Description

Technical Field

[0001] This utility model relates to the field of ice boxes, specifically to a pressing structure and its ice box. Background Technology

[0002] Ice cubes are commonly used for cooling or making iced drinks, and the process of making ice cubes often requires an ice maker. An ice maker is a common household tool, typically consisting of a shell and an ice tray mold. The ice tray mold is used to hold water and place it in the freezer compartment of a refrigerator to freeze the water into ice cubes. However, existing ice tray molds have a problem: after multiple ice cubes are frozen in the mold, they usually require repeated squeezing of the mold to fit the desired position and remove them. This increases the repetitiveness and time required for the operation. Furthermore, this method involves direct contact between the user and the ice tray mold, and the uncertainty of the squeezing force makes the mold prone to deformation or even damage under external force.

[0003] Consequently, many types of press-type ice makers have emerged on the market. These makers use a pressing mechanism on their base to remove multiple ice cubes from the ice tray mold with a single press. While offering widespread convenience, they also have drawbacks. Most existing press-type ice makers typically use a one-piece molded or injection-molded shell with a certain elastic modulus that contacts the bottom of the ice tray mold for pressing. On one hand, with a one-piece molded shell, the user's limbs are in direct contact with the shell surface during pressing. Due to the uncertainty of manual pressing pressure, the shell is prone to damage after repeated pressing over a long period, resulting in a relatively short lifespan. On the other hand… In terms of the pressing structure using injection-molded shells, they usually have high hardness, and users often experience a certain impact force during the pressing process, which can easily cause discomfort. At the same time, due to the inherent characteristics of the two types of shells, users usually use their palms to cover and press during the pressing process. For ice cubes that are not demolded after one press, users also need to have certain operating skills during the pressing process, which is not convenient for local adjustments and increases the discomfort during operation. In addition, when some molding molds such as ice tray molds or silicone pads are matched with injection molds such as shells, interference fits often occur, which can easily lead to gaps or unstable sealing or connection at the connection points.

[0004] Based on this, the present invention proposes a pressing structure and its ice maker to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings in the prior art and to provide a pressing structure and its ice maker that has a reasonable structural design, a more compact and stable fit, and can reduce discomfort during operation.

[0006] The technical solution adopted by this utility model to solve the above problems is: a pressing structure, including a movable pressing plate and a silicone pad. The silicone pad is interference-fitted with the pin hole of the movable pressing plate through a pin shaft. The side wall of the pin shaft is provided with an air vent groove. The air vent groove extends from the top of the pin shaft along the axial direction on the side, and the root side wall of the pin shaft is completely in contact with the wall surface that matches the pin hole.

[0007] Furthermore, at least two sets of the venting grooves are provided symmetrically on the sidewalls or at equal intervals relative to the axis.

[0008] Furthermore, the outer wall surface of the silicone pad is flat, and its inner wall surface is provided with multiple sets of mesh grooves.

[0009] Furthermore: the upper and lower sides of the pin hole are provided with reinforcing ribs to divide the movable pressing plate into two sets of symmetrical groove cavities, and the groove cavities are appropriately fitted with mesh grooves.

[0010] Furthermore: A pressing structure and its ice maker, comprising an ice maker, a base, and a pressing part formed by the pressing structure, wherein the ice maker is provided with a plurality of ice cube slots, the bottom of the ice cube slots is made of a flexible material, the ice maker is adapted and fixed on the base from one side, and the movable pressing plate of the pressing part is slidably disposed on the other side of the ice maker and is provided with a number of contact parts adapted to the ice cube slots and in contact with the flexible bottom of the ice cube slots.

[0011] Furthermore: the seat body is provided with a window, and the two sides of the window are provided with limiting guide blocks. The movable pressing plate is provided with a groove to slide and adapt to the limiting guide blocks, and the end of the limiting guide blocks is provided with a limiting protrusion.

[0012] Furthermore, the upper end face of the limiting protrusion is an arc-shaped guide surface.

[0013] Furthermore, the inner end face of the limiting guide block is set as an outward inclined surface in the pressing direction of the movable pressing plate.

[0014] Furthermore, the outer opening of the ice maker is fitted with a lid.

[0015] Furthermore, a rubber strip is provided at the corner of the lower edge of the outer edge of the ice maker to ensure an interference fit with the base.

[0016] Compared with the prior art, this utility model has the following advantages and effects:

[0017] The venting groove described in this invention allows air compressed by the pin in the pin hole to be discharged during the insertion of the silicone pad and the movable pressing plate. This venting groove extends from the top of the pin towards the side of the axis and ensures complete contact between the side wall of the pin root and the wall of the pin hole, resulting in a more precise fit. This makes the connection between the silicone pad and the movable pressing plate, made of different materials, smoother and more stable under the action of the venting groove. It also reduces the likelihood of interference fits or clearance fits that could cause noticeable gaps between the silicone pad and the movable pressing plate, affecting usability and operational comfort. This pressing structure, with a silicone pad connected to the movable pressing plate, reduces operational discomfort and increases operational comfort. It also provides a certain cushioning effect, initially reducing the impact force generated during pressing and further preventing deformation or even damage to the pressing structure and ice box shell caused by excessive force, thus appropriately extending their service life. In addition, the detachable connection between the silicone pad and the movable pressing plate provides a more stable connection and facilitates the installation, removal, replacement, and cleaning of the silicone pad, improving operational convenience while also providing a certain decompression effect.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0025] See Figure 1-3 This embodiment relates to a pressing structure and its ice box 3, including a movable pressing plate 1 and a silicone pad 2. The silicone pad 2 is interference-fitted with the pin hole 11 of the movable pressing plate 1 via a pin 21. The side wall of the pin 21 is provided with a venting groove 211. The venting groove 211 extends from the top of the pin 21 along the axial direction on the side, and the root side wall of the pin 21 is in complete contact with the wall surface that matches the pin hole 11.

[0026] Specifically, in this embodiment, this pressing structure further improves upon the existing pressing structure of the press-type ice maker 3. The silicone pad 2 is fitted and inserted into the pin hole 11 provided on the movable pressing plate 1 via a pin shaft 21. Figure 2 As shown, during the insertion process, the side wall of the pin 21 of the silicone pad 2 is provided with a venting groove 211. This venting groove 211 allows air compressed by the pin 21 in the pin hole 11 to be discharged during the insertion of the silicone pad 2 and the movable pressing plate 1. The air extends from the top of the pin 21 towards the axial direction through the venting groove 211, ensuring complete contact between the side wall of the pin root and the wall of the pin hole 11. This makes the fit between the pin 21 and the pin hole 11 more precise, resulting in a smoother and more stable connection between the silicone pad 2, made of different materials, and the movable pressing plate 1 under the action of the venting groove 211. It also reduces the likelihood of interference fits or clearance fits that could cause noticeable air leakage between the silicone pad 2 and the movable pressing plate 1. The gaps between the silicone pads and the movable press plate 1 prevent the use of the product from being too large, which could affect the comfort of operation. This pressing structure, with the silicone pad 2 connected to the movable press plate 1, reduces discomfort and increases comfort, while also providing a cushioning effect. This initially reduces the impact force generated during pressing, further preventing deformation or damage to the pressing structure and the ice container 3 shell due to excessive force, thus extending their service life. Furthermore, the detachable connection between the silicone pad 2 and the movable press plate 1 provides a more stable connection and facilitates the installation, removal, replacement, and cleaning of the silicone pad 2, improving ease of operation and providing a certain decompression effect.

[0027] The vent grooves 211 are arranged in at least two sets symmetrically or at equal intervals relative to the axis on the side wall. The multiple sets of vent grooves 211 arranged on the side wall of the silicone pad 2 pin 21 can further reduce the external force required for the connection between the pin 21 and the pin hole 11, ensuring the connection stability while further improving the fit between the pin 21 and the pin hole 11, facilitating the installation and disassembly of the silicone pad 2. In addition, the multiple sets of vent grooves 211 have a certain buffering effect, which can further reduce the probability of cracking or even damage to the pin hole 11 of the movable pressing plate 1 due to excessive force or long-term use, further reduce the wear of the pin hole 11, and appropriately extend its service life.

[0028] The outer wall of the silicone pad 2 is flat, and the inner wall is provided with multiple sets of grid grooves 22. The multiple sets of grid grooves 22 make the structure of the silicone pad 2 more compact, further improve the shock absorption performance of the silicone pad 2 and appropriately extend its service life. At the same time, the pressing position can also be adjusted according to different grooves of the grid grooves 22, which not only facilitates operation but also increases the comfort of operation and adds fun to operation.

[0029] The pin hole 11 is reinforced with ribs 111 on its upper and lower sides, dividing the movable pressing plate 1 into two sets of symmetrical grooves 12. Mesh grooves 22 are fitted into the grooves 12. The movable pressing plate 1 is fitted into the grooves 12 and the mesh grooves 22 on its silicone pad 2, further improving the fit between the silicone pad 2 and the movable pressing plate 1, and also expanding the adjustment range of the pressing position of the silicone pad 2 during the pressing process. The fitted connection between the mesh grooves 22 and the grooves 12 further improves the stability and adaptability of the connection, and facilitates adjustment of different pressing positions, improving the accuracy of the pressing position. In addition, the reinforcing ribs 111 further improve the overall structural strength of the movable pressing plate 1, reducing the probability and frequency of damage while improving the stability of use.

[0030] See Figure 3-4A pressing structure and its ice maker 3 are disclosed. The ice maker 3 includes an ice maker 3, a base 4, and a pressing part formed by the pressing structure. The ice maker 3 is provided with a plurality of ice cube slots 31. The bottom of each ice cube slot 31 is made of a flexible material with a flexible bottom 311. The ice maker 3 is adapted and fixed to the base 4 from one side. The movable pressing plate 1 of the pressing part is slidably disposed on the other side of the ice maker 3 and is provided with a number of contact parts 13 adapted to the ice cube slots 31, which contact the flexible bottom 311 of the ice cube slots 31. During use, the ice maker 3 can be frozen by injecting an appropriate amount of water into its plurality of ice cube slots 31 and placing it in the freezer compartment of a refrigerator. The frozen ice cubes in the plurality of ice cube slots of the ice maker 3 can be moved and pressed by pressing the pressing part. The plate 1 slides on its base 4. During the sliding process, the contact part 13 of the movable pressing plate 1 contacts the flexible bottom 311 of the ice cube slots 31 of the ice box 3, which are adapted to the number of ice cube slots 31 on the ice box 3, and causes the flexible bottom 311 of the ice cube slots 31 to deform appropriately, thereby removing the ice cubes in the ice cube slots 31 on the ice box 3. This pressing structure and the ice box 3 facilitate the removal of ice cubes, while the pressing part can improve the comfort during the pressing process. In addition, during the pressing process at different pressing positions, the ice cubes in the ice cube slots at the adapted positions in the ice box 3 can be removed through the grid groove 22 set on the silicone pad 2 of the pressing part and the contact part 13 on the movable pressing plate 1, which facilitates local pressing and adjustment to meet different usage conditions and needs.

[0031] The seat 4 is provided with a window 41, and limiting guide blocks 411 are provided on both sides of the window 41. The movable pressing plate 1 is provided with a groove to slide and adapt to the limiting guide block 411. The end of the limiting guide block 411 is provided with a limiting protrusion 412. The pressing part is placed at the window 41 of the seat 4 for adaptation and sliding. At the same time, during the sliding process of the pressing part, it slides along the limiting guide block 411 through the groove provided on the movable pressing plate 1. It stops sliding at the limiting protrusion 412 at the end of the limiting guide block 411. The limiting guide block 411 and the limiting protrusion 412 can further limit the sliding range of the pressing part on the seat 4, further avoiding the deformation or even damage of the pressing part, the seat 4 and the flexible bottom 311 of the ice box 3 caused by excessive force from the user, and appropriately extending its service life.

[0032] The upper end face of the limiting protrusion 412 is an arc-shaped guide surface 413. The arc-shaped guide surface 413 on the upper end face of the limiting protrusion 412 can facilitate the installation and disassembly of the movable pressing plate 1 of the pressing part, and further reduce the wear and tear on the limiting protrusion 412 caused by the movable pressing plate 1 during its installation process and the probability of damage, thus playing a certain guiding and protective role.

[0033] The inner end face of the limiting guide block 411 is set outwardly at an angle in the pressing direction of the movable pressing plate 1. This setting of the limiting guide block 411 allows the movable pressing plate 1 to have a certain amount of room to move when the pressing part is pressed, so that it can be tilted to a certain extent according to different pressing positions, so that the corresponding ice cubes in the ice tray groove on the ice box 3 can be demolded. This allows the pressing part to be flexibly adjusted, improving the efficiency of ice cube removal and further facilitating the installation and disassembly of the pressing part, thus improving the ease of use.

[0034] The ice maker 3 has a cover 5 fitted to its outer opening. The cover 5 fits over the ice maker 3 via its outer edge 32, ensuring a certain degree of airtightness. This allows users to easily move and adjust the ice maker 3 to different positions after filling it with water, and effectively reduces water leakage during movement. The cover 5 also facilitates the storage and retrieval of ice cubes after demolding in the ice tray, improving usability. Furthermore, the cover 5 is made of any transparent material, such as glass or acrylic, allowing for easy observation and adjustment of the ice cube forming process within the ice tray. This provides both convenience and a strong visual appeal, enhancing the aesthetics of the ice maker 3.

[0035] A rubber strip 321 is provided at the corner of the lower end face of the outer edge 32 of the ice maker 3, which is interference-fitted with the base 4. The ice maker 3 can be detachably connected to the base 4 through the rubber strip 321 provided at the corner of the lower end face of its outer edge 32. The ice maker 3 and the base 4 can be installed and removed under a certain external force through the rubber strip 321. The rubber strip 321, which is interference-fitted with the base 4, can ensure the connection stability between the ice maker 3 and the base 4, and reduce the wear at the edge connection of the base 4 during long-term use, thereby improving the stability and durability of use.

[0036] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
