body 1000 is pivotally connected to the refrigerator body, i.e., the inner side is located closer to the refrigerator body.

[0076] The interior of the refrigerator body utilizes cold air to refrigerate or freeze food. When the door body 1000 is closed relative to the refrigerator body, the fluid inlet 1002 and the fluid outlet 1003 of the door body 1000 are both connected to the interior of the refrigerator body, thereby enabling the fluid inlet 1002 to be configured to introduce a refrigeration fluid 10 into the ice-making chamber 1001. In this case, the refrigeration fluid 10 is the cold air in the refrigerator body used to refrigerate or freeze food. The cold air can flow from the interior of the refrigerator body into the ice-making chamber 1001 through the fluid inlet 1002, and then, after being used to make ice in the ice-making chamber 1001, it flows out of the fluid outlet 1003 of the door body 1000 and flows back into the refrigerator body, thus forming a cold air flow cycle, forming a flow trajectory of the cold air through the ice-making chamber 1001, and continuously drawing cold air from the refrigerator body for the purpose of making ice in the ice-making chamber 1001.

[0077] Ice maker 2000 is located in ice making chamber 1001 and includes a liquid container 2100 for holding ice-making liquid. The structure, shape, and dimensions of liquid container 2100 can be designed based on ice making requirements. For example, liquid container 2100 can be an ice tray commonly used in refrigerators. The ice tray can be configured with a number of ice cube trays 2101 arranged in a predetermined pattern. Ice cube trays 2101 are filled with a suitable ice-making liquid (such as water or a beverage) to utilize cold air to make ice. The cold air lowers the temperature within ice making chamber 1001, freezing the ice-making liquid into ice cubes, thereby achieving ice making. During this process, the ice-making liquid absorbs a large amount of cold energy to form ice cubes. This process requires concentrating the cold energy at the location of liquid container 2100 to achieve the fastest ice making speed.

[0078] Based on the above mentioned flow trajectory of the cold air, refer to Figures 5 to 7 In the orientation shown, after the cold air enters the ice-making chamber 1001 from the fluid inlet 1002, the cold air will flow horizontally above the liquid container 2100, and pass through different positions of the liquid container 2100 in sequence during the flow, that is, it will first contact the position of the liquid container 2100 closest to the fluid inlet 1002. As other positions in the liquid container 2100 gradually move away from the fluid inlet 1002, the cold air will gradually pass through other positions in the liquid container 2100 that are gradually farther away from the fluid inlet 1002.

[0079] Therefore, after cold air enters the ice-making chamber 1001 at a uniform speed from the fluid inlet 1002, the ice-making liquid near the fluid inlet 1002 in the liquid container 2100 (or the ice tray 2101 near the fluid inlet 1002) preferentially exchanges heat with the cold air. As the cold air flows, the temperature of the cold air gradually rises due to this continuous heat exchange. This ensures that the cold air in contact with the ice-making liquid near the fluid inlet 1002 in the liquid container 2100 is relatively cool, causing it to freeze first. Meanwhile, the cold air in contact with the ice-making liquid further away from the fluid inlet 1002 in the liquid container 2100 is relatively hotter. Therefore, as other locations in the liquid container 2100 move further away from the fluid inlet 1002, the rate of freezing gradually decreases.

[0080] In order to solve the problem of different freezing speeds of ice-making liquid at different positions in the liquid container 2100, refer to Figures 5 to 7As shown, the door body 1000 is also provided with the aforementioned air control device 3000. The air control device 3000 can be configured to control the flow rate of the refrigerant fluid 10 to exchange heat with different locations of the ice-making liquid at different flow rates. Therefore, based on the differences in the relative distances between different locations in the liquid container 2100 and the fluid inlet 1002, the air control device 3000 controls the flow of cold air at different flow rates to exchange heat with different locations of the ice-making liquid. This increased cold air flow rate can compensate for the decrease in cold air temperature.

[0081] The air control device 3000 can be configured to gradually increase the flow rate of the refrigerant fluid 10, thereby causing the refrigerant fluid 10 to flow through different locations of the ice-making liquid at different flow rates. The air control device 3000 can also be configured to gradually increase the flow rate of the refrigerant fluid 10 in a direction away from the fluid inlet 1002. When the air control device 3000 controls factors such as the flow direction and flow rate of the refrigerant fluid 10 (cold air), the control can be based on the placement of the liquid container 2100 of the ice-making machine 2000 in the ice-making chamber 1001 and the relative position of the liquid container 2100 of the ice-making machine 2000 with respect to the fluid inlet 1002. Those skilled in the art can design the control based on actual conditions, and this is not limited here.

[0082] For example, as different positions in the liquid container 2100 gradually move away from the fluid inlet 1002, the cold air flow rate at the corresponding positions in the liquid container 2100 is targetedly increased, and the increase in the cold air flow rate is used to compensate for the lack of cold air temperature. That is, the position close to the fluid inlet 1002 in the liquid container 2100 obtains a lower cold air temperature and a lower cold air flow rate, and the ice-making liquid at the corresponding position can achieve rapid ice making. The position gradually away from the fluid inlet 1002 in the liquid container 2100 will gradually obtain a relatively high cold air temperature and a relatively high cold air flow rate. The cold air temperature is coordinated by the cold air flow rate, so that the ice-making liquid at different positions in the liquid container 2100 can be frozen synchronously as much as possible, thereby solving the problem of different freezing speeds of the ice-making liquid at different positions in the liquid container 2100.

[0083] Regarding the control method of the wind control device 3000 controlling the refrigeration fluid 10 to flow through different positions of the ice-making liquid at different flow rates, the wind control device 3000 can be implemented in a number of ways, such as an inclined surface structure, a difference in aperture, etc., which are not limited here. For example, in one embodiment, the wind control device 3000 may include a wind control element 3100 and other components for mounting the wind control element 3100 on the door body 1000, such as a fixing plate, a fixing frame, a fixing base, and bolts, buckles and other components. Those skilled in the art can mount the wind control element 3100 on the door body 1000 in an appropriate manner. Therefore, those skilled in the art can select the components according to their needs, which are not limited here.

[0084] Among them, the wind control element 3100 can adopt any structure such as plate-shaped, block-shaped, etc., wherein one side of the wind control element 3100 can have a wind control surface 3110, and the wind control surface 3110 is configured to be set toward the liquid container 2100, so that the wind control requirements can be achieved through the inclined structure.

[0085] In addition, the wind control element 3100 can also be provided with a number of wind control holes with different positions and different apertures. Each wind control hole can be used to pass cold air with different wind force and flow rate. Therefore, by distributing a number of wind control holes with different positions and different apertures, it is possible to apply cold air with different flow rates toward different positions of the ice-making liquid, thereby making the refrigerant fluid 10 flow through different positions of the ice-making liquid at different flow rates.

[0086] Those skilled in the art may design the wind control element 3100 and the specific wind control method in an appropriate manner, which is not limited here.

[0087] Along the direction of the flow of the refrigerant fluid 10, for example Figure 5 In the transverse flow direction from right to left shown in FIG, the air control surface 3110 can be configured to gradually slope toward the liquid container 2100, thereby forming an inclined surface that gradually slopes downward from right to left. In one embodiment, the air control surface 3110 can be configured to gradually slope toward the liquid container 2100 in a direction gradually away from the fluid inlet 1002, and the air control element 3100 can be located above the liquid container 2100.

[0088] Based on the design of the wind control surface 3110, the cold air flows along Figure 5 As the cold air flows from right to left within the ice making chamber 1001, it gradually contacts different locations of the air control surface 3110, which are closer and closer to the liquid container 2100, along the direction of flow. At this point, different locations of the air control surface 3110 have different distances from the liquid container 2100, resulting in different compression effects on the cold air. For example, the volume of the cold air decreases as it flows from right to left, and the volume of the cold air is gradually compressed, causing the flow rate of the cold air to gradually increase due to the compressed volume, thus gradually increasing the flow rate of the cold air as it flows.

[0089] In one embodiment, under the action of the wind control surface 3110, the cold air is blown along the Figure 5The direction shown gradually increases the flow rate from right to left. When the cold air gradually exchanges heat with the ice-making liquid at different positions in the liquid container 2100 from right to left, the temperature of the cold air gradually increases from right to left, but the flow rate of the cold air also gradually increases from right to left. In this way, the increase in the cold air temperature can be compensated by the flow rate of the cold air, and finally the ice-making liquid at different positions in the liquid container 2100 can be frozen synchronously, and the freezing speed from right to left is consistent.

[0090] The wind control surface 3110 can be tilted in a variety of ways. For example, in one embodiment, the wind control surface 3110 can be provided with a plurality of steps 3111, wherein the steps 3111 gradually approach the liquid container 2100 as the direction gradually moves away from the fluid inlet 1002. The tilt of the wind control surface 3110 is achieved by the distribution of the steps 3111. Alternatively, the wind control surface 3110 can be configured as an inclined plane, wherein the inclined plane gradually tilts toward the liquid container 2100 as the direction gradually moves away from the fluid inlet 1002. Alternatively, the wind control surface 3110 can be configured as an inclined curved surface, wherein the inclined curved surface gradually tilts toward the liquid container 2100 as the direction gradually moves away from the fluid inlet 1002.

[0091] The actual regulating effect of the wind control surface 3110 on the cold air flow rate can be verified through the following specific comparative examples.

[0092] See Figure 9 As shown, there are ten ice trays 2101 in the liquid container 2100, and the ten ice trays 2101 are divided into two horizontal rows, the upper row and the lower row each having five ice trays 2101, and the five ice trays 2101 in one row (for example, the five horizontal ice trays 2101 located on the upper side, or the five horizontal ice trays 2101 located on the lower side) are numbered from right to left as ice tray No. 1 2101, ice tray No. 2 2101, ice tray No. 3 2101, ice tray No. 4 2101 and ice tray No. 5 2101.

[0093] At this time, the cold air flows from right to left and can pass through ice cube tray No. 1 2101, ice cube tray No. 2101, ice cube tray No. 3 2101, ice cube tray No. 4 2101 and ice cube tray No. 5 2101 in sequence, and exchange heat with the ice-making liquid in ice cube tray No. 1 2101, ice cube tray No. 2101, ice cube tray No. 3 2101, ice cube tray No. 4 2101 and ice cube tray No. 5 2101 in sequence.

[0094] When the wind control device 3000 is not provided:

[0095] See Figure 24As shown in Data Table 1 (temperature unit: degrees Celsius), there are seven sets of experimental data in Data Table 1. The seven sets of experimental data all prove that when cold air flows from right to left, the temperature of the cold air gradually increases as it passes through ice cube tray No. 1 2101 , ice cube tray No. 2 2101 , ice cube tray No. 3 2101 , ice cube tray No. 4 2101 , and ice cube tray No. 5 2101 .

[0096] See Figure 25 As shown in Data Table 2 (time unit: minutes), there are five sets of experimental data. All five sets of experimental data prove that when cold air flows from right to left, the time it takes for the temperature of ice tray No. 1 2101, ice tray No. 2 2101, ice tray No. 3 2101, ice tray No. 4 2101, and ice tray No. 5 2101 to reach -12 degrees Celsius gradually increases, resulting in a longer freezing time for the ice cubes.

[0097] When the above-mentioned wind control device 3000 is set:

[0098] Taking the structure of the wind control surface 3110 with a plurality of steps 3111 as an example, refer to Figure 26 As shown in Data Table 3 (time unit: minute), Data Table 3 contains five sets of experimental data. All five sets of experimental data prove that when cold air flows from right to left, although the time taken for the temperatures of ice tray No. 1 2101, ice tray No. 2 2101, ice tray No. 3 2101, ice tray No. 4 2101, and ice tray No. 5 2101 to reach -12 degrees Celsius is slightly different, compared with the experimental data in Data Table 2 above, it can be proved that the addition of wind control device 3000 can make the time taken for the temperatures of ice tray No. 1 2101, ice tray No. 2 2101, ice tray No. 3 2101, ice tray No. 4 2101, and ice tray No. 5 2101 to reach -12 degrees Celsius basically consistent, thereby ensuring that the ice cubes freeze in a similar time and improving the uniformity of ice freezing.

[0099] At least some of the ice trays 2101 can be configured to have the same liquid capacity. Therefore, in one embodiment, only some of the ice trays 2101 can have the same liquid capacity, or all of the ice trays 2101 can have the same liquid solution. In this case, the actual volume of ice-making liquid contained in different ice trays 2101 also factors influencing ice-making consistency. Therefore, the air control device 3000 can also be configured to control the refrigeration fluid 10 to have heat exchange contact with different ice trays 2101 of the liquid container 2101 at different flow rates. For example, when the actual volume of ice-making liquid in the ice tray 2101 is large, the flow rate of the cold air is increased accordingly, thereby utilizing the increased flow rate of the cold air to compensate for the slow freezing caused by the large volume of ice-making liquid.

[0100] In one embodiment, several ice trays 2101 can be set to have the same liquid holding capacity, so that the same capacity of ice-making liquid can be held in all ice trays 2101. At this time, the above-mentioned wind control device 3000 can be configured to control the refrigeration fluid 10 to gradually increase the flow rate in the direction gradually away from the fluid inlet 1002, thereby exchanging heat with different ice trays 2101 of the liquid holding container 2100 at a gradually increasing flow rate.

[0101] As can be seen from the above, the ice-making liquid needs to absorb a large amount of cold energy to form ice cubes. This process requires concentrating the cold energy at the position of the liquid container 2100 to achieve the fastest ice making. Therefore, in one embodiment, the wind control device 3000 may include a blocking element 3200, which is arranged in the ice-making chamber 1001. With the help of the inner wall of the ice-making chamber 1001, the blocking element 3200 can be configured to enclose a diversion space 1004 together with the inner wall of the ice-making chamber 1001. The fluid inlet 1002 is connected to the diversion space 1004, and the fluid inlet 1002 can be used to divert the cold air of the refrigerator body into the diversion space 1004. Then, the outlet of the diversion space 1004 is configured to face the liquid container 2100, so that the cold air of the refrigerator body can flow toward the liquid container 2100 in a predictable manner after entering the ice-making chamber 1001, thereby realizing the concentration of cold air toward the liquid container 2100, thereby accelerating the ice-making rate.

[0102] Also, continue reading Figure 9 As shown, in one embodiment, the ice-making chamber 1001 comprises at least a first inner wall 1010, a second inner wall 1020, and a third inner wall 1030. This provides a preliminary illustration of one design for the inner wall of the ice-making chamber 1001. In this embodiment, the third inner wall 1030 is connected between the first inner wall 1010 and the second inner wall 1020. The first inner wall 1010, the second inner wall 1020, and the third inner wall 1030 collectively form a generally concave wall surface, i.e., a three-side wall surface. The fluid inlet 1002 is provided in the first inner wall 1010. In this embodiment, the blocking element 3200 can be used to block the notch in the concave wall surface, so that the blocking element 3200 blocks the open side of the three side walls formed by the first inner wall 1010, the second inner wall 1020, and the third inner wall 1030.

[0103] Therefore, if Figure 8 and Figure 9 As shown, in the ice making chamber 1001, the blocking element 3200 can be used together with the first inner wall 1010, the second inner wall 1020 and the third inner wall 1030 of the ice making chamber 1001 to enclose a Figure 8 The diversion space 1004 in the shown area. Figure 8As shown, in one embodiment, the outlet of the flow diversion space 1004 is located below the flow diversion space 1004, and the liquid container 2100 is located below the flow diversion space 1004. In addition, the relative position relationship between the outlet of the flow diversion space 1004 and the liquid container 2100 can be further designed according to actual needs. For example, the outlet of the flow diversion space 1004 and the liquid container 2100 can be arranged horizontally or inclined in the ice making chamber 1001, etc., which is not limited here.

[0104] It should be noted that, in Figure 8 and Figure 9 In the embodiment shown, since the only outlet of the flow guiding space 1004 faces the liquid container 2100 below, the flow guiding space 1004 is a closed structure except for the outlet facing downward and the position connected to the fluid inlet 1002. Figure 8 and Figure 9 As shown, the blocking element 3200 and the first inner wall 1010, the second inner wall 1020 and the third inner wall 1030 of the ice making chamber 1001 together enclose a Figure 8 The guide space 1004 in the area shown is Figure 9 For the ice making chamber 1001 whose interior space is roughly square, the upper inner wall (see FIG. 1 ) of the ice making chamber 1001 connected to the first inner wall 1010, the second inner wall 1020 and the third inner wall 1030 is Figure 8 ), which also encloses one side inner wall of the guide space 1004. Those skilled in the art can enclose the guide space 1004 according to the actual structure of the ice making chamber 1001, and are not limited here.

[0105] Continue reading Figure 9 As shown, in one embodiment, the blocking element 3200 may include a blocking main plate 3210 and a first side plate 3220 and a second side plate 3230 located on both sides of the blocking main plate 3210. Figure 9 The right end shown is the first end of the ice maker 2000, and the left end is the second end of the ice maker 2000. At this time, there may be a first gap 3201 between the first end of the ice maker 2000 and the first inner wall 1010, and there may be a second gap 3202 between the second end of the ice maker 2000 and the second inner wall 1020. At the same time, it is limited that the outer side of the ice maker 2000 is configured to be away from the side of the third inner wall 1030, that is, Figure 9 The lower side of the ice maker 2000 in FIG. 2 is configured to be close to the side of the third inner wall 1030, that is, Figure 9At this time, the first side plate 3220 can be configured to block the outside of the first gap 3201 on the outer side of the ice maker 2000, and the second side plate 3230 can be configured to block the outside of the second gap 3202 on the outer side of the ice maker 2000.

[0106] Continue reading Figure 9 As shown, in one embodiment, the outer side surface of the ice maker 2000 may have an outer gap 3203 between it and the blocking main body 3210, and the guide space 1004 in the ice making chamber 1001 may be connected to the space below the liquid container 2100 in the ice making chamber 1001 through the outer gap 3203, thereby allowing the cold air in the guide space 1004 to flow to the bottom of the ice maker 2000 through the outer gap 3203, so that the cold air is in heat exchange contact with the bottom of the liquid container 2100. Similarly, an inner gap 3204 may be provided between the inner side surface of the ice maker 2000 and the third inner wall 1030, and the guide space 1004 in the ice making chamber 1001 may be connected to the space below the liquid container 2100 in the ice making chamber 1001 through the outer gap 3203, thereby allowing the cold air in the guide space 1004 to flow to the bottom of the ice maker 2000 through the inner gap 3204, so that the cold air is in heat exchange contact with the bottom of the liquid container 2100.

[0107] Continue reading Figure 8 and Figure 9 As shown, in this embodiment, the first end of the ice maker 2000 is blocked by the first inner wall 1010, the second end of the ice maker 2000 is blocked by the second inner wall, the inner side surface of the ice maker 2000 is blocked by the third inner wall 1030, and the outer side surface of the ice maker 2000 is blocked by the blocking main body 3210. The ice maker 2000 is opposite to the upper inner wall of the ice making chamber 1001 connected to the first inner wall 1010, the second inner wall 1020 and the third inner wall 1030.

[0108] Therefore, in the flow guide space 1004 constructed in the ice making chamber 1001, according to Figure 8 In the orientation shown, the right side of the guide space 1004 is the first inner wall 1010, the left side of the guide space 1004 is the second inner wall 1020, the inner side of the guide space 1004 is the third inner wall 1030, the outer side of the guide space 1004 is the blocking element 3200, the upper side of the guide space 1004 is the upper inner wall of the ice-making chamber 1001 connected to the first inner wall 1010, the second inner wall 1020 and the third inner wall 1030, and the lower side of the guide space 1004 is the ice-making machine 2000, so that the guide space 1004 is roughly a relatively enclosed space enclosed by the above-mentioned first inner wall 1010, the second inner wall 1020, the third inner wall 1030, the blocking element 3200, the upper inner wall and the ice-making machine 2000.

[0109] The airtightness of the flow-guiding space 1004 is not absolutely airtight. This is because there is an outer gap 3203 between the outer side of the ice maker 2000 and the main blocking body 3210, an inner gap 3204 between the inner side of the ice maker 2000 and the third inner wall 1030, a first gap 3201 between the first end of the ice maker 2000 and the first inner wall 1010, and a second gap 3202 between the second end of the ice maker 2000 and the second inner wall 1020. Therefore, the flow-guiding space 1004 in the ice-making chamber 1001 is connected to the space below the liquid container 2100 in the ice-making chamber 1001 via the first gap 3201, second gap 3202, outer gap 3203, and inner gap 3204.

[0110] At this time, the first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204 are also four gaps surrounding the ice maker 2000 (inside, outside, left and right). The first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204 can be at least partially connected or not connected to each other, and can all realize the flow of cold air to the bottom of the liquid container 2100.

[0111] Based on the design of at least one of the above-mentioned first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204, the cold air entering the guide space 1004 through the fluid inlet 1002 of the refrigerator door can first be stored to a certain extent in the guide space 1004 to achieve accumulation of cold energy. By continuously injecting cold energy into the guide space 1004, the air pressure in the guide space 1004 will be in a positive pressure state, and the outlet of the guide space 1004 will face the liquid container 2100. Therefore, under the positive pressure state, the cold energy will preferentially pass through the liquid container 2100 through at least one of the first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204, thereby improving the ice making efficiency.

[0112] Moreover, since the first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204 surround the ice maker 2000 (inside, outside, left and right), all-round cooling of the liquid container 2100 in the ice maker 2000 can be achieved, further improving the ice making efficiency.

[0113] Continue reading Figure 20 As shown, along the flow direction of the refrigerant fluid (i.e., the flow direction from right to left), the distance between different positions of the air control surface 3110 and the liquid container 2100 gradually decreases. Therefore, the distance between the air control element 3100 and the liquid container 2100 is the largest at its rightmost position. The rightmost position of the air control element 3100 is defined as the starting side, as shown in FIG. Figure 20 As shown, the spacing here can be set as the air inlet spacing 3205. At this time, the height of the air inlet spacing 3205 is the largest. At the same time, the distance between the air control element 3100 and the liquid container 2100 is the smallest at its leftmost position. The air control element 3100 at its leftmost position is defined as the end side. Figure 20 As shown, the spacing here can be set as the air outlet spacing 3206, and at this time the height of the air outlet spacing 3206 is the smallest.

[0114] It should be noted that when the ice-making liquid in the liquid container 2100 is stable, it has a stable liquid level. In this case, the distance between the starting side of the air control element 3100 and the liquid container 2100 primarily refers to the distance between the starting side of the air control element 3100 and the liquid level of the ice-making liquid in the liquid container 2100. Similarly, the distance between the ending side of the air control element 3100 and the liquid container 2100 also primarily refers to the distance between the ending side of the air control element 3100 and the liquid level of the ice-making liquid in the liquid container 2100.

[0115] Along the flow direction of the refrigerant fluid, the refrigerant fluid (such as cold air) enters the space between the wind control element 3100 and the liquid container 2100 from the air inlet spacing 3205 on the right. Under the action of the air control surface 3110, the refrigerant fluid flows from right to left, and then flows along the air outlet spacing 3206 on the left to the lower side of the liquid container 2100.

[0116] like Figure 20 As shown, if the width of the wind control element 3100 is limited to the starting side to the end side (i.e., the leftmost to the rightmost side), the width of the wind control element 3100 can be limited by factors such as the width design of the refrigerator door, the household refrigerator usage environment, and the width of the household door. Generally, the width of the wind control element 3100 can be limited to between 150mm and 400mm. For example, the width of the wind control element 3100 can be set to different size values ​​such as 150mm, 170mm, 190mm, 210mm, 230mm, 250mm, 270mm, 290mm, 310mm, 330mm, 350mm, 370mm, 390mm, and 400mm. Those skilled in the art can design according to their needs, and this is not limited here.

[0117] The height of the air inlet spacing 3205 is limited by the space inside the refrigerator. If the air inlet spacing 3205 is too high, the refrigerator's air supply and return system will occupy more space, the air inlet pressure will be low, and the air volume at the air inlet spacing 3205 will be small. If the air inlet spacing 3205 is too small, it will cause high air inlet resistance, high air inlet pressure, high air velocity, short heat exchange time between the cold air and the ice tray, and low ice making efficiency.

[0118] Therefore, after extensive testing and verification, the height of the air inlet spacing 3205 can be limited to between 35 mm and 65 mm. For example, the height of the air inlet spacing 3205 can be 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm, 65 mm, and other different values. Those skilled in the art can design according to their needs and are not limited here.

[0119] Taking the example of a structure with several steps 3111 on the air control surface 3110, the height of the air outlet gap 3206 is the height of the step at the end (leftmost) side of the air control surface 3110 relative to the liquid container 2100. Since the cold air needs to turn 90 degrees from this step and be blown downward, the height of the step at the end (leftmost) side needs to be within a reasonable range. If the height of this step is too low, the air outlet gap 3206 will be blocked, preventing the cold air from escaping in time and reducing the amount of air inlet and outlet.

[0120] The height of the air outlet spacing 3206 can be limited to 10 mm to 35 mm. For example, the height of the air outlet spacing 3206 can be 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, and other different values. Those skilled in the art can design according to their needs and are not limited here.

[0121] If the width of the wind control element 3100 is between 150 mm and 400 mm, the larger the width of the wind control element 3100, the more drastic the change between the height of the air inlet spacing 3205 and the height of the air outlet spacing 3206, and thus the greater the inclination of the wind control surface 3110. For example, taking a structure in which a plurality of steps 3111 are set on the wind control surface 3110 as an example, the height difference of the plurality of steps 3111 relative to the height of the liquid container 2100 is greater.

[0122] Correspondingly, the smaller the width of the wind control element 3100, the smoother the change between the height of the air inlet spacing 3205 and the height of the air outlet spacing 3206, and thus the smaller the inclination of the wind control surface 3110. For example, taking the structure of providing a plurality of steps 3111 based on the wind control surface 3110 as an example, the height difference of the plurality of steps 3111 relative to the height of the liquid container 2100 is smaller.

[0123] The fan with 125-1500rpm is used as the air source. The relevant test data are as follows: Figure 27 As shown in the table. Among them, the unit of air volume is m 3 / h, the width of the top step is 200mm, the height of the air inlet spacing 3205 is 45mm, the height unit is mm.

[0124] From Figure 27The table shows that when the air outlet gap 3206 is 4mm, 6mm, and 8mm, there is a significant difference in inlet and outlet pressure. In these cases, the inlet pressure is high, and the air is trapped in the confined space formed by the upper step and the ice maker. This slows the flow of cold air, creates significant fan resistance, and results in low overall efficiency.

[0125] When the height of the air outlet spacing 3206 is 35 mm or 40 mm, since the height of the air inlet spacing 3205 is 45 mm, the height of the air inlet spacing 3205 is similar to the height of the air outlet spacing 3206. At this time, the wind resistance of the cold air is relatively small, and the cold air passes quickly over the liquid container 2100. It does not have time to exchange heat with the ice tray of the liquid container 2100 and directly returns to the air duct system, and the overall efficiency is also low.

[0126] Only when the height of the air outlet spacing 3206 is 10mm, 15mm, or 20mm, and the height of the air inlet spacing 3205 differs from the height of the air outlet spacing 3206 by 25mm to 35mm, the cold air is in the enclosed space above the ice maker, and there is a reasonable pressure difference between the air inlet spacing 3205 and the air outlet spacing 3206. The flow speed of the cold air from the left to the right is reasonable, and the heat exchange between the cold air and the ice tray is within a reasonable range. This is more suitable for ice making needs.

[0127] Combined with the above analysis of the impact of the height of the air inlet spacing 3205 and the air outlet spacing 3206 on ice making, the ice-making liquid in the liquid container 2100 has a stable liquid level when it is stable in the liquid container 2100. At this time, the angle between the air control surface 3110 of the air control element 3100 and the liquid level of the ice-making liquid in the liquid container 2100 can be set as the fluid angle 3207.

[0128] Regarding the wind control surface 3110 of the wind control element 3100, although the surface structure of the wind control surface 3110 can be specifically designed according to actual conditions, Figure 20 As shown, if the rightmost position of the wind control element 3100 is defined as the starting side, and the leftmost position of the wind control element 3100 is defined as the end side, then the wind control surface 3110 can be determined based on the plane where the line between the starting side and the end side of the wind control element 3100 is located. Therefore, the fluid angle 3207 is equivalent to the angle between the plane where the line between the starting side and the end side of the wind control element 3100 is located and the plane where the liquid container 2100 is located.

[0129] At this time, the specific structural performance of the fluid angle 3207 can be as follows: Figure 20 As shown, the data statistics of the fluid angle 3207 can be referred to as Figure 28 The table shown.

[0130] As mentioned above, in one embodiment, the width of the wind control element 3100 can be 200 mm, the height of the air inlet spacing 3205 can be designed to be 35 mm to 65 mm, and the height of the air outlet spacing 3206 can be designed to be 10 mm to 35 mm. Figure 28 As shown in the table, after statistical optimization, the preferred value of the fluid angle 3207 at this location can be selected to be 10 to 30 degrees. For example, the fluid angle 3207 can be selected to be 10 degrees, 12 degrees, 14 degrees, 16 degrees, 18 degrees, 20 degrees, 22 degrees, 24 degrees, 26 degrees, 28 degrees, 30 degrees, and other different values. Those skilled in the art can design according to their needs, and this is not limited here.

[0131] In addition, if the width of the wind control element 3100 is selected to other values ​​between 150mm and 400mm, and the height of the air inlet spacing 3205 is designed to be 35mm to 65mm, and the height of the air outlet spacing 3206 is designed to be 10mm to 35mm, based on this design, the fluid angle 3207 can also be selected to be other degree ranges according to design requirements, which is not limited here.

[0132] The cold air enters the space between the wind control element 3100 and the liquid container 2100 from the air inlet spacing 3205 on the right side. After the cold air continuously collides with the several steps 3111 of the wind control surface 3110, the air in the upper part of the space between the wind control element 3100 and the liquid container 2100 will be continuously impacted and reflected by the steps one by one, causing the upper cold air to continuously fall inside the space between the wind control element 3100 and the liquid container 2100, so that the cold air moves to the right while the upper and lower cold air are continuously exchanged inside the space between the wind control element 3100 and the liquid container 2100.

[0133] If there were no steps 3111 on the wind control surface 3110, the cold wind would only blow from right to left. In this state, the interior of the cold wind would be stationary, and only the lower part of the cold wind would exchange cold energy with the ice cubes.

[0134] After adding a number of steps 3111 on the wind control surface 3110, the cold air is constantly circulating up and down, so that the cold air exchanges cold energy with the ice tray below, and the heat in the entire cold air is exchanged together.

[0135] like Figure 29 and Figure 30 The table shown is a comparison of the temperature test results of cold air at the left air outlet distance 3206 before and after the steps 3111 without the wind control surface 3110 are set and the steps 3111 with the wind control surface 3110 are added (unit: degree).

[0136] The greater the temperature difference between the air inlet spacing 3205 and the air outlet spacing 3206, the more and more sufficient the cold air and ice cubes are exchanged. Figure 29 and Figure 30 As can be seen from the table shown, when several steps 3111 of the wind control surface 3110 are set, the temperature difference between the inlet and outlet air is approximately 7.7°, while when several steps 3111 of the wind control surface 3110 are not set, the temperature difference between the inlet and outlet air is approximately 6.67°. Therefore, the temperature of the refrigerator with several steps 3111 of the wind control surface 3110 is approximately 1 degree higher than that of the refrigerator without several steps 3111 of the wind control surface 3110.

[0137] This indicates that after passing through the steps 3111 of the wind-control surface 3110, the cold air also undergoes cold exchange, thoroughly mixing the air above and below it. Throughout this process, the cold air not only mixes and exchanges cold energy internally, but also exchanges cold energy with the water in the ice tray at the bottom. Ultimately, more cold energy is absorbed by the water in the ice tray, resulting in faster freezing of the ice tray. This conclusion is consistent with the aforementioned ice tray freezing speed comparison table.

[0138] In one embodiment, the refrigerator door may further include an ice storage box 4000, which is arranged in the ice making chamber 1001, and the ice storage box 4000 is located below the ice maker 2000. The ice cubes made by the ice maker 2000 can fall from the liquid container 2100 based on the action of gravity, and then fall into the ice storage box 4000 to realize the storage and standby of the ice cubes.

[0139] The flow guide space 1004 in the ice making chamber 1001 can be connected to the space where the ice storage box 4000 is located in the ice making chamber 1001 through at least one of the first gap 3201, the second gap 3202, the outer gap 3203 and the inner gap 3204, and connected to the fluid outlet 1003.

[0140] In some embodiments of the present application, the ice maker 2000 may further include a drive mechanism configured to rotate the liquid container 2100. Thus, after the water in the ice tray 2101 of the liquid container 2100 freezes and turns into ice cubes, the drive mechanism may drive the liquid container 2100 to rotate and twist, causing the ice cubes to fall out of the ice tray 2101 of the liquid container 2100 and fall into the ice storage box 4000.

[0141] As can be seen from the above, ice-making liquid needs to absorb a large amount of cold energy to form ice cubes. This process requires concentrating the cold energy at the location of the liquid container 2100 to achieve the fastest ice production. Therefore, in one embodiment, the door body 1000 is provided with a guide duct 1100, which is connected to the fluid inlet 1002. The guide duct 1100 can be designed with a direction, channel trajectory, etc. according to needs. Therefore, the guide duct 1100 can be configured to guide the refrigeration fluid 10 above the liquid container 2100 toward the wind control device 3000, achieving a predictable flow direction of the refrigeration fluid 10.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0143] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
