In some embodiments, the coldair supply device 20 may further include a circulation fan, so that air in the storage compartment may be circulated through theevaporator 24 and the circulation fan. - The
refrigerator body 10 includes ahorizontal partition plate 11 disposed at a middle position of therefrigerator body 10 in a height direction. The height direction refers to the up-down direction inFIG. 1 , and thehorizontal partition plate 11 extends in a left-right direction inFIG. 1 . The substantial position of thehorizontal partition plate 11 is indicated by the dotted line box inFIG. 1 . The storage compartment is partitioned into anupper storage compartment 12 and alower storage compartment 13 by thehorizontal partition plate 11. In some embodiments, theupper storage compartment 12 is used as a freezing compartment for storing foods in a freezing mode, and thelower storage compartment 13 is used as a refrigerating compartment for storing foods in a refrigerating mode. - In addition, referring to
FIG. 1 , therefrigerator 1 may further include anice maker 1001, so that therefrigerator 1 has an ice making function, and ice cubes or ice water may be provided to the user by theice maker 1001. In some embodiments, theice maker 1001 is disposed in the freezing compartment, and in this case, the freezing compartment is the ice making compartment.FIG. 1 shows an example in which theice maker 1001 is disposed in the upper storage compartment 12 (i.e., the freezing compartment). Alternatively, an independent ice making compartment is defined by a heat insulating plate in the refrigerating compartment or the freezing compartment, and theice maker 1001 is disposed in the ice making compartment. - The
door body 30 is pivotally connected to therefrigerator body 10, so as to open or close the storage compartment by rotation. For example, thedoor body 30 is hinged to a front end of therefrigerator body 10. Fourdoor bodies 30 are shown inFIG. 1 . - Referring to
FIG. 3 , theice maker 1001 includes abase 100, a mold shell 400 (including ashell 200 and a mold body 300), and adriving mechanism 500. - As shown in
FIG. 3 , thebase 100 is configured to be connected to the ice making compartment. Thebase 100 includes a plurality of side plates. For example, the plurality of side plates include anupper side plate 101, aleft side plate 102, aright side plate 103, afront side plate 104, and a rear side plate. Theleft side plate 102 and theright side plate 103 face each other in the left-right direction, thefront side plate 104 and the rear side plate face each other in the front-rear direction, and theupper side plate 101 is located at the upper portion of theleft side plate 102, theright side plate 103, thefront side plate 104, and the rear side plate.

FIGS. 3 and 4 , themold shell 400 includes a firstsub-mold shell 401 and a secondsub-mold shell 402. The firstsub-mold shell 401 and the secondsub-mold shell 402 are switchable between a separated state and a closed state. In the closed state, the firstsub-mold shell 401 and the secondsub-mold shell 402 form a mold cavity, which is a cavity enclosed by the firstsub-mold shell 401 and the secondsub-mold shell 402. A shape of the mold cavity depends on shapes of inner contours of the firstsub-mold shell 401 and the secondsub-mold shell 402. The shape of the mold cavity is the shape of ice cubes. The shape of the mold cavity may be adaptively designed according to the needs of users. For example, the mold cavity may be designed into a spherical shape, a diamond-faced spherical shape, or a polyhedral shape. - In some embodiments, one of the first
sub-mold shell 401 and the secondsub-mold shell 402 is fixed, and the other of the firstsub-mold shell 401 and the secondsub-mold shell 402 is movable, such that the firstsub-mold shell 401 and the secondsub-mold shell 402 are switchable between the separated state and the closed state. In the separated state, the movable one of the firstsub-mold shell 401 and the secondsub-mold shell 402 moves away from the other one that is fixed; in the closed state, the movable one of the firstsub-mold shell 401 and the secondsub-mold shell 402 moves toward the other one that is fixed, until the two parts are closed. - For example, it may be that the first
sub-mold shell 401 is fixed, and the secondsub-mold shell 402 is movable relative to the firstsub-mold shell 401; it may also be that the secondsub-mold shell 402 is fixed, and the firstsub-mold shell 401 is movable relative to the secondsub-mold shell 402. In this case, theice maker 1001 is easy to control and has good reliability.FIGS. 3, 4, 8, and 9 show that the firstsub-mold shell 401 and the secondsub-mold shell 402 are in the dosed state, andFIGS. 5 and 10 show that the firstsub-mold shell 401 and the secondsub-mold shell 402 are in the separated state. - In some embodiments, it may also be that both the first
sub-mold shell 401 and the secondsub-mold shell 402 are movable. In this case, theice maker 1001 includes two push rods corresponding to the firstsub-mold shell 401 and the secondsub-mold shell 402, respectively. The two push rods are independent of each other, and there is no need to provide other structures such as connecting rods to demold ice. - The solution in which the
mold shell 400 includes more sub-mold shells is similar to the solution in which themold shell 400 includes the firstsub-mold shell 401 and the secondsub-mold shell 402 as described above, and details will not be repeated here. - For ease of description, some embodiments are mainly described by considering an example in which the second
sub-mold shell 402 is fixed, and the firstsub-mold shell 401 is movable relative to the secondsub-mold shell 402, however, this cannot be understood as a limitation of the present disclosure. - In some embodiments, as shown in
FIG. 3 , themold shell 400 includes ashell 200 and amold body 300. It will be noted that, theshell body 200 may also be referred to as a mold frame, and themold body 300 may also be referred to as a mold. Themold shell 400 includes the mold frame and the mold. - Referring to
FIGS. 3 and 6 , theshell 200 includes afirst shell portion 210 and asecond shell portion 220 disposed opposite each other. For example, thefirst shell portion 210 and thesecond shell portion 220 are disposed opposite each other in the MN direction shown inFIG. 6 . Thefirst shell portion 210 is located on the M side of thesecond shell portion 220, and thesecond shell portion 220 is located on the N side of thefirst shell portion 210; and the MN direction corresponds to the right-left direction of theshell 200. An inner wall of thefirst shell portion 210 is provided with a first inner cavity 212 (referring toFIG. 6 ), and an inner wall of thesecond shell portion 220 is provided with a second inner cavity, the second inner cavity is disposed opposite the firstinner cavity 212, and the second inner cavity may have a structure similar to that of the firstinner cavity 212. Thefirst shell portion 210 and thesecond shell portion 220 are switchable between a separated state and a dosed state. In the dosed state, thefirst shed portion 210 and thesecond shell portion 220 are dosed to form an inner cavity, and the inner cavity is defined jointly by the firstinner cavity 212 and the second inner cavity. - Referring to
FIGS. 3 and 6 , themold body 300 is disposed in the inner cavity, and themold body 300 includes afirst mold portion 310 and asecond mold portion 320. Thefirst mold portion 310 is connected to thefirst shell portion 210 so that thefirst mold portion 310 moves with thefirst shell portion 210. For example, afirst mold portion 310 is disposed in the firstinner cavity 212 of thefirst shell portion 210, and thefirst mold portion 310 includes a first concave cavity 311 (referring toFIG. 6 ) located on a side of thefirst mold portion 310 facing thesecond mold portion 320. Thesecond mold portion 320 is connected to thesecond shell portion 220 so that thesecond mold portion 320 is fixed relative to thesecond shell portion 220. For example, asecond mold portion 320 is disposed in the second inner cavity of thesecond shell portion 220, and thesecond mold portion 320 includes a second concave cavity 321 (referring toFIG. 13 ) located on a side of thesecond mold portion 320 facing thefirst mold portion 310. Thefirst mold portion 310 and thesecond mold portion 320 are switchable between a separated state and a closed state. In the closed state, thefirst mold portion 310 and thesecond mold portion 320 are closed to form a mold cavity, and the mold cavity is defined jointly by the firstconcave cavity 311 and the secondconcave cavity 321. - In some embodiments, referring to
FIGS. 6 and 13 , an edge of the firstconcave cavity 311 of thefirst mold portion 310 is provided with a first engaging portion 312 (referring toFIG. 6 ), an edge of the secondconcave cavity 321 of thesecond mold portion 320 is provided with a second engaging portion 322 (referring toFIG. 13 ), and the secondengaging portion 322 is configured to be matched with the first engagingportion 312. For example, one of the first engagingportion 312 and the secondengaging portion 322 is a convex rib, the other of the first engagingportion 312 and the secondengaging portion 322 includes a groove, and the groove is matched with the convex rib. In this way, by the cooperation of the first engagingportion 312 and the secondengaging portion 322, the fitting degree of thefirst mold portion 310 and thesecond mold portion 320 when they are closed may be improved, and the aesthetic degree of the appearance of the ice cubes may be improved. In this way, it may be possible to effectively prevent a protruding edge from appearing at a position where thefirst mold portion 310 and thesecond mold portion 320 are engaged and from affecting the appearance of the ice cubes. - In some embodiments, one of the first engaging portion and the second
engaging portion 322 may also be configured as a protruding portion or a raised portion, and another one of the first engaging portion and the secondengaging portion 322 may also be configured as a concave portion or a slot. As long as the first engaging portion and the secondengaging portion 322 are capable of matching together, the present disclosure is not limited thereto. - In some embodiments of the present disclosure, at least one of the
first mold portion 310 and thesecond mold portion 320 is configured to be deformable due to an external force. For example, both thefirst mold portion 310 and thesecond mold portion 320 are silica gel members. - Referring to
FIG. 6 , themold body 300 has awater inlet 301 in communication with the mold cavity, and thewater inlet 301 is an annular hole. Thebase 100 includes an opening 1011 (referring toFIG. 8 ) at a position of anupper side plate 101 corresponding to thewater inlet 301, and an external water pipe is connected with thewater inlet 301 through theopening 1011, so as to inject water into the mold cavity. For example, theopening 1011 is formed as a rectangular through hole that penetrates theupper side plate 101 in the thickness direction. - In some embodiments, the
mold body 300 includes a plurality of mold cavities,FIG. 12 shows an example in which themold body 300 includes three mold cavities, and each mold cavity includes onewater inlet 301. Awater tank 600 is provided above theshell 200, and thewater tank 600 includes awater distribution port 601 corresponding to eachwater inlet 301. Awater distribution pipe 602 communicated with thewater inlet 301 is provided at thewater distribution port 601. Referring toFIG. 4 , thewater tank 600 is fixed to thebase 100, and theopening 1011 is provided in theupper side plate 101 at a position corresponding to the water tank 600 (referring toFIG. 8 ). The provision of the plurality of mold cavities may increase the number of ice cubes theice maker 1001 can make at one time, and the provision of thewater tank 600 with thewater distribution port 601 may improve the water filling efficiency, thereby effectively improving the ice making efficiency. - In some embodiments, referring to
FIG. 13 , the plurality of mold cavities communicate with each other through water holes 302. For example, themold body 300 inFIG. 13 includes three mold cavities, and two adjacent mold cavities are communicated with each other through thewater hole 302. In this way, the water injected into the mold cavities may circulate in different mold cavities, thereby averaging the water amount in each mold cavity and reducing the weight difference between the ice cubes. - Since the amount of water injected each time is constant during ice making, if water leaks during water injection, the amount of water entering the mold cavities will decrease, and the weight of the produced ice cubes will be less than the preset weight, thereby resulting in decreased integrity of the ice cubes. In some embodiments, referring to
FIG. 13 , thewater inlet 301 is formed into a closed shape. For example, the structure defining thewater inlet 301 is an annular structure, and the inner side of the annular structure defines thewater inlet 301. An example in which thewater inlet 301 is funnel-shaped is shown inFIG. 13 . In this way, by forming thewater inlet 301 into a closed shape, water leakage may be avoided, and the integrity of the ice cubes may be well guaranteed. - In this way, when water is injected into the mold cavity through the
annular water inlet 301 during ice making, water will not leak from the gap where thewater inlet 301 is closed, thus preventing leaked water from forming ice outside the mold cavity and affecting the demolding process. In addition, it may also be possible to prevent the ice formed by leaked water from destroying the original shape of the ice cubes. Therefore, the shape of the ice cubes may be complete. - It can be understood that, if half of the
water inlet 301 is located in thefirst mold portion 310 and the other half of thewater inlet 301 is located in thesecond mold portion 320, when water leaks out of the mold cavity from the position where the two halves of thewater inlet 301 in thefirst mold portion 310 and thesecond mold portion 320 are engaged during water injection, the leaked water will freeze and cause the mold portions to be adhered together. Consequently, it will be difficult to separate thefirst mold portion 310 from thesecond mold portion 320 during subsequent demolding, thereby resulting in an unsmooth demolding process. - In some embodiments, the
water inlet 301 is formed on thefirst mold portion 310 or thesecond mold portion 320.FIG. 13 shows an example in which thewater inlet 301 is formed on thesecond mold portion 320, and thewater inlet 301 and thesecond mold portion 320 are a one-piece member. Of course, in some embodiments, thewater inlet 301 may be formed on thefirst mold portion 310, and thewater inlet 301 and thefirst mold portion 310 are a one-piece member. Thus, instead of forming thewater inlet 301 into two halves that can be closed, by forming thewater inlet 301 into a single piece on thefirst mold portion 310 or thesecond mold portion 320, the demolding difficulty may be reduced, and the demolding process may be made smooth. - Referring to
FIG. 6 , thefirst shell portion 210 includes afirst groove 211, and thefirst groove 211 is located on a side of thefirst shell portion 210 proximate to thesecond shell portion 220. Thesecond shell portion 220 includes asecond groove 221, and thesecond groove 221 is located on a side of thesecond shell portion 220 proximate to thefirst shell portion 210. In a case where thefirst shell portion 210 and thesecond shell portion 220 are in the closed state, thefirst groove 211 and thesecond groove 221 are closed jointly to define an avoidance opening surrounding an outer periphery of thewater inlet 301. Thewater inlet 301 is located in the avoidance opening. - The first
sub-mold shell 401 includes afirst shell portion 210 and afirst mold portion 310. Referring toFIGS. 3 to 6 , theice maker 1001 further includes apush rod 410. Thepush rod 410 is located on a side of thefirst shell portion 210 away from thesecond shell portion 220 and is positioned at a predetermined distance from the first shell portion 210 (referring to the distance L inFIG. 4 ). Thepush rod 410 is fixed to theright side plate 103. - It will be noted that, the first predetermined distance is a distance set according to the length of the
first push rod 410, the size of the internal space of theice maker 1001, and other factors. - The
first shell portion 210 includes a throughhole 212A located on a side of thefirst shell portion 210 away from the second shell portion 220 (referring toFIGS. 4 and 5 ). For example, inFIG. 4 , the throughhole 212A is provided on the M side of thefirst shell portion 210, thepush rod 410 matched with the throughhole 212A is provided at a predetermined distance L from thefirst shell portion 210 on the M side of thefirst shell portion 210, and thepush rod 410 passes through the throughhole 212A inFIG. 5 . Thepush rod 410 is provided on the inner side (e.g., the N side) of theright side plate 103 inFIG. 3 . - In some embodiments, referring to
FIGS. 3, 4, and 9 , an end face of a side of thepush rod 410 adjacent to thefirst mold portion 310 matches a contour surface of the firstconcave cavity 311 of thefirst mold portion 310. Thus, thepush rod 410 is conveniently pushed against thefirst mold portion 310, so that thefirst mold portion 310 is effectively deformed, and the ice cubes in thefirst mold portion 310 are demolded, thereby improving the demolding effect. - The second
sub-mold shell 402 includes asecond shell portion 220 and asecond mold portion 320. Thesecond shell portion 220 includes aheating mechanism 420, and theheating mechanism 420 is disposed on a side of thesecond shell portion 220 away from thefirst shell portion 210. In this way, the ice cubes are conveniently heated by theheating mechanism 420, which facilitates the demolding of the ice cubes from thesecond mold portion 320. For example, theheating mechanism 420 is disposed on the N side of thesecond shell portion 220 inFIG. 4 . In some embodiments, referring toFIG. 6 , theheating mechanism 420 includes a heating tube or a heating wire. Thedriving mechanism 500 is configured to drive the firstsub-mold shell 401 to move while the secondsub-mold shell 402 is fixed. For example, thedriving mechanism 500 is configured to drive thefirst shell portion 210 to move so that thefirst shell portion 210 is separated from or closed with the fixedsecond shell portion 220. Thefirst mold portion 310 moves with thefirst shell portion 210, and thesecond mold portion 320 is fixed relative to thesecond shell portion 220. - Upon demolding, the
heating mechanism 420 is first activated to melt the outer wall of the ice cubes, thereby demolding the ice cubes from thesecond mold portion 320. The ice cubes are then attached to thefirst mold portion 310. Then, when thefirst shell portion 210 is driven by thedriving mechanism 500 to move to a predetermined position, thepush rod 410 is pushed to thefirst mold portion 310 through the throughhole 212A, so that thefirst mold portion 310 is deformed by force, and the ice cubes located in thefirst mold portion 310 are ejected. Finally, the ice cubes are dropped into the ice storage box for the user to take. - The
refrigerator 1 provided in some embodiments of the present disclosure includes theice maker 1001. The ice tray of theice maker 1001 includes the firstsub-mold shell 401 and the secondsub-mold shell 402. One of the firstsub-mold shell 401 and the secondsub-mold shell 402 is fixed, and the other of the firstsub-mold shell 401 and the secondsub-mold shell 402 is movable, such that the firstsub-mold shell 401 and the secondsub-mold shell 402 are switchable between the separated state and the closed state. Theice maker 1001 is suitable for making ice cubes of special shapes, such as spherical ice cubes or polyhedral ice cubes, which can only be formed through the cooperation of the firstsub-mold shell 401 and the secondsub-mold shell 402. - In addition, by adopting a solution in which one of the first
sub-mold shell 401 and the secondsub-mold shell 402 is fixed and the other of the firstsub-mold shell 401 and the secondsub-mold shell 402 is movable, the driving components required are relatively simple and the overall space occupied by theice maker 1001 is small. - In some embodiments, the first
sub-mold shell 401 is movable, and thepush rod 410 is provided on the side of the firstsub-mold shell 401 away from the secondsub-mold shell 402. The secondsub-mold shell 402 is fixed and includes theheating mechanism 420. Upon demolding, theheating mechanism 420 is activated to cause the ice cubes to adhere to the firstsub-mold shell 401. When the firstsub-mold shell 401 moves to the predetermined position, thepush rod 410 is pushed against thefirst mold portion 310 through the throughhole 212A, so that thefirst mold portion 310 is deformed by force and ejects the ice cubes. This demolding structure is simple, and the demolding effect is reliable. - It will be noted that, demolding of the second
sub-mold shell 402 may adopt at least one of theheating mechanism 420 or deforming thesecond mold portion 320. - In some embodiments, the demolding of the second
sub-mold shell 402 is accomplished mainly by using theheating mechanism 420 to melt the outer walls of the ice cubes. In this case, the secondsub-mold shell 402 may not be provided with thesecond mold portion 320, as long as the secondsub-mold shell 402 may form a mold cavity with thefirst mold portion 310. Additionally or alternatively, the demolding of the secondsub-mold shell 402 is achieved by causing thesecond mold portion 320 to deform. It can be understood that the manner of causing thesecond mold portion 320 to deform, so as to achieve demolding of the secondsub-mold shell 402, is similar to the manner of causing thefirst mold portion 310 to deform, so as to achieve demolding of the firstsub-mold shell 401, and details will not be repeated here. - In some embodiments, the separating and closing movements of the
first shell portion 210 and thesecond shell portion 220 include at least a translational type of movement or a rotary type of movement, for which amatching driving mechanism 500 is provided respectively. - As shown in
FIG. 7 , in a case where thefirst shell portion 210 adopts a translational separating and closing movement, thedriving mechanism 500 includes a driving member (e.g., a motor 510), a driving shaft (e.g., a rotating shaft 520), agear set 530, arack 540, and a slidingrod 550. - Referring to
FIGS. 7 and 4 ,FIG. 4 is a structural diagram with the base 100 inFIG. 3 hidden. Thedriving mechanism 500 includes tworacks 540, and the tworacks 540 are disposed at both sides of the top of thefirst shell portion 210 in the moving direction, respectively (for example, the moving direction is the left-right direction, and the two racks are arranged in the front-rear direction). Thedriving mechanism 500 includes a plurality of slidingrods 550. For example, thedriving mechanism 500 includes two or four slidingrods 550. In a case where thedriving mechanism 500 includes two slidingrods 550, the two slidingrods 550 are connected to two corner positions of thefirst shell portion 210 and thesecond shell portion 220, respectively. In a case where thedriving mechanism 500 includes four slidingrods 550, the four slidingrods 550 are connected to four corner positions of thefirst shell portion 210 and thesecond shell portion 220, respectively. - The driving member is connected to the rotating shaft, so as to drive the rotating shaft to rotate. For example, the
motor 510 is connected to therotating shaft 520, and therack 540 is connected to therotating shaft 520 through the gear set 530 in a transmission manner. In this way, themotor 510 is capable of driving therotating shaft 520 to rotate, therotating shaft 520 drives theclear set 530 to rotate, and the gear set 530 drives therack 540 to move, thereby translating thefirst shell portion 210 along the slidingrod 550.FIG. 5 shows that thedriving mechanism 500 drives thefirst shed portion 210 to move to the separated state, andFIGS. 3 and 4 show that thedriving mechanism 500 drives thefirst shell portion 210 to move to the closed state. It will be noted that, in some embodiments of the present disclosure, that the shell portion adopts a translational opening-closing movement means that thefirst shell portion 210 or thesecond shell portion 220 drives any one of shell portions or any one of mold portions to move in a translational opening-closing manner through a translational driving system (i.e., a translational rack and a slide rod). The function of the translational opening-closing movement is to ensure that the position of the shell portion and the mold portion before and after the opening-closing movement is fixed, so that there is no positional deviation due to the movement, which makes the translational opening-closing movement more reliable. As a result, it may be possible to avoid a situation that two mold portions are not sealed tightly and form gaps, thus water may leak out of the mold cavity from a mold-closing line of the water injecting hole during water injecting, and the regularity and appearance of the ice cube may be affected due to the difficulty of demolding when the ice making process is completed. - Referring to
FIGS. 8 to 11 , in a case where thefirst shell portion 210 adopts a rotary separating and closing movement, thedriving mechanism 500 includes a driving member and a driving shaft. In some embodiments, the driving member includes amotor 510, and the driving shaft includes arotating shaft 520. Themotor 510 is connected to therotating shaft 520, so as to drive therotating shaft 520 to rotate, and thefirst shell portion 210 is connected to therotating shaft 520. In this way, thefirst shell portion 210 may be rotated in a predetermined direction through the rotation of therotating shaft 520.FIG. 10 shows that thedriving mechanism 500 drives thefirst shell portion 210 to move to the separated state, andFIGS. 8 and 9 show that thedriving mechanism 500 drives thefirst shell portion 210 to move to the closed state. - Referring to
FIG. 11 , theice maker 1001 further includes a fixingshaft 503, and in this way, the connection of thesecond shell portion 220 to thebase 100 is facilitated by the fixingshaft 503. In some embodiments, thesecond shell portion 220 is connected to the fixingshaft 503. Alternatively, thesecond shell portion 220 is fixedly connected to thebase 100. - The foregoing descriptions are merely specific implementations of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions conceived by those skilled in the art within the technical scope disclosed in the present disclosure shall fall within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
