Description

Technical Field

[0001] The present invention relates to the technical field of ice making equipment, and in particular to an ice making device and a refrigerator. Background Art

[0002] With the development of science and technology, human daily necessities are becoming more and more abundant. Ice-making equipment, as an electrical device used by humans to make ice, has become more and more indispensable; especially in summer, users will have the need to use ice cubes to cool drinks.

[0003] At present, in the prior art, preparation equipment, such as refrigerators and ice makers, is generally used in the catering industry on the market, and the household use rate of refrigerators is much higher than that of ice makers. Individual users will not spend money to purchase an ice maker after buying a refrigerator. Usually, users will put plastic, soft glue or other materials into the freezing chamber of the refrigerator, and inject water into the ice mold to make ice cubes by static ice making. Similarly, some ice makers also make ice using a similar static water ice making principle, that is, fill the ice mold with water and place it in the freezing chamber to freeze directly. However, there will be more bubbles in the ice cubes made by the ice maker or refrigerator using such a static ice making method, resulting in poor permeability of the ice cubes, and the ice-cooling time, ice-cooling taste and ice-cooling effect of the ice cubes are greatly reduced, which greatly reduces the user experience. In addition, most ice makers, in order to ensure the permeability of ice cubes, will use the principle of flowing water ice making to make ice, but such ice makers have low ice-making efficiency, which also reduces the user experience.

[0051] Unless otherwise defined, all terms (including technical terms and scientific terms) used in the description of this embodiment have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0052] In the description of the present embodiment, the description with reference to the terms "present embodiment", "present implementation", "variant implementation", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0053] Combine the following Figures 1 to 6 The ice-making device of this embodiment will be described in detail.

[0054] Reference Figures 1 to 6 In this embodiment, the ice-making device includes an ice-making mold 100, a water injection mechanism 200 and a degassing mechanism 300. The ice-making mold 100 is arranged in a space for providing a low-temperature ice-making environment, and an ice-making cavity 110 is provided in the ice-making mold 100; the water injection mechanism 200 includes a water injection pipe 210 and a water delivery pipe 220 both connected to a water supply unit, and the water injection pipe 210 and the water delivery pipe 220 are both used to transport the water of the water supply unit into the ice-making cavity 110; the degassing mechanism 300 is arranged on the water injection pipe 210, and the degassing mechanism 300 includes a degassing membrane 310, and the degassing mechanism 300 is used to remove gas in the water flowing through the water injection pipe 210 through the degassing membrane 310.

[0055] Since the ice-making device of the present embodiment includes an ice-making mold 100, a water injection mechanism 200 and a degassing mechanism 300, the ice-making mold 100 is arranged in a space for providing a low-temperature ice-making environment, the ice-making mold 100 has an ice-making cavity 110, the water injection mechanism 200 includes a water injection pipe 210 and a water delivery pipe 220 both connected to a water supply unit, and the water injection pipe 210 and the water delivery pipe 220 are both used to transport the water of the water supply unit into the ice-making cavity 110, and the degassing mechanism 300 is arranged on the water injection pipe 210, and the degassing mechanism 300 includes a degassing membrane 310, and the degassing mechanism 300 is used to remove the gas in the water flowing through the water injection pipe 210 through the degassing membrane 310. Then, in the process of transporting the water into the ice-making cavity 110 through the water injection pipe 210, the gas in the water will be effectively discharged. Therefore, the present embodiment can ensure the permeability of ice cubes prepared by the ice-making device and improve the user experience.

[0056] Furthermore, the ice-making device of this embodiment uses the degassing mechanism 300 to remove the gas in the water body efficiently and quickly by using the degassing membrane 310 during the process of conveying water to the ice-making cavity 110 in the ice-making mold 100 through the water injection pipe 210. The water body from which the gas has been removed can be quickly and statically formed into ice in the ice-making cavity 110. Compared with the ice-making machine in the prior art that makes ice by using the principle of flowing water to make ice, the efficiency of ice-making can be greatly improved. Therefore, this embodiment can also ensure the efficiency of making ice cubes by the ice-making device at the same time.

[0057] In addition, it should be noted that the degassing membrane 310 has a certain service life and needs to be replaced within a certain period of time, thereby reducing the user experience. In addition to the need to chill directly drinkable beverages or directly edible foods, users also need to chill non-directly drinkable beverages or directly edible foods with packaging, skins, etc., which cannot meet user needs. Therefore, referring to Figure 1 and Figure 4 In this embodiment, the ice-making device includes a switching mechanism 400, which is connected between the water injection pipe 210 and the water supply unit and between the water delivery pipe 220 and the water supply unit, and is used to control the on-off of the water supply unit and the water injection pipe 210 and the on-off of the water supply unit and the water delivery pipe 220.

[0058] Since the ice-making device of this embodiment further includes a switching mechanism 400, the switching mechanism 400 is connected between the water injection pipe 210 and the water supply unit and between the water delivery pipe 220 and the water supply unit, and the switching mechanism 400 is used to control the on-off of the water supply unit and the water injection pipe 210 and the on-off of the water supply unit and the water delivery pipe 220. Furthermore, the ice-making device can make ice cubes with better permeability by controlling the switching mechanism 400 to make the water supply unit and the water injection pipe 210 connected and disconnect the water supply unit and the water delivery pipe 220; and the ice-making device can make ordinary ice cubes by controlling the switching mechanism 400 to disconnect the water supply unit and the water injection pipe 210 and connect the water supply unit and the water delivery pipe 220. In this way, the degassing mechanism 300 that uses the degassing membrane 310 to degas the water body can be stopped, and ordinary ice cubes can also be made. Therefore, this embodiment can ensure the service life of the degassing membrane 310 and the ice-making device, and at the same time meet the user's demand for ordinary ice cubes.

[0059] It should also be noted that the water supply unit can be a water supply unit included in the ice-making device of this embodiment, or it can be an external water supply unit (such as direct drinking water supply equipment, direct drinking water supply interface, etc.) not included in the ice-making device of this embodiment.

[0060] Reference Figure 1 and Figure 4 In this embodiment, the ice-making device further includes a mold turning mechanism 500 and an ice storage box 600. The mold turning mechanism 500 is drivingly connected to the ice-making mold 100, and is used to turn over the ice-making mold 100 to pour ice; the ice storage box 600 is arranged below the ice-making mold 100, and two ice storage chambers 610 separated by a partition 620 are arranged in the ice storage box 600, and the two ice storage chambers 610 are respectively located on both sides of the rotation center axis of the ice-making mold 100.

[0061] It can be understood that when the water in the ice-making mold 100 is degassed by the degassing mechanism 300, and the ice cubes prepared by the ice-making device have better permeability, the mold-turning mechanism 500 is configured to flip to one side, so that the ice cubes with better permeability detach from the ice-making mold 100 through the ice-making port 111 and fall into one of the ice storage chambers 610. At this time, if the user has a demand for high-quality ice cubes, high-quality ice cubes can be taken out from the ice storage chamber 610; and when the water in the ice-making mold 100 is not degassed by the degassing mechanism 300, and the ice cubes prepared by the ice-making device may have poor permeability, the mold-turning mechanism 500 is configured to flip to the other side, so that the ice cubes with possibly poor quality detach from the ice-making mold 100 through the ice-making port 111 and fall into another ice storage chamber 610. At this time, if the user has a demand for ordinary ice cubes, ordinary ice cubes can be taken out from the ice storage chamber 610. The above has brought great convenience to users and greatly improved the user experience.

[0062] Reference Figure 1 and Figure 4 In one implementation of the switching mechanism 400 in this embodiment, the switching mechanism 400 is a three-way valve 410, the water inlet of the three-way valve 410 is connected to the water supply unit, and the two water outlets of the three-way valve 410 are respectively connected to the water injection pipe 210 and the water delivery pipe 220. Therefore, the switching mechanism 400 can control the on-off of the water supply unit and the water injection pipe 210 and the on-off of the water supply unit and the water delivery pipe 220, and realize the preparation of the above-mentioned high-quality ice cubes and ordinary ice cubes.

[0063] In the modified implementation of the switching mechanism 400 in this embodiment, the switching mechanism 400 includes a first two-way valve and a second two-way valve; the first two-way valve is connected between the water supply unit and the water injection pipe 210, and the first two-way valve is used to control the on-off of the water supply unit and the water injection pipe 210; the second two-way valve is connected between the water supply unit and the water delivery pipe 220, and the second two-way valve is used to control the on-off of the water supply unit and the water delivery pipe 220. Thus, the switching mechanism 400 can control the on-off of the water supply unit and the water injection pipe 210 and the on-off of the water supply unit and the water delivery pipe 220, and realize the preparation of the above-mentioned high-quality ice cubes and ordinary ice cubes.

[0064] Reference Figure 1 , Figure 2 and Figure 4 In this embodiment, the ice-making cavity 110 has an ice-making port 111 located at the top thereof; the water injection pipe 210 includes a water delivery section 211 and a water injection section 212. The water delivery section 211 is connected between a water outlet of the three-way valve 410 and the degassing mechanism 300, and the water delivery section 211 is used to deliver the water of the water supply unit to the degassing mechanism 300; the first end of the water injection section 212 is connected to the degassing mechanism 300, and the second end of the water injection section 212 is arranged above the ice-making port 111, and the water injection section 212 is used to deliver the water from the degassing mechanism 300 to the ice-making cavity 110. In this way, the water from the water supply unit can be transported to the degassing mechanism 300, and the water from the degassing mechanism 300 can be transported to the ice-making cavity 110.

[0065] Reference Figure 1 and Figure 4 In this embodiment, the first end of the water supply pipe 220 is connected to the other water outlet of the three-way valve 410, and the second end of the water supply pipe 220 is arranged above the ice making port 111. This is to realize that the water in the water supply unit is delivered to the ice making cavity 110 without being degassed by the degassing mechanism 300.

[0066] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6In this embodiment, the degassing mechanism 300 further includes a shell 320 and a gas extraction component 330 . A water passage chamber 321 and a ventilation chamber 322 are provided in the shell 320, and an exhaust port 323 connected to the ventilation chamber 322 is provided on the shell 320. The water delivery section 211 and the water injection section 212 are both connected to the water passage chamber 321, so that the water of the water supply unit is transported to the water passage chamber 321 and the water in the water passage chamber 321 from which the gas is removed is transported to the ice making chamber 110; the exhaust port 323 is connected to the exhaust port 323, and the exhaust port 330 is used to exhaust the ventilation chamber 322; and the degassing membrane 310 is provided in the shell 320, and the degassing membrane 310 is provided between the water passage chamber 321 and the ventilation chamber 322, and the degassing membrane 310 is used to allow the gas in the water passage chamber 321 to flow through it to the ventilation chamber 322, and the degassing membrane 310 is used to limit the water in the ventilation chamber 322 from flowing through it to the ventilation chamber 322. The degassing mechanism 300 can remove the gas in the water flowing through the water injection pipe 210 through the degassing membrane 310 .

[0067] Reference Figure 1 and Figure 3 In one implementation of the degassing mechanism 300 of the present embodiment, the shell 320 is a hollow columnar structure, the degassing membrane 310 is set as a hollow columnar structure, and the shell 320 is sleeved on the degassing membrane 310 so that the water passage cavity 321 is wrapped around the outer peripheral side of the ventilation cavity 322, thereby forming the water passage cavity 321 and the ventilation cavity 322 of the degassing mechanism 300, ensuring the implementation of the aforementioned degassing process.

[0068] It should be understood that by setting the shell 320 and the degassing membrane 310 as a hollow columnar structure, the time for the water to remain in the degassing mechanism 300 can be guaranteed, so as to ensure the degassing effect of the degassing mechanism 300, and further ensure the permeability of the ice cubes made by the ice-making device, and the shell 320 is set as a columnar structure, so that the shell 320 can have a smaller volume. At the same time, the water passage cavity 321 is wrapped on the outer peripheral side of the ventilation cavity 322, so as to ensure the passage area of ​​gas permeation between the water passage cavity 321 and the ventilation cavity 322, so as to ensure the degassing efficiency of the degassing mechanism 300, and further ensure the preparation efficiency of ice cubes made by the ice-making device.

[0069] Reference Figure 3 In the present embodiment, a water retaining rib 3211 is disposed in the water passage cavity 321 , and the water retaining rib 3211 is spirally disposed around the outer peripheral side of the degassing membrane 310 from one end of the degassing membrane 310 to the other end of the degassing membrane 310 .

[0070] It should be understood that the water retaining rib 3211 can effectively reduce the flow rate of water in the water passage cavity 321, thereby ensuring the degassing effect of the degassing mechanism 300 and further ensuring the permeability of the ice cubes made by the ice-making device.

[0071] In addition, the cross-sectional area of ​​the water retaining rib 3211 is rectangular to ensure the water retaining rib 3211 has a blocking effect on the flow of water.

[0072] In addition, both ends of the water retaining rib 3211 may be connected to both ends of the housing 320 to ensure that the water retaining rib 3211 can be disposed without contact with the degassing membrane 310 .

[0073] Reference Figure 4 and Figure 5 In another implementation of the degassing mechanism 300 of the present embodiment, the degassing membrane 310 is configured as a tubular structure, the water passage cavity 321 is located inside the tubular structure, and the water passage cavity 321 is located outside the tubular structure, thereby constituting the water passage cavity 321 and the ventilation cavity 322 of the degassing mechanism 300 to ensure the aforementioned degassing process.

[0074] Reference Figure 5 In this embodiment, the tube structure is bent and extended in the housing 320. This ensures that the water remains in the degassing mechanism 300 for a certain period of time, thereby ensuring the degassing effect of the degassing mechanism 300 and further ensuring the permeability of the ice cubes made by the ice-making device.

[0075] In this embodiment, the pipe body structure, the water injection section 212 and the water delivery section 211 may be an integrated structure, and the material of the water injection section 212 and the water delivery section 211 may be the same as the material of the degassing membrane 310 .

[0076] Reference Figure 6 In the modified implementation of the degassing mechanism 300 of the present embodiment, the degassing membrane 310 is configured as a plate-like structure. The water passage cavity 321 and the ventilation cavity 322 are located on both sides of the degassing membrane 310, thereby forming the water passage cavity 321 and the ventilation cavity 322 of the degassing mechanism 300 to ensure the above-mentioned degassing process.

[0077] Reference Figure 6 In this embodiment, the longitudinal section of the degassing membrane 310 can be flat, curved or wavy. This ensures that the gas permeation area between the water cavity 321 and the ventilation cavity 322 is sufficient to ensure the degassing efficiency of the degassing mechanism 300, and further ensures the efficiency of ice cubes prepared by the ice making device.

[0078] In this embodiment, a water baffle is arranged in the water passage cavity 321 .

[0079] It should be understood that the water baffle can effectively reduce the flow rate of water in the water passage cavity 321, thereby ensuring the degassing effect of the degassing mechanism 300 and further ensuring the permeability of the ice cubes made by the ice-making device.

[0080] In this embodiment, the material of the degassing membrane 310 includes polyimide, polytetrafluoroethylene and / or polyperfluoroethylene propylene, so that the degassing membrane 310 can allow the gas in the water cavity 321 to pass through it to flow into the ventilation cavity 322 and restrict the water in the ventilation cavity 322 from passing through it to flow into the ventilation cavity 322.

[0081] Reference Figure 1 and Figure 4 In this embodiment, the vacuum assembly 330 includes a vacuum pump 331 and an exhaust pipe 332 connected between the vacuum pump 331 and the exhaust port 323 to achieve vacuuming of the ventilation cavity 322 .

[0082] In this embodiment, the ice-making device can make both ordinary ice and transparent ice, and can store ice independently. The working process of the ice-making device can be:

[0083] When transparent ice is required to be made, the water supply unit and the water injection pipe 210 are connected by the three-way valve 410. The water first passes through the degassing mechanism 300 for degassing, and then enters the ice-making cavity 110 of the ice-making mold 100 through the water injection nozzle 230 to make ice cubes. After ice making is completed, the ice-making mold 100 can rotate clockwise to complete ice removal. Among them, when the water enters the degassing mechanism 300, the vacuum pump 331 starts to work. As the water flows, the bubbles overflow from the degassing membrane 310 under the action of the negative pressure environment. When the pressure in the water-passing cavity 321 reaches the first set pressure value, the pump stops. When it is detected that the pressure in the water-passing cavity 321 is greater than the second set pressure value, wherein the second set pressure value is greater than the first set pressure value, the vacuum pump 331 is restarted until the pressure in the water-passing cavity 321 returns to the first set pressure value again. After repeating the preset number of times, the valve set on the water injection nozzle 230 is opened to perform the water injection and ice-making task. On the contrary, when ordinary ice cubes need to be made, the three-way valve 410 connects the water supply unit and the water delivery pipe 220 to perform the ice making task.
