The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.

Referring to fig. 1 to 11, a refrigerating apparatus 100 according to an embodiment of the present invention is described below.

As shown in fig. 2 and 7, a refrigeration apparatus 100 according to an embodiment of the present invention includes: the refrigerator comprises a refrigerator body 10, a refrigerator door 20 and an ice chest assembly 30.

The box body 10 is provided with a refrigerating cavity 10a and an opening 10b communicated with the refrigerating cavity 10a, an air duct 110 for conveying cold air is arranged in the refrigerating cavity 10a, and an air outlet 110a which is arranged close to the top wall of the refrigerating cavity 10a is arranged on the air duct 110 so as to drive the cold energy to flow towards the opening 10b along the top wall of the refrigerating cavity 10 a; a door 20 provided on the case 10 to open or close the opening 10b; the ice bank assembly 30 includes a plurality of ice trays 330, and the ice trays 330 are arranged in a stepped manner in a direction approaching the air outlet 110 a.

It can be understood that, as shown in fig. 2 and 7 (the arrows point to the flowing direction of the cold energy in the drawing), when the air duct 110 of the refrigeration device 100 conveys the cold energy into the refrigeration cavity 10a, by arranging the air outlet 110a close to the top wall of the refrigeration cavity 10a, when the cold energy flows out from the air outlet 110a, the cold energy can flow to the opening 10b along the top wall surface of the refrigeration cavity 10a by using the coanda effect, and the air duct has a simple structure, a relatively small number and no need of arranging a complex air duct structure. When the cold air flows to the ice box assembly 30, the ice grids 330 are arranged in a step manner to match the flow direction of the air flow, so that the cold air is conveyed more uniformly, and the ice making effect and the ice making efficiency are improved.

It should be noted that, the number of the air outlets 110a of the air duct 110 is not limited to one, and may be plural, one of which is disposed near the top wall of the cooling chamber 10a, and the other air outlets 110a are used for delivering part of the cooling capacity into the cooling chamber 10a, so as to cool the interior of the cooling chamber 10 a.

According to the refrigeration equipment 100 of the embodiment of the invention, by arranging the air duct 110 with the air outlet 110a close to the top wall of the refrigeration cavity 10a, the air outlet 110a conveys cold energy towards the opening 10b, and arranging the ice grids 330 in a step arrangement, the distribution of the ice grids 330 can be more consistent with the airflow direction, the cold air reaching the ice box assembly 30 is more uniform, the internal air duct 110 is ensured to have a simple structure, the cost is reduced, the cold energy is uniformly distributed around the ice grids 330, the refrigeration effect is improved, and the refrigeration efficiency is improved.

In some embodiments of the present invention, as shown in fig. 1, 2, and 7, in any two adjacent ice trays 330, the orthographic projection of the ice tray 330 located above and the orthographic projection of the ice tray 330 located below overlap (the orthographic projection may refer to a projection on a perpendicular horizontal plane). That is, the two adjacent ice trays 330 are arranged in a step, and the positions of the two adjacent ice trays 330 are distributed more closely. The overlapping position distribution of the orthographic projection can effectively reduce the width of the ice box 310, increase the available volume in the box 10, and simultaneously help to match the flow of the cold energy among the ice grids 330, so that the cold energy can be uniformly distributed among a plurality of ice grids 330, and the full utilization of the cold energy is realized.

In some embodiments of the present invention, the orthographic projection of the upper ice tray 330 and the orthographic projection of the lower ice tray 330 do not overlap in any adjacent two ice trays 330. That is, the two adjacent ice grids 330 are arranged in a step manner and the orthographic projections are not overlapped, and the position distribution can be helpful for the flow of the cold energy between the ice grids 330, so that the periphery of the two adjacent ice grids 330 is uniformly distributed with sufficient cold energy, the full utilization of the cold energy is realized, and the refrigerating effect is improved.

In some embodiments of the present invention, as shown in fig. 1, an ice storage groove 331 is formed on each ice tray 330, and in any two adjacent ice trays 330, a water outlet 330a communicating with the ice storage groove 331 is formed on the ice tray 330 located above. That is, the water in the ice storage groove 331 of the upper ice tray 330 can flow into the lower ice tray 330 through the water outlet 330a. When the ice storage groove 331 in the ice tray 330 positioned above is full of water, excessive water flows into the ice storage groove 331 of the adjacent ice tray 330 below through the water outlet 330a, so that the function of filling water into all the ice trays 330 by injecting water into only one ice tray 330 is realized, the water injection structure of the ice box assembly 30 is simplified, the use of the ice box assembly 30 of the refrigeration equipment 100 is more convenient, and the use experience of a user is improved.

In some embodiments of the present invention, the orthographic projection of the water outlet 330a is located in the orthographic projection of the ice tray 330 below, which is understood to ensure that when the water flow in the ice tray 330 above flows into the ice tray 330 adjacent below through the water outlet 330a, no water flow is ensured to flow outside the ice tray 330. In some embodiments of the present invention, as shown in fig. 1, the ice storage tank 331 includes a plurality of sub-tanks 3311, and a through hole 330b is provided between any adjacent two sub-tanks 3311. That is, the ice storage grooves 331 in the same ice tray 330 communicate with each other, and the water flow in the partial grooves 3311 can flow from one partial groove 3311 to another partial groove 3311. When water is injected into one of the sub-tanks 3311 located in the ice storage tank 331 of the uppermost ice tray 330 and the water of one sub-tank 3311 is filled, the excessive water flows into the other sub-tanks 3311 of the ice storage tanks 331 in the ice tray 330 through the through holes 330b between the sub-tanks 3311 until all the sub-tanks 3311 of the ice storage tank 331 of the entire ice tray 330 can be filled with water, and the excessive water flows into the ice storage tank 331 of the ice tray 330 adjacent below through the water outlet holes 330a.

As can be seen from this, the through holes 330b are provided in the sub-tank 3311 of the ice storage tank 331, so that water can be injected into only one sub-tank 3311 positioned in the uppermost Fang Bingge ice storage tank 331, and all the ice storage tanks 331 of all the ice trays 330 in the ice bin 310 can be filled with water. Through set up through-hole 330b between the branch groove 3311 of ice storage groove 331, make the water injection of ice chest 310 more simple and convenient, promoted user's use experience, can not cause harmful effect to refrigerating mechanism's ice making effect simultaneously.

In some embodiments of the present invention, as shown in fig. 2-11, the ice bin assembly 30 further includes: the ice box 310 and the box cover 320, the ice box 310 is arranged on the box door 20, and a plurality of ice trays 330 are arranged in the ice box 310; the cover 320 is provided on the opening of the ice bank 310, the cover 320 is provided on the ice bank 310, and the cover 320 is configured such that the cover 320 opens the ice bank 310 when the door 20 closes the opening 10b.

Specifically, by providing the air outlet 110a near the top wall of the cooling chamber 10a on the air duct 110, the cooling capacity is driven to flow along the top wall of the cooling chamber 10a towards the direction of the opening 10b, so as to ensure that enough cooling capacity flows into the ice bin 310; meanwhile, in order to ensure that the cold entering the ice bank 310 is not spread to the outside after the door 20 is opened, the cover 320 closes the ice bank 310 when the door 20 is opened, so that the cold entering the ice bank 310 is not spread to the external environment through heat conduction, thereby ensuring the ice making effect of the refrigeration apparatus 100; when the door 20 is closed, the cover 320 of the ice bank 310 is opened, so that the cold in the refrigerating chamber 10a flows toward the ice bank 310 along the top wall of the refrigerating chamber 10a, and at the same time, the opened cover 320 serves as a guide plate to guide the cold into the ice bank 310.

In some embodiments of the present invention, as shown in fig. 10, a top opening 310a is provided at the top of the ice bank 310, and the bank cover 320 includes a plurality of blades 321, the plurality of blades 321 being pivotably provided in the top opening 310 a. In order to prevent the cold in the ice bin 310 from being spread out to the outside environment through the opening 10b when the door 20 of the box 10 is opened, the box cover 320 is linked with the door 20 and the box 10, and the box cover 320 is matched with the top opening 310a when the door 20 is opened, the box cover 320 can completely close the top opening 310a at the top of the ice bin 310, so that the leakage of the cold is reduced.

In some embodiments of the present invention, as shown in fig. 7 to 9, a top opening 310a is provided at the top of the ice bank 310, a rear opening 310b is provided at an end of the ice bank 310 facing the rear wall of the cooling chamber 10a, and the cover 320 includes a plurality of blades 321, one part of the plurality of blades 321 being pivotably provided in the top opening 310a, and the other part being pivotably provided in the rear opening 310 b. That is, on the basis of providing the top opening 310a, the heat exchange area of the ice bin 310 can be increased by additionally providing the rear opening 310b, so that the contact area between the interior of the ice bin 310 and the cold energy can be increased, more cold energy can be more easily introduced into the interior of the ice bin 310, and the ice making speed in the ice bin 310 can be increased.

Specifically, as shown in fig. 8 and 9, when the door 20 of the case 10 is opened, the plurality of blades 321 at the top opening 310a and the rear opening 310b of the ice bank 310 are rotated, and the plurality of blades 321 are engaged with each other to completely cover the opening of the ice bank 310, i.e., close the ice bank 310, thereby reducing the cold energy flowing into the inside of the ice bank 310 from being outwardly diffused into the external environment through the opening 10b; when the door 20 of the case 10 is closed, the plurality of blades 321, which are positioned at the top opening 310a and the rear opening 310b of the ice bank 310 and cooperate with each other, rotate to open the closed ice bank 310, and cool air enters the interior of the ice bank 310 through the top opening 310a and the rear opening 310b of the ice bank 310 along the top wall of the refrigerating chamber 10a, thereby providing cool air to the ice bank 310 and accelerating the ice making speed of the ice bank 310.

In some embodiments of the present invention, as shown in fig. 8 and 9, the plurality of blades 321 are coupled to the movement of the case 10 to allow the case 10 to trigger the plurality of blades 321 to rotate when the door 20 closes the opening 10b. Specifically, when the door 20 is closed, the case 10 triggers the plurality of blades 321 to move, so that the opening of the ice bin 310 is opened, and the cold energy driven by the air duct 110 flows into the ice bin 310 along the top wall of the refrigerating chamber 10a, so that the ice bin 310 is filled with the cold energy, and the ice making speed is increased; when the door 20 is opened, the case 10 can trigger the plurality of blades 321 to move, so that the opening of the ice bank 310 is closed, the amount of cold which is outwardly diffused to the external environment through the opening 10b is reduced, and the consumption of energy is reduced.

For example, a gear is provided on a rotation shaft of each blade 321, a rack is provided on the case 10, and when the door 20 closes the opening 10b, the rack may be engaged with the gears on the plurality of blades 321, thereby driving the plurality of blades 321 to rotate, and opening the ice bank 310. For another example, a friction wheel is provided on the rotation shaft of each blade 321, and a contact plate is provided on the case 10, and when the contact plate is engaged with the friction wheel, the friction wheels are also driven to rotate, so that the ice bank 310 is opened.

In some embodiments of the present invention, the ice bank assembly 30 further includes a driving member (not shown) that moves the plurality of blades 321 in conjunction to drive the plurality of blades 321 to rotate.

Specifically, the driving member may be one of a motor, an electric push rod, and a cylinder, and the driving member may be a device for powering the rotation of the blade 321. The driving member is installed on the ice bank 310 to be coupled with the plurality of blades 321, and simultaneously, to be coupled with the movement of the case 10. When the door 20 is opened or closed, the case 10 triggers the driving member to move, thereby driving the plurality of blades 321 to rotate, closing or opening the ice bank 310.

The linkage of the driving member and the plurality of blades 321 may be that the driving member and each blade 321 perform separate linkage, and movements between the blades 321 and the blades 321 do not interfere with each other, and each blade 321 may perform separate movements. The mode of independent linkage of the driving piece and each blade 321 can control the rotation angle of each blade 321 more finely, and then suitable diversion angles are independently arranged for each blade 321, so that the overall diversion effect of the ice box assembly 30 is improved, and the ice making effect of the refrigeration equipment 100 and the performance quality of the refrigeration equipment 100 are further improved.

For example, the driving member is an electric push rod, a rack is arranged on a telescopic rod of the electric push rod, a gear is arranged on a rotating shaft of each blade 321, the telescopic rod of the electric push rod stretches to drive the rack to be matched with the gear, and the plurality of blades 321 are driven to rotate to open the ice box 310.

The linkage of the driving piece and the plurality of blades 321 can be that the driving piece is linked with any one blade 321 in the plurality of blades 321, the adjacent blades 321 of the plurality of blades 321 are linked with each other, the plurality of blades 321 form a whole, each blade 321 can not move independently, and the driving piece drives one blade 321 to drive the plurality of blades 321. The mode of linkage of the driving piece and one of the blades 321 has simple structure, fixed movement mode, convenient installation and maintenance, and reduces the production cost while not affecting the ice making effect.

For example, the rotation shafts of the plurality of blades 321 are engaged with each other through gears, the driving member is a motor, and is connected to the gear on the rotation shaft of one of the blades 321, and the motor is started to drive the plurality of blades 321 to rotate, thereby opening or closing the ice bank 310.

In addition, the driving member not only is linked with the plurality of blades 321, but also can be linked with the plurality of blades 321, and even each blade 321 is driven by one driving member. The plurality of driving members are linked with the plurality of blades 321 to enable finer control of the blades 321. For example, the driving member is an electric push rod, a rack is arranged on a telescopic rod of the electric push rod, a gear is arranged on a shaft of the plurality of blades 321, and when the electric push rod stretches, the rack can be meshed with the gear on the plurality of blades 321, so that the plurality of blades 321 are driven to rotate.

In view of the comprehensive consideration of the various aspects of the overall driving effect, the volume limitation of the apparatus, the convenience of installation, and the like, two driving members may be installed on the case 10, wherein a first driving member is coupled to the blade 321 located at the top opening 310a, and a second driving member is coupled to the blade 321 located at the rear opening 310 b.

In some embodiments of the present invention, as shown in fig. 5 and 6, a top opening 310a is provided at the top of the ice bank 310, and a cap 320 includes: the first cover 322 is rotatably connected to an end portion of the ice bin 310 near the bin door 20, the first cover 322 is fitted over the top opening 310a, the first cover 322 is rotatable when driven, and the second cover 323 is provided on the first cover 322 and may form a first angle with the first cover 322 to guide the cold energy to flow into the ice bin 310 along the second cover 323.

That is, the first cover 322 may be connected to the door 20 or the ice bank 310, the second cover 323 is connected to the first cover 322, and the first cover 322 is correspondingly matched with the top opening 310a provided on the ice bank 310. When the door 20 is opened, the first cover 322 cooperates with the top opening 310a of the ice bank 310 to seal the ice bank 310, thereby reducing the outflow of the cold in the ice bank 310; when the door 20 is closed, the first cover 322 and the second cover 323 move away from the ice bank 310 toward the top wall of the cooling chamber 10a, so that the top opening 310a of the ice bank 310 is opened, and the cooling energy driven by the air duct 110 flows into the ice bank 310 from the top opening 310 a.

In some embodiments of the present invention, as shown in fig. 3 and 4, the end of the ice bank 310 facing the rear wall of the cooling chamber 10a is provided with a rear opening 310b, and the second cover 323 is adapted to be fitted over the rear opening 310 b. Referring to the foregoing, on the basis of providing the top opening 310a, the heat exchange area of the ice box 310 can be increased by additionally providing the rear opening 310b, so as to increase the contact area between the interior of the ice box 310 and the cold energy, so that more cold energy can more easily enter the interior of the ice box 310, and the ice making speed in the ice box 310 can be increased. In this case, when the door 20 is opened, the first cover 322 is engaged with the top opening 310a, and the second cover 323 is engaged with the rear opening 310b, both of which seal the ice bank 310, reducing outflow of cold in the ice bank 310; when the door 20 is closed, the first cover 322 and the second cover 323 move away from the ice bin 310 toward the top wall of the cooling chamber 10a, so that the top opening 310a of the ice bin 310 is opened, and the second cover 323 acts as a deflector, so that the cooling energy driven by the air duct 110 flows into the ice bin 310 from the top opening 310a and the rear opening 310 b.

In some embodiments of the present invention, the second cover 323 is pivotally provided on the first cover 322, and the second cover 323 may abut against the top wall of the cooling chamber 10a and rotate the second cover 323 relative to the second cover 323 to guide the cooling energy to flow along the second cover 323 to the ice bank 310.

Specifically, as shown in fig. 3 and 4, the second cover 323 is provided with a driven portion 3231 and a guide portion 3232, the second cover 323 is pivotally connected to the first cover 322, and the first cover 322 moves in conjunction with the door 20. When the door 20 moves towards the opening 10b, the first cover 322 drives the second cover 323 to rotate towards the top wall of the refrigerating cavity 10a, and when the driven part 3231 of the second cover 323 abuts against the top wall of the refrigerating cavity 10a, the driven part 3231 drives the second cover 323 to rotate clockwise relative to the first cover 322 through interaction with the top wall of the refrigerating cavity 10a, and the rotating direction is the direction that the flow guiding part 3232 approaches the first cover 322, and at the moment, the flow guiding part 3232 rotates towards one side of the opening 10b, so that the flow guiding effect can be achieved.
