Generally, when the ice box is a horizontal ice box, the ice making amount of the refrigerator is small due to the limitation of the ice making speed, and the requirement of a user for a large amount of ice cannot be met. Limited by the inner space of the refrigerator, the size of the ice making box cannot be increased at will to improve the ice making quantity.
Disclosure of Invention
An object of the present invention is to provide an ice making method for a rotary centrifugal ice making mechanism capable of reducing an occupied space.
In particular, the present invention provides an ice making method for a rotary centrifugal ice making mechanism including an ice carrying tray extending in an arc shape around a central axis, the ice carrying tray being provided with a plurality of ice recesses for carrying ice making water, the ice recesses opening toward the central axis, the ice making method including the steps of:
driving the ice-carrying tray to rotate around the central axis and making the rotation angular speed of the ice-carrying tray at least greater than the first angular speed;
and injecting ice making water into the ice groove, wherein the rotation angular speed of the ice carrying tray enables the ice making water in the ice groove not to overflow the ice groove.
Further, when the rotation angular speed of the ice carrying tray is the first angular speed and the ice making water in the ice groove is filled, the centrifugal action of the ice making water is just equal to the gravity action of the ice making water.
Further, after the temperature of the ice making water in the ice tank meets a temperature threshold and the refrigeration time of the ice making water meets a time threshold, the default ice making water is condensed into ice blocks.
Further, the temperature threshold is less than or equal to minus 14 degrees centigrade.
Further, the time threshold is equal to or greater than 50 minutes.
Further, the rotary centrifugal ice making mechanism further includes:
the envelope portion surrounds the table wall that deviates from the central axis of carrying the ice dish, and encloses jointly with the table wall that deviates from the central axis of carrying the ice dish and close and form the intake antrum, and the intake antrum communicates with the ice groove to make ice-making water flow into the ice groove by the intake antrum.
Further, the environment of the ice tank is cooled before water is supplied into the ice tank.
Further, the ice making water is injected into the ice tank while the ice making water in the ice tank is condensed.
Furthermore, a filtering part is arranged at the communication part of the ice groove and the water inlet cavity, and the filtering part filters the ice making water in the water inlet cavity when the ice making water flows into the ice groove.
Furthermore, the filtering part is an activated carbon layer.
The ice making method for the rotary centrifugal ice making mechanism utilizes the centrifugal effect generated when the ice carrying tray rotates, so that the ice making water in the ice groove does not separate from the ice carrying tray. The ice making method can make the ice carrying disc be in an arc shape, and the number of the ice grooves arranged on the ice carrying disc is not changed due to the unchanged surface area of the ice carrying disc when the ice carrying disc is in the arc shape, so that the ice making amount of the ice carrying disc is not changed, the space utilization rate of the ice carrying disc is increased, and the whole occupied space of the ice making mechanism is further reduced. In the space with the same size, more ice blocks can be prepared by the ice making method. Meanwhile, when the ice carrying tray is in a working state, ambient cold air is driven to flow, so that the ice making water and the ambient cold air are forced to exchange heat, and the condensation rate of the ice making water is accelerated.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Fig. 1 to 9 show a preferred embodiment of the present invention.
The rotation centrifugal type ice making mechanism in the present embodiment includes an ice carrying tray 100 and a driving device 400. The ice tray 100 extends in an arc shape around a central axis (the ice tray 100 may be regarded as an arc-shaped plate formed by bending a flat plate), one surface of the ice tray 100 is provided with a plurality of ice grooves 110 for loading ice making water, the ice grooves 110 have openings 111, and the openings 111 of the ice grooves 110 face the central axis of the ice tray 100. The ice recesses 110 are arranged in a rectangular array on the development plane of the ice carrying tray 100. That is, when the arc-shaped ice trays 100 are expanded into a flat shape (the ice recesses 110 are expanded together with the ice trays 100 during the expansion), the ice recesses 110 are arranged in a rectangular array on the ice trays 100.
The driving device 400 is used for driving the ice carrying tray 100 to rotate around the central axis, and is configured to drive the ice carrying tray 100 to rotate so that the ice making water in each ice chute 110 does not separate from the ice chute 110 under the centrifugal action. That is, the driving device 400 can drive the ice tray 100 to rotate around the central axis, and the linear velocity of the ice tray 100 when rotating around the central axis is large enough to make the centrifugal action of the ice making water in the ice tray 110 larger than the gravity action thereof, so that the ice making water in the ice tray 110 does not flow out of the ice tray 110 even if the opening 111 of the ice tray 110 faces downward during the rotation with the ice tray 100.
The arc-shaped extension of the ice-bearing tray 100 can reduce the occupied space, and the surface area of the ice-bearing tray 100 is not changed, so that the number of the ice grooves 110 arranged thereon is not changed, and the ice-making amount is not changed, thereby increasing the space utilization rate of the ice-bearing tray 100 and further reducing the occupied space of the whole ice-making mechanism. The ice making mechanism of the present invention can make more ice in the same size space.
It should be noted that the ice tray 110 may be a separate cavity positioned on the ice tray 100, or may be integrally formed with the ice tray 100. The ice chute 110 and the ice tray 100 may be formed by integrally press-molding separate plates or may be formed by integrally injection-molding. The ice groove 110 only needs to have the opening 111 located at one side of the ice-bearing tray 100, that is, the groove body of the ice groove 110 can pass through the ice-bearing tray 100, so that the opening 111 of the ice groove 110 is located at one side of the ice-bearing tray 100, and the groove bottom is located at the other side of the ice-bearing tray 100, and when the above structure is adopted, a part of the side wall 113 of the ice groove 110 extends into the water inlet cavity 310.
In one embodiment, in order to make the ice making water flow back to the ice making grooves 110 by adjusting the water inflow when the ice making water in each ice groove 110 flows out, the opening 111 of the ice groove 110 may be flush with the surface of the ice carrying tray 100 away from the water inlet chamber 310, so that the ice making water in the ice groove 110 may be carried by the ice carrying tray 100 after flowing out of the ice groove 110, and the ice making water on the ice carrying tray 100 may return to the ice groove 110 by controlling the water injection mechanism 500, so that the waste of the ice making water may be reduced, and the ice making water may be prevented from being condensed at other parts of the ice carrying tray 100 to block or make the ice carrying tray 100 be stuck.
In one embodiment, the ice-bearing tray 100 defines a cylindrical chamber, i.e., the ice-bearing tray 100 extends 360 ° around the central axis, such that the space utilization of the ice-bearing tray 100 is maximized. Specifically, the cylindrical chamber defined by the ice-carrying tray 100 may be a cylindrical chamber, and may also be a cylindrical chamber whose cross section perpendicular to the central axis is rectangular or elliptical. Both ends of the columnar chamber of the ice tray 100 along the central axis may be closed or not closed, and when both ends are closed, the ice tray 100 may be provided with an ice outlet 140, and the ice outlet 140 is used for discharging ice cubes condensed in the ice chute 110. When the two ends of the ice cube are not closed, the ice cube can be led out from the two ends of the columnar chamber.
The ice making mechanism further includes an envelope portion 200, the envelope portion 200 surrounds a surface of the ice carrying tray 100 facing away from the opening 111 and forms an inlet cavity 310 together with the surface of the ice carrying tray 100 facing away from the opening 111. That is, when the opening 111 of the ice bank 110 is located at the first side of the ice tray 100, the envelope 200 surrounds the second side of the ice tray 100, and the first side and the second side are opposite surfaces of the ice tray 100. The water injection mechanism 500 is communicated with the water inlet chamber 310 and is used for injecting ice making water into the water inlet chamber 310, and the water inlet chamber 310 is communicated with the ice tank 110, so that the ice making water flowing into the water injection chamber 320 flows to the ice tank 110.
When water needs to be filled into the ice tray 110, water may be filled into the water inlet chamber 310, and the ice-making water flows toward the ice tray 110 through the water inlet chamber 310. The water injection process enables water to be injected into each ice groove 110 evenly, the water injection efficiency is high, and the phenomenon of ice making water leakage is not easy to occur.
In one embodiment, each ice tray 110 may be connected to a water inlet pipe, so that the ice-making water flows directly from the water inlet pipe to the ice tray 110 without passing through the water inlet chamber 310, and the water may be supplied from a single water inlet pipe.
The inlet chamber 310 may be in communication with any portion of the ice bank 110 so that ice-making water can flow into the ice bank 110. In order to prevent the ice-making water in the ice-making tank 110 from being blocked by the condensation of the ice-making water at the communication port between the water inlet chamber 310 and the ice tank 110, in one embodiment, the ice tank 110 has a bottom wall 112 opposite to the opening 111, and the water inlet chamber 310 is communicated with the bottom wall 112. Since the ice making water at the opening 111 of the ice bank 110 is condensed first and the communication port between the water inlet chamber 310 and the ice bank 110 is condensed last, it is possible to prevent the communication port between the water inlet chamber 310 and the ice bank 110 from being blocked by controlling the condensation time.
In order to prevent the ice making water in the ice recess 110 from splashing due to the change of the rotation speed of the ice carrying tray 100, in one embodiment, the first cover plate 130 and the second cover plate 120 for covering both ends of the chamber are disposed in one-to-one correspondence to both ends of the ice carrying tray 100 along the extending direction of the central axis. The first cover 130 and the second cover 120 close both ends of the cylindrical chamber, and ice cubes in the cylindrical chamber are discharged through the ice outlet 140. The cylindrical chamber is relatively closed, so that ice making water in the cylindrical chamber can not splash around due to special conditions. When the first cover 130 and the second cover 120 are disposed, the first cover 130 may be connected to the driving device 400, and particularly, a portion of the first cover 130 coinciding with the central axis may be connected to the rotation shaft of the driving device 400, so that the rotation process of the ice tray 100 may be more stable. In other embodiments, the driving device 400 may also rotate the ice carrying tray 100 by driving the envelope 200.
When the first cover plate 130 and the second cover plate 120 are disposed at two ends of the cylindrical chamber, in one embodiment, as shown in fig. 5 to 7, the enveloping part 200 surrounds the surface walls of the first cover plate 130 and the second cover plate 120 that are away from the cylindrical chamber, and encloses the water injection cavity 320 with the surface walls of the first cover plate 130 and the second cover plate 120 that are away from the cylindrical chamber (i.e., the space between the enveloping part 200 and the first cover plate 130 and the space between the enveloping part 200 and the second cover plate 120 become the water injection cavity 320), and the water injection cavity 320 is communicated with the water inlet cavity 310. Both the water injection chamber 320 and the water inlet chamber 310 may be completely communicated with the structure shown in fig. 1 or 5, or may be communicated with each other by using a pipe. When the envelope 200 has the above structure, the envelope 200, the first cover 130, the second cover 120, the ice trays 100, and the ice recesses 110 are combined together to form a rotating part as shown in fig. 7. The inlet chamber 310 and the injection chamber 320 are combined together to form a sealed chamber.
As shown in fig. 1 or 5, the envelope portion 200 includes a first envelope wall 220 perpendicular to the central axis, the first envelope wall 220 is spaced apart from the first cover 130, the driving device 400 is connected to the first envelope wall 220, and a portion of the first cover 130 coinciding with the central axis may be connected to a rotating shaft of the driving device 400, so that the rotation process of the ice-bearing tray 100 may be more smooth. Further, the envelope part 200 further includes a second envelope wall 210 perpendicular to the central axis, the second envelope wall 210 is spaced apart from the second cover plate 120, a circular water injection hole is formed at an intersection of the second envelope wall 210 and the central axis, and the water injection mechanism 500 is communicated with the water injection hole, since the water injection hole rotates around the center thereof when the second envelope wall 210 rotates, the water injection mechanism 500 injects ice water into the water injection hole so that the water injection mechanism 500 does not rotate with the second envelope wall 210, so that the water injection mechanism 500 can be more easily positioned.
In one embodiment, as shown in fig. 2, an extension pipe 211 is connected outside the water injection hole, and the length direction of the extension pipe 211 is parallel to the central axis. The water injection mechanism 500 includes a connection pipe 510, the connection pipe 510 passing through the extension pipe 211, and having one end passing through the water injection hole and extending into the water injection chamber 320 and the other end communicating with an external water inlet pipe. When the second enveloping wall 210 rotates, the extension pipe 211 rotates together with it, and at this time, the extension pipe 211 rotates relative to the connection pipe 510, and the ice making water in the water filling chamber 320 can be effectively prevented from leaking out of the water filling hole by adapting the pipe diameters of the connection pipe 510 and the extension pipe 211. Further, an edge of the connection tube 510, which extends into one end of the sealed chamber, is formed with a first sealing flange 511 extending outward, the first sealing flange 511 abutting against an inner wall surface of the first envelope wall 220 facing the sealed chamber. The first sealing flange 511 may effectively prevent the ice-making water in the water filling chamber 320 from overflowing into a gap between the extension pipe 211 and the connection pipe 510.
A second sealing flange 212 is formed at one end of the extension pipe 211 far away from the water injection hole, an annular first abutting ring 512 is arranged on the outer wall surface of the connection pipe 510, and the first abutting ring 512 abuts against the surface of the second sealing flange 212 far away from the water injection hole. The abutment of the first abutment ring 512 and the second sealing flange 212 may make it difficult for ice-making water leaked between the extension pipe 211 and the connection pipe 510 to continue to leak.
In one embodiment, to further enhance the sealing between the water injection mechanism 500 and the rotating part, the outer diameter of the first abutting ring 512 is greater than or equal to the outer diameter of the second sealing flange 212, the outer edge of the first abutting ring 512 is connected to the second abutting ring 513, the second abutting ring 513 extends inwards from the outer edge of the first abutting ring 512 around the outer edge of the second sealing flange 212, and the second abutting ring 513 abuts against the surface of the second sealing flange 212 facing the water injection hole. Such that when the rotary part rotates, the second sealing flange 212 rotates in the gap between the first and second abutment rings 512, 513. Further, in order to increase the length of the leakage path of the leaked ice making water, the surface of the second sealing flange 212 facing away from the water injection hole is provided with an annular protrusion 213 extending around the central axis, the first abutment ring 512 is formed with an annular hole to be fitted with the annular protrusion 213, the surface of the second sealing flange 212 facing the water injection hole is provided with an annular protrusion 213 extending around the central axis, and the second abutment ring 513 is formed with an annular hole to be fitted with the annular protrusion 213. The annular projection 213 is fitted in the annular hole, and when the rotary part rotates, the annular projection 213 rotates relative to the annular hole.
When the extension pipe 211 rotates relative to the connection pipe 510, a slight sliding friction is generated between the connection pipe 510 and the extension pipe 211, so that the connection pipe 510 receives a torque generated by a friction force, and in order to prevent the connection pipe 510 from rotating due to the torque, in an embodiment, as shown in fig. 4, the connection pipe 510 includes a positioning portion 514, and the positioning portion 514 is a rectangular pipe (i.e., the connection pipe 510 has at least one section of pipe with a rectangular shape, the connection pipe 510 may also have a rectangular shape as a whole, and an internal channel of the positioning portion 514 for guiding the ice making water may have a rectangular shape or a circular shape). The ice making mechanism further includes a bracket 520 for positioning the water filling mechanism 500, the bracket 520 is formed with a rectangular hole 521 for positioning the positioning part 514, the positioning part 514 cannot rotate in the rectangular hole 521 when the positioning part 514 is positioned in the rectangular hole 521, and the bracket 520 is positioned on a relatively fixed platform (if the ice making mechanism is disposed in a refrigerator, the bracket 520 may be positioned on a housing of the refrigerator), so that the bracket 520 may effectively prevent the connecting pipe 510 from rotating.
Since the connection tube 510 has a special structure, in order to facilitate the assembly with the extension tube 211, in one embodiment, the connection tube 510 is made of a flexible material such as rubber, which can be removed by force, for example, the connection tube 510 may be made of TPE. The outer water tube connected to the connection tube 510 may be made of LDPE or LLDPE, and the annular protrusion 213 on the second annular flange may be made of a material capable of reducing sliding friction, such as PA or POM.
In one embodiment, a filter part 114 for filtering ice making water flowing into the ice tank 110 is disposed at a communication position of the water inlet chamber 310 and the ice tank 110, and the filter part 114 is used for filtering small particles or foreign substances capable of generating odor in the ice making water flowing into the ice tank 110. When the inlet chamber 310 communicates with the bottom wall 112 of the ice bank 110, the filter part 114 is disposed at the bottom wall 112 of the ice bank 110, and particularly, the filter part 114 may be an activated carbon layer. The filter unit 114 is disposed in the ice making mechanism to save an external filter, for example, when the ice making mechanism is disposed in a refrigerator, the refrigerator does not need to separately add a filter, so that a space occupied by the filter can be saved.
A second aspect of the present invention also provides a refrigerator including the ice making mechanism in any of the above embodiments. Wherein the bracket 520 of the ice-making mechanism is secured within the housing of the refrigerator in the refrigerated environment of the refrigerator.
The third aspect of the present invention also provides an ice making method for a rotary centrifugal ice making mechanism, which is used for the rotary centrifugal ice making mechanism in any of the above embodiments. As shown in fig. 8, the ice making method includes the steps of:
s101: driving the ice-bearing tray 100 to rotate about the central axis and making the rotational angular speed of the ice-bearing tray 100 at least greater than the first angular speed;
s103: ice making water is injected into the ice chute 110, and the rotation angular velocity of the ice tray 100 is set such that the ice making water in the ice chute 110 does not overflow the ice chute 110.
That is, in the ice making process, the ice making water in the ice tray 110 is not separated from the ice tray 100 by the centrifugal force generated when the ice tray 100 rotates. Since the ice making method can make the ice tray 100 in an arc shape, and the surface area of the ice tray 100 is not changed when the ice tray 100 is in the arc shape, the number of the ice grooves 110 arranged thereon is not changed, so that the ice making amount of the ice tray 100 is not changed, thereby increasing the space utilization rate of the ice tray 100 and further reducing the overall occupied space of the ice making mechanism. In the space with the same size, more ice blocks can be prepared by the ice making method.
The first angular velocity is expressed as a minimum angular velocity value of the ice-carrying tray 100 when making ice, and the rotational speed of the ice-carrying tray 100 when making ice is constant and at least greater than the first angular velocity. The first angular velocity is determined according to actual requirements, and in one embodiment, when the rotational angular velocity of the ice tray 100 is the first angular velocity and the ice making water in the ice tank 110 is filled, the centrifugal action of the ice making water is equal to the gravity action of the ice making water. Of course, in other embodiments, the value of the first angular velocity may be increased as appropriate.
In order to determine whether the ice making water in the ice tank 110 has completely condensed into ice cubes, in one embodiment, a temperature sensor may be provided for detecting the temperature of the ice tank 110. Further, the condensation time of the ice making water in the ice tank 110 may be counted, and when the temperature of the portion of the ice tank 110 reaches the preset temperature threshold and the condensation time of the ice making water is greater than the preset temperature threshold, it may be determined that the ice making water is completely condensed into ice blocks, and at this time, the ice making water in the ice tank 110 may be led out. Specifically, the temperature threshold may be less than or equal to-14 degrees celsius, such as-14 degrees celsius, 16 degrees celsius, or the like. The time threshold may be greater than or equal to 50 minutes, such as 50 minutes, 60 minutes, 70 minutes, and the like.
In one embodiment, when water is injected into the ice recesses 110, the water pipes located at the central axis may be used to directly supply water to the rotating ice recesses 110, and the ice-making water flowing out of the water pipes may be picked up by the rotating ice recesses 110 due to centrifugal force. In order to make the water inlet effect better, in another embodiment, the ice making mechanism further includes an envelope portion 200, the envelope portion 200 surrounds a surface wall of the ice carrying tray 100 that is away from the central axis, and forms a water inlet cavity 310 together with the surface wall of the ice carrying tray 100 that is away from the central axis, and the water inlet cavity 310 is communicated with the ice chute 110, so that the ice making water flows into the ice chute 110 from the water inlet cavity 310. That is, as shown in fig. 1, water in the ice recess 110 is supplied from the water inlet chamber 310 rotating together with the ice tray 100, so that the ice making water is not splashed during the water supply to the ice recess 110 and is not easily wasted. It should be noted that, during the process of filling the ice tank 110 with water from the inlet chamber 310, the water in the ice tank 110 tends to flow back into the inlet chamber 310 due to the centrifugal effect, so that the ice-making water in the inlet chamber 310 needs to be introduced into the ice tank 110 by applying a proper pressure to the inlet chamber 310, and the ice-making water in the ice tank 110 may flow back into the inlet chamber 310 when the water pressure in the inlet chamber 310 is insufficient.
In the ice making process, each ice tank 110 may be filled with a predetermined amount of ice making water (the amount of ice making water required to make a single ice block), and then the ice tank 110 is cooled, so that the ice making water in the ice tank 110 is entirely condensed into ice. However, this condensation process makes the ice stick to the surface wall of the ice chute 110 after the ice is formed and is not easy to remove. When the ice cubes are stuck to the ice chute 110, a heating means is additionally added to melt a portion of the ice cubes contacting the ice chute 110 in order to facilitate the ice taking. In order to facilitate the removal of ice cubes, in one embodiment, the environment in which ice tank 110 is located may be cooled before water is supplied into ice tank 110 (indicating that ice tank 110 is in a cooled state before water is supplied, ice tank 110 may be always in a relatively low temperature environment, or the environment in which ice tank 110 is located may be cooled before water is supplied into ice tank 110, and the cooled state indicates that the temperature is reduced to a state in which water can be condensed into ice cubes).
When the ice tank 110 is in a low temperature environment, the ice making water in the ice tank 110 is frozen and the ice making water is injected into the ice tank 110. Namely, the ice making water is slowly supplied to the ice tank 110 in the environment with a low temperature, the ice making water entering the ice tank 110 starts to condense after contacting with the cold air, and the condensed ice is pushed outwards by the ice making water in the water inlet chamber 310 while condensing, so that the condensed ice is in a motion state and is difficult to adhere to the inner wall surface of the ice tank 110, and the defect that the formed ice cannot be separated from the ice tank 110 is well solved. Specifically, the water inflow rate into the ice bank 110 can be controlled by controlling the water pressure in the water inlet chamber 310.
Further, a filter part 114 is provided at a communication part between the ice tank 110 and the water inlet chamber 310, and the ice making water in the water inlet chamber 310 is filtered by the filter part 114 when flowing into the ice tank 110, specifically, the filter part 114 is an activated carbon layer. The ice making water in the inlet chamber 310 permeates the activated carbon layer and is then injected into the ice tank 110, thereby filtering the ice making water guided into the ice tank 110.
Specifically, the above-mentioned entire ice making method comprises the following specific steps:
s201: the ice tank 110 may be in a temperature-reduced environment (an environment in which ice-making water can be condensed into ice cubes) before water is supplied to the ice tank 110, specifically, the ice tank 110 may be continuously in the temperature-reduced environment, or the temperature of the environment in which the ice tank 110 is located may be reduced to the temperature-reduced environment before water is supplied to the ice tank 110.
S203: the ice-bearing tray 100 is driven to rotate about the central axis such that the rotational angular speed of the ice-bearing tray 100 is higher than the first angular speed.
S205: the ice making water in the water inlet chamber 310 is filtered by the filter unit 114 and then guided into the ice tank 110, so that the ice making water entering the ice tank 110 is condensed and the water is continuously supplied into the ice tank 110 until the ice making water in the ice tank 110 reaches a predetermined amount.
S207: it is determined whether the temperature of the ice making water reaches the temperature threshold value, and it is determined whether the time from the start of the injection of the ice making water into the ice bath 110 to the current time reaches the time threshold value.
S209: when the temperature of the ice making water exceeds the temperature threshold and the ice making time exceeds the time threshold, the ice making water is completely condensed into ice blocks by default, the ice carrying tray 100 stops rotating, and the ice blocks are led out.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
