Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.

It will be appreciated that terms such as "upper," "lower," "outer," "inner," and the like, as used herein, refer to spatially relative positions and are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The term spatially relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

The device may be otherwise oriented (rotated 90 degrees or other orientations) and the spatially relative descriptors used herein interpreted accordingly. As in the present invention, for convenience of description, when the refrigerator is normally used, the direction toward the ground is downward, and the direction away from the ground is upward; the direction parallel to the ground is the horizontal direction, and the direction perpendicular to the ground is the vertical direction; the side close to the user is the front side, and the side far away from the user is the rear side.

The preferred embodiment of the invention provides a refrigerator which comprises an ice maker and an ice discharging device, wherein the ice discharging device is used for outputting ice cubes made by the ice maker to the outside of the refrigerator for a user to use.

Specifically, referring to fig. 1, a preferred embodiment of the present invention provides an ice discharging device including an ice bank 10 and an ice discharging assembly 20 connected to the ice bank 10. In this embodiment, the ice storage case 10 is disposed below an ice maker, the ice maker has an ice tray for forming ice cubes, and the ice tray pours the ice cubes into the ice storage case 10 for storage by an ice turning mechanism for a user to take. The ice discharging device utilizes the ice discharging assembly 20 to output ice cubes in the ice storage box 10 to the outside of the ice storage box 10 for a user to take.

Specifically, the refrigerator further includes an ice storage compartment accommodating the ice bank 10, the ice storage compartment being cooled by a refrigerating system including a compressor, a condenser, a capillary tube, an evaporator, and the like. The ice storage compartment can be arranged in the refrigerator body or in the door body of the refrigerator.

As shown in fig. 2, in detail, the ice bank 10 includes an ice storage chamber 11 and an ice guiding opening 13 communicating with the ice storage chamber 11. In this embodiment, ice cubes are stored in the ice storage chamber 11, and the ice cubes in the ice storage chamber 11 are output to the outside of the ice storage chamber 11 through the ice guiding opening 13.

Further, the ice discharging assembly 20 includes a rotation shaft 21 connected to the ice bank 10 and an ice guiding structure 23 connected to the rotation shaft 21 and matched with the ice guiding opening 13. In this embodiment, the refrigerator further includes a motor connected to the rotating shaft 21 in a transmission manner, and the rotating shaft 21 is driven by the motor to rotate. The ice guide structure 23 is fixedly connected with the rotating shaft 21, and the rotating shaft 21 drives the ice guide structure 23 to rotate after rotating. The ice guiding structure 23 is at least partially rotatable within the ice guiding opening 13 so as to continuously output ice cubes of the ice guiding opening 13 out of the ice storage cavity 11.

Further, the refrigerator further comprises a magnetic part 30 connected with the ice guiding structure 23, and a Hall sensing part fixed in the ice storage compartment and matched with the magnetic part 30. In this embodiment, the magnetic member 30 is rotated along with the ice guiding structure 23 by a certain angle and then abuts against the hall sensing member, and senses with the hall sensing member, so that the angle through which the ice guiding structure 23 rotates is determined by the sensing times of the hall sensing member.

As shown in fig. 3, in detail, the ice guiding structure 23 has a plurality of ice guiding grooves 23a recessed toward the rotation shaft 21 and extending along the axis of the rotation shaft 21. In this embodiment, since the ice guiding groove 23a is recessed at the outer edge of the ice guiding structure 23, when the ice guiding structure 23 rotates in the ice guiding opening 13, the ice cubes fall into the ice guiding groove 23a by gravity, so as to be output out of the ice storage cavity 11 along with the rotation of the ice guiding structure 23. As can be seen from fig. 1, the axis of the rotary shaft 21 is parallel to the front-rear direction, i.e., the ice guiding groove 23a extends in the front-rear direction. As shown in fig. 3, the plurality of ice guiding grooves 23a are each provided in a long-strip-shaped groove structure extending along the axis of the rotating shaft 21, the number of ice cubes received in each ice guiding groove 23a is equal, and the rotation axis of the ice guiding structure 23 is collinear with the axis of the rotating shaft 21, so that when the ice guiding structure 23 rotates with the rotating shaft 21 in the ice guiding opening 13, the ice cubes flowing into the ice storage cavity 11 at the ice guiding opening 13 easily enter the ice guiding grooves 23a, and thus rotate outside the ice storage cavity 11 with the ice guiding structure 23.

Of course, in some embodiments, the extending direction of the ice guiding groove 23a may be disposed at an angle to the axis of the rotating shaft 21.

Further, when the ice guiding structure 23 rotates along with the rotating shaft 21, the plurality of ice guiding grooves 23a sequentially and completely penetrate the ice guiding opening 13 and are exposed in the ice storage cavity 11. In this embodiment, all the ice guiding grooves 23a can completely penetrate the ice guiding opening 13 during the rotation of the plurality of ice guiding grooves 23a along with the ice guiding structure 23, however, at most only one ice guiding groove 23a can completely penetrate the ice guiding opening 13 at any time, that is, the plurality of ice guiding grooves 23a sequentially penetrate the ice guiding opening 13 one by one according to the rotation sequence. In this way, it is ensured that each ice guiding groove 23a is filled with ice cubes and then rotates along with the ice guiding structure 23 to the outside of the ice storage cavity 11.

When the ice guiding structure 23 rotates along with the rotating shaft 21, at most one ice guiding groove 23a completely penetrates through the ice guiding opening 13 and is exposed into the ice storage cavity 11 at the same time, so that ice cubes in the ice storage box 10 fill the plurality of ice guiding grooves 23a in sequence, and the quantity of the ice cubes in each ice guiding groove 23a is the same, and the quantity of the ice cubes output by the ice outputting device is stable.

Specifically, the plurality of ice guiding grooves 23a are uniformly arranged circumferentially around the axis of the rotating shaft 21, the length of each ice guiding groove 23a along the axis direction of the rotating shaft 21 is equal to the length of the ice guiding opening 13 along the axis direction of the rotating shaft 21, and the maximum groove width of each ice guiding groove 23a along the axis direction perpendicular to the rotating shaft 21 is not greater than the width of the ice guiding opening 13 along the axis direction perpendicular to the rotating shaft 21.

In this embodiment, the length of the ice guiding groove 23a along the front-rear direction is equal to the length of the ice guiding opening 13 along the front-rear direction, that is, the groove length of the ice guiding groove 23a, the ice guiding groove 23a completely penetrates the ice guiding structure 23 along the axial direction of the rotating shaft 21 to extend to form a long strip-shaped through groove structure, so that ice cubes can enter the ice guiding groove 23a conveniently. The plurality of ice guide grooves 23a are uniformly disposed circumferentially along the rotation axis of the ice guide structure 23 such that the time required for each ice guide groove 23a to output ice cubes is the same, thereby enabling the ice-making assembly 20 to continuously and uniformly output ice cubes.

Further, the maximum groove width of the ice guiding groove 23a in the left-right direction means a dimension of the ice guiding groove 23a in the left-right direction directing an opening of one end of the ice guiding groove 23a away from the rotation shaft 21, that is, a groove width dimension of the ice guiding groove 23a, and a dimension of the ice guiding groove 23a in the radial direction of the rotation shaft 21 is a groove depth dimension of the ice guiding groove 23a. The reason why the groove width dimension of the ice guiding groove 23a is smaller than or equal to the dimension of the ice guiding opening 13 in the left-right direction is that, in the specific arrangement, the ice guiding can not be performed when the ice guiding opening 13 is arranged too small after the groove width dimension and the groove depth dimension of the ice guiding groove 23a are set to be matched with the ice cubes, namely, the two dimensions are both larger than 2-3mm of the maximum dimension of the ice cubes.

Of course, in some embodiments, the groove width dimension and the groove depth dimension of the ice guiding groove 23a may be set to be larger than the dimension of the ice cubes, and the dimension of the ice guiding opening 13 may be also larger than the dimension of the ice cubes, and in this case, the groove width dimension of the ice guiding groove 23a may be set to be larger than the dimension of the ice guiding opening 13 in the left-right direction.

Further, the maximum groove width of the ice guiding groove 23a along the direction perpendicular to the axis of the rotating shaft 21 is smaller than the width of the ice guiding opening 13 along the direction perpendicular to the axis of the rotating shaft 21, so that the ice guiding structure 23 is at least partially exposed in the ice storage cavity 11.

In this embodiment, the width of the ice guiding groove 23a is smaller than the size of the ice guiding opening 13 in the left-right direction, the size of the ice guiding groove 23a is adapted to the size of the ice cubes and is four, so that the amount of the ice cubes passing through the ice guiding opening 13 is larger than the amount of the ice accommodated in the ice guiding groove 23a, and the ice cubes enter the ice guiding groove 23a through the rotation of the ice guiding structure 13 exposed in the ice storage cavity 11, and the amount of the ice cubes entering the four ice guiding grooves 23a is the same.

Of course, in some embodiments, the groove width dimension of the ice guiding groove 23a may also be set to be equal to the dimension of the ice guiding opening 13 in the left-right direction.

Further, the ice bank 10 includes a first case 15 forming the ice storage cavity 11, at least one partition 17 connected to the first case 15 and located in the ice storage cavity 11, the partition 17 extending along a plane perpendicular to an axis of the rotation shaft 21 and being connected to a side edge of the ice guiding opening 13.

In this embodiment, referring to fig. 2 and 3, the partition 17 equally separates a part of the space of the ice storage cavity 11 along the front-rear direction, so that the ice cubes flowing from the ice storage cavity 11 to the ice guiding opening 13 can be separated, the effect of diversion is achieved, and the ice cubes cannot enter the ice guiding groove 23a due to extrusion between the ice cubes, so that the ice cubes can enter the ice guiding groove 23a more smoothly.

Further, the ice bank 10 further includes a second case 19 connected to the first case 15 and matched with the ice guiding structure 23, an ice inlet 15a formed on the first case 15, and an ice outlet 19a formed on the second case 19, wherein the ice inlet 15a, the ice guiding opening 13, and the ice outlet 19a are arranged in a vertical direction.

In this embodiment, the direction of movement during the entry and exit of ice cubes from the ice bank 10 is perpendicular to the axis of the rotary shaft 21. As shown in fig. 2, ice cubes enter the ice storage cavity 11 from top to bottom by self gravity, sequentially pass through the ice inlet 15a, enter the ice guide groove 23a through the ice guide opening 13, and finally are discharged out of the ice storage box 10 through the ice outlet 19a, so that the ice cubes can be conveyed from the ice inlet 15a to the ice guide opening 13 without any auxiliary device, and the manufacturing cost and energy consumption of the refrigerator are saved.

Specifically, the first shell 15 includes a storage portion 15b forming an ice inlet 15a, and an ice guiding portion 15c connected to the storage portion 15b and forming an ice guiding opening 13, the ice guiding opening 13 is disposed at the lowest point of the ice guiding portion 15c, and the partition 17 is connected to the inside of the ice guiding portion 15 c. In this embodiment, as shown in fig. 2 and 3, the ice guiding portion 15c has an inverted cone structure, so that ice cubes can be gathered at the ice guiding opening 13 from the ice storage cavity 11. The partition 17 is connected to the upper side of the ice guiding opening 13 and to the left and right side edges of the ice guiding opening 13.

As shown in fig. 4, the ice guiding structure 23 further includes a plurality of ice guiding members 23b connected to the rotating shaft 21 and disposed at intervals along the axial direction of the rotating shaft 21, and the ice discharging assembly 20 further includes ice crushing members 25 disposed between adjacent ice guiding members 23b, wherein at least a portion of the ice crushing members 25 is exposed in the ice guiding grooves 23a when the ice guiding structure 23 rotates.

In this embodiment, when the ice guiding groove 23a drives the ice cubes to contact with the ice crushing portion 25, the ice cubes can be crushed to form crushed ice, and the crushed ice continues to rotate along with the ice guiding groove 23a, so that the ice storage box 10 is discharged, and the requirement of users for ice cubes with different sizes is met. As shown in fig. 5, when the ice guide groove 23a rotates clockwise, the ice cubes are not contacted with the ice crushing member 25 from the entrance of the ice guide groove 23a to the discharge of the ice guide groove 23a, and the discharged ice cubes are whole ice; when the ice guide groove 23a rotates counterclockwise, ice cubes enter the ice guide groove 23a and are contacted with the ice crushing member 25 and pressed after rotating along with the ice guide groove 23a, and the crushed ice is generated to continue to be discharged out of the ice bank 10 along with the ice guide groove 23a.

Specifically, the second shell 19 includes two mounting walls 19b connected to the rotating shaft 21, two side walls 19c connected to the two mounting walls 19b and matched with the ice guiding piece 23b, the central axis of the ice guiding piece 23b is collinear with the central axis of the two side walls 19c, the two mounting walls 19b and the two side walls 19c are connected to the side edges of the ice guiding opening 13, and the ice outlet 19a is formed on the side edges of the two mounting walls 19b and the two side walls 19c facing away from one end of the ice guiding opening 13.

In this embodiment, the ice guiding member 23b is of a central symmetrical structure, the two side walls 19c are of a circular arc structure matched with the ice guiding member 23b, and the two side walls 19c are oppositely arranged at the left and right sides of the ice guiding structure 23, so that the resistance applied when the ice cubes contact with the inner wall of the second shell 19 is reduced, and the whole ice and crushed ice can be conveniently discharged out of the second shell 19. The side edges of the ice guiding opening 13 are directly connected with the two mounting walls 19b and the two side walls 19c, so that the formation of accumulation of ice residues generated during ice crushing in the second shell 19 below the side edges of the ice guiding opening 13 is avoided.

Further, the refrigerator includes four magnetic members 30 disposed on the ice guide 23b, and the four magnetic members 30 are uniformly disposed along the central axis of the ice guide 23b in the circumferential direction. In this embodiment, as shown in fig. 2, four magnetic members 30 are disposed on the peripheral edge of the ice guiding member 23b, so that the hall sensing member can sense with the four magnetic members 30.

Specifically, the ice guiding member 23b includes an ice guiding member main body 23b1 and a plurality of ice guiding notches 23b2 disposed on the ice guiding member main body 23b1, the ice guiding notches 23b2 of adjacent ice guiding members 23b are arranged along the axis of the rotating shaft 21 to form an ice guiding groove 23a, the ice guiding notches 23b2 have an ice guiding cavity 23b21 near one side of the central axis of the ice guiding member 23b and an ice guiding channel 23b22 communicating with the ice guiding cavity 23b21, and the symmetry axis of the ice guiding cavity 23b21 and the symmetry axis of the ice guiding channel 23b22 are collinear with each other.

In this embodiment, the entire ice guiding notch 23b2 has a symmetrical structure. The ice guide chamber 23b21 is preferably provided in a circular arc shape so as to be suitable for ice cubes of various shapes, particularly for spherical ice. The ice guide channels 23b22 are of symmetrical plane structures, so that ice cubes can enter the ice guide cavity 23b21 smoothly.

Further, the ice crushing member 25 has an ice crushing portion 25a connected to the rotation shaft 21 and located in the second case 19, and a connecting portion 25b connecting the ice crushing portion 25a with the first case 15, the ice crushing portion 25a has a serration section 25a1 located at the top, and the vertical height of the ice crushing portion 25a increases gradually from the rotation shaft 21 toward the connecting portion 25 b.

In this embodiment, as shown in fig. 2, when the ice guiding groove 23a rotates counterclockwise, ice cubes enter the ice guiding groove 23a and contact and squeeze the ice crushing member 25 as the ice guiding groove 23a rotates, and the ice cubes are parallel to each other in a direction of being reacted by the ice crushing member 25 by a squeezing force applied from the ice guiding groove 23a in the circumferential direction, thereby making the ice crushing effect better.

The specific embodiment of the invention also relates to a control method of the refrigerator, and the structure and the function of the refrigerator are as described above and are not repeated here.

As shown in fig. 5, the refrigerator provided in the above embodiment further relates to a control method for a refrigerator, the control method comprising the steps of:

s1, acquiring an ice outlet instruction;

s2, controlling the ice guide structure 23 to rotate at a preset rotating speed;

and S3, after the rotation angle a2 of the ice guide structure 23 reaches the set angle a1, controlling the motor to stop rotating.

In this embodiment, the motor is utilized to drive the ice guiding structure 23 to rotate, so that ice cubes are uniformly and stably output to the outside of the ice storage box 10, and the amount of the output ice cubes is controlled by controlling the rotation angle of the ice guiding structure 23, so that the ice output of the ice storage box 10 is accurately controlled, and the use experience of a user is improved.

Specifically, in the step S3, the number of times of matching between the hall sensing element and the magnetic element 30 is obtained to calculate the rotation angle a2 of the ice guiding structure.

In this embodiment, the magnetic member 30 is rotated along with the ice guiding structure 23 by a certain angle and then abuts against the hall sensing member, and senses with the hall sensing member, so that the rotated angle of the ice guiding structure 23 is determined by obtaining the sensing times of the hall sensing member.

Of course, in some embodiments, when the motor is directly connected to the ice guiding structure 23, the rotated angle of the ice guiding structure 23 may also be determined by acquiring the rotation angle of the motor. At this time, the magnetic member 30 may be disposed on the output shaft of the motor so as to be engaged with the hall sensing member.

Further, in the step S3, after the ice guiding groove 23a rotates by the angle a1 along with the ice guiding structure 23, the number of ice cubes outputted from the ice guiding structure 23 to the outside of the ice bank 10 is calculated as N1 according to the angle of rotation of the ice guiding groove 23a.

In this embodiment, the number of ice cubes outputted from each ice guiding groove 23a to the outside of the ice bank 10 is constant, and the outputted ice cube number N1 can be obtained by obtaining the rotated angle of the ice guiding groove 23a and multiplying the number of ice cubes outputted from each ice guiding groove 23a.

Further, in the step S1, a start signal of the ice maker is obtained, and the number N2 of ice cubes falling into the ice bank 10 is calculated according to the number of times of turning ice of the ice tray. In this embodiment, the number of ice cubes produced by the ice maker is constant each time the ice tray is made, and the number of times of turning ice of the ice tray is multiplied, so that the number of ice cubes N2 produced by the ice maker can be obtained.

Further, in the step S3, after the motor stops rotating, the value of N2-N1 is calculated to obtain the ice storage amount N3 in the ice bank 10.

In this embodiment, since the ice storage box 10 can accurately obtain the value of the ice quantity N1 output by the ice outlet assembly 20, the ice quantity N3 remaining in the ice storage box 10, that is, the real-time ice storage quantity N3 of the ice storage box 10 can be obtained by subtracting the ice quantity N1 output by the ice outlet assembly 20 from the ice quantity N2 produced by the ice maker, and the ice storage quantity N3 can be displayed on the panel of the refrigerator through the display device, so that the user can conveniently check. And, the ice storage amount N3 of the ice bank 10 cannot be less than zero, and if the calculated value of N2-N1 is less than zero, it is calculated as zero, for example, when the refrigerator is first used, the ice maker does not make ice, and the user activates the ice taking function.

In this way, the ice bank 10 does not need to use an ice lever or other ice amount detecting means to obtain the ice cubes N3 in the ice bank 10, thereby saving manufacturing costs.

Further, in the step S1, after the ice instruction is obtained, when the ice amount N4 is less than or equal to the ice storage amount N3, the ice maker is turned off, and the motor is started.

In this embodiment, the refrigerator has a storage function, and records and stores the remaining ice storage amount N3 in the ice bank 10 after the previous ice-discharging operation, and the user makes a call when taking ice again, thus reciprocating. Also, the user may want to turn off the ice maker by setting N4 to 0.

Further, in the step S1, after the ice instruction is obtained, when the ice amount N4 is greater than Chu Bingliang N3, the ice maker is started, and the motor is started. In this embodiment, the motor can drive the ice guiding structure 23 to rotate after being started, so as to realize ice discharging of the ice assembly 20.

Further, in the step S3, after the motor stops rotating, a value of N2-n1+n3 is calculated to obtain the ice storage amount N3' in the ice bank. In this embodiment, the value of N3 is the amount of ice stored in the ice bank 10 in the previous ice-out cycle, and is directly called in the current ice-out cycle. Of course, the value of the ice storage amount N3 in the ice bank 10 may be manually changed, thereby preventing the refrigerator from being powered off or the user from taking ice through the ice outlet 19a, and the like, and correcting the ice storage amount N3 to ensure the accuracy of the ice storage amount N3.

Specifically, in the step S3, the value of N1 is equal to the ratio of the angle a1 to 45 ° multiplied by the number of ice cubes in the single ice guiding groove 23a. In this embodiment, the angle a1 is calculated by the sensing number of the hall sensing element.

Specifically, in step S1, the obtaining the ice-making instruction includes obtaining an ice-making instruction and obtaining an ice-crushing instruction, where a rotation direction of the motor when the ice-making instruction is obtained is opposite to a rotation direction of the motor when the ice-crushing instruction is obtained. In this embodiment, the rotation direction of the motor is changed to select whether the ice discharging assembly 20 outputs whole ice or crushed ice, so as to meet different needs of users.

Specifically, in the step S3, the value of N1 is equal to the number of times that the hall sensing element is turned on with the magnetic element 30 multiplied by the number of ice cubes in the single ice guiding slot 23a. In this embodiment, when the hall sensing element is electrically connected to any one of the four magnetic elements 30, this means that the ice guiding mechanism 23 outputs the number of ice cubes carried by one ice guiding slot 23a, so that the number N1 of ice cubes output by the whole ice guiding mechanism 23 is more easily obtained. Moreover, since the ice guiding mechanism 23 has four ice guiding grooves 23a, the number of the magnetic pieces 30 corresponds to the four ice guiding grooves 23a, so that the ice guiding mechanism 23 is rotated by 45 degrees as a unit ice outlet angle, and then the lowest lower limit value of the ice taking amount of a user is reduced, so that the adjustment range of the ice outlet amount of the user is larger.

Specifically, in the step S2, the rotational angular speed of the ice guiding structure 23 is set to 0.5-0.8 rad/S. In this embodiment, the angular speed at which the ice guiding structure 23 rotates can be set according to the volume and the number of ice cubes.
