Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

According to an aspect of the present invention, there is provided a waterway system, as shown in fig. 1. The waterway system may include a water inlet end 11, a first water outlet end 12, and a second water outlet end 13. The water inlet end 11 may be used to connect a water tank or municipal water line. The first outlet end 12 and the second outlet end 13 can be used to connect a faucet or any other means of accessing water.

The waterway system may also include a first heating module 100 and a second heating module 200. The first and

second heating modules

100 and 200 may be independent heating modules.

The first heating module 100 may include a first water storage means 110 and a first heating means 120. The first water storage means 110 may be connected between the water inlet end 11 and the first water outlet end 12. The first heating means 120 may be used to heat the water in the first water storage means 110. In some embodiments, the first water storage device 110 may include any type of water tank or container that can store water. The first heating device 120 may include any heater, such as a resistance heater, an electromagnetic heater, or an infrared heater. The user can receive the hot water from the first water outlet end 12 to the first water storage device 110.

The second heating module 200 may include a pre-heat assembly 210 and a second heating device 220. The inlet of the preheating assembly 210 may be connected to the inlet end 11. The outlet of the preheating assembly 210 can be connected to the second outlet end 13. The second heating device 220 may be used to heat the water flowing out of the preheat assembly 210. The preheating assembly 210 and the first water storage device 110 may be thermally coupled. In the second heating module 200, water may enter through the inlet end 11, pass through the pre-heating assembly 210, and exit through the second outlet end 13. Since the preheating unit 210 and the first water storage device 110 may be thermally coupled, the first water storage device 110 may exchange heat with water flowing through the preheating unit 210. During the heat exchange, the first water storage device 110 may raise the temperature of the water in the preheating assembly 210, thereby increasing the initial temperature of the water entering the second heating device 220. The second heating device 220 may comprise any heater, and when the water flows out from the preheating assembly 210, the second heating device 220 can continue to heat based on the initial water temperature after heat exchange with the first water storage device 110, so as to achieve the purpose of rapidly increasing the water temperature at the second water outlet end 13. The preheating assembly 210 may be a pipeline disposed upstream of the second heating device 220, or may be a water passing device disposed upstream of the second heating device 220. The preheating assembly 210 may be disposed outside the first water storage device 110, and the temperature of the water flow inside the preheating assembly 210 is increased by the heat diffused outward from the first water storage device 110. The preheating unit 210 may be disposed inside the first water storage device 110, and soaked in the water in the first water storage device 110, so as to raise the temperature of the water flow in the preheating unit 210 by the temperature of the water in the first water storage device 110. It is understood that the outlet temperatures of the first outlet end 12 and the second outlet end 13 are not particularly limited. The temperature of the water at the first water outlet end 12 can be higher or lower than the temperature of the water at the second water outlet end 13, as long as the temperature of the water flowing into the preheating assembly 210 can be increased by the first water storage device 110.

Therefore, with the waterway system provided by the embodiment of the present invention, the user can receive the hot water flowing out from the first heating module 100 through the first water outlet end 12, and the user can also receive the hot water flowing out from the second heating module 200 through the second water outlet end 13. Since the preheating assembly 210 is disposed in the second heating module 200, and the preheating assembly 210 is thermally coupled to the first water storage device 110, the water flow in the preheating assembly 210 can exchange heat with the first water storage device 110, so as to increase the temperature of the water flowing out of the preheating assembly 210. Because the temperature of the water flowing out of the preheating assembly 210 is increased, the water temperature rising rate of the second water outlet end 13 can be increased on the basis that the heating power of the second heating device 220 is not changed, so that the water outlet quantity of the hot water is increased, and the water outlet time of the hot water is shortened. In addition, because the water flowing out of the second water outlet end 13 is preheated by the preheating assembly 210, the temperature of the water entering the second heating device 220 is increased, so that the heating power of the second heating device 220 can be properly reduced under the condition that the temperature of the water flowing out of the second water outlet end 13 is not changed, and the volume of the second heating device 220 is reduced, thereby not only reducing the energy consumption, but also reducing the size of the product and reducing the cost of the product. In some embodiments, if the first heating module 100 is a thermostat and the second heating module 200 is an instant heating device, the instant heating device can increase the heating rate by using the thermostat, so as to achieve effective utilization of the thermostat and the instant heating device.

Illustratively, the preheat component 210 may include a preheat circuit. At least a portion of the pre-heating circuit may be disposed in the first water storage device 110. In some embodiments, the preheating circuit may be immersed in the water in the first water storage device 110, and the water flowing through the preheating circuit is heated by the temperature of the water in the first water storage device 110. It will be appreciated that the temperature of the water flow in the pre-heating circuit does not necessarily rise to the same temperature as the water in the first water storage means 110, since the water flow in the pre-heating circuit has a certain velocity, but only to increase the temperature of the water flow in the pre-heating assembly 210. The waterway system with the setting has simple structure and is easy to realize.

Illustratively, the waterway system may further include a first controller. The first controller may be electrically connected with the first heating device 120 and the second heating device 220. The first controller may be used to control the first heating means 120 to stop operating while the second heating means 220 is operating. In the embodiment where the second heating device 220 is a tankless heating device, since the tankless heating device requires a larger power and a shorter time, the first heating device 120 may be controlled to stop operating while the second heating device 220 is operating in order to reduce the load of the user circuit. In addition, since the second heating device 220 is operated for a short time, the first heating device 120 is stopped for a relatively short time, so that the initial temperature of the water flowing into the second heating device 220 can be increased by the first water storage device 110 without causing an excessive influence on the temperature of the water in the first water storage device 110.

The first controller can be built by electronic components such as a timer, a comparator, a register, a digital logic circuit and the like, or can be realized by processor chips such as a singlechip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC) and the like and peripheral circuits thereof

Illustratively, the waterway system may further include a central filter assembly 300. The central filter assembly 300 may include any filter element, whether existing or external, such as a carbon fiber filter element, a PP filter element, a ceramic filter element, or a composite filter element formed by combining a plurality of filter elements. The water inlet of the central filter assembly 300 may be connected to the water inlet end 11. The water outlet of the central filter assembly 300 may be connected to the water inlet of the second heating module 200. The inlet of the first heating module 100 may be connected to a line between the inlet end 11 and the inlet of the central filter assembly 300. That is, the central filter assembly 300 may filter the water flow entering the second heating module 200. In some embodiments, the central filter assembly 300 may filter raw water at the water inlet end 11 to generate drinking water for drinking by a user. Through the heating of the second heating module 200, the user can take the hot water from the second water outlet end 13 and drink the hot water directly, so that the use experience of the user is improved. It is understood that, since the central filter assembly 300 filters the raw water, scale generated in the second heating module 200 may be reduced when the water flows into the second heating module 200 for heating, thereby extending the life span of the second heating module 200.

Illustratively, the waterway system may further include a second controller. Wherein, the second controller can be the same as the first controller, and each controller is arranged independently. The second controller may also be the same controller as the first controller. The second heating device 220 may comprise an instantaneous water heater. Tankless water heaters can rapidly increase the temperature of the water flowing through them. The second heating module 200 may also include a flow control assembly 230 electrically connected to the second controller. Flow control assembly 230 may be connected between the outlet of central filter assembly 300 and pre-heat assembly 210. The second controller can also be used to control the water outlet flow of the flow control assembly 230 according to the water intake temperature of the user. In some embodiments, flow control assembly 230 may include a flow control pump or a flow control valve, or the like. Under the condition that the power of the second heating device 220 is not changed, the larger the flow rate of the water flowing through the second heating device 220 is, the lower the temperature of the water outlet at the second water outlet end 13 is, and the smaller the flow rate of the water flowing through the second heating device 220 is, the higher the temperature of the water outlet at the second water outlet end 13 is. Thus, the temperature of the second outlet end 13 can be controlled by the outlet flow of the flow control assembly 230. In addition, because the central filtering component 300 is further disposed in the waterway system, the second heating module 200 can be prevented from being influenced by the water outlet flow rate of the central filtering component 300 by the control of the flow control component 230, so as to stabilize the water outlet temperature and the water outlet flow rate of the second water outlet end 13.

Illustratively, the flow control assembly 230 may include a second water storage device 231 and a flow control pump 232 arranged in sequence along the water flow direction. The second water storage 231 may include a water tank or a pressure tank, etc. The second water storage 231 is used for temporarily storing the water filtered by the central filter assembly 300. If the water flow rate of the central filtering assembly 300 is greater than the water flow rate required by the second heating device 220, the filtered water may be temporarily stored in the second water storage device 231 and pumped out by the flow control pump 232 to be supplied to the second heating device 220. In this way, frequent activation of the central filter assembly 300, resulting in loss of electrical power, is avoided. In addition, in the case that the water flow rate required by the second heating device 220 is less than the water outlet flow rate of the central filter assembly 300, the damage to the central filter assembly 300 caused by the increase of the back pressure at the water outlet of the central filter assembly 300 can be avoided.

For example, the second water storage device 231 may include a pressure tank. The center filter assembly 300 may include a booster pump 310 and a reverse osmosis filter element 320, which are sequentially disposed in a water flow direction. A high pressure switch 400 may be provided on the line between the outlet of the central filter assembly 300 and the pressure tank. The second controller may also be configured to control the start and stop of the booster pump 310 according to the on and off of the high voltage switch 400. The pressure barrel can provide a certain squeezing force. The pure water prepared by the reverse osmosis filter element 320 may be first stored in a pressure tank. When the pressure of the pressure barrel reaches the preset threshold value, the high-voltage switch 400 is switched off, the booster pump 310 can stop working, and the reverse osmosis filter element 320 stops preparing pure water. The flow control pump 232 may pump pure water from the pressure tank to the second heating device 220. During the process of pumping pure water by the flow control pump 232, the pressure in the pressure barrel will be gradually released, when the pressure in the pressure barrel is reduced to the pressure at which the high-pressure switch 400 is closed, the high-pressure switch is closed, the booster pump 310 starts to work, and the reverse osmosis filter element 320 can continue to prepare pure water and store the pure water in the pressure barrel. Therefore, with the water path system, when a user takes water from the second water outlet end 13, the long-time operation or frequent start and stop of the booster pump 310 can be avoided, so as to prolong the service life of the booster pump 310. In addition, since the booster pump 310 does not always provide high-pressure raw water to the reverse osmosis filter element 320, the water outlet of the reverse osmosis filter element 320 does not have high back pressure, and damage to the reverse osmosis filter element 320 is reduced.

In some embodiments, the waterway system may further include a first temperature sensor 510. The first temperature sensor 510 may be disposed between the preheat assembly 210 and the second heating device 220. The second controller may also be used to control one or more of the outflow of water from the flow control assembly 230 and the power of the second heating device 220 based on the temperature detected by the first temperature sensor 510. In other embodiments, the waterway system may further include a second temperature sensor 520. The second temperature sensor 520 may be arranged between the second heating means 220 and the second outlet end 13. The second controller may also be used to control one or more of the flow rate of the outlet water of the flow control assembly 230 and the power of the second heating device 220 based on the temperature detected by the second temperature sensor 520.

The first temperature sensor 510 may detect the temperature of the water stream entering the second heating means 220. The second temperature sensor 520 may detect the temperature of the water stream discharged from the second heating means 220. Therefore, the embodiment of the utility model provides a waterway system can improve the precision of the leaving water temperature of second play water end 13 to stabilize leaving water temperature.

Illustratively, the waterway system may further include a third outlet end 14. The third outlet end 14 may be connected to the outlet of the central filter assembly 300. In some embodiments, the third outlet end 14 can be a normal temperature water outlet end. The user can receive the normal temperature water which is not heated from the third water outlet end 14, so that the use place of the waterway system can be increased.

Illustratively, the waterway system may further include a pre-filter assembly 600. The water inlet of the pre-filter assembly 600 may be connected to the water inlet end 11. The water outlet of the pre-filter assembly 600 may be connected to the water inlet of the first heating module 100 and the water inlet of the central filter assembly 300. The pre-filter assembly 600 may include any type of filter cartridge, whether present or as may become available in the future. The pre-filter assembly 600 can filter water entering the first heating module 100, so as to reduce the generation of scale in the first heating module 100 and prolong the service life of the first heating module 100. In addition, the front filter assembly 600 can primarily filter raw water entering the central filter assembly 300, so that large particle impurities in the raw water are reduced from blocking the central filter assembly 300, and the large particle impurities in the raw water are prevented from damaging the central filter assembly 300.

According to another aspect of the present invention, an integrated sink is provided. The integrated sink may include a first faucet 710, a second faucet 720, and any of the waterway systems described above. The first outlet end 12 may be connected to a first spigot 710. The second water outlet end 13 may be connected to a second tap 720. The integrated water tank with the arrangement can improve the integration level of the integrated water tank, and is convenient for users to use and install. It should be noted that in the embodiment having the third water outlet end 14, the third water outlet end 14 and the second water outlet end 13 can be connected to the second faucet 720 together. The user can control the flow of water out of the second outlet end 13 or the third outlet end 14 by controlling a plurality of valves of the second faucet 720.

Illustratively, the first heating device 120 may also include a kitchen heater. The kitchen heater may comprise a prior art "small kitchen appliance" or the like. A certain amount of water can be stored and heated in the kitchen heater for a user to take when needed. Therefore, the integrated water tank can be integrated with a kitchen heater, the cost of the integrated water tank is reduced, the integration level of the integrated water tank is improved, and appearance parts of each module are reduced.
