Description

Technical Field

[0001] This utility model relates to the technical field of ice-making water dispensers, and in particular to water circuit systems and ice-making water dispensers. Background Technology

[0002] In related technologies, the water circuit system of ice-making water dispensers involves multiple functions such as hot water, cold water, and ice-making water replenishment. Each function's corresponding water circuit requires separate control of its start and stop. For example, hot water requires a hot water pump to provide the power to dispense water, and the hot water outlet requires a hot water outlet valve to open and close the hot water function; cold water requires a cold water pump to provide the power to dispense water, and the outlet requires a cold water outlet valve to open and close the cold water function; ice-making water replenishment requires a separate ice pump to draw water from the cold water zone to the ice container.

[0003] Therefore, the entire water system requires multiple sets of pumps and valves to achieve its functions, resulting in a large electrical load and high implementation costs. At the same time, multiple pumps and valves correspond to multiple water interfaces, making the production and assembly process complex and increasing the risk of leakage and failure. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in related technologies. To this end, this utility model proposes a water system that helps reduce the number of water pumps, thereby significantly reducing costs, and also reducing production assembly difficulty and quality risks.

[0005] This utility model also proposes an ice-making water dispenser.

[0006] The water system according to a first aspect embodiment of the present invention includes:

[0007] The first water channel structure includes a normal temperature water zone, a water outlet valve, and a first water outlet, wherein the normal temperature water zone is connected to the first water outlet through the water outlet valve;

[0008] The second water channel structure includes a cold water zone, a cold water pump, and a second outlet, wherein the cold water zone and the inlet of the cold water pump are connected.

[0009] The third water channel structure includes an ice-making box;

[0010] The switching valve has a first switching state and a second switching state. In the first switching state, the cold water pump is connected to the second water outlet through the switching valve; in the second switching state, the cold water pump is connected to the ice maker through the switching valve.

[0011] According to the water system of this utility model embodiment, by incorporating a cold water pump, the usage time for cold water extraction and ice making can be staggered as needed. This allows water to be pumped from the cold water zone during both cold water extraction and ice making, enabling two water circuits to share a single cold water pump. The cold water pump is used for both cold water extraction and ice making, and is coordinated with a switching valve. When a user extracts water, the cold water pump is activated, and the normally closed water circuit of the switching valve is opened, allowing cold water to be extracted. During ice making, the normally closed water circuit of the switching valve is closed, and cold water enters the ice-making box from the normally open water circuit of the switching valve to meet the ice-making water replenishment requirements. When a user needs to extract water during ice-making water replenishment, the user's cold water demand is prioritized. Therefore, by adopting the above structure, the design of the water system is optimized, the number of water pumps is reduced, the cold water pump is fully utilized, and the utilization rate is improved. This significantly reduces costs while also greatly reducing production assembly difficulty and quality risks.

[0012] According to one embodiment of the present invention, the ambient temperature water zone is connected to the cold water zone so as to replenish water to the cold water zone through the ambient temperature water zone.

[0013] According to one embodiment of the present invention, a separation structure is provided between the room temperature water zone and the cold water zone, and the room temperature water zone overflows to the cold water zone through the top of the separation structure.

[0014] According to one embodiment of the present invention, the partition structure is provided with an overflow groove, which is connected to the ambient temperature water zone and the cold water zone respectively.

[0015] According to one embodiment of the present invention, the cold water zone is provided with a cold water full water level line, and the height of the cold water full water level line is lower than the bottom surface of the normal temperature water zone.

[0016] According to one embodiment of the present invention, a first liquid level switch is provided in the room temperature water zone.

[0017] According to one embodiment of the present invention, a second liquid level switch is provided in the cold water zone.

[0018] According to one embodiment of the present invention, the first water circuit structure further includes a hot water tank, the inlet of which is connected to the ambient temperature water zone, and the outlet of which is connected to the outlet valve.

[0019] According to one embodiment of the present invention, the bottom of the ambient temperature water zone is connected to the water inlet of the hot water tank, and the water inlet of the hot water tank is positioned lower than the water outlet of the hot water tank.

[0020] According to one embodiment of the present invention, the hot tank is provided with a steam output end for discharging steam, and a condensation tank is provided on one side of the ambient temperature water zone, and the steam output end is connected to the condensation tank.

[0021] The ice-making water dispenser according to a second aspect of the present invention includes the water system described in the first aspect of the present invention.

[0033] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0034] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0036] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0038] In related technologies, firstly, in addition to the diaphragm pump 810 that draws water from the water tank 820, the entire system of the ice-making water dispenser also requires three water pumps (hot water pump, cold water pump 220, and ice pump) to realize its function. The cost of realizing the function is high. At the same time, there are many electrical and water interfaces with similar functions, which can easily lead to problems such as incorrect terminal insertion and water leakage in the pipes.

[0039] Secondly, the actual utilization rate of the three water pumps is very low. The hot water pump and the cold water pump 220 only work when the user draws water. For example, if the whole machine produces 4L of hot water in 1 hour, the hot water pump can empty the water in less than 3 minutes; if the whole machine produces 3L of cold water in 1 hour, the cold water pump 220 can also empty the cold water in less than 3 minutes, with a utilization rate of less than 5%; the ice pump is also only used when the whole machine is in ice-making mode, and its utilization rate is far less than 50%.

[0040] Meanwhile, the three pumps, each with its own function, have different flow rate requirements. For example, hot water needs to be at least 1.2L / min to ensure a good user experience, while the flow rate needs to be less than 2L / min to avoid the hot water temperature being too low due to excessive flow. Similarly, the ice pump and the cold water pump 220 also have corresponding flow control requirements. This results in various contradictory and differentiated requirements for the core material pumps, which in turn affects the implementation cost and effectiveness of the technical solution.

[0041] The following is combined Figures 1-5 The ice-making water circuit system and ice-making water dispenser according to embodiments of the present invention will be described. It will be understood that, in embodiments of the present invention, the ice-making water dispenser includes the aforementioned water circuit system.

[0042] Understandably, referring to Figure 1 and Figure 2In this embodiment of the invention, the ice-making water circuit system includes a first water circuit structure, a second water circuit structure, a third water circuit structure, and a switching valve 400. The first water circuit structure includes a room temperature water zone 110, a water outlet valve 120, and a first water outlet for outputting liquid from the room temperature water zone 110. The room temperature water zone 110 is connected to the first water outlet through the water outlet valve 120. The second water circuit structure includes a cold water zone 210, a cold water pump 220, and a second water outlet for outputting liquid from the cold water zone 210. The cold water zone 210 and the inlet of the cold water pump 220 are connected. The third water circuit structure includes an ice-making box 310. The switching valve 400 has a first switching state and a second switching state. In the first switching state, the cold water pump 220 is connected to the second water outlet through the switching valve 400. In the second switching state, the cold water pump 220 is connected to the ice-making box 310 through the switching valve 400.

[0043] It should be noted that, in this embodiment, the switching valve 400 has a normally closed water path and a normally open water path. The normally closed water path is connected to the second outlet and the cold water pump 220, and the normally open water path is connected to the cold water pump 220 and the ice maker 310. Therefore, in the first switching state, the normally closed water path of the switching valve 400 is open and the normally open water path is closed, and cold water is discharged through the second outlet. In the second switching state, the normally closed water path of the switching valve 400 is closed and the normally open water path is open, and cold water enters the ice maker 310 from the normally open water path of the switching valve 400.

[0044] According to the water system of this utility model embodiment, by providing a cold water pump 220, the usage time of cold water extraction and ice making can be staggered as needed. This allows water to be pumped out of the cold water zone 210 during both cold water extraction and ice making, enabling two water circuits to share a single cold water pump 220. The cold water pump 220 is used for both cold water extraction and ice making, and in conjunction with a switching valve 400, when the user extracts water, the cold water pump 220 is turned on, and the normally closed water circuit of the switching valve 400 is opened, allowing cold water to be extracted. During ice making, the normally closed water circuit of the switching valve 400 is closed, and cold water enters the ice-making box 310 from the normally open water circuit of the switching valve 400 to meet the ice-making water replenishment requirements. When the user needs to extract water during the ice-making water replenishment process, the user's cold water demand is prioritized. Therefore, by adopting the above structure, the design of the water system is optimized, the number of water pumps is reduced, the cold water pump 220 is fully utilized, the utilization rate is improved, and costs are significantly reduced while production assembly difficulty and quality risks are also significantly reduced.

[0045] It should be noted that, in this embodiment of the present invention, the switching valve 400 can be configured as a solenoid directional valve, a pneumatic directional valve, or an electric directional valve, etc., and is not limited thereto. It can be understood that the switching valve 400 is a three-way directional valve.

[0046] Specifically, refer to Figures 1 to 5In this embodiment of the invention, the ambient temperature water zone 110 is connected to the cold water zone 210 so that water can be supplied to the cold water zone 210 through the ambient temperature water zone 110. Since the water supply to the cold water zone 210 is achieved through the ambient temperature water zone 110, the water supply pipelines for both the ambient temperature water zone 110 and the cold water zone 210 are the same, resulting in less material usage, lower cost, and a simpler manufacturing process.

[0047] Specifically, refer to Figure 1 and Figure 2 In this embodiment of the present invention, the first water circuit structure further includes a diaphragm pump 810. The inlet of the diaphragm pump 810 is connected to a water supply source, and the outlet of the diaphragm pump 810 is connected to the ambient temperature water zone 110. With the above structure, it can be understood that in some embodiments of the present invention, the water supply source can be a water tank 820, and the diaphragm pump 810 draws water from the water tank 820 and replenishes it to the ambient temperature water zone 110.

[0048] Of course, in some other embodiments of this utility model, the water supply source can also be connected to an external tap water source, which is not limited here.

[0049] Understandably, referring to Figure 1 and Figure 2 In this embodiment of the utility model, the ambient temperature water zone 110 and the cold water zone 210 are arranged adjacent to each other, making it easier and faster to replenish the cold water zone 210, improving the replenishment efficiency, and the spatial layout is reasonable and saves space.

[0050] Specifically, refer to Figures 1 to 5 In this embodiment of the invention, a separation structure 500 is provided between the ambient temperature water zone 110 and the cold water zone 210. The ambient temperature water zone 110 overflows into the cold water zone 210 through the top of the separation structure 500. Using this structure, the separation structure 500 separates the ambient temperature water zone 110 and the cold water zone 210, providing physical isolation and ensuring that the ambient temperature water and cold water do not mix directly. When the ambient temperature water zone 110 is full, it overflows into the cold water zone 210 through the top of the separation structure 500, thus replenishing the cold water zone 210. This overflow replenishment method is simple in structure and helps reduce material usage.

[0051] Specifically, refer to Figures 1 to 5 In this embodiment of the invention, the partition structure 500 is provided with an overflow groove 510, which is connected to the ambient temperature water zone 110 and the cold water zone 210 respectively. With this structure, the overflow groove 510 allows water to flow into the cold water zone 210 after the ambient temperature water zone 110 is full, thus replenishing the cold water zone 210. By directly cutting or grooving the partition structure 500 to form the overflow groove 510 and connecting it to the ambient temperature water zone 110 and the cold water zone 210, no additional pipe connections or complex components are required, thus simplifying the structural design and manufacturing process.

[0052] Specifically, in this embodiment of the present invention, the cold water zone 210 is provided with a cold water full water level line, the height of which is lower than the bottom surface of the normal temperature water zone 110.

[0053] This can be understood as referring to Figures 1 to 5 The aforementioned ambient temperature water zone 110 is located above the cold water zone 210. One side wall of the partition structure 500 faces the ambient temperature water zone 110, while the opposite side wall faces the cold water zone 210. This design ensures that the bottom of the ambient temperature water zone 110 is higher than the top of the full water level line of the cold water zone 210, creating a height difference between them. This conforms to the principle that hot air rises and cold air descends, preventing temperature fluctuations between the ambient temperature and cold water zones. Furthermore, the height difference controls the inlet and outlet water rates. Additionally, the ambient temperature water zone 110 and the cold water zone 210 can share the partition structure 500, reducing material and manufacturing costs and simplifying the manufacturing process.

[0054] Of course, in some embodiments, the above-mentioned room temperature water zone 110 can also be replenished to the cold water zone 210 by means of siphon, water pump or other means.

[0055] Understandably, referring to Figures 1 to 5 In this embodiment of the utility model, a first liquid level switch 610 is provided in the room temperature water zone 110, and a second liquid level switch 620 is provided in the cold water zone 210.

[0056] With the above structure, the ambient temperature water zone 110 is equipped with a first liquid level switch 610, and the cold water zone 210 is equipped with a second liquid level switch 620. As long as either the first liquid level switch 610 or the second liquid level switch 620 detects a water shortage signal, the whole machine will start the diaphragm pump 810 to replenish water. The water replenishment of the cold water zone 210 is achieved by overflowing when the ambient temperature water zone 110 is full, so as to always ensure the water level of the ambient temperature water zone 110. Prioritize the water volume and flow rate of the hot water pump, so that the input and output of hot water are at a stable level, avoiding the problem of abnormal hot water caused by untimely water replenishment or simultaneous use of multiple functions.

[0057] Specifically, in this embodiment of the present invention, both the first liquid level switch 610 and the second liquid level switch 620 are float-type liquid level switches.

[0058] Understandably, referring to Figures 1 to 4 Float-type level switches provide intuitive liquid level monitoring. They detect the liquid level by having a float in contact with the liquid. The float moves up and down as the liquid level changes, thus providing a clear indication of the liquid level. Float-type level switches typically have a mechanical structure that can accurately trigger the switch to control the liquid level. They are not only simple in structure but also easy to install and maintain.

[0059] Of course, in some embodiments, the first liquid level switch 610 and the second liquid level switch 620 may both be capacitive liquid level switches, optical liquid level switches, etc., which are not limited here.

[0060] Understandably, referring to Figure 1 In this embodiment of the invention, the first water circuit component further includes a hot water tank 700, the inlet of which is connected to the ambient temperature water zone 110, and the outlet of which is connected to the outlet valve 120. With the above structure and arrangement, the inlet of the hot water tank 700 is connected to the ambient temperature water zone 110 to provide hot water to the user.

[0061] Specifically, refer to Figure 1 In this embodiment of the utility model, the bottom of the room temperature water zone 110 is connected to the water inlet of the hot tank 700, and the position of the water inlet of the hot tank 700 is lower than the position of the water outlet of the hot tank 700.

[0062] The above structure facilitates control of the inlet and outlet water rates of the hot water tank 700. For example, when the water level in the hot water tank 700 drops, the water level difference between the hot water tank 700 and the ambient temperature water zone 110 increases. Due to the increased water level difference, water in the ambient temperature water zone 110 is forced into the hot water tank 700, increasing the inlet water rate. This inlet water process continues until the water level in the hot water tank 700 rises, the water level difference decreases, and the inlet water rate decreases accordingly. When the water level in the hot water tank 700 rises, the water level difference between the outlet end of the hot water tank 700 and the first outlet decreases. The outlet valve 120 adjusts its opening based on the water level difference at the outlet end of the hot water tank 700. When the water level in the hot water tank 700 is high, the opening of the outlet valve 120 increases, increasing the outflow rate of the water in the hot water tank 700. As hot water flows out, the water level in the hot water tank 700 gradually drops, the water level difference increases, and the opening of the outlet valve 120 decreases accordingly, reducing the outflow rate.

[0063] Understandably, referring to Figure 4 and Figure 5 In this embodiment of the utility model, the hot tank 700 is provided with a steam output end for discharging steam, and a condensation tank 111 is provided on one side of the room temperature water zone 110, with the steam output end connected to the condensation tank 111.

[0064] With the above structure, the steam generated by the hot tank 700 flows back to the condenser tank 111. After the steam in the condenser tank 111 is condensed, the excess condensate overflows to the ambient temperature water zone 110, which enriches the function, improves the practicality, and enables water recycling, thus saving resources.

[0065] Specifically, refer to Figure 4 and Figure 5In this embodiment of the invention, an overflow channel 1111 is provided on one side wall of the condensation tank 111. The overflow channel 1111 is connected to the ambient temperature water zone 110. With the above arrangement, the existence of the overflow channel 1111 creates liquid communication between the condensation tank 111 and the ambient temperature water zone 110. When the liquid level in the condensation tank 111 is too high, the excess condensate will flow into the ambient temperature water zone 110 through the overflow channel 1111, thereby achieving liquid level regulation and balance.

[0066] Specifically, refer to Figure 4 and Figure 5 In this embodiment of the invention, one end of the overflow channel 1111 is connected to one side wall of the ambient temperature water zone 110, and the bottom wall of the overflow channel 1111 is lower than the upper edge of the other side walls of the condensation tank 111. With this structure, since the bottom wall of the overflow channel 1111 is lower than the upper edge of the other side walls of the condensation tank 111, the overflow direction is defined. Condensate can flow along the overflow channel 1111 to the ambient temperature water zone 110, guiding the condensate into the ambient temperature water zone 110. This effectively removes condensate and prevents it from stagnating in the condensation tank 111, thus improving structural stability.

[0067] Specifically, refer to Figure 4 and Figure 5 In this embodiment of the invention, the sidewall of the room temperature water zone 110 is provided with a flow guiding structure 112, which is connected to the overflow channel 1111 to guide the liquid into the room temperature water zone 110. With this design, condensate flows into the room temperature water zone 110 through the overflow channel 1111 and the flow guiding structure 112. Through the flow path of the flow guiding structure 112, the liquid can be guided orderly into the room temperature water zone 110, ensuring that the liquid can enter the required location. Furthermore, it can also promote the mixing of the liquid with the room temperature water.

[0068] Specifically, refer to Figure 4 In this embodiment of the invention, the flow guiding structure 112 is a flow guiding channel, and the width of the flow guiding channel is adapted to the width of the overflow channel 1111. Through this design, since the width of the flow guiding channel is adapted to the width of the overflow channel 1111, condensate can smoothly flow into the room temperature water zone 110 through the flow guiding channel without encountering excessive resistance, achieving uniform liquid distribution and ensuring that the liquid maintains a certain speed and direction during flow.

[0069] Specifically, refer to Figure 4 and Figure 5 In this embodiment of the utility model, the condensation tank 111 is located outside the room temperature water zone 110, which helps to avoid heat exchange between the condensation tank 111 and the room temperature water zone 110 and achieves spatial separation.

[0070] Of course, in some embodiments of this utility model, the ice-making water dispenser may also be designed without a heating tank 700. It can be understood that the room temperature water zone 110 is directly connected to the water outlet valve 120. After water is added to the room temperature water zone 110 by the diaphragm pump 810, room temperature water is output to the first water outlet through the water outlet valve 120 to provide room temperature water to the user. This is not limited here.

[0071] Understandably, referring to Figures 3 to 4 In this embodiment of the invention, the ice-making water dispenser includes a water tank assembly, which includes a tank body 910 and a tank cover 920. The tank body 910 has a recessed interior forming a chamber with an upper opening. Within the chamber of the tank body 910, a room temperature water zone 110 and a cold water zone 210 are formed by a partition structure 500. Above the cold water zone 210 are an ice-making box 310, an ice-receiving trough 320, and an ice-storage trough 330. Both the ice-receiving trough 320 and the ice-storage trough 330 are located below the ice-making box 310. The ice-receiving trough 320 is used to receive ice cubes made in the ice-making box 310, and the ice-storage trough 330 is used to receive ice cubes transferred from the ice-receiving trough 320, for use by the user. With this structure, the cold water in the cold water zone 210 facilitates the creation of a low-temperature environment for the ice-making box 310, the ice-receiving trough 320, and the ice-storage trough 330, making operation easier, the space arrangement more reasonable, and space-saving, thus simplifying the manufacture of the ice-making water dispenser.

[0072] Reference Figure 3 In this embodiment of the invention, the cover 920 is positioned over the opening of the chamber of the tank body 910, and the cover 920 is detachably connected to the tank body 910. With this structure, the chamber has an opening at the top, allowing the operator to easily arrange the water tank components and install parts, improving operational convenience. Because the cover 920 is detachably connected to the tank body 910, the operator can easily open the cover 920 for cleaning or maintenance, maintaining the hygiene and good condition of the water tank components. This ensures a secure and reliable connection between the cover 920 and the tank body 910, preventing accidental detachment or leakage.

[0073] Specifically, in some embodiments of this utility model, the connection between the cover 920 and the body 910 is a combination of snap-fit ​​connection and bolt connection; of course, in some embodiments, the connection between the cover 920 and the body 910 may be only a snap-fit ​​connection or only a bolt connection, etc., which is not limited here.

[0074] Specifically, refer to Figure 4 and Figure 5It should be noted that in this embodiment, the room temperature water zone 110 is provided with two first liquid level switches 610, and the cold water zone 210 is provided with two second liquid level switches 620. By providing two liquid level switches in each water zone, the risk of water overflowing from the cabinet 910 due to the failure of a single liquid level switch can be reduced, which is conducive to ensuring the normal use of the ice-making water dispenser and avoiding affecting the user experience.
