Description

Technical Field

[0001] This utility model relates to the field of ice-making equipment technology, specifically to an air extraction and filtration component for reducing dissolved air in water. Background Technology

[0002] An ice maker is a refrigeration machine that rapidly produces ice by exchanging heat with water through an evaporator. It mainly consists of components such as a compressor, dryer filter, condenser, expansion valve, evaporator, electrical control box, and check valve. Ice makers are classified according to the shape of the ice produced, including granular ice makers, flake ice makers, square ice makers, round ice makers, tube ice makers, and shell ice makers.

[0003] However, regardless of the shape of the ice cubes produced by the ice maker, the ice cubes contain a large number of tiny air bubbles. To the naked eye, the ice cubes appear as a white mist. This is because when water freezes rapidly, the dissolved gases in the water form bubbles that cannot escape in time and are trapped in the ice cubes, forming tiny cavities. The scattered light then appears as a white mist.

[0004] Currently available ice makers utilize methods to eliminate or reduce air bubbles in ice cubes, including: stirring and agitating water during freezing, ultrasonic vibration, slow directional freezing, circulating laminar water, cutting off portions of the ice cubes containing air bubbles, and pre-boiling.

[0005] Water dissolves gases, so it is necessary to propose a structural device to pre-treat water sources, which can reduce the content of dissolved gases and the amount of dissolved oxygen in the water. After the water is treated in this way, the number of bubbles formed is greatly reduced when the water is quickly frozen into ice. Utility Model Content

[0006] The purpose of this invention is to address the problems of existing ice makers having cumbersome methods for eliminating or reducing air bubbles in ice cubes, high venting costs, and being time-consuming and labor-intensive. We have designed a vacuum filtration component that uses a vacuum pump to extract dissolved gases from the water. Simultaneously, to prevent water from being extracted, a breathable and hydrophobic membrane is added to isolate the water. During vacuuming, gases in the water pass through the breathable and hydrophobic membrane, while the water is blocked. By layering and stacking the breathable and hydrophobic membrane, the extraction area is greatly increased, improving water permeability and achieving the goal of reducing the dissolved gas content in the water. Furthermore, the water source can enter and exit simultaneously, resulting in extremely high extraction efficiency, far surpassing traditional extraction methods, making it practical and convenient.

[0007] The technical solution adopted to solve the above problems is:

[0008] An air extraction filtration assembly for reducing dissolved air in water includes a breathable and hydrophobic membrane, a water flow unit, and an air extraction unit stacked alternately. The water flow unit includes a permeable support layer and a water flow sealing ring that isolates the air extraction port but allows passage through the water inlet and outlet. The air extraction unit includes a permeable support layer and an air extraction sealing ring that isolates the water inlet and outlet but allows passage through the air extraction port. A breathable and hydrophobic membrane is disposed between the water flow sealing ring and the air extraction sealing ring. The breathable and hydrophobic membrane has through-holes facing the water inlet, air extraction port, and water outlet. An air extraction space is formed by the sealed environment created by the upper and lower layers of the breathable and hydrophobic membrane and the inner ring of the air extraction sealing ring. A permeable support layer is disposed within the air extraction space. A water flow space is formed by the sealed environment created by the upper and lower layers of the breathable and hydrophobic membrane and the water flow sealing ring. A permeable support layer is disposed within the water flow space.

[0009] After several sets of water flow units and air extraction units are stacked alternately, all the water inlets on the same side are stacked up and down to form a water inlet chamber, all the water outlets on the same side are stacked up and down to form a water outlet chamber, and all the air extraction ports on the same side are stacked up and down to form an air extraction chamber. Water enters from the water inlet chamber and flows tangentially to the surface of the water flow unit towards the water outlet chamber, while water-soluble gas passes perpendicularly to the surface of the water flow unit through the breathable hydrophobic membrane and is discharged from the air extraction chamber, achieving the filtration effect of gas-liquid separation.

[0010] Furthermore, it also includes a sealing sheet that serves a sealing function, and a housing that connects the water inlet chamber, the water outlet chamber, and the air extraction chamber, wherein the housing is provided with an interface corresponding to each water inlet chamber, the water outlet chamber, and the air extraction chamber.

[0011] Furthermore, the water inlet chamber is connected to the water source to be pumped out, and the water pressure is increased to force the water source into the water inlet chamber. The air extraction chamber is connected to the air extraction device, which extracts the air from the water source to be pumped out through the breathable and hydrophobic membrane, extracting the gas mixed in with the water source to the air extraction space, and then discharges it outward through the air extraction chamber. The pumped water source then flows to the water outlet chamber, which is connected to the ice maker. After cooling and freezing, bubble-free ice blocks are obtained.

[0012] Furthermore, the sealing sheet tightly presses together the multiple layers of alternately stacked and sealed air extraction filter components and seals them with the outer shell. The sealing sheet is provided with connecting holes according to the positions of the water inlet chamber, water outlet chamber and air extraction chamber of the air extraction filter components, including water inlet connecting holes, water outlet connecting holes and air extraction connecting holes. The water inlet connecting holes, water outlet connecting holes and air extraction connecting holes are respectively connected to the interfaces provided with the outer shell, thereby connecting the multiple layers of air extraction filter components in parallel to implement parallel air extraction filtration of the water source.

[0013] Furthermore, the multi-layer sealing sheets and multi-layer air extraction and filtration components are stacked and sealed alternately. Each sealing sheet has a series hole that allows the water outlet chamber of the upper-level air extraction and filtration component to be sealed and connected to the water inlet chamber of the lower-level air extraction and filtration component, and blocks the water inlet chamber of the upper-level air extraction and filtration component. In this way, the multi-layer air extraction and filtration components are connected in series to implement series air extraction and filtration of the water source.

[0014] Furthermore, both the multi-layer sealing sheet and the multi-layer air extraction filter assembly are provided with limit holes or limit grooves on their outer periphery, and are positioned by limit pins or locking bolts.

[0015] Furthermore, the multi-layered alternating water flow units and air extraction units are laid out in a flat plate shape, wound into a spiral shape, or threaded into a cylindrical shape.

[0016] The beneficial effects of this utility model are:

[0017] 1. The air extraction and filtration assembly for reducing dissolved air in water uses a breathable and hydrophobic membrane to isolate water. When vacuuming, gas in the water will pass through the breathable and hydrophobic membrane, while the water is blocked, thus removing gas from the water source.

[0018] 2. By using multiple parallel or series air extraction units, which are laid out and stacked in layers, the air-permeable and hydrophobic membrane can greatly increase the air extraction area in a small space, improve water permeability, and achieve the purpose of reducing the dissolved gas content in the water.

[0019] 3. The water source is readily available and the air extraction efficiency is extremely high, far surpassing traditional air extraction solutions, making it practical and convenient. Attached Figure Description

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and by way of embodiments.

[0028] Example 1 :

[0029] Please see Figures 1 to 4 This embodiment proposes an air extraction filter assembly for reducing dissolved air in water, comprising a multi-layered breathable and hydrophobic membrane 4, a water flow unit 1 and an air extraction unit 2 stacked alternately in a sealed environment, a sealing sheet 7 for sealing, and a housing connecting the water inlet chamber, the water outlet chamber, and the air extraction chamber. The housing has interfaces corresponding to each of the water inlet chamber, the water outlet chamber, and the air extraction chamber. The housing includes an upper cover plate 6 and a base 9, which seal the air extraction filter assembly placed within. The water flow unit 1 includes a permeable support layer 11 and a water flow sealing ring 3 that isolates the air extraction port but allows the water inlet and outlet to flow through. The air extraction unit 2 includes a permeable support layer 11 and an air extraction sealing ring 5 that isolates the water inlet and outlet but allows the air extraction port to flow through. The sealing ring is sealed with a breathable and hydrophobic membrane 4 on its upper and lower surfaces. The air extraction space is formed by the sealed environment of the upper and lower two layers of breathable and hydrophobic membrane 4 and the inner ring of the air extraction sealing ring 5. The permeable support layer 11 is provided in the air extraction space. The water flow space is formed by the sealed environment of the upper and lower two layers of breathable and hydrophobic membrane 4 and the water flow sealing ring 3. The permeable support layer 11 is provided in the water flow space to prevent the upper and lower two layers of breathable and hydrophobic membrane 4 from attracting each other and causing air extraction obstruction.

[0030] The air extraction and filtration assembly has all the water inlets on the same side stacked vertically to form an inlet chamber, all the water outlets on the same side stacked vertically to form an outlet chamber, and all the air extraction ports on the same side stacked vertically to form an air extraction chamber.

[0031] A further implementation scheme is that the water inlet chamber is connected to the water source to be pumped, and the water source is pumped into the water inlet chamber by a pump. The air extraction chamber is connected to the air extraction device, which extracts the air from the water source to be pumped into the water flow unit 1 through a layer of breathable and hydrophobic membrane 4, and extracts the gas mixed in with the water source. The pumped water source then flows into the water outlet chamber. The water outlet chamber is connected to an ice maker, and after cooling and freezing, ice blocks without air bubbles are obtained.

[0032] A further implementation scheme is that the upper and lower sealing sheets 7 and the outer periphery of the air extraction filter assembly are provided with limit grooves and are positioned by locking bolts 8.

[0033] The technical advantage of this embodiment 1 is that by sealing the air extraction and filtration assembly with the outer shell, the water can be isolated by the breathable and hydrophobic membrane 4. When vacuuming, the gas in the water will pass through the breathable and hydrophobic membrane 4, while the water is blocked, thus realizing the extraction of gas from the water source.

[0034] Example 2 :

[0035] See Figure 5This embodiment 2 proposes a parallel single-extraction filtration assembly, including a multi-layer breathable and hydrophobic membrane 4, multiple sets of water flow units 1 and air extraction units 2 stacked alternately in a closed environment, an upper sealing sheet 7 and a lower sealing sheet 7 that play a sealing role, and a shell that connects the water inlet chamber, the water outlet chamber and the air extraction chamber.

[0036] The difference from Embodiment 1 is that: after multiple sets of water flow units 1 and air extraction units 2 are stacked alternately in sequence, all water inlets on the same side are stacked vertically to form a water inlet chamber, all water outlets on the same side are stacked vertically to form a water outlet chamber, and all air extraction ports on the same side are stacked vertically to form an air extraction chamber. The sealing sheet 7 tightly presses the multi-layered alternatingly stacked and sealed air extraction filter assembly and seals it with the outer shell. The sealing sheet 7 is provided with connecting holes according to the positions of the water inlet chamber, water outlet chamber and air extraction chamber of the air extraction filter assembly, including water inlet connecting holes, water outlet connecting holes and air extraction connecting holes. The water inlet connecting holes, water outlet connecting holes and air extraction connecting holes are respectively connected to the interface provided with the outer shell, thereby connecting the multi-layered air extraction filter assembly in parallel to implement parallel air extraction filtration of the water source, thereby increasing the total width of the air extraction filtration.

[0037] The technical advantages of implementing this embodiment 2 are: the water source can enter and exit immediately, and the parallel filtration and air extraction process is extremely efficient, far surpassing the traditional air extraction scheme, and is practical and convenient.

[0038] Example 3 :

[0039] See Figure 6 This embodiment 2 proposes a series multiple air extraction and filtration assembly, including a multi-layer breathable and hydrophobic membrane 4, multiple sets of sealing sheets 7 stacked alternately in a closed environment, a water flow unit 1, an air extraction unit 2, and a shell connecting the water inlet chamber, the water outlet chamber and the air extraction chamber.

[0040] Compared to Embodiment 2, this embodiment differs in that: the multi-layer sealing sheet 7 and the multi-layer air extraction filter assembly are alternately stacked and sealed. Each sealing sheet 7 has a series hole 10 that allows the water outlet chamber of the upper-level air extraction filter assembly to be sealed and connected to the water inlet chamber of the lower-level air extraction filter assembly, and blocks the water inlet chamber of the upper-level air extraction filter assembly. In this way, the multi-layer air extraction filter assembly is connected in series to implement series air extraction filtration of the water source, thereby increasing the total length of the air extraction filtration.

[0041] The technical advantage of implementing this embodiment 3 is that by connecting the water inlet channels in series, the water source is layered to cover the entire air-permeable and hydrophobic membrane 4 of the air extraction and filtration assembly, increasing the total length of the air-permeable and hydrophobic membrane 4 to improve the ability to remove dissolved gases from the water, and facilitating full air extraction, greatly removing gases from the water and significantly reducing the content of dissolved gases in the water.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes, modifications, substitutions and variations can be made without departing from the spirit of the present invention.
