[0002] Existing snowflake machines are usually open, and the ice making roller and the scraper are exposed during the process of making snowflake ice, which has a great safety hazard. For example, a Chinese utility model patent with the authorization announcement number CN222143447U provides an ice making mechanism and a snow ice machine, and the ice making components of the ice making roller and the scraper are exposed during ice making, and the hand can touch the scraper and the rotating ice making roller, which has poor safety performance and cannot provide reliable safety protection for users.

[0003] In order to solve the safety problem, a Chinese patent application with the application publication number CN119958170A provides a household snow ice machine top cabin door with a safety protection mechanism, which solves the safety problem by setting a protection mechanism, an opening and closing mechanism and two protection cabin doors, but the structure is complex, the structure around the evaporator is closed, there is a dead angle for cleaning, and there is a food hygiene problem in long-term use. SUMMARY

[0004] In view of the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a snowflake ice making assembly and a snowflake machine which can provide safety protection and are convenient to clean.

[0005] The technical solution adopted by the embodiments of the present application is that the snowflake ice making assembly is used in the snowflake machine, and the snowflake ice making assembly comprises:

[0006] A shell, the top and the front side of which are open;

[0007] An evaporator, the outer peripheral surface of which is a cylindrical surface and forms an ice making surface, and the evaporator is rotatably arranged in the shell;

[0008] A sensor arranged on the shell and connected with a control module of the snowflake machine;

[0009] A top cover assembly rotatably arranged on the top of the shell and used for opening or closing the top opening of the shell;

[0011] A trigger mechanism is arranged at a front position on the inner side of the top cover assembly or at a top position on the inner side of the front door assembly. When both the front door assembly and the top cover assembly are closed, the front door assembly or the top cover assembly pushes against the trigger mechanism, which triggers the sensor. The sensor sends a first signal to the control module, which controls the rotation of the evaporator. When the front door assembly or the top cover assembly is opened, the trigger mechanism is released from triggering the sensor, and the sensor sends a second signal to the control module, which controls the stop of the evaporator.

[0058] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted.

[0059] The embodiments of the present application provide a snowflake ice making assembly for a snowflake machine. As shown in Figures 1 to 5 , the snowflake ice making assembly comprises a shell 1, an evaporator 2, a sensor 3, a top cover assembly 4, a front door assembly 5, and a trigger mechanism 6.

[0060] As shown in Figure 6 , the top and front side of the shell 1 are open, i.e. the shell 1 has a top opening and a front opening. In the present application, the front side refers to the side facing the user during use, while the back side refers to the side away from the user during use.

[0061] As shown in Figures 1 to 5 , the outer peripheral surface of the evaporator 2 is a cylindrical surface and forms an ice making surface, i.e. the evaporator 2 is formed in a drum shape and rotates in the shell 1, and the axis of the evaporator 2 is arranged horizontally.

[0062] The sensor 3 is arranged near the top of the shell 1, as shown in Figure 10 , the sensor 3 is connected to the control module 50 of the snowflake machine, and is at least used to send signals to the control module 50.

[0063] As shown in Figure 3 and Figure 4 , the top cover assembly 4 is rotatably arranged on the top of the shell 1, and is used to open or close the top opening of the shell 1. For example, the rear ends of the top cover 41 have hinge holes 42, and the upper ends of the rear sides of the first side plate 11 and the second side plate 12 have pin shafts 119, which are arranged one by one in the two hinge holes 42, respectively, so that the top cover 41 is rotatably connected with the first side plate 11 and the second side plate 12.

[0064] AsFigure 2 As shown, the front door assembly 5 is rotatably arranged at the front side of the shell 1, and is used to open or close the front side opening of the shell 1, so as to form a closed space in the shell 1 in cooperation with the top cover assembly 4.

[0065] The trigger mechanism 6 is arranged at the front side of the top cover assembly 4 or at the top side of the front door assembly 5. When the front door assembly 5 and the top cover assembly 4 are both closed, the evaporator 2 and the scraper 9 (to be introduced below) can be enclosed in the shell 1, so as to avoid being exposed and causing accidental injury to the user. Moreover, when the trigger mechanism 6 is arranged on the top cover assembly 4, the front door assembly 5 pushes against the trigger mechanism 6, so that the trigger mechanism 6 triggers the sensor 3. When the trigger mechanism 6 is arranged on the front door assembly 5, the top cover assembly 4 pushes against the trigger mechanism 6, so that the trigger mechanism 6 triggers the sensor 3. When the sensor 3 is triggered, the sensor 3 sends a first signal to the control module 50, and the control module 50 receives the first signal and controls the rotation of the evaporator 2. When the front door assembly 5 is opened, the trigger mechanism 6 releases the triggering of the sensor 3, and the sensor 3 sends a second signal to the control module 50, and the control module 50 receives the second signal and controls the rotation of the evaporator 2.

[0066] The snowflake ice making assembly of the present application is arranged with the front door assembly 5 and the top cover assembly 4, and the trigger mechanism 6 triggers the sensor 3 only when the front door assembly 5 and the top cover assembly 4 are both closed. Therefore, the evaporator 2 can be started only when the front door assembly 5 and the top cover assembly 4 are both closed, so as to not only enclose the scraper 9 and the rotating evaporator 2 in a specific space and reduce the risk of touching, but also stop the snowflake ice making immediately when any one of the front door assembly 5 and the top cover assembly 4 is opened, so as to improve the safety performance. Moreover, after the snowflake ice making is completed, the front door assembly 5 and the top cover assembly 4 are opened, and the evaporator 2 and the surrounding position are exposed, so as to facilitate the direct use of clean water to spray and a cloth to wipe the evaporator 2 and the surrounding position, improve the convenience of cleaning, avoid the health dead angle, and ensure the food safety. The present application has a clever design, and a variety of effects can be achieved by a relatively simple structure.

[0067] The principle of triggering the trigger mechanism 6 arranged on the top cover assembly 4 or the front door assembly 5 is basically the same, and the present application will be described by taking the trigger mechanism 6 arranged on the top cover assembly 4 as an example.

[0068] In some embodiments, as Figure 6As shown, the shell 1 comprises opposite first side plate 11 and second side plate 12, and bottom plate 13 connecting the bottom of both first side plate 11 and second side plate 12, i.e. the front side between the bottom of both first side plate 11 and second side plate 12 is hollow and not shielded. The first side plate 11 is provided with concave cavity 111 inside from its top surface, and the concave cavity 111 is formed with front opening towards the front side of the first side plate 11. When the top cover assembly 4 is closed, the trigger component of the trigger mechanism 6 provided on the top cover assembly 4 extends into the concave cavity 111 and partially extends out of the front opening of the front side of the first side plate 11, so that when the front door assembly 5 is closed, the inner side of the top of the front door assembly 5 pushes against the trigger component to move the trigger component into the concave cavity 111 to trigger the sensor 3. The present application sets the concave cavity 111 on the front side of the first side plate 11 of the shell 1, so that when the top cover assembly 4 is closed, the first side plate 11 avoids the trigger component of the trigger mechanism 6, and the trigger component protrudes towards the front side, so that when the front door assembly 5 is closed, the inner side of the front door assembly 5 pushes against the trigger component to trigger the sensor 3, which is a reasonable and ingenious structure layout design that can only trigger the sensor 3 when both the front door assembly 5 and the top cover assembly 4 are closed.

[0069] In some embodiments, as Figures 7 to 9 As shown, the trigger mechanism 6 further comprises slider cover 63 and reset component 64, the slider cover 63 is provided on the inner side of the top cover 41 and forms a chamber with the top cover 41, and the slider cover 63 is provided with strip-shaped slot 631. The trigger component comprises slider 61, and the slider 61 and the reset component 64 are both provided in the chamber, and the lower part of the slider 61 extends out of the chamber through the strip-shaped slot 631. The two ends of the reset component 64 act on the slider cover 63 and the slider 61 respectively, and are used to apply an acting force to the slider 61 to move it in the first direction, so as to reset the slider 61. When the top cover assembly 4 is closed, the lower part of the slider 61 extends into the concave cavity 111, and when the front door assembly 5 is closed, the inner side of the top of the front door assembly 5 pushes against the outer side of the lower part of the slider 61 to move the slider 61 in the second direction opposite to the first direction, so as to trigger the sensor 3. When the slider 61 moves in the second direction, the reset component 64 is compressed and accumulates elastic potential energy. When the front door assembly 5 is opened and the pushing of the slider 61 is released, the reset component 64 releases the elastic potential energy and pushes the slider 61 to move in the first direction, so as to reset the slider 61. The first direction refers to the direction from the rear side to the front side, and the second direction refers to the direction from the front side to the rear side. The trigger mechanism 6 is reasonably designed, and the slider 61 is conveniently pushed to move when both the top cover assembly 4 and the front door assembly 5 are closed, and the slider 61 is in contact with the sensor 3 by moving to trigger the sensor 3.

[0070] Further, continuing to combine Figures 7 to 10The slider 61 comprises a plate-shaped bottom 611 and a tongue 612 arranged on the first side of the bottom 611. The first side of the bottom 611 is attached to the inner side of the slider cover 63 and can slide along the inner side of the slider cover 63. A positioning rod 62 is arranged on the first side of the bottom 611 adjacent to the first side thereof. The return component 64 can be a spring. The spring is sleeved on the positioning rod 62. One end of the spring is abutted against the first side of the bottom 611, and the other end of the spring is abutted against the portion of the slider cover 63 facing the first side of the bottom 611. The tongue 612 extends out of the cavity through the strip-shaped slot 631. The length of the strip-shaped slot 631 is greater than the length of the sliding direction of the tongue 612, so that the tongue 612 slides (reciprocally slides in the direction of the arrow shown in the figure) in the strip-shaped slot 631. The slider 61 in this structure can be partially kept in the cavity surrounded by the slider cover 63 and the top cover 41, and the other part can extend out of the cavity through the strip-shaped slot 631, so as to be pushed by the front door assembly 5 and move along the strip-shaped slot 631. Figure 8 It can be understood that when the front door assembly 5 is closed, it can be kept in the closed state. The way of keeping the front door assembly 5 in the closed state is not limited. For example, a matching buckling structure can be arranged on the front door assembly 5 and the shell 1 respectively. The front door assembly 5 in the closed state is limited on the shell 1 through the buckling structure.

[0071] It can be understood that when the front door assembly 5 is closed, it can be kept in the closed state. The way of keeping the front door assembly 5 in the closed state is not limited. For example, a matching buckling structure can be arranged on the front door assembly 5 and the shell 1 respectively. The front door assembly 5 in the closed state is limited on the shell 1 through the buckling structure.

[0072] As shown in Figure 1 and 3 , and as shown in Figure 10 , the front door assembly 5 is located in front of the shell 1 and comprises a front door 51 and a first magnetic component 14. The upper and lower ends of the first side of the front door 51 are respectively provided with pivot connection holes 52. The front side of the first side plate 11 of the shell 1 is respectively provided with pivot shafts 113. The two pivot shafts 113 are respectively arranged in the two pivot connection holes 52, so that the front door 51 is pivotally connected with the first side plate 11 of the shell 1, and the front door 51 can rotate relative to the first side plate 11. The first magnetic component 14 is arranged in the second side of the front door 51. The front side of the second side plate 12 of the shell 1 is provided with a second magnetic component 53 for attracting the first magnetic component 14. When the front door assembly 5 is closed, the first magnetic component 14 and the second magnetic component 53 are attracted, so that the front door 51 is tightly attached to the front side of the first side plate 11 and the front side of the second side plate 12. For example, the first magnetic component 14 and the second magnetic component 53 can both be magnets.

[0073] As shown in Figure 6 , the front opening of the concave cavity 111 extends upward to the top surface of the first side plate 11 and communicates with the cavity opening of the concave cavity 111, so that the concave cavity 111 forms an open form on the upper side and the front side. As shown in Figure 7 and Figure 8As shown, the tongue 612 is substantially rectangular at the end connected to the bottom 611, and the other end of the tongue 612 away from the bottom 611 is tapered on both sides, i.e. the two sides of the other end of the tongue 612 are inclined surfaces. The structure of the slider 61 in this form, combined with the form of the cavity 111 which is open on the upper side and the front side, makes the closing sequence of the front door assembly 5 and the top cover assembly 4 unrestricted, and whichever one is closed first, the slider 61 (tongue 612) will move towards the sensor 3 and trigger the sensor 3.

[0074] If the top cover assembly 4 is closed first and then the front door assembly 5 is closed, the front door assembly 5 will be tightly attached to the front side of the shell 1 (i.e. the front side of the first side plate 11 and the front side of the second side plate 12) under the action of magnetic attraction, at this time the inner side of the front door assembly 5 will press the slider 61 to move backward (towards the sensor 3), and the slider 61 will trigger the sensor 3.

[0075] If the front door assembly 5 is closed first, the front door assembly 5 will be tightly attached to the front side of the shell 1 under the action of magnetic attraction, and then the top cover assembly 4 is closed, the slider 61 will also be pressed backward due to the counteracting force of the front door assembly 5, and will trigger the sensor 3.

[0076] As shown, Figure 9 The cavity wall 112 corresponding to the front opening of the cavity 111 is inclined, and has the same inclination direction and inclination degree as the lower end of the tongue 612 of the slider 61. The sensor 3 can be a micro switch, which is a contact type switch sensor 3 that needs physical contact to trigger. The micro switch is arranged on the outside of the cavity wall 112, and the contact of the micro switch is inclined upward into the cavity 111 through the slot wall, and corresponds to the inclined surface of the tongue 612 of the slider 61.

[0077] When the trigger mechanism 6 is arranged on the front door assembly 5, the trigger mechanism 6 can be arranged on the inner upper part of the first side of the front door assembly 5 or the inner upper part of the second side of the front door assembly 5, and a cavity 111 is arranged on the front upper part of the first side plate 11 or the second side plate 12 of the shell 1 and extends to the top thereof, when the front door assembly 5 is closed, the slider 61 of the trigger mechanism 6 extends into the cavity 111 and extends upward to the top of the first side plate 11 or the second side plate 12, when the top cover assembly 4 is closed, the inner side of the top cover assembly 4 will push the slider 61 to move downward and trigger the sensor 3 located below the slider 61. That is, when the trigger mechanism 6 is arranged on the front door assembly 5, the position of the sensor 3 is also changed accordingly so as to be triggered by the slider 61.

[0078] In some embodiments, as shown, Figure 4As shown, the snowflake ice making assembly further comprises a water tank 7, which is divided into a water storage cavity 71 and an ice falling cavity 72. The water storage cavity 71 and the ice falling cavity 72 are both open. The bottom of the ice falling cavity 72 is provided with an ice outlet 73. The water tank 7 can be loaded into the shell 1 through the front side opening of the shell 1 and is located below the evaporator 2. The bottom of the water storage cavity 71 of the water tank 7 is placed on the bottom plate 13 of the shell 1, and the bottom plate 13 avoids the bottom of the ice falling cavity 72, so that the ice outlet 73 of the ice falling cavity 72 can directly discharge ice. That is, the bottom plate 13 does not completely cover the bottom of the shell 1, but only closes the rear part of the bottom, and the front part of the bottom is open, so that the ice outlet 73 provided at the ice falling cavity 72 can directly communicate with the outside. When the water tank 7 is loaded and the front door assembly 5 is closed, the inner side of the front door 51 contacts the front of the water tank 7, so that the water tank 7 cannot slide out of the shell 1 to the front door assembly 5. By designing the ice falling cavity 72 on the water tank 7 and providing the ice outlet 73 at the bottom of the ice falling cavity 72, the size of the ice outlet 73 can be changed, so that the hand can be avoided to be inserted into the shell 1. Compared with the complete opening of the front bottom of the shell 1, a larger opening area is formed, and the safety performance can be improved.

[0079] Further, as shown in Figure 4 The opposite sides of the end of the ice falling cavity 72 of the water tank 7 away from the water storage cavity 71 are respectively provided with positioning protrusions 74. That is, the front sides of the water tank 7 are respectively provided with the positioning protrusions 74. As shown in Figure 6 The first side plate 11 and the second side plate 12 of the shell 1 are respectively provided with positioning grooves 114 corresponding to the end of the front side opening. When the water tank 7 is loaded into the shell 1, the two positioning protrusions 74 are respectively and correspondingly clamped into the two positioning grooves 114, so that the water tank 7 is stably fixed on the shell 1. In this way, the stability of the water tank 7 loaded into the shell 1 is further improved.

[0080] Exemplarily, as shown in Figure 4 The positioning protrusions 74 are wedge-shaped structures gradually reduced from the front end to the rear end, and the shapes of the positioning grooves 114 are adapted to the forms of the positioning protrusions 74. In the process of loading the water tank 7 into the shell 1, the positioning protrusions 74 are gradually inserted into the positioning grooves 114. When the water tank 7 is installed in place, the positioning protrusions 74 are all wedged into the positioning grooves 114, so as to ensure the stability of the water tank 7.

[0081] It can be understood that the ice falling cavity 72 of the water tank 7 is actually only a channel through which the scraped snowflake ice flows, and does not play a temporary storage role. The snowflake ice scraped off directly passes through the ice falling cavity 72 and is discharged from the ice outlet 73.

[0082] The bottom of the ice falling cavity 72 can be completely open, and a boss is protruded into the cavity at the front end in the ice falling cavity 72, and the inner side of the boss gradually extends into the ice falling cavity 72 from top to bottom, so that the inner side of the boss forms an inclined surface, see Figure 17The convex platform not only narrows the ice outlet 73 to avoid the hand of the user from reaching in, but also guides the snowflake ice to fall down, so as to achieve the purpose of smooth ice outlet.

[0083] As shown in Figure 6 , the bottom plate 13 is high at the back and low at the front, which is beneficial to the loading of the water tank 7 at least. As shown in Figure 4 , the bottom of the ice falling cavity 72 of the water tank 7 is protruded downward from the bottom of the water storage cavity 71, so that the depth of the water storage cavity 71 is shallower than that of the ice making cavity 70, and the water storage cavity 71 only needs to store the liquid capable of submerging the bottom of the evaporator 2 to ensure the icing effect on the evaporator 2.

[0084] In some embodiments, as shown in Figure 13 , the snowflake ice making assembly further comprises a water tank assembly 8, which is detachably arranged on the top of the top cover 41 of the top cover assembly 4. The water tank assembly 8 comprises a water tank 81, a rubber plug 84, a sealing ball 85 and an elastic member 86. The internal space of the water tank 81 is used for storing the liquid for making snowflakes. As shown in Figure 17 , the water tank 81 has a water outlet 82, the inner wall of the water outlet 82 is provided with a stop platform 83, the rubber plug 84 is arranged at the end (free end) of the water outlet 82 and forms a cavity with the stop platform 83. The rubber plug 84 has a through hole communicating with the cavity. The internal space of the water tank 81 can also communicate with the cavity through the stop platform 83, so that the liquid in the water tank 81 enters the water outlet 82. The stop platform 83 is equivalent to being inwardly contracted from the connection between the water outlet 82 and the water tank 81. The sealing ball 85 and the elastic member 86 are arranged in the cavity, one end of the elastic member 86 abuts against the stop platform 83, and the other end abuts against the sealing ball 85, and the elastic member 86 is used to apply a force to the sealing ball 85 to block the through hole of the rubber plug 84.

[0085] When the rubber plug 84, the sealing ball 85 and the elastic member 86 are taken out, the liquid can be added into the water tank 81 from the water outlet 82, and after the liquid is added, the rubber plug 84, the sealing ball 85 and the elastic member 86 are arranged in the water outlet 82. The sealing ball 85 tightly adheres to the rubber plug 84 under the water pressure in the water tank 81 and the force of the elastic member 86, and blocks the through hole of the rubber plug 84, so as to realize sealing and prevent the liquid in the water tank 81 from flowing out from the water outlet 82 at the bottom of the water tank 81.

[0086] As shown in Figure 4 , the water storage cavity 71 of the water tank 7 is provided with a top rod 75, when the water tank 7 is loaded into the shell 1, the top rod 75 pushes the sealing ball 85 upward through the through hole of the rubber plug 84, so that the sealing ball 85 opens the through hole, and the elastic member 86 is compressed, see Figure 17When the water tank 7 is pulled out from the shell 1, the top rod 75 withdraws the push of the sealing ball 85, and the sealing ball 85 moves downward under the action of the elastic member 86 and blocks the water outlet 82. By means of the top rod 75 arranged on the water tank 7, the opening and closing of the water outlet 82 can be controlled when the water tank 7 is loaded or unloaded, forming a linkage relationship, avoiding the non-timeliness and possible misoperation of manually opening and closing the water outlet 82.

[0087] In some embodiments, as shown in Figure 3 the two ends of the evaporator 2 are respectively rotatably connected with the first side plate 11 and the second side plate 12 of the shell 1 through bearings, so that the evaporator 2 is rotatably arranged at the middle position in the shell 1, and the lower part of the evaporator 2 is located in the water storage cavity 71 and immersed in the liquid in the water storage cavity 71. When the evaporator 2 rotates, the entire outer circumferential surface of the evaporator 2 will be continuously immersed in the liquid, so that the entire outer circumferential surface can be continuously frozen. As shown in Figure 2 and in combination with Figure 17 and Figure 18 , the shell 1 is further provided with a scraper 9 located above the ice falling cavity 72, which is arranged close to the evaporator 2 and used for scraping the ice frozen on the outer circumferential surface of the evaporator 2 to form snowflake ice when the evaporator 2 rotates, and the snowflake ice is discharged from the ice outlet 73 of the ice falling cavity 72.

[0088] For example, as shown in Figures 4 to 6As shown, the first side plate 11 is provided with a first mounting hole 115 penetrating the plate surface, and the second side plate 12 is provided with a second mounting hole 121 penetrating the plate surface, and the axis of the first mounting hole 115 and the second mounting hole 121 are collinear. The bearing includes a first bearing 116 and a second bearing 122, and the first connecting end 21 of the evaporator 2 is arranged on the first mounting hole 115 through the first bearing 116, and the second connecting end 22 of the evaporator 2 is arranged on the second mounting hole 121 through the second bearing 122. The second connecting end 22 of the evaporator 2 penetrates the joint 24 for introducing the refrigerant into the evaporator 2, and the copper pipe 25 for circulating the refrigerant is connected to the joint 24. Specifically, the inner ring of the first bearing 116 is matched with the first connecting end 21 of the evaporator 2 (that is, the inner ring of the first bearing 116 is sleeved on the evaporator 2). The outer ring of the first bearing 116 is matched with the hole wall of the first mounting hole 115, and the inner side of the first bearing 116 is provided with a first sealing ring 118 to form a sealed structure with the evaporator 2 and the first side plate 11, so that the liquid in the shell 1 cannot contact the first bearing 116. The outer side of the first side plate 11 is fixed with a first end cover 117 covering the first mounting hole 115 and contacting the outer side of the first bearing 116, and the position of the first bearing 116 is fixed through the first end cover 117, so that the evaporator 2 and the first bearing 116 cannot move relative to the first side plate 11. The part of the second connecting end 22 of the evaporator 2 extending out of the second mounting hole 121 is sleeved with a right cover 123, and the right cover 123 is sealingly and fixedly connected with the second side plate 12 through a second sealing ring 125. The outer side of the right cover 123 is provided with a second end cover 124 covering the second connecting end 22 of the evaporator 2, and a third sealing ring 126 is arranged between the second end cover 124 and the right cover 123. The second end cover 124 abuts against the third sealing ring 126, so that the second end cover 124, the evaporator 2 and the second side plate 12 form a sealed structure. The second bearing 122 is arranged between the second connecting end 22 of the evaporator 2 and the joint 24, so that the evaporator 2 can rotate relative to the joint 24 and the copper pipe 25. The inner side of the second end cover 124 contacts the second bearing 122 to fix the position of the second bearing 122, so that the second bearing 122 and the evaporator 2 cannot move to the right.

[0089] The embodiment of the present application also provides a snowflake machine. Figures 14 to 18 As shown, the snowflake machine includes a machine body 10, a driving mechanism, a compressor 30, a condenser 40, a control module 50 and the snowflake ice making assembly in any of the above embodiments. The snowflake ice making assembly is arranged on the upper front side of the machine body 10, the driving mechanism is arranged in the machine body 10 and located on the side of the snowflake ice making assembly, the driving mechanism is connected with the evaporator 2 and used for driving the evaporator 2 to rotate. The compressor 30 and the condenser 40 are both arranged in the machine body 10 and sequentially connected with the evaporator 2 to form a refrigeration system; the control module 50 is arranged on the upper front side of the machine body 10 and used for receiving the signal sent by the sensor 3 and controlling the start and stop of the evaporator 2 based on the received signal.

[0090] The driving mechanism can adopt Figure 16 The motor 20 is shown in the figure, the motor shaft 201 of the motor 20 matches with the shaft hole 23 of the evaporator 2, when the motor 2015 starts, the evaporator 2 can be driven to rotate.

[0091] The snowflake machine of the embodiment of the present application can only be started in the state that the top cover assembly 4 and the front door assembly 5 are closed, so that the evaporator 2 and the scraper 9 making snowflake ice are in a closed space, which ensures the safety performance; and after the ice making is finished, the top cover assembly 4 and the front door assembly 5 are opened, which facilitates the cleaning of the inside of the shell 1.

[0092] The working process and principle of the embodiment of the present application are described as follows:

[0093] Before making snowflake ice, first open the front door assembly 5, and push the water tank 7 into the shell 1 from the front side of the shell 1, the tail (rear part) of the water tank 7 first matches with the bottom plate 13 of the shell 1, and moves backward and upward along the bottom plate 13 until the positioning protrusion 74 of the water tank 7 is clamped in the positioning groove 114 of the shell 1, and the installation of the water tank 7 is completed.

[0094] Then, the top cover assembly 4 can be closed first, or the front door assembly 5 can be closed first. When the top cover assembly 4 is closed first, the tongue part 612 of the slider 61 of the trigger mechanism 6 extends into the recess 111, the front side of the tongue part 612 extends out of the front opening of the recess 111 and protrudes from the front side of the first side plate 11, and then the front door assembly 5 is closed, the front door assembly 5 is tightly attached to the front side of the shell 1 under the action of magnetic attraction, at this time, the inner side of the front door assembly 5 will extrude the tongue part 612 of the slider 61 to move backward, the tongue part 612 of the slider 61 contacts the sensor 3, the sensor 3 is triggered and sends a first signal to the control module 50. At the same time, the inner side of the front door assembly 5 contacts the front side of the water tank 7, so that the water tank 7 will not slide out of the shell 1 to the front door assembly 5.

[0095] If the front door assembly 5 is closed first, the front door assembly 5 is tightly attached to the front side of the shell 1 under the action of magnetic attraction, and then the top cover assembly 4 is closed, the tongue part 612 of the slider 61 extends into the recess 111 and has a tendency to extend out of the front opening of the recess 111 under the action of the reset part 64, and extrudes the inner side of the front door assembly 5, the inner side of the front door assembly 5 applies a reverse force to the tongue part 612 of the slider 61, extrudes the tongue part 612 of the slider 61 backward, and contacts the sensor 3, the sensor 3 is triggered and sends a first signal to the control module 50.

[0096] Then the water tank assembly 8 filled with liquid is installed to the installation port 43 of the top cover assembly 4, the sealing ball 85 of the water outlet 82 of the water tank 81 is pushed open by the top rod 75 of the water tank 7, so that the sealing ball 85 cannot tightly contact with the rubber plug 84 to form a seal, and the liquid in the water tank 81 flows from the water outlet 82 to the water storage cavity 71 of the water tank 7. When the liquid in the water storage cavity 71 is flush with the lowest position of the rubber plug 84 (see Figure 17 ), the liquid cannot continue to flow out of the water tank 81. At this time, the evaporator 2 can contact the liquid in the liquid storage cavity of the water tank 7.

[0097] At this time, the snowflake machine is turned on by the control module 50. The control module 50 first detects whether the sensor 3 is triggered. If the sensor 3 is triggered, the compressor 30 and the condenser 40 are started to realize the refrigeration of the evaporator 2, and at the same time, the motor 20 is started to drive the evaporator 2 to rotate. The bottom of the evaporator 2 contacts the liquid in the water storage cavity 71 of the water tank 7, and the liquid is attached to the surface of the evaporator 2 and is made into thin ice. With the rotation of the evaporator 2, the thin ice at the blade position is scraped off by the blade and forms snowflake ice. The snowflake ice passes through the ice outlet 73 of the water tank 7 and falls into the cup, which can be eaten by the user.

[0098] When the ice making is finished, the water tank assembly 8 is taken away from the top of the top cover assembly 4, the front door assembly 5 is opened, and the water tank 7 is pulled out from the front side opening. At this time, the top cover assembly 4 is opened, and the entire cavity in the evaporator 2 and its surrounding shell is exposed, so that the evaporator 2 and its surrounding position can be directly cleaned, which is convenient for the next time of making snowflake ice.

[0099] It can be understood that after the front door assembly 5, the top cover assembly 4, the water tank 7 and the water tank assembly 8 are correctly installed, only the ice outlet 73 of the water tank 7 is connected to the internal ice making position, which can play a good protection role. If the front door assembly 5 or the top cover assembly 4 is opened during the process of making snowflake ice, it will be sensed by the sensor 3, and the machine will immediately stop making snowflake ice, which ensures that the machine has high safety.

[0100] The above description is intended to be illustrative and not limiting, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more solutions thereof) can be used in combination with each other, and the embodiments can be combined with each other in various combinations or arrangements.
