Description

[0003] In the related art, the common water supply methods are: (1) direct water supply from tap water. In this way, it is often necessary to add structures such as electromagnetic valves, there is a risk of water leakage, and it takes a long time for the temperature of tap water to drop to the freezing point; (2) using a split magnetic pump structure for water supply. The split magnetic pump consists of a water pump assembly and a motor assembly. The water pump assembly is internally provided with a first permanent magnet, and the motor assembly is internally provided with a second permanent magnet. During operation, the motor drives the second permanent magnet to rotate, thereby driving the first permanent magnet to rotate to complete the water pumping action. This solution can achieve the effect of separating water and electricity and discharging water in the refrigerating chamber in advance. However, after the second permanent magnet rotates, the first permanent magnet starts to rotate only under the magnetic force of the second permanent magnet. Affected by the wall thickness of the water storage box and the magnetic force transmission effect between the two permanent magnets, there will be a certain time difference in the rotation of the two permanent magnets, that is, the rotation is asynchronous, resulting in water supply delay.

In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0082] Figure 1 and Figure 2 are schematic structural diagrams of some embodiments of the refrigerator of the present application; referring to Figure 1 and Figure 2 , the refrigerator 1 has an approximately cuboid shape, and the appearance of the refrigerator 1 is defined by a box body 100 for defining an internal storage space and a plurality of door bodies 200 for opening or closing the box body 100.

[0083] Wherein, referring to Figure 2 , the door body 200 includes a door body outer shell 210 located outside the box body 100, a door body inner liner 220 located inside the box body 100, an upper end cover 230, a lower end cover 240, and a heat insulation layer (not shown) located between the door body outer shell 210, the door body inner liner 220, the upper end cover 230, and the lower end cover 240; generally, the heat insulation layer is filled with foaming material.

[0084] The box body 100 includes a box shell and an inner liner. The inner liner is disposed inside the box shell, and an installation space is formed therebetween for installing other component structures of the refrigerator and forming a foaming heat insulation layer. The inside of the inner liner is vertically partitioned into a lower freezer compartment 100A and an upper refrigerating compartment 100B. Each of the separated spaces may have an independent storage space.

[0085] Specifically, the freezer compartment 100A is defined at the lower side of the cabinet 100 and can be selectively covered by a drawer-type freezer door body 200A. The space above the freezer compartment 100A is partitioned into a left side and a right side to respectively define the refrigerator compartments 100B.

[0086] The refrigerator compartment 100B can be selectively opened or closed by a refrigerator compartment door body 200B pivotally mounted on the refrigerator compartment 100B.

[0087] Referring Figures 3 to 13 , the refrigerator in some embodiments of the present application further includes a water-using component (not shown) and a water supply system 300.

[0088] The water-using component can be at least one of a humidification module, an ice-making module, and a drinking water module. The number of settings is not limited and can be selected according to actual usage requirements. The functions of the water-using component can be replaced according to the functional requirements of the refrigerator to meet the usage requirements of the refrigerator.

[0089] The water supply system 300 is used to supply water to the water-using component.

[0090] For a refrigerator carrying a water-using component, it is necessary to be able to supply water to the ice maker or the water dispenser safely and effectively.

[0091] In some embodiments of the present application, the water supply system 300 includes a water storage component 310. As a water storage container, it is provided in the cabinet 100 of the refrigerator. The water storage component 310 can be provided in the cabinet 100 by a detachable structure such as a draw structure or a snap structure, so as to be detached from the cabinet 100 of the refrigerator for operations such as adding water or cleaning.

[0092] In some embodiments of the present application, the water storage component 310 is provided on the storage board of the refrigerator compartment 100B.

[0093] In some embodiments of the present application, the water supply system 300 includes a water pumping assembly 320. As the power assembly of the water supply system 300, it provides water pumping power.

[0094] The water pumping assembly 320 includes a housing 321. A sealing portion 322 is formed on the housing 321, and a water inlet 323 and a water outlet 324 are provided outside the sealing portion 322. The water inlet 323 is communicated with the water storage space of the water storage component 310.

[0095] The water pumping assembly 320 includes a water supply pipe (not shown). One end of the water supply pipe is communicated with the water outlet 324, and the other end is communicated with the water-using component.

[0096] The water pumping assembly 320 includes a power supply (not shown). The power supply is provided outside the water storage component 310 to be separated from the water in the water storage component 310 and is convenient for external power connection. The power supply is used to output an alternating current to the transmitting coil 326.

[0097] The water pumping assembly 320 includes a transmitting coil 326 which is arranged outside the water storage component 310 to be separated from the water in the water storage component 310 and is convenient for connecting to a power supply. The transmitting coil 326 is used to generate an alternating magnetic field.

[0098] The water pumping assembly 320 includes a receiving coil 327 which is arranged in the sealing part 322 to be separated from the water in the water storage component 310. The receiving coil 327 is placed corresponding to the transmitting coil 326, and the two can be arranged in parallel, and is used to generate an alternating current in the alternating magnetic field.

[0099] The water pumping assembly 320 includes an exciting coil 328 which is arranged in the sealing part 322 to be separated from the water in the water storage component 310. The exciting coil 328 uses the alternating current generated by the receiving coil 327 to generate an alternating magnetic field.

[0100] The water pumping assembly 320 includes a permanent magnet 329 which is arranged on the housing 321 and is located outside the sealing part 322, and performs a rotational movement under the action of the alternating magnetic field generated by the exciting coil 328.

[0101] The water pumping assembly 320 includes an impeller 325 which is located outside the sealing part 322 and is coaxially connected to the permanent magnet 329, and is driven by the permanent magnet 329 to rotate, so as to drive the water in the water storage component 310 to flow into the water inlet 323, and is output via the water outlet 324 and the water supply pipe to supply water to the water using component.

[0102] In the refrigerator according to some embodiments of the present application, the transmitting coil 326 of the water supply system 300 is located outside the water storage component 310, and the receiving coil 327 and the exciting coil 328 are arranged in the sealing part 322 on the housing 321 of the water pumping assembly 320 in the water storage component 310. Electromagnetic conversion is completed through the electromagnetic interaction between the transmitting coil 326 and the receiving coil 327, and the exciting coil 328 generates an alternating magnetic field with the alternating current generated by the receiving coil 327, so that the permanent magnet 329 performs a rotational movement under the action of the alternating magnetic field generated by the exciting coil 328, and then drives the impeller 325 to rotate, so as to drive the water in the water storage component 310 to flow into the water inlet 323, and is output via the water outlet 324 and the water supply pipe to pump water to the water supply component, achieving the purpose of separating water and electricity, with high safety and no risk of water leakage.

[0103] Finally, the impeller 325 is driven to rotate through electromagnetic conversion. Compared with the related art in which a split magnetic pump is used to supply water in a manner of magnetic generation of magnetism, the water supply control is accurate and the response is rapid, and the situation of water supply delay can be effectively avoided.

[0104] In addition, the water supply system 300 has a simple structure. The water pumping assembly 320 is not limited to the water pump models produced by existing water pump manufacturers and can be assembled independently. The parameters of relevant components can be set according to the actual required water supply volume, which is conducive to realizing independent control of the water supply volume.

[0105] Specifically, the power supply outputs an alternating current to the transmitting coil 326. After the alternating current passes through the transmitting coil 326, according to Faraday's law of electromagnetic induction, an alternating magnetic field is generated in the transmitting coil 326. At this time, the receiving coil 327 arranged in parallel with the transmitting coil 326 moves in the alternating magnetic field generated by the transmitting coil 326 to cut the magnetic induction lines, thereby generating an alternating current. The alternating current is output to the exciting coil 328, and the exciting coil 328 generates an alternating magnetic field. Due to the repulsion of like poles, the alternating magnetic field drives the permanent magnet 329 to perform a rotational movement, thereby realizing the rotational water pumping operation of the impeller 325 coaxially connected to the permanent magnet 329.

[0106] In some embodiments of the present application, the power supply can be selected as a power supply directly matching the alternating current required by the transmitting coil 326.

[0107] Alternatively, the power supply includes a first power conversion module and a second power conversion module. The first power conversion module is used to convert external commercial power into direct current; the second power conversion module receives the direct current output by the first power conversion module and converts it into the alternating current required by the transmitting coil 326.

[0108] That is, through the first power conversion module and the second power conversion module, the external commercial power is converted into the alternating current required by the transmitting coil 326, which is convenient for power taking and use. It can be connected to the power supply socket through the plug of the power cord 500.

[0109] The first power conversion module can be a rectifier to convert alternating current into direct current; the second power conversion module can be an inverter to convert direct current into alternating current.

[0110] In some embodiments of the present application, the refrigerator further includes a main control board box 400, which is arranged on the refrigerator body 100. A main control board is provided in the main control board box 400, and the first power conversion module and the second power conversion module are integrated on the main control board.

[0111] The main control board is an essential component of the refrigerator. The first power conversion module and the second power conversion module can be directly mounted on the main control board of the refrigerator itself, improving the integration level and eliminating the need to separately set relevant electrical components, which is beneficial to cost reduction.

[0112] Such as Figure 3 and Figure 4As shown, in some embodiments of the present application, the main control board box 400 is provided at the rear side near the top of the box body 100. The power cord 500 is led out from the back of the box body 100 and connected to a power supply socket through a plug. The main control board box 400 does not occupy the internal refrigeration space, which is beneficial to reducing the cost of the refrigerator.

[0113] In some embodiments of the present application, the water supply system 300 further includes a voltage stabilizing module 3210. The voltage stabilizing module 3210 is connected between the receiving coil 327 and the exciting coil 328, stabilizes and rectifies the alternating current generated by the receiving coil 327, and outputs the alternating current with a stable waveform to the exciting coil 328, so as to make the exciting coil 328 generate a stable alternating magnetic field, further making the impeller 325 rotate stably and the water supply amount stable.

[0114] The voltage stabilizing module 3210 is also provided in the sealing part 322 to isolate water.

[0115] Regarding the connection between the permanent magnet 329 and the impeller 325, as Figure 9 shown, the outer contour of the permanent magnet 329 is cylindrical, and it has a central through hole. The shaft 3211 of the impeller 325 is inserted into the central through hole of the permanent magnet 329 and is fixedly connected to the permanent magnet 329.

[0116] In some embodiments of the present application, as Figures 9 to 13 shown, a first installation cavity 3212 is formed on the housing 321. The water outlet 324 and the water inlet 323 communicate with the first installation cavity 3212. The permanent magnet 329 and the impeller 325 are provided in the first installation cavity 3212. The first installation cavity 3212 plays a certain protective role for the permanent magnet 329 and the impeller 325.

[0117] The impeller 325 is configured to be detachable. On the one hand, it can facilitate maintenance and repair. On the other hand, by replacing the impeller 325 with different radii, the water supply amount can be adjusted; the water supply amount can also be adjusted by changing the diameter of the water outlet 324.

[0118] The first installation cavity 3212 includes a cover body 3213 that is detachably provided. The water inlet 323 is provided on the cover body 3213, which further facilitates the maintenance and repair of the internal components of the first installation cavity 3212. As an implementation manner, the water inlet 323 can be provided at the central part of the cover body 3213.

[0119] The main body part of the first installation cavity 3212 can be an integral structure with the housing 321, or can be separately formed and connected to the outer wall of the housing 321 through fasteners. No specific limitation is made here.

[0120] The specific position of the water outlet 324 on the first installation cavity 3212 is not specifically limited either, as long as it is convenient to connect the water supply pipeline.

[0121] The cover body 3213 can be detachably arranged on the first installation cavity 3212 specifically by means of a snap 3214 structure or screw connection, etc.

[0122] As Figures 10 to 13 shown, the main body of the first installation cavity 3212 is annular, surrounded outside the impeller 325, and the cover body 3213 is correspondingly a circular cover body 3213. Two snaps 3214 are arranged on the outer peripheral wall thereof and are opposite to each other and have opposite extending directions. Two snaps are correspondingly arranged on the outer peripheral wall of the main body of the first installation cavity 3212. By rotating the cover body 3213 to engage or disengage the snaps 3214, the opening or locking of the cover body 3213 is realized.

[0123] In order to prevent impurities and foreign objects in the water in the water storage component 310 from entering the first installation cavity 3212, a filtering structure such as filter cotton can be arranged at the water inlet 323 on the cover body 3213 for filtering.

[0124] In some embodiments of the present application, as Figure 9 shown, the first installation cavity 3212 has a concave area 3215 recessed toward the side where the sealing part 322 is located, and the concave area 3215 extends toward the position where the excitation coil 328 is located.

[0125] The outer contour of the permanent magnet 329 is cylindrical, and the concave area 3215 is a cylindrical shape adapted to the permanent magnet 329. One end of it is closed and the other end is open. The permanent magnet 329 is rotatably inserted into the concave area 3215. The first axial end of the permanent magnet 329 faces the closed end of the concave area 3215, and the impeller 325 is located on the side where the second axial end of the permanent magnet 329 is located.

[0126] The concave area 3215 extends to the position where the excitation coil 328 is located, and the permanent magnet 329 is rotatably inserted into the concave area 3215, which can make the permanent magnet 329 as much as possible completely in the alternating magnetic field generated by the excitation coil 328, so that the permanent magnet 329 can perform stable mechanical rotation.

[0127] Taking Figure 9 the shown perspective as an example, the axis of the excitation coil 328 is vertical, the concave area 3215 extends to the upper area of the excitation coil 328, and the excitation coil 328 is shielded as much as possible from above, so that the permanent magnet 329 is as much as possible completely in the alternating magnetic field generated by the excitation coil 328.

[0128] In some embodiments of the present application, a wear-resistant part 3216 is arranged between the closed end of the concave area 3215 and the first axial end of the permanent magnet 329. The wear-resistant part 3216 can effectively reduce the wear of the corresponding housing 321 part of the concave area 3215 due to the rapid rotation of the permanent magnet 329, which is beneficial to extending the service life of the water supply system 300.

[0129] The wear-resistant component 3216 can be a POM pad, a PVC pad, a nylon pad, etc. Specifically, it can be fixedly arranged on the end face of the closed end of the concave area 3215 by means of gluing or interference fitting, and no specific limitation is made here.

[0130] In some embodiments of the present application, for the setting of the transmitting coil 326, it can be arranged on the outer wall of the bottom plate of the water storage component 310. Correspondingly, the receiving coil 327 is arranged on the inner wall of the bottom plate of the water storage component 310. On the basis of ensuring the separation of water and electricity, the transmitting coil 326 and the receiving coil 327 are made as close as possible to improve the wireless reception efficiency; the transmitting coil 326 can be configured to be an integral structure with the water storage component 310 or be detachably connected to the water storage component 310 according to design requirements.

[0131] Specifically, the transmitting coil 326 can be supported and fixed on the outer wall of the bottom plate of the water storage component 310 by a support plate 3217.

[0132] Since the water pumping assembly 320 needs to be immersed in the water of the water storage component 310 for a long time, the sealing performance requirement of the sealing part 322 is relatively high. Then in some embodiments of the present application, the sealing part 322 is formed by forming a second installation cavity 3218 on the housing 321 and filling the second installation cavity 3218 with an insulating sealing material. In this way, compared with the ordinary sealing structure of a sealing cavity plus a sealing strip, the sealing effect is more reliable.

[0133] In some embodiments of the present application, the insulating sealing material can be an epoxy resin filler, a polyurethane filler, an acrylic filler, etc., and no specific limitation is made here.

The water storage component 310 can be provided on the storage board in the refrigerating chamber.

[0139] The water pumping assembly 320 serves as the power assembly of the water supply system 300 and provides water pumping power. The water pumping assembly 320 includes a housing 321, a water supply pipe, a power source, a transmitting coil 326, a receiving coil 327, an electromagnetic generating device, and a magnetic rotating device.

[0141] One end of the water supply pipe is communicated with the water outlet 324, and the other end is communicated with the water using component.

[0142] The power source is provided outside the water storage component 310 to be separated from the water in the water storage component 310 and is convenient for external connection of electricity. The power source is used to output an alternating current to the transmitting coil 326.

[0143] The transmitting coil 326 is provided outside the water storage component 310 to be separated from the water in the water storage component 310 and is convenient for connecting the power source. The transmitting coil 326 is used to generate an alternating magnetic field.

[0144] The receiving coil 327 is provided in the sealing portion 322 to be separated from the water in the water storage component 310. The receiving coil 327 is placed corresponding to the transmitting coil 326, and the two can be arranged in parallel, and is used to generate an alternating current in the alternating magnetic field.

[0145] The electromagnetic generating device is provided in the sealing portion 322, and it generates an alternating magnetic field by using the alternating current generated by the receiving coil 327.
