Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment with an ice-making device. Background Art

[0002] An ice-making device is arranged in a refrigerator to provide ice cubes for users, and is favored by more and more consumers. At present, the ice cubes made by the ice-making device contain a large amount of bubbles, resulting in low transparency of the ice cubes.

[0003] The reason why there are bubbles in the ice cubes made by the ice-making device is that the water used to make ice in the ice-making device starts to freeze from the four sides first. As the temperature drops, the solubility of the gas in the water decreases, and the gas in the water gradually precipitates out. However, the gas cannot be discharged to the outside of the ice layer, and thus gradually condenses in the form of bubbles in the core of the ice cube, causing the ice cube to appear milky white.

[0062] In some embodiments of the present application, a refrigeration device is provided, which is used to provide a low-temperature storage space to meet the low-temperature storage needs of items.

[0063] Figure 1 FIG. 1 is an embodiment of a refrigeration device, such as Figure 1 The picture shows an upright refrigerator, combined with Figure 2 , which includes a box body 100, an inner tank 200, a door body and the like.

[0064] The box body 100 forms the outer contour of the refrigeration device, and the box body 100 is in a rectangular parallelepiped shape.

[0065] The inner liner 200 is disposed in the box body 100 , and the inner liner 200 forms a low-temperature storage space for storing items.

[0066] The low temperature storage space includes at least a refrigerating chamber 210, and the temperature of the refrigerating chamber 210 is higher than zero degrees. The refrigerating chamber 210 is divided into a plurality of compartments by partitions to meet the requirements of zoning storage of items. Drawers may be provided in some compartments.

[0067] The low-temperature storage space further includes a freezer compartment 220 , and the temperature of the freezer compartment 220 is below zero degrees. A drawer may be provided in the freezer compartment 220 .

[0068] The refrigerating chamber 210 and the freezing chamber 220 are arranged vertically, and the refrigerating chamber 210 is arranged above the freezing chamber 220 .

[0069] The door body includes a refrigerating door body 310 and a freezing door body 320. The refrigerating door body 310 is used to close or open the refrigerating chamber 210. The freezing door body 320 is used to close or open the freezing chamber 220.

[0070] In some embodiments of the present application, the refrigeration equipment is air-cooled refrigeration, including a compressor, an evaporator, a condenser, a throttling device, etc.

[0071] An air duct is arranged on the back side of the inner tank 200, and the evaporator is arranged in the air duct. A refrigeration air outlet (not shown) is arranged on the wall of the refrigeration chamber 210, and a freezing air outlet (not shown) is arranged on the wall of the freezing chamber 220, and both the refrigeration air outlet and the freezing air outlet are connected to the air duct.

[0072] The gas flows through the air duct, exchanges heat with the evaporator, and becomes cold air. The cold air flows into the refrigerating chamber 210 through the refrigerating air outlet to adjust the temperature of the refrigerating chamber 210. The cold air flows into the freezing chamber 220 through the freezing air outlet to adjust the temperature of the freezing chamber 220.

[0073] In some embodiments of the present application, the refrigeration equipment further includes an ice-making device, which makes ice through the ice-making device to provide ice cubes for users.

[0074] The ice cubes made by the existing ice-making device contain bubbles. The reason is that the water used for making ice in the ice-making device starts to freeze from the four sides first. As the temperature drops, the solubility of the gas in the water decreases, and the gas in the water gradually precipitates. However, the gas cannot be discharged to the outside of the ice layer, and thus gradually condenses in the form of bubbles in the core of the ice cube, causing the ice cube to appear milky white.

[0075] In order to solve the above problems, in some embodiments of the present application, the ice-making device is improved to obtain ice cubes without bubbles.

[0076] In order to obtain ice cubes without bubbles, the present embodiment pre-treats the water used by the ice-making device for ice-making. Specifically, the water used for ice-making is first depressurized and cooled to precipitate the gas in the water. The water after the gas is precipitated is then used to make ice, thereby obtaining ice cubes without bubbles and with high transparency.

[0077] Decompression treatment of water used for ice making can reduce the solubility of gas in water, thereby causing the gas in the water to precipitate.

[0078] Cooling the water used to make ice can reduce the solubility of gases in water, thereby causing the gases in the water to precipitate.

[0079] When cooling the water for ice making, it is necessary to ensure that the water temperature remains above zero degrees to prevent the water from freezing.

[0080] In some embodiments of the present application, the ice-making process of the ice-making device is divided into a water pretreatment stage and an ice-making stage, and the water pretreatment stage is performed before the ice-making stage.

[0081] That is to say, the water used for ice making is first pretreated. The pretreatment includes reducing the pressure and temperature of the water to reduce the solubility of the gas in the water and precipitate the gas in the water. The water after the gas is precipitated is then used to make ice, and ice cubes with no bubbles and high transparency can be obtained.

[0082] In some embodiments of the present application, refer to Figure 4 The ice making device includes an ice making component 400. The ice making component 400 is an ice making body and is used for making ice, that is, making ice cubes using water.

[0083] This embodiment does not limit the specific structure of the ice-making component 400. Water for ice-making enters the ice-making component 400, and the ice-making component 400 makes ice cubes from the water.

[0084] In some embodiments of the present application, the ice-making component 400 is disposed in the refrigerator compartment 210 and / or the freezer compartment 220. An independent storage compartment can be provided for the ice-making component 400, or the ice-making component 400 can share a storage compartment with other items.

[0085] In some embodiments of the present application, the ice-making device further includes a water box 500, and the water box 500 is used to provide the ice-making component 400 with water required for ice making.

[0086] The water box 500 is provided independently of the ice-making part 400. The water box 500 is provided outside the ice-making part 400. The water box 500 and the ice-making part 400 are connected via a water pipe 600. The water in the water box 500 flows into the ice-making part 400 through the water pipe 600 to provide the ice-making part 400 with water required for ice making.

[0087] The water box 500 is used as a water storage carrier for pre-treating water for ice making.

[0088] That is to say, when making ice, the water does not directly enter the ice-making component 400, but first enters the water box 500 and is pre-treated in the water box 500. After the pre-treatment of pressure reduction and temperature reduction, the gas in the water is precipitated, and the pre-treated water then flows into the ice-making component 400 through the water pipeline 600. In this way, the ice-making component 400 uses the water from which the gas has been precipitated in advance to make ice, so that ice cubes without bubbles and with high transparency can be obtained.

[0089] In some embodiments of the present application, refer to Figure 8 The ice-making device includes an ice-making component 400 and a water box 500. The ice-making component 400 is used to make ice, and the water box 500 is used to pre-treat the water for ice-making by reducing pressure and cooling. When making ice, the water first enters the water box 500 and is pre-treated in the water box 500. After the pre-treatment of reducing pressure and cooling, the gas in the water is precipitated, and the pre-treated water flows into the ice-making component 400 through the water pipeline 600. In this way, the ice-making component 400 uses the water from which the gas has been precipitated in advance to make ice, so that ice cubes with no bubbles and high transparency can be obtained.

[0090] In some embodiments of the present application, the ice-making component 400 and the water box 500 are separately and independently arranged, and the two are connected through a water pipeline 600.

[0091] The independent arrangement of the ice-making component 400 and the water box 500 facilitates the flexible arrangement of the installation positions of the ice-making component 400 and the water box 500.

[0092] The independent arrangement of the ice-making component 400 and the water box 500 completely isolates the ice-making space from the water pre-treatment space without affecting each other, thereby ensuring the water pre-treatment effect and the ice-making effect.

[0093] In some embodiments of the present application, Figure 2 In the embodiment, the ice making component 400 and the water box 500 are both arranged in the refrigerating chamber 210 , and the two are arranged in the same room of the refrigerating chamber 210 .

[0094] In some embodiments of the present application, Figure 3 In the embodiment, the ice-making component 400 is disposed in the refrigerating chamber 210, and the water box 500 is disposed on the inner tank 200 of the door body.

[0095] The door body and the box body 100 are rotatably connected via a door hinge, and the water pipeline 600 connected between the ice-making component 400 and the water box 500 is hidden through the door hinge.

[0096] In some embodiments of the present application, refer to Fig. 9 The pre-treatment stage of the water for ice making in the water box 500 includes a decompression treatment stage.

[0097] The decompression treatment stage refers to reducing the gas pressure in the water box 500, thereby reducing the solubility of the gas in the water in the water box 500 and causing the gas in the water to precipitate.

[0098] In some embodiments of the present application, the pretreatment stage of the water for ice making in the water box 500 includes a temperature reduction treatment stage.

[0099] The cooling treatment stage refers to lowering the temperature of the water in the water box 500, thereby reducing the solubility of the gas in the water in the water box 500 and causing the gas in the water to precipitate.

[0100] In some embodiments of the present application, the pretreatment stage of the water for ice making in the water box 500 includes a decompression treatment stage and a temperature reduction treatment stage, and the temperature reduction treatment stage is performed after the decompression treatment stage.

[0101] During the ice-making process of the ice-making component 400, the water box 500 is always in a low-temperature environment to ensure the low temperature of the water and the ice-making effect.

[0107] When water is poured into the water box 500, the water inlet pipe 510 is turned on and the exhaust pipe 520 is turned on. As the water inlet pipe 510 continuously pours water into the water box 500, the water level continuously rises, the distance between the water surface and the cover body 560 gradually decreases, and the air between the water surface and the cover body 560 is discharged through the exhaust pipe 520.

[0108] After the water filling is completed and the water box 500 is evacuated and depressurized, the water inlet pipe 510 is closed and the exhaust pipe 520 continues to be connected. At this time, the water storage chamber is connected to the outside world only through the exhaust pipe 520, and the air in the water storage chamber is discharged through the exhaust pipe 520.
