[0038] According to the embodiment of the present application, please refer to Figures 1-5 A refrigerator dispenser 100 is provided, which comprises a dispenser body 110, the dispenser body 110 is provided with a material outlet, the material outlet is used for discharging material to a receiving member, the dispenser body 110 comprises a seat member 10, a limit switch 50 and a lifting assembly 30. Wherein, the limit switch 50 is arranged on the seat member 10. The lifting assembly 30 is located on one side of the limit switch 50, the lifting assembly 30 is slidingly connected with the seat member 10 along a vertical direction Z, the lifting assembly 30 is used for blocking splashing in the material discharging process, the lifting assembly 30 has a limit state of triggering the limit switch 50 and an unlocking state of releasing the limit switch 50. The limit switch 50 is arranged to stop the movement of the lifting assembly 30 when triggered.

[0039] The vertical direction Z refers to the reference direction of the refrigerator dispenser 100 in the working or normal placing state.

[0040] The seat member 10 can be an integral piece formed by one piece or multiple pieces connected with each other.

[0041] The material outlet can be an ice outlet 12, also can be a water outlet 311, also can be the ice outlet 12 and the water outlet 311.

[0042] The receiving member is a water receiving container, also can be an ice receiving tray, which can be determined according to the user's demand.

[0043] The limit switch 50 can be a travel switch or a micro switch.

[0044] The number of limit switches 50 can be one, also can be two or more. For example, the number of limit switches 50 is two, the limit switches 50 are arranged at the limit positions of the upward and downward movement of the lifting assembly 30, and the limit switches 50 can be triggered when the lifting assembly 30 moves to the limit position.

[0045] According to the refrigerator dispenser 100, the setting of the limit switch 50 enables the lifting assembly 30 to move up and down within a set stroke, so as to reduce the probability of damage caused by overstroke movement of the lifting assembly 30 and improve the reliability of the refrigerator dispenser 100.

[0046] In some embodiments of the present application, please refer to Figures 3-5 , the lifting assembly 30 is configured to have a first limit position and a second limit position at which the limit switch 50 is triggered, and the lifting assembly 30 is further configured to have an intermediate position at which the limit switch 50 is released, the intermediate position being located between the first limit position and the second limit position, the first limit position and the second limit position being spaced apart along the vertical direction Z, and the first limit position being located above the second limit position. The refrigerator dispenser 100 further comprises a limit trigger 80 located on one side of the lifting assembly 30 along a first direction X, the first direction X intersecting the vertical direction Z, the limit trigger 80 being movably connected to the seat member 10, and the lifting assembly 30 being capable of driving the limit trigger 80 to trigger the limit switch 50 when the lifting assembly 30 is located at the first limit position or the second limit position.

[0047] The movable connection can be a sliding connection or a rotating connection.

[0048] As an example, the limit trigger 80 is slidingly connected to the seat member 10, the limit trigger 80 being located between the limit switch 50 and the lifting assembly 30, the limit trigger 80 being elastically connected to the seat member 10 by a compression spring, the elastic force of the compression spring having a tendency to move the limit trigger 80 away from the limit switch 50 and towards the lifting assembly 30. The surface of the limit trigger 80 facing the lifting assembly 30 is provided with a partial spherical surface, which enables the limit trigger 80 to move towards the limit switch 50 during the up-and-down movement of the lifting assembly 30, so as to trigger the limit switch 50.

[0049] In this way, the limit trigger 80 at two different positions of the lifting assembly 30 can trigger the limit switch 50, achieving limiting during the movement of the lifting assembly 30, so as to reduce the number of limit switches 50 and reduce costs.

[0050] In some embodiments of the present application, the movable connection is a rotating connection, the axis of rotation of the limit trigger 80 relative to the seat member 10 intersecting the vertical direction Z and the first direction X, respectively, the limit switch 50 being a limit microswitch, the limit microswitch having a spring piece 51 abutting against the limit trigger 80, the elastic force of the spring piece 51 having a tendency to block the limit trigger 80 from triggering the limit microswitch.

[0051] The movable connection is limited to a rotating connection, so that the limit trigger 80 can act in a rotating manner when it is driven by the lifting assembly 30 to trigger the limit microswitch. Compared with other forms of movable connection, the rotating connection has the characteristics of smoother action and smaller resistance, which makes the triggering process more smooth and reduces the occurrence of jamming or unevenness, so that the entire triggering mechanism can operate more stably and reliably, ensuring that the limit trigger 80 can accurately and timely trigger every time the lifting assembly 30 reaches the corresponding limit position.

[0052] In some embodiments of the present application, please refer to Figures 3-5 The lifting assembly 30 is provided with a limit slot 322 on one side of the limit trigger 80, and part of the limit trigger 80 is arranged in the limit slot 322. The limit slot 322 includes a first wall surface 3221 and a second wall surface 3222, which are arranged in a vertical direction Z and the first wall surface 3221 is located above the second wall surface 3222. When the lifting assembly 30 is in the first limit position, the second wall surface 3222 drives the limit trigger 80 to trigger the limit switch 50. When the lifting assembly 30 is in the second limit position, the first wall surface 3221 drives the limit trigger 80 to trigger the limit switch 50. When the first wall surface 3221 is separated from the limit trigger 80 or the second wall surface 3222 is separated from the limit trigger 80, the triggering of the limit switch 50 is released.

[0053] The limit slot 322 can be, but is not limited to, a trapezoidal slot, a rectangular slot or other special-shaped slots.

[0054] As an example, the number of limit microswitches is two, and the two limit microswitches are arranged in a vertical direction Z. The number of limit triggers 80 is two, and the two limit triggers 80 are arranged in a vertical direction Z. For convenience of description, the uppermost limit microswitch is the first microswitch, the lowermost limit microswitch is the second microswitch, the uppermost limit trigger 80 is the first trigger, and the lowermost limit trigger 80 is the second trigger. When the lifting assembly 30 moves upward, the second wall surface 3222 abuts against the second trigger and rotates the second trigger to trigger the second microswitch against the elastic force of the elastic sheet 51 of the second microswitch. When the lifting assembly 30 moves downward, the first wall surface 3221 abuts against the first trigger and rotates the first trigger to trigger the first microswitch against the elastic force of the elastic sheet 51 of the first microswitch.

[0055] In this way, the limit trigger 80 can move in the limit slot 322, and when the lifting assembly 30 moves to the two limit positions, the slot wall of the limit slot 322 is used to trigger the limit trigger 80 to rotate to trigger the limit switch 50.

[0056] In some embodiments of the present application, please refer toFigure 5 The distance between the vertical plane P and the second wall surface 3222 is in a decreasing trend along the direction from the first wall surface 3221 to the second wall surface 3222.

[0057] The distance between the vertical plane P and the second wall surface 3222 is H, and H is in a decreasing trend.

[0058] Thus, when the second wall surface 3222 abuts against the limiting trigger 80, the second wall surface 3222 slides relative to the limiting trigger 80, and the second wall surface 3222 has a guiding effect, so that the limiting trigger 80 can rotate to a predetermined position to trigger the limiting switch 50, and the probability of jamming during triggering can be reduced, and the reliability of work can be improved.

[0059] In some embodiments of the present application, please refer to Figure 4 The refrigerator dispenser 100 further comprises a driving mechanism 40, and the lifting assembly 30 comprises a splash-proof cylinder 31 and a driven part 32. The driven part 32 is connected with the splash-proof cylinder 31, and the splash-proof cylinder 31 is used to block splashing during material discharge. The driven part 32 is connected with the seat member 10 in the vertical direction Z, and the driven part 32 is in transmission connection with the driving mechanism 40. The driving mechanism 40 is used to drive the driven part 32 to move in the vertical direction Z, and the limiting switch 50 is arranged to be triggered to stop the driving mechanism 40 from driving the driven part 32.

[0060] The splash-proof cylinder 31 can be fixed with the driven part 32 by screw connection, riveting, welding, clamping or one-piece forming.

[0061] The driving mechanism 40 and the driven part 32 can be in driving connection by electric driving.

[0062] The driving mechanism 40 can be a component composed of a motor and a transmission mechanism. For example, the driving mechanism 40 can be an electric push rod, and the driving mechanism 40 can also be a component composed of a motor and a gear 41. The splash-proof cylinder 31 is installed with a rack, the gear 41 is in meshing with the rack, the gear 41 is driven to rotate by electricity, and the movement of the splash-proof cylinder 31 is realized. A speed reduction component such as a speed reducer or a synchronous belt transmission component can be arranged between the motor and the gear 41 to realize speed reduction.

[0063] When the limit switch 50 is a signal switch (such as a limit micro-motion switch), after the limit switch 50 is triggered to generate a limit signal, the controller of the refrigerator receives the signal and can stop the driving mechanism 40 from working, so as to stop the lifting assembly 30 from moving. When the limit switch 50 is a mechanical limit switch, during the movement of the lifting assembly 30, the limit switch 50 is in a normally closed state, and after the limit switch 50 is triggered, the driving mechanism 40 driving the lifting assembly 30 is automatically powered off, that is, the driving mechanism 40 driving the lifting assembly 30 is in series with the limit switch 50 and the power supply.

[0064] During the automatic water and / or ice taking process, the anti-splashing cylinder 31 of the lifting assembly 30 can move from the first limit position to the second limit position, and after the limit switch 50 is triggered, the lifting assembly 30 stops moving, so as to reduce splashing during water and / or ice taking. When manual water and / or ice taking is needed, the lifting assembly 30 can move to the second limit position according to the received instruction, and manual water and / or ice taking is performed.

[0065] In some embodiments of the present application, please refer to Figure 4 The driving mechanism 40 further comprises a driving member 42 and a gear 41, the gear 41 is rotationally connected with the seat body 10, the driven member 32 is provided with engagement teeth 321 arranged at intervals along the vertical direction Z, the engagement teeth 321 are engaged with the gear 41, the driving member 42 is in transmission connection with the gear 41, and the driving member 42 is used to drive the gear 41 to rotate.

[0066] Since the plurality of engagement teeth 321 of the driven member 32 are arranged at intervals along the vertical direction Z and are in transmission connection with the gear 41, this transmission mode can ensure the accuracy of power transmission. When the gear 41 rotates relative to the seat body under the driving of the driving member 42, the gear 41 can accurately and stably drive the anti-splashing member to move to the corresponding position through the cooperation of the gear 41 and the engagement teeth 321, so as to be able to trigger the micro-motion switch by operating the trigger member.

[0067] In some embodiments of the present application, please refer to Figures 1-3 The material outlet comprises an ice outlet 12, and the top of the seat body 10 is provided with the ice outlet 12; and / or the material outlet comprises a water outlet 311, and the refrigerator dispenser 100 further comprises a water supply pipe 70, part of the water supply pipe 70 is arranged on the lifting assembly 30, the lifting assembly 30 is provided with the water outlet 311, and the water outlet end of the water supply pipe 70 is in communication with the water outlet 311.

[0068] The ice outlet 12 can be in communication with an ice storage box of the refrigerator through an ice discharge valve; and / or the water supply pipe 70 is in communication with a water source, and the water supply pipe 70 is provided with a water supply valve.

[0069] When ice is taken, the user can press the automatic ice taking key on the control panel of the refrigerator, and the controller of the refrigerator receives the ice taking instruction, controls the anti-splashing cylinder 31 to move to the upper side of the receiving member, and opens the ice discharge valve to automatically discharge ice.

[0070] The refrigerator can be used to make cold water and / or ice cubes, and the water and / or ice can be taken from the ice discharge port 12 and / or the water discharge port 311, so as to facilitate the user to make cold drinks or frozen food, and improve the applicability of the refrigerator.

[0071] In some embodiments of the present application, please refer to Figures 1-3 The dispenser body 110 further comprises a material taking trigger 20 and a material taking micro switch 60. The material taking trigger 20 is movably connected with the seat member 10, and the material taking micro switch 60 is arranged on the seat member 10. The material taking trigger 20 has a first state of triggering the material taking micro switch 60 and a second state of releasing the micro switch. The material taking micro switch 60 is arranged to discharge material from the material outlet to the receiving member when triggered.

[0072] The material taking trigger 20 and the seat member 10 can be connected by sliding or rotating.

[0073] The material taking micro switch 60 can be fixed to the seat member 10 by screwing, bonding or clamping.

[0074] For example, the seat member 10 is provided with an opening, the material taking trigger 20 is arranged in the opening and elastically connected with the seat member 10 by a spring, so that the trigger forms a structure similar to a "button". By pressing the material taking trigger 20, the material taking trigger 20 is in contact with or separated from the material taking micro switch 60, so as to realize the functions of triggering and releasing the material taking micro switch 60.

[0075] For example, the material taking trigger 20 is rotatably connected with the seat member 10. The seat member 10 is provided with an embedding structure, which can be a limiting hole or a limiting groove 322. The material taking trigger 20 is provided with a limiting structure, at least part of which is located in the embedding structure and can rotate in the embedding structure around the axis of rotation of the trigger relative to the seat member 10. An elastic member, which can be a compression spring or a spring sheet 51, is arranged between the material taking trigger 20 and the seat member 10. The elastic force of the compression spring has a tendency to move the material taking trigger 20 away from the material taking micro switch 60.

[0076] For example, the above-mentioned anti-splashing cylinder 31 can move to the upper side of the material taking trigger 20, so that the material taking trigger 20 is not blocked by the anti-splashing cylinder 31 when manually triggered, thereby facilitating the operation of manually taking water and / or ice.

[0077] Therefore, the user can manually touch the material taking trigger 20 according to his own needs to realize manual ice taking and / or water taking, thereby improving the flexibility of the refrigerator dispenser 100.

[0078] According to the embodiment of the present application, a refrigerator is provided, which comprises the refrigerator dispenser 100 of the above embodiment.

[0079] Since the refrigerator dispenser 100 comprises all the technical features of the refrigerator, the effects are the same as above, and will not be repeated here.

The refrigerator is provided with an ice storage box, and the bottom of the ice storage box is communicated with the ice outlet 12 at the top of the seat body member 10 through an ice discharge valve. When the controller of the refrigerator receives an ice and / or water taking instruction, the controller controls the lifting assembly 30 to move to a predetermined position, and then controls the corresponding valve to automatically discharge ice and / or water. Users can also choose to manually take ice and / or water, and manually take ice and / or water by triggering the microswitch through manual operation of the material taking trigger 20.

[0081] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
