[0036] See also Figures 1 to 3 The present invention provides an ice-making module, which is used to make ice cubes or ice particles. The ice-making module 100 of the present invention includes an inner tank 110, an ice-making module 120 and an ice-discharging screw 130. The inner tank 110 is provided with an ice storage chamber 112 and an ice outlet 113 corresponding to the ice storage chamber 112. The ice-making module 120 is arranged in the inner tank 110. The ice-discharging screw 130 is rotatably arranged in the ice storage chamber 112, and is used to push the ice-making module 120 from the ice storage chamber 112 to the ice outlet 113 through rotation; the ice-discharging screw 130 is arranged in a spiral shape, and the pitch of the ice-discharging screw 130 at one end close to the ice outlet 113 is greater than the pitch of the ice-discharging screw 130 at one end away from the ice outlet 113.

[0037] Specifically, the inner tank 110 has a water storage chamber 114, and the inner tank 110 is provided with a partition 111 above the water storage chamber 114. The ice storage chamber 112 is formed on the partition 111, and the ice storage chamber 112 and the water storage chamber 114 are separated by the partition 111. When the ice making module 100 makes ice, the ice making module 120 makes ice or ice water, wherein the ice water drips downward and falls into the water storage chamber 114 through the water flow channel; ice cubes are stored in the ice storage chamber 112, and are pushed out from the ice outlet 113 by the rotation and squeezing of the ice outlet screw 130.

[0038] In order to facilitate pushing the ice in the ice storage chamber 112 out of the ice outlet 113, the length direction of the ice outlet screw 130 is consistent with the extension direction of the ice storage chamber 112. The ice outlet screw 130 has a front end close to the ice outlet 113 and a rear end away from the ice outlet 113. The pitch of the ice outlet screw 130 at one end close to the ice outlet 113 is greater than the pitch of the end away from the ice outlet 113, that is, the pitch of the front end of the ice outlet screw 130 is greater than the pitch of the rear end.

[0039] Therefore, for each rotation of the ice-discharging screw 130, the distance traveled by the front end of the ice-discharging screw 130 carrying ice is greater than the distance traveled by the rear end of the ice-discharging screw 130. Therefore, as the ice-discharging screw 130 continues to rotate, the speed at which the ice-discharging screw 130 carries ice gradually increases from the back to the front, effectively increasing the ice-discharging speed and thus increasing the amount of ice-discharging.

[0040] As for the method of driving the ice-out screw 130 to rotate, theoretically, the ice-out screw 130 can be driven to rotate by a user's hand crank or by a driving motor 141, and there is no limitation here. In order to make the ice-out screw 130 rotate quickly and reduce the manual operation of the user, it is preferably driven by an electric drive method, which will be described in detail later.

[0041] The technical solution of the present invention is to arrange a rotatable ice-discharging screw 130 in the ice storage chamber 112, and to use the rotation of the ice-discharging screw 130 to push the ice dropped by the ice-making module 120 into the ice storage chamber 112 from the ice outlet 113. The pitch of the ice-discharging screw 130 at one end close to the ice outlet 113 is designed to be greater than the pitch of the ice-discharging screw 130 at one end away from the ice outlet 113, so that during the rotation of the ice-discharging screw 130, the speed of the ice-discharging screw 130 carrying ice is gradually increased from the back to the front, thereby effectively increasing the ice-discharging speed and thus increasing the ice-discharging amount.

[0042] See also Figures 4 to 6 Based on any of the above embodiments, in order to realize the rapid rotation of the ice-discharging screw 130, the ice-making module 100 further includes a driving device 140 disposed on the inner tank 110, and the driving device 140 is drivingly connected to the front end or the rear end of the ice-discharging screw 130 to drive the ice-discharging screw 130 to rotate. Specifically, the driving device 140 includes a motor 141 and a shaft sleeve 142, and the motor shaft of the motor 141 is connected to the ice-discharging screw 130 through the shaft sleeve 142.

[0043] It is considered that since the speed of the ice-discharging screw 130 carrying ice gradually increases from the back to the front, more ice will be accumulated at the front end of the ice-discharging screw 130, so the front end of the ice-discharging screw 130 needs a larger torque. Therefore, the driving device 140 is connected to the front end of the ice-discharging screw 130 to provide a strong driving force to the front end of the ice-discharging screw 130, so that the ice accumulated at the front end of the ice-discharging screw 130 is quickly pushed out from the ice outlet 113, thereby accelerating the moving speed of the ice.

[0044] Since the driving device 140 is connected to the front end of the ice outlet screw 130, that is, the driving device 140 is close to the ice outlet 113, in order to prevent the driving device 140 from interfering with the ice outlet 113, the driving device 140 is installed at a position higher than the ice outlet 113 of the inner container 110 to avoid the ice outlet 113.

[0045] See also Figure 2 , Figure 5 and Figure 6 Regarding the installation of the driving device 140, the driving device 140 can be directly installed on the inner tank 110, or can be indirectly installed on the inner tank 110 through other structural components. In one embodiment, the ice making device 100 also includes an ice hopper 150 installed on the inner tank 110, and the inlet end of the ice hopper 150 is connected to the ice outlet 113. The ice pushed out from the ice outlet 113 by the ice screw 130 enters the ice hopper 150 through the inlet end of the ice hopper 150, and is finally discharged from the outlet end of the ice hopper 150. To facilitate the installation of the driving device 140, optionally, the driving device 140 is installed on the inner tank 110 through the ice hopper 150.

[0046] Specifically, the ice hopper 150 includes a hopper seat 151 and a hopper cover 152 disposed on the hopper seat 151. An inlet end is formed on the side of the ice hopper 150, and the hopper seat 151 is provided with an outlet end, and the outlet end is provided with a protective cover 154. A mounting groove is formed on the top surface of the hopper cover 152, and the driving device 140 is installed in the mounting groove. The motor shaft of the motor 141 of the driving device 140 passes through the hopper cover 152 and is connected to the front end of the ice screw 130.

[0047] When the ice-discharging screw 130 pushes the ice out of the ice-discharging port 113 , the ice enters the ice-discharging hopper 150 through the inlet end of the ice-discharging hopper 150 , and is finally discharged from the outlet end of the ice-discharging hopper 150 for the user to receive the ice.

[0048] It is also considered that dust and other impurities in the external environment may enter the inner container 110 through the ice hopper 150, contaminating the inner container 110 and affecting the quality of ice output. To avoid this, an ice door 160 is provided at the inlet end of the ice hopper 150, and the upper end of the ice door 160 is rotatably connected to the opposite side walls of the inlet end of the ice hopper 150 to rotate to open or close the inlet end.

[0049] When the ice-discharging screw 130 rotates, the ice is pushed out from the ice-discharging port 113, and the pushed-out ice pushes against the ice-discharging door 160, so that the ice-discharging door 160 flips forward and upward to open the inlet end of the ice-discharging hopper 150, and the ice is pushed into the ice-discharging hopper 150. When the ice-discharging screw 130 stops rotating, the ice-discharging port 113 stops discharging ice, and the ice-discharging door 160 has no ice to push against. The ice-discharging door 160 flips downward under its own gravity to return to its initial state, thereby covering the inlet end of the ice-discharging hopper 150, and dust and other debris in the external environment are difficult to enter the inner tank 110.

[0050] See also Figure 3 and Figure 6 Based on any of the above embodiments, for the design methods in which the pitch of the ice-discharging screw 130 at one end close to the ice outlet 113 is greater than the pitch at the end away from the ice outlet 113, two examples are given here. Method 1 is: the pitch of the ice-discharging screw 130 is gradually increased in the ice-discharging direction. That is, the pitch of the ice-discharging screw gradually increases from back to front. Method 2 is: the ice-discharging screw 130 is divided into multiple sections in the ice-discharging direction and is increased in a step-like manner. That is, the ice-discharging screw 130 is divided into multiple sections of sub-screws connected in sequence, and the pitches of each position in each section of the sub-screw are the same, and the pitches of the multiple sections of the sub-screws are increased in a step-like manner from back to front.

[0051] In one embodiment, in order to facilitate the connection between the ice-discharging screw 130 and the driving device 140, the front end of the ice-discharging screw 130 extends forward to have a connector 131 for connecting with the driving device 140, and the connector 131 may also interfere with the ice-discharging of the ice-discharging port 113. In order to solve this problem, the connector 131 is bent upward to form a bent portion 132 that avoids the ice-discharging port 113. With this design, a larger expansion space can be formed below the bent portion 132, and the expanded space increases the capacity at the ice-discharging port 113, thereby ensuring a large amount of ice-discharging.

[0052] See also Figure 3 The specific size structure of the ice-discharging screw 130 can be designed according to the size of ice and the amount of ice-discharging required. Since the pitch of the ice-discharging screw 130 gradually increases in the ice-discharging direction, the ice-discharging screw 130 has a minimum pitch at its rear end and a maximum pitch at its front end.

[0053] exist Figure 3 Middle, D minExpressed as the minimum pitch, D max It is expressed as the maximum pitch. If D min With D max If the difference is too small, the improvement effect on ice output rate will not be obvious. min With D max If the difference is too large, the ice screw 130 will become sparse and reduce its strength, and it will be easily deformed and fail during the ice pushing process. min With D max It should be kept within a certain proportion.

[0054] It is assumed that the ratio of the minimum pitch of the ice-discharging screw 130 to the maximum pitch of the ice-discharging screw 130 is 1:N, that is, D min With D max The ratio of is 1:N. Obviously, N must be greater than 1. In order to maintain a better ice-out rate of the ice-out screw 130, optionally, N is not less than 1.5 and not greater than 5. The value of N can be, but is not limited to, 1.8, 2.0, 2.3, 2.5, 3.0, 3.5, 4.0, 4.5, 4.8.

[0055] When N is less than 1.5, the maximum min With D max The difference is small, and the ice-discharging screw 130 rotates one circle, and the distance of the front end carrying and moving ice is not much different from the distance of the rear end carrying and moving ice, and the ice-discharging rate improvement effect is not obvious. When N is greater than 5, D min With D max The difference is large, the ice screw 130 becomes sparse and the strength is reduced, and it is easy to deform and fail during the ice pushing process. Therefore, it is preferred that N is not less than 1.5 and not greater than 5.

[0056] Furthermore, the minimum pitch of the ice-discharging screw 130 is not less than 30 mm and not more than 50 mm. min ∈[30mm, 50mm], D min It can be but not limited to: 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50mm. The maximum pitch of the ice-discharging screw 130 is not less than 50mm and not more than 150mm. max ∈[50mm, 150mm], D max The selection of can be obtained according to the size of D1 and the selected N value, and the details are not described one by one.

[0057] Please continue reading Figure 3Based on any of the above embodiments, the difference from the conventional method in which the outer diameter of the ice-discharging screw 130 gradually increases in the ice-discharging direction is that the outer diameter of the ice-discharging screw 130 remains the same in the ice-discharging direction. During the rotation of the ice-discharging screw 130, the speed at which the ice-discharging screw 130 carries ice and moves gradually increases from the back to the front. Since the outer diameter of the ice-discharging screw 130 remains the same in the ice-discharging direction, the ice-discharging screw 130 gradually squeezes the ice from the back to the front, so that the ice is pushed and quickly discharged from the ice outlet 113.

[0058] As for the size of the outer diameter of the ice-discharging screw 130, optionally, the outer diameter of the ice-discharging screw 130 is not less than 30 mm and not more than 80 mm. It should be noted that the outer diameter should refer to the diameter of an imaginary cylinder that coincides with the thread top of the ice-discharging screw 130. As shown in R in the figure, R represents half of the outer diameter of the ice-discharging screw 130, that is, 15mm≤R≤40mm. The value of R can be, but is not limited to: 18mm, 20mm, 25mm, 30mm, 35mm, 38mm, 40mm.

[0059] See also Figure 7 Based on any of the above embodiments, the ice making module 120 includes a central rotating disk 121, an ice receiving tray 122 disposed on the upper side of the central rotating disk 121, an evaporator 123 disposed on the upper side of the ice receiving tray 122, and a water spraying member 124 for spraying water to the evaporator 123. The evaporator 123 is connected to the compressor 101 and the condenser 102 in sequence through a refrigerant pipe to form a refrigeration cycle system.

[0060] When the ice-making module makes ice, the refrigeration cycle system is turned on, and the water-sprinkling member 124 sprinkles water from top to bottom onto the evaporator 123. The evaporator 123 exchanges heat with the water on its surface, so that the temperature of this part of water is reduced to form ice and / or ice water. The ice and / or ice water first falls into the ice receiving tray 122, and then moves from the ice receiving tray 122 to the transfer tray 121. When ice is needed, the ice in the transfer tray 121 is transferred to the ice storage chamber 112, and is squeezed out by the ice-discharging screw 130, and the ice water in the transfer tray 121 flows from the water outlet gap of the transfer tray 121 to the water storage chamber 114.

[0061] There are many ways to transfer the ice in the ice receiving tray 122 to the transfer tray 121. For example, but not limited to: an ice outlet hole is set in the ice receiving tray 122, and when the ice in the ice receiving tray 122 reaches a certain amount, it falls into the transfer tray 121 from the outlet hole. Alternatively, a manipulator is added to grab or transfer the ice in the ice receiving tray 122 to the transfer tray 121. Alternatively, the ice receiving tray 122 is rotatably installed on the inner side of the transfer tray 121, and the ice receiving tray 122 is driven to flip downward, so that the ice in the ice receiving tray 122 is poured downward from one side into the transfer tray 121. Specifically, the ice receiving tray 122 adopts the latter method of transferring ice.

[0062] The method of transferring the ice in the central transfer tray 121 to the ice storage chamber 112 can also be implemented by referring to the method of transferring ice in the ice receiving tray 122. In order to speed up the ice output, an ice scraper 125 is optionally provided on one side of the ice receiving tray 122. The ice scraper 125 is driven by the ice receiving tray 122 to rotate and scrape the ice in the central transfer tray 121 to the ice storage chamber 112.

[0063] For example, when the ice receiving tray 122 rotates to the right, the ice in the ice receiving tray 122 pours down from the left into the middle turntable 121. At this time, the ice shovel 125 rotates to the right side of the middle turntable 121 along with the ice receiving tray 122. When the ice receiving tray 122 rotates to the left to return to the initial position, the ice shovel 125 rotates to the left with the ice receiving tray 122, thereby moving the ice in the middle turntable 121 to the left. When the moved ice reaches a position higher than the side wall 171 of the middle turntable 121, it falls into the ice storage chamber 112 from this position.

[0064] See also Figure 8 and Fig. 9 The present invention also provides an ice maker 200. The ice maker 200 includes a housing 210, a drinking water component and an ice making module 100. The housing 210 is provided with a water inlet and an ice receiving port. The drinking water component is connected to the water inlet. The specific structure of the ice making module 100 refers to the above embodiment, and the ice outlet 113 of the ice making module 100 is connected to the ice receiving port. Since the ice maker 200 adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0065] In one embodiment, the housing 210 includes a bottom plate 211, a panel 212, a back plate 213, a left side plate 214, and a right side plate 215. The bottom plate 211, the panel 212, the back plate 213, the left side plate 214, and the right side plate 215 enclose a cavity, and the cavity can accommodate and install the drinking water component and the ice making module 100.
