Description

Technical Field

[0001] This utility model relates to the field of refrigeration devices, and in particular to a refrigeration equipment. Background Technology

[0002] In existing refrigeration equipment (such as refrigerators), many products have built-in water circuit integration devices to facilitate users' access to cold water or ice making. These devices introduce an external water source (such as a faucet) into the refrigerator for cooling before supplying it to the distributor or ice maker. Existing water circuit integration devices typically employ a coil-type water box design, where the coiled tubing exchanges heat with the cold air within the refrigeration compartment to cool the water inside the tubing. However, this coil-type water box design has the following technical drawbacks:

[0003] Limited water capacity: Due to its tubular structure, the coil-type water tank has a small internal water capacity, which can usually only meet the cold water needs for a short time. For example, after a user gets a glass of ice water, the cold water in the coil is quickly depleted, and the water that flows out afterward is usually room temperature water, which cannot meet the continuous cold water needs of multiple people in the family.

[0004] Limited heat exchange efficiency: The small water storage capacity of the coil-type water box results in a short residence time of the water in the cooling room, insufficient heat exchange time with the cold air, limited cooling effect, and difficulty in providing a continuous and stable supply of chilled water.

[0005] Complex structure: The pipe connection of the coil-type water box usually requires multiple joints, which increases the risk of water leakage. In addition, the arrangement of multiple coils in a small space is complicated, making production and installation difficult. In particular, if the pipe is dented, the water flow in the pipe will be obstructed, affecting the water output.

[0006] The aforementioned problems render existing coil-type integrated water circuit devices significantly inadequate in meeting users' demands for large quantities of chilled water, improving heat exchange efficiency, and simplifying maintenance. Therefore, there is an urgent need for an integrated water circuit device that can significantly increase water storage capacity, enhance cooling performance, and facilitate easy assembly and disassembly. Summary of the Invention

[0007] To address the problems of limited water storage capacity, restricted heat exchange efficiency, and easily dented water pipes in existing integrated water systems, the purpose of this invention is to provide a refrigeration device that significantly increases water storage capacity, improves cooling effect, and ensures smooth water flow without easily denting water pipes.

[0008] To achieve the above-mentioned utility model objective, one embodiment of this utility model provides a refrigeration device, including a refrigeration chamber and a water circuit integration device, wherein the water circuit integration device is disposed in the refrigeration chamber, and the water circuit integration device includes:

[0009] A water storage box is configured to allow the water inside to exchange heat with the cooling room. The water storage box is provided with a partition, which divides the water storage box into a transfer chamber and a water storage chamber. The transfer chamber (102) is connected to an external water supply end through a water inlet pipe, and the water storage chamber (101) is connected to an external water demand end through a water outlet pipe.

[0010] The filter includes a filter element, an inlet, and an outlet. Liquid flowing into the inlet flows through the filter element to the outlet. The inlet is connected to the transfer chamber, and the outlet is connected to the water storage chamber.

[0011] As a further improvement of this utility model, the volume of the water storage cavity is greater than the volume of the transfer cavity.

[0012] As a further improvement of this utility model, the water storage box has a first water inlet, a first water outlet, a second water inlet, and a second water outlet. The first water inlet is connected to an external water supply end, and the first water outlet is connected to an external water demand end. The transfer cavity is connected to the first water inlet and the second water outlet respectively, and the water storage cavity is connected to the first water outlet and the second water inlet respectively. The first water inlet, the transfer cavity, the second water outlet, the inlet, the outlet, the second water inlet, the water storage cavity, and the first water outlet are sequentially connected.

[0013] As a further improvement of this utility model, a guide part is provided in the water storage cavity, and the guide part guides the water flow from the second water inlet to the first water outlet along a preset path in the water storage cavity.

[0014] As a further improvement of this utility model, the guide portion includes an offset plate that extends away from the first water outlet and guides the water flow to a position away from the first water outlet.

[0015] As a further improvement of this utility model, the water circuit integration device further includes a first water pipe and a second water pipe, wherein the first water pipe is connected to the inlet and the second outlet, and the second water pipe is connected to the outlet and the second inlet.

[0016] As a further improvement of this utility model, the water storage box is disposed at the bottom of the filter, and the second water inlet and the second water outlet are disposed at the top of the water storage box.

[0017] As a further improvement of this utility model, the inlet, the outlet, the first inlet, the first outlet, the second inlet and the second outlet are all provided with quick-connect interfaces for detachable connection with water pipes.

[0018] As a further improvement of this utility model, the water circuit integration device also includes a housing, the water storage box is detachably connected to the housing, and the filter is fixedly connected to the housing.

[0019] As a further improvement of this utility model, the first water inlet is adjacent to the first water outlet, and the second water inlet and the second water outlet are respectively located on both sides of the water storage box.

[0020] Compared with commonly used technologies, this utility model has the following advantages: This refrigeration equipment uses a water storage box instead of a traditional coil-type water box. The water storage box is divided into a transfer chamber and a water storage chamber by a partition. Compared with the limited water storage capacity of existing coil-type water boxes, the water storage box of this invention can store more water, meeting the needs of multiple family members for continuous access to chilled water. Furthermore, the larger area of ​​the water storage box allows for more thorough heat exchange between the stored water and the cold air in the refrigeration room, thus providing cooler water. In addition, the inlet and outlet pipes are simultaneously connected to the water storage box, which then guides the water through the filter. This reduces the complexity of connecting the inlet and outlet pipes and avoids pipe collapse caused by connecting water pipes to multiple parts, thus ensuring smoother water flow. Through the innovative design of the water storage box, this refrigeration equipment overcomes the shortcomings of existing coil-type water boxes, such as insufficient water storage capacity, limited cooling effect, and easy obstruction of water flow, providing users with a more refreshing drinking water experience.

Detailed Implementation

[0029] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0030] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0031] One embodiment of this utility model provides a refrigeration device that significantly increases water storage capacity while improving cooling effect.

[0032] The refrigeration equipment in this embodiment can be a refrigerator, freezer, wine cabinet, ice maker, etc. The following uses a refrigerator as an example to focus on the design and working principle of the water circuit integrated device 100 in the refrigeration chamber of the refrigeration equipment. However, this embodiment is not limited to this and can be applied to other types of refrigeration equipment.

[0033] The refrigerator includes an outer shell, an inner liner, and an insulated cavity. The inner liner forms a cooling compartment for storing food and providing cooling. The cooling compartment can be a refrigerator compartment, a freezer compartment, or a variable temperature compartment. In this embodiment, the cooling compartment is a refrigerator compartment, and the internal temperature is maintained between 0°C and 5°C.

[0034] The water circuit integration device 100 is installed in the refrigeration room to introduce an external water source (such as a faucet) into the refrigerator. After cooling and filtration, the water is supplied to the user for drinking or for ice making. In this embodiment, the water circuit integration device 100 is designed to address the shortcomings of traditional coil-type water boxes by adopting an innovative water storage box 10 structure to achieve a larger water storage capacity, more efficient cooling effect, and higher system reliability.

[0035] like Figure 1-3As shown, the water circuit integration device 100 includes a water storage box 10 and a filter 20; the water storage box 10 is provided with a partition 11, which divides the water storage box 10 into a transfer chamber 102 and a water storage chamber 101. The water storage box 10 is configured to allow the water inside to exchange heat with the cooling room. The transfer chamber 102 is connected to the external water supply end through the water inlet pipe 51, and the water storage chamber 101 is connected to the external water demand end through the water outlet pipe 52.

[0036] Filter 20 includes filter element 21, inlet 22 and outlet 23. Liquid flowing into inlet 22 flows through filter element 21 to outlet 23. Inlet 22 is connected to transfer chamber 102 and outlet 23 is connected to water storage chamber 101.

[0037] The water storage box 10 is configured as a square, injection-molded water jug, replacing the traditional coil-type water jug. The water storage box 10 is made of food-grade polypropylene (PP) material and integrally molded using an injection molding process, ensuring precise dimensions and excellent low-temperature resistance, making it suitable for long-term use in the low-temperature environment of refrigeration rooms. The square design of the water storage box 10 makes full use of the internal space of the refrigeration room. Compared to coil-type water jugs, its dimensions are more regular, and it reduces the wasted space due to coil wall thickness and gaps between coils.

[0038] The partition 11 is an integrally molded partition inside the water storage box 10, which divides the interior of the water storage box 10 into two parts.

[0039] like Figure 3 and 6 As shown, the adapter cavity 102 is located in the corner of the water storage box 10. It is small in size and is mainly used for water circuit connection. The adapter cavity 102 is connected to an external water supply terminal (such as a faucet) to receive external water source and is connected to the inlet 22 of the filter 20 through a pipeline.

[0040] The water storage chamber 101, excluding the transfer chamber 102, occupies most of the volume of the water storage box 10 (approximately 80%-90% of the total volume) and is used for storing and cooling water. The volume of the water storage chamber 101 is significantly larger than that of a traditional coiled water box, capable of storing enough water to meet the continuous chilled water needs of multiple family members. The water storage chamber 101 connects to the outlet 23 of the filter 20 via a connecting hole to receive filtered water and connects to external water-receiving devices (such as distributors or ice makers) via the outlet of the water storage box 10.

[0041] The water storage box 10 is configured to allow heat exchange between the water inside and the cooling chamber. Specifically, the outer surface of the water storage box 10 is exposed to the cold air in the cooling chamber, exchanging heat with the cold air through natural convection and conduction. The square design of the water storage box 10 increases the contact area with the cold air, resulting in higher heat exchange efficiency compared to the linear contact of a coil-type water box. Because the water storage chamber 101 has a larger water storage capacity, the water in the water storage chamber 101 stays in the cooling chamber for a longer time, allowing it to be sufficiently cooled to near the temperature of the cooling chamber, ensuring that users have access to refreshing drinking water.

[0042] Both the inlet pipe 51 and the outlet pipe 52 are connected to the water storage box 10. The transition cavity 102 and the water storage cavity 101 branching off from the water storage box 10 change the direction of the water flow. For example, the water flow can be first introduced from the water storage box 10 into the filter 20 for filtration, and then the filtered water flows back into the water storage box 10. This allows the inlet pipe 51 and the outlet pipe 52 to avoid being connected to different devices separately. (The last sentence appears to be incomplete and possibly refers to a different device.) Figures 1-3 As shown, they can be connected together and then connected to the water storage box 10, which takes up less space, avoids the complex structure of the pipeline, avoids the pipe collapse, and thus makes the water flow more smoothly.

[0043] Filter cartridge 21 uses a combination of activated carbon and ultrafiltration membrane materials, which can effectively remove impurities, odors, and microorganisms from the water, ensuring clean water quality. Filter cartridge 21 is detachably connected to the filter cartridge 21 connector of filter 20 via a rotating plug-in method, facilitating regular replacement. The filtration capacity of filter cartridge 21 is designed to meet household needs, for example, it can treat 500L of water before replacement.

[0044] An external water source enters the inlet 22 of the filter 20 through the transfer chamber 102. After being filtered by the filter element 21, the water flows out from the outlet 23 and enters the water storage chamber 101 for cooling. Finally, it is supplied to the external water demand end through the outlet of the water storage box 10. This water flow path design ensures that the water is filtered before being cooled, avoiding secondary pollution that may occur to the filtered water during the water storage process.

[0045] In one embodiment, the volume of the water storage chamber 101 is greater than the volume of the transfer chamber 102.

[0046] The transfer chamber 102 is located in the corner of the water storage box 10 and has a small volume, about 5 to 15% of the total volume of the water storage box 10. The main function of the transfer chamber 102 is to act as a water transfer hub, receiving external water sources (such as faucets) and directing them to the inlet 22 of the filter 20.

[0047] The water storage chamber 101 occupies most of the volume of the water storage box 10, approximately 85-95% of the total volume, and its capacity far exceeds that of traditional coil water boxes. The water storage chamber 101 is used to store filtered water and is cooled by heat exchange with the cold air in the refrigerator compartment. The water storage chamber 101 can hold enough water to meet the continuous water needs of multiple family members.

[0048] Furthermore, the large-capacity design of the water storage chamber 101 ensures that the water has a longer residence time in the refrigerator (for example, the remaining water can stay for several minutes to several hours after each water extraction), allowing for sufficient heat exchange with the cold air and cooling the water inside to near the refrigerator temperature (2℃-5℃).

[0049] The smaller volume of the transfer chamber 102 is focused on water transfer, ensuring that water flows quickly into the filter 20 for purification, while the larger volume of the water storage chamber 101 is focused on water storage and cooling. This functional zoning design improves the efficiency of the water system, reduces unnecessary space occupation, and maintains water quality.

[0050] Furthermore, this structure facilitates manufacturing. The water storage box 10 is injection molded, and the design of the partition 11 simplifies the manufacturing process of the water storage cavity 101 and the transition cavity 102. The large volume of the water storage cavity 101 and the compact design of the transition cavity 102 are easily realized in the mold design, reducing production costs while ensuring dimensional accuracy, and facilitating production and installation.

[0051] In one embodiment, such as Figure 3 , 6 As shown in Figure 7, the water storage box 10 has a first inlet 12, a first outlet 13, a second inlet 14, and a second outlet 15. The first inlet 12 is connected to an external water supply end, the first outlet 13 is connected to an external water demand end, the transition cavity 102 is connected to the first inlet 12 and the second outlet 15 respectively, and the water storage cavity 101 is connected to the first outlet 13 and the second inlet 14 respectively. The first inlet 12, the transition cavity 102, the second outlet 15, the inlet 22, the outlet 23, the second inlet 14, the water storage cavity 101, and the first outlet 13 are connected sequentially.

[0052] The first water inlet 12 is located on the side wall of the water storage box 10 and is connected to the water inlet pipe 51, which connects to an external water supply (such as a faucet), via a quick-connect interface. The quick-connect interface adopts a quick-plug design to ensure a sealed connection with the water inlet pipe 51. The first water inlet 12 is directly connected to the adapter cavity 102 for receiving external water sources.

[0053] The first water outlet 13 is located on the side wall of the water storage box 10, adjacent to the first water inlet 12, and is connected to the water outlet pipe 52 of an external water demand end (such as a distributor or ice maker) via a quick connector. The first water outlet 13 is connected to the water storage chamber 101, and outputs the cooled water to the water demand end.

[0054] The second water inlet 14 is located at the top of the water storage box 10, near the outlet 23 of the filter 20, and is connected to the outlet 23 of the filter 20 via the second water pipe 42. The second water inlet 14 is connected to the water storage chamber 101 and receives the water purified by the filter 20.

[0055] The second outlet 15 is located at the top of the water storage box 10, near the inlet 22 of the filter 20, and is connected to the inlet 22 of the filter 20 via the first water pipe 41. The second outlet 15 connects to the transfer chamber 102, delivering water from the transfer chamber 102 to the filter 20 for purification. The quick-connect interface of the second outlet 15 is arranged in the same direction as the second inlet 14, optimizing the pipeline connection.

[0056] The water flow path of the water circuit integration device 100 is designed to be unidirectional, flowing from the external water supply end through the water storage box 10 and the filter 20 in sequence, and finally flowing to the external water demand end.

[0057] The water storage box 10 features four inlets and outlets and a unidirectional water flow path, achieving efficient water connection and water quality assurance.

[0058] In one embodiment, such as Figure 3 , 6 As shown in Figures 7 and 8, a guide section 16 is provided inside the water storage cavity 101. The guide section 16 guides the water flow in the water storage cavity 101 along a preset path from the second inlet 14 to the first outlet 13.

[0059] The guide section 16 is a set of flow guiding structures inside the water storage cavity 101. It is integrally formed with the water storage box 10 and uses the same food-grade PP material to ensure low temperature resistance and corrosion resistance. The guide section 16 extends the flow path of water in the water storage cavity 101, enhances the heat exchange effect, and prevents water from short-circuiting (i.e., flowing directly from the second inlet 14 to the first outlet 13).

[0060] The guide section 16 guides the water flow through the water storage chamber 101 for as long a distance as possible, so that the internal water can fully exchange heat with the cooling chamber, and also avoids the formation of resistance due to the long flow path.

[0061] The guide section 16 can form "n" shaped, "Z" shaped or other water flow channels, which prolongs the flow path of water in the water storage chamber 101, while reducing the static deposition of water at the bottom of the water storage chamber 101, reducing the risk of scale and microbial growth, and keeping the water clean.

[0062] In addition, the guide section 16 also allows the water that first flows into the water circuit integration device 100 to flow out first, on the one hand removing stagnant water to avoid internal stagnant water residue, and on the other hand allowing fully cooled water to be discharged first, so that the user gets cooler water.

[0063] In one embodiment, such as Figure 3 , 6 As shown, the guide section 16 includes an offset plate 161 that extends away from the first outlet 13 and guides the water flow to a position away from the first outlet 13.

[0064] The offset plate 161 is a rectangular thin plate, occupying little space and having little impact on the water storage volume. Figure 3 For example, the offset plate 161 extends obliquely from the inner wall of the water storage cavity 101 in a direction away from the first water outlet 13 (i.e., towards the rear wall of the refrigerator compartment). The angle between the plane of the offset plate 161 and the blowing direction of the first water outlet 13 is approximately 30° to 60°.

[0065] After water enters the water storage chamber 101 from the second inlet 14, it flows along the inclined surface of the offset plate 161 to the rear of the water storage chamber 101 (away from the first outlet 13), and then flows forward (closer to the first outlet 13) to the first outlet 13 under the push of the subsequent water flow.

[0066] The offset plate 161 guides the water flow to a rear area away from the first outlet 13, extending the water flow path within the water storage chamber 101 and increasing the heat exchange time between the water and the cold air in the refrigerator compartment. The offset plate 161 prevents water from flowing directly from the second inlet 14 to the first outlet 13, ensuring that the water first reaches the rear of the water storage chamber 101. This fully utilizes the volume and heat exchange area of ​​the water storage chamber 101, improving the uniformity of cooling efficiency. Simultaneously, it reduces the stagnant area of ​​water within the water storage chamber 101, lowering the risk of scale and microbial growth and maintaining long-term water cleanliness.

[0067] like Figure 1 , 3 As shown, the water circuit integration device 100 also includes a first water pipe 41 and a second water pipe 42. The first water pipe 41 is connected to the inlet 22 and the outlet 15, and the second water pipe 42 is connected to the outlet 23 and the inlet 14.

[0068] The first water pipe 41 and the second water pipe 42 are both located in the top space between the water storage box 10 and the filter 20, extending in the same direction along the front side of the refrigerator compartment. The first water pipe 41 and the second water pipe 42 effectively prevent the water pipes from collapsing in the confined space, ensuring smooth water flow and pipe durability.

[0069] like Figure 1 , 3 As shown, the water storage box 10 is located at the bottom of the filter 20, and the second water inlet 14 and the second water outlet 15 are located at the top of the water storage box 10.

[0070] Here, "bottom" can be "below" relative to gravity, and "top" can be "above".

[0071] On the one hand, under the influence of gravity, water tends to flow into the water storage box 10 below. On the other hand, only when there is enough water in the water storage box 10 will it be sent into the filter 20 above, thus ensuring the water capacity in the water storage box 10 and avoiding the problem of water not being available from the outside while there is still residual water inside.

[0072] In one embodiment, the inlet 22, outlet 23, first inlet 12, first outlet 13, second inlet 14 and second outlet 15 are all provided with quick-connect fittings, which are detachably connected to the inlet pipe 51, outlet pipe 52, first water pipe 41 and second water pipe 42, respectively.

[0073] The quick-connect fittings are made of food-grade materials, are low-temperature resistant, and impact-resistant. Each quick-connect fitting includes a connector, a sealing ring, and a snap-fit ​​structure. The outer diameter of the quick-connect fitting matches the inner diameter of the water pipe. The sealing ring is made of silicone to ensure a tight seal and prevent the water pipe from falling off after locking.

[0074] The quick-connect interface allows users to easily insert and remove the water hose. The snap-lock design of the quick-connect interface ensures that the water hose automatically locks after insertion, and the water hose can be released by pressing the snap-lock. The operation is simple, making it convenient for users to disassemble, clean, and install, and also makes it easy to replace the filter cartridge 21.

[0075] like Figure 1 , 3 As shown in Figures 4 and 5, the water circuit integrated device 100 also includes a housing 30, a water storage box 10 which is detachably connected to the housing 30, and a filter 20 which is fixedly connected to the housing 30.

[0076] The water storage box 10 is equipped with a buckle, and the box body 30 is equipped with a slot. The connection is achieved through the snap-fit, which makes it easy for users to install or remove the filter element 21 or the water storage box 10. The box body 30 is fixed to the left side wall of the inner liner of the refrigerator by screws. The fixing point is located on the back of the box body 30 to ensure stable installation.

[0077] In particular, combined with the aforementioned quick-connect fittings, multiple parts of the water circuit integration device 100 can be easily disassembled and assembled, achieving the advantage of convenient maintenance.

[0078] like Figure 6 , 7 As shown, the first inlet 12 is adjacent to the first outlet 13, and the second inlet 14 and the second outlet 15 are located on both sides of the water storage box 10.

[0079] The first inlet 12 and the first outlet 13 are arranged horizontally along the side wall of the water storage box 10, which facilitates the connection of external pipelines to the first inlet 12 and the first outlet 13 at the same position. The adjacent layout reduces the routing length of the inlet pipe 51 and the outlet pipe 52, optimizes the spatial arrangement of external pipelines, and avoids a messy pipeline layout.

[0080] The arrangement of the second inlet 14 and the second outlet 15 on both sides facilitates the same-direction connection of the first water pipe 41 and the second water pipe 42, reducing pipe crossings.

[0081] This layout simplifies the pipework arrangement, enhances the ease of disassembly and assembly and spatial adaptability, reduces pipe interference, adapts to the needs of ultra-thin refrigerators, and improves the practicality of the water circuit integration device 100.

[0082] Compared with the prior art, this embodiment has the following beneficial effects:

[0083] This refrigeration equipment uses a water storage box 10 instead of a traditional coil-type water box. The water storage box 10 is internally divided into a transfer chamber 102 and a water storage chamber 101 by a partition 11. Compared to the limited water capacity of existing coil-type water boxes, the water storage box 10 of this invention can store more water, meeting the needs of multiple family members for continuous access to chilled water. Furthermore, the larger surface area of ​​the water storage box 10 allows for more thorough heat exchange between the stored water and the cold air in the refrigeration room, thus providing cooler water. In addition, both the inlet and outlet pipes are connected to the water storage box, which then directs the water to the filter for purification. This reduces the complexity of the inlet and outlet pipe connections and avoids pipe collapse caused by connecting water pipes to multiple parts, thus ensuring smoother water flow. Through the innovative design of the water storage box 10, this refrigeration equipment overcomes the shortcomings of existing coil-type water boxes, such as insufficient water storage, limited cooling effect, and easy obstruction of water flow, providing users with a more refreshing drinking water experience.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0085] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
