Abstract
Description
Technical Field
[0001] This application relates to the field of refrigerator technology, and more particularly to a refrigerator. Background Technology
[0002] Currently, some refrigerators have a water tank and water filling mechanism inside the door. Users can control the water filling mechanism through the control panel on the refrigerator door to inject a certain amount of water into the water tank. The water in the water tank can be turned into cold water under the cooling effect of the refrigerator, which is convenient for users to take out as needed.
[0003] However, the water filling mechanism requires user operation to both start and stop water filling, and the water volume needs to be set by the user via the control panel. When there is a certain amount of water left in the kettle, the user needs to reset the water filling volume based on the remaining water level; otherwise, overfilling may occur, causing the kettle to overflow. In other words, the existing refrigerator's water filling mechanism has a low level of intelligence, and the water filling operation is cumbersome. Summary of the Invention
[0004] The refrigerator provided in this application can automatically dispense water and dispense a fixed amount of water from the kettle inside the refrigerator, demonstrating a high level of intelligence.
[0005] In a first aspect, this application provides a refrigerator, comprising:
[0006] The housing has a receiving chamber;
[0007] A door, which is rotatably mounted on the housing, is used to cover or expose the receiving chamber;
[0008] A kettle, which is detachably mounted on the door;
[0009] A water injection mechanism is provided on the door body; a position detection unit is provided on the door body, and the water injection mechanism is used to inject water into the kettle when the position detection unit detects a preset position of the kettle on the door body;
[0010] The liquid level detection mechanism includes: a connecting component disposed on the door body, the connecting component comprising:
[0011] A pressure-bearing member is movably disposed on the door body, the pressure-bearing member is used to abut against the kettle, and moves relative to the door body under the action of the kettle;
[0012] A movable component, connected to the pressure-bearing component, configured to move in a direction toward the kettle when the pressure-bearing component moves relative to the door body;
[0013] A liquid level detection unit is disposed on the movable component. The liquid level detection unit is configured to move under the drive of the movable component to abut against the kettle to detect the liquid level of the kettle. The water filling mechanism is also used to stop filling the kettle with water when the liquid level detection unit detects that the liquid level of the kettle has reached a preset liquid level.
[0014] The refrigerator of this application features a position detection unit on the door. This unit automatically detects when a user places a water bottle on the door to determine if it is in a preset position. When the position detection unit detects the water bottle is in the preset position, the water filling mechanism automatically fills the water bottle. Simultaneously, the door also has a movable pressure-bearing component connected to it. This component has a liquid level detection unit mounted on it. When the user places the water bottle in the preset position, the bottle acts on the pressure-bearing component, which in turn causes the movable component to move the liquid level detection unit toward the water bottle. When the water bottle reaches the preset position, the liquid level detection unit contacts the bottle and detects the liquid level. When the liquid level detection unit detects that the water level has reached the preset level, the water filling mechanism stops filling the water bottle. This achieves automatic and quantitative water filling of the water bottle inside the refrigerator, improving the intelligence level of the water filling mechanism.
[0015] In one possible implementation, the connection component further includes:
[0016] A pivot shaft is rotatably disposed on the door body. The pressure-bearing member and the movable member are both connected to the pivot shaft radially. The movable member is connected to the pressure-bearing member through the pivot shaft. The pivot shaft is configured to rotate relative to the door body when the kettle acts on the pressure-bearing member, so that the movable member moves toward the kettle.
[0017] Both the pressure-bearing component and the moving component are connected to the pivot shaft radially, and the pivot shaft is rotatably mounted on the door. When the kettle acts on the pressure-bearing component, the pivot shaft rotates relative to the door, causing the moving component to move towards the kettle. In other words, the connecting assembly adopts a seesaw-like form, which simplifies the structure of the connecting assembly and reduces the manufacturing cost of the refrigerator.
[0018] In one possible implementation, the pressure-bearing member and the movable member are arranged at an angle, the angle between the pressure-bearing member and the movable member being α, and α satisfies the following relationship: α≥45°, and / or α≤90°.
[0019] When α ≥ 45°, it ensures that the liquid level detection unit can be positioned appropriately within the limited dimensions of the pressure-bearing and moving parts, ensuring a high preset liquid level in the kettle and preventing insufficient water intake. Simultaneously, it avoids making the pressure-bearing and moving parts excessively large to achieve a reasonable height for the liquid level detection unit. Because when the angle between the pressure-bearing and moving parts is greater than 90°, a gap may still exist between the liquid level detection unit and the kettle when it reaches the preset position, preventing them from contacting the kettle and detecting the liquid level. Therefore, when α ≤ 90°, it ensures that when the kettle acts on the pressure-bearing part at the preset position, the moving part can contact the kettle and detect the liquid level.
[0020] In one possible implementation, the pressure-bearing component further includes:
[0021] A pivot axis, which is rotatably disposed on the door body;
[0022] A pressure plate is radially connected to the pivot axis, and the movable member is connected to the end of the pressure plate away from the pivot axis.
[0023] An elastic element has two opposing ends, one end of which is connected to the door body and the other end is connected to the pressure plate. When the kettle acts on the pressure plate, the pressure plate compresses the elastic element, and the elastic element drives the movable element to make the liquid level detection unit abut against the kettle.
[0024] A pressure plate is rotatably mounted on the door via a pivot. A movable component is connected to the end of the pressure plate away from the pivot. An elastic component is positioned between the pressure plate and the door, with one end connected to the door and the other to the pressure plate. When the kettle acts on the pressure plate, the elastic component is gradually compressed under its force. When the kettle reaches a preset position, the elastic component is compressed, ensuring that the liquid level detection unit remains in contact with the kettle, allowing the unit to detect the liquid level. When the user removes the kettle, the elastic component drives the pressure plate to reset the liquid level detection unit, ensuring that the unit is always in contact with the kettle when it is in the preset position.
[0025] In one possible implementation, the movable element is configured to bend to adjust the position of the liquid level detection unit relative to the door in the height direction of the housing.
[0026] By making the movable part flexible, the position of the liquid level detection unit relative to the door in the height direction of the housing can be changed by bending the movable part, thereby changing the position of the liquid level detection unit relative to the kettle located in a preset position, and thus changing the liquid level height detected by the liquid level detection unit. In this way, users can adjust the position of the liquid level detection unit according to actual needs to change the amount of water dispensed.
[0027] Secondly, this application also provides a refrigerator, comprising:
[0028] The housing has a receiving chamber;
[0029] A door, which is rotatably mounted on the housing, is used to cover or expose the receiving chamber;
[0030] A kettle, which is detachably mounted on the door;
[0031] A water injection mechanism is provided on the door body;
[0032] A pressure detection mechanism is provided on the door body. The water injection mechanism is used to inject water into the kettle when the kettle presses against the pressure detection mechanism. The water injection mechanism is also used to stop injecting water into the kettle when the pressure detection mechanism detects that the pressure applied by the kettle to the pressure detection mechanism has reached a preset value.
[0033] By installing a pressure detection mechanism on the refrigerator door, the water injection mechanism can automatically inject water into the kettle when the pressure detection mechanism detects that the kettle is pressed against it. When the pressure detection mechanism detects that the pressure applied by the kettle to the pressure detection mechanism has reached a preset value, the water injection mechanism can stop injecting water into the kettle. In this way, the water injection mechanism can automatically and quantitatively inject water into the kettle inside the refrigerator, improving the intelligence level of the water injection mechanism on the refrigerator.
[0034] In one possible implementation, the pressure detection mechanism includes: a position detection unit disposed on the door body, wherein the water injection mechanism is used to inject water into the kettle when the pressure detection mechanism detects that the kettle is located at a preset position on the door body; and a pressure detection unit disposed on the door body, wherein the water injection mechanism is used to stop injecting water into the kettle when the pressure detection unit detects that the pressure applied to the pressure detection unit by the kettle reaches a preset value.
[0035] By independently configuring the position detection unit and the pressure detection unit, the detection accuracy and reliability of the units can be improved, which is beneficial to enhancing the expandability and compatibility of the refrigerator. Furthermore, the modular design facilitates rapid location and maintenance of refrigerator-related functional faults.
[0036] In one possible implementation, at least a portion of the door's wall surface is configured as an inclined surface that is tilted relative to the height direction of the box, and the pressure detection mechanism is disposed on the inclined surface; the door is provided with a suspension structure for suspending the kettle, and when the kettle is suspended on the suspension structure, the kettle presses against the pressure detection mechanism.
[0037] A suspension structure for hanging a kettle is installed on the door. A portion of the door's wall is designed as an inclined surface relative to the height of the cabinet, and a pressure detection mechanism is positioned on this inclined surface. When the kettle is suspended on the suspension structure, it presses against the pressure detection mechanism. The kettle's own weight, or the component of the weight of the kettle and the water inside it in the direction perpendicular to the inclined surface, applies pressure to the mechanism. Thus, the pressure detection mechanism determines whether the kettle is in place and whether the water intake has reached the preset amount by detecting the component of the weight of the kettle and the water inside it in the direction perpendicular to the inclined surface. Compared to directly detecting gravity, detecting the component of gravity in a specific direction allows for the use of a smaller-range detection unit with higher accuracy and sensitivity, improving the accuracy of the detection results.
[0038] In one possible implementation, the tilt angle of the inclined surface relative to the height direction of the box is β, and β satisfies the relationship: β≥5°, and / or β≤15°.
[0039] When the tilt angle of the inclined surface relative to the height direction of the box is β≥5°, it ensures that the pressure applied by the kettle to the inclined surface is large enough to meet the testing requirements of the pressure testing mechanism. When the tilt angle of the inclined surface relative to the height direction of the box is β≤15°, it ensures that the position of the inclined surface relative to other walls of the door is appropriate. For example, if the inclined surface protrudes from other walls of the door, it can prevent the door from being too thick in the area of the inclined surface. If the inclined surface is a wall surface with a groove set on the door, it can prevent the box from being too thin in the area of the inclined surface.
[0040] Thirdly, this application provides a refrigerator, comprising:
[0041] The housing has a receiving chamber;
[0042] A door, which is rotatably mounted on the housing, is used to cover or expose the receiving chamber;
[0043] A kettle, which is detachably mounted on the door;
[0044] A water injection mechanism is provided on the door body;
[0045] A position detection unit is disposed on the door body, and the water injection mechanism is used to inject water into the water bottle when the position detection unit detects a preset position of the water bottle on the door body;
[0046] A liquid level detection unit is disposed on the door body. The liquid level detection unit is used to detect the liquid level height of the kettle. The water injection mechanism is also used to stop injecting water into the kettle when the liquid level detection unit detects that the liquid level of the kettle has reached a preset liquid level.
[0047] An elastic element is disposed on the door body and configured such that when the kettle is in the preset position, the elastic element drives the kettle to abut against the liquid level detection unit.
[0048] By installing a position detection unit on the door, the system automatically detects when the user places the kettle on the door to determine if it is in the preset position. When the position detection unit detects that the kettle is in the preset position, the water filling mechanism starts filling the kettle, achieving automatic water filling. Furthermore, the door also has a corresponding liquid level detection unit and an elastic element. When the user places the kettle in the preset position, the elastic element causes the kettle to press against the liquid level detection unit, allowing the unit to detect the liquid level. When the liquid level detection unit detects that the liquid level has reached the preset level, the water filling mechanism stops filling the kettle. This enables automatic and metered water filling of the kettle inside the refrigerator, improving the intelligence level of the refrigerator's water filling mechanism.
[0049] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0050] The refrigerator of this application, by incorporating a position detection unit on the door, automatically detects when a user places a water bottle on the door to determine if it is in a preset position. When the position detection unit detects the water bottle in the preset position, the water filling mechanism automatically fills the water bottle. Simultaneously, the door also features a movable pressure-bearing component connected to a moving component, which houses a liquid level detection unit. As the user places the water bottle in the preset position, the bottle acts on the pressure-bearing component, causing the moving component to move the liquid level detection unit towards the water bottle. When the water bottle reaches the preset position, the liquid level detection unit contacts the bottle and detects the liquid level. When the liquid level detection unit detects that the water level has reached the preset level, the water filling mechanism stops filling the water bottle. This achieves automatic and quantitative water filling of the water bottle inside the refrigerator, improving the intelligence level of the water filling mechanism. Attached Figure Description

[0073] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0074] In this application, the terms "upper," "lower," "bottom," "inner," "outer," and "middle," etc., indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.
[0075] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.
[0076] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable link, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
[0077] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.
[0078] In this design, the water dispensing operation of the refrigerator's water jug is manually performed by the user. Specifically, the user sets the water dispensing volume on the refrigerator's control panel and starts the water dispensing mechanism. After dispensing water to the jug according to the set volume, the mechanism automatically stops dispensing. If a certain amount of water remains in the jug, the user needs to determine the amount of water needed based on the jug's capacity, then reset the dispensing volume, and the mechanism will then dispense water according to the reset amount. In other words, the water dispensing mechanism in this design has a low level of intelligence, requiring users to perform cumbersome water dispensing operations, and the water dispensing volume also needs to be repeatedly adjusted by the user based on actual conditions, resulting in a poor user experience.
[0079] To solve the aforementioned technical problems, the inventors attempted to install a spring on the refrigerator door, and then install a liquid level sensor on the spring. When the kettle is placed on the door, the kettle abuts against the liquid level sensor and compresses the spring. The spring keeps the liquid level sensor and the kettle in contact to detect the liquid level in the kettle. When the kettle reaches the preset liquid level, the water filling mechanism stops filling the kettle, thus achieving a quantitative water dispensing.
[0080] While using a level sensor to detect the water level in the kettle and limit the amount of water dispensed by the filling mechanism can achieve quantitative water dispensing, the design in this case requires the level sensor to protrude from the door surface to ensure contact with the kettle when it is in the preset position. This results in poor door surface flatness and a large door size. Furthermore, the fixed detection level of the level sensor in this design prevents adjustment of the dispensing volume based on actual conditions. Additionally, when the user closes the refrigerator door, the kettle may displace due to inertia, potentially exceeding the spring's natural length, thus preventing the level sensor from effectively detecting the water level.
[0081] It is evident that the quantitative water intake system still has several shortcomings, such as low surface flatness of the gate and low flexibility in quantitative water intake.
[0082] To address the aforementioned technical problems, this application provides a refrigerator that incorporates a detection mechanism on the door. When the detection mechanism detects that the water jug is in a preset position, the water injection mechanism injects water into the jug. When the detection mechanism detects that the water volume has reached the preset volume, the water injection mechanism stops injecting water. This enables automatic and quantitative water injection into the refrigerator's water jug, improving the intelligence level of the water injection mechanism.
[0083] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.
[0084] Please see Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of a refrigerator according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shown is a three-dimensional structural diagram of the refrigerator's body. Figure 3 yes Figure 2 The diagram shows the three-dimensional structure of the door. Figure 4 yes Figure 3 The diagram shown is an exploded view of the door and kettle. Figure 5 This is an assembly diagram of the kettle and the liquid level detection mechanism.
[0085] The refrigerator 1000 in this embodiment includes a cabinet 1100, a door 1200, a kettle 1300, a water filling mechanism 1400, a position detection unit 1500, and a liquid level detection mechanism 1600.
[0086] The cabinet 1100 has a receiving chamber 1110, which can be divided into different functional spaces such as a freezer compartment and a fresh food compartment. Users can use these functional spaces to store fruits, vegetables, fresh food, or other items according to their actual needs.
[0087] The door 1200 is rotatably mounted on the housing 1100. By rotating the door 1200, the aforementioned receiving chamber 1110 can be covered or exposed.
[0088] The kettle 1300 is detachably mounted on the door 1200. Specifically, the kettle 1300 is detachably mounted on the inside of the door 1200. That is, when the kettle 1300 is mounted on the door 1200 and the door 1200 covers the receiving chamber 1110, the kettle 1300 is located in the receiving chamber 1110.
[0089] Water injection mechanism 1400 is installed on door 1200 and is used to supply water to kettle 1300.
[0090] A position detection unit 1500 is disposed on the door 1200. The position detection unit 1500 is used to detect whether the kettle 1300 is located in a preset position on the door 1200. When the position detection unit 1500 detects that the kettle 1300 is in the preset position, the water filling mechanism 1400 fills the kettle 1300 with water.
[0091] The liquid level detection mechanism 1600 includes a connecting component 1610 and a liquid level detection unit 1620, both of which are mounted on the door body 1200.
[0092] The connecting assembly 1610 includes a pressure-bearing member 1611 and a movable member 1612. The pressure-bearing member 1611 is movably disposed on the door body 1200, serves as abutment for the kettle 1300, and moves relative to the door body 1200 under the action of the kettle 1300. The movable member 1612 is connected to the pressure-bearing member 1611 and is configured to move in a direction toward the kettle 1300 when the pressure-bearing member 1611 moves relative to the door body 1200. Thus, when the kettle 1300 reaches a preset position, the liquid level detection unit 1620 can abut against the kettle 1300 to detect the liquid level. When the liquid level detection unit 1620 detects that the liquid level in the kettle 1300 has reached the preset level, the water filling mechanism 1400 stops filling the kettle 1300 with water.
[0093] As can be seen, when the user places the kettle 1300 in the preset position on the door 1200, the position detection unit 1500 can detect that the kettle 1300 is in place. At this time, the water filling mechanism 1400 fills the kettle 1300 with water, realizing automatic water filling. If the position detection unit 1500 does not detect the kettle 1300 in the preset position, the water filling mechanism 1400 will not dispense water, preventing water leakage that could lead to waste or soaking other items inside the refrigerator 1000. When the liquid level in the kettle 1300 reaches the preset level, the liquid level detection unit 1620 detects the level, and the water filling mechanism 1400 stops filling, realizing quantitative water filling.
[0094] It is understood that the above-mentioned preset liquid level can be a pre-set liquid level, such as the maximum water level of the kettle, or it can be lower than the maximum water level of the kettle, such as 1.5L, 1L or 500ML, etc., which can be set according to the user's needs.
[0095] It is understood that the preset position can refer to any position on the refrigerator door. For example, in some embodiments, the door 1200 is provided with a placement platform 1210, and when the kettle 1300 is in the preset position, the kettle 1300 is located on the placement platform 1210. In this case, the position detection unit 1500 can be located on the placement platform 1210. Alternatively, a hook can be provided on the door 1200, and when the kettle 1300 is in the preset position, the kettle 1300 can be hung on the hook.
[0096] In some embodiments, the placement table 1210 may be provided with a positioning groove 1211. When the kettle 1300 is placed in a preset position, the kettle 1300 is partially located in the positioning groove 1211. The side wall of the positioning groove 1211 can restrict the position of the kettle 1300 and prevent the kettle 1300 from falling off the door.
[0097] In some embodiments, such as Figure 4 As shown, when the kettle 1300 is placed in the preset position, a certain amount of water may remain inside. If the liquid level detection unit 1620 cannot detect water at the preset liquid level, the water filling mechanism 1400 can fill the kettle 1300 with water to achieve automatic water replenishment. In some scenarios, after removing the kettle 1300, the user may place it back in the preset position without using any water. In this case, the liquid level detection unit 1620 can detect water at the preset liquid level, and the water filling mechanism 1400 will not fill the kettle 1300 with water, thus avoiding overfilling and causing water to overflow from the kettle 1300.
[0098] Optionally, the position detection unit 1500 can be an optical sensor, a pressure sensor, a Hall sensor, or other components with position detection function. This embodiment uses an optical sensor as an example for illustration, but is not limited thereto.
[0099] The liquid level detection unit 1620 can be a non-contact liquid level sensor, such as a capacitive liquid level sensor, an ultrasonic liquid level sensor, a separate photoelectric liquid level sensor, a pipeline liquid level sensor, or a Hall sensor. This embodiment uses a capacitive liquid level sensor as an example for explanation, but it is not limited thereto.
[0100] See also Figures 5 to 7 , Figure 6 yes Figure 4 Enlarged diagram of region A in the middle. Figure 7 This is a three-dimensional structural diagram of a damping element disposed on the first pivot shaft according to an embodiment of this application.
[0101] In some embodiments, the connecting assembly 1610 further includes a first pivot shaft 1613, which is rotatably mounted on the door body 1200. Both the pressure-bearing member 1611 and the movable member 1612 are connected to the first pivot shaft 1613 radially; that is, the movable member 1612 is connected to the pressure-bearing member 1611 via the first pivot shaft 1613. When the user places the kettle 1300 in a preset position, the kettle 1300 acts on the pressure-bearing member 1611, causing the first pivot shaft 1613 to rotate relative to the door body 1200. The first pivot shaft 1613 drives the movable member 1612 to rotate relative to the door body 1200 in a direction closer to the door body 1200, causing the liquid level detection unit 1620 to move synchronously towards the kettle 1300. When the kettle 1300 reaches the preset position, the liquid level detection unit 1620 comes into contact with the kettle 1300, thereby detecting whether the liquid level in the kettle 1300 has reached the preset liquid level.
[0102] It is understandable that two opposing pivot holes 1212 or pivot slots (not shown) can be provided on the door body 1200, and the two ends of the first pivot shaft 1613 extend into the two pivot holes 1212 or pivot slots respectively.
[0103] In some embodiments, damping elements 1613a may be provided on the outer periphery of both ends of the first pivot shaft 1613, and / or damping elements (not shown) may be provided in the two pivot holes or pivot grooves. Thus, when the first pivot shaft 1613 rotates relative to the door body 1200, the damping elements 1613a can provide a certain amount of damping, reducing or eliminating abnormal noise generated by the rotation of the first pivot shaft 1613 relative to the door body 1200, and improving the stability of the first pivot shaft 1613 during rotation. Optionally, the damping elements 1613a may be made of elastic materials such as rubber or silicone.
[0104] It is understood that the pressure-bearing component 1611, the movable component 1612 and the first pivot shaft 1613 can be independent components or integrally formed structures. This embodiment is illustrated by taking the pressure-bearing component 1611, the movable component 1612 and the first pivot shaft 1613 as an integral structure, but it is not limited thereto.
[0105] Please see also Figure 8 , Figure 8 yes Figure 7 The diagram shows a side view of the liquid level detection mechanism.
[0106] In some embodiments, the pressure-bearing member 1611, the movable member 1612, and the first pivot shaft 1613 form a seesaw-like structure, in which case the pressure-bearing member 1611 and the movable member 1612 are arranged at an angle. That is, the connection assembly 1610 adopts a seesaw form, which can simplify the structure of the connection assembly 1610 and reduce the manufacturing cost of the refrigerator 1000.
[0107] In some embodiments, the axial direction of the first pivot shaft 1613 can be set to be parallel to the height direction H of the housing 1100. In this case, when the kettle 1300 is placed in the preset position, the side wall of the kettle 1300 acts on the pressure bearing member 1611, and the liquid level detection unit 1620 abuts against the side wall of the kettle 1300.
[0108] In some other embodiments, the axial direction of the first pivot shaft 1613 can be set to be perpendicular to the height direction H of the housing 1100, that is, the axial direction of the first pivot shaft 1613 is horizontal. In this case, when the kettle 1300 is placed in the preset position, the bottom wall of the kettle 1300 presses against the pressure-bearing member 1611, and the liquid level detection unit 1620 abuts against the side wall of the kettle 1300. This embodiment uses the example of the first pivot shaft 1613 being perpendicular to the height direction H of the housing 1100 for illustration, but it is not limited to this.
[0109] Understandably, the first pivot shaft 1613 is rotatably mounted on the placement platform 1210. When the kettle 1300 is in a preset position, the kettle 1300 presses the pressure-bearing member 1611 onto the placement platform 1210. When the placement platform 1210 is provided with a positioning groove 1211, the pressure-bearing member 1611 is located in the positioning groove 1211. The positioning groove 1211 can position the kettle 1300, enabling the kettle 1300 to effectively abut against the liquid level detection unit 1620, thereby allowing the liquid level detection unit 1620 to normally detect the liquid level of the kettle 1300.
[0110] In some embodiments, the pressure-bearing member 1611 can be configured as a plate, namely a first pressure plate. When the kettle 1300 is in a preset position, the first pressure plate supports the kettle 1300 and causes the movable member 1612 to drive the liquid level detection unit 1620 to abut against the kettle 1300.
[0111] In some embodiments, the movable member 1612 can also be configured as a plate, and the extending directions of the movable member 1612 and the pressure-bearing member 1611 can form an angle. For example, the pressure-bearing member 1611 can extend horizontally, while the movable member 1612 can extend vertically along the height direction H of the refrigerator 1000. In this way, when the kettle 1300 is placed on the placement platform 1210, the pressure-bearing member 1611 can contact the bottom surface of the kettle 1300, that is, the pressure-bearing member 1611 is disposed on the bottom surface of the placement platform 1210, while the movable member 1612 can contact the side surface of the kettle 1300 along the height direction H, thereby enabling the liquid level detection unit 1620 disposed on the movable member 1612 to detect the liquid level in the kettle 1300 along the height direction H of the kettle 1300.
[0112] In some embodiments, the included angle between the pressure-bearing member 1611 and the movable member 1612 is α, and α satisfies the relationship: α ≥ 45°. It is understood that if the included angle α is too small, when the pressure-bearing member 1611 carries the kettle 1300, if the liquid level detection unit 1620 on the movable member 1612 is to detect a higher liquid level, the dimensions of the pressure-bearing member 1611 and the movable member 1612 need to be increased. This would result in an excessively large connecting assembly 1610, leading to an excessively large door thickness 1200. Ensuring α ≥ 45° ensures that, given the limited dimensions of the pressure-bearing member 1611 and the movable member 1612, the liquid level detection unit 1620 can be positioned appropriately, ensuring a higher preset liquid level in the kettle 1300 and preventing insufficient water intake. Simultaneously, it also avoids the situation where the dimensions of the pressure-bearing member 1611 and the movable member 1612 become excessive to achieve a reasonable height for the liquid level detection unit 1620.
[0113] In some embodiments, the included angle α also satisfies the relationship: α≤90°. It is understood that when the included angle α between the pressure-bearing member 1611 and the movable member 1612 is greater than 90°, when the kettle 1300 reaches the preset position, there may still be a gap between the liquid level detection unit 1620 and the kettle 1300, preventing it from contacting the kettle 1300 and detecting its liquid level. Therefore, by ensuring α≤90°, it can be ensured that when the kettle 1300 acts on the pressure-bearing member 1611 at the preset position, the movable member 1612 can contact the kettle 1300 and detect its liquid level.
[0114] For example, when the kettle 1300 is not yet placed on the placement platform 1210, it is not in contact with the pressure-bearing member 1611. Both the pressure-bearing member 1611 and the movable member 1612 are relatively stationary, and the angle between them can be slightly less than 90°. When the kettle 1300 is placed on the placement platform 1210, it comes into contact with the pressure-bearing member 1611, pressing it against the pressure-bearing member 1611 and causing it to rotate relative to the door 1200. At this time, under the action of the pressure-bearing member 1611 and the first pivot shaft 1613, the movable member 1612 moves towards the kettle 1300 to abut against it. The angle between the movable member 1612 and the pressure-bearing member 1611 is approximately 90°.
[0115] In one example, the kettle 1300 is configured as a columnar structure, with an included angle α of 90° between the pressure-bearing member 1611 and the movable member 1612. When the kettle 1300 is placed on the pressure-bearing member 1611 and is in a preset position, the liquid level detection unit 1620 on the movable member 1612 just abuts against the side wall of the kettle 1300.
[0116] Understandably, when the user opens or closes the door 1200, the door 1200 rotates around its axis, and at the same time, the kettle 1300 also rotates around its axis. The movement path of the kettle 1300 can be considered as an arc curve. When the user closes the door 1200, the kettle 1300 may be affected by inertia, resulting in a displacement towards the interior of the receiving chamber 1110, and the kettle 1300 may move away from the liquid level detection unit 1620. Therefore, the liquid level detection unit 1620 can be arranged on opposite sides of the kettle 1300 along a direction perpendicular to the movement path of the kettle 1300 (for example, on both sides of the kettle in the width direction). In this way, even if the kettle 1300 moves, the liquid level detection unit 1620 can remain in contact with the side of the kettle 1300.
[0117] Please see also Figures 9 to 11 , Figure 9 This is a three-dimensional structural diagram of the liquid level detection mechanism with a sliding member according to an embodiment of this application. Figure 10This is a three-dimensional structural diagram of the liquid level detection mechanism according to an embodiment of this application, which includes a slide rail and a sliding component. Figure 11 This is a three-dimensional structural diagram of the liquid level detection mechanism according to an embodiment of this application, where the movable component is configured as a telescopic structure.
[0118] In some embodiments, the liquid level detection unit 1620 is movably disposed on the movable member 1612 along the height direction H. Thus, by adjusting the position of the liquid level detection unit 1620, the height of the preset liquid level can be changed, allowing the user to adjust the preset liquid level according to actual needs and change the amount of water dispensed.
[0119] In some embodiments, the movable member 1612 is rod-shaped, and the liquid level detection unit 1620 can be connected to the movable member 1612 via a sliding member 1612a that can slide on the movable member 1612, such as a sliding sleeve. By moving the sliding member 1612a, the position of the liquid level detection unit 1620 can be adjusted.
[0120] In some embodiments, the movable member 1612 is plate-shaped or column-shaped. The movable member 1612 may be provided with a slide rail 1612b extending along the height direction H. The liquid level detection unit 1620 can be connected to the movable member 1612 via a slider or the like that can move on the slide rail 1612b. By moving the position of the slider 1612a on the slide rail 1612b, the position of the liquid level detection unit 1620 can be changed.
[0121] Optionally, the slide rail 1612b may be composed of a protrusion extending along the height direction H or a groove extending along the height direction H, and the slider 1612a may have a structure that mates with the protrusion or the groove.
[0122] When the slide rail 1612b is formed by a slide groove, both sidewalls of the slide groove along the height direction H can be provided with multiple protrusions along the height direction H. For example, both sidewalls of the slide groove can form a rack-like structure. The space between any two adjacent protrusions on the same sidewall can be used to accommodate the sliding member 1612a, while two opposing protrusions on the two sidewalls can limit the sliding member 1612a to prevent the sliding member 1612a and the liquid level detection unit 1620 from automatically moving downwards. Optionally, the protrusions can be triangular, square, semi-circular, etc., and this embodiment does not specifically limit them.
[0123] In some embodiments, the movable element 1612 can be configured as a telescopic structure that is retractable along the height direction H of the housing 1100, such as a telescopic rod. Thus, by extending or retracting the movable element 1612, the position of the liquid level detection unit 1620 relative to the kettle 1300 in the height direction H can be adjusted, thereby changing the height of the preset liquid level. Users can adjust the preset liquid level according to actual needs to change the amount of water dispensed.
[0124] Understandably, when the liquid level detection unit 1620 is movable along the height direction H, the liquid level detection unit 1620 can also be set on opposite sides of the water bottle 1300 along a movement path direction perpendicular to the water bottle 1300.
[0125] In some embodiments, the door 1200 may also be provided with a receiving groove (not shown). When the user removes the kettle 1300 from the preset position, the movable member 1612 and the liquid level detection unit 1620 are received in the receiving groove, which can make the inner surface of the door 1200 cleaner. Specifically, the receiving groove is provided corresponding to the movable member 1612 and the liquid level detection unit 1620. When the kettle 1300 leaves the preset position, the movable member 1612 is affected by the gravity of the liquid level detection unit 1620. The center of gravity of the structure formed by the connection between the movable member 1612 and the liquid level detection unit 1620 is relatively high. After the door 1200 is opened, the movable member 1612 continues to move due to the weight and inertia of the liquid level detection unit 1620, causing the movable member 1612 to rotate towards the direction closer to the door 1200. This causes a portion of the movable member 1612 near the liquid level detection unit 1620 to fall into the receiving groove together with the liquid level detection unit 1620.
[0126] Please see also Figure 12 and Figure 13 , Figure 12 This is an assembly diagram of a kettle and another liquid level detection mechanism. Figure 13 yes Figure 12 The diagram shows a top view of the kettle and the liquid level detection mechanism.
[0127] In some embodiments, the pressure-bearing member 1611 includes a second pivot shaft 1611a and a second pressure plate 1611b. The second pivot shaft 1611a is rotatably mounted on the door body 1200, and the second pressure plate 1611b is radially connected to the second pivot shaft 1611a, allowing the second pressure plate 1611b to rotate relative to the door body 1200. The movable member 1612 is connected to the end of the second pressure plate 1611b away from the second pivot shaft 1611a.
[0128] When the user places the kettle 1300 into the preset position, the kettle 1300 presses against the second pressure plate 1611b and simultaneously abuts against the liquid level detection unit 1620 disposed on the movable part 1612, so that the liquid level detection unit 1620 detects the liquid level of the kettle 1300.
[0129] It should be noted that the axial direction of the second pivot axis 1611a can be set to be parallel to the height direction H or perpendicular to the height direction H. The following explanation uses the example of the axial direction of the second pivot axis 1611a being parallel to the height direction H, but it is not limited to this.
[0130] See you again Figure 12 and Figure 13 In some embodiments, the pressure-bearing member 1611 further includes a first elastic member 1611c, which has two opposing ends. One end of the first elastic member 1611c is connected to the door body 1200, and the other end is connected to the second pressure plate 1611b. When the user places the kettle 1300 in the preset position, the kettle 1300 presses against the second pressure plate 1611b, causing the second pressure plate 1611b to compress the first elastic member 1611c. When the kettle 1300 is in the preset position, the kettle 1300, through the second pressure plate 1611b, keeps the first elastic member 1611c in a compressed state. Under its own elasticity, the first elastic member 1611c causes the liquid level detection unit 1620 on the movable member 1612 to tightly abut against the kettle 1300, so that the liquid level detection unit 1620 can detect the liquid level in the kettle 1300. When the user removes the kettle 1300 from the preset position, the first elastic element 1611c can drive the second pressure plate 1611b to reset the movable element 1612 and the liquid level detection unit 1620.
[0131] In some embodiments, the first elastic element 1611c may include, but is not limited to, a spring, a sheet, a rubber element, a silicone element, etc.
[0132] In some embodiments, the movable member 1612 is configured as a bendable component. By bending the movable member 1612, the position of the liquid level detection unit 1620 relative to the door 1200 in the height direction H can be adjusted, thereby changing the position of the liquid level detection unit 1620 relative to the kettle 1300 which is in a preset position. Thus, by bending the movable member 1612, the height of the preset liquid level detected by the liquid level detection unit 1620 can be adjusted, allowing the user to adjust the amount of water dispensed each time according to actual needs.
[0133] In some embodiments, the movable member 1612 is configured as a multi-jointed rod-like structure, such as a universal joint, allowing it to bend / bend / deform in its radial direction. One end of the movable member 1612 is connected to the second pressure plate 1611b, and the other end is provided with a liquid level detection unit 1620. In this way, the liquid level detection unit 1620 can be adjusted in position by bending / bending the movable member 1612.
[0134] When the movable part 1612 is a rod-shaped structure, it can be configured to be non-extendable along its axial direction. This prevents the liquid level detection unit 1620 from failing to engage with the kettle 1300 due to the axial contraction of the movable part 1612 when the user places the kettle 1300 in the preset position.
[0135] In some embodiments, a limiting member (not shown) may be provided on the door 1200 to restrict the bent movable member 1612, preventing the movable member 1612 from being bent and deformed due to unexpected influences, which would prevent the liquid level detection unit 1620 from contacting the kettle 1300.
[0136] Optionally, the limiting element can be a bent pipe or a curved extending limiting groove. When the limiting element is a bent pipe, the movable part 1612 can be passed through the bent pipe first, and the movable part 1612 bends under the action of the bent pipe and is fixed by the restriction of the inner wall of the bent pipe. When the limiting element is a limiting groove, the movable part 1612 can be bent according to the extension path of the limiting groove first, and then the movable part 1612 can be placed in the limiting groove, and the inner wall of the limiting groove can be used for limiting.
[0137] It is understandable that when the movable part 1612 is a bendable component, the liquid level detection unit 1620 can also be set on opposite sides of the water bottle 1300 along a direction perpendicular to the moving path of the water bottle 1300.
[0138] Please see also Figure 14 and Figure 15 , Figure 14 This is an assembly diagram of a kettle and another type of liquid level detection mechanism. Figure 15 yes Figure 13 The diagram shows a top view of the kettle and the liquid level detection mechanism.
[0139] In some embodiments, the liquid level detection mechanism 1600 does not require a pressure-bearing member 1611 and a moving member 1612. Specifically, the liquid level detection unit 1620 can be disposed on the door 1200, and a second elastic member 1630 opposite to the liquid level detection unit 1620 can be disposed on the door 1200. When the kettle 1300 is placed in a preset position, the second elastic member 1630 drives the kettle 1300 to abut against the liquid level detection unit 1620, so that the liquid level detection unit 1620 can detect the liquid level of the kettle 1300.
[0140] In some embodiments, the second elastic element 1630 may be a spring, one end of which is connected to the door body 1200 and the other end extends toward the liquid level detection unit 1620. When the kettle 1300 is placed in a preset position, the spring is compressed by the kettle 1300. The elasticity of the spring causes the kettle 1300 to press tightly against the liquid level detection unit 1620, enabling the liquid level detection unit 1620 to detect the liquid level of the kettle 1300.
[0141] It is understandable that when the liquid level detection unit 1620 is installed on the door 1200, the liquid level detection unit 1620 can also be set to be movable relative to the door in the height direction H, thereby adjusting the height of the preset liquid level detected by the liquid level detection unit 1620.
[0142] See you again Figure 14 and Figure 15 In some embodiments, a third pivot shaft 1631 and a third pressure plate 1632 may also be provided with reference to the second pivot shaft 1611a and the second pressure plate 1611b described above. The third pivot shaft 1631 is rotatably disposed on the door body 1200, and the third pressure plate 1632 is radially connected to the third pivot shaft 1631. One end of the second elastic member 1630 is connected to the door body 1200, and the other end is connected to the end of the third pressure plate 1632 away from the third pivot shaft 1631. When the user places the kettle 1300 in the preset position, the kettle 1300 presses against the third pressure plate 1632, causing the third pressure plate 1632 to compress the second elastic member 1630. Under its own elastic force, the second elastic member 1630 drives the kettle 1300 to abut against the liquid level detection unit 1620.
[0143] Please see also Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the assembly of the second elastic element with the kettle when the second elastic element is a straight plate. Figure 17 This is a schematic diagram of the assembly of the second elastic element with the kettle when the second elastic element is Ω-shaped.
[0144] In some embodiments, the second elastic element 1630 may also be a metal spring. For example, the metal spring can be configured as a straight plate, with one end connected to the door 1200 and the other end serving as a free end for abutting against the kettle 1300 when it is in a preset position. Alternatively, the metal spring can be configured as an Ω shape, with both ends connected to the door 1200 and the middle portion curved and arched away from the door 1200, so that the elastic deformation of the metal spring provides elastic force when the kettle 1300 abuts against the metal spring. Alternatively, the metal spring can also be configured as an arc shape or a partial Ω shape.
[0145] It is understandable that, in the case where the liquid level detection unit 1620 and the second elastic element 1630 are separately arranged, the liquid level detection unit 1620 and the second elastic element 1630 are respectively arranged on opposite sides of the kettle 1300 along a direction perpendicular to the moving path of the kettle 1300.
[0146] See also Figures 18 to 20 , Figure 18 This is a schematic diagram of the inner side of the refrigerator door according to an embodiment of this application. Figure 19 yes Figure 18 A cross-sectional view along line A-A'. Figure 20 yes Figure 19 Enlarged schematic diagram of region B in the middle.
[0147] In some embodiments, the refrigerator 1000 can automatically and quantitatively fill the water injection mechanism 1400 through the detection function of the pressure detection mechanism 1640. Specifically, the pressure detection mechanism 1640 is disposed on the door 1200. When the kettle 1300 abuts against the pressure detection mechanism 1640, the pressure detection mechanism 1640 detects the pressure applied by the kettle 1300 to the pressure detection mechanism 1640. At this time, the water injection mechanism 1400 fills the kettle 1300 with water. When the pressure detection mechanism 1640 detects that the pressure applied by the kettle 1300 to the pressure detection mechanism 1640 reaches a preset value, the water injection mechanism 1400 stops filling the water.
[0148] Understandably, when the user places the kettle 1300 in the preset position, the kettle 1300 presses against the pressure detection mechanism 1640. The pressure detection mechanism 1640 detects that the kettle 1300 has reached the preset position, and then the water filling mechanism 1400 fills the kettle 1300 with water, thus achieving automatic water filling. When the total weight of the kettle 1300 and the water reaches the preset total weight, the pressure detected by the pressure detection mechanism 1640 is the preset pressure value, and then the water filling mechanism 1400 stops filling the kettle 1300 with water, thus achieving metered water filling.
[0149] In some embodiments, the pressure detection mechanism 1640 may include the aforementioned position detection unit 1500, which detects whether the kettle 1300 has reached a preset position. This prevents the water filling mechanism 1400 from filling water when the kettle 1300 has not reached the preset position.
[0150] In some embodiments, the position detection unit 1500 can be configured as a pressure sensor. Thus, when the kettle 1300 is in a preset position, pressure is applied to the pressure detection mechanism 1640. If there is no water inside the kettle 1300, or the water level inside the kettle 1300 is less than a preset amount (i.e., the weight of the kettle 1300 itself, or the total weight of the kettle 1300 and the water, does not reach a preset total weight), the water filling mechanism 1400 can fill the kettle 1300 with water.
[0151] In some embodiments, the pressure detection mechanism 1640 includes a pressure detection unit 1641, which is disposed on the door 1200. When the amount of water injected into the kettle 1300 by the water injection mechanism 1400 reaches the preset amount, the pressure detection unit 1641 detects that the total weight of the kettle 1300 and the water reaches the preset value, and then the water injection mechanism 1400 stops injecting water into the kettle 1300.
[0152] By independently configuring the position detection unit 1500 and the pressure detection unit 1641, the detection accuracy and reliability of the detection units can be improved, which is beneficial to enhancing the expandability and compatibility of the refrigerator 1000. Furthermore, the modular design facilitates the rapid location and maintenance of related functional faults in the refrigerator 1000.
[0153] In some embodiments, automatic water dispensing and quantitative water dispensing can be achieved using only the pressure detection unit 1641. Specifically, a first pressure value is set and stored. When the user places the kettle 1300 in a preset position, if there is no water inside the kettle 1300 or some water remains, the water filling mechanism 1400 will fill the kettle 1300 when the weight of the kettle 1300 itself, or the total weight of the kettle 1300 and the water, is less than the first pressure value. When the total weight of the kettle 1300 and the water is greater than or equal to the first pressure value, the water filling mechanism 1400 will stop filling the kettle 1300. In this way, automatic water dispensing and quantitative water dispensing can be achieved using only a pressure sensor, which simplifies the configuration and circuit design of the refrigerator 1000.
[0154] In some embodiments, a second pressure value can be set and stored, which is lower than the first pressure value. When the pressure detection unit 1641 detects that the pressure applied by the kettle 1300 to the pressure detection unit 1641 reaches the second pressure value, the water filling mechanism 1400 fills the kettle with water. It is understood that if the kettle 1300 is not accurately positioned, the water filling mechanism 1400 may not be able to accurately fill the kettle 1300, resulting in water overflow and waste. Simultaneously, when the kettle 1300 is not properly positioned, the pressure exerted by the kettle 1300 on the pressure detection unit 1641 may be relatively low. Thus, when the pressure exerted by the kettle 1300 on the pressure detection unit 1641 reaches the second pressure value, the water filling mechanism 1400 can be prevented from filling water when the kettle 1300 is not accurately positioned.
[0155] Please see also Figure 21 and Figure 22 , Figure 21 This is a schematic diagram of the assembly of the inclined surface of the door and the kettle in an embodiment of this application. Figure 22 yes Figure 21 The diagram shows the inclined surface separated from the kettle.
[0156] In some embodiments, the door 1200 is at least partially avoided being configured as an inclined surface 1220 tilted relative to the height direction H of the housing 1100, and the pressure detection unit 1641 is disposed on the inclined surface 1220. A suspension structure 1230 may be provided on the door 1200 for suspending the kettle 1300. When the kettle 1300 is suspended on the suspension structure 1230, the kettle 1300 presses against the pressure detection unit 1641. With this configuration, the pressure detection unit 1641 determines whether the kettle 1300 is in position and whether the water intake has reached a preset amount by detecting the weight of the kettle 1300 itself, or the component of the weight of the kettle 1300 and the water inside the kettle in a direction perpendicular to the inclined surface 1220. Compared to directly detecting gravity, detecting the component of gravity in a specific direction allows for the use of a smaller-range detection unit with higher accuracy and sensitivity, improving the accuracy of the detection results.
[0157] It is understandable that when the position detection unit 1500 and the pressure detection unit 1641 are set separately, the position detection unit 1500 can be set on the inclined surface 1220 or at other positions on the door 1200, as long as the position detection unit 1500 can detect whether the kettle 1300 is in the preset position.
[0158] Optionally, the inclined surface 1220 may be formed directly on the door body 1200, or it may be an inclined surface formed by a protruding structure protruding from the surface of the door body 1200, or it may be the bottom wall of a groove provided on the door body 1200. This application does not specifically limit this.
[0159] In some embodiments, the tilt angle of the inclined surface 1220 relative to the height direction H is β, and β satisfies the relationship: β≥5°. When the tilt angle of the inclined surface 1220 relative to the height direction H of the housing 1100 is β≥5°, it can be ensured that the pressure applied by the kettle 1300 to the inclined surface 1220 is large enough to meet the detection requirements of the pressure detection unit 1641.
[0160] In some embodiments, the inclination angle β of the inclined surface 1220 relative to the height direction H also satisfies the relationship: β≤15°. When the inclination angle β of the inclined surface 1220 relative to the height direction H of the housing 1100 is ≤15°, if the inclined surface 1220 protrudes from other walls of the door 1200, the thickness of the door 1200 in the region of the inclined surface 1220 can be avoided. If the inclined surface 1220 is a wall of a groove provided on the door 1200, the thickness of the housing 1100 in the region of the inclined surface 1220 can be avoided.
[0161] In some embodiments, the refrigerator 1000 can control the water injection mechanism 1400 via an MCU (Microcontroller Unit). For example, the MCU can receive signals detected by the position detection unit 1500, the liquid level detection unit 1620, the pressure detection mechanism 1640, and the pressure detection unit 1641, and generate corresponding control commands based on the received signals to control the water injection mechanism 1400.
[0162] In some embodiments, the water filling mechanism 1400 includes a water storage structure (not shown), a water outlet pipe (not shown), and a valve (not shown). The water storage structure can be disposed on the door 1200 and located above the kettle 1300. The water outlet pipe is disposed corresponding to a preset position. When the kettle 1300 is in the preset position, the water outlet pipe is connected to the kettle 1300. The valve can be disposed on the water outlet pipe. The MCU controls the opening / closing of the valve to fill or stop water filling into the kettle 1300.
[0163] Of course, the control method of the refrigerator 1000 over the water injection mechanism 1400, and the specific setting method of the water injection mechanism 1400, can also be other feasible methods disclosed in this field, and this application does not make specific limitations on them.
