Description

Technical Field

[0001] The utility model relates to the technical field of drinking water, in particular to a drinking water pipeline system and a water dispenser. Background Art

[0002] Existing water dispensers are mainly divided into under-mounted water dispensers and top-mounted water dispensers. Since it is more convenient to replace the water source for under-mounted water dispensers, under-mounted water dispensers are mainly used in the current industry.

[0003] Under-mounted water dispensers are further divided into non-pressure water source water dispensers and pressure water source water dispensers according to whether the water supply source has pressure. Among them, the water supply source of non-pressure water source water dispensers is usually barreled water without pressure, while pressure water source water dispensers usually have a built-in filter system and use tap water with built-in pressure as the water supply source.

[0004] However, the above two types of under-mounted water dispensers cannot be used interchangeably with water sources. For example, when a non-pressure water source water dispenser is connected to a pressure water source (such as tap water), the excessive water pressure will directly impact and damage the suction pump or other internal components. The internal structure and layout of pressure water source water dispensers are usually designed based on the pressure and flow rate of the tap water system. When connected to a non-pressure water source (such as barreled water), it may cause the internal structure or layout to malfunction, or even damage the internal components of the water dispenser. In summary, the water supply method of existing under-mounted water dispensers is relatively single, usually only suitable for use with non-pressure water sources or pressure water sources. In the case where a single water source is short of water and cannot be replenished in time, the water dispenser will not be able to continue to provide drinking water.

[0005] In response to this, although there are under-mounted water dispensers with dual modes on the market, that is, they can be adapted to both non-pressure water sources and pressure water sources at the same time, most of them are equipped with two sets of drinking water pipeline systems to adapt to different water sources respectively, with a complex structure, which is not conducive to the convenience and miniaturization of the water dispenser.

[0029] Embodiment 1

[0030] Reference Figure 1 , a drinking water waterway system, which is sequentially connected with a water source, a buffer chamber 1, a water pump 2 and an outlet waterway 3 along a preset direction. The buffer chamber 1 is provided with an inlet 11 and an outlet 12. The outlet 12 is arranged at a lower position relative to the inlet 11. The water source is hermetically connected to the inlet 11 of the buffer chamber 1 for supplying water in a pressurized or non-pressurized form. The input end of the water pump 2 is hermetically connected to the outlet 12 of the buffer chamber 1. The outlet waterway 3 is connected to the output end of the water pump 2 and the outlet waterway 3 is connected with a water outlet 31 for terminal water outlet. In addition, the drinking water waterway system further includes a flow control channel, which is connected in series between the water source and the inlet 11. One end of it is hermetically communicated with the water source, and the other end is hermetically communicated with the inlet 11 for hermetically switching on and off the water connection between the water source and the buffer chamber 1. In this embodiment, when the water source supplies water in a pressurized form, the water source can specifically be a water pipe or a water inlet machine. When the water source supplies water in a non-pressurized form, the water source can specifically be a barreled water or an atmospheric pressure water tank.

[0031] During operation, when the water source supplies water in a non-pressurized form, the flow control channel can be in a normally open state or be synchronously opened and closed according to the operating state of the water pump 2 (that is, when the water pump 2 is operating, the flow control channel is connected to connect the water source and the water inlet 11; when the water pump 2 stops, the flow control channel closes to disconnect the water connection between the water source and the water inlet 11). When the water pump 2 starts, the flow control channel connects the water source and the water inlet 11. Since the buffer chamber 1 is sealed inside and its water inlet 11 and water outlet 12 are respectively sealed and connected to the water source and the water pump 2, the negative pressure generated by the water pump 2 can be transmitted to the water source through the buffer chamber 1, pumping out the water in the barreled water or the normal pressure water tank, passing through the buffer chamber 1, the water pump 2 in sequence and entering the water outlet channel 3, and finally discharging it outwards through the water outlet nozzle 31 for use.

[0032] When the water source supplies water in a pressurized form, the flow control channel can be synchronously opened and closed according to the operating state of the water pump 2. Specifically: when the water pump 2 starts, the flow control channel is synchronously opened to connect the water source and the buffer chamber 1. At this time, the water in the water source, that is, the water in the water supply pipe or the water inlet machine, will, under the action of pressure, pass through the flow control channel, enter the buffer chamber 1 from the top of the buffer chamber 1 through the water inlet 11, and flow out of the buffer chamber 1 through the water outlet 12 arranged at the bottom of the buffer chamber 1, that is, at a lower position relative to the water inlet 11, and is sent into the water outlet channel 3 under the negative pressure of the water pump 2, and finally discharged outwards through the water outlet nozzle 31. During this period, since the water inlet 11 is arranged at a higher position relative to the water outlet 12, the high-pressure water flow will rush into the buffer chamber 1 from top to bottom after passing through the water inlet 11, and release the pressure during the rushing process, and the internal space of the buffer chamber 1 buffers it, thus effectively alleviating the direct impact of the water source pressure on the subsequent internal components such as the water pump 2.

[0033] The drinking water channel system in this embodiment is provided with a buffer chamber 1 and a flow control channel, and adopts a sealed connection design. By buffering the pressurized water source through the buffer chamber 1, it can seamlessly switch and adapt to two types of water sources, non-pressurized (such as barreled water, normal pressure water tank) and pressurized (such as water supply pipe, water inlet machine), with a single set of drinking water channel system, and the overall structural design is simple, without redundant components or complex water channel conversion mechanisms, which is conducive to the realization of the convenience and miniaturization of the drinking fountain.

[0034] To further reduce the impact on the water pump and the water outlet stability under the pressurized water supply state of the water source, a constant pressure valve 13 is connected to the top of the buffer chamber 1 in this embodiment. The constant pressure valve 13 is normally closed and is used to open when the water source is under pressurized water supply and the water pump 2 starts. By exhausting air externally, the pressure in the buffer chamber 1 is kept constant, avoiding the situation of "when the water outlet pressure of the water source fluctuates greatly, resulting in the water inlet efficiency of the buffer chamber 1 being greater than the water pumping efficiency of the water pump 2, and generating pressure impact to squeeze the water pump 2". In addition, due to the presence of the constant pressure valve 13, it is beneficial to change the water intake method under the pressurized water supply state of the water source. That is, when the water pump 2 is in the shutdown state, the flow control channel and the constant pressure valve 13 can be opened to allow the water source to transport water into the buffer chamber 1 under its own pressure. After the water transportation is completed, the flow control channel is closed. When subsequent water is needed, the flow control channel is closed, the constant pressure valve 13 is opened, and the water pump 2 is started. The water pump 2 only needs to pump water from the water already stored in the buffer chamber 1, improving the water intake efficiency and reducing the time wasted waiting for the water source pressure to stabilize. Moreover, it can reduce the impact and wear on components such as the water pump 2, helping to extend the service life of the entire water dispenser and reducing the maintenance cost for users.

[0035] In this embodiment, the implementation structure of the flow control channel has diversity. For the consideration of automatic design, it is preferably that an electromagnetic valve is connected in series between the water source and the water inlet 11, and the flow control channel is formed in the electromagnetic valve. In addition, a flow control pump 4 can be used instead of the traditional electromagnetic valve to provide the above flow control channel. The flow control pump 4 can accurately adjust the flow rate and pressure of the water flow as needed, and is suitable for the water use requirements under the unstable pressurized water supply situation, ensuring the stable operation of the water supply system under different working conditions.

[0036] When storing water with the cooperation of the buffer chamber 1 under the pressurized water supply state of the water source and with the help of the constant pressure valve 13, in order to reduce and avoid the influence of water source pressure fluctuation on the water storage accuracy in the buffer chamber 1 and improve the water supply stability. In this embodiment, a water level detection component is arranged in the buffer chamber 1. During operation, when the flow control component is opened and the water source transports water to the buffer chamber 1, the water level detection component can detect the water level change in the buffer chamber 1. When the buffer chamber 1 reaches the rated water level, it cooperates with the control component to control the on-off of the flow control channel, realizing the automation of water transportation and stopping water transportation, and ensuring the consistency of the water level inside the buffer chamber 1 each time water is stored. The implementation structure of the water level detection component has diversity, and structures such as an optoelectronic sensing probe, a capacitive probe, or an ultrasonic probe can be selected.

[0037] In this embodiment, considering that the buffer chamber 1 functions to buffer the water flow, after the water in the water source enters the buffer chamber 1 under pressure, it will impact the inner wall of the buffer chamber 1 and the existing water surface, stirring up water splashes that cause error interference to the water level detection. To address this, in this embodiment, the water level detection assembly includes a mechanical float probe 14 and at least two groups of low water level probes 15. The two groups of low water level probes 15 are arranged at the bottom of the buffer chamber 1. The low water level probes 15 are selected from the above-mentioned optoelectronic sensing probes, capacitive probes or ultrasonic probes, and are used to detect the low water level of the buffer chamber 1 when the water pump 2 draws water, so as to cooperate with the control assembly to control the opening of the control channel to replenish water to the buffer chamber 1. The mechanical float probe 14 is arranged at the top of the buffer chamber 1 and is used to detect the high water level of the buffer chamber 1 when the flow control channel is opened to convey water to the buffer chamber 1. Through the above technical solution, the mechanical float probe 14 is located at the top and the mechanical float itself has mass, making it relatively less susceptible to water splash interference. The low water level probes 15 are arranged at the bottom, and the replenishment operation is triggered by detecting the water level drop, which can also avoid the influence of water splash interference on the detection result.

[0038] In addition, in this embodiment, the input ends of the water outlet nozzles 31 are respectively connected to a hot water path 32 and a cold water path 33. The hot water path 32 is provided with a heating element 34, and the cold water path 33 is provided with an electronic ice tank 35. The water outlet water path 3 includes a water outlet three-way valve 36. The water outlet three-way valve 36 is provided with a first port 361 communicating with the output end of the water pump 2, a first port 361 communicating with the hot water path 32, and a second port 362 communicating with the cold water path 33. Through the above technical solution, the hot water path 32 and the cold water path 33 are introduced. The heating element 34 is arranged in the hot water path 32, and the flowing water can be heated to a set temperature, enabling users to obtain hot water at any time according to their needs. The electronic ice tank 35 is equipped in the cold water path 33 and is used to cool the water flow. In summer or when cold water is needed, users can select the cold water path 33 to obtain cool drinking water or for other occasions requiring cold water, and the flexible switching of hot water, cold water and the water output by the water pump 2 is realized through the water outlet three-way valve 36.

[0039] Considering that if the water dispenser does not draw cold water for a long time, the water in the electronic ice tank 35 does not flow for a long time, and it is easy to breed bacteria, algae or other microorganisms and become stale water. To address this, in this embodiment, a drain valve 37 is provided at the bottom end of the electronic ice tank 35, and the drain valve 37 can be used to regularly drain the stale water stored in the electronic ice tank 35 to ensure fresh water quality.

[0040] In this embodiment, the water source includes a first water source 5 and a second water source 6. The first water source 5 is used for supplying water in a pressurized form, and the second water source 6 is used for supplying water in a non-pressurized form. The input end of the flow control channel is connected in parallel with a first connection valve 7 and a second connection valve 8. The first connection valve 7 is used to connect the first water source 5, and the second connection valve 8 is used to detachably and sealingly connect the second water source 6. Through the above solution, a stable connection can be formed with the pressurized first water source 5 through the first connection valve 7. When the first water source 5 runs out of water, without disassembling and releasing the connection between the first connection valve 7 and the first water source 5, the second water source 6 (such as barreled water) with non-pressurized water supply can be quickly and detachably connected through the second connection valve 8, improving the emergency response ability of water supply.
