Description

Technical Field

[0001] This utility model relates to the field of ice-making equipment technology, and more specifically, to a waterproof and breathable module and an ice-making device. Background Technology

[0002] Ice-making devices are a practical function in modern refrigerators. The general principle is that water is pumped into the evaporator surface and cooled to its freezing point by a low-temperature refrigerant. Unfrozen water flows back to the storage tank for circulation. When the ice layer reaches a set thickness, hot air from the compressor enters the evaporator jacket, melting the thin film between the ice layer and the evaporator. The ice blocks then fall into the ice storage tank due to gravity for the user to use. The inventors discovered that in some existing ice-making devices, due to water quality or transportation issues, the water used for ice making often contains gases. This results in air bubbles or voids forming in the ice blocks after freezing, leading to opaque, unattractive ice, a loose structure that is easily broken, and ultimately affecting the quality of the ice.

[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] The following describes in detail, with reference to the accompanying drawings, the specific structure of a waterproof and breathable module provided by this utility model and the corresponding technical effects it brings.

[0037] Please refer to Figures 1-5 The present invention provides a waterproof and breathable module 1. First, it should be noted that the waterproof and breathable module 1 is installed in the ice-making device. Through its treatment of water, it eliminates the gas contained in the water, thereby ensuring that when the water is used to make ice, the formation of air bubbles in the ice cubes is avoided, thus improving the quality and appearance of the ice cubes.

[0038] Such as combination Figure 1 and Figure 3 As shown, the waterproof and breathable module 1 includes a first housing 100 and a second housing 200 that overlap each other. The first housing 100 and the second housing 200 are detachably connected and together define an installation chamber. A waterproof and breathable component is installed in the installation chamber, which divides the installation chamber into a first chamber 400 and a second chamber 500. The waterproof and breathable component includes a support plate 310 and a waterproof and breathable membrane 320. The waterproof and breathable membrane 320 is fixedly covered on the side of the support plate 310 near the first chamber 400. The support plate 310 has a vent 311. The first housing 100 has an air extraction port 240 that communicates with the second chamber 500. The second housing 200 has a water inlet 140 and a water outlet 150 that communicate with the first chamber 400. The waterproof and breathable membrane 320 is used to restrict the liquid in the first chamber 400 from entering the second chamber 500.

[0039] Understandably, the aforementioned air extraction port 240 is used to connect to an external vacuum generator, the water inlet 140 can be connected to an external water source, and the water outlet 150 can be connected to a water storage tank. That is, an external water source can inject water into the first chamber 400 through the water inlet 140, and under the action of the water pump, the water in the first chamber 400 is drawn out from the water outlet 150 to form a flowing water path.

[0040] It should be noted that, please refer to Figure 3 When the waterproof and breathable module 1 is in the upright position, the first housing 100 is the upper housing and the second housing 200 is the lower housing. When there is water in the first chamber 400, the waterproof and breathable membrane 320 is used to restrict the water in the first chamber 400 from entering the second chamber 500 and to filter the air in the water into the second chamber 500.

[0041] Alternatively, the waterproof and breathable membrane 320 is typically an ePTFE membrane, which can be made of polytetrafluoroethylene, polyurethane, polyester, or polypropylene.

[0042] Therefore, after the external water source injects water into the first chamber 400 through the water inlet 140, the vacuum generator is activated, thereby generating negative pressure in the first chamber 400. Due to the presence of the waterproof and breathable membrane 320, the water in the first chamber 400 is blocked by the waterproof and breathable membrane 320 and will not flow into the second chamber 500. The gas in the water in the first chamber 400 will enter the second chamber 500 through the waterproof and breathable membrane 320 and the vent 311 of the support plate 310, thereby removing air bubbles in the water in the first chamber 400. This improves the quality of the ice produced by the ice-making device when the water is used for ice making.

[0043] It should be noted that since the waterproof and breathable membrane 320 covers the support plate 310, the support plate 310 can support the waterproof and breathable membrane 320, thereby reducing the deformation or damage of the waterproof and breathable membrane under negative pressure and water gravity, and improving the service life of the waterproof and breathable membrane.

[0044] Optionally, in order to ensure the connection strength between the waterproof and breathable membrane and the support plate 310, the waterproof and breathable membrane 320 can be glued, ultrasonically welded or integrally injection molded onto the surface of the support plate 310 to ensure that the waterproof and breathable membrane 320 is fixed to the surface of the support plate 310 and improve the structural stability of the waterproof and breathable module 1.

[0045] Optionally, in order to ensure the airtightness of the waterproof and breathable membrane 320, a sealant is applied to the outer periphery of the waterproof and breathable membrane 320, and a sealing ring is also provided on the outer periphery of the waterproof and breathable membrane 320 to prevent liquid in the first chamber 400 from entering the second chamber 500 and causing water leakage.

[0046] Combination Figure 4 In this embodiment, the first housing 100 includes a first enclosure plate 120 and a first end plate 110. The first enclosure plate 120 surrounds the first end plate 110. The first end plate 110 is also provided with a water-pressing block 130. The water-pressing block 130 is opposite to and spaced apart from the waterproof and breathable membrane 320. It can be understood that the water-pressing block 130 can compress the space of the first chamber 400, so that the water flowing through the first chamber 400 can come into more full contact with the waterproof and breathable membrane 320, reducing useless space and enhancing the degassing efficiency of the water in the first chamber 400.

[0047] Furthermore, the outer peripheral wall of the water-pressing block 130 is provided with a plurality of spaced-apart rib baffles 131. The plurality of rib baffles 131 are arranged circumferentially along the outer peripheral wall of the water-pressing block 130. The end of the rib baffle 131 away from the first end plate 110 is spaced apart from the waterproof and breathable membrane 320, and the side of the rib baffle 131 away from the water-pressing block 130 is spaced apart from the first enclosure plate 120. In addition, the rib baffles 131 are also spaced apart from each other. Thus, the water flow in the first chamber 400 can be relatively uniformly circulated to the surrounding area through the rib baffles 131. When the negative pressure generator is connected to the air extraction port 240 to extract air from the first chamber 400, the water in the first chamber 400 is degassed more fully.

[0048] Optionally, the distance between the pressure block 130 and the waterproof and breathable membrane 320 is between 1.5 and 3 mm. This slows down the water flow rate in the first chamber 400. For example, the distance between the pressure block 130 and the waterproof and breathable membrane 320 can be 1.5 mm, 1.6 mm, 1.8 mm, 2 mm, 2.2 mm, 2.5 mm, or 2.8 mm.

[0049] Combination Figure 5 In this embodiment, the second housing 200 includes a second enclosure plate 220 and a second end plate 210. The second enclosure plate 220 surrounds the second end plate 210 and is opposite to the first enclosure plate 120. The first end plate 110 is opposite to the second end plate 210. A ring-shaped support platform 230 is protruding inside the second enclosure plate 220. The support platform 230 is used to support the support plate 310. The support plate 310 is opposite to the second end plate 210. The waterproof and breathable membrane 320, the first enclosure plate 120, the second enclosure plate 220 and the first end plate 110 together define the first chamber 400. The support plate 310, the waterproof and breathable membrane 320, the second enclosure plate 220 and the second end plate 210 together define the second chamber 500.

[0050] Understandably, the ring-shaped support platform 230 can provide support for the support plate 310.

[0051] In detail, an annular groove 231 is provided on the side of the support platform 230 away from the first enclosure plate 120. The groove 231 forms a first step surface 232 and a second step surface 233 on the support platform 230. The second step surface 233 is the end face of the groove 231. The support plate 310 is installed on the groove 231 and abuts against the second step surface 233. That is to say, by setting the groove 231, the support plate 310 can be stably installed on the support platform 230, so as to prevent the support plate 310 with integrated waterproof and breathable membrane 320 from easily shaking when water is introduced into the first chamber 400, thereby improving the structural stability.

[0052] Optionally, when the sealant is applied to the outer periphery of the waterproof and breathable membrane 320, it can also be applied between the support plate 310 and the first step surface 232. That is, the sealant can overflow onto the inner periphery of the tank 231 to ensure that water in the first chamber 400 does not enter the second chamber 500 through the gaps in the tank 231.

[0053] Optionally, the sealing ring can also be located between the outer periphery of the waterproof and breathable membrane 320 and the inner peripheral sidewall of the tank 231. That is, the sealing ring can simultaneously abut against the outer periphery of the waterproof and breathable membrane 320, the outer periphery of the support plate 310, and the inner peripheral sidewall of the tank 231 to ensure that water in the first chamber 400 does not enter the second chamber 500 through the gaps in the tank 231.

[0054] Understandably, a sealing ring can be pre-set on the outer periphery of the waterproof and breathable membrane 320, and then sealant can be applied to the waterproof and breathable membrane 320.

[0055] Optionally, to prevent the support plate 310 from deforming under negative pressure, a support portion 312 is provided on the side of the support plate 310 near the second chamber 500. The support portion 312 abuts against the end wall of the second chamber 500. That is, the support portion 312 protrudes from the support plate 310 to form a sheet (for example, in this embodiment, two parallel sheet-shaped support portions 312 are provided) and abuts against the second end plate 210. When the air extraction port 240 is connected to the vacuum generator and the vacuum generator is started, the abutment between the support portion 312 and the second end plate 210 can support the support plate 310, thereby improving the strength of the support plate 310.

[0056] In addition, the support 312 is provided with a number of openings 313. With this arrangement, the air filtered by the waterproof and breathable membrane 320 located on the outer periphery can also be drawn to the outside through the openings to ensure filtration efficiency. In detail, the openings 313 in this embodiment are roughly semi-circular. Of course, in some other embodiments, the shape of the openings 313 can also be other shapes, such as round holes, elliptical holes or other shapes. The shape of the openings 313 is not specifically limited here.

[0057] In detail, in this embodiment, there are multiple vent holes 311, which are evenly spaced on the support plate 310. The vent holes 311 are used for air to pass through and be extracted, and at the same time, the even spacing ensures the uniformity of water degassing in the first chamber 400.

[0058] In order to improve the efficiency of assembling the first housing 100 and the second housing 200, in some embodiments, a first mating part 121 is provided on the inner side of the first enclosure 120. When the first housing 100 and the second housing 200 are engaged, the first mating part 121 abuts against the inner wall of the second enclosure 220. It can be understood that the first mating part 121 can play a positioning role in the assembly of the first housing 100 and the second housing 200, thereby improving the assembly efficiency of the first housing 100 and the second housing 200.

[0059] It should be noted that the distance between the end of the first mating part 121 away from the first end plate 110 and the first end plate 110 is the first distance, and the distance between the end of the first surrounding plate 120 away from the first end plate 110 and the first end plate 110 is the second distance, with the first distance being greater than the second distance. Therefore, it can be understood that the protruding height of the first mating part 121 is greater than the protruding height of the first surrounding plate 120, forming a snap-fit ​​shape with the second surrounding plate 220, facilitating the assembly of this module.

[0060] Of course, in some other embodiments, a second mating part is provided on the inner side of the second enclosure 220. When the first housing 100 and the second housing 200 are mated, the second mating part abuts against the inner wall of the first enclosure 120. Similarly, the second mating part can play a positioning role in the assembly of the first housing 100 and the second housing 200, thereby improving the assembly efficiency of the first housing 100 and the second housing 200.

[0061] In this embodiment, the first housing 100 and the second housing 200 are connected by threaded fasteners, which ensures the connection strength between the first housing 100 and the second housing 200 and also facilitates disassembly and assembly by operators.

[0062] It should be noted that, in this embodiment, both the inlet 140 and the outlet 150 are disposed on the first end plate 110, and the inlet 140 and the outlet 150 are spaced apart along the length of the first end plate 110. Optionally, in some embodiments, in order to ensure that the water in the first chamber 400 is not drawn out of the outlet 150 too quickly, the distance between the inlet 140 and the outlet 150 is greater than half the length of the first end plate 110. The air extraction port 240 is disposed on the second end plate 210.

[0063] This utility model embodiment also provides an ice-making device, including the above-mentioned waterproof and breathable module 1.

[0064] In summary, this utility model embodiment provides a waterproof and breathable module 1 and an ice-making device. The ice-making device includes a waterproof and breathable module 1, which includes a first housing 100 and a second housing 200 that overlap each other. The first housing 100 and the second housing 200 are detachably connected and together define an installation chamber. A waterproof and breathable component is installed in the installation chamber, which divides the installation chamber into a first chamber 400 and a second chamber 500. The waterproof and breathable component includes a support plate 310 and a waterproof and breathable membrane 320. The waterproof and breathable membrane 320 is fixedly covered on the side of the support plate 310 near the first chamber 400. The support plate 310 has a vent 311. The first housing 100 has an air extraction port 240 communicating with the second chamber 500. The second housing 200 has a water inlet 140 and a water outlet 150 communicating with the first chamber 400. The waterproof and breathable membrane 320 is used to restrict the liquid in the first chamber 400 from entering the second chamber 500. When the external vacuum generator is connected to the air extraction port 240 and started, the gas in the water in the first chamber 400 will enter the second chamber 500 through the waterproof and breathable membrane 320 and the air vents 311 of the support plate 310, thereby removing air bubbles in the water in the first chamber 400 and improving the quality of the ice produced by the ice-making device when the water is used for ice making.

[0065] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
