Description

Technical Field

[0001] This invention belongs to the field of ice box technology, and particularly relates to a bottom-heat-conducting ice box and an ice box molding process. Background Technology

[0002] Most existing ice boxes are made of plastic, which has poor thermal conductivity and a long freezing time. The top of the water in the ice box is directly exposed to the low temperature environment, so the ice freezes from the top to the bottom. This causes air bubbles in the water to remain inside the ice, resulting in cloudy ice with low transparency and a poor appearance.

[0003] In recent years, metal ice cube trays have also emerged, offering better thermal conductivity and accelerating freezing. However, the sides and bottom of the ice cube tray dissipate heat, and the top of the water is directly exposed to the low-temperature environment, causing the freezing process to involve heat transfer from the center outwards. This disordered freezing method still results in air bubbles remaining inside the ice, making the ice opaque.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the aforementioned shortcomings, this invention provides a bottom-heat-conducting ice maker, which solves the technical problem that existing ice makers produce ice cubes with air bubbles inside, resulting in low transparency, poor appearance, and negatively impacting user experience.

[0006] To address the aforementioned problems, the present invention provides a bottom-heat-conducting ice maker, comprising a box body, wherein the box body is provided with a plurality of ice trays, and each ice tray forms a cavity for holding liquid; a heat-conducting component is fixed to the bottom of the ice tray. The heat-conducting element is configured to conduct heat from the cavity to the outside of the ice tray, thereby creating a temperature gradient from bottom to top within the cavity.

[0007] According to the bottom heat-conducting ice maker of the present invention, the heat-conducting component is made of copper, aluminum or 304 stainless steel.

[0008] According to the bottom heat-conducting ice maker of the present invention, the heat-conducting component includes a bottom plate; a side plate is formed around the periphery of the bottom plate; a fixing hole is provided on the side plate; and a fixing post that mates with the fixing hole is provided on the outer side wall of the ice tray.

[0009] According to the bottom heat-conducting ice maker of the present invention, there are multiple fixing holes, and the multiple fixing holes are evenly arranged around the central axis of the bottom plate on the side plate.

[0010] According to the bottom heat-conducting ice maker of the present invention, the wall thickness of the ice tray is 2-3 mm, and the wall thickness of the heat-conducting component is 0.5-1 mm.

[0011] According to the bottom-heat-conducting ice maker of the present invention, the heat-conducting component is a heat-conducting plate; the heat-conducting plate is disposed through the bottom of the ice tray.

[0012] According to the bottom-heat-conducting ice maker of the present invention, the heat-conducting component includes a heat-conducting plate and a diffuser plate connected in surface contact; the heat-conducting plate is disposed through the bottom of the ice tray, and the diffuser plate is attached to the outer side of the bottom of the ice tray.

[0013] According to the bottom heat-conducting ice maker of the present invention, the heat-conducting plate and the diffuser plate are fixedly connected by brazing, electric welding or diffusion welding.

[0014] An ice-making box forming process, used for forming ice-making boxes, includes the following process steps: S1, manufacturing heat-conducting components; S2, place the heat-conducting component in the cavity; S3, mold closing; inject molten plastic into the mold cavity; Mold temperature: 80-100°C, injection pressure: 80Mpa-120Mpa, holding time: 8-15 seconds; S4. After cooling, the mold is opened to obtain the ice-making box.

[0015] According to the ice box molding process of the present invention, in step S1, after the heat-conducting component is obtained, the heat-conducting component is cleaned and rust-proofed.

[0016] In summary, the bottom-heat-conducting ice maker of the present invention creates a temperature gradient from bottom to top within the ice compartment by fixing a heat-conducting component at the bottom of the ice tray. This causes the water in the ice tray to freeze sequentially from bottom to top. Air bubbles in the water can escape from the top of the ice compartment, ultimately resulting in ice cubes with high transparency and high density, thus improving the user experience. The present invention also provides an ice maker molding process. Attached Figure Description

Detailed Implementation

[0018] See Figure 1 This invention provides a bottom-heat-conducting ice maker, comprising a box body 1, wherein the box body 1 is provided with a plurality of ice trays 11, and each ice tray 11 forms a receiving cavity 12 for holding liquid; see also Figure 2 and Figure 3 A heat-conducting metal component 2 is fixed to the bottom of the ice grid 11; Preferably, the heat-conducting component 2 of the present invention is made of a material with good thermal conductivity, such as copper, aluminum or 304 stainless steel.

[0019] The heat-conducting element 2 is configured to conduct heat from the cavity 12 to the outside of the ice tray 11, thereby forming a temperature gradient from bottom to top within the cavity 12. After each ice compartment 21 of the ice maker of the present invention is filled with water, the entire ice maker is placed in a low-temperature space and left to stand. The low-temperature space described in the present invention has a temperature below -5°C and can be the freezer compartment of a refrigerator or freezer, or the storage compartment of a cold storage. It can also be placed indoors or outdoors where the ambient temperature is below -5°C.

[0020] The heat-conducting component 2 transfers heat from the water in the receiving cavity 12 to the low-temperature space for dissipation, thereby creating a temperature gradient from bottom to top within the receiving cavity 12. This causes the water in the ice tray 11 to solidify sequentially from bottom to top, allowing air bubbles in the water to escape from the top of the receiving cavity 12, ultimately resulting in ice blocks with high transparency. Because the ice blocks solidify sequentially, they are free of air bubbles and impurities, have good density, and are not easily broken.

[0021] As one embodiment, after the ice cubes have completely solidified, the ice-making box is removed from the low-temperature space. The heat-conducting component 2 has good thermal conductivity and heats up quickly, thereby forming a water film on the contact surface between the heat-conducting component 2 and the water, which facilitates the demolding of the ice cubes and prevents the ice cubes from sticking to the inner wall of the ice tray.

[0022] This invention utilizes a heat-conducting component 2 fixed to the bottom of the ice tray 11. This creates a temperature gradient from bottom to top within the receiving cavity 12, causing the water in the ice tray 11 to solidify sequentially from bottom to top. Air bubbles in the water can escape from the top of the receiving cavity 12, ultimately resulting in ice blocks with high transparency and high density, thus enhancing the user experience.

[0023] See Figure 4As an embodiment of the heat-conducting component 2 of the present invention, the heat-conducting component 2 includes a base plate 21; a side plate 22 is formed around the periphery of the base plate 21; combined with Figure 5 The side plate 22 is provided with fixing holes 23; the outer side wall of the ice tray 11 is provided with fixing posts 13 that cooperate with fixing holes 23; The heat-conducting component 2 is fixed to the bottom of the ice tray 11 by the cooperation of the fixing post 13 and the fixing hole 23. The top surface of the bottom plate 21 is located inside the receiving cavity 12 and directly contacts the water to conduct heat out. The bottom surface of the bottom plate 21 and the side plate 22 are exposed to the low temperature environment to dissipate heat and realize the sequential solidification of the water in the ice tray 11.

[0024] Furthermore, there are multiple fixing holes 23, and the multiple fixing holes 23 are evenly arranged around the central axis of the base plate 21 on the side plate 22.

[0025] As one embodiment, the heat-conducting component 2 in this embodiment is formed by a stamping process, and the fixing hole 23 is formed by a punching method.

[0026] As one embodiment, the wall thickness of the ice tray 11 of the present invention is 2-3 mm; the wall thickness of the heat-conducting component 2 is 0.5-1 mm, preferably 0.7 mm.

[0027] See Figure 6 As one embodiment of the heat-conducting component 2 of the present invention, the heat-conducting component 2 is a heat-conducting plate 24; the heat-conducting plate 24 is disposed through the bottom of the ice tray 11; the top surface of the heat-conducting plate 24 is located inside the receiving cavity 12, directly contacting the water to conduct heat out. The bottom surface of the heat-conducting plate 24 is exposed to the low-temperature environment, dissipating heat and realizing the sequential freezing of the water in the ice tray 11.

[0028] Furthermore, to ensure cooling effect, the area of ​​the heat-conducting plate 24 is not less than 2 / 3 of the bottom area of ​​the ice tray 11.

[0029] See Figure 7 As one embodiment of the heat-conducting component 2 of the present invention, the heat-conducting component 2 includes a heat-conducting plate 24 and a diffuser plate 25 connected in surface contact; the heat-conducting plate 24 is disposed through the bottom of the ice tray 11, and the diffuser plate 25 is attached to the outer side of the bottom of the ice tray 11. The top surface of the heat-conducting plate 24 is located inside the receiving cavity 12, directly contacting the water to conduct heat out. The diffuser plate 25 is exposed to a low-temperature environment, dissipating heat and realizing the sequential freezing of the water in the ice tray 11.

[0030] Optionally, the heat-conducting plate 24 and the diffuser plate 25 are connected by brazing, electric welding or diffusion welding to achieve surface contact and fixation, and the joint has good thermal conductivity.

[0031] The present invention also provides an ice box forming process, comprising the following process steps: S1, manufacture heat-conducting component 2; S2, place the heat-conducting component 2 in the cavity; Optionally, a positioning chamber for accommodating the heat-conducting component 2 is provided in the area of ​​the ice tray 11 formed in the cavity mold; the heat-conducting components 2, which are the same number as the ice tray 11, are placed in the corresponding positioning chambers; S3, mold closing; inject molten plastic into the mold cavity; Mold temperature: 80-100°C, injection pressure: 80Mpa-120Mpa, holding time: 8-15 seconds; S4. After cooling, open the mold to obtain the ice-making box. As one embodiment, in step S1, after the heat-conducting component 2 is obtained, the heat-conducting component 2 is cleaned and rust-proofed; impurities on the surface of the heat-conducting component 2 are removed.

[0032] Furthermore, the heat-conducting component 2 is also subjected to sandblasting or etching treatment; this increases the surface roughness of the heat-conducting component 2 and improves the connection strength with the ice grid 11.

[0033] In summary, this invention provides a bottom-heat-conducting ice maker by fixing a heat-conducting component to the bottom of the ice tray. This creates a temperature gradient from bottom to top within the container, causing the water in the ice tray to freeze sequentially from bottom to top. Air bubbles in the water can escape from the top of the container, ultimately resulting in ice cubes with high transparency and high density, improving the user experience. This invention also provides an ice maker molding process.
