Abstract
Description
Technical Field
[0001] This utility model relates to the field of water supply equipment technology, and in particular to a water supply device. Background Technology
[0002] Existing water supply systems can provide hot, cold, and ambient temperature water, making them convenient to use. Hot water can be heated through heat exchange, direct heating, or a combination of both. Heat exchange heating typically involves storing hot water in a hot tank and exchanging heat with water from the source via a heat exchanger to heat the drinking water. Cold water, on the other hand, is generally cooled and stored in a cold tank for later supply when needed.
[0003] Current water supply systems, in order to prevent bacterial growth and ensure safety, generally require periodic or scheduled drainage of the cold water stored in the cold tanks. Existing systems typically have drainage pipes on the hot tanks but not on the cold tanks. This necessitates manual handling of the cold water in the cold tanks, which is inconvenient. Alternatively, adding drainage pipes to the cold tanks would increase piping complexity, making the overall structure larger and increasing costs. Utility Model Content

[0033] A water supply system is a common household or commercial water supply device that provides users with instant hot water, cold water, and room temperature water. It is convenient to use and widely popular. Existing water supply systems that supply cold water use a cold tank to cool and store the water. To ensure the "freshness" of the cold water, a drain pipe is usually installed for a separate cold tank to change the water periodically or irregularly. This increases the number of pipes and the overall structural complexity of the water supply system, as well as the manufacturing difficulty and cost, and also hinders the integration and miniaturization of the system.
[0034] In view of this, the present invention provides a water supply device, which includes a first tank, a second tank, and a water pipe. A first water inlet and a second water inlet are respectively provided on the first tank and the second tank, and then the first water inlet and the second water inlet are connected by the water pipe. When it is necessary to replace the water in the first tank, the water in the first tank is first transported to the second tank through the water pipe, and then discharged.
[0035] Please see Figure 1 and Figure 2 As shown in the figure, a water supply device 1 provided in this embodiment of the present invention includes a first tank 10, a second tank 20, and a water guide pipe 30. The first tank 10 is used for cooling and storing cooling water and is provided with a first water guide port (not shown). The second tank 20 is used for storing heat exchange water and is provided with a drainage device (not shown) and a second water guide port (not shown). One end of the water guide pipe 30 is connected to the first water guide port, and the other end of the water guide pipe 30 is connected to the second water guide port, for transporting the water in the first tank 10 to the second tank 20. The second tank 10 or the water guide pipe 30 is provided with a drainage device (not shown).
[0036] In one embodiment, the first water inlet is located at or near the bottom of the first tank, and / or the second water inlet is located at or near the bottom of the second tank. Specifically, by setting the first water inlet and the second water inlet at or near the bottom of the first tank 10 and the second tank 20 respectively, it is beneficial to drain the water from the bottom of the first tank 10 and the second tank 20, thereby achieving the effect of sufficient liquid replacement.
[0037] In one embodiment, the bottom of the first tank 10 is higher than the bottom of the second tank 20. Specifically, by positioning the bottom of the first tank 10 higher than the bottom of the second tank 20, it is advantageous to utilize the pressure of the water to transport the water from the first tank 10 to the second tank 20 through the water pipe 30.
[0038] In one embodiment, the drainage device is located at or near the bottom of the second tank 20.
[0039] In one embodiment, the first can 10 is a cold can and the second can 20 is a hot can.
[0040] Understandably, when hot water is needed, the heat exchange water stored in the second tank 20 exchanges heat with drinking water from the water source, rapidly heating the drinking water before it is delivered to the user's tap. The heat exchange water stored in the second tank 20 is also replaced periodically, thus it has a drainage pipeline. When cold water is needed, the drinking water cooled by the first tank 10 is delivered to the user. The first tank 10 also stores cold water, ensuring the water remains cooled during prolonged use; therefore, it needs to be replaced periodically to maintain the water's "freshness." The water in the first tank 10 can be transported to the second tank 20 via the water pipe 30, and then discharged through the second tank 20. The water source can be drinking water filtered through an RO filter.
[0041] The water supply device 1 further includes a first valve body, which is disposed on the water guide pipe 30 and used to control the opening and closing of the water guide pipe 30. The first valve body is an on / off valve or a one-way valve, used to allow water to flow out of the first tank in one direction. In this embodiment, preferably, the first valve body is a one-way valve.
[0042] Understandably, in the water purification device 1, the heat exchange water stored in the second tank 20 also comes from a drinking water source. However, since it mainly serves as a heat exchange medium, it should not be allowed to mix with the cooling water in the first tank 10, which is used as direct drinking water, as this would "contaminate" the cooling water in the first tank 10. Furthermore, if the heat exchange water in the second tank 20 were allowed to flow into the first tank 20, it would cause two problems: firstly, the hot water in the heat exchange water might damage the first tank 10; secondly, it might cause the cooling water in the first tank 10 to heat up, affecting its taste. Therefore, the heat exchange water in the second tank 20 should not flow into the first tank 10. By installing the one-way valve inside the water guide pipe 30, only the water (cooling water) in the first tank 20 is allowed to flow unidirectionally to the second tank 30, preventing the heat exchange water in the second tank 20 from flowing into the first tank 20, thereby preventing the heat exchange water from "contaminating" the cooled drinking water in the first tank 20. In some other embodiments, other components can also be used to achieve unidirectional water flow, which is not limited here.
[0043] Please see Figure 1 and Figure 3 The water supply device 1 further includes a water circuit board 50, which includes a drain pipe 501 and a pump body 502. The drain pipe 501 is connected to the drainage device and is used to discharge water from the second tank 20. The pump body 502 is located in the drain pipe 501 and is used to provide power for the flow of water in the drain pipe 501.
[0044] Understandably, when it is necessary to discharge the heat exchange water in the second tank 20 or the cooling water from the first tank 10, the pump body 502 operates, driving this portion of water from the second tank 20 through the drainage device into the drainage pipe 501, and then discharges it. The water supply device 1 can be manually operated to control the operation of the pump body 502, or it can be set to operate automatically at a timer. Preferably, the pump body 502 is an electric pump.
[0045] Please refer to further information. Figure 3 In one embodiment, the water circuit board 50 further includes a back suction pipe 503, one end of which is connected to the water supply end, and the other end of which is connected to the drain pipe 501. The back suction pipe 503 is used to transport water from the water supply end to the drain pipe 501, and the drain pipe 501 is also used to discharge water from the water supply end.
[0046] The water circuit board 50 further includes a three-way valve 504, which includes a first inlet (not shown), a second inlet (not shown), and an outlet (not shown). The first inlet is connected to the drainage device, the second inlet is connected to the back suction pipe 503, and the outlet is connected to the drainage pipe 501. The three-way valve 504 is used to control the connection between the drainage pipe 501 and the drainage device 201 or between the drainage pipe 501 and the back suction pipe 503.
[0047] Understandably, the water supply device 1 has water supply modes, such as a hot water mode supplying hot water, a cold water mode supplying cooling water, and a normal temperature mode supplying normal temperature water. When changing the water supply mode, for example, when a user switches from using hot water to using cold water, hot water (or water left over from the previous use) often remains at the water outlet. If this water is directly drained from the water outlet, a waiting period is required, which leads to a poor user experience. By setting up the back suction pipe 503, this water can be transported from the water outlet to the drain pipe 501. This water remaining at the water outlet enters from the back suction pipe 503 through the first inlet of the three-way valve 504, and then exits through the outlet of the three-way valve 504 into the drain pipe 501 for discharge.
[0048] The water circuit board 50 also includes a water output pipe 505 and a water input pipe 506. The water output pipe 506 is used to connect the water outlet and the hot water supply circuit (not shown in the figure) to the water outlet. The water input pipe 506 is used to connect the water source and the water inlet of the hot water supply circuit. The water output pipe 505 and the water input pipe 506 are connected.
[0049] Specifically, the water output pipe 505 and the water input pipe 506 are connected by a two-way valve body. This type of valve body can control the on / off state of the pipes, and can also be connected through other devices; no restrictions are placed here. When room temperature drinking water is used, room temperature water from the water source enters through the water input pipe 506, then enters the water output pipe 505 and is delivered to the user. When hot water is used, hot water flows into the outlet pipe 506 through the outlet end of the hot water supply circuit and is delivered to the user.
[0050] In one embodiment, the water circuit board 50 further includes a water supply pipe 507, and the first tank 10 is also provided with a water inlet 102; one end of the water supply pipe 507 is connected to the water output pipe 505, and the other end of the water supply pipe 507 is connected to the water inlet.
[0051] Specifically, due to usage or periodic replacement, the first tank 10 needs to be replenished with water periodically or irregularly. Water from the water source enters the water output pipe 505 through the water inlet pipe 506, flows into the first tank 10 through the water replenishment pipe 507 and the inlet, replenishing the first tank 10 with water. The heat exchange medium can exchange heat with the water from the water source to raise the temperature of the water. Before the heat exchange medium exchanges heat with the water, the high temperature easily leads to the formation of steam, thus reducing the amount of heat exchange medium in the second tank 20, requiring periodic or irregular replenishment. In this situation, the second tank 20 cannot be replenished with water from the outside, and its internal water pressure will drop. When the water pressure in the first tank 10 is greater than the water pressure in the second tank 20, the first tank 10 can replenish the second tank 20 with water as a heat exchange medium through the water guide pipe 30.
[0052] Please refer to it again. Figure 1 and Figure 4 In another embodiment, the second tank 20 is further provided with a water inlet (not shown). The water supply pipeline 507 includes a first water supply branch 5071 and a second water supply branch 5072, both of which are connected to the water output pipeline 505. The end of the first water supply branch 5071 furthest from the water output pipeline 505 is connected to the water inlet for replenishing water to the first tank 10. The end of the second water supply branch 5072 furthest from the water output pipeline is connected to the water inlet for replenishing water (heat exchange medium) to the second tank 20.
[0053] Understandably, when water can be replenished to both the first tank 10 and the second tank 20 separately, the water to be replenished will flow from the water inlet pipe 506, through the water outlet pipe 505, to the first water replenishment branch 5071 and the second water replenishment branch 5072 respectively, and then through the water inlet and the water replenishment inlet respectively, finally flowing into the first tank 10 and the second tank 20 respectively, thus replenishing the water for the first tank 10 and the second tank 20.
[0054] In one embodiment, the water circuit board 50 further includes a one-way valve 508, which is located in the second water supply branch 5072 and allows water to flow unidirectionally from the water output pipe 505 to the second tank 20. Specifically, when replenishing water to the second tank 20, if more water is supplied after the second tank 20 is full, the water in the second tank 20 will overflow, flowing through the second water supply branch 508 and then through the first water supply branch 507 into the first tank 10 via the inlet, thus "contaminating" the cold water in the first tank 10. The one-way valve 508 prevents water from overflowing from the second tank into the first tank 10, avoiding "contamination" during the water replenishment process.
[0055] The above description is only a preferred embodiment of the utility model and does not limit the patent scope of the utility model. All equivalent structural transformations made under the utility model concept and based on the contents of the utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the utility model.
