[0026] The above-described one or more technical solutions in the embodiments of this utility model have at least one of the following technical effects:

[0027] This application simplifies the overall structure of the drainage system by unifying the cold water and hot water drainage pipes into the main drainage pipe, thus avoiding the need for multiple drain outlets and scattered drainage paths. Furthermore, since the cold and hot water drainage pipes share the same main drainage pipe, the layout of the entire drainage system becomes more compact, reducing the space occupied by the drainage pipes inside the machine. Simultaneously, integrating cold and hot water drainage into a single main drainage pipe effectively simplifies the drainage process, making the pipe layout more rational and helping to avoid installation and maintenance inconveniences caused by pipe crossings or overlaps, while also reducing the potential risk of leakage.

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.

[0042] When existing ice-making and water-making machines need to be shut down for a period of time, the internal water must be drained before shutdown. Alternatively, after the machine has been used for a period of time, the internal water-contacting parts need to be cleaned with citric acid water, and the cleaning water also needs to be drained.

[0043] However, in related technical fields, cold and hot water for ice-making and drinking water are often supplied through separate pipelines, resulting in a dispersed pipeline structure and an unreasonable layout.

[0044] The following is combined Figures 1 to 3 The ice-making water dispenser provided in this utility model will be described in detail through specific embodiments and application scenarios.

[0045] Please refer to the ice-making water dispenser 10 proposed in the embodiments of this application. Figure 1 and Figure 3 The ice-making water dispenser 10 includes a body 100, a cold water tank 110, a cold water drain pipe 120, a heating tank 130, a hot water drain pipe 140, and a main drain pipe 150. The cold water tank 110 is mounted on the body 100; the cold water drain pipe 120 is connected to the cold water tank 110; the heating tank 130 is mounted on the body 100; the hot water drain pipe 140 is connected to the heating tank 130; and the main drain pipe 150 is connected to both the cold water drain pipe 120 and the hot water drain pipe 140.

[0046] The main body 100 is the supporting structure for the entire ice-making water dispenser 10, providing protection and support for the various internal components. It is usually an outer shell, used to house and secure all internal parts, while also providing a user operation window.

[0047] The cold water tank 110 is used to store cooled water or collect leftover cold water from ice making for direct drinking or recycling in ice production. The cold water tank 110 can be equipped with a refrigeration device, such as a compressor refrigeration system, to ensure the water temperature is maintained at a suitable low temperature. The cold water tank 110 is connected to the main drain pipe 150 via a cold water drain pipe 120 to drain water from the cold water tank 110 when needed.

[0048] The cold water drain pipe 120 connects the cold water tank 110 and the main drain pipe 150, and is used to drain the water from the cold water tank 110. When the machine is not in use or is being cleaned, the water in the cold water tank 110 can be completely drained through the cold water drain pipe 120 to prevent bacterial growth or other problems caused by water accumulation. One end of the cold water drain pipe 120 is connected to the cold water tank 110, and the other end is connected to the main drain pipe 150.

[0049] Heating tank 130 is used to store and heat water, providing hot water for users to drink. Heating tank 130 is typically equipped with an electric heating element that can heat the water to a set temperature. Heating tank 130 is connected to main drain line 150 via hot water drain line 140 so that water in heating tank 130 can be drained when needed.

[0050] The hot water drain pipe 140 connects the heating tank 130 and the main drain pipe 150, and is used to drain the water from the heating tank 130. When the machine is not in use or is being cleaned, the water in the heating tank 130 can be completely drained through this pipe to prevent high-temperature water from causing damage to the machine's internal components or posing a safety hazard. One end of the hot water drain pipe 140 is connected to the heating tank 130, and the other end is connected to the main drain pipe 150.

[0051] The main drain pipe 150 serves as the common outlet for both the cold water drain pipe 120 and the hot water drain pipe 140, concentrating the water discharged from both and discharging it from the machine through a single drain outlet 212. This simplifies the drainage system design, reduces the number of drain outlets 212, and improves drainage efficiency. The main drain pipe 150 connects to both the cold water drain pipe 120 and the hot water drain pipe 140, ultimately discharging the water outside the machine.

[0052] This application simplifies the overall structure of the drainage system by unifying the cold water drainage pipe 120 and the hot water drainage pipe 140 into the main drainage pipe 150, thus avoiding the need for multiple drain outlets 212 and scattered drainage paths. Furthermore, since the cold water drainage pipe 120 and the hot water drainage pipe 140 share the same main drainage pipe 150, the layout of the entire drainage system becomes more compact, reducing the space occupied by the drainage pipes inside the machine. At the same time, by integrating the cold water drainage and hot water drainage into a single main drainage pipe 150, the drainage process can be effectively simplified, making the pipe layout more reasonable. This helps to avoid inconvenience in installation and maintenance caused by pipe crossings or overlaps, and also reduces the potential risk of leakage.

[0053] Reference Figure 3According to one embodiment of the present invention, the ice-making drinking water also includes a drain valve 200, which is disposed on the main drain pipe 150. The drain valve 200 has a drain outlet 212, a first interface 213 and a second interface 214. The first interface 213 and the second interface 214 are respectively connected to the drain outlet 212. The first interface 213 is connected to the cold water drain pipe 120 and the second interface 214 is connected to the hot water drain pipe 140.

[0054] It is understood that in this embodiment, the drain valve 200 is a switch valve that controls the discharge of water from inside the machine. The drain valve 200 is installed on the main drain pipe 150 and can control the discharge of water by opening or closing it.

[0055] Drain outlet 212 is the outlet from which drain valve 200 discharges water from the machine.

[0056] The first interface 213 is the part that connects the drain valve 200 to the cold water drain pipe 120. It is used to ensure that water in the cold water drain pipe 120 can be discharged by opening the drain valve 200. The first interface 213 is separately connected to the drain outlet 212 to ensure that cold water is discharged only through the drain valve 200 and will not mix with hot water.

[0057] The second interface 214 is the part that connects the drain valve 200 to the hot water drain pipe 140. It is used to ensure that water in the hot water drain pipe 140 can be discharged by opening the drain valve 200. The second interface 214 is separately connected to the drain outlet 212 to ensure that hot water is discharged only through the drain valve 200 and to avoid mixing with cold water.

[0058] In this way, by connecting the first interface 213 and the second interface 214 separately to the drain outlet 212, it is ensured that cold water and hot water will not mix before entering the drain valve 200, thus avoiding the cold water being heated by the hot water or the hot water being cooled by the cold water, thereby ensuring the purity of the water quality.

[0059] Reference Figure 3 According to one embodiment of the present invention, the drain valve 200 includes a valve body 210 and a valve core 220. The valve body 210 has a valve cavity 211 communicating with a first interface 213 and a second interface 214. The valve core 220 is disposed in the valve cavity 211 and forms a first flow channel 221 and a second flow channel 211a. The first flow channel 221 communicates between the first interface 213 and the drain outlet 212, and the second flow channel 211a communicates between the second interface 214 and the drain outlet 212.

[0060] Understandably, the valve body 210 has a valve cavity 211, and at least two interfaces, namely a first interface 213 and a second interface 214, which are respectively connected to the cold water drain pipe 120 and the hot water drain pipe 140 for introducing cold or hot water into the valve cavity 211. In addition, the valve body 210 also has a drain port 212 for discharging fluid from the valve cavity 211.

[0061] A valve core 220 is disposed within a valve chamber 211, dividing the chamber into two relatively independent flow channels: a first flow channel 221 and a second flow channel 211a. The first flow channel 221 connects the first port 213 to the drain port 212. When fluid at the first port 213 needs to be discharged, it flows through the first flow channel 221 into the drain port 212. The second flow channel 211a connects the second port 214 to the drain port 212. When fluid at the second port 214 needs to be discharged, it flows through the second flow channel 211a into the drain port 212.

[0062] This allows the drain valve 200 to flexibly control the fluids flowing in from different interfaces and discharge them through the same drain port 212, preventing hot water from entering the cold water circuit.

[0063] According to one embodiment of the present invention, the valve core 220 extends along the first interface 213 toward the drain outlet 212, the first flow channel 221 is formed inside the valve core 220, and the second flow channel 211a is formed on the outside of the valve core 220.

[0064] It is understood that in this embodiment, the valve core 220 extends along the first interface 213 toward the drain port 212 to guide and distribute the flow channels inside the valve cavity 211. The first flow channel 221 is located inside the valve core 220 and can serve as a discharge channel for either cold or hot water. The second flow channel 211a is formed on the outside of the valve core 220, representing the remaining flow channel. Because it is on the outside of the valve core 220, it is physically isolated from the first flow channel 221, preventing mixing between the two.

[0065] Reference Figure 3 According to one embodiment of the present invention, the first flow channel 221 and the second flow channel 211a are coaxially arranged.

[0066] Understandably, the coaxial arrangement of the first flow channel 221 and the second flow channel 211a allows for a more compact overall structure of the drain valve 200, reducing space occupancy. Simultaneously, since the first flow channel 221 and the second flow channel 211a share a common axis, the fluid flow between them can be smoother and more continuous, reducing turbulence and resistance during flow, thereby improving drainage efficiency.

[0067] Reference Figure 3According to one embodiment of the present invention, an abutment step 215 is formed on the inner wall of the valve cavity 211 near the first interface 213, and one end of the valve core 220 abuts against the abutment step 215.

[0068] Understandably, the abutment step 215 provides a positioning point for the valve core 220. When the valve core 220 is installed into the valve cavity 211, one end of it naturally abuts against this step, thus ensuring the correct position of the valve core 220 within the valve cavity 211. This helps maintain a stable relative position between the valve core 220 and the valve cavity 211, preventing displacement or deflection of the valve core 220 under fluid pressure. The abutment point between the abutment step 215 and the valve core 220 forms a sealing interface. When the valve core 220 is tightly abutted against the step, fluid leakage from the gap between the valve core 220 and the valve cavity 211 is effectively prevented.

[0069] Reference Figure 3 According to one embodiment of the present invention, the drain valve 200 further includes a sealing ring 230, which is sleeved on the end of the valve core 220 near the abutting step 215 and abuts against the inner wall of the valve core 220 and the valve cavity 211.

[0070] Understandably, the main function of the sealing ring 230 is to enhance the sealing performance of the drain valve 200. When the valve core 220 is installed in the valve cavity 211, the sealing ring 230 is compressed between the valve core 220 and the inner wall of the valve cavity 211, filling the tiny gap between the valve core 220 and the valve cavity 211. This effectively prevents fluid from leaking out from any tiny gap between the valve core 220 and the valve cavity 211, thus improving the sealing performance.

[0071] Reference Figure 3 According to one embodiment of the present invention, a flow-slowing part 222 is provided on the outer wall surface of the valve core 220 near the drain port 212.

[0072] Understandably, the main function of the flow-slowing section 222 is to slow down the fluid velocity as it approaches the drain outlet 212. When the fluid flows through the valve core 220 and approaches the drain outlet 212, the protruding shape of the flow-slowing section 222 forces the fluid to change its flow direction and disperse the flow, thereby reducing the flow rate to prevent the user from being scalded when opening the drain valve 200 and improving safety.

[0073] Reference Figure 3 According to one embodiment of the present invention, the drain valve 200 further includes a rubber plug 240, which is sealed at the drain outlet 212 and abuts against the end of the valve core 220 near the drain outlet 212.

[0074] Understandably, the rubber stopper 240 is primarily used to seal the drain port 212 to prevent fluid from leaking out of the drain valve 200 when drainage is not required. When the drain valve 200 is closed, the rubber stopper 240 fits tightly against the drain port 212, forming a reliable sealing interface. The rubber stopper 240 abuts against the end of the valve core 220 near the drain port 212 to further secure the valve core 220 in the valve cavity 211. By using the rubber stopper 240 to seal the drain port 212, the sealing performance of the drain valve 200 can be further enhanced.

[0075] Reference Figure 3 According to one embodiment of the present invention, the drain valve 200 further includes a screw cap 250. The valve body 210 is provided with an external thread on the outer side corresponding to the drain port 212, which cooperates with the screw cap 250. The screw cap 250 and the valve body 210 are threadedly engaged to seal and press the rubber plug 240 against the drain port 212.

[0076] Understandably, the screw cap 250 is located on the outside of the valve body 210, corresponding to the drain port 212. The screw cap 250 is used to seal and press the rubber plug 240 onto the drain port 212 by engaging with the external thread of the valve body 210, thereby ensuring the sealing of the drainage system. The screw cap 250 typically has an internal thread that matches the external thread on the valve body 210 so that the screw cap 250 can be tightened.

[0077] When it is necessary to seal the drain outlet 212, tighten the cap 250 onto the valve body 210. The internal thread of the cap 250 interacts with the external thread of the valve body 210, generating inward pressure. This presses the rubber plug 240 onto the drain outlet 212, forming a seal to prevent fluid leakage. When drainage is needed, loosen the cap 250, pull out the rubber plug 240, and open the drain outlet 212.

[0078] According to one embodiment of the present invention, the body 100 is provided with an installation port, the drain port 212 extends outward from the installation port, and the screw cap 250 is screwed onto the extended part of the drain port 212.

[0079] Understandably, the mounting port on the body 100 facilitates the installation of the drain valve 200. The drain port 212 extends outward from the mounting port, making the drain valve 200's drainage function more direct and efficient. When the drain valve 200 is open, fluid can flow directly from the drain port 212 without passing through complex pipes or channels. Simultaneously, the protruding portion of the drain port 212 provides sufficient space and position for the screw cap 250 to be screwed on, allowing the screw cap 250 to be tightly pressed against the drain port 212, achieving a good sealing effect.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
