Referring to fig. 1 to 3, the present invention provides an ice making module for making ice cubes or ice particles. The utility model discloses an ice making module 100, including inner bag 110, ice making module 120 and ice screw 130. Wherein, the inner container 110 is provided with an ice storage cavity 112 and an ice outlet 113 corresponding to the ice storage cavity 112. The ice making module 120 is provided in the inner container 110. The ice discharging screw 130 is rotatably disposed in the ice storage cavity 112, and is used for pushing out the ice made by the ice making module 120 from the ice storage cavity 112 to the ice outlet 113 by rotation; the ice screw 130 is spirally disposed, and a pitch of the end of the ice screw 130 close to the ice outlet 113 is greater than a pitch of the end of the ice screw far from the ice outlet 113.

Specifically, the inner container 110 has a water storage cavity 114, a partition 111 is provided above the water storage cavity 114 in the inner container 110, an ice storage cavity 112 is formed on the partition 111, and the ice storage cavity 112 and the water storage cavity 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 drops downward and falls into the water storage cavity 114 through the water flow channel; the ice cubes are stored in the ice storage cavity 112 and pushed out from the ice outlet 113 by the rotation and extrusion of the ice screw 130.

In order to push the ice in the ice storage cavity 112 out of the ice outlet 113, the length direction of the ice screw 130 is consistent with the extending direction of the ice storage cavity 112. The ice discharge screw 130 has a front end near the ice discharge port 113 and a rear end far from the ice discharge port 113. The pitch of the ice screw 130 at the end close to the ice outlet 113 is greater than the pitch of the ice screw at the end far from the ice outlet 113, that is, the pitch of the ice screw 130 at the front end is greater than the pitch of the ice screw at the rear end.

Therefore, the stroke of the ice moving carried by the front end of the ice discharging screw 130 is greater than the stroke of the ice moving carried by the rear end of the ice discharging screw 130 for each rotation of the ice discharging screw 130. Therefore, as the ice discharging screw 130 continuously rotates, the moving speed of the ice discharging screw 130 carrying the ice is gradually increased from back to front, the ice discharging speed is effectively increased, and the ice discharging amount is increased.

As for the manner of driving the ice screw 130 to rotate, theoretically, the ice screw 130 may be driven to rotate by a hand of a user, or may be driven to rotate by the driving motor 141, which is not limited herein. In order to make the ice discharging screw 130 rotate at a high speed and reduce the manual operation of the user, it is preferable to use a motor-driven mode, which will be described in detail later.

The technical scheme of the utility model, through set up rotatable ice screw 130 at the ice storage chamber 112, utilize the rotation of ice screw 130 to release ice making module 120 from ice outlet 113 at the ice storage chamber 112. And the screw pitch of the end of the ice outlet screw 130 close to the ice outlet 113 is designed to be larger than the screw pitch of the end of the ice outlet screw 130 far away from the ice outlet 113, so that the speed of the ice outlet screw 130 carrying ice is gradually increased from back to front in the rotation process of the ice outlet screw 130, the ice outlet speed is effectively increased, and the ice outlet amount is increased.

Referring to fig. 4 to 6, based on any of the above embodiments, in order to realize the rapid rotation of the ice screw 130, the ice making module 100 further includes a driving device 140 disposed on the inner container 110, and the driving device 140 is drivingly connected to the front end or the rear end of the ice screw 130 to drive the ice screw 130 to rotate. Specifically, the driving unit 140 includes a motor 141 and a bushing 142, and a motor shaft of the motor 141 is connected to the ice discharging screw 130 through the bushing 142.

It is considered that the speed of the ice discharging screw 130 moving with the ice is gradually increased from the rear to the front, and thus a large amount of ice is accumulated at the front end of the ice discharging screw 130, so that a large torsion force is required at the front end of the ice discharging screw 130. 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 rapidly pushed out from the ice outlet 113, thereby accelerating the moving speed of the ice.

In view of the fact that the driving unit 140 is coupled to the front end of the ice discharging screw 130, that is, the driving unit 140 is adjacent to the ice outlet 113. Therefore, in order to prevent the driving unit 140 from interfering with the ice outlet 113 to discharge ice, the driving unit 140 is installed at a position higher than the ice outlet 113 of the inner container 110 to avoid the ice outlet 113.

Referring to fig. 2, 5 and 6, for the installation of the driving device 140, the driving device 140 may be directly installed on the inner container 110, or may be indirectly installed on the inner container 110 through other structural components. In one embodiment, the ice making block 100 further includes an ice outlet hopper 150 mounted on the inner container 110, and an inlet end of the ice outlet hopper 150 is butted against the ice outlet 113. The ice pushed out from the ice outlet 113 by the ice discharge screw 130 enters the ice discharge hopper 150 through the inlet end of the ice discharge hopper 150, and is finally discharged from the outlet end of the ice discharge hopper 150. To facilitate installation of the driving means 140, optionally, the driving means 140 is installed to the inner container 110 through the ice discharge hopper 150.

Specifically, the ice discharge hopper 150 includes a hopper base 151 and a hopper cover 152 provided on the hopper base 151. The ice discharging hopper 150 is formed at a side thereof with an inlet end, and the hopper seat 151 is provided with an outlet end provided with a protective cover 154. The top surface of the hopper cover 152 is concavely formed with a mounting groove in which the driving device 140 is mounted. The motor 141 of the driving device 140 has a motor shaft penetrating the hopper cover 152 and connected to the tip of the ice discharge screw 130.

When the ice screw 130 pushes the ice out of the ice outlet 113, the ice enters the ice outlet hopper 150 through the inlet end of the ice outlet hopper 150, and is finally discharged from the outlet end of the ice outlet hopper 150, so that the user can receive the ice.

It is considered that impurities such as dust in the external environment may enter the inner container 110 through the ice outlet hopper 150 to contaminate the inner container 110, thereby affecting the ice outlet quality. To avoid this, an ice outlet door 160 is provided at the inlet end of the ice outlet hopper 150, and the upper end of the ice outlet door 160 is rotatably connected to opposite sidewalls of the inlet end of the ice outlet hopper 150 to rotatably open or close the inlet end.

When the ice discharge screw 130 is rotated, and is pushed out from the ice outlet 113, the pushed ice abuts against the ice discharge door 160, so that the ice discharge door 160 is turned forward and upward to open the inlet end of the ice discharge hopper 150, and the ice is pushed into the ice discharge hopper 150. When the ice screw 130 stops rotating, the ice outlet 113 stops discharging ice, the ice outlet door 160 does not push against the ice, the ice outlet door 160 turns downwards under the action of its own weight to return to the initial state, so as to cover the inlet end of the ice outlet hopper 150, and impurities such as dust in the external environment are difficult to enter the inner container 110.

Referring to fig. 3 and fig. 6, two design manners are illustrated for the ice screw 130 with the pitch of the end near the ice outlet 113 being larger than the pitch of the end far from the ice outlet 113 according to any of the above embodiments. The first method is as follows: the pitch of the ice discharging screw 130 is gradually increased in the ice discharging direction. Namely, the screw pitch of the ice discharging screw is gradually increased from back to front. The second method is as follows: the ice discharging screw 130 is divided into a plurality of stages in the ice discharging direction and is sequentially increased in a stepwise manner. That is, the ice discharging screw 130 is divided into a plurality of sub-screws connected in sequence, the screw pitches of the positions in each sub-screw are the same, and the plurality of sub-screws are arranged in a stepwise increasing manner from the rear to the front.

In one embodiment, in order to facilitate the connection between the ice discharging screw 130 and the driving device 140, a connector 131 for connecting with the driving device 140 extends forward from the front end of the ice discharging screw 130, and the connector 131 may interfere with the ice discharging opening 113 to discharge ice. To solve this problem, the connection head 131 is bent upward to form a bent portion 132 that escapes the ice outlet 113. By such a design, a large expansion space can be formed below the bending portion 132, and the capacity of the ice outlet 113 is increased by the expansion space, so as to ensure a large amount of ice.

Referring to fig. 3, the specific size and structure of the ice screw 130 can be designed according to the size of ice and the ice output requirement. Since the pitch of the ice discharging screw 130 is gradually increased in the ice discharging direction, the ice discharging screw 130 has a minimum pitch at a rear end thereof and a maximum pitch at a front end thereof.

In FIG. 3, D_minExpressed as the minimum pitch, D_maxExpressed as the maximum pitch. If D is_minAnd D_maxIf the difference is too small, the effect of improving the ice discharge rate is not obvious. If D is_minAnd D_maxIf the difference is too large, the ice discharging screw 130 becomes sparse and the strength is reduced, and the ice discharging screw is easy to deform and fail in the ice pushing process. Obviously, D_minAnd D_maxShould be kept within a certain range of ratios.

It is assumed here 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, i.e., D_minAnd D_maxThe ratio of (1)/(N). Obviously, N must be greater than 1. In order to maintain the ice discharging screw 130 with a preferable ice discharging rate, N is optionally not less than 1.5 and not more than 5. The value of N may be, but is not limited to: 1.8, 2.0, 2.3, 2.5, 3.0, 3.5, 4.0, 4.5, 4.8.

When N is less than 1.5, the most D_minAnd D_maxThe difference of (a) is small, the ice discharging screw 130 rotates for one circle, the difference between the moving stroke carried by the front end of the ice discharging screw and the moving stroke carried by the back end of the ice discharging screw is not large, and the ice discharging speed improving effect is not obvious. When N is greater than 5, D_minAnd D_maxThe difference of (a) is large, the ice discharging screw 130 becomes sparse and the strength is reduced, and the deformation and the failure are easily generated in the ice pushing process. Therefore, N is preferably not less than 1.5 and not more than 5.

Further, the minimum pitch of the ice discharging screw 130 is not less than 30mm, and not more than 50 mm. I.e. D_min∈[30mm，50mm]，D_minMay be but is not limited to: 35mm, 38mm, 40mm, 43mm, 45mm, 48mm, 50 mm. The maximum pitch of the ice discharging screw 130 is not less than 50mm and not more than 150 mm. I.e. D_max∈[50mm，150mm]，D_maxCan be selected according to D₁The size of (d) and the selected N value are obtained, which are not described in detail.

Referring to fig. 3, according to any of the above embodiments, the difference between the ice-discharging screw 130 and the conventional ice-discharging screw 130 is that the outer diameter of the ice-discharging screw 130 is kept consistent in the ice-discharging direction. During the rotation of the ice discharging screw 130, the speed at which the ice discharging screw 130 moves with the ice is gradually increased from the rear to the front. Since the outer diameter of the ice discharging screw 130 is maintained to be uniform in the ice discharging direction, the ice discharging screw 130 gradually pushes the ice from the rear to the front, so that the ice is pushed and rapidly discharged from the ice outlet 113.

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 30mm and not more than 80 mm. It should be noted that the outer diameter shall refer to the diameter of an imaginary cylinder coinciding with the crest of the ice-discharging screw 130. As shown by R in the figure, R is represented as half of the outer diameter of the ice discharging screw 130, that is, 15 mm. ltoreq. R.ltoreq.40 mm. The values of R may be, but are not limited to: 18mm, 20mm, 25mm, 30mm, 35mm, 38mm, 40 mm.

Referring to fig. 7, according to any of the above embodiments, the ice making module 120 includes a middle turntable 121, an ice receiving tray 122 disposed on an upper side of the middle turntable 121, an evaporator 123 disposed on an upper side of the ice receiving tray 122, and a water spraying member 124 for spraying water to the evaporator 123. The evaporator 123, the compressor 101, and the condenser 102 are connected in sequence by refrigerant pipes to form a refrigeration cycle.

When the ice making module makes ice, the refrigeration cycle is turned on, the water dripping member 124 drips water onto the evaporator 123 from top to bottom, and the evaporator 123 performs heat exchange with water on the surface thereof, so that the temperature of the water is lowered to form ice and/or ice water. The ice and/or the ice water drops into the ice receiving tray 122 and then moves from the ice receiving tray 122 to the turntable 121. When the ice needs to be discharged, the ice in the middle turntable 121 is transferred to the ice storage cavity 112 and is extruded by the rotation of the ice discharging screw 130, and the ice water in the middle turntable 121 flows into the water storage cavity 114 from the water outlet gap of the middle turntable 121.

There may be various embodiments as to the manner of transferring the ice in the ice receiving tray 122 to the middle turntable 121. Such as but not limited to: an ice outlet is provided in the ice receiving tray 122, and when a certain amount of ice in the ice receiving tray 122 reaches, the ice automatically falls into the turntable 121 through the ice outlet. Or a mechanical arm is added, and the ice in the ice receiving tray 122 is grabbed or pushed into the middle rotating disc 121 by the mechanical arm. Alternatively, the ice receiving tray 122 may be rotatably installed inside the middle turntable 121, and the ice in the ice receiving tray 122 may be tilted downward from one side thereof into the middle turntable 121 by driving the ice receiving tray 122 to be tilted downward. Here, the ice receiving tray 122 employs the latter type of ice transfer.

The ice transfer in the ice tray 122 may be performed in a manner of transferring the ice in the turntable 121 to the ice storage chamber 112. Here, in order to accelerate the ice discharging speed, an ice-stirring blade 125 is optionally disposed at one side of the ice-receiving tray 122, and the ice-stirring blade 125 is rotated by the ice-receiving tray 122 to stir the ice of the middle rotary disk 121 to the ice storage cavity 112.

For example, when the ice receiving tray 122 rotates to the right side thereof, the ice in the ice receiving tray 122 is dumped in the turntable 121 from the left side to the bottom, and at this time, the ice-stirring blade 125 rotates to the right side of the turntable 121 along with the ice receiving tray 122. When the ice receiving tray 122 rotates leftward and returns to the initial position, the ice receiving tray 122 rotates leftward to stir the ice in the middle rotary disk 121 leftward, and the stirred ice reaches a position higher than the side wall 171 of the middle rotary disk 121 and falls into the ice storage cavity 112 from the position.

Referring to fig. 8 and 9, an ice maker 200 is further provided. The ice maker 200 includes a cabinet 210, a drinking water assembly, and an ice making module 100. Wherein, the casing 210 is provided with a water receiving port and an ice receiving port. The drinking water component is communicated with the water receiving port. Detailed structure of the ice making module 100 referring to the above-described embodiment, the ice outlet 113 of the ice making module 100 communicates with the ice receiving port. Since the ice maker 200 adopts all technical solutions of all the embodiments, all the advantages brought by the technical solutions of the embodiments are also achieved, and are not described in detail herein.

In one embodiment, the housing 210 includes a bottom plate 211, a front plate 212, a back plate 213, a left side plate 214, and a right side plate 215. The chassis 211, the front panel 212, the back panel 213, the left side panel 214 and the right side panel 215 enclose a cavity for receiving and installing the drinking water assembly and the ice making module 100.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
