[0002] The ice-making module usually rotates an ice-discharging screw to squeeze and push the ice out of the ice outlet. The ice-making module usually has an ice-discharging door at the ice outlet, which is used to open or close the ice outlet to prevent dust, bacteria and other debris from the external environment from entering the interior of the ice-making module through the ice outlet. However, conventional ice-making modules usually require additional solenoid valves or motors to drive the ice door to open and close, which increases the cost of the ice-making module and is not conducive to cost saving.

The ice-discharging screw is rotatably arranged in the ice storage cavity, and is used to push the ice in the ice storage cavity out of the ice-discharging port by rotation. The upper end of the ice-discharging door is rotatably arranged in the ice-discharging port, so that the ice pushed out by the ice-discharging screw drives the ice-discharging door to flip upward, thereby opening the ice-discharging port.

[0009] Optionally, the locking member includes a side wall having the rack and a top wall connected to the upper end of the side wall; the driving device also includes an elastic member, the upper end of the elastic member is connected to the top wall, and the lower end of the elastic member is fixed to the upper plate surface of the mounting plate.

[0010] Optionally, the locking member further comprises a limiting column which is arranged on the top wall and extends in the up-down direction, the elastic member is sleeved on the limiting column, and the upper end of the elastic member is fixed to the limiting column so as to be connected to the top wall via the limiting column.

[0011] Optionally, a stop protrusion is provided on a plate surface of the ice discharging door facing away from the ice discharging screw, and after the ice discharging door is flipped upward to open the ice discharging port, the stop protrusion abuts against a structure of the ice-making module located above the ice discharging door.

[0012] Optionally, the ice-making module further includes an ice-making module group, which is disposed in the inner tank, and ice generated by the ice-making module group falls into the ice storage cavity.

[0013] Optionally, the ice-making module includes a central turntable, an ice receiving tray disposed on the upper side of the central turntable, an evaporator disposed on the upper side of the ice receiving tray, and a water sprinkling member for supplying water to the evaporator.

[0014] Optionally, the ice receiving tray is rotatably mounted on the central rotating tray, and an ice scraper is provided on one side of the ice receiving tray. The ice scraper is driven to rotate by the ice receiving tray to scrape the ice on the central rotating tray to the ice storage cavity.

It can be seen that the ice-making module of the present invention does not need to add an additional solenoid valve or motor to drive the opening and closing of the ice-discharging door, which effectively reduces the cost.

[0032] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

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.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0036] See also Figures 1 to 3The present invention provides an ice-making module 100, and the ice-making module 100 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-discharging screw 130 and an ice-discharging door 160. The inner tank 110 is provided with an ice storage chamber 112 and an ice-discharging port 113 corresponding to the ice storage chamber 112. The ice-discharging screw 130 is rotatably disposed in the ice storage chamber 112, and is used to push the ice in the ice storage chamber 112 out of the ice-discharging port 113 by rotation. The upper end of the ice-discharging door 160 is rotatably disposed at the ice-discharging port 113, so that the ice pushed out by the ice-discharging screw 130 drives the ice-discharging door 160 to flip upward, thereby opening the ice-discharging port 113.

[0037] The ice discharging door 160 located at the ice discharging port 113 is in a state of closing the ice discharging port 113 in the initial position. When the ice squeezed and pushed out to the ice discharging port 113 hits the ice discharging door 160, the ice discharging door 160 is pushed by the ice and flipped in a direction away from the ice discharging screw 130 to open the ice discharging port 113. At this time, the ice discharging door 160 is in an open position, and ice can be discharged from the ice discharging port 113. When the ice discharging screw 130 stops pushing ice, no ice is squeezed out of the ice discharging port 113, so that the ice discharging door 160 loses its thrust and falls back to the initial position under the action of its gravity.

[0038] 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.

[0039] The technical solution of the present invention is to arrange a rotatable ice-discharging screw 130 in the ice storage chamber 112, and to rotate the ice-discharging screw 130 to push the ice dropped from the ice storage chamber 112 by the ice-making module 120 out of the ice outlet 113. The ice-discharging door 160 is arranged at the ice outlet 113, and the upper end of the ice-discharging door 160 is rotatably arranged at the ice outlet 113, so that the ice-discharging door 160 can be turned over to open the ice outlet 113 by the ice pushed out by the ice-discharging screw 130, and after the ice-discharging screw 130 stops pushing ice, the ice-discharging door 160 falls back to the initial position under the action of its gravity. It can be seen that the ice-making module 100 of the present invention does not need to add an additional solenoid valve or motor 141 to drive the ice-discharging door 160 to open and close, which effectively reduces the cost.

[0040] See also Figures 3 to 5Based on the above embodiment, regarding the installation of the ice discharging door 160, the ice discharging door 160 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 module 100 further includes an ice discharging hopper 150 disposed at the ice discharging port 113, and the inlet end of the ice discharging hopper 150 is connected to the ice discharging port 113. To facilitate the installation of the ice discharging door 160, the upper end of the ice discharging door 160 is rotatably installed at the inlet end of the ice discharging hopper 150.

[0041] Specifically, the ice discharging 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 discharging 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 rotating shaft 161 is provided at the upper end of the ice discharging door 160, and the two ends of the rotating shaft 161 are respectively rotatably connected to the two side walls 171 of the inlet end of the ice discharging hopper 150. When the ice discharging screw 130 pushes the ice out of the ice discharging port 113, the ice discharging door 160 is pushed open, and 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.

[0042] See also Figures 5 to 7 In one embodiment, when the ice discharging door 160 is in the initial position (i.e., the air outlet is closed), the ice discharging door 160 is not restricted and is easy to shake and unstable. In order to solve this problem, the ice discharging hopper 150 has a mounting plate 153 located above the ice discharging door 160, and the mounting plate 153 is provided with a locking member 170 movable in the up-down direction. The locking member 170 has a avoiding state in which the ice discharging door 160 is moved upward to avoid opening the ice discharging port 113, and a locking state in which the ice discharging door 160 is moved downward to close the ice discharging port 113.

[0043] exist Figure 6 and Figure 7 In the figure, f1 indicates the rotation direction of the locking member. Figure 6 As shown, when the locking member 170 is in the locked state, the locking member 170 is located on the side of the ice discharging door 160 that is opposite to the ice discharging screw 130. When the ice discharging screw 130 pushes ice toward the ice discharging port 113, the locking member 170 moves upward to the avoidance state, and the pushed ice can push the ice discharging door 160 to flip open the ice discharging port 113, and the ice can be discharged from the ice discharging port 113. Figure 7 As shown, when the ice discharging screw 130 stops pushing ice toward the ice discharging port 113, the ice discharging door 160 returns to its initial position. At this time, the locking member 170 moves downward and locks the ice discharging door 160, positioning the ice discharging door 160 at the initial position so that the ice discharging door 160 is not easy to move.

[0044] As for the method of driving the locking member 170 to move, there are many design methods. Here are two examples:

[0045] One of the driving modes of the locking member 170: a downwardly opening accommodating cavity is provided on the mounting plate 153, and an elastic member 180 that can be extended and retracted in the up-down direction is provided in the accommodating cavity, and the lower end of the elastic member 180 is connected to the locking member 170. When the ice discharging door 160 is pushed open by ice, the ice discharging door 160 pushes the locking member 170 and moves upward to avoid the ice discharging door 160, and at this time, the elastic member 180 is squeezed and accumulates elastic potential energy. When the ice discharging door 160 stops discharging ice, the ice discharging door 160 falls back to the initial position, and at this time, the elastic member 180 releases its elasticity and pushes the locking member 170 to move downward, and then the locking member 170 limits the movement of the ice discharging door 160.

[0046] Second driving method of the locking member 170: The ice-making module 100 further includes a driving device 140 for driving the ice-discharging screw 130 to rotate. The driving device 140 is also connected to the locking member 170. The driving device 140 can drive the locking member 170 and the ice-discharging screw 130 to move simultaneously. In this way, the locking member 170 and the ice-discharging screw 130 can be driven to move simultaneously by one driving device 140, without the need to add another driving device. In order to ensure the stability of the movement of the locking member 170, the second driving method is adopted here to use the driving device 140 to assist the movement of the locking member 170.

[0047] See also Figure 4 , Figure 6 and Figure 7 In one embodiment, the driving device 140 includes a motor 141 and a gear 142. The motor shaft of the motor 141 passes through the gear 142 and is connected to the ice-discharging screw 130. The upper part of the side surface of the locking member 170 is provided with a rack 173 extending in the up and down directions and meshing with the gear 142. When the motor 141 drives the ice-discharging screw 130 to push ice, the gear 142 drives the locking member 170 to move upward to the avoidance state through the rack 173.

[0048] exist Figure 6 and Figure 7 In the figure, f2 indicates the direction of rotation of the gear. Figure 6 As shown, when the ice-making module 100 is discharging ice, the motor 141 drives the ice-discharging screw 130 to rotate forwardly through the gear 142, and the gear 142 meshes with the rack 173 of the locking member 170 and drives the locking member 170 to move upward until the locking member 170 moves to the lowest tooth groove of its rack 173 and meshes with the gear 142, and the locking member 170 reaches the avoidance state, and the ice-discharging door 160 is pushed open by the ice squeezed out by the ice-discharging screw 130; at this time, the motor 141 can continuously drive the gear 142 and the ice-discharging screw 130 to rotate and push the ice, and will not interfere with the locking member 170.

[0049] like Figure 7As shown, when the ice-making module 100 stops discharging ice, the motor 141 drives the ice-discharging screw 130 to rotate in the opposite direction through the gear 142, and the gear 142 meshes with the rack 173 of the locking member 170 and drives the locking member 170 to move downward until the locking member 170 moves to the topmost tooth groove of its rack 173 and meshes with the gear 142, and the locking member 170 reaches the locked state, and the ice-discharging door 160 returns to its initial position and is locked by the locking member 170. At this time, the motor 141 can be turned off.

[0050] See also Figure 6 and Figure 7 Furthermore, in order to improve the installation stability of the locking member 170, the locking member 170 includes a side wall 171 having a rack 173 and a top wall 172 connected to the upper end of the side wall 171; the ice-making module 100 also includes an elastic member 180, the upper end of the elastic member 180 is connected to the top wall 172, and the lower end of the elastic member 180 is fixed to the upper plate surface of the mounting plate 153.

[0051] When the locking member 170 is in the locked state, the top wall 172 of the locking member 170 presses the elastic member 180 against the mounting plate 153, and the elastic member 180 accumulates elastic potential energy; once the ice-making module 100 starts to dispense ice, the motor 141 drives the gear 142 to rotate forward, and the locking member 170 is driven by the gear 142 to move upward. At this time, the elastic member 180 releases the elastic potential energy and pushes the locking member 170 to assist the locking member 170 to move upward. When the locking member 170 moves to the lowest tooth groove of the rack 173 and meshes with the gear 142, the elastic member 180 returns to its original state.

[0052] As the motor 141 continues to drive the gear 142 and the ice-discharging screw 130 to rotate and push the ice, the convex teeth on the circumference of the gear 142 mesh with the lowest tooth groove of the rack 173 in turn, causing the locking member 170 to have a slight upward and downward displacement. At this time, the presence of the elastic member 180 can effectively buffer the slight displacement of the locking member 170 and reduce the resistance of the locking bar to the rotation of the gear 142 (ice-discharging screw 130).

[0053] As for the type of the elastic member 180, it can be a spring, or a spring, or a coil spring, or a sponge. In the present embodiment, the elastic member 180 is a spring. Considering that the spring may deviate from its axial position during the process of upward and downward extension. Therefore, in order to limit the extension direction of the elastic member 180, the locking member 170 also includes a limiting column 174 provided on the top wall 172 and extending in the upward and downward directions. The elastic member 180 is sleeved on the limiting column 174, and the upper end of the elastic member 180 is fixed to the limiting column 174 so as to be connected to the top wall 172 through the limiting column 174. During the upward and downward extension of the elastic member 180, the elastic member 180 always remains sleeved on the limiting column 174 and does not easily deviate from its axial position.

[0054] See also Figure 8 Based on any of the above embodiments, in order to facilitate the ice discharging door 160 to return to its initial position under the action of its gravity, a stop protrusion 162 is convexly provided on the plate surface of the ice discharging door 160 that is away from the ice discharging screw 130. After the ice discharging door 160 is flipped upward to open the ice discharging port 113, the stop protrusion 162 abuts against the structure of the ice-making module 100 located above the ice discharging door 160.

[0055] Specifically, when the ice discharging door 160 is opened until the stop protrusion 162 on the back side thereof abuts against the structure above the ice discharging door 160 (for example, the mounting plate 153), the flipping angle of the ice discharging door 160 is less than 90°. At this time, the ice discharging door 160 is in a downward tilted state, and the center of gravity of the ice discharging door 160 is downward, so that after the ice discharging stops, the ice discharging door 160 quickly falls back to the initial position under the action of its gravity.

[0056] See also Fig. 9 Based on any of the above embodiments, the inner tank 110 of the ice making module 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. The ice making module also includes an ice making module 120 disposed above the ice storage chamber 112. The ice made by the ice making module 120 is stored in the ice storage chamber 112, and then the ice is pushed out by the ice discharging screw 130 by rotation and extrusion.

[0057] In one embodiment, the ice making module 120 includes a central rotating plate 121, an ice receiving tray 122 disposed on the upper side of the central rotating plate 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] See also Fig.10 and Fig.11 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.

[0063] 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.

[0064] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
