Description

Technical Field

[0001] The invention relates to the technical field of snow and ice machines, and in particular to a top hatch of a household snow and ice machine with a safety protection mechanism. Background Art

[0002] Snow ice machines generally use a compressor refrigeration system to refrigerate the ice roller shaft first. After the ice roller shaft comes into contact with the ice-making liquid in the liquid storage box, an ice film will gradually adhere to its surface. Then the ice roller continues to rotate and comes into contact with the ice-discharging knife group, which scrapes off the ice film to form a slushy-like snow ice product. Home snow ice machines can produce a large amount of snow ice in a short time to meet the needs of use in different scenarios. Home snow ice machines can also increase the fun of family interaction and allow family members to participate in the snow ice making process together.

[0003] In the process of making ice, the ice roller of the existing household snow and ice machine will rotate continuously and keep in close contact with the cutter. The rotation speed of the ice roller and the sharpness of the cutter make this area a potential danger zone. For children who lack safety awareness and self-protection ability, they may inadvertently approach or even touch the running ice roller and cutter out of curiosity. Once this happens, the strong squeezing force and friction between the ice roller and the cutter are likely to cause children to be pinched; secondly, the existing snow and ice machine lacks a protection mechanism. When a child accidentally touches the snow and ice machine and causes the door to open, the ice roller cannot be stopped urgently, so that after the door is opened, the ice roller is still in a rotating state, which greatly increases the risk of accidents, resulting in poor overall safety performance of the snow and ice machine, and unable to provide reliable safety protection for users, especially children. Summary of the invention

[0004] The present invention provides a top hatch of a household snow and ice machine with a safety protection mechanism, so as to solve the problem in the prior art that during the ice making process of the snow and ice machine, due to the lack of a protection mechanism, the ice making roller continues to rotate and contacts the cutter, thereby causing a hidden danger of pinching when children come into contact with the cutter.

[0005] The invention provides a top hatch of a household snow and ice machine with a safety protection mechanism, comprising: a household snow and ice machine body, a device compartment, an ice-making mechanism, an opening and closing device, two protection hatches, and a protection mechanism.

[0006] The device compartment is fixedly mounted on the top of the household snow and ice machine body. The ice-making mechanism is arranged inside the device compartment.

The two sliding blocks are respectively fixedly connected to the two protective hatches.

[0010] According to a top hatch of a household snow and ice machine with a safety protection mechanism provided by the present invention, the driving device includes a motor 2, a gear 1, and a gear 2. One side of the gear 1 is fixedly connected to the output end of the motor 2, and the other side is rotatably mounted on the device bin. The gear 2 is movably sleeved on a bidirectional threaded rod and rotatably connected to the device bin. The gear 1 is meshed with the gear 2.

[0011] According to the top hatch of a household snow and ice machine with a safety protection mechanism provided by the present invention, the transmission device includes two transmission discs and a transmission belt. One of the transmission discs is fixedly connected to the second gear, and the other transmission disc is rotatably connected to the inner wall of the device compartment.

[0012] According to a top hatch of a household snow and ice machine with a safety protection mechanism provided by the present invention, the translation and rotation mechanism includes a moving rod, a first gear, a second gear, and a third gear. The moving rod is movably connected to another transmission plate. The first gear is fixedly connected to the moving rod. The second gear is meshed with the first gear. The third gear is meshed with the second gear.

[0013] According to the top hatch of a household snow and ice machine with a safety protection mechanism provided by the present invention, a connecting plate is fixedly installed on the surface of one of the protection hatches, and the moving rod and the second gear are both rotatably installed on the connecting plate.

[0014] According to the top hatch of a household snow and ice machine with a safety protection mechanism provided by the present invention, connecting strips are fixedly installed on both sides of the surface of the two protection hatches, "T"-shaped sliders are installed at the bottom of the two connecting strips, and "T"-shaped slide plates are fixedly connected to the bottom of the two protection hatches. "U"-shaped plates are installed on both sides of the surface of the device compartment, and the bottom of the inner side of the two "U"-shaped plates is respectively provided with "T"-shaped movable grooves movably connected to the two "T"-shaped slide plates.

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0023] like Figure 1-Figure 3 As shown, the present invention provides a top hatch of a household snow and ice machine with a safety protection mechanism, comprising: a household snow and ice machine body 1, a device compartment 2, an ice-making mechanism 3, an opening and closing device 4, two protection hatches 5, a protection mechanism 6, and two folding dust cover cloths 10.

[0024] The device compartment 2 is fixedly mounted on the top of the household snow and ice machine body 1. The ice-making mechanism 3 is arranged inside the device compartment 2. The ice-making mechanism 3 includes an ice-making roller 31, a rotating rod 32, and an ice scraper 33. The two ends of the rotating rod 32 are rotatably connected to the two sides of the inner wall of the device compartment 2. The ice-making roller 31 is fixedly connected to the rotating rod 32. The ice scraper 33 is arranged at the bottom of the inner cavity of the device compartment 2, and the ice scraper 33 is used to scrape ice from the ice-making roller 31.

[0025] A liquid storage barrel is provided on the top of the household snow and ice machine body 1, and the liquid storage barrel is used to hold ice-making liquid. Before making ice, the user pours an appropriate amount of ice-making liquid into the liquid storage barrel, and the liquid will flow into the liquid storage box specially provided inside the household snow and ice machine body 1 along the diversion channel. Under the action of gravity or a small pressure difference, the ice-making liquid in the liquid storage box continuously flows to the area near the ice-making roller 31, providing convenience for subsequent ice-making operations. The device bin 2 is installed on the household snow and ice machine body 1 to provide installation space for devices such as the ice-making mechanism 3. The ice-making roller 31 is fixedly connected to the rotating rod 32, and the two ends of the rotating rod 32 are respectively rotatably connected to the inner wall of the device bin 2, so that the ice-making roller 31 can rotate as a whole. When the surface of the ice-making roller 31 is refrigerated by the compressor, the low temperature environment causes the surrounding ice-making liquid to gradually condense on its surface, and adhere to form a layer of ice film with uniform thickness. At this time, the ice scraper 33 and the surface of the ice roller 31 are in contact with each other, so that the ice scraper 33 can fully exert its ice scraping function during the rotation of the ice roller 31. Under the relative movement of the two, the ice scraper 33 can effectively scrape off the ice film on the surface of the ice roller 31.

[0026] The opening and closing device 4 is arranged at the top of the inner cavity of the device bin 2. The opening and closing device 4 includes a motor 41, a bidirectional threaded rod 42, two sliding blocks 43, and a limit rod 44. The motor 41 is fixedly mounted on one side of the outside of the device bin 2. One end of the bidirectional threaded rod 42 is fixedly connected to the output end of the motor 41, and the other end is rotatably connected to the inner wall of the device bin 2. The two sliding blocks 43 are both screwed to the bidirectional threaded rod 42. The limit rod 44 is slidably connected to the two sliding blocks 43, and the two ends of the limit rod 44 are respectively fixedly mounted on both sides of the inner wall of the device bin 2. The two sliding blocks 43 are respectively fixedly connected to the two protective doors 5.

[0027] An installation box is provided on the outside of one side of the device compartment 2, and a motor 41 is fixed in the installation box through a mounting structure. The motor 41 is a forward and reverse motor. When the motor 41 is started, it drives the bidirectional threaded rod 42 connected thereto to rotate forward or reverse. Two sliding blocks 43 are respectively screwed on the bidirectional threaded rod 42. Since the bidirectional threaded rod 42 is a double-headed rod structure, when it rotates, it can drive the two sliding blocks 43 to move inward or to both sides at the same time.

[0028] In order to better limit the moving track of the sliding block 43, a limit rod 44 is installed inside the device bin 2. Both ends of the limit rod 44 are firmly supported inside the device bin 2, and the two sliding blocks 43 are sleeved on the limit rod 44. The limit rod 44 can effectively limit the moving position of the sliding block 43, thereby driving the two sliding blocks 43 to move more stably.

[0029] Since the two sliding blocks 43 are fixedly connected to the two protective doors 5 respectively, when the motor 1 41 is started, the opening and closing operations of the two protective doors 5 can be realized by moving the sliding blocks 43. In the closed state, the protective doors 5 can play a protective role when the household snow and ice machine body 1 is in operation, preventing foreign objects from entering the device compartment 2 to interfere with ice making and other related operations.

[0030] The protection mechanism 6 is arranged on the opening and closing device 4. The protection mechanism 6 comprises a driving device 61, a transmission device 62, and a translation and rotation mechanism 63. The driving device 61 is fixedly mounted on one side outside the device bin 2. The transmission device 62 is fixedly connected to the driving device 61. The translation and rotation mechanism 63 is movably connected to the transmission device 62.

[0031] The drive device 61 is installed in an installation box on one side of the device compartment 2, which provides a stable installation environment and effective protection for the drive device 61, thereby preventing damage to the drive device 61 by external dust, water vapor, etc. and extending its service life.

[0032] The main function of the driving device 61 is to drive the transmission device 62 to rotate. When the driving device 61 is started, the power generated by it will be transmitted to the transmission device 62 connected thereto, so that the transmission device 62 starts to operate synchronously. As an intermediate link in power transmission, the transmission device 62 can adjust the power of the driving device 61 according to a certain transmission ratio and transmission mode, and then drive the translation and rotation mechanism 63 to rotate. The translation and rotation mechanism 63 and the transmission device 62 are connected in an active manner. This connection method not only ensures that the power can be effectively transmitted between the two, but also allows the translation and rotation mechanism 63 to move within a certain range. The translation and rotation mechanism 63 is also fixedly connected to one of the protective doors 5. When the protective door 5 is opened and closed, the movement of the protective door 5 will drive the translation and rotation mechanism 63 connected thereto to move on the transmission device 62.

[0033] like Figure 4-Figure 6 As shown, the driving device 61 includes a second motor 611, a first gear 612, and a second gear 613. One side of the first gear 612 is fixedly connected to the output end of the second motor 611, and the other side is rotatably mounted on the device bin 2. The second gear 613 is movably sleeved on the bidirectional threaded rod 42 and rotatably connected to the device bin 2. The first gear 612 is meshed with the second gear 613.

[0034] One side of the motor 2 611 is fixed on the inner wall of the mounting box to ensure that the motor 2 611 remains stable during operation and reduce displacement or damage caused by vibration. Gear 1 612 is tightly fixed to the output end of the motor 2 611. When the motor 2 611 is started, its output shaft will start to rotate, thereby driving the gear 1 612 connected thereto to rotate synchronously. Gear 2 613 is installed above the gear 1 612 and meshes with the gear 1 612. When the gear 1 612 rotates under the drive of the motor 2 611, due to the mutual meshing of the teeth of the two gears, the gear 1 612 will transfer power to the gear 2 613, thereby synchronously driving the gear 2 613 to rotate. This gear transmission method has the advantages of high transmission efficiency and accurate transmission ratio, and can ensure stable transmission of power. On one side of the surface of the gear 2 613, a collar rod is fixedly connected. The collar rod plays a key role in connection and transmission. One end of the bidirectional threaded rod 42 passes through the inside of the collar rod and is connected to the motor 1 41 located outside. Motor 1 41 can drive the bidirectional threaded rod 42 to rotate. The other side of the collar rod penetrates the surface of the device bin 2, extends to the inside of the device bin 2, and is fixedly connected to the transmission device 62. When gear 2 613 rotates under the drive of motor 2 611, it will drive the collar rod to rotate, and then drive the transmission device 62 to operate. In this way, when motor 1 41 is started, motor 1 41 will drive the bidirectional threaded rod 42 to rotate, thereby driving the related mechanisms to operate. When motor 2 611 is started, motor 2 611 will drive gear 1 612, gear 2 613, collar rod and transmission device 62 to operate in turn. Since motor 1 41 and motor 2 611 drive different transmission paths respectively, they can drive two mechanisms to operate independently without interfering with each other, so that the entire device can control the operation of each mechanism according to different needs.

[0035] The transmission device 62 includes two transmission discs 621 and a transmission belt 622. One of the transmission discs 621 is fixedly connected to the second gear 613, and the other transmission disc 621 is rotatably connected to the inner wall of the device bin 2. The transmission belt 622 is slidably connected to the two transmission discs 621.

[0036] Inside the device bin 2, one of the transmission discs 621 is firmly fixed to the extended collar rod. The collar rod is a key component for power transmission, and it introduces the power of the external motor 2 611 into the device bin 2. When the external motor 2 611 starts to operate, the output shaft of the motor 2 611 will generate rotational power. This power is transmitted to the collar rod through a series of transmission components connected to the output end of the motor 2 611, and then drives one of the transmission discs 621 fixed to the collar rod to rotate. The two transmission discs 621 are connected by a transmission belt 622. The transmission belt 622 can transfer power from one transmission disc 621 to another transmission disc 621. When the transmission disc 621 driven by the motor 2 611 rotates, the transmission belt 622 will move with the rotation of this transmission disc 621, thereby transmitting power to the other transmission disc 621, so that the two transmission discs 621 can achieve synchronous rotation.

[0037] The translation and rotation mechanism 63 includes a moving rod 631, a first gear 632, a second gear 633, and a third gear 634; the moving rod 631 is movably connected to another transmission plate 621; the first gear 632 is fixedly connected to the moving rod 631; the second gear 633 is meshed with the first gear 632; and the third gear 634 is meshed with the second gear 633.

[0038] The moving rod 631 can movably penetrate the surface of the other transmission disc 621. In order to achieve effective linkage between the moving rod 631 and the transmission disc 621, four positioning bars are evenly arranged on the outer surface of the moving rod 631. At the same time, four grooves adapted to the positioning bars are opened on the surface of the other transmission disc 621, and these grooves form a sliding connection with the positioning bars. This design enables the moving rod 631 to be synchronously driven to rotate through the cooperation between the positioning bars and the grooves when the other transmission disc 621 starts to rotate under the drive of the transmission belt 622. As the moving rod 631 rotates, the first gear 632 located at one end of it is also synchronously driven to rotate. The second gear 633 is meshed with the first gear 632. According to the principle of gear transmission, when the first gear 632 rotates, its teeth interact with the teeth of the second gear 633, thereby driving the second gear 633 to rotate with the first gear 632. The third gear 634 is firmly fixed on the rotating rod 32, and the rotating rod 32 is fixedly connected to the ice making roller 31. When the second gear 633 rotates, it meshes with the third gear 634 and transmits the rotational force to the third gear 634. Since the third gear 634 and the rotating rod 32 are integrated, the force is further transmitted to the rotating rod 32, driving the rotating rod 32 to rotate. The rotation of the rotating rod 32 eventually drives the ice-making roller 31 to rotate, so that the ice-making roller 31 can continuously perform the ice-making operation.

[0039] The two protection doors 5 are fixedly mounted on the opening and closing device 4. A connecting plate is fixedly mounted on the surface of one of the protection doors 5. The moving rod 631 and the second gear 633 are both rotatably mounted on the connecting plate.

[0040] The two protective doors 5 are both mounted on the opening and closing device 4. When the opening and closing device 4 is started, the two protective doors 5 are driven to open or close. During the ice-making process, the ice-making roller 31 will rotate continuously and keep in contact with the ice scraper 33. The rotation speed of the ice-making roller 31 and the sharpness of the ice scraper 33 form a certain dangerous area between them. If there is no protection of the protective door 5, children may accidentally touch this area and are likely to be pinched by the rotating ice-making roller 31 and the sharp ice scraper 33, thereby causing serious harm to the child's body. In addition, the closing of the protective door 5 can also play a role in preventing dust and foreign objects from entering. During the ice-making process, if dust and debris from the outside enter the interior of the household snow and ice machine body 1, they may adhere to the ice-making roller 31 or other components, affecting the ice-making effect and the service life of the machine. When the protective door 5 is closed, it can effectively block these dust and debris to ensure the cleanliness of the ice-making environment and the normal operation of the machine.

[0041] like Figure 7 As shown, connecting strips 51 are fixedly installed on both sides of the surface of the two protective hatches 5, "T"-shaped sliders 52 are installed at the bottom of the two connecting strips 51, and "T"-shaped slide plates 53 are fixedly connected to the bottom of the two protective hatches 5. "U"-shaped plates 8 are installed on both sides of the surface of the device compartment 2, and the bottom of the inner side of the two "U"-shaped plates 8 is respectively provided with "T"-shaped movable grooves 9 movably connected to the two "T"-shaped slide plates 52. A bottom plate 7 is fixedly installed on one side of the surface of the household snow and ice machine body 1. The inside of the bottom plate 7 is provided with a "T"-shaped slide groove slidably connected to the two "T"-shaped slide plates 53.

[0042] The design of the two protective doors 5 fits the appearance of the household snow and ice machine body 1, and its installation can play a protective role when the ice-making roller 31 and the ice scraper 33 are in operation to make ice. The connecting strip 51 installed on the two protective doors 5 can fit the inner side of the two "U"-shaped plates 8 and move. When the opening and closing device 4 drives the two protective doors 5 to open and close, the connecting strip 51 moves accordingly, and the "T"-shaped slider 52 at the bottom of the connecting strip 51 can just move in the "T"-shaped moving groove 9 opened on the "U"-shaped plate 8, which limits the overall movement of the connecting strip 51 and makes its movement more stable. In addition, when the two protective doors 5 open and close, the "T"-shaped slide plate 53 at the bottom thereof will slide synchronously in the "T"-shaped slide groove opened on the bottom plate 7, further enhancing the stability of the movement of the two protective doors 5.

[0043] like Figure 8As shown, one side of the foldable dust cover cloth 10 is respectively installed on one side of the inner wall of the two "U"-shaped plates 8, and the other side is fixedly connected to the two connecting strips 51. The two foldable dust cover cloths 10 are made of cloth with good folding performance, which can not only effectively prevent external dust from entering the interior of the household snow and ice machine, protect the device components from dust pollution, but also ensure smooth folding and unfolding operations during the opening and closing of the protective door 5. When the opening and closing device 4 is started to drive the two protective doors 5 to open and close, the connecting strip 51 installed on the protective door 5 will move accordingly. The connecting strip 51 is connected to the foldable dust cover cloth 10, so it will drive the foldable dust cover cloth 10 to fold, shrink or unfold. In the process of opening the protective door 5, the connecting strip 51 gradually moves to both sides, and the foldable dust cover cloth 10 is also pulled open and unfolded. When the protective door 5 is closed, the connecting strip 51 moves closer to the middle, and the foldable dust cover cloth 10 is compressed and folded.

[0044] In addition, when the connecting strip 51 moves to drive the "T"-shaped slider 52 to move in the "T"-shaped moving groove 9, the folding process of the folding dust cover cloth 10 will be more stable. The cooperation between the "T"-shaped slider 52 and the "T"-shaped moving groove 9 provides precise guidance and limit for the movement of the connecting strip 51, so that the connecting strip 51 can smoothly drive the folding dust cover cloth 10 to fold and unfold, avoiding jamming, offset, etc. during the folding process, and ensuring the reliability and stability of the folding dust cover cloth 10 during the protection process.

[0045] A collection box 11 is movably installed inside the household snow and ice machine body 1, and handles 12 are respectively installed on both sides of the outside of the collection box 11. The collection box 11 is used to collect the ice produced during the ice making process, and the user can take out the collection box 11 as a whole by holding the two handles 12.

[0046] A hollow column 13 is connected to one side of the device compartment 2. One end of the moving rod 631 moves inside the hollow column 13. The hollow column 13 is a hollow structure, which is installed on the device compartment 2. When one of the protective doors 5 moves, it will drive the moving rod 631 to move inside the hollow column 13, so that the coordination between the structures is more flexible.

[0047] The working principle of the top hatch of the household snow and ice machine of this embodiment is as follows: when the ice machine is in use, the two protective hatches 5 are in a closed state, and the user starts the motor 2 611 through the control terminal. The motor 2 611 starts to operate and drives the gear 1 612 connected thereto to start rotating. Since the gear 1 612 and the gear 2 613 are meshed with each other, the rotation of the gear 1 612 will drive the gear 2 613 to rotate synchronously. The rotation of the gear 2 613 will then drive one of the transmission discs 621 fixedly connected thereto to rotate. The rotational motion of this transmission disc 621 is transmitted to the other transmission disc 621 through the transmission belt 622, so that the moving rod 631 rotates, and the first gear 632 at one end of the moving rod 631 also rotates accordingly. The first gear 632 and the second gear 633 are meshed with each other, so the rotation of the first gear 632 will drive the second gear 633 to rotate. The second gear 633 is meshed with the third gear 634 on the rotating rod 32, thereby driving the third gear 634 to rotate. At this time, the rotation of the rotating rod 32 will cause the ice roller 31 to rotate continuously. During the rotation of the ice roller 31, its surface contacts the surrounding low-temperature environment, and the ice-making liquid gradually condenses on the surface of the ice roller 31, attaching to form an ice film. As the ice roller 31 rotates continuously, the ice film contacts the ice scraper 33, and the ice scraper 33 scrapes off the ice film to form ice smoothie, which falls into the collection box 11 below for collection. When the two protective doors 5 are opened, the motor 1 41 operates to drive the bidirectional threaded rod 42 to rotate, and the two sliding blocks 43 move to both sides at the same time, and the protective doors 5 connected to the two sliding blocks 43 will also open to both sides synchronously. When one of the protective doors 5 is opened, it will drive the second gear 633 to slowly disengage from the third gear 634. Once the second gear 633 is separated from the third gear 634, the third gear 634 will lack the driving force from the second gear 633, and the rotating rod 32 will not be able to continue to rotate, thereby realizing the emergency stop of the rotating rod 32. By setting up the protection mechanism 6, when the two protective doors 5 are opened, whether it is normal maintenance operation or accidental touch by a child, the protection mechanism 6 can make the ice-making roller 31 stop urgently while the protective doors 5 are opened, effectively reducing the accidental risk caused by the continuous rotation of the ice-making roller 31 when the protective doors 5 are opened, ensuring the safety of users when the doors are open, and greatly improving the safety protection effect of household snow and ice machines.
