Detailed Description

In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships that, without particular explanation, are based on the orientations or positional relationships shown in the drawings only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

According to the present invention, an ice bank is provided, comprising an ice bank body 2 and an inlet on the ice bank body 2, the inlet being configured as an ice inlet. Further, the ice bank further includes a door mechanism 7 configured to open and close an ice inlet. The door mechanism 7 includes a plurality of door leaves, and the door mechanism 7 is configured to: when the door mechanism 7 is opened, the plurality of door leaves form a guide passage configured to guide the ice cubes to fall.

The door mechanism 7 includes an open state and a closed state. When the door mechanism 7 is opened, ice cubes can enter the ice storage box through the inlet. When the door mechanism 7 is closed, ice cubes cannot enter the ice bank through the inlet.

This kind of ice storage box through closing door body mechanism 7, can reduce or even eliminate the influence of ice making district to the inside temperature of ice storage box completely, and then guarantee the storage of ice-cube. In addition, when the door mechanism 7 is opened, the inlet is opened relative to the ice making area, so that the prepared ice blocks fall off and then enter the ice storage box through the inlet. And because a guide channel is formed among the plurality of ice blocks, the ice blocks can be guided, so that the ice blocks are prevented from scattering everywhere, and all the ice blocks are ensured to enter the ice storage box through the ice making area.

In one embodiment, when door mechanism 7 comprises a double door, the double door comprises a first door leaf and a second door leaf. When the door body mechanism 7 is closed, the first surfaces of the first door leaf and the second door leaf are positioned at the inner side of the ice storage box; when the door body mechanism 7 is opened, a guide channel is formed between the first door leaf and the second door leaf, and the first surface is located on the outer side of the guide channel. In this case, ice cubes or water droplets can be prevented from contacting the first surface of the door mechanism 7. Furthermore, when the door mechanism 7 is closed, the first surface located inside the ice bank does not affect the temperature of the inner cavity of the ice bank, so that the temperature of the inner cavity of the ice bank is maintained at a state lower than the temperature of the ice making area.

It should be noted that the embodiment describes the door mechanism of the present invention by taking a double door as an example. But the door body mechanism can also be selected into a three-door structure, a four-door structure or even any structure with multiple doors. Further, the number of door leaves of the door body mechanism is not limited.

In one embodiment, the door mechanism 7 is disposed at the inlet, and when the door mechanism 7 is closed, the door mechanism 7 can completely block the inlet, so that the inner cavity of the ice storage box is completely isolated from the external environment.

Of course, the door mechanism 7 may be disposed outside the inlet, i.e., on a side away from the ice bank with respect to the inlet, and a certain distance is reserved between the door mechanism 7 and the inlet. In this case, the door mechanism 7 can prevent a direct heat exchange between the ice bank cavity and the ice making region, but cannot completely seal the ice bank cavity.

The ice bank of the present invention will be further described with reference to the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the ice bank includes a first rail assembly fixed with respect to the ice bank body 2, but the first rail assembly may also be directly formed on the ice bank. Wherein the first rail assembly includes a first rail 20 and a second rail 24 disposed on both sides of the entrance. The double door type door body mechanism includes a first door leaf and a second door leaf, which are disposed between the first guide rail 20 and the second guide rail 24. Wherein, the first side of the first door leaf and the second door leaf close to each other is connected with the first guide rail 20 and the second guide rail 24 through a sliding part, and the second side of the first door leaf and the second door leaf far away from each other is connected with the rotary driving mechanism 3.

It should be noted that "first side" and "second side" are merely relative concepts. Taking the first door leaf as an example, any area closer to the second door leaf than to the "first side" falls within the range covered by the "second side"; any area further away from the first door leaf with respect to the "second side" falls within the scope covered by the "first side".

Wherein the first rail 20 of the first rail assembly is visible in fig. 5 and the second rail 24 of the first rail assembly is visible in fig. 6.

It should be noted that in some cases, the first door leaf and the second door leaf may share the same first track assembly. Of course, the first rail assemblies of the first door leaf and the second door leaf may be independent of each other.

The first track 20 and the second track 24 may be arranged in a parallel configuration to facilitate engagement with a correspondingly configured door.

Wherein the specific extending direction of the first rail 20 and the second rail 24 is not limited. For example, the first rail 20 and the second rail 24 may be made to extend in a straight direction, and as shown in fig. 5 and 6, the first rail 20 and the second rail 24 may each include a straight rail section and a curved rail section.

In one embodiment, the specific structural form of the slider and the first rail assembly is not limited as long as the slider can slide relative to the first rail assembly. For example, in fig. 5 and 6, the first guide rail 20 and the second guide rail 24 are formed with sliding grooves, and the sliding member may be in the form of a sliding shaft, so that the sliding shaft is installed in the sliding grooves and can move along the sliding grooves under the action of external force.

In fig. 1 and 2, the door mechanism 7 is in a closed state, and the inner cavity of the ice bank is sealed by the door mechanism 7, so that the temperature inside the ice bank can be better maintained in a lower state.

In fig. 3 and 4, the door mechanism 7 is in an open state. As can be seen from fig. 3 and 4, a guide channel may be formed between the first door leaf and the second door leaf. As can also be seen from fig. 3 and 4, it is obvious that it is not possible to use a side-hung door to open or close the entrance in order to form a guide channel between the first door leaf and the second door leaf.

It is worth mentioning that the purpose of controlling the change trend of the cross section of the guide channel can be achieved by controlling the inclination angles of the first door leaf and the second door leaf. In fig. 3 and 4, the door leaves (including the first door leaf and the second door leaf) of the door body mechanism 7 are different in opening degree, and further, the trend of the change of the cross section of the guide channel is also different.

In one embodiment, the guide channel converges in a direction near the inlet to effect guidance of the ice pieces. Wherein the guide channel may gradually close in a direction near the inlet to prevent the ice cubes from splashing due to abrupt change of the guide channel structure.

In one embodiment, the rotary drive mechanism comprises a power unit, a transmission gear, and a drive rod 6 connected in series. Of course, the structural form of the rotation driving mechanism is not limited by the examples, as long as the door leaves (the door leaves in the present invention refer to a plurality of door leaves of the door body mechanism, and when the door body mechanism includes a double door, the door leaves refer to the first door leaf and the second door leaf) can be driven to rotate. For example, the transmission gear can also be replaced by a transmission belt or a transmission chain.

As can be seen from fig. 2, the rotation drive mechanism is provided at one end of the first door and the second door close to the first rail 20. Further, on the second side of the first door and the second door, a follower lever 21 is provided at one end of the first door and the second door close to the second rail 24. Furthermore, when the rotation driving mechanism drives the second sides of the first door leaf and the second door leaf to rotate, the driven rod 21 rotates along with the first door leaf and the second door leaf, and the stability of the first door leaf and the second door leaf is ensured.

Referring to fig. 7, the rotary drive mechanism 3 includes a front housing 16 and a rear housing 22. A transmission gear is provided between the front housing 16 and the rear housing 22. Wherein the transmission gear comprises a driving gear 18, a first driven gear 17 and a second driven gear 19. In addition, a power unit is disposed outside the front housing 16 and the rear housing 22, and the power unit passes through the rear housing 22 to rotate the driving gear 18. The power unit of fig. 7 is selected from one of a plurality of power unit forms, such as an electric motor 23.

Of course, the specific structure of the rotary drive mechanism 3 is not limited to fig. 7.

Here, a stopper may be provided on the front case or the rear case to ensure that the first driven gear 17 and the second driven gear 19 rotate within a design range. And, the first driven gear 17 and the second driven gear 19 can adopt a non-full-tooth design, thereby reducing the preparation cost of the ice bank while simplifying the processing technology.

Referring to fig. 8, the first door leaf and the second door leaf include a sealing layer, an insulating layer 14, and a covering layer, and the sealing layer, the insulating layer, and the covering layer are configured to be sequentially disposed. Wherein the first surface is formed on the sealing layer. Under this kind of condition, first door leaf and second door leaf have better sealed, the heat preservation effect.

The sealing layer may be in the form of a sealing frame 15, and the cover layer may be in the form of a cover plate 13. At this time, the sealing frame 15 and the covering plate 13 can be connected by clamping, and the insulating layer 14 is clamped between the sealing frame 15 and the covering plate 13. In addition, the sealing frame 15 can be a flexible body, so as to ensure that the sealing between the sealing frame 15 and the ice bank body 2 is kept, and ensure that the temperature of the inner cavity of the ice bank body 2 is lower than the temperature of the ice making area.

As can be seen from fig. 8, a sliding shaft is provided on the first side of the door leaf. The sliding shaft is mounted into the first and

second rails

20, 24 such that the first side of the first or second door leaf can slide relative to the first and

second rails

20, 24.

Furthermore, a connecting shaft is arranged on the second side of the door leaf, the connecting shaft is matched with the driving rod 6, and then when the driving rod 6 is driven by the power unit to rotate, the second side of the first door leaf or the second door leaf can also rotate.

In one embodiment, the insulating layer 14 may be made of insulating cotton.

In one embodiment, the door mechanism 7 can be driven by the rotation driving mechanism 3 to swing to open, and after the door mechanism 7 is opened, a first surface of the door mechanism 7 is located outside the guide channel, i.e. facing away from the ice making assembly 4, and is ensured not to contact with the detached ice cubes or water droplets.

It is worth mentioning that the door body mechanism is compact in structure and small in occupied space, and therefore the whole occupied space of the ice storage box is convenient to control.

Wherein, the quantity of door leaf is unrestricted in the door body mechanism. And, the arrangement of the first guide rail assembly is adaptively changed based on the number of door leaves.

In one embodiment, an ice-making system 1 is provided that includes an ice-making assembly 4 and an ice bank disposed on one side of the ice-making assembly 4. For example, an ice bank can be disposed below the ice-making assembly, and ice cubes made by the ice-making assembly 4 can naturally fall into the ice bank under the action of gravity.

Further, the ice making system 1 further includes an ice-water separator 9 disposed between the ice making assembly 4 and the ice bank along the ice falling direction, see fig. 9 and 10.

Wherein, the ice-water separator 9 comprises a material guide component and a water container; along the vertical direction, the peripheral surface of the material guiding component extends downwards in a gradually increasing trend from inside to outside, and the lower edge of the material guiding component extends to the position of a water inlet of the water container; a water guide opening 8 is formed between the lower edge and the water inlet opening.

Further, as can be seen from fig. 9 and 10, the installation position of the water container satisfies: when the door body mechanism 7 is opened, the water container is arranged inside the guide channel.

In this case, the door mechanism 7 can better prevent the ice from scattering.

As can be seen from fig. 11 and 12, the ice making system 1 further includes a water separator 5, a water tank 11, a water pump 12, and the like. When the ice making system 1 works, water in the water tank 11 is pumped into the water distributor 5 through the water pipe 10 under the action of the water pump 12, the water distributor 5 distributes the water uniformly into each interval of the ice making assembly 4, and ice blocks are formed in the intervals of the ice making assembly 4. When ice is removed, the rotary driving mechanism 3 works, the driving rod 6 rotates, and the driven rod 21 rotates along with the driving rod to drive the first door leaf and the second door leaf of the door body mechanism 7 to move, so that the second sides of the first door leaf and the second door leaf rotate, and meanwhile, the first sides of the first door leaf and the second door leaf slide along the first guide rail assembly. Under the combined action of the rotary driving mechanism 3, the driven rod 21 and the first guide rail assembly, the door body mechanism 7 swings to open. A guide channel is formed between the first door leaf and the second door leaf of the door body mechanism 7. In addition, in order to facilitate the ice cubes to fall into the ice storage box, the top end of the guide channel can be connected with the ice shedding outlet of the ice making assembly 4. After ice removal is finished, the rotary driving mechanism 3 moves reversely, the door body mechanism 7 is closed, and the guide channel disappears.

Referring to fig. 13, in an embodiment, a refrigerator is further provided, including the ice making system 1.

In one embodiment, the door mechanism 7 switches between opening and closing by sliding along the rail assembly.

Since a guiding channel is formed between the first door leaf and the second door leaf as the door body mechanism 7 is opened, the guide rail assembly is different from the above-mentioned requirement of the first guide rail assembly. To distinguish from the first track assembly mentioned above, the second track assembly is named.

The second guide rail assembly is fixed relative to the ice storage box body and comprises a third guide rail and a fourth guide rail which are arranged on two sides of the inlet, and the first door leaf and the second door leaf are arranged between the third guide rail and the fourth guide rail and can slide along the extending direction of the third guide rail and the fourth guide rail.

The third guide rail and the fourth guide rail are obliquely arranged relative to the inlet, and further, the door leaves sliding along the third guide rail and the fourth guide rail form a certain angle with each other in an opening state, so that a guide channel is formed between the third guide rail and the fourth guide rail.

In one embodiment, the door mechanism 7 is mounted by means of a hinge.

Specifically, the ice bank further comprises a mounting frame group fixed relative to the ice bank body 2, and the mounting frame group comprises a first mounting frame strip and a second mounting frame strip which are arranged on two sides of the inlet. The first and second door leaves each include a first side that is proximate to each other and a second side that is distal from each other. The second side of the first door leaf is hinged with the first mounting frame strip, and the second side of the second door leaf is hinged with the second mounting frame strip; the first sides of the first door leaf and the second door leaf can both turn towards the direction close to the entrance.

In this case, when the door mechanism 7 is opened, the first surface is located outside the guide passage, and the first surface is prevented from contacting ice or water droplets.

In one embodiment, the set of mounting frames is located outside the ice bank body 2 with a distance from a plane in which the entrance is located. When the door mechanism 7 is opened, the first door leaf and the second door leaf can be at least partially positioned outside the ice storage box, so that the guiding effect of the guiding channel on ice cubes is ensured.

It should be emphasized again that although the door mechanism in the above-mentioned embodiment is in the form of a double door, it does not limit the present invention. The door leaf of the door body mechanism can be any number of three or four.

The above embodiments are merely illustrative of the present invention and are not to be construed as limiting the invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention, and the technical solution of the present invention is covered by the claims of the present invention.
