DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2As shown, the first embodiment of the present invention is an ice-making device, comprising an ice-making tray 1 and a support frame 2 arranged outside the ice-making tray 1, and also comprising an ice-removing mechanism, wherein the ice-making tray 1 comprises an ice-making bottom plate 101 fixedly connected to the support frame 2, and the ice-making bottom plate 101 is fixedly mounted with a plurality of longitudinal ice-making plates 102 arranged in a vertical direction and parallel to each other and a plurality of transverse ice-making plates 103 arranged perpendicular to the longitudinal ice-making plates 102, wherein a plurality of rectangular ice grids are formed between the transverse ice-making plates 103 and the longitudinal ice-making plates 102, and the ice-removing mechanism comprises one or more push rods 3 extending into the interior of the ice grid, and an ice-removing hole 4 matching the push rod 3 is provided on the ice-making bottom plate 101, so as to enable the push rod 3 to pass through the ice-removing hole 4 to apply a force to the ice cubes formed in the ice grid to make them move away from the ice-making bottom plate 101, and the transverse ice-making plates 103 are automatically connected to the ice-making bottom plate 10 1 is connected to the ice-making bottom plate 101 and extends downwardly in an inclined direction away from the ice-making bottom plate 101. A first inclined angle α is formed between the transverse ice-making plate 103 and the ice-making bottom plate 101. The first inclined angle is an acute angle, and 88°≥α≥83°. The ice-making device in this embodiment improves the ice-shedding efficiency under the action of the ice-shedding mechanism, and the ice cubes made are of high quality. By setting the transverse ice-making plate 103 to a structure that extends downwardly in an inclined direction away from the ice-making bottom plate 101 from the connection with the ice-making bottom plate 101, the vertical downward gravity of the ice cubes themselves will generate a gravity component along the inclined direction of the transverse ice-making plate 103. Under the same heating power, the heating and melting time can be reduced, so that the ice cubes can be smoothly separated from the ice tray under the action of their own gravity component and the ice-shedding mechanism. The setting of the first inclined angle α further improves the ice-shedding efficiency; and at the first inclined angle, no whitening or gaps will occur, and the ice cubes are of high quality.

[0030] like Figure 3 As shown, the ice tray 1 further includes a transverse baffle 7 fixedly mounted on opposite side walls of the support frame 2, the transverse baffle 7 is fixedly connected to the plurality of longitudinal ice-making plates 102 and the ice-making bottom plate 101, and the ice tray 1 further includes a longitudinal baffle fixedly mounted on the other opposite side walls of the support frame 2, the longitudinal baffle is fixedly connected to the plurality of transverse ice-making plates 103 and the ice-making bottom plate 101. The transverse ice-making plates 103 and the longitudinal ice-making plates 102 have the same height of d1, and the transverse baffle 7 and the longitudinal baffle have the same height of d2, and d2>d1. By setting the transverse baffle 7 and the longitudinal baffle to be wider than the longitudinal ice-making plates 102 and the transverse ice-making plates 103, it can be ensured that the ice cubes in all the ice trays can be connected together, and when the push rod 3 performs the ice-pushing operation, all the ice cubes can be pushed to fall off at the same time, thereby improving the ice-making efficiency.

[0031] Preferably, the push rod 3 is connected to a driving mechanism, which is used to drive one or more push rods 3 to penetrate the ice-removing hole 4; the propulsion direction of the push rod 3 extends downwardly in a direction away from the ice-making bottom plate 101, and a second inclination angle β is formed between the propulsion direction of the push rod 3 and the ice-making bottom plate 101.

[0032] Preferably, the second inclination angle is the same as the first inclination angle, and the pushing direction of the push rod 3 is parallel to the transverse ice-making plate 103. The pushing direction is the same as the extension direction of the transverse ice-making plate 103, so that the push rod 3 will not damage the ice cubes when pushing the ice cubes in the ice tray. Since there is no dispersion of forces in other directions, the thrust is all concentrated in the direction consistent with the sliding direction of the ice cubes, and at this time, it can also be ensured that the minimum thrust is used to push the ice cubes.

[0033] Preferably, it also includes a water supply assembly 6 arranged above the support frame 2 and a conduit assembly 5 arranged on the ice-making bottom plate 101 away from the side of the transverse ice-making plate 103 and the longitudinal ice-making plate 102, wherein the water supply assembly 6 is used to supply water to the ice-making tray 1, and the ice-making bottom plate 101 and the conduit assembly 5 are both made of heat-conducting materials. The water supply assembly 6 is used to provide a water flow that flows vertically from top to bottom, and one end of the water supply assembly 6 is connected to a water supply inlet 601 for connecting to an external water supply pipe.

[0034] like Figure 4 As shown, the conduit assembly 5 includes a plurality of copper tubes 501 arranged in a serpentine shape and a water inlet section 502 and a water outlet section 503 installed at both ends of the copper tubes 501. The conduit assembly 5 is used to introduce a cold medium or a hot medium from the water inlet section 502 into the copper tubes 501. After the cold medium or the hot medium circulates in the copper tubes 501 for one cycle, the cold medium or the hot medium transfers the cold or heat to the ice tray 1 and is discharged from the water outlet section 503.

[0035] A second embodiment of the present invention is an ice-making method, which provides an ice-making device, the ice-making device comprising an ice-making tray 1 and an ice-removing mechanism, the ice-making tray 1 comprising an ice-making bottom plate 101 and a plurality of transverse ice-making plates 103 and a longitudinal ice-making plates 102 fixedly mounted on the ice-making bottom plate 101, the plurality of transverse ice-making plates 103 and the longitudinal ice-making plates 102 are arranged perpendicular to each other, and a plurality of rectangular ice grids are formed between the plurality of transverse ice-making plates 103 and the longitudinal ice-making plates 102, the ice-removing mechanism comprising one or more push rods 3 extending into the interior of the ice grid, the ice-making bottom plate 101 is provided with an ice-removing hole 4 matching the push rod 3, the ice-removing mechanism is used to make the push rod 3 pass through the ice-removing hole 4 to apply a force to the ice cubes in the ice grid to make them move away from the ice-making bottom plate 101;

[0036] The ice making method comprises forming an ice layer on a side of the ice making tray 1 away from the ice making bottom plate 101, wherein the ice layer is used to connect a plurality of ice cubes in a plurality of ice grids, so that the ice cubes in all ice grids can be driven to fall off at the same time under the action of the push rod 3;

[0037] The ice-making method includes an ice-making strategy, the ice-making strategy includes an influencing parameter and an ice layer thickness D, and the ice-making strategy is configured to set the ice layer thickness D according to the influencing parameter, the influencing parameter includes the volume v of the ice cubes in the ice tray, the first inclination angle α formed between the transverse ice-making plate 103 and the ice-making bottom plate 101, and the number n of ice trays. If the volume v of the ice cubes is too large, the weight of the ice cubes is greater, and the ice layer thickness D is larger. If the first inclination angle α is too large, the component force of the weight of the ice cubes along the extension direction of the transverse ice-making plate 103 is large, and the ice layer thickness D is also larger. The number n of ice trays is also positively correlated with the ice layer thickness D.

[0038] Preferably, the ice tray is defined to form a first bottom surface at one side connected to the ice making bottom plate 101, and the area of ​​the ice shedding hole 4 accounts for 1 / 15-1 / 10 of the area of ​​the first bottom surface. If the area of ​​the ice shedding hole 4 accounts for a larger area of ​​the first bottom surface, the ice making quality of the ice cubes in the ice tray will be affected; if the area of ​​the ice shedding hole 4 accounts for a smaller area of ​​the first bottom surface, the required thrust will be greater, which will damage the shape of the contact point between the push rod 3 and the ice cube, and even cause the ice cube to break.

[0039] Preferably, the ice tray 1 further comprises a transverse baffle 7 and a longitudinal baffle fixedly mounted around the ice making bottom plate 101, the transverse baffle 7 is fixedly connected to the plurality of longitudinal ice making plates 102 and the ice making bottom plate 101, the longitudinal baffle is fixedly connected to the plurality of transverse ice making plates 103 and the ice making bottom plate 101, the width of the transverse baffle 7 is the same as the width of the longitudinal baffle, both of which are recorded as d2; the ice making method further comprises a baffle selection strategy, defining the minimum distance between the ice layer and the ice making bottom plate 101 as the ice grid depth d1, the baffle selection strategy is set to calculate the width of the transverse baffle 7 and the width d2 of the longitudinal baffle according to the ice grid depth d1 and the ice layer thickness D, and d2=d1+D. The influencing parameters also include the thickness a1 of the transverse ice making plate 103, the length b1 of the transverse ice making plate 103, the length b2 of the longitudinal ice making plate 102, and the thickness a2 of the longitudinal ice making plate 102. Since the heat is transferred from the ice-making base plate 101, the transverse ice-making plate 103 and the longitudinal ice-making plate 102 as well as the transverse baffle 7 and the longitudinal baffle need to be slowly melted on the side away from the ice-making base plate 101. Therefore, in the second half of the ice-removing stage, a part of the transverse ice-making plate 103, the longitudinal ice-making plate 102, the transverse baffle 7 and the longitudinal baffle will not be melted on the side away from the ice-making base plate 101, especially on the side of the transverse ice-making plate 103 and the longitudinal ice-making plate 102 away from the ice-making base plate 101, there will be a residual connection area, which is basically in a state of not being melted. The area of ​​the residual connection area is equal to the area of ​​the side of the transverse ice-making plate 103 and the longitudinal ice-making plate 102 away from the ice-making base plate 101. The larger the area of ​​the residual connection area, the larger the ice layer thickness D needs to be.

[0040] Preferably, the ice-making method is configured with a push rod 3 setting strategy, and the push rod 3 setting strategy includes setting the number of push rods 3 according to the number of ice trays n, the volume v of ice cubes in the ice trays, and the ratio of the area of ​​the ice-removing holes 4 to the area of ​​the first bottom surface; the push rod 3 setting strategy also includes setting the number of push rods 3 according to the depth d1 of the ice tray, the thickness a1 of the transverse ice-making plate 103, the length b1 of the transverse ice-making plate 103, the length b2 of the longitudinal ice-making plate 102, the thickness a2 of the longitudinal ice-making plate 102, the width d2 of the transverse baffle 7 and the longitudinal baffle, and the push rod 3. The number 3 sets the positions between the push rods 3 so that the maximum difference in the resistance experienced by each push rod 3 does not exceed a first threshold value, and the first threshold value is set to 2%-5% of the average value of the resistance experienced by the push rods 3; in this way, it can be ensured that the ice cubes will not be broken or the ice layer will not be broken during the process of pushing the ice cubes. The influencing parameters also include the first threshold value. If the first threshold value is larger, the required ice cube thickness D will be larger. Otherwise, the ice layer will be broken before the de-icing action is completed, which will reduce the de-icing efficiency.

[0041] Working principle: The ice-making method of the present invention forms an ice layer on the side of the ice-making tray 1 away from the ice-making bottom plate 101, and the ice layer is used to connect the ice cubes in the ice trays, so that the ice cubes in all the ice trays can be driven to fall off at the same time under the action of the push rod 3, thereby improving the quality of ice shedding and also greatly improving the ice-making efficiency; by setting an ice-shedding mechanism, the ice-shedding mechanism drives the push rod 3 to penetrate the ice-shedding hole 4 to apply a force to the ice cubes formed in the ice tray to make them away from the ice-making bottom plate 101, so that ice shedding is convenient and the ice-making efficiency is improved; and by setting the transverse ice-making plate 103 to move away from the connection with the ice-making bottom plate 101 The ice-making bottom plate 101 is tilted downward and extends in the direction of the ice-making bottom plate 101, and a first tilt angle α is formed between the transverse ice-making plate 103 and the ice-making bottom plate 101, and the first tilt angle is an acute angle, and 88°≥α≥83°. Since the vertical downward gravity of the ice cubes themselves will generate a component of gravity along the tilt direction of the transverse ice-making plate 103, a part of the weight of the ice cubes themselves can be used to fall off, and the ice-removing mechanism only uses a small thrust to make the ice cubes completely fall out of the ice grid, avoiding damage to the ice cubes due to excessive thrust, and at the first tilt angle, the ice cubes will not turn white or have gaps, and the ice-making quality is high.

[0042] When in use, when making ice, a cold medium is provided to the copper tube 501 through the water inlet section 502, and the cold medium circulating in the copper tube 501 is used to transfer the cold to the ice-making bottom plate 101, and then to the inside of the ice grid; when the ice cubes are formed and the ice-removing operation is to be performed, the hot medium circulates in the copper tube 501 at this time, which is used to transfer the heat to the ice-making bottom plate 101, and then to the ice cubes inside the ice grid, so that the part of the ice cubes in contact with the transverse ice-making plate 103 and the longitudinal ice-making plate 102 melts until the ice cubes are separated from the ice grid; by setting the pushing direction of the push rod 3 to be the same as the extending direction of the transverse ice-making plate 103, when the ice-removing mechanism is removing ice, the ice can be pushed along the direction in which the ice cubes slide down, avoiding damage to the top of the ice cubes, and further improving the quality of the ice cubes. The ice-making method of the present invention can ensure that the ice layer will not be damaged during the ice-pushing process by setting the ice-making strategy and the push rod 3 setting strategy, so as to avoid causing the ice cubes to not all fall off at once, and the ice-removing efficiency is high.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
