Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of household appliances, and more particularly relates to a water storage mechanism and a refrigerator. BACKGROUND

[0002] The refrigerator is a refrigeration device that keeps a constant low temperature, and can be used to store various beverages, such as beer, juice, soda, etc., so that people can enjoy cool drinks at any time in hot weather. Some refrigerator products are also equipped with a water storage mechanism, so that the refrigerator can continuously supply low-temperature beverages to users.

[0003] In the related art, when the water level in the water storage kettle of the water storage mechanism is low, the water storage mechanism can be replenished by the water supply system, and the water level in the water storage kettle can be monitored by the detector arranged in the water storage kettle to automatically stop water replenishment. However, after a long time of use, the detector is prone to damage, resulting in inaccurate detection results. UTILITY MODEL CONTENT

[0004] The purpose of the embodiments of the present application is to provide a water storage mechanism and a refrigerator to solve the technical problem that the detector is prone to damage after a long time of use in the prior art, resulting in inaccurate detection results.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present application is:

[0006] In a first aspect, a water storage mechanism is provided, comprising:

[0007] A water storage kettle, the water storage kettle comprising:

[0008] A water storage cavity for storing liquid, the water storage cavity being provided with a water inlet for communicating with a water supply system;

[0009] An induction cavity arranged on one side of the water storage cavity, the induction cavity storing gas, and at least part of the cavity wall of the induction cavity being a first flexible wall, the gas pressure in the induction cavity changing with the liquid pressure in the water storage cavity, and the first flexible wall deforming with the change in the gas pressure in the induction cavity;

[0010] A sensor arranged outside the water storage cavity and the induction cavity, the sensor being used to detect the deformation amount of the first flexible wall, and the sensor also being used to communicate with the water supply system to transmit the deformation information obtained by detection to the water supply system.

[0011] By adopting the technical scheme of the embodiment, the sensor is arranged outside the induction cavity and the water storage cavity, so that the probability of the sensor contacting with the liquid in the water storage kettle is reduced, and a relatively dry use scene is provided for the sensor, so that the possibility of the sensor being damaged by moisture entering the inside of the sensor is reduced, the detection accuracy of the sensor is ensured, and the service life of the sensor is improved. In addition, the relatively dry use scene provided for the sensor can also improve the dryness degree in the inside of the sensor, so that the possibility of bacteria breeding in the inside of the sensor due to moisture is reduced, the cleaning of the water storage kettle is ensured, and the storage time of the liquid in the water storage kettle is prolonged. The first flexible wall is arranged on the water storage kettle, and when the air pressure in the induction cavity changes, the first flexible wall can be deformed. Therefore, the deformation degree of the first flexible wall can reflect the change degree of the air pressure in the induction cavity, and then reflect the liquid level in the water storage cavity. When the first flexible wall is deformed to a certain degree, the sensor can be triggered to send information to the water supply system, so that the water supply to the water storage kettle is automatically stopped, and the probability of liquid overflowing from the water storage kettle due to excessive water supply is reduced. In addition, the first flexible wall can separate the sensor and the induction cavity, that is, the first flexible wall can separate the water vapor in the water storage kettle from the sensor, so that the sensor can work in a relatively dry environment, and the service life of the sensor is prolonged.

[0012] In some embodiments, the first flexible wall is arranged spaced apart from the sensor, and when the pressure in the induction cavity increases, the first flexible wall protrudes towards the sensor. The sensor senses the pressure change in the induction cavity by detecting the distance between the sensor and the first flexible wall.

[0013] By adopting the technical scheme of the embodiment, when the liquid level in the water storage cavity rises, the first flexible wall can protrude outward from the center of the induction cavity. Therefore, the protrusion degree of the first flexible wall can reflect the liquid level in the water storage cavity. When the first flexible wall is protruded to a certain degree, the sensor can be triggered to send information to the water supply system, so that the water supply to the water storage kettle is automatically stopped, and the probability of liquid overflowing from the water storage kettle due to excessive water supply is reduced.

[0014] In some embodiments, along the height direction of the water storage cavity, the first flexible wall is the top wall of the induction cavity, and the sensor is arranged spaced apart above the first flexible wall.

[0015] By adopting the technical scheme of the embodiment, the possibility of the first flexible wall being submerged by the liquid in the water storage cavity is reduced, the influence of the liquid pressure in the water storage cavity on the appearance of the first flexible wall is reduced, and the detection accuracy is improved.

[0016] In some embodiments, the water storage kettle further comprises a sensing member, the sensing member is arranged on the first flexible wall and outside the induction cavity, the sensing member is matched with the sensor, the first flexible wall protrudes and drives the sensing member to move, and the sensor detects the distance between the sensor and the first flexible wall by sensing the sensing member.

[0017] By adopting the technical scheme of the embodiment, the sensing member is arranged on the first flexible wall and outside the induction cavity, so that the sensing member is not in contact with the liquid, which can reduce the pollution of the sensing member to the liquid, and can also reduce the probability of the liquid entering the sensing member and the possibility of bacterial breeding in the sensing member; the sensing member matched with the sensor can be recognized by the sensor when the sensing member enters the detection range of the sensor, so as to trigger the sensor, which helps to improve the detection accuracy of the sensor.

[0021] By adopting the technical scheme of the embodiment, the sensing member is a magnetic member, and the sensor is a magnetic switch, so that the sensing member and the sensor can be inducted by magnetism, for example, the peripheral part of the sensing member has a magnetic field, when the sensing member moves towards the sensor, the distance between the sensing member and the sensor is reduced, when the distance between the two is reduced to a certain value, the sensor enters the magnetic field range of the sensing member, at this time, the magnetic element in the sensor is triggered by the magnetic field of the sensing member, that is, only when the sensor enters the magnetic field range of the sensing member, the sensor can be triggered, so that the detection accuracy of the sensor can be ensured.

[0022] In some embodiments, the middle part of the first flexible wall is connected with the sensing member, and the thickness of the middle part of the first flexible wall is greater than the thickness of the edge part of the first flexible wall.

[0023] By adopting the technical scheme of the embodiment, the thickness of the middle part of the first flexible wall is greater than the thickness of the edge part of the first flexible wall, which can increase the thickness of the connection part of the first flexible wall and the sensing member, so as to enhance the strength of this area and improve the connection stability of the first flexible wall and the sensing member, in addition, the thickness of the edge part of the first flexible wall is small, and the strength of this area is low, when the pressure in the induction cavity becomes large, the edge part of the first flexible wall can be deformed, so that the first flexible wall can protrude outward from the center of the induction cavity, thereby driving the sensing member to move to trigger the sensor.

[0024] In some embodiments, a first step surface is arranged on one side of the first flexible wall facing the inductor, and a groove is arranged on the other side of the first flexible wall away from the inductor.

[0025] By adopting the technical solutions of the present embodiment, the first step surface arranged on the first flexible wall can facilitate judging the thickness of each region of the first flexible wall, thereby facilitating the installation of the inductor on the first flexible wall; the groove arranged on the first flexible wall can thin the local thickness of the first flexible wall, thereby improving the flexibility and elasticity of the first flexible wall; in addition, the arrangement of the first step surface and the groove can make the cross section of the first flexible wall present a stepped shape, which can help to increase the overall strength of the first flexible wall, thereby helping to improve the supporting capacity of the first flexible wall for the inductor.

[0026] In some embodiments, the water storage kettle further comprises a connecting piece, and the inductor is connected to the first flexible wall through the connecting piece.

[0029] In some embodiments, the bottom of the inductor cavity is provided with a first opening, the first opening is in communication with the water storage cavity, and the liquid in the water storage cavity can enter the inductor cavity through the first opening to increase the pressure in the inductor cavity.

[0030] By adopting the technical solutions of the present embodiment, the first opening is arranged at the bottom of the inductor cavity, and the first opening is in communication with the water storage cavity; when there is no water or the water amount in the water storage cavity is small, the gas in the inductor cavity can enter the water storage cavity through the first opening and enter the external environment through the water inlet of the water storage cavity, that is, the inductor cavity is in communication with the external environment, the gas in the inductor cavity can flow to the external environment, and fresh air in the external environment can also enter the inductor cavity, thereby reducing the possibility of bacteria breeding in the inductor cavity.

[0031] In some embodiments, the water storage kettle further comprises:

[0032] The inductor assembly comprises:

[0033] A protective cover is provided with a protective cavity;

[0034] The first flexible wall is arranged in the protective cavity, and a peripheral portion of the first flexible wall is sealingly connected to an inner wall of the protective cavity.

[0035] A partition plate is arranged in an inner cavity of the water storage kettle, and the protective cover is sealingly connected to the partition plate, so that the protective cover, the first flexible wall and the partition plate enclose the induction cavity.

[0036] By adopting the technical scheme of the embodiment, the first flexible wall is arranged in the protective cavity of the protective cover, the protective cover can protect the first flexible wall, the first flexible wall can be spaced from the external environment, that is, the first flexible wall can not be exposed to the external environment, so that the influence of the external environment on the deformation of the first flexible wall can be reduced, and the detection accuracy of the sensor can be improved. In addition, the protective cover is sealingly connected to the partition plate, that is, the first flexible wall is indirectly connected to the partition plate through the protective cover. When the first flexible wall needs to be replaced, the protective cover can be removed from the partition plate, so that the maintenance difficulty of the water storage kettle can be reduced.

The change of the liquid pressure in the water storage cavity can be transmitted to the induction cavity through the deformation of the second flexible wall, so that the pressure in the induction cavity changes correspondingly, so that the sensor can be used to detect the pressure in the induction cavity to automatically stop water replenishment.

[0063] In order to make the technical problems to be solved by the present application, the technical solutions and beneficial effects clearer, the following will be further described in detail in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application. Figures 1 to 11

[0066] ​In addition, the terms "first", "second", etc. are used only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, the meaning of "multiple groups" is two groups or more, the meaning of "multiple pieces" is two pieces or more, and the meaning of "several" is one or more, unless otherwise explicitly and specifically limited.

[0067] A refrigerator is a refrigeration device that maintains a constant low temperature, which can refrigerate various beverages such as beer, juice, soda, etc., so that people can enjoy cool drinks at any time in hot weather. Some refrigerator products are also equipped with a water storage mechanism, so that the refrigerator can continuously supply low-temperature drinks to the user.

[0068] The water storage mechanism usually includes a water storage kettle and a water supply system in communication with the water storage kettle, which can supplement water to the water storage kettle through the water supply system when the water in the water storage kettle is less.

[0069] In the related art, the kettle body of the water storage kettle is inlaid with a transparent piece, which can be observed by the naked eye through the transparent piece to determine the water level in the water storage kettle, and then manually control the stop of water replenishment. However, this method is not accurate and can cause overfilling. Therefore, in some products, the kettle body is also provided with a detection cavity, which is in communication with the water storage cavity, and a detector is arranged in the detection cavity. The detector detects the water level or pressure change in the detection cavity to monitor the water level in the water storage cavity. Compared with manual observation and judgment of the water level, the detection accuracy of the detector is improved. However, the detector is set in an environment with high humidity, and the sealing element in the detector can easily age after long-term use, which reduces the sealing performance of the detector. During use of the water storage kettle, the detector with reduced sealing performance is used in a high-humidity environment, which is easy to be damaged by moisture, resulting in inaccurate detection results. Therefore, when the liquid level in the water storage kettle rises to the maximum height, the water supply system may not be able to stop water injection in time, which can easily cause water in the water storage kettle to overflow and pollute the inside of the refrigerator. In addition, the moisture in the detector can also breed bacteria and pollute the water storage kettle.

[0070] However, after long time use, the seal in the detector is prone to aging, leading to reduced sealing performance of the detector. During use of the water storage kettle, there is certain water in the detection cavity, which is prone to evaporation, leading to high humidity in the detection cavity. The detector with reduced sealing performance is prone to dampness and damage in a high-humidity environment, leading to inaccurate detection results. Thus, when the liquid level in the water storage kettle rises to the maximum height, the water supply system may fail to stop water supply in time, leading to water overflow in the water storage kettle and pollution of the refrigerator.

[0071] Therefore, the embodiments of the present application provide a water storage mechanism, which comprises a water storage kettle and a sensor. The water storage kettle comprises a water storage cavity and a sensing cavity. The water storage cavity is used for storing liquid. The water storage cavity is provided with a water inlet, which is used for communicating with a water supply system. The sensing cavity is arranged on one side of the water storage cavity. The sensing cavity stores gas. The gas pressure of the sensing cavity increases with the increase of the liquid pressure in the water storage cavity. The sensor is arranged outside the water storage cavity and the sensing cavity. The sensor is used for detecting the pressure change in the sensing cavity. The sensor is also used for being communicatively connected with the water supply system, so as to transmit the detected pressure change information to the water supply system.

[0072] The water storage mechanism provided by the embodiments of the present application can reduce the probability of contact between the sensor and the liquid in the water storage kettle by arranging the sensor outside the sensing cavity and the water storage cavity. Thus, a relatively dry use scenario can be provided for the sensor, which reduces the possibility of water entering the sensor and damaging the sensor. Thus, the detection accuracy of the sensor can be ensured, and the service life of the sensor can be improved. In addition, the relatively dry use scenario provided for the sensor can also improve the dryness degree inside the sensor, thereby reducing the possibility of bacteria breeding due to dampness inside the sensor, helping to ensure the cleanliness of the water storage kettle and prolong the preservation time of the liquid in the water storage kettle. The first flexible wall is arranged on the water storage kettle. When the gas pressure in the sensing cavity changes, the first flexible wall can deform. Thus, the deformation degree of the first flexible wall can reflect the change degree of the gas pressure in the sensing cavity, and further reflect the liquid level height in the water storage cavity. When the first flexible wall deforms to a certain degree, the sensor can be triggered to send information to the water supply system. Thus, automatic water supply to the water storage kettle can be realized, and the probability of liquid overflow from the water storage kettle due to excessive water supply can be reduced. In addition, the first flexible wall can separate the sensor and the sensing cavity, that is, the first flexible wall can isolate the water vapor in the water storage kettle from the sensor, so that the sensor can work in a relatively dry environment, which helps to prolong the service life of the sensor.

[0073] Please refer to Figures 1 to 3 for a description of the water storage mechanism provided by the embodiments of the present application.

[0074] The water storage mechanism provided by the application comprises a water storage kettle 2 and a sensor 11. The water storage kettle 2 comprises a water storage cavity 212 and a sensing cavity 213. The water storage cavity 212 is used for storing liquid. For example, the water storage cavity 212 can store drinks or pure water. The water storage cavity 212 is provided with a water inlet 222 which is used for communicating with a water supply system (not shown in the figure). The water supply system can supplement water to the water storage cavity 212 through the water inlet 222. The sensing cavity 213 is arranged on one side of the water storage cavity 212. The sensing cavity 213 stores gas. The cavity wall of the sensing cavity 213 is at least partially flexible, which is a first flexible wall 23. The gas pressure of the sensing cavity 213 is related to the liquid pressure in the water storage cavity 212. When the liquid pressure in the water storage cavity 212 increases, the gas pressure of the sensing cavity 213 increases accordingly. When the liquid pressure in the water storage cavity 212 decreases, the gas pressure of the sensing cavity 213 decreases accordingly. The first flexible wall 23 can sense the change of the gas pressure in the sensing cavity 213 and deforms with the change of the gas pressure in the sensing cavity 213. The sensor 11 is arranged outside the water storage cavity 212 and the sensing cavity 213. The sensor 11 is used for detecting the deformation amount of the first flexible wall 23. The sensor 11 is also used for being communicatively connected with the water supply system to transmit the deformation information obtained by detection to the water supply system.

[0075] In the embodiment, the water storage mechanism comprises the water storage kettle 2 and the sensor 11. The water storage kettle 2 comprises the water storage cavity 212 and the sensing cavity 213. The water storage cavity 212 is used for storing liquid. The water storage cavity 212 is provided with the water inlet 222 which is used for communicating with the water supply system. The sensing cavity 213 is arranged on one side of the water storage cavity 212. The sensing cavity 213 stores gas. The cavity wall of the sensing cavity 213 is at least partially the first flexible wall 23. The gas pressure of the sensing cavity 213 changes with the change of the liquid pressure in the water storage cavity 212. The sensor 11 is arranged outside the water storage cavity 212 and the sensing cavity 213. The sensor 11 is used for detecting the deformation amount of the first flexible wall 23. The sensor 11 is also used for being communicatively connected with the water supply system to transmit the deformation information obtained by detection to the water supply system.

[0076] It should be noted that the sensor 11 is communicatively connected with the water supply system. The communication connection can be achieved by wired means such as wires and the like, or by wireless means such as Bluetooth, Wi-Fi, mobile network and the like. The detection result of the sensor 11 can be transmitted to the water supply system. After receiving the information detected by the sensor 11, the water supply system can make a corresponding response action, for example, stopping water supplement to the water storage kettle 2.

[0077] It should be noted that the deeper the position from the liquid surface, the greater the pressure generated by the liquid, and correspondingly, the greater the pressure exerted by the liquid on a certain area. Conversely, when the liquid level in the water storage cavity 212 gradually rises, the distance between the water at the bottom of the water storage cavity 212 and the liquid level gradually increases. Thus, the pressure of the water at the bottom of the water storage cavity 212 is greater, and as the amount of water in the water storage cavity 212 gradually increases, the overall pressure of the liquid in the water storage cavity 212 also gradually increases. When the water supply system supplies water to the water storage cavity 212, the amount of water in the water storage cavity 212 increases, and the liquid level in the water storage cavity 212 gradually rises. In this embodiment, the sensing cavity 213 can perceive the change in the liquid level height in the water storage cavity 212 through the change in the internal air pressure. When the liquid level in the water storage cavity 212 rises to the highest value, the air pressure in the sensing cavity 213 reaches a condition that can trigger the sensor 11. At this time, the sensor 11 is triggered to send information to the water supply system, and the water supply system can stop supplying water.

[0078] It should be noted that the sensor 11 can detect the pressure change information in the sensing cavity 213 in various ways. For example, when the first flexible wall 23 deforms, the distance between the first flexible wall 23 and the sensor 11 changes. The sensor 11 can be a distance sensor that detects the pressure change in the sensing cavity 213 by detecting the distance change. For example, when the pressure in the sensing cavity 213 increases, the first flexible wall 23 can deform, and the distance between the first flexible wall 23 and the sensor 11 changes when the first flexible wall 23 deforms. That is, the change in the pressure in the sensing cavity 213 can be reflected by the distance between the first flexible wall 23 and the sensor 11. The corresponding relationship between the distance value of the distance sensor and the liquid level height value of the water storage cavity 212 can be obtained in advance through experiments, and the distance value corresponding to the highest liquid level height of the water storage cavity 212 is pre-stored in the distance sensor.

[0079] In addition, a component adapted to the sensor 11 can also be provided on the first flexible wall 23. When the first flexible wall 23 deforms, the component can enter the detection range of the sensor 11, and the sensor 11 can recognize the component. At this time, the sensor 11 can be triggered, and the sensor can send information to the water supply system to stop supplying water to the water kettle 2.

[0080] It should be noted that in some embodiments, the sensing cavity 213 can not be a closed cavity, and the sensing cavity 213 can be in communication with the water storage cavity 212 and the external environment. In other embodiments, the sensing cavity 213 can be a closed cavity.

[0081] For example, when the induction cavity 213 is not a closed cavity, the induction cavity 213 can be in communication with the water storage cavity 212 through an opening. When the water supply system supplies water to the water storage kettle 2, the liquid in the water storage cavity 212 can flow into the induction cavity 213 through the opening. As the liquid level in the induction cavity 213 continues to rise, the opening is gradually blocked by the liquid, and a part of the gas is sealed in the induction cavity 213. As the water supply system continues to supply water to the water storage kettle 2, the liquid in the water storage cavity 212 continues to enter the induction cavity 213 to raise the liquid level of the induction cavity 213, and the gas sealed in the induction cavity 213 is continuously compressed, so that the air pressure in the induction cavity 213 continues to increase. In another embodiment, when the induction cavity 213 is a closed cavity, the induction cavity 213 is not in communication with the water storage cavity 212 and the external environment. At this time, the induction cavity 213 can be filled with a certain amount of gas, and the induction cavity 213 and the water storage cavity 212 can be separated by a flexible membrane. At this time, the induction cavity 213 is equivalent to a gas bag structure. When the liquid level in the water storage cavity 212 gradually rises, the part of the induction cavity 213 immersed in the liquid gradually increases, and the extrusion of the liquid in the water storage cavity 212 on the membrane gradually increases, so that the membrane extrudes the induction cavity 213. In this way, the volume of the induction cavity 213 is compressed, and the pressure in the induction cavity 213 increases.

[0082] It should be noted that in some embodiments, the sensor 11 can be installed on the water storage kettle 2, and in other embodiments, the sensor 11 can not be installed on the water storage kettle 2.

[0083] It should be noted that the water supply system can include a water pipe, one end of the water pipe is in communication with the external pipeline, and the other end of the water pipe is provided with a water inlet. The water inlet can be in communication with the water inlet 222 of the water storage cavity 212. An electric valve can be provided on the water pipe, and the electric valve can be connected with the sensor 11. When the electric valve is opened, the water supply system can supply water to the water storage kettle 2. When the sensor 11 is triggered, the sensor 11 can send information to the electric valve to close the electric valve, so that the water supply system can stop supplying water to the water storage kettle 2.

[0084] It should be noted that the first flexible wall 23 is a solid component with a certain thickness, which can be made of a flexible or elastic membrane, or made of a flexible or elastic plate. In some embodiments, the first flexible wall 23 can have elasticity. When the pressure in the induction cavity 213 increases, the first flexible wall 23 deforms elastically under the action of the pressure. In other embodiments, the first flexible wall 23 can not have elasticity. The area of the first flexible wall 23 can be increased and formed into a wrinkle. When the pressure in the induction cavity 213 increases, the wrinkle of the first flexible wall 23 is stretched to deform under the action of the internal pressure of the induction cavity 213.

[0085] It should be noted that when the liquid level in the water storage cavity 212 rises, the liquid pressure in the water storage cavity 212 increases, at this time, the compression force of the gas in the induction cavity 213 increases, and the gas in the induction cavity 213 is compressed and pressurized, so that the first flexible wall 23 is deformed. Thus, the deformation degree of the first flexible wall 23 is related to the liquid level in the water storage cavity 212, and the higher the liquid level in the water storage cavity 212, the greater the deformation degree of the first flexible wall 23.

[0086] The water storage mechanism provided by the embodiments of the present application can reduce the probability of contact between the sensor 11 and the liquid in the water storage kettle 2 by arranging the sensor 11 outside the induction cavity 213 and the water storage cavity 212. Thus, a relatively dry use environment can be provided for the sensor 11, which reduces the possibility of damage to the sensor 11 caused by moisture entering the interior of the sensor 11. Thus, the detection accuracy of the sensor 11 can be ensured, and the service life of the sensor 11 can be improved. In addition, providing a relatively dry use environment for the sensor 11 can also improve the dryness inside the sensor 11, thereby reducing the possibility of bacteria breeding inside the sensor 11 due to moisture, which helps to ensure the cleanliness of the water storage kettle 2 and prolong the storage time of the liquid in the water storage kettle 2. The first flexible wall 23 is arranged on the water storage kettle 2, and the first flexible wall 23 can be deformed when the air pressure in the induction cavity 213 changes. Thus, the deformation degree of the first flexible wall 23 can reflect the degree of change of the air pressure in the induction cavity 213, and further reflect the liquid level in the water storage cavity 212. When the first flexible wall 23 is deformed to a certain degree, the sensor 11 can be triggered to send information to the water supply system. Thus, automatic stopping of water supply to the water storage kettle 2 can be realized, and the probability of liquid overflow from the water storage kettle 2 due to excessive water supply can be reduced. In addition, the first flexible wall 23 can separate the sensor 11 and the induction cavity 213, that is, the first flexible wall 23 can isolate the water vapor in the water storage kettle 2 from the sensor 11, so that the sensor 11 can work in a relatively dry environment, which helps to prolong the service life of the sensor 11.

[0087] In some embodiments, the water storage mechanism further includes a base 1, which can be used to mount the water supply system. Referring to Figure 4 , the water storage kettle 2 and the base 1 can be detachably connected. When the user needs to take the liquid in the water storage kettle 2, the water storage kettle 2 can be removed from the base 1, and after pouring out the liquid, the water storage kettle 2 can be placed back into the base 1. In other embodiments, the water storage kettle 2 and the base 1 can be fixedly connected. At this time, the water storage kettle 2 can be provided with a water outlet, and the water outlet can be provided with a switch. When the user needs to take the liquid in the water storage kettle 2, the switch at the water outlet can be opened, so that the liquid can flow out of the water outlet. After taking, the switch is closed.

[0088] In some embodiments, the sensor 11 can be arranged on the base 1, so that the sensor 11 can not be in contact with the liquid in the water storage kettle 2, reducing the probability of liquid volatilization into the sensor 11, thereby reducing the possibility of bacterial growth in the sensor 11, and further reducing the possibility of damage to the sensor 11 due to moisture.

[0089] In some embodiments, the first flexible wall 23 is arranged spaced apart from the sensor 11, when the pressure in the induction cavity 213 increases, the first flexible wall 23 bulges towards the side of the sensor 11, the distance between the first flexible wall 23 and the sensor 11 becomes smaller, and the sensor 11 detects the change in pressure in the induction cavity 213 by detecting the distance between the sensor 11 and the first flexible wall 23. For example, when the liquid level in the water storage cavity 212 is below the maximum value, the first flexible wall 23 is located outside the detection range of the sensor 11, when the liquid level in the water storage cavity 212 reaches the maximum value, the first flexible wall 23 enters the detection range of the sensor 11, and the sensor 11 can perceive the first flexible wall 23. At this time, the sensor 11 can send information to the water supply system, so as to stop water injection.

[0090] In this embodiment, one cavity wall of the induction cavity 213 is the first flexible wall 23, the first flexible wall 23 is arranged spaced apart from the sensor 11 and towards the sensor 11, when the pressure in the induction cavity 213 increases, the first flexible wall 23 bulges from the center of the induction cavity 213 towards the sensor 11, and the sensor 11 detects the change in pressure in the induction cavity 213 by detecting the distance between the sensor 11 and the first flexible wall 23.

[0091] It should be noted that when the liquid level in the water storage cavity 212 rises, the liquid pressure in the water storage cavity 212 increases, at this time, the gas in the induction cavity 213 is subjected to greater compression, and the gas in the induction cavity 213 is pressurized due to compression, so that the first flexible wall 23 bulges from the center of the induction cavity 213 towards the sensor 11. Therefore, when the first flexible wall 23 bulges from the center of the induction cavity 213 towards the sensor 11, the degree of bulging of the first flexible wall 23 is related to the liquid level in the water storage cavity 212, and the higher the liquid level in the water storage cavity 212, the greater the degree of bulging of the first flexible wall 23.

[0092] As the liquid level in the water storage cavity 212 rises, the first flexible wall 23 can bulge outward from the center of the induction cavity 213, so that the degree of bulging of the first flexible wall 23 can reflect the liquid level in the water storage cavity 212, when the first flexible wall 23 bulges to a certain degree, the sensor 11 can be triggered to send information to the water supply system, so as to automatically stop water supply to the water storage kettle 2, thereby reducing the probability of liquid overflow from the water storage kettle 2 due to excessive water supply.

[0093] In some embodiments, the first flexible wall 23 is arranged at the top of the induction cavity 213 along the height direction of the water storage cavity 212, that is, the first flexible wall 23 is the top wall of the induction cavity 213, and the sensor 11 is arranged above the first flexible wall 23. In this way, the possibility of the first flexible wall 23 being submerged by the liquid in the water storage cavity 212 can be reduced, the influence of the liquid pressure in the water storage cavity 212 on the shape of the first flexible wall 23 can be reduced, and the detection accuracy can be improved.

[0094] With reference to Figure 3 The water storage kettle 2 further comprises an induction piece 25 arranged on the side of the first flexible wall 23 facing the sensor 11. The induction piece 25 is adapted to the sensor 11. When the induction piece 25 moves close to the sensor 11 and enters the detection range of the sensor 11, the induction piece 25 can trigger the sensor 11. When the first flexible wall 23 protrudes, the induction piece 25 can be pushed to move towards the sensor 11, so that the induction piece 25 moves close to and triggers the sensor 11.

[0095] In this embodiment, the water storage kettle 2 further comprises an induction piece 25 arranged on the first flexible wall 23 and outside the induction cavity 213. The induction piece 25 is adapted to the sensor 11. When the first flexible wall 23 protrudes and drives the induction piece 25 to move, the sensor 11 detects the distance between the sensor 11 and the first flexible wall 23 by sensing the induction piece 25.

[0096] In this embodiment, the water storage kettle 2 further comprises an induction piece 25 arranged on the first flexible wall 23 and outside the induction cavity 213. The induction piece 25 is adapted to the sensor 11. When the first flexible wall 23 protrudes and drives the induction piece 25 to move, the sensor 11 detects the distance between the sensor 11 and the first flexible wall 23 by sensing the induction piece 25.

[0097] In some other embodiments, the water storage kettle 2 can not be provided with the induction piece 25. The sensor 11 can be a distance sensor. In this case, the sensor 11 can detect the distance between the sensor 11 and the first flexible wall 23. When the distance between the sensor 11 and the first flexible wall 23 is less than a preset value, the sensor 11 can be triggered.

[0098] With reference to Figure 3In the embodiment, the sensing member 25 is a magnetic member, and the sensor 11 is a magnetic switch. By setting the sensing member 25 as a magnetic member and the sensor 11 as a magnetic switch, the sensing member 25 and the sensor 11 can be inducted by magnetism. For example, the peripheral portion of the sensing member 25 has a magnetic field. When the sensing member 25 moves towards the sensor 11, the distance between the sensing member 25 and the sensor 11 decreases. When the distance between the sensing member 25 and the sensor 11 decreases to a certain value, the sensor 11 enters the magnetic field range of the sensing member 25. At this time, the magnetic element in the sensor 11 is triggered by the magnetic field of the sensing member 25. That is, the sensor 11 can be triggered only when the sensor 11 enters the magnetic field range of the sensing member 25. In this way, the detection accuracy of the sensor 11 can be ensured.

[0099] For example, the magnetic member can be a magnet or an electromagnet, and the magnetic switch can be a reed switch or a Hall switch.

[0100] In other embodiments, the sensing member 25 can also be a component with an IC (Integrated Circuit Chip) chip. The sensor 11 can be an IC sensor compatible with the IC chip. When the first flexible wall 23 protrudes outward, the IC chip can be moved to approach the IC sensor and be recognized by the IC sensor. The IC sensor can be triggered after recognizing the IC chip, so that the base 1 stops supplying water to the water storage kettle 2. In other embodiments, the sensing member 25 can also be a component with an NFC (Near Field Communication) chip. The sensor 11 can be an NFC sensor compatible with the NFC chip. When the first flexible wall 23 protrudes outward, the NFC chip can be moved to approach the NFC sensor and be recognized by the NFC sensor. The NFC sensor can be triggered after recognizing the NFC chip, so that the base 1 stops supplying water to the water storage kettle 2.

[0101] Continuing to refer to Figure 3 In the embodiment, the middle portion of the first flexible wall 23 is connected with the sensing member 25, and the thickness of the middle portion of the first flexible wall 23 is greater than the thickness of the edge portion of the first flexible wall 23.

[0102] It should be noted that the middle portion of the first flexible wall 23 is the central portion of the first flexible wall 23, and the edge portion of the first flexible wall 23 is the edge portion of the first flexible wall 23. The edge portion of the first flexible wall 23 surrounds the central portion of the first flexible wall 23, that is, the edge portion of the first flexible wall 23 surrounds the middle portion of the first flexible wall 23.

[0103] The thickness of the middle part of the first flexible wall 23 is greater than the thickness of the edge part of the first flexible wall 23, which can increase the thickness of the connecting part of the first flexible wall 23 and the inductive element 25, thereby enhancing the strength of this area and improving the connection stability of the first flexible wall 23 and the inductive element 25. In addition, the thickness of the edge part of the first flexible wall 23 is small, and the strength of this area is low. When the pressure in the inductive cavity 213 increases, the edge part of the first flexible wall 23 can be deformed, so that the first flexible wall 23 can protrude outward from the center of the inductive cavity 213, thereby driving the inductive element 25 to move to trigger the sensor 11.

[0104] With reference to Figure 5 and Figure 6 In some embodiments, the first flexible wall 23 is provided with a first stepped surface 231 and a groove 232. The first stepped surface 231 is annular, and the first stepped surface 231 is arranged on the side of the first flexible wall 23 facing the inductive element 25. The groove 232 is arranged on the side of the first flexible wall 23 away from the inductive element 25. The first stepped surface 231 arranged on the first flexible wall 23 can facilitate the judgment of the thickness of each area of the first flexible wall 23 through the shape of the first flexible wall 23, thereby facilitating the installation of the inductive element 25 on the first flexible wall 23. The groove 232 arranged on the first flexible wall 23 can reduce the local thickness of the first flexible wall 23, thereby improving the flexibility and elasticity of the first flexible wall 23. In addition, the arrangement of the first stepped surface 231 and the groove 232 can make the cross section of the first flexible wall 23 present a stepped shape, which can help to increase the overall strength of the first flexible wall 23, thereby helping to improve the supporting capacity of the first flexible wall 23 for the inductive element 25.

[0105] With reference to Figure 3 The water storage kettle 2 further comprises a connecting element 24, and the two ends of the connecting element 24 are respectively connected with the inductive element 25 and the first flexible wall 23, that is, the inductive element 25 is connected with the first flexible wall 23 through the connecting element 24. By arranging the connecting element 24, the connecting element 24 can assist in fixing the inductive element 25 to the first flexible wall 23, so as to reduce the connection difficulty between the inductive element 25 and the first flexible wall 23.

[0106] With reference to Figure 3 , Figure 5 and Figure 6 In some embodiments, the first flexible wall 23 is provided with a protruding part 233, and the connecting element 24 is provided with a mounting groove 241 matched with the protruding part 233. The protruding part 233 is inserted into the mounting groove 241 to connect the first flexible wall 23 and the connecting element 24. By arranging the protruding part 233 on the first flexible wall 23 and the mounting groove 241 on the connecting element 24, and inserting the protruding part 233 into the mounting groove 241, the first flexible wall 23 can be connected with the connecting element 24 through plug-in connection, which can also help to stably connect the connecting element 24 and the first flexible wall 23.

[0107] In some embodiments, the protrusion 233 and the mounting groove 241 can be in an interference fit, that is, the size of the protrusion 233 can be slightly larger than the size of the mounting groove 241. After the protrusion 233 is inserted into the mounting groove 241, the outer periphery of the protrusion 233 will be extruded with the side wall of the mounting groove 241, thereby generating a large friction force between the two, thereby achieving stable connection of the two; in other embodiments, the protrusion 233 and the mounting groove 241 can be in a clearance fit or a transition fit, that is, the size of the protrusion 233 can be smaller than or equal to the size of the mounting groove 241. At this time, glue can be used to assist assembly. For example, glue can be filled between the outer periphery of the protrusion 233 and the side wall of the mounting groove 241. After the glue is cured, stable connection of the first flexible wall 23 and the connecting piece 24 can be achieved.

[0108] In some embodiments, the connecting piece 24 can be tubular. Thus, the mounting groove 241 penetrates the end of the connecting piece 24 along the length direction of the connecting piece 24. In other embodiments, the connecting piece 24 can be a spiral spring. At this time, the empty area in the middle of the spiral spring is the mounting groove 241 of the connecting piece 24.

[0109] Referring to Figure 2 In some embodiments, the bottom of the induction cavity 213 is in communication with the water storage cavity 212. For example, the bottom of the induction cavity 213 is provided with a first opening 214. The induction cavity 213 is in communication with the water storage cavity 212 through the first opening 214. The liquid in the water storage cavity 212 can flow into the induction cavity 213 through the first opening 214. When the liquid level in the induction cavity 213 rises above the first opening 214, the first opening 214 is blocked by the liquid. At this time, the induction cavity 213 is equivalent to a sealed chamber. The gas in the induction cavity 213 is sealed in the induction cavity 213. When the liquid level in the water storage cavity 212 rises, the liquid in the water storage cavity 212 continuously flows into the induction cavity 213, causing the liquid level in the induction cavity 213 to rise, thereby increasing the air pressure in the induction cavity 213, causing the first flexible wall 23 to protrude outward.

[0110] It should be noted that when the base 1 replenishes water to the water storage cavity 212 through the water inlet 222, the liquid in the water storage cavity 212 can enter the induction cavity 213 through the first opening 214, and as the liquid level continues to rise, the first opening 214 is gradually submerged by the liquid. Thus, part of the gas is sealed in the induction cavity 213. When the base 1 continues to replenish water to the water storage cavity 212, the liquid continuously enters the induction cavity 213 from the first opening 214, causing the liquid level in the induction cavity 213 to gradually rise, the space for accommodating gas in the induction cavity 213 gradually decreases, and the air pressure in the induction cavity 213 continuously increases. Thus, a pressure difference is generated between the two sides of the first flexible wall 23, causing the first flexible wall 23 to protrude outward from the center of the induction cavity 213.

[0111] It should be noted that when the base 1 continues to supply water to the water storage cavity 212, and as the liquid level continues to rise, the first opening 214 is gradually submerged by the liquid, and a portion of the gas is sealed in the induction cavity 213. In the subsequent stage, the gas sealed in the induction cavity 213 blocks the rise of the liquid level in the induction cavity 213, so that the liquid level in the induction cavity 213 is always lower than that of the water storage cavity 212. The first flexible wall 23 can be arranged at the top of the induction cavity 213 or at a position adjacent to the top on the side. In this way, the liquid in the induction cavity 213 can not submerge the first flexible wall 23.

[0112] The first opening 214 is arranged at the bottom of the induction cavity 213 and is in communication with the water storage cavity 212. When there is no water or a small amount of water in the water storage cavity 212, the gas in the induction cavity 213 can enter the water storage cavity 212 through the first opening 214 and can enter the external environment through the water inlet 222 of the water storage cavity 212, that is, the induction cavity 213 is in communication with the external environment. The gas in the induction cavity 213 can flow to the external environment, and fresh air in the external environment can also enter the induction cavity 213. In this way, the possibility of bacteria breeding in the induction cavity 213 can be reduced.

[0113] Referring to Figure 3 , Figure 7 and Figure 8 , the water storage kettle 2 further comprises an induction assembly and a partition plate 211. The induction assembly comprises a protective cover 26 and a first flexible wall 23. The protective cover 26 is provided with a protective cavity 261, and the first flexible wall 23 is arranged in the protective cavity 261 and is in sealing connection with the inner wall of the protective cavity 261. The partition plate 211 is arranged in the inner cavity of the water storage kettle 2. The protective cover 26 is in sealing connection with the partition plate 211. The protective cover 26, the first flexible wall 23 and the partition plate 211 form an induction cavity 213. By arranging the protective cover 26 and arranging the first flexible wall in the protective cavity 261 of the protective cover 26, the protective cover 26 can protect the first flexible wall 23, so that the first flexible wall 23 can be spaced from the external environment, that is, the first flexible wall 23 can not be exposed to the external environment. In this way, the influence of the external environment on the deformation of the first flexible wall 23 can be reduced, which helps to improve the detection accuracy of the sensor 11. In addition, the protective cover 26 is in sealing connection with the partition plate 211, that is, the first flexible wall 23 is indirectly connected with the partition plate 211 through the protective cover 26. When the first flexible wall 23 needs to be replaced, the protective cover 26 can be removed from the partition plate 211. In this way, the maintenance difficulty of the water storage kettle 2 can be reduced.

[0114] In some embodiments, the induction assembly further comprises an induction piece 25 arranged on the first flexible wall 23. The arrangement of the protective cover 26 can also integrate the induction assembly as a whole, which facilitates the replacement of the induction assembly as a whole when the water storage kettle 2 is maintained.

[0115] In some embodiments, the protective cavity 261 is also used to guide the movement of the sensing member 25. The length of the protective cavity 261 extends along the direction of movement of the sensing member 25, and the outer periphery of the sensing member 25 abuts against the wall of the protective cavity 261. By providing the protective cavity 261 to guide the movement of the sensing member 25, the deviation of the movement of the sensing member 25 can be reduced. When the liquid level in the water storage chamber 212 rises to a preset height, the sensing member 25 can promptly trigger the sensor 11, causing the water supply assembly to stop replenishing water to the water storage chamber 212. In addition, the protective cover 26 can simultaneously provide protection and guidance, thereby helping to reduce the number of components within the water storage mechanism and simplify the structure of the water storage mechanism.

[0116] Reference Figure 2 In some embodiments, the bottom of the partition 211 is separated from the cavity wall of the water storage pot 2 to form a first opening 214. In this way, there is no need to set a hole structure on the partition 211, which can reduce the processing difficulty of the partition 211.

[0117] In other embodiments, a hole structure may be provided on the partition 211 to form a first opening 214 communicating with the sensing chamber 213 and the water storage chamber 212 . In this way, the height of the first opening 214 may be easily adjusted.

[0118] Reference Figure 3 and Figure 8 In some embodiments, the water storage pot 2 further includes a protective cover 26, which can be connected to the top of the partition 211. A second step surface 262 is provided in the protective cover 26, and the edge of the first flexible wall 23 can be connected to the second step surface 262. At this time, the first flexible wall 23, the partition 211, the cavity wall of the water storage pot 2 and a portion of the protective cover 26 together enclose a sensing cavity 213; in other embodiments, the first flexible wall 23 can be directly connected to the top of the partition 211. At this time, the sensing cavity 213 is formed by the first flexible wall 23, the partition 211 and the cavity wall of the water storage pot 2.

[0119] Reference Figure 10 In other embodiments, the sensing chamber 213 is a sealed chamber provided on the side of the water storage chamber 212. The sensing chamber 213 and the water storage chamber 212 have a common cavity wall, and the common cavity wall is a second flexible wall 27. The second flexible wall 27 can be deformed by the liquid in the water storage chamber 212, and when the second flexible wall 27 is deformed, it can squeeze the sensing chamber 213, thereby increasing the pressure in the sensing chamber 213. Figure 10 (a) in the figure, at this time, there is no water in the water storage chamber 212, refer to Figure 10(b) in the first flexible wall 23, at this time, the water in the water storage cavity 212 can press the second flexible wall 27, and as the liquid level in the water storage cavity 212 rises, the pressing effect of the water in the water storage cavity 212 on the second flexible wall 27 becomes more obvious, the second flexible wall 27 bulges towards the center of the induction cavity 213, so that the pressure inside the induction cavity 213 becomes larger.

[0120] It should be noted that the second flexible wall 27 is a solid component with a certain thickness, which can be made of a flexible or elastic film material, or made of a flexible or elastic plate material; in some embodiments, the second flexible wall 27 can have elasticity, and when the liquid level in the water storage cavity 212 rises, the second flexible wall 27 deforms elastically under the action of the liquid pressure in the water storage cavity 212, so that the second flexible wall 27 can bulge towards the center of the induction cavity 213; in other embodiments, the second flexible wall 27 can not have elasticity, and the area of the second flexible wall 27 can be increased and formed into wrinkles, and when the liquid level in the water storage cavity 212 rises, the wrinkles of the second flexible wall 27 are stretched under the action of the liquid pressure in the water storage cavity 212, and the second flexible wall 27 relaxes and bulges towards the center of the induction cavity 213.

[0121] It should be noted that the width of the induction cavity 213 can be much smaller than the width of the water storage cavity 212, and the length of the induction cavity 213 can be equal to or slightly smaller than the length of the water storage cavity 212, so that the induction cavity 213 can have an elongated structure, and when the liquid level in the water storage cavity 212 changes, the air pressure in the induction cavity 213 can change accordingly.

[0122] It can be understood that the volume of the induction cavity 213 is small, and compared with the water storage cavity 212, the induction cavity 213 is difficult to clean, and the induction cavity 213 is set as a sealed cavity, so that the possibility of the liquid in the water storage cavity 212 and other impurities entering the induction cavity 213 can be reduced, thereby reducing the cleaning dead angle of the water storage kettle 2 and the cleaning difficulty of the water storage kettle 2; the second flexible wall 27 is provided, and the change of the liquid pressure in the water storage cavity 212 can be transmitted to the induction cavity 213 through the deformation of the second flexible wall 27, so that the pressure in the induction cavity 213 changes accordingly, so that the pressure in the induction cavity 213 can be detected by the sensor 11 to automatically stop water replenishment.

[0123] Continuing to refer to Figure 10 , in some embodiments, the first flexible wall 23 of the induction cavity 213 can be connected with the second flexible wall 27, and the second flexible wall 27 and the first flexible wall 23 can be integrally formed or adhesively connected.

[0124] Referring to Figure 7 , Figure 9 and Figure 11In the embodiment, the water storage kettle 2 further comprises a kettle body 21 and a kettle cover 22, the baffle 211 and the first flexible wall 23 are arranged on the kettle body 21, the kettle body 21 is further provided with a second opening 215 which is in communication with the water storage cavity 212, the kettle cover 22 is used for covering the second opening 215, the water inlet 222 is arranged on the kettle cover 22, and the notch 221 is further arranged on the kettle cover 22, the notch 221 can be used for avoiding the protective cover 26, so as to reduce the minimum distance between the inductive piece 25 and the sensor 11, so that the inductive piece 25 can timely trigger the sensor 11.

[0125] In some embodiments, the water storage kettle 2 is detachably connected with the base 1, and the kettle body 21 of the water storage kettle 2 can be provided with a handle 216, so that the water storage kettle 2 can be conveniently taken.

[0126] The application further provides a refrigerator comprising a water supply system (not shown in the figure) and the water storage mechanism in any of the above embodiments, and the water inlet 222 of the water storage mechanism is connected with the water supply system. Since the sensor 11 of the water storage mechanism in any of the above embodiments is arranged outside the water storage cavity 212 and the inductive cavity 213, the possibility of liquid pollution of the sensor 11 can be reduced, so that the shelf life of the liquid stored in the refrigerator can be prolonged, in addition, the sensor 11 can be used in a relatively dry environment, and the possibility of damage of the sensor 11 caused by moisture entering the inside of the sensor 11 is low, so that the service life of the sensor 11 can be prolonged, which is helpful to improve the quality of the refrigerator and reduce the maintenance frequency of the refrigerator.

[0127] In the embodiment, the water supply system can be arranged on the base 1 of the water storage mechanism, the water supply system can comprise a water pipe, one end of the water pipe is in communication with an external pipeline, the other end of the water pipe is in communication with the water inlet 222 of the water storage cavity 212, and an electric valve can be arranged on the water pipe, the electric valve can be connected with a control panel of the refrigerator, and a user can open or close the electric valve through the control panel.

[0128] The above merely provides the preferred embodiments of the application, but should not be used to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
