Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] It should be noted that the terms "set" and "connected" should be understood in a broad sense. For example, they can be directly set and connected, or indirectly set and connected through intermediate components and intermediate structures.

[0029] In addition, in the embodiments of the present invention, if there are terms indicating orientation or positional relationships such as "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., they are based on the orientation or positional relationships shown in the drawings or the conventional placement states or usage states. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the structures, features, devices or elements referred to must have specific orientation or positional relationships, nor must they be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0030] In the specific embodiments, the various specific technical features and each embodiment described can be combined in any suitable manner without contradiction. For example, different embodiments can be formed by combining different specific technical features / embodiments. To avoid unnecessary repetition, various possible combination methods of the specific technical features / embodiments in the present invention will not be described separately.

[0031] An ice maker usually injects water into an ice tray to freeze it into ice. Traditional ice makers usually take out the ice tray for water injection. This process is not only troublesome to operate, but also when the ice tray is put back in place, the water it holds is very likely to spill out due to the shaking of the ice tray.

[0032] For this reason, the present invention provides an ice maker ice tray assembly. This ice maker ice tray assembly is installed on an ice maker and is designed to be able to inject water into the ice tray without taking out the ice tray, thereby saving the cumbersome steps of manually taking and placing the ice tray and improving the convenience of use.

[0033] Refer to Figures 1 to 5 As shown, the ice maker ice tray assembly provided by the present invention includes an ice tray 20, a cover plate assembly 30, and a water delivery system. The ice tray 20 is arranged with ice making grooves 21. The cover plate assembly 30 covers the ice tray 20 to cover the openings of the ice making grooves 21. An injection cavity 34 is formed inside the cover plate assembly 30. An injection hole 311 communicating the injection cavity 34 and the ice making grooves 21 is opened on the surface of the cover plate assembly 30 facing the ice tray 20. The water delivery system is used to deliver water to the injection cavity 34.

[0034] The shape of the ice making grooves 21 arranged on the ice tray 20 can be determined according to the shape of the required ice cubes, such as square, round, heart-shaped, etc., and is not limited here. To prevent impurities such as dust in the air from falling into the ice making grooves 21 and affecting the cleanliness of the ice cubes, the ice tray 20 is covered with a cover plate assembly 30. The cover plate assembly 30 is a cover body with a certain thickness. An injection cavity 34 is formed inside it, and an injection hole 311 communicating the injection cavity 34 and the ice making grooves 21 is opened on the surface of the cover plate assembly 30 facing the ice tray 20.

[0035] The water supply system includes a water pipe 41 and a water pump (not shown in the figure) provided on the water pipe 41. The water pipe 41 can be connected to an external water pipe, or a water storage tank for storing water can be provided in the cabinet 10 of the ice maker 100, and then the water pipe 41 is connected to the water storage tank. In addition, a control valve (not shown in the figure, and the control valve can be an electromagnetic valve, etc.) for controlling the opening and closing of the water pipe 41 can be provided on the water pipe 41. When it is necessary to inject water into the water injection chamber 34, the control valve is opened, and when it is not necessary to inject water into the water injection chamber 34, the control valve is closed. Thus, the water supply system can inject water into the water injection chamber 34 through the water pipe 41. When the water level in the water injection chamber 34 can cover the water injection hole 311, the water in the water injection chamber 34 will flow into the ice making tank 21 through the water injection hole 311. When each ice making tank 21 is filled with water, the overflowing water will flow back into the water injection chamber 34 through the water injection hole 311.

[0036] From the above process, it can be seen that the ice maker 100 adopting this technical solution can complete water injection without removing the ice grid 20. The user only needs to start the water supply system, and the water will automatically flow into the ice making tank 21 through the water injection hole 311, without manually removing and replacing the ice grid 20, greatly simplifying the ice making operation steps and improving the convenience of use.

[0037] In actual application, the ice grid 20 can be horizontally arranged in the cabinet 10 of the ice maker 100, that is, the notch of the ice making tank 21 is vertically oriented. At this time, the cover plate assembly 30 injects water from above the ice grid 20 from top to bottom. When the ice making tank 21 is filled with water, the water in the ice making tank 21 overflows from bottom to top. Or, the ice grid 20 can be vertically arranged in the cabinet 10 of the ice maker 100, that is, the notch of the ice making tank 21 is horizontally oriented, or the orientation of the notch of the ice making tank 21 forms an angle not exceeding 5° with the horizontal direction. At this time, the cover plate assembly 30 injects water into the ice making tank 21 from the side of the ice grid 20. When the notch of the ice making tank 21 is horizontally oriented, the water can flow into the tank in a more stable and gentle manner, thereby reducing the impact force of the water and helping to reduce the possibility of air in the water being stirred to form bubbles, and thus improving the transparency of the ice cubes.

[0038] In an embodiment of the present invention, a water inlet 35 is provided at the top of the water injection chamber 34, and the water delivery pipeline 41 is communicatively connected to the water inlet 35. That is, the water delivery pipeline 41 injects water into the water injection chamber 34 from top to bottom, and the water level in the water injection chamber 34 continuously rises over time. When the water level reaches the height of the water injection holes 311, water will flow into each ice-making groove 21 at the same height through a plurality of water injection holes 311 simultaneously. This waterway design can ensure that the water injection speed and water volume in the ice-making grooves 21 at the same height are consistent, improving the uniformity of water injection. At the same time, the water level in the water injection chamber 34 rises evenly, and the water flows smoothly into the ice-making grooves 21 through the water injection holes 311. This stable water injection method reduces the impact force of the water flow, thereby reducing the possibility of air in the water being agitated to form bubbles, which helps to improve the transparency of the ice cubes.

[0039] Specifically refer to Figure 2 and Figure 5 In an embodiment of the ice grid assembly of this ice maker, a support member 50 is further included. The support member 50 is disposed within the cabinet 10 of the ice maker 100. A placement groove 51 is provided on the side surface of the support member 50, and the ice grid 20 is disposed within the placement groove 51 such that the notch of the ice-making groove 21 faces horizontally. The support member 50 is used to provide physical support for the ice grid 20, providing a stable and precise placement position for the ice grid 20, ensuring that the ice grid 20 always remains stable during the ice-making process, and ensuring that the ice grid 20 always remains horizontally oriented during the ice-making process, avoiding problems such as uneven water injection or inconsistent ice cube formation caused by the inclination or shaking of the ice grid 20.

[0040] Furthermore, a water guide groove 52 is concavely provided at the top of the support member 50. The water guide groove 52 is disposed above the placement groove 51 and is isolated from the placement groove 51, and the water guide groove 52 is communicatively connected to the water inlet 35. The water delivery pipeline 41 includes a water injection section 42. The water injection section 42 straddles the support member 50 and passes through the water guide groove 52. Refer to Figure 6 . Water flow holes 421 are provided on the water injection section 42. The water flow holes 421 are communicatively connected to the notch of the water guide groove 52 such that the water in the water injection section 42 can flow into the water guide groove 52 and then into the water inlet 35 through the water flow holes 421 in sequence. Among them, clamping positions for clamping the water injection section 42 can be provided on the opposite sides of the support member 50 in the water guide groove 52, thereby realizing the limiting installation of the water injection section 42.

[0041] In this embodiment, the water flow holes 421 are communicated with the notch of the water guide groove 52, and the water guide groove 52 is communicated with the water inlet 35, so as to realize the connection between the water delivery pipeline 41 and the water inlet 35. At this time, the water flow path in the ice maker 100 is as follows: the water in the water delivery pipeline 41 flows to the water injection section 42 and then flows into the water guide groove 52 through the water flow holes 421. Then, the water in the water guide groove 52 flows into the water injection cavity 34 through the water inlet 35. The water level in the water injection cavity 34 rises continuously with time. When the water level reaches the height of the water injection holes 311, the water will flow into each ice making groove 21 at the same height through a plurality of water injection holes 311 at the same time. After the ice making grooves 21 are filled with water, the excess water will flow back into the water injection cavity 34 through the water injection holes 311. The water guide groove 52 can buffer the impact force of the water flow. The water flow flows into the water guide groove 52 through the water flow holes 421 and then flows into the water injection cavity 34 from the water guide groove 52. This multi-stage diversion design can make the water flow into the water injection cavity 34 more smoothly, reduce the direct impact of the water flow on the water injection cavity 34, and further reduce the water splash and bubble formation caused by the water flow impact.

[0042] Furthermore, the bottom wall of the water guide groove 52 is provided with a water guiding wall 521, and the water guiding wall 521 is gradually inclined from the end far away from the water inlet 35 to the end close to the water inlet 35. The water guiding wall 521 can be designed as an arc surface with the end far away from the water inlet 35 being high and the end close to the water inlet 35 being low or a slope surface with a linear inclination. Whether it is an arc surface or an inclined slope surface, the inclined design can effectively guide the water flow from the end far away from the water inlet 35 to the end close to the water inlet 35, ensuring that the water flow can smoothly enter the water injection cavity 34 and avoiding the phenomenon of water flow staying or uneven distribution in the water guide groove 52.

[0043] At the same time, in one embodiment, the cover plate assembly 30 is provided with a water guiding surface 36. Refer to Figure 4 or Figure 5 , the water guiding surface 36 is arranged on the side of the water inlet 35 facing away from the water guide groove 52, and the water guiding surface 36 is gradually inclined from the end far away from the water inlet 35 to the end close to the water inlet 35, and the highest point of the water guiding surface 36 is higher than the lowest point of the water guiding wall 521. The water guiding surface 36 and the water guiding wall 521 jointly form a "V"-shaped water flow inlet, that is, the water inlet 35 is arranged at the intersection of the "V"-shaped inlet, which can more effectively concentrate the water flow. And the highest point of the water guiding surface 36 is higher than the lowest point of the water guiding wall 521, so that the water guiding surface 36 can play a role in blocking and guiding the water flow flowing down from the water guiding wall 521, effectively preventing the water flow from overflowing outward and ensuring that the water flow can smoothly flow into the water inlet 35.

[0044] Refer to Figure 4 and Figure 5, in an embodiment of the present invention, the water injection chamber 34 includes a first water injection chamber 341 and a second water injection chamber 342. The second water injection chamber 342 is disposed on a side of the first water injection chamber 341 away from the ice tray 20. The water injection hole 311 is opened on a surface of the first water injection chamber 341 facing the ice tray 20. The water delivery system is used to deliver water to the first water injection chamber 341. Specifically, the water delivery pipeline 41 is communicatively connected to the first water injection chamber 341, that is, the water inlet 35 is opened at the top of the first water injection chamber 341. An overflow channel 37 is provided between the first water injection chamber 341 and the second water injection chamber 342. The overflow channel 37 communicates the top of the first water injection chamber 341 and the top of the second water injection chamber 342. Among them, a water pipe may be connected to the top of the first water injection chamber 341 and the top of the second water injection chamber 342 to form the overflow channel 37; alternatively, an opening may be provided on the partition wall between the first water injection chamber 341 and the second water injection chamber 342 to form the overflow channel 37, which is not limited herein.

[0045] Specifically, the cover plate assembly 30 includes a cover plate 31, a surrounding plate 32, and an overflow bin 33. As Figure 3 , Figure 4 and Figure 5 shown, the cover plate 31 is covered on the ice tray 20 to cover the notch of the ice making groove 21. The water injection hole 311 is opened on the cover plate 31. The surrounding plate 32 is covered on a side of the cover plate 31 away from the ice tray 20. The surrounding plate 32 and the cover plate 31 enclose to form the first water injection chamber 341. The overflow bin 33 is disposed on a side of the surrounding plate 32 away from the cover plate 31. The second water injection chamber 342 is formed in the overflow bin 33. During installation, after the cover plate 31, the surrounding plate 32, and the overflow bin 33 are combined into an integral body and then covered on the ice tray 20, the rapid sealing of the ice making groove 21 can be achieved.

[0046] At this time, the water flow path in the ice maker 100 is as follows: the water in the water delivery pipeline 41 flows to the water injection section 42 and then flows into the water guide groove 52 through the water flow hole 421. Then, the water in the water guide groove 52 flows into the first water injection chamber 341 through the water inlet 35. The water level in the first water injection chamber 341 gradually rises. When the water level rises to the height of the water injection hole 311, the water flows into each ice making groove 21 at the same height through the water injection hole 311. After the ice making groove 21 is filled with water, the excess water will flow back into the first water injection chamber 341 through the water injection hole 311. When the water level in the first water injection chamber 341 continues to rise to the entrance of the overflow channel 37, the excess water will flow into the second water injection chamber 342 through the overflow channel 37. From the above process, it can be seen that the function of the second water injection chamber 342 is to receive the excess water overflowing from the first water injection chamber 341, thereby preventing equipment failures caused by water overflowing from the first water injection chamber 341.

[0047] Furthermore, a water outlet 39 is formed at the bottom of the second water injection cavity 342, and the water outlet 39 is communicated with a water delivery pipeline 41. Thus, after the excess water in the first water injection cavity 341 overflows into the second water injection cavity 342, it will flow back into the water delivery pipeline 41 from the water outlet 39 at the bottom of the second water injection cavity 342, thereby forming a complete water flow circulation system, avoiding waste of water resources, and improving the utilization rate of water resources.

[0048] In an embodiment of the present invention, the cover plate assembly 30 further includes a bushing 38 made of an elastic material. The bushing 38 covers the cover plate 31, and the cover plate 31 is detachably covered on the ice tray 20 through the bushing 38. After the water in the ice-making groove 21 freezes into ice, the ice tray 20 can be opened by peeling the bushing 38 from the ice tray 20, and the ice cubes can be taken out. The material of the bushing 38 is an elastic material, such as rubber and silica gel, etc., which can improve the sealing performance between the cover plate 31 and the ice tray 20, and prevent the water in the ice-making groove 21 from flowing out from the connection between the cover plate 31 and the ice tray 20. In addition, the elastic bushing 38 enables users to easily install the cover plate assembly 30 on the ice tray 20 or remove it from the ice tray 20, reducing the operation time. Meanwhile, the elastic bushing 38 provides a layer of cushioning between the cover plate 31 and the ice tray 20, avoiding direct contact between the ice cubes and the cover plate 31, preventing the ice cubes from adhering to the cover plate 31 during the freezing process, and facilitating the demolding of the ice cubes.

[0049] Specifically, the bushing 38 includes a base 381, a first curled edge 382 and a second curled edge 383 protruding from the edge of the base 381. The base 381 is stacked on the side of the cover plate 31 facing the ice tray 20. An avoidance hole 3811 is formed on the base 381 opposite to the water injection hole 311, so as to ensure that the water in the first water injection cavity 341 can smoothly enter the ice-making groove 21 through the water injection hole 311 and the avoidance hole 3811. The first curled edge 382 protrudes towards the side where the ice tray 20 is located, and the second curled edge 383 protrudes towards the side of the cover plate 31. Both the first curled edge 382 and the second curled edge 383 are annularly arranged. The first curled edge 382 is used to bite the edge of the ice tray 20, and the second curled edge 383 is used to bite the edge of the cover plate 31, thereby realizing the connection between the base 381 and the ice tray 20 and the cover plate 31.

[0050] Refer to Figures 7 to 9Some embodiments of the present invention further include a driving mechanism 60, which is in transmission connection with the cover assembly 30 and is used to drive the cover assembly 30 to approach and move away from the ice tray 20, so that the cover assembly 30 can automatically block and open the ice making groove 21. When ice making is required, the cover assembly 30 moves closer to the ice tray 20, and since the bushing 38 is made of elastic material, the first curling edge 382 can automatically bite the edge of the ice tray 20 to achieve sealing of the ice making groove 21; when ice making is completed, the cover assembly 30 moves away from the ice tray 20, and the first curling edge 382 can automatically break away from the edge of the ice tray 20, thereby opening the ice making groove 21.

[0051] exist Figures 7 to 9 In the illustrated embodiment, the driving mechanism 60 includes a motor 61 and a screw rod 62 driven by the motor 61. The screw rod 62 is disposed in the cover assembly 30 to be transmission-connected with the cover assembly 30. The screw rod 62 drives the cover assembly 30 to move in a direction perpendicular to the ice tray 20 toward or away from the ice tray 20 during rotation, thereby blocking and opening the ice making groove 21. The driving mechanism 60 in this embodiment adopts a motor 61 screw rod 62 transmission structure. When the motor 61 drives the screw rod 62 to rotate in a first direction, the cover assembly 30 moves in a direction toward the ice tray 20, thereby blocking the sealing groove; when the motor 61 drives the screw rod 62 to rotate in a second direction, the cover assembly 30 moves away from the ice tray 20, thereby opening the sealing groove. The motor 61 screw rod 62 transmission structure has high transmission accuracy and stability and is easy to implement.

[0052] Further, the cover assembly 30 may be connected with a sliding guide rail, which is installed at opposite ends of the cover assembly 30 and is slidably connected to the cover assembly 30, and the length direction of the sliding guide rail is consistent with the movement direction of the cover assembly 30. The driving mechanism 60 is transmission-connected to the cover assembly 30, and is used to drive the cover assembly 30 to slide toward or away from the ice tray 20, thereby blocking and opening the notch of the ice making groove. The sliding guide rail provides a stable sliding path for the cover assembly 30, ensuring the linearity and stability of its movement.
