[0001] Some embodiments of the present application relate to the technical field of household appliances, and particularly relate to a refrigerator. BACKGROUND

[0002] A refrigerator is a common household appliance that can keep food or other items at a constant low temperature. A water device can be arranged in the door body or the cabinet of the refrigerator to meet the user's demand for directly drinking cold water. The cabinet of the refrigerator is also provided with a water tank and a sensing piece for obtaining the liquid level height in the water tank. However, the detection end of the sensing piece is easy to be separated from the surface of the water tank, and the sensing piece has poor detection effect on the liquid level height in the water tank. SUMMARY

The refrigerator can improve the accuracy of water level detection in the water tank, and improve the user's experience.

[0004] In a first aspect, some embodiments of the present application provide a refrigerator, comprising:

[0005] a cabinet, a water device is arranged on the front side of the cabinet, and a mounting cavity is arranged on the front side of the cabinet;

[0006] a water level detection assembly, comprising:

[0007] a mounting seat, the mounting seat is arranged in the mounting cavity;

[0008] a resilient piece, a first end of the resilient piece is connected with the mounting seat, and a second end of the resilient piece is telescopic along a first direction;

[0009] a sensing piece, the sensing piece is arranged at the second end of the resilient piece;

[0010] a water tank, at least for supplying water to the water device;

[0011] wherein the water tank is slidably arranged in the mounting cavity along the first direction; when the water tank is located in the mounting cavity, the water tank is fixed with the cabinet; the resilient piece is in a compressed state, and the sensing piece is attached to the water tank.

[0012] The refrigerator of some embodiments of the present application comprises a cabinet, a water level detection assembly and a water tank. The water level detection assembly comprises a mounting seat, a sensing element and an elastic element. The water tank moves towards the rear side of the cabinet, the water tank pushes the sensing element to be close to the rear side of the cabinet, and the elastic element is contracted. When the water tank is fixed with the cabinet, the elastic element is in a compressed state, and the sensing element connected with the elastic element forces the sensing element to be attached to the water tank. Due to the elastic force of the elastic element, the connection between the sensing element and the water tank can be ensured, and the sensing element will not be loosened due to external force or vibration. In this way, the gap between the sensing element and the water tank during the detection process is avoided, thereby improving the accuracy of the water level detection in the water tank and improving the user experience.

[0013] In some embodiments of the present application, the mounting seat is provided with a mounting groove;

[0014] The water level detection assembly comprises a sliding structure, the sliding structure is fixedly connected with the sensing element, and the sliding structure can slide in the mounting groove in the first direction.

[0015] The water level detection assembly comprises a sliding structure, the sliding structure is fixedly connected with the sensing element, and the sliding structure provides protection for the sensing element to prevent it from being damaged by the external environment, thereby prolonging the service life of the sensing element. For example, the sliding structure can be an open shell, which facilitates the assembly of the sliding structure and the sensing element.

[0016] The sliding structure can slide in the mounting groove in the first direction. In this way, the sensing element can be conveniently installed in the mounting seat, and the sensing element can be conveniently repaired and replaced.

[0017] In some embodiments of the present application, the sliding structure comprises a sliding part and a mounting part connected with each other; the sliding part is surrounded outside the mounting part, one end of the sliding part away from the mounting part extends towards the rear side of the cabinet, and the outside of the sliding part is in contact with the inner wall of the mounting groove;

[0018] The mounting part can move towards or away from the groove bottom surface of the mounting groove in the first direction, the sensing element is arranged on the surface of the mounting part facing the groove bottom surface of the mounting groove, and the surface of the mounting part away from the groove bottom surface of the mounting groove is attached to the water tank.

[0019] The sensing element is arranged on the inner bottom surface of the sliding structure, which can ensure the reliability of the installation of the sensing element. The sensing element can accurately move with the sliding structure when the sliding structure moves, thereby realizing the water level detection of water tanks of different specifications. The compatibility and flexibility of the water level detection assembly are increased.

[0020] In some embodiments of the present application, the groove bottom surface of the mounting seat is provided with a mounting column, and the mounting column is fixed with the first end of the elastic element;

[0021] The surface of the sensing element away from the mounting part is fixed with the second end of the elastic element.

[0022] In this way, the elastic member can play a role to transmit the elastic force to the sensing member, so that the sensing member is attached to the water tank. The surface of the sensing member away from the bottom of the shell is fixed with the second end of the elastic member. When the elastic member is subjected to external force, the second end of the elastic member directly transmits the generated force to the sensing member, so that the sensing member is attached to the water tank.

[0023] In some embodiments of the present application, the sliding part is provided with a guide groove extending in the first direction;

[0024] The mounting seat is provided with a guide part fixedly connected with the inner wall of the mounting groove, and the guide part can slide in the guide groove in the first direction.

[0025] The guide part is matched with the guide groove to ensure the smoothness during assembly of the sliding structure. In this way, the friction and wear during assembly of the sliding structure are reduced, and the service life of the sliding structure is prolonged. At the same time, the setting of the guide groove and the guide part simplifies the installation process of the sliding structure to the mounting seat, and improves the installation efficiency of the sliding structure.

[0026] In some embodiments of the present application, the mounting seat is provided with a limiting part, and the limiting part is provided with a limiting groove extending in the first direction; the limiting part further comprises a blocking part located in the limiting groove;

[0029] The sliding part is provided with a clamping block which can slide in the limiting groove in the first direction. The clamping block can be used in cooperation with the limiting groove to enable the sliding structure to be quickly and stably installed in the mounting seat. The clamping block can slide in a specific direction in the limiting groove, which can ensure that the position of the sliding structure and the mounting seat is relatively accurate, so as to drive the sensing member and the water tank to be in a relatively accurate position, thereby improving the accuracy of water level detection of the water tank.

[0031] The water tank is provided with a connecting structure, and when the water tank is close to the rear side of the tank body, the water tank is fixed with the support through the connecting structure.

[0032] When the water tank is installed into the tank body in the first direction X, the water tank is fixed with the support through the connecting structure, and the water tank is fixed in the mounting cavity. In this way, the water tank can be stably installed in the tank body. This helps to prevent displacement of the water tank and damage to the connection between the water tank and the water pipe to prevent water leakage.

[0033] In some embodiments of this application, the housing is provided with a first mating part, and the water tank is provided with a second mating part; when the water tank is located inside the housing, the first mating part is located inside the second mating part, and the water tank is fixed to the housing at least through the mating first and second mating parts.

[0034] The bracket is equipped with multiple retractable claws, which work in conjunction with the connecting structure. When the water tank is close to the rear of the tank body, the multiple claws fix the connecting structure, and the water tank is fixed to the bracket at least by the cooperating claws and connecting structure.

[0035] This ensures that the water tank can be installed accurately and securely inside the tank, making the installation process simpler and faster, while also improving installation accuracy.

[0036] The water tank can be fixed to the tank body via a matching first and second mating parts. This ensures that the water tank can be installed accurately and securely inside the tank body, making the installation process simpler and faster, while also improving the accuracy of the water tank installation.

[0037] In some embodiments of this application, the surface of the water tank facing the rear side of the tank body is set as an inclined surface, and the top end of the inclined surface is closer to the rear side of the tank body than the bottom end of the inclined surface.

[0038] The water level detection component is equipped with a contact surface, which is inclined; when the water tank is close to the rear side of the tank body, the contact surface is in contact with the inclined surface.

[0081] As described in the background section, in related technologies, there is an increasing demand for refrigerators with drinking water or ice-making functions. These products can generally be divided into two categories based on their water supply method: one type uses an external water source to supply water to the refrigerator's water system, simply referred to as an external water refrigerator; the other type has a water tank inside the refrigerator, using the stored water in the tank as the water supply source, simply referred to as an internal water-filled refrigerator. Internal water-filled refrigerators are not limited by installation location and are simple to operate, making them more popular in the market.

[0082] For refrigerators with internal water supply, existing water supply systems typically employ a water tank combined with a water pump, water valves, and water circuit connectors. The water pump draws water from the tank and directs it to the water valves, which then distribute the water flow to the water-using devices (such as the drinking fountain and ice maker) via software control. When the water in the tank runs out or is insufficient to meet the next water demand, the water system can detect and monitor the remaining water level in advance, issuing a "water shortage" warning.

[0083] However, the sensor's detection end is prone to detaching from the water tank surface, resulting in poor accuracy in detecting the water level. In a "water shortage" state, the software system's water demand command can also cause unnecessary actions in electrical components such as the water pump and valves, affecting their lifespan. Furthermore, users triggering the water-using device may not elicit a corresponding response, negatively impacting the user experience.

[0084] In view of this, some embodiments of the refrigerator in this application include a cabinet, a water level detection component, and a water tank. The water level detection component includes a mounting base, a sensor, and an elastic element. When the water tank moves towards the rear of the cabinet, it pushes the sensor closer to the rear of the cabinet, causing the elastic element to contract. When the water tank is fixed to the cabinet, the elastic element is in a compressed state, and the sensor connected to the elastic element forces it to fit against the water tank. Due to the elastic force of the elastic element, the fit between the sensor and the water tank is ensured, preventing loosening due to external forces or vibrations. This avoids gaps between the sensor and the water tank during detection, thereby improving the accuracy of water level detection and enhancing the user experience.

[0085] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application.

[0091] The technical solutions of some 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 skilled in the art without creative effort are within the scope of protection of this application.

[0092] Reference Figure 1 As shown, some embodiments of this application provide a refrigerator 1, including a cabinet 10, which is the main structure of the refrigerator 1. The cabinet 10 can be equipped with a refrigeration system and can also be provided with storage space. The cabinet 10 can protect the internal refrigeration system and other components from the influence of the external environment, and at the same time, the heat insulation design can maintain the internal temperature of the refrigerator 1.

[0093] It should be noted that when a user stands in front of the refrigerator and observes it, if the door is closed, the view facing the refrigerator can be used as a reference. The user's direct front is opposite to the front of the refrigerator; the user's left side can be used to indicate the left side of the refrigerator, and the user's right side can be used to indicate the right side of the refrigerator. The direction parallel to the line connecting the front and rear sides of the refrigerator body 10 is defined as the first direction X; the direction parallel to the line connecting the right and left sides of the refrigerator body 10 is defined as the second direction Y; and the direction parallel to the line connecting the bottom and top sides of the refrigerator body 10 is defined as the third direction Z.

[0094] Reference Figure 2 As shown, a water-using device 11 is provided on the front side of the cabinet 10. The water-using device 11 is one of the functional modules inside the refrigerator 1. The water-using device 11 can be used to make ice or provide cold water.

[0095] For example, users can make cold drinks using the water device 11. The water device 11 expands the usage scenarios of the refrigerator 1 and improves the user's quality of life.

[0096] The front side of the cabinet 10 is provided with a mounting cavity 12. The mounting cavity 12 can be used to store and refrigerate food, and the mounting cavity 12 can be divided into a refrigeration area and a freezing area.

[0097] The refrigerator 1 includes a water tank 30, which is a component in the refrigerator 1 that stores water. The water tank 30 can be used to supply water to the water-using device 11.

[0098] For example, the water tank 30 can be made of plastic injection molding, which ensures the strength of the water tank 30 and reduces its weight.

[0099] For example, the water-using device 11 can be configured as a humidification module. The water tank 30 can be used to supply water to the humidification module so that the humidification module can increase the humidity of the refrigerator compartment through atomization, thereby maintaining the freshness of fruits and vegetables.

[0100] Furthermore, the water tank 30 can be located in the refrigeration area of ​​the cabinet 10, and the water tank 30 can be moved along the rear side of the cabinet 10 or away from it. The water tank 30 is detachably connected to the cabinet 10 to facilitate the water filling process of the water tank 30.

[0101] In other words, the water tank 30 can slide within the tank body 10 along the first direction X, which makes it easy for the water tank 30 to be removed from the tank body 10, making it convenient for users to clean, add water and perform other operations on the water tank 30.

[0102] The water tank 30 is slidably disposed within the mounting cavity 12 along the first direction X. The water tank 30 can slide within the mounting cavity 12, facilitating user operation.

[0103] For example, the housing 10 is equipped with electrical components such as a water pump and a water valve, and the housing 10 is also equipped with a water pipe between the water tank 30 and the water-using device 11. When the user uses the water-using device 11, the water-using device 11 issues relevant instructions to cause the water pump to draw water from the water tank 30, which flows through the water pipe between the water tank 30 and the water-using device 11 to the water valve, and then the water valve distributes the water flow to the water-using device 11 through software control.

[0104] In some embodiments of this application, reference is made to Figures 2-4 As shown, the box body 10 may include a food preservation drawer 50, which can extend the preservation time of food.

[0105] The food preservation drawer 50 is located inside the refrigerator body 10. Specifically, the food preservation drawer 50 can be placed in the refrigerator compartment of the refrigerator 1 to keep the food fresh.

[0106] For example, the food storage drawer 50 can be designed with slide rails, which allow the food storage drawer 50 to be pulled out and pushed in, making it convenient to take food out of the food storage drawer 50.

[0107] Reference Figure 3 As shown, the refrigerator 1 also includes a bracket 40 for supporting or fixing components inside the cabinet 10. For example, the bracket 40 can be used to support and fix components such as water pumps, water valves, and water pipes.

[0108] For example, the support 40 can be manufactured by die casting to give it high strength.

[0109] The bracket 40 is disposed in the mounting cavity 12, which has installation space to facilitate the installation of the bracket 40 and improve the assembly efficiency of the bracket 40.

[0110] The bracket 40 can be set at the rear of the water tank 30 to provide sufficient space for a larger water tank 30, thus meeting the volume requirements of the water tank 30.

[0111] In some embodiments, the bracket 40 is plate-shaped, with the plate surface facing or away from the front side of the cabinet 10. The bracket 40 can provide support for components such as the water tank 30, preventing them from shaking or shifting, thereby improving the overall stability and durability of the refrigerator 1.

[0112] Reference Figure 5 As shown, the water tank 30 is provided with a connecting structure 31, which is used to connect the water tank 30 to the bracket 40.

[0113] As mentioned above, the mounting base 21 can be set on the bracket 40, and the water tank 30 is connected to and limited by the connecting structure 31. This arrangement expands the functionality of the bracket 40.

[0114] The water tank 30 can be installed and removed by gripping the front side of the water tank 30. The connecting structure 31 can be set on the water tank 30 and face the rear side of the tank body 10 to facilitate the installation and removal of the water tank 30 from the tank body 10.

[0115] The water tank 30 is located inside the mounting cavity 12. When the water tank 30 approaches the rear side of the tank body 10 along the first direction X, the water tank 30 is inserted into the mounting cavity 12 and fixed to the bracket 40 through the connecting structure 31, thus fixing the water tank 30 inside the tank body 10. This helps to prevent the water tank 30 from shifting and prevents damage and leakage at the connection between the water tank 30 and the water pipe.

[0116] Continue to refer to Figure 5 As shown, the bracket 40 is provided with multiple claws 312, which can be used to fix the water tank 30.

[0117] The claw 312 can be mounted on the bracket 40 and face the front of the tank 10. This facilitates the installation of the water tank 30 inside the tank 10, enhances the reliability and convenience of the installation, and reduces the risk of leakage or loosening of the water tank 30 due to improper installation. It also facilitates the disassembly of the water tank 30.

[0118] The claws 312 can be retractable, allowing multiple retractable claws 312 to secure the water tank 30. The openings of the claws 312 can be retractable, and the claws 312 have a certain degree of elasticity, allowing them to open and close to facilitate the installation of the water tank 30.

[0119] The retractable claw 312 works in conjunction with the connecting structure 31. By engaging the claw 312 with the connecting structure 31, the water tank 30 is fixed inside the tank body 10, preventing the water tank 30 from moving.

[0120] For example, taking a plane perpendicular to the second direction Y as the cross-section, the cross-sectional shape of the connecting structure 31 can be set to be similar to a rhombus, that is, arched in the middle. The internal shape of the claw 312 is configured to cooperate with the connecting structure 31.

[0121] When the water tank 30 approaches the rear side of the tank body 10 along the first direction X, the water tank 30 is inserted into the tank body 10 and engaged with the connecting structure 31 by multiple claws 312, thus fixing the water tank 30 within the mounting cavity 12. This simplifies the installation steps of the water tank 30 and improves the installation efficiency. At the same time, it ensures the firmness of the connection between the water tank 30 and the tank body 10.

[0122] In some embodiments of this application, the claws 312 and the connecting structure 31 are configured to cooperate, thereby fixing the water tank 30 to the bracket 40. The connecting structure 31 is located between the multiple claws 312, so that the multiple claws 312 are spaced apart from each other. The multiple claws 312 deform, thereby generating elastic force. The multiple claws use the elastic force to clamp and fix the connecting structure 31, thereby fixing the water tank 30.

[0123] In other embodiments of this application, the water tank 30 and the bracket 40 are connected in other ways to fix them together. For example, the water tank 30 is provided with a magnetic component, and the bracket 40 is provided with a magnetic component. The installation and removal of the water tank 30 are achieved by changing the magnetic force of the magnetic component.

[0124] Reference Figure 6 and Figure 7 As shown, the housing 10 is provided with a first mating part 13, which provides a positioning point for the installation of the water tank 30.

[0125] The water tank 30 is provided with a second mating part 311, which is configured to cooperate with the first mating part 13 for further fixing the water tank 30.

[0126] The second mating part 311 can be provided on both sides of the water tank 30, and the second mating part 311 is provided at a rear position of the water tank 30 along the first direction X. This allows the water tank 30 to be installed in the tank body 10 with more even force.

[0127] The first mating part 13 and the second mating part 311 are disposed opposite to each other. The first mating part 13 may be configured as a protrusion facing the second mating part 311, and the second mating part 311 may be configured as a recess facing the first mating part 13. When the water tank 30 is placed into the tank body 10, the second mating part 311 can be inserted into the first mating part 13 to ensure that the water tank 30 is fixed.

[0128] For example, the first mating part 13 and the second mating part 311 are disposed opposite to each other. The first mating part 13 can be designed as a limiting spring protruding towards the second mating part 311. The limiting spring has an opening at one end facing the front of the refrigerator, and the other end facing the rear of the refrigerator is connected to the cabinet 10. The second mating part 311 can be configured as a recess facing the first mating part 13. The limiting spring can undergo elastic deformation to generate elastic force, causing the first mating part 13 to embed into the second mating part 311. This makes the installation process of the water tank 30 simple and quick, while improving the accuracy of the installation of the water tank 30.

[0129] Reference Figure 8 As shown, refrigerator 1 includes a water level detection component 20. The water level detection component 20 can monitor the water level in real time to prevent the water tank 30 from running low on water or overflowing. The water level detection component 20 can also detect the water level in the water tank 30 and send a reminder signal to the user. This improves the user experience.

[0130] Reference Figures 8-10 As shown, the water level detection component 20 further includes a mounting base 21. The mounting base 21 is used to provide support and fixation for the water level detection component 20, thereby improving the accuracy of water level detection in the water tank 30.

[0131] The mounting base 21 is located inside the mounting cavity 12, which facilitates the water level detection component 20 in detecting the water level in the water tank 30 and improves the working stability of the water level detection component 20.

[0132] The mounting base 21 can be mounted on the bracket 40, located on the front side of the bracket 40. This reduces interference from external factors on the water level detection component 20, ensuring the accuracy of the water level detection component 20.

[0133] The mounting base 21 is fixedly connected to the bracket 40, which can enhance the stability of the entire water level detection assembly 20.

[0134] In some embodiments of this application, the mounting base 21 and the bracket 40 can be integrally molded to reduce the number of parts in the refrigerator.

[0135] The water level detection component 20 includes a sensor 22. The sensor 22 is used to detect the water level in the water tank 30, so as to facilitate the addition of water to the water tank 30 or prevent the water tank 30 from overflowing.

[0136] The sensor 22 is positioned away from the rear side of the housing 10 to prevent physical damage to the sensor 22 and ensure that the sensor 22 can be used normally.

[0137] For example, the sensing element 22 can be configured as a photoelectric liquid level sensor. The photoelectric liquid level sensor utilizes the photoelectric principle to determine the water level by emitting a beam of light and detecting whether the light is blocked by liquid.

[0138] For example, the sensing element 22 can be configured as an ultrasonic level sensor. The ultrasonic level sensor utilizes the difference in propagation speed of ultrasonic waves in air and water, calculating the water level by emitting ultrasonic waves and measuring the time it takes for them to reflect back.

[0139] The water level detection assembly 20 also includes an elastic element 23. The elastic element 23 can undergo elastic deformation to generate elastic force, which can be used to press the components together.

[0140] The elastic element 23 includes a first end and a second end, which are located at opposite ends of the elastic element 23. The first end of the elastic element 23 is connected to the mounting base 21, and the sensing element 22 is disposed at the second end of the elastic element 23. It is readily understood that the water tank 30, the sensing element 22, the elastic element 23, and the mounting base 21 are sequentially arranged within the housing 10 along the first direction X.

[0141] When the elastic element 23 is compressed or rebounds, the second end of the elastic element 23 can move along the first direction X. The elastic element 23 can force the sensing element 22 to move along the first direction X.

[0142] The sensor 22 can move towards or away from the rear side of the tank 10. It is connected to the mounting base 21 via an elastic element 23. The first end of the elastic element 23 is fixed, while the second end of the elastic element 23 moves towards or away from the rear side of the tank 10 by extending and retracting along a first direction X. The second end of the elastic element 23 forces the sensor 22 to move towards or away from the rear side of the tank 10, so that the sensor 22 can measure the water level inside the tank 10.

[0143] For example, when the water tank 30 moves toward the rear side of the tank body 10, the water tank 30 first comes into contact with the sensor 22.

[0144] Next, the water tank 30 continues to move towards the rear of the tank body 10, pushing the sensor 22 closer to the rear of the tank body 10. At this time, the elastic element 23 deforms and is compressed under the push of the sensor 22.

[0145] Finally, when the water tank 30 is fixed to the tank body 10, the elastic element 23 is in a compressed state. The elastic element 23 generates an elastic force in the direction of the water tank 30. The elastic force acts on the sensing element 22, forcing the sensing element 22 to fit into the water tank 30.

[0146] The sensor 22 is in contact with the water tank 30 under the action of the elastic element 23. The elastic element 23 ensures a tight connection between the sensor 22 and the water tank 30, preventing loosening due to external forces or vibrations. This avoids gaps between the sensor 22 and the water tank 30 during the detection process, thereby improving the accuracy of water level detection in the water tank 30.

[0147] Production or installation errors may cause a micro-gap between the water tank 30 and the sensor 22. The elastic element 23 can generate elastic force when compressed. Under the action of the elastic force, the gap between the water tank 30 and the sensor 22 can be filled to ensure the accuracy of the sensor 22 in detecting the water level of the water tank 30.

[0148] The sensing element 22 is in contact with the water tank 30 under the action of the elastic element 23. This arrangement can also reduce the operation of electrical components such as water pumps and water valves, and extend the service life of these components.

[0149] When the water tank 30 moves toward the rear of the tank body 10, the compression process of the elastic element 23 can buffer and dampen the shock. When the water tank 30 contacts the sensor 22 and pushes it to move, the elastic element 23 can absorb part of the impact force and vibration, reducing some vibration damage to the water tank 30, the sensor 22 and the tank body 10, thus improving the durability and stability of the water level detection component 20.

[0150] The sensor 22 fits snugly against the water tank 30, ensuring that there are no small gaps between the water tank 30 and the housing 10, thus guaranteeing a tight seal at the connection. This prevents water from leaking from the connections between the water tank 30 and the water-using device 11.

[0151] Reference Figure 9 and Figure 10 As shown, the surface of the water tank 30 facing the rear side of the tank body 10 is set as an inclined surface 32, with the top end of the inclined surface 32 closer to the rear side of the tank body 10 than the bottom end of the inclined surface 32. That is, the water tank 30 is shaped to open outward along the third direction Z.

[0152] If the angle of the inclined surface 32 is less than 2 degrees, the design of the mold for the water tank 30 will be more complex, increasing the processing difficulty and thus reducing production costs. Moreover, this is not conducive to cleaning the inside of the water tank 30, and it is easy to create cleaning dead corners.

[0153] If the angle of the inclined surface 32 is greater than 5 degrees, the water tank 30 will open to a greater extent, which will reduce the load-bearing capacity of the water tank 30 and make the water tank 30 more susceptible to damage.

[0154] In some embodiments of this application, the angle of the inclined surface 32 can be set to 2 degrees to 5 degrees so that the sensing element 22 fits against the water tank 30.

[0155] For example, the angle of the inclined surface 32 can be set to 2 degrees to 2.5 degrees, 2.5 degrees to 3 degrees, 3 degrees to 3.5 degrees, 3.5 degrees to 4 degrees, 4 degrees to 4.5 degrees, or 4.5 degrees to 5 degrees. Specifically, the angle of the inclined surface 32 can be set to 2.0 degrees, 2.2 degrees, 2.4 degrees, 2.6 degrees, 2.8 degrees, 3.0 degrees, 3.2 degrees, 3.4 degrees, 3.6 degrees, 3.8 degrees, 4.0 degrees, 4.2 degrees, 4.4 degrees, 4.6 degrees, 4.8 degrees, or 5.0 degrees.

[0156] The water level detection component 20 is provided with a contact surface 243, which is inclined. When the water tank 30 is close to the rear side of the tank body 10, the contact surface 243 is in contact with the inclined surface 32. When the contact surface 243 of the water level detection component 20 is designed to match the inclined shape of the inclined surface 32 of the water tank 30, the two will form a larger contact area when in contact, which can improve the stability of the contact point.

[0157] When water is added to the water tank 30, the entire tank experiences a downward force. This causes the water tank 30 to tend to move downwards in the Z-direction. Due to the tight fit and tilted design between the mating surface 243 and the inclined surface 32, this downward movement pushes the water level detection component 20 to fit against the water tank 30, making the contact between them tighter and improving the measurement accuracy of the water level detection component 20.

[0158] Reference Figure 11 andFigure 12 As shown, the mounting base 21 is provided with a mounting groove 212, which can be used to fix parts. The mounting groove 212 makes the structure of the water level detection component 20 more compact, reduces the space occupied by the water tank 30, and ensures the capacity of the water tank 30.

[0159] The water level detection assembly 20 includes a sliding structure 24. The sliding structure 24 provides protection for the sensor 22, preventing it from being damaged by the external environment, thereby extending the service life of the sensor 22.

[0160] For example, the sliding structure 24 can be an open housing, which facilitates the assembly of the sliding structure 24 with the sensing element 22 and reduces the weight of the sliding structure 24.

[0161] The sliding structure 24 is fixedly connected to the sensing element 22. For example, the sliding structure 24 and the sensing element 22 can be connected by screws or the like to ensure the reliability of the connection. Alternatively, the sliding structure 24 and the sensing element 22 can be fixedly connected by clips or the like, which facilitates the disassembly, assembly, and replacement of the sensing element 22.

[0162] The sliding structure 24 can slide in the mounting groove 212 along the first direction X, so that the sensor 22 can move along the first direction X, so that the sensor 22 can detect the water level in the water tank 30.

[0163] Reference Figure 10 , Figure 11 and Figure 12 As shown, the sliding structure 24 includes a sliding part 241. The sliding part 241 can slide relative to the mounting groove 212 so that the sensor 22 can move along the first direction X, so that the sensor 22 can detect the water level in the water tank 30.

[0164] The sliding structure 24 includes a mounting part 242, which is used to mount the sensor 22 and fit against the water tank 30 so that the sensor 22 can detect the water level in the water tank 30.

[0165] The sliding part 241 is connected to the mounting part 242. The sliding part 241 surrounds the mounting part 242 to form an enclosing structure. This gives the sliding structure 24 a certain structural strength and stability.

[0166] For example, the mounting portion 242 is a thin plate structure, which reduces the weight of the sliding structure 24. The sliding portion 241 surrounds the outer side of the plate edge of the mounting portion 242.

[0167] The sliding part 241 extends towards the rear of the housing 10 from the end opposite to the mounting part 242, and the sliding part 241 has a certain height. The sliding part 241 provides a protective barrier for the sensor 22, preventing the sensor 22 from being impacted and damaged by the external environment.

[0168] The outer side of the sliding part 241 contacts the inner wall of the mounting groove 212. The sliding structure 24 can be embedded in the mounting groove 212. This reduces the space occupied by the mounting cavity 12, allowing more components to be arranged within it. Moreover, this arrangement conceals the mounting structure, reducing the clutter of the water level detection assembly 20 and improving its aesthetics.

[0169] For example, by contacting the outer side of the sliding portion 241 with the inner wall of the mounting groove 212, the sliding structure 24 can be embedded into the mounting groove 212 along the first direction X. To a certain extent, the outer side of the sliding portion 241 guides the assembly of the sliding structure 24, ensuring that the sliding structure 24 slides along a predetermined trajectory within the mounting groove 212, simplifying the assembly process of the sliding structure 24 and improving the production efficiency of the refrigerator 1.

[0170] The mounting part 242 can move closer to or further away from the bottom surface of the mounting groove 212 along the first direction. That is, the mounting part 242 needs to be able to move along the first direction X so that the mounting part 242 can drive the sensor 22 to move along the first direction X, so that the sensor 22 can detect the water level in the water tank 30.

[0171] Specifically, a sensor 22 is provided on the surface of the mounting part 242 facing the bottom of the mounting groove 212. In other words, the sensor 22 is provided on the inner bottom surface of the sliding structure 24, which ensures the reliability of the sensor 22's fixation. The sensor 22 can move along with the sliding structure 24, thereby realizing water level detection of water tanks 30 of different specifications. This increases the compatibility and flexibility of the water level detection assembly 20.

[0172] Reference Figure 13 As shown, specifically, the mounting part 242 may be provided with a mounting support column 2421. The mounting support column 2421 is used to fix the sensing element 22. The mounting support column 2421 makes the sensing element 22 fit against the bottom surface of the mounting groove 212.

[0173] For example, the mounting support column 2421 is provided with threaded holes, and the sensor 22 is attached to the bottom surface of the mounting groove 212 by screws cooperating with the mounting support column 2421.

[0174] For example, multiple mounting support columns 2421 can be provided, and the multiple mounting support columns 2421 are symmetrically arranged to ensure that the sensing element 22 fits against the bottom surface of the mounting groove 212 and that the sensing element 22 is subjected to more uniform force.

[0175] The mounting section 242 may be provided with a mounting limit rib 2422. The mounting limit rib 2422 can limit the position of the sensor 22 relative to the bottom surface of the mounting groove 212 to facilitate the installation of the sensor 22.

[0176] For example, the mounting limit ribs 2422 can be set in an "L" shape. Based on the corresponding position of the sensing element 22 on the bottom surface of the mounting groove 212, they are set at corresponding diagonal positions on the bottom surface of the mounting groove 212. This reduces the number of mounting limit ribs 2422 and lowers the weight of the sliding structure 24.

[0177] The mounting part 242 is provided with a mounting clip 2423. The mounting clip 2423 can be elastically deformed and is used to fix the sensing element 22.

[0178] For example, one or more mounting clips 2423 can be set, and the mounting support columns 2421 can be set relatively evenly and symmetrically to ensure that the sensing element 22 is subjected to relatively even force.

[0179] For example, the mounting buckle 2423, used in conjunction with the mounting limit rib 2422, can initially fix the sensor 22 to the bottom surface of the mounting groove 212. Then, the mounting support column 2421, in conjunction with the screw, makes the sensor 22 fit against the bottom surface of the mounting groove 212.

[0180] The surface of the mounting part 242, which faces away from the bottom of the mounting groove 212, is in contact with the water tank 30. In other words, the outer bottom surface of the sliding structure 24 is in contact with the water tank 30. Because the mounting part 242 separates the sensor 22 from the water tank 30, the distance between them is relatively short, resulting in higher detection efficiency and accuracy for the sensor 22.

[0181] Mounting post 211 is provided on the bottom surface of the groove of mounting base 21. Mounting post 211 is used to mount elastic element 23.

[0182] Specifically, the mounting post 211 is fixed to the first end of the elastic element 23. The mounting post 211 is provided on the bottom surface of the groove of the mounting base 21 to support and fix the elastic element 23. This ensures that the elastic element 23 can function, transmitting elastic force to the sensing element 22, causing the sensing element 22 to fit against the water tank 30.

[0183] In some embodiments of this application, the elastic element 23 can be configured as a spring sheet, which has a simple structure and low cost. The elastic element 23 can also be configured as a rubber elastic pad, which can not only make the sensor 22 fit against the water tank 30, but also reduce the impact of the tank body 10 on the vibration of the sensor 22.

[0184] In other embodiments of this application, the elastic element 23 can be configured as a spring. Springs are widely used. The elastic element 23 is symmetrically mounted within the mounting post 211. A cross-shaped reinforcing rib is provided inside the mounting post 211 to improve the stability of the elastic element 23.

[0185] The length of the elastic element 23 embedded in the mounting post 211 is set as H. The initial length of the elastic element 23 is L. H is usually taken between 1 / 4L and 1 / 2L to ensure the stability of the fixed elastic element 23. For example, H can be taken between 1 / 4L and 5 / 16L, 5 / 16L and 6 / 16L, 6 / 16L and 7 / 16L, or 7 / 16L and 1 / 2L.

[0186] If H is less than 1 / 4L, the elastic element 23 may undergo torsional deformation in a direction other than the first direction X during the compression deformation process, which may cause the sensing element 22 to warp or get stuck.

[0187] If H is greater than 1 / 2L, the deformation of the elastic element 23 under compression is small, and the displacement of the sensing element 22 along the first direction X is small, resulting in a small gap between the sensing element 22 and the water tank 30, which reduces the detection accuracy of the sensing element 22.

[0188] The surface of the sensor 22 facing away from the bottom 242 of the shell is fixed to the second end of the elastic element 23. When the elastic element 23 is subjected to an external force, the second end of the elastic element 23 directly transmits the force to the sensor 22, thereby achieving the contact between the sensor 22 and the water tank 30.

[0189] For example, when the water tank 30 is installed into the tank body 10, the water tank 30 moves toward the rear side of the tank body 10. Then, the water tank 30 contacts the outer surface of the mounting portion 242 and pushes the sliding portion 241 to move along the first direction X. Next, the sensing element 22 moves along with the sliding portion 241, and the second end of the elastic element 23, which contacts the sensing element 22, moves along the first direction X. Finally, the elastic element 23 is compressed and deformed. The elastic element 23 generates a reverse elastic force acting on the sensing element 22, forcing the sensing element 22 to fit against the water tank 30, ensuring the accuracy of the water level detection in the water tank 30.

[0190] Reference Figure 11 , Figure 12 and Figure 13 As shown, the sliding part 241 is provided with a guide groove 2411, which is used for the sliding structure 24 to be assembled into the mounting groove 212 of the mounting base 21.

[0191] The guide groove 2411 extends along the first direction X. The sliding part 241 is provided with one or more guide grooves 2411, which are relatively evenly distributed in the sliding part 241, so that the sliding structure 24 can be installed into the mounting groove 212 and prevent the sliding structure 24 from getting stuck during installation.

[0192] The mounting base 21 is provided with a guide part 2111, which works in conjunction with the guide groove 2411 to facilitate the sliding structure 24 to be installed into the mounting groove 212.

[0193] The guide portion 2111 is fixedly connected to the inner wall of the mounting groove 212. The mounting groove 212 is provided with one or more guide portions 2111, and the mounting grooves 212 are relatively evenly distributed on the inner wall of the mounting groove 212 to prevent the sliding structure 24 from being misaligned during installation.

[0194] The guide portion 2111 extends along the first direction X on the inner wall of the mounting groove 212 to ensure that the guide portion 2111 and the guide groove 2411 have a suitable mating length, so as to reduce the installation difficulty of the sliding structure 24 into the mounting groove 212.

[0195] The guide portion 2111 can slide within the guide groove 2411 along the first direction X, so that the sliding structure 24 can be smoothly installed into the mounting groove 212. This ensures the smoothness of the assembly process of the sliding structure 24, reduces friction and wear during the assembly process, and extends the service life of the sliding structure 24.

[0196] Meanwhile, the matching arrangement of the guide groove 2411 and the guide part 2111 simplifies the installation process of assembling the sliding structure 24 onto the mounting base 21 and improves the installation efficiency of the sliding structure 24.

[0197] Continue to refer to Figure 11 , Figure 12 and Figure 13 As shown, the mounting base 21 is provided with a limiting element 2112, which is used for limiting and guiding the sliding structure 24 during installation.

[0198] Mounting base 21 is provided with one or more limiting members 2112. Specifically, mounting base 21 is provided with two limiting members 2112 and the two limiting members 2112 are symmetrically arranged to improve the stability of the sliding structure 24 during installation.

[0199] For example, one end of the limiting member 2112 is connected to the mounting base 21, while the other end of the limiting member 2112 is in a free state. The other end of the limiting member 2112 can undergo a small displacement, which can improve the fault tolerance of the installation of the limiting member 2112.

[0200] The limiting member 2112 is provided with a limiting groove 21121, which is hollow. The limiting groove 21121 is used to limit the movement trajectory of the sliding part 241 and ensure the accuracy of the sliding part 241.

[0201] The limiting groove 21121 extends along the first direction X, and the limiting groove 21121 is provided with a suitable length to ensure that the limiting groove 21121 can play a limiting role.

[0202] The sliding part 241 is provided with a locking block 2412, which can slide within the limiting groove 21121 along the first direction. The locking block 2412 can be used in conjunction with the limiting groove 21121 to improve the efficiency of the sliding structure 24 being installed in the mounting base 21.

[0203] Specifically, the card block 2412 can slide along the direction inside the groove of the limiting groove 21121, which can ensure that the position of the sliding structure 24 and the mounting base 21 remains relatively accurate, thereby driving the sensor 22 and the water tank 30 to be in a relatively accurate state, improving the accuracy of water level detection in the water tank 30.

[0204] The limiting member 2112 also includes a blocking part 21122, which is located within the limiting groove 21121. The blocking part 21122 is disposed at the free end of the limiting member 2112. The blocking part 21122 is used to limit the position of the locking block 2412 and ensure that the sliding structure 24 is mounted on the mounting base 21.

[0205] For example, when the water tank 30 is close to the rear side of the tank body 10, the water tank 30 is in contact with the mounting portion 242 of the sliding structure 24, and the sliding structure 24 causes the elastic member 23 to be compressed and deformed. With the sliding structure 24 in contact with the water tank 30, the sensor 22 can detect the water level inside the water tank 30. At this time, the sliding structure 24 can move as the water tank 30 approaches the rear side of the tank body 10, and the locking block 2412 does not contact the blocking portion 21122.

[0206] When the water tank 30 moves away from the rear side of the tank body 10, the elastic element 23 is compressed and has an elastic force, allowing the sliding structure 24 to move with the water tank 30 towards the front side of the tank body 10. The guide part 2111 cooperates with the guide groove 2411, and the locking block 2412 is located in the limiting groove 21121, causing relative movement between the sliding structure 24 and the mounting base 21. When the locking block 2412 is blocked by the blocking part 21122, the locking block 2412 and the blocking part 21122 abut against the surface of the front side of the tank body 10, preventing the sliding structure 24 from falling off the mounting base 21.

[0207] In some embodiments of this application, reference is made to Figure 5 and Figure 10 As shown, when the water tank 30 is installed in the mounting cavity 12, after the water tank 30 is assembled in place, the above-mentioned forces reach a state of equilibrium, then F s =F w +F k ;

[0208] F s - The force applied to the water tank 30 by the elastic element 23;

[0209] F w - Static friction between water tank 30 and tank body 10;

[0210] F k - Static friction between the bracket's claw 312 and the water tank's connecting structure 31.

[0211] When the water tank 30 is installed inside the tank 10, the elastic element 23 is in a compressed state so that the water level detection component 20 fits against the water tank 30, thereby improving the accuracy of water level detection inside the water tank 30.

[0212] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
